Subject: [PATCH 003/399] fix: use playlist NAME when available as its ID
 (#929)

This is particularly used in DASH as the NAME is set from the Representation's ID which is specified to be unique per period and that across periods, the representations with the same ID should be functionally equivalent.
This is important because in DASH, across periods, it's possible for Representations to be re-ordered, and we want to make sure that the reference doesn't get messed up when the period updates.
It still sets up a reference to the playlist via the old name but if the ordering is changed it'll reference the incorrect playlist as it does now.

Subject: [PATCH 007/399] fix: use TIME_FUDGE_FACTOR rather than rounding by
 decimal digits (#881)

Currently, we ran into an issue with roundSignificantDigit because it is rounding integer whole numbers when it seems like it was only made to round floats. This can cause us to download multiple duplicate segments on slow connections. Instead, only round by TIME_FUDGE_FACTOR here. This will prevent us from having to do any rounding at all.

Subject: [PATCH 009/399] feat: Update minimumUpdatePeriod handling (#942)

This is part of a set of upcoming changes to add support for live DASH playback. Specifically, this PR differentiates the handling of 2 cases which were formerly conflated:

- The MPD@minimumUpdatePeriod attribute has a value of 0, indicating that the MPD has no validity after the moment it was retrieved.
- The MPD@minimumUpdatePeriod attribute is absent, indicating the MPD has infinite validity and will never be updated

Subject: [PATCH 010/399] fix: MPD not refreshed if minimumUpdatePeriod is 0
 (#954)

This fixes a bug caused by an oversight in #942. If the MPD@minimumUpdatePeriod is 0 in the first dynamic MPD we load, we should use the media's target duration as the MPD refresh interval, however we need to wait until a playlist has been selected before we can know DashPlaylistLoader.media().targetDuration, otherwise we get a TypeError.

This reverts commit 22694642fc53815f441560f14e36d74232fca9f3.

In testing, we noticed that the Angel One DASH video is broken, so we need to revert this change and fix it later.

Subject: [PATCH 015/399] feat: add experimental buffer based ABR (#886)

This adds a new option `experimentalBufferBasedABR` which turns it on. It uses a moving average playlist selector along with forward buffer checks that gate up and down switching. Right now it is turned off, and we are likely to fiddle with the implementation of this so it should not be relied on right now. We hope to eventually ship what this turns into as the new default ABR for VHS.

Subject: [PATCH 016/399] fix: check tech error before pause loaders (#969)

A failed poster image may trigger an error event from the tech. This shouldn't cause us to pause our loaders, though.
Instead, we should verify that there's an actual error object on the tech before proceeding with pausing the loaders.

Subject: [PATCH 017/399] fix: appendsdone abort and handle multiple id3
 sections. (#971)

appendsdone may cause an abort in segmentloaders which can then cause pendingSegment to be null after we just null checked it. Instead we should check if we have a pendingSegment then trigger appends done and see if an abort happens.

We also want to make sure that if audio contains multiple id3 sections, we support playing back to it as we did in previos versions of VHS.

Subject: [PATCH 019/399] fix(experimentalBufferBasedABR): call selectPlaylist
 and change media on an interval (#978)

This is a followup to #886. There, I noticed that if we get sustained bad network we will time out because we will an opportunity for earlyabort. At first, I tried working around by delaying earlyabort in that case (#966) but as I was getting that ready I kept finding edge cases that we needed to account for. Specifically, the issue is that we only run our ABR algorithm on progress and bandwidthchange events from the segment loader. This means that if the download stalls, we stop run our algorithm and will eventually stall playback. Instead, we should remove earlyabort altogether (f897dde) and set up an interval (currently 250ms) to re-run our ABR algorithm. This means that if the network becomes bad for a sustained period, we will drop down once the buffer allows us but if the network recovers, we will switch up appropriately as well.

Also, the interval is stopped while we're paused.

Fixes #964.

Subject: [PATCH 021/399] fix(playback-watcher): ignore subtitles (#980)

It's possible that a subtitle track will have segments without any text
in them depending on how the subtitles and captions were created.
Therefor, we should ignore it in the playback-watcher where we're
checking for excessive downloads.

Subject: [PATCH 034/399] fix: Wait for EME initialization before appending
 content (#1002)

This is particularly important for Chrome, where, if unencrypted
content is appended before encrypted content and the key session
has not been created, a MEDIA_ERR_DECODE will be thrown once the
encrypted content is reached during playback.

Subject: [PATCH 044/399] fix(experimentalBufferBasedABR): start ABR timer on
 main playlist load (#1026)

Start the timer later, so we don't try to call simpleSelector without a playlist. However, we should add a null-check there just in case.

Fixes #1025

Subject: [PATCH 048/399] chore(demo): clear type on manual source change
 (#1030)

If a user manually changes the url, the type may not be correct anymore.
We should clear it. Given that we auto-detect .m3u8 and .mpd types, it
shouldn't be a big deal and would cause less problems than the incorrect
type being present for the given source.

+
+### Bug Fixes
+
+* if a playlist was last requested less than half target duration, delay retry ([#1038](https://github.com/videojs/http-streaming/issues/1038)) ([2e237ee](https://github.com/videojs/http-streaming/commit/2e237ee))
+* programmatically create Config getters/setters ([8454da5](https://github.com/videojs/http-streaming/commit/8454da5))
+
+### Chores
+
+* **demo:** clear type on manual source change ([#1030](https://github.com/videojs/http-streaming/issues/1030)) ([d39276d](https://github.com/videojs/http-streaming/commit/d39276d))
+* mark many more sources as working ([#1035](https://github.com/videojs/http-streaming/issues/1035)) ([904153f](https://github.com/videojs/http-streaming/commit/904153f))
+* move playback tests to a separate ci run ([#1028](https://github.com/videojs/http-streaming/issues/1028)) ([f1d9f6e](https://github.com/videojs/http-streaming/commit/f1d9f6e))
+* remove replace and update packages ([#1031](https://github.com/videojs/http-streaming/issues/1031)) ([0976212](https://github.com/videojs/http-streaming/commit/0976212))

Subject: [PATCH 066/399] fix: store `transmuxQueue` and `currentTransmux` on
 `transmuxer` instead of globally (#1045)

Prevents separate videos on the page or separate transmuxers from bottlenecking one another.

Subject: [PATCH 067/399] fix: wait for endedtimeline event from transmuxer
 when reaching the end of a timeline (#1058)

Previously, when the end of a timeline was reached (i.e., the last
segment in a given timeline was appended), `endTimeline` would be
called, but the loader would not wait for the event to finish. This
lead to issues where segment information came back after a segment is
considered done with processing, and segment information could be
dropped. This fix waits for the `endedtimeline` message from the
transmuxer before it considers the transmux complete.

Subject: [PATCH 068/399] feat: allow xhr override globally, for super advanced
 use cases only (#1059)

We have the recommended `beforeRequest` method but due to timing, it's not possible to use this to be able to set options for the initial m3u8 manifest as well. This makes it so that the XHR method can be overridden completely.

Subject: [PATCH 070/399] fix: use a separate ProgramDateTime mapping to player
 time per timeline (#1063)

Previously, the ProgramDateTime would map to time 0 at the start of playback, and that mapping would be used for the rest of playback.

However, in the case of a discontinuity, ProgramDateTime can jump (as in, can be a larger difference in time than a single segment duration, e.g., if the encoder went down for a period of time). Because the ProgramDateTime to player time mapping never changed, this led to seeking errors.

This fix uses a mapping of ProgramDateTime to player time per timeline, allowing those "jumps" in time on discontinuities.

Subject: [PATCH 074/399] fix: allow buffer removes when there's no current
 media info in loader (#1070)

Previously, if there wasn't any current media info in the loader, then a
remove of buffered contents would not be processed. This would
intuitively make sense, as if there wasn't current media info, then in
theory there shouldn't be any buffered contents. However, it is possible
for there to be buffered contents without current media info in the event
of a non destructive rendition switch. This was noticed when switching
renditions, expecting a fast quality change to clear the contents and
continue playback at a new rendition. Sometimes the remove wouldn't
happen, so the content would continue to play back the old buffered
content from a different rendition. This fix instead allows the removes
so long as there is starting media info (which is available after first
segment download).

Subject: [PATCH 079/399] fix: live dash segment changes should be considered a
 playlist update (#1065)

Currently dash content goes off of the number attribute for segments to determine the mediaSequence. This is problematic as the first segment is almost always listed as 1. So in essence when we request the playlist again the media sequence will be the same, and likely the amount of segments will be the same, so we will determine that this playlist update didn't update anything at all.

+
+### Chores
+
+* Get test coverage working again with mock/sync worker ([#1094](https://github.com/videojs/http-streaming/issues/1094)) ([035e8c0](https://github.com/videojs/http-streaming/commit/035e8c0))

Subject: [PATCH 112/399] fix: don't clear DASH minimum update period timeout
 on pause of a media loader (#1118)

Previously, for DASH, pausing a media loader would end up pausing the
main loader as well (via removal of the main loader's minimum update
period). For live streams which required manifest refreshes, this meant
that on media changes, the main loader would be paused and sometimes
never resumed.

This change ensures that when a media loader is paused it won't remove
the main loader's minimum update period timeout.

In addition, a change was made so that loading a main DASH playlist
loader recreates a minimum update period timeout if the main DASH loader
was previously paused (and the timeout cleared).

Subject: [PATCH 122/399] fix: set audio status on loaders when setting up
 media groups (#1126)

Although the audio status is set in onTrackChanged for media groups, and
the function is called when the media groups are first set up, the track
is not always considered changed. This means that for demuxed audio, the
main loader may still think it should be using its own audio itself,
leading to issues when crossing discontinuities (i.e., the main loader
will cross the discontinuity before waiting for the audio loader to be
ready, leading to audio timestamps that aren't correct).

This change ensures that the audio status is set on setup, regardless of
whether the track is considered changed. Subsequent changes are handled
in onTrackChanged.

Subject: [PATCH 133/399] feat: do fast rendition changes on fullscreen changes
 and user actions (#1074)

Deprecate smoothQualityChange_ on the MPC, but otherwise, always do fast quality change whenever a user requests a rendition change and on fullscreen change

-When the `smoothQualityChange` property is set to `true`, a manual quality
-change triggered via the [representations API](#vhsrepresentations) will use
-smooth quality switching rather than the default fast (buffer-ejecting)
-quality switching. Using smooth quality switching will mean no loading spinner
-will appear during quality switches, but will cause quality switches to only
-be visible after a few seconds.
+smoothQualityChange is deprecated and will be removed in the next major version of VHS.
 
-Note that this _only_ affects quality changes triggered via the representations
-API; automatic quality switches based on available bandwidth will always be
-smooth switches.
+Instead of its prior behavior, smoothQualityChange will now call fastQualityChange, which
+clears the buffer, chooses a new rendition, and starts loading content from the current
+playhead position.

Subject: [PATCH 134/399] feat: allow clients to limit the number of times a
 playlist attempts to reload following an error (#1098)

Introduce a new option `maxPlaylistRetries`, which defaults to Infinity to match existing behavior. If set, this will cause a playlist to be excluded indefinitely when the threshold is crossed. When a playlist is requested successfully, the count is reset.

If a stream has multiple playlists, all playlists will need to cross the max retries threshold for playback to completely fail.

Subject: [PATCH 135/399] feat: Caption services (608/708) metadata (#1138)

Add an option for caption services metadata in case the user wants to specify labels for 608/708 captions, override the ones provided in the manifest, or needs to add more information like character encoding (this isn't currently available but will be added some time in the future).
For HLS, an EXT-X-MEDIA tag can be specified with an INSTREAM-ID attribute. We already support this. https://datatracker.ietf.org/doc/html/draft-pantos-hls-rfc8216bis-08#section-4.4.6.1
This PR updated mpd-parser which uses the ANSI 214 supplemental spec section 7.2 to parse out the same information from MPD files. videojs/mpd-parser#131.

Adds a property called captionServices which has properties of the caption service IDs like CC1 or SERVICE1 and allows a user to specify a language and label.

+
+For 608 captions, the service names are `CC1`, `CC2`, `CC3`, and `CC4`. For 708 captions, the service names are `SERVICEn` where `n` is a digit between `1` and `63`.

Subject: [PATCH 157/399] test: refactor tests so that players/blob urls/ and
 media elements are cleaned up (#1174)

Chrome 92 introduced a limit (75) on the number of media elements that can exist in a page at a time and we were going over that limit in our tests, causing them to fail.

Subject: [PATCH 164/399] chore: update the demo page (#1184)

Using bootstrap styles and tabs, update the demo page and bring in some stuff from the stats page.

The two main things that are missing right now are the bitrate switching and the timed metadata graphs, though, I think those aren't used as much. I figured we can bring what I have so far, and we can work on the others later on. For example, I want to migrate the representations dropdown to be a bit closer to what's in the stats page instead.

I kept the old index page as old-index.html and have the main page redirect there if we're on IE11, because the bootstrap version used doesn't support IE11. Hopefully, we won't be supporting IE11 for long, and we can delete this once we drop support.

Subject: [PATCH 168/399] chore: various demo page fixes and enhancements
 (#1186)

* Adds back in the run tests link (which is removed on netlify).
* Correctly disposes of stats on player dispose.
* Defaults to the new liveui
* Saves the state of `player.muted()` to the test page state so that muting/unmuting the player is saved across reloads.
* Moves the preloaded source dropdown to the top of the form

Subject: [PATCH 189/399] fix: Various fixes for llhls so that we start closer
 to live, and stay closer to live (#1201)

* Don't switch renditions when the pending rendition is the rendition we would switch to
* Don't switch renditions before playback starts for llhls
* Don't set seekable until all source buffers have been created
* Take into account parts and preload segments when during duration calculations
* Reset the segment loader on rendition change for live streams, still resync for vod
* Try to choose an independent first part if we have no buffered data
* Determine if we made a bad part guess for our segment download

Subject: [PATCH 191/399] feat: Add an option to use the NetworkInformation
 API, when available (#1218)

When enabled, if the NetworkInformation API is available, it will be used for bandwidth estimation, If our estimation is greater than 10MBps and the downlink returns 10MBps, then our estimation is used.

Subject: [PATCH 196/399] fix: fix seekable not updating after the first change
 for live streams (#1233)

This removes a check for hasCreatedSourceBuffers that short circuited
onSyncInfoUpdate_. It also adds a comment about how to add the check
in the future, as a simple change of truthiness leads to other issues
in playing back a live stream.

Subject: [PATCH 200/399] feat: use new mpd-parser API for handling live DASH
 refreshes (#1231)

In order to support the new mpd-parser API, whenever a DASH manifest
refreshes, the prior parsed manifest object needs to be passed in as
`previousManifest`. This change adds support for that.

+# A Walk Through VHS
+
+Today we're going to take a walk through VHS. We'll start from a manifest URL and end with video playback.
+
+The purpose of this walk is not to see every piece of code, or define every module. Instead it's about seeing the most important parts of VHS. The goal is to make VHS more approachable.
+
+Lets start with a video tag:
+
+```html
+<video>
+  <source src="http://example.com/manifest.m3u8" type="application/x-mpegURL">
+</video>
+```
+
+The source, `manifest.m3u8`, is an HLS manifest. You can tell from the `.m3u8` extension and the `type`.
+
+Safari (and a few other browsers) will play that video natively, because Safari supports HLS content. However, other browsers don't support native playback of HLS and will fail to play the video.
+
+VHS provides the ability to play HLS (and DASH) content in browsers that don't support native HLS (and DASH) playback.
+
+Since VHS is a part of Video.js, let's set up a Video.js player for the `<video>`:
+
+```html
+<link href="//vjs.zencdn.net/7.10.2/video-js.min.css" rel="stylesheet">
+<script src="//vjs.zencdn.net/7.10.2/video.min.js"></script>
+
+<video-js id="myPlayer" class="video-js" data-setup='{}'>
+  <source src="http://example.com/manifest.m3u8" type="application/x-mpegURL">
+</video-js>
+```
+
+Video.js does a lot of things, but in the context of VHS, the important feature is a way to let VHS handle playback of the source. To do this, VHS is registered as a Video.js Source Handler. When a Video.js player is created and provided a `<source>`, Video.js goes through its list of registered Source Handlers, including VHS, to see if they're able to play that source.
+
+In this case, because it's an HLS source, VHS will tell Video.js "I can handle that!" From there, VHS is given the URL and it begins its process.
+
+## videojs-http-streaming.js
+
+`VhsSourceHandler` is defined at the [bottom of src/videojs-http-streaming.js](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/videojs-http-streaming.js#L1226-L1233).
+
+The function which Video.js calls to see if the `VhsSourceHandler` can handle the source is aptly named `canHandleSource`.
+
+Inside `canHandleSource`, VHS checks the source's `type`. In our case, it sees `application/x-mpegURL`, and, if we're running in a browser with MSE, then it says "I can handle it!" (It actually says "maybe," because in life there are few guarantees, and because the spec says to use "maybe.")
+
+### VhsSourceHandler
+
+Since VHS told Video.js that it can handle the source, Video.js passes the source to `VhsSourceHandler`'s `handleSource` function. That's where VHS really gets going. It creates a new `VhsHandler` object, merges some options, and performs initial setup. For instance, it creates listeners on some `tech` events.
+
+```mermaid
+flowchart TD
+  VhsSourceHandler --> VhsHandler
+```
+
+> :information_source: **What should be put in VhsHandler?**
+>
+> videojs-http-streaming.js is a good place for interfacing with Video.js and other plugins, isolating integrations from the rest of the code.
+>
+> Here are a couple of examples of what's done within videojs-http-streaming.js:
+> * most EME handling for DRM and setup of the [videojs-contrib-eme plugin](https://github.com/videojs/videojs-contrib-eme)
+> * mapping/handling of options passed down via Video.js
+
+## MasterPlaylistController
+
+One critical object that `VhsHandler`'s constructor creates is a new `MasterPlaylistController`.
+
+```mermaid
+flowchart TD
+  VhsSourceHandler --> VhsHandler
+  VhsHandler --> MasterPlaylistController
+```
+
+`MasterPlaylistController` is not a great name, and has grown in size to be a bit unwieldy, but it's the hub of VHS. Eventually, it should be broken into smaller pieces, but for now, it handles the creation and management of most of the other VHS modules. Its code can be found in [src/master-playlist-controller.js](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/master-playlist-controller.js).
+
+The best way to think of `MasterPlaylistController` is as Tron's Master Control Program, though hopefully it isn't as evil.
+
+`MasterPlaylistController` is a lot to say. So we often refer to it as MPC.
+
+If you need to find a place where different modules communicate, you will probably end up in MPC. Just about all of `VhsHandler` that doesn't interface with Video.js or other plugins, interfaces with MPC.
+
+MPC's [constructor](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/master-playlist-controller.js#L148) does a lot. Instead of listing all of the things it does, let's go step-by-step through the main ones, passing the source we had above.
+
+```html
+<video-js id="myPlayer" class="video-js" data-setup='{}'>
+  <source src="http://example.com/manifest.m3u8" type="application/x-mpegURL">
+</video-js>
+```
+
+Looking at the `<source>` tag, `VhsSourceHandler` already used the "type" to tell Video.js that it could handle the source. `VhsHandler` took the manifest URL, in this case "manifest.m3u8" and provided it to the constructor of MPC.
+
+The first thing that MPC must do is download that source, but it doesn't make the request itself. Instead, it creates [this.masterPlaylistLoader_](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/master-playlist-controller.js#L264-L266).
+
+```mermaid
+flowchart TD
+  VhsSourceHandler --> VhsHandler
+  VhsHandler --> MasterPlaylistController
+  MasterPlaylistController --> PlaylistLoader
+```
+
+`masterPlaylistLoader_` is an instance of either the [HLS PlaylistLoader](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/playlist-loader.js#L379) or the [DashPlaylistLoader](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/dash-playlist-loader.js#L259).
+
+The names betray their use. They load the playlist. The URL ("manifest.m3u8" here) is given, and the manifest/playlist is downloaded and parsed. If the content is live, the playlist loader also handles refreshing the manifest. For HLS, where manifests point to other manifests, the playlist loader requests those as well.
+
+As for parsing, for HLS, the manifest responses are parsed using [m3u8-parser](https://github.com/videojs/m3u8-parser). For DASH, the manifest response is parsed using [mpd-parser](https://github.com/videojs/mpd-parser). The output of these parsers is a JSON object that VHS understands. The main structure can be seen in the READMEs, e.g., [here](https://github.com/videojs/m3u8-parser#parsed-output).
+
+So what was once a URL in a `<source>` tag was requested and parsed into a JSON object like the following:
+
+```
+Manifest {
+  playlists: [
+    {
+      attributes: {},
+      Manifest
+    }
+  ],
+  mediaGroups: { ... },
+  segments: [ ... ],
+  ...
+}
+```
+
+Many properties are removed for simplicity. This is a top level manifest (often referred to as a master or main manifest), and within it there are playlists, each playlist being a Manifest itself. Since the JSON "schema" for main and media playlists is the same, you will see irrelevant properties within any given manifest object. For instance, you might see a `targetDuration` property on the main manifest object, though a main manifest doesn't have a target duration. You can ignore irrelevant properties. Eventually they should be cleaned up, and a proper schema defined for manifest objects.
+
+MPC will also use `masterPlaylistLoader_` to select which media playlist is active (e.g., the 720p rendition or the 480p rendition), so that `masterPlaylistLoader_` will only need to refresh that individual playlist if the stream is live.
+
+> :information_source: **Future Work**
+>
+> The playlist loaders are not the clearest modules. Work has been started on improvements to the loaders and how we use them: https://github.com/videojs/http-streaming/pull/1208
+>
+> That work makes them much easier to read, but will require changes throughout the rest of the code before the old PlaylistLoader and DashPlaylistLoader code can be removed.
+
+### Media Source Extensions
+
+The next thing MPC needs to do is set up a media source for [Media Source Extensions](https://www.w3.org/TR/media-source/). Specifically, it needs to create [this.mediaSource](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/master-playlist-controller.js#L210) and its associated [source buffers](https://github.com/videojs/http-streaming/blob/main/src/master-playlist-controller.js#L1818). These are where audio and video data will be appended, so that the browser has content to play. But those aren't used directly. Because source buffers can only handle one operation at a time, [this.sourceUpdater_](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/master-playlist-controller.js#L234) is created. `sourceUpdater_` is a queue for operations performed on the source buffers. That's pretty much it. So all of the MSE pieces for appending get wrapped up in `sourceUpdater_`.
+
+## Segment Loaders
+
+The SourceUpdater created for MSE above is passed to the segment loaders.
+
+[this.mainSegmentLoader_](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/master-playlist-controller.js#L271-L275) is used for muxed content (audio and video in one segment) and for audio or video only streams.
+
+[this.audioSegmentLoader_](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/master-playlist-controller.js#L278-L281) is used when the content is demuxed (audio and video in separate playlists). 
+
+```mermaid
+flowchart TD
+  VhsSourceHandler --> VhsHandler
+  VhsHandler --> MasterPlaylistController
+  MasterPlaylistController --> PlaylistLoader
+  MasterPlaylistController --> SourceUpdater
+  MasterPlaylistController --> SegmentLoader
+```
+
+Besides options and the `sourceUpdater_` from MPC, the segment loaders are given a [playlist](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/segment-loader.js#L988). This playlist is a media playlist from the `masterPlaylistLoader_`. So looking back at our parsed manifest object:
+
+```
+Manifest {
+  playlists: [
+    {
+      attributes: {},
+      Manifest
+    }
+  ],
+  mediaGroups: { ... },
+  segments: [ ... ],
+  ...
+}
+```
+
+The media playlists were those objects found in the `playlists` array. Each segment loader is given one of those.
+
+Segment Loader uses the provided media playlist to determine which segment to download next. It performs this check when [monitorBuffer_](https://github.com/videojs/http-streaming/blob/main/src/segment-loader.js#L1300) is called, which ultimately runs [chooseNextRequest_](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/segment-loader.js#L1399). `chooseNextRequest_` looks at the buffer, the current time, and a few other properties to choose what segment to download from the `playlist`'s `segments` array.
+
+### Choosing Segments to Download
+
+VHS uses a strategy called `mediaIndex++` for choosing the next segment, see [here](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/segment-loader.js#L1442). This means that, if segment 3 was previously requested, segment 4 should be requested next, and segment 5 after that. Those segment numbers are determined by the HLS [#EXT-X-MEDIA-SEQUENCE tag](https://datatracker.ietf.org/doc/html/draft-pantos-hls-rfc8216bis-10#section-4.4.3.2).
+
+If there are no seeks or rendition changes, `chooseNextRequest_` will rely on the `mediaIndex++` strategy.
+
+If there are seeks or rendition changes, then `chooseNextRequest_` will look at segment timing values via the `SyncController` (created previously in MPC), the current time, and the buffer, to determine what the next segment should be, and what it's start time should be (to position it on the timeline).
+
+```mermaid
+flowchart TD
+  VhsSourceHandler --> VhsHandler
+  VhsHandler --> MasterPlaylistController
+  MasterPlaylistController --> PlaylistLoader
+  MasterPlaylistController --> SourceUpdater
+  MasterPlaylistController --> SegmentLoader
+  SegmentLoader --> SyncController
+```
+
+The `SyncController` has various [strategies](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/sync-controller.js#L16) for ensuring that different renditions, which can have different media sequence and segment timing values, can be positioned on the playback timeline successfully. (It is also be [used by MPC](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/master-playlist-controller.js#L1477) to establish a `seekable` range.)
+
+### Downloading and Appending Segments
+
+If the buffer is not full, and a segment was chosen, then `SegmentLoader` will download and append it. It does this via a [mediaSegmentRequest](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/segment-loader.js#L2489).
+
+
+```mermaid

+  VhsHandler --> MasterPlaylistController
+  MasterPlaylistController --> PlaylistLoader
+  MasterPlaylistController --> SourceUpdater
+  MasterPlaylistController --> SegmentLoader
+  SegmentLoader --> SyncController
+  SegmentLoader --> mediaSegmentRequest
+```
+
+`mediaSegmentRequest` takes a lot of arguments. Most are callbacks. These callbacks provide the data that `SegmentLoader` needs to append the segment. It includes the timing information of the segment, captions, and the segment data.
+
+When the `SegmentLoader` receives timing info events, it can update the source buffer's timestamp offset (via `SourceUpdater`).
+
+When the `SegmentLoader` receives segment data events, it can append the data to the source buffer (via `SourceUpdater`).
+
+```mermaid
+flowchart TD
+  VhsSourceHandler --> VhsHandler
+  VhsHandler --> MasterPlaylistController
+  MasterPlaylistController --> PlaylistLoader
+  MasterPlaylistController --> SourceUpdater
+  MasterPlaylistController --> SegmentLoader
+  SegmentLoader --> SyncController
+  SegmentLoader --> mediaSegmentRequest
+  SegmentLoader --> SourceUpdater
+```
+
+## mediaSegmentRequest
+
+We talked a bit about how `SegmentLoader` uses `mediaSegmentRequest`, but what does [mediaSegmentRequest](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/media-segment-request.js#L941) do?
+
+Besides downloading segments, `mediaSegmentRequest` [decrypts](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/media-segment-request.js#L621) AES encrypted segments, probes [MP4](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/media-segment-request.js#L171) and [TS](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/media-segment-request.js#L375) segments for timing info, and [transmuxes](https://github.com/videojs/http-streaming/blob/0964cb4827d9e80aa36f2fa29e35dad92ca84111/src/media-segment-request.js#L280) TS segments into MP4s using [mux.js](https://github.com/videojs/mux.js) so they can be appended to the source buffers.
+
+```mermaid
+flowchart TD
+  VhsSourceHandler --> VhsHandler
+  VhsHandler --> MasterPlaylistController
+  MasterPlaylistController --> PlaylistLoader
+  MasterPlaylistController --> SourceUpdater
+  MasterPlaylistController --> SegmentLoader
+  SegmentLoader --> SyncController
+  SegmentLoader --> mediaSegmentRequest
+  SegmentLoader --> SourceUpdater
+  mediaSegmentRequest --> mux.js
+```
+
+## Video playback begins
+
+The video can start playing as soon as there's enough audio and video (for muxed streams) in the buffer to move the playhead forwards. So playback may begin before the `SegmentLoader` completes its full cycle.
+
+But once `SegmentLoader` does finish, it starts the process again, looking for new content.

Per mdn, _The value is never greater than 10 Mbps, as a non-standard anti-fingerprinting measure_. Given this, if bandwidth estimates from both the player and networkInfo are >= 10 Mbps, the player will use the larger of the two values as its bandwidth estimate.

+# Migration Guide from 2.x to 3.x
+
+## All `hls-` events were removed
+All `hls-` prefixed events were removed. If you were listening to any of those events, you should switch the prefix from `hls-` to `vhs-`.
+For example, if you were listening to `hls-gap-skip`:
+```js
+player.tech().on('hls-gap-skip', () => {
+  console.log('a gap has been skipped');
+});
+```
+you should now listening to `vhs-gap-skip`:
+```js
+player.tech().on('vhs-gap-skip', () => {
+  console.log('a gap has been skipped');
+});
+```
+
+See [VHS Usage Events](../#vhs-usage-events) for more information on these events.
+
+## player properties for accessing VHS
+All player level properties to access VHS have been removed.
+
+If you were using any of the following:
+* `player.vhs`
+* `player.hls`
+* `player.dash`
+
+You should switch that to accessing the `vhs` property on the tech like so:
+```js
+player.tech().vhs
+```

In the static mode, the Main and Media playlists are fixed. The player is guaranteed that the set of video segments referenced by those playlists will not change over time.
 
 Live mode can work in one of two ways. For truly live events, the most common configuration is for each individual Media Playlist to only include the latest video segment and a small number of consecutive previous segments. In this mode, the player may be able to seek backwards a short time in the video but probably not all the way back to the beginning. In the other live configuration, new video segments can be appended to the Media Playlists but older segments are never removed. This configuration allows the player to seek back to the beginning of the stream at any time during the broadcast and transitions seamlessly to the static stream type when the event finishes.

 During VOD playback, the loader will move quickly to the HAVE_METADATA state and then stay there unless a quality switch request sends it to SWITCHING_MEDIA while it fetches an alternate playlist. The loader enters the HAVE_CURRENT_METADATA when a live stream is detected and it's time to refresh the current media playlist to find out about new video segments.
 
 ### HLS Tech
-Currently, the HLS project integrates with [video.js](http://www.videojs.com/) as a [tech](https://github.com/videojs/video.js/blob/master/docs/guides/tech.md). That means it's responsible for providing an interface that closely mirrors the `<video>` element. You can see that implementation in [videojs-http-streaming.js](../src/videojs-http-streaming.js), the primary entry point of the project.

 ### Previous Behavior
 
-Until version 1.9.0 of [VHS], we thought that [DPL] could skip the `HAVE_NOTHING` and `HAVE_MASTER` states, as no other XHR requests are needed once the MPD has been downloaded and parsed. However, this is incorrect as there are some Presentations that signal the use of a "Segment Index box" or `sidx`. This `sidx` references specific byte ranges in a file that could contain media or potentially other `sidx` boxes.

This `sidx` references specific byte ranges in a file that could contain media or potentially other `sidx` boxes.
 
-A DASH MPD that describes a `sidx` is therefore similar to an HLS master manifest, in that the MPD contains references to something that must be requested and parsed first before references to media segments can be obtained. With this in mind, it was necessary to update the initialization and state transitions of [DPL] to allow further XHR requests to be made after the initial request for the MPD.

 ### Current Behavior
 
-In [this PR](https://github.com/videojs/http-streaming/pull/386), the [DPL] was updated to go through the `HAVE_NOTHING` and `HAVE_MASTER` states before arriving at `HAVE_METADATA`. If the MPD does not contain `sidx` boxes, then this transition happens quickly after `load()` is called, spending little time in the `HAVE_MASTER` state.

-The initial media selection for `masterPlaylistLoader` is made in the `loadedplaylist` handler located in [MasterPlaylistController][mpc]. We now use `hasPendingRequest` to determine whether to automatically select a media playlist for the `masterPlaylistLoader` as a fallback in case one is not selected by [MPC]. The child [DPL]s are created with a media playlist passed in as an argument, so this fallback is not necessary for them. Instead, that media playlist is saved and auto-selected once we enter the `HAVE_MASTER` state.

+While most of the [mux.js pipeline](/docs/diagram.png) supports pushing pieces of data (and should support LHLS by default), its "flushes" to send transmuxed data back to the caller expected full segments.
 
 Much of the pipeline was reused, however, the top level audio and video segment streams, as well as the entry point, were rewritten so that instead of providing a full segment on flushes, each frame of video was provided individually (audio frames still flush as a group). The new concept of partial flushes was added into the pipeline to handle this case.

 ### Test Changes
 
-Some tests were removed because they were no longer relevant after the change to creating source buffers later. For instance, `waits for both main and audio loaders to finish before calling endOfStream if main loader starting media is unknown` no longer can be tested by waiting for an audio loader response and checking for end of stream, as the test will time out since MasterPlaylistController will wait for track info from the main loader before the source buffers are created. That condition is checked elsewhere.

Subject: [PATCH 225/399] feat: enable LLHLS support by default and remove
 experimental prefix on options (#1301)

* `experimentalBufferBasedABR` becomes `bufferBasedABR`
* `experimentalLLHLS` becomes `llhls` (and is now `true` by default)
* `experimentalExactManifestTimings` becomes `exactManifestTimings`
* `experimentalLeastPixelDiffSelector` becomes `leastPixelDiffSelector`

BREAKING CHANGE: This renames four experimental options to no longer be experimental and enables Low Latency HLS support by default (`llhls: false` will still disable it, if desired).

Subject: [PATCH 226/399] refactor: clean up parameters of excludePlaylist
 (#1304)

Co-authored-by: Pat O'Neill <pgoneill@gmail.com>

`PlaylistController#excludePlaylist` now takes a single object with 3 properties:

* `playlistToExclude`, defaults to the currently selected playlist
* `error`
* `playlistExclusionDuration`, defaults to the value passed in the constructor

BREAKING CHANGE: This changes the arguments for the `PlaylistController#excludePlaylist` method to take a single object instead of multiple arguments.

Subject: [PATCH 227/399] test: change source for live DASH playback test to
 fix test failures (#1303)

The current live DASH playback test source uses a source where segments
are referenced by a SegmentTemplate and duration, but the server
doesn't have time syncing and appears to be about two minutes behind
local time. This leads to requests for segments beyond expected and
occasional failures.

Until that issue is fixed in VHS, switch to a live source that uses
SegmentTemplate, to be a more reliable basic live DASH playback test.

 builds (#1320)

BREAKING CHANGE: This updates bundled libraries to no longer be transpiled to ES5, which means IE will no longer be supported.

+Run subtitles.vtt through subtle crypto. As an example:
+
+```javascript
+const fs = require('fs');
+const { subtle } = require('crypto').webcrypto;
+
+// first segment has media index 0, so should have the following IV
+const DEFAULT_IV = new Uint8Array([0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]);
+
+const getCryptoKey = async (bytes, iv = DEFAULT_IV) => {
+  const algorithm = { name: 'AES-CBC', iv };
+  const extractable = true;
+  const usages = ['encrypt', 'decrypt'];
+
+  return subtle.importKey('raw', bytes, algorithm, extractable, usages);
+};
+
+const run = async () => {
+  const keyFilePath = process.argv[2];
+  const segmentFilePath = process.argv[3];
+
+  const keyBytes = fs.readFileSync(keyFilePath);
+  const segmentBytes = fs.readFileSync(segmentFilePath);
+
+  const key = await getCryptoKey(keyBytes);
+  const encryptedBytes = await subtle.encrypt({
+    name: 'AES-CBC',
+    iv: DEFAULT_IV,
+  }, key, segmentBytes);
+
+  fs.writeFileSync('./encrypted.vtt', new Buffer(encryptedBytes));
+
+  console.log(`Wrote ${encryptedBytes.length} bytes to encrypted.vtt:`);
+};
+
+run();
+```
+
+To use the script:
+
+```
+$ node index.js encryptionKey.key subtitles.vtt
+```

+
+
+### BREAKING CHANGES
+
+* **package:** This updates bundled libraries to no longer be transpiled to ES5, which means IE will no longer be supported.
+* This changes the arguments for the `PlaylistController#excludePlaylist` method to take a single object instead of multiple arguments.
+* This renames four experimental options to no longer be experimental and enables Low Latency HLS support by default (`llhls: false` will still disable it, if desired).
+* rename PlaylistController
+* rename HAVE_MASTER to HAVE_MAIN_MANIFEST
+* playlist loaders updateMain and .main prop rename
+* manifest.js exports mainForMedia and addPropertiesToMain
+* rename media groups prop to isMainPlaylist
+* rename property to mainPlaylistLoader_
+* rename to PlaylistController#main()
+* This removes support entirely for IE11 (and older) as well as any other platforms that do not support ES6.
+* remove ^6 from the dependency version ranges.
+* Skips detected gaps immediately instead of waiting the duration of the gap before skipping
+* Removes deprecated `smoothQualityChange` option
+* remove deprecated options, properties, events.
+* remove handleManifestRedirects option. Now XHR.responseURL will always be used when available.

Subject: [PATCH 241/399] fix: resume loading on segment timeout for
 `bufferBasedABR` (#1333)

Previously, if there was a segment timeout and
`experimentalBufferBasedABR` was set to `true`, then the main segment
loader would stay in a `READY` state and never resume loading segments.
This is because the buffer based ABR path doesn't follow the same flow
as non buffer based ABR, where a new playlist would be loaded
immediately and it would trigger a load. Buffer based ABR may determine
that no rendition change should be made, despite the timeout, leading
to nothing happening. This change makes the call to load explicit, but
only for buffer based ABR on timeouts.

+### Chores
+
+* **docs:** Remove outdated information in collaborators' guide ([#1271](https://github.com/videojs/http-streaming/issues/1271)) ([6100750](https://github.com/videojs/http-streaming/commit/6100750))
+* **package:** update dependencies to use new ES6 builds ([#1320](https://github.com/videojs/http-streaming/issues/1320)) ([9ae6695](https://github.com/videojs/http-streaming/commit/9ae6695))

+
+
+### BREAKING CHANGES
+
+* **package:** manifests with tags lacking colons (:) are no longer supported
+* **package:** This updates bundled libraries to no longer be transpiled to ES5, which means IE will no longer be supported.
+* This changes the arguments for the `PlaylistController#excludePlaylist` method to take a single object instead of multiple arguments.
+* This renames four experimental options to no longer be experimental and enables Low Latency HLS support by default (`llhls: false` will still disable it, if desired).
+* rename PlaylistController
+* rename HAVE_MASTER to HAVE_MAIN_MANIFEST
+* playlist loaders updateMain and .main prop rename
+* manifest.js exports mainForMedia and addPropertiesToMain
+* rename media groups prop to isMainPlaylist
+* rename property to mainPlaylistLoader_
+* rename to PlaylistController#main()
+* This removes support entirely for IE11 (and older) as well as any other platforms that do not support ES6.
+* remove ^6 from the dependency version ranges.
+* Skips detected gaps immediately instead of waiting the duration of the gap before skipping
+* Removes deprecated `smoothQualityChange` option
+* remove deprecated options, properties, events.
+* remove handleManifestRedirects option. Now XHR.responseURL will always be used when available.

Subject: [PATCH 245/399] Fix: In-manifest VTT iOS MSE issue (#1360)

* fix: Add exception guard for VTT parsing state if vtt.js is not loaded for any reasons.

* fix: Do not override native for all iOS/iPadOS browsers

* fix: Add guard for vtt-segment-loader to actually load vtt.js in case we do not have it loaded

* chore: fix eslit errors

* chore: Add loadVttJs test

* chore: Add test for parse exception if no vtt.js is loaded for any reason

Subject: [PATCH 249/399] fix: CMAF HLS. Source buffer change type is called
 with wrong codecs sometimes when append segment without init data because of
 a race condition. (#1375)

* Get Codecs: Always use playlist for current pending segment instead of currently loaded playlist.

* Clear active segment id during reset everything

+the function with your own implementation. Instead, `xhr` provides
+the ability to specify `onRequest` and `onResponse` hooks which take a 
+callback function as a parameter as well as `offRequest` and `offResponse` 
+functions which will remove a callback function from the `onRequest` or 
+`onResponse` set if it exists. 
+
+The `onRequest(callback)` function takes a `callback` function that will pass the xhr `request`
+Object to that callback. These callbacks are called synchronously, in the order registered
+and act as pre-request hooks for modifying the xhr `request` Object prior to making a request.
+
+Example:
+```javascript
+const playerRequestHook = (request) => {
+  const requestUrl = new URL(request.uri);
+  requestUrl.searchParams.set('foo', 'bar');
+  request.uri = requestUrl.href;
+};
+player.tech().vhs.xhr.onRequest(playerRequestHook);
+```
+
+The `onResponse(callback)` function takes a `callback` function that will pass the xhr
+`request`, `error`, and `response` Objects to that callback. These callbacks are called
+in the order registered and act as post-request hooks for gathering data from the
+xhr `request`, `error` and `response` Objects.
+
+Example:
+```javascript
+const playerResponseHook = (request, error, response) => {
+  const bar = response.headers.foo
+};
+player.tech().vhs.xhr.onResponse(playerResponseHook);
+```
+
+The `offRequest` function takes a `callback` function, and will remove that function from
+the collection of `onRequest` hooks if it exists.
+
+Example:
+```javascript
+player.tech().vhs.xhr.offRequest(playerRequestHook);
+```
+
+The `offResponse` function takes a `callback` function, and will remove that function from
+the collection of `offResponse` hooks if it exists.
+
+Example:
+```javascript
+player.tech().vhs.xhr.offResponse(playerResponseHook);
+```
+Additionally a `beforeRequest` function can be defined, 
+that will be called with an object containing the options that will be used 
+to create the xhr request.
+
+Note: any registered `onRequest` hooks, are called _after_ the `beforeRequest` function, so xhr
+options modified by this function may be further modified by these hooks.

+Note: This callback *MUST* return an `options` Object as the `xhr` wrapper and each `onRequest`
+hook receives the returned `options` as a parameter.

+
+If access to the `xhr` Object is required prior to the `xhr.send` call, an `options.beforeSend` 
+callback can be set within an `onRequest` callback function that will pass the `xhr` Object

Subject: [PATCH 295/399] feat: Add feature flag to calculate timestampOffset
 for each segment to handle streams with corrupted pts or dts timestamps
 (#1426)

* Use audio/video start time info from Transmuxer instead of probeTs because Transmuxer aligns time between audio and video in the timestampRollover stream.

* Add a feature flag to calculate timestampOffset for each segment, regardless of its timeline, so timestampOffset should always be valid.

+# Content Steering
+
+Content Steering provides content creators a method of runtime control over
+the location from which segments are fetched via a content steering server and
+pathways defined in the content manifest. For a working example visit
+https://www.content-steering.com/.
+
+HLS and DASH each define their own specific Content Steering tags and properties
+that prescribe how the client should fetch the content steering manifest as well
+as make steering decisions. `#EXT-X-CONTENT-STEERING` and `<ContentSteering>` respectively.
+
+For reference, HLS spec section 4.4.6.6:
+https://datatracker.ietf.org/doc/html/draft-pantos-hls-rfc8216bis#section-4.4.6.6
+
+DASH-IF:
+https://dashif.org/docs/DASH-IF-CTS-00XX-Content-Steering-Community-Review.pdf
+
+Both protocols rely on a content steering server to provide steering guidance.
+VHS will request the content steering manifest from the location defined in the
+content steering tag in the `.m3u8` or `.mpd` and refresh the steering manifest
+at an interval defined in that manifest.
+
+A content steering manifest response will look something like this:
+```
+{
+ "VERSION": 1,
+ "TTL": 300,
+ "RELOAD-URI": "https://steeringservice.com/app/instance12345?session=abc",
+ "CDN-PRIORITY": ["beta","alpha"]
+}
+```
+`CDN-PRIORITY` represents either `PATHWAY-PRIORITY` for HLS or `SERVICE-LOCATION-PRIORITY` for DASH. This list of keys in priority order will match with either a `PATHWAY-ID` or `serviceLocation` (HLS and DASH respectively) associated with a location where VHS can fetch segments.
+
+VHS will attempt to fetch segments from the locations defined in the steering manifest response in the order. Then, during playback, VHS will provide quality of experience metrics back to the steering server which can adjust the steering guidance accordingly.
+

The loader enters the HAVE_CURRENT_METADATA when a live stream is detected and it's time to refresh the current media playlist to find out about new video segments.

This option was introduced to align with DTS-based browsers. This option affects only transmuxed data (eg: transport stream).

 If true, this will take the device pixel ratio into account when doing rendition switching. This means that if you have a player with the width of `540px` in a high density display with a device pixel ratio of 2, a rendition of `1080p` will be allowed.
 This setting is `false` by default.
 
+##### customPixelRatio
+* Type: `number`
+* can be used as an initialization option.
+
+If set, this will take the initial player dimensions and multiply it by a custom ratio when the player automatically selects renditions. This means that if you have a player where the dimension is `540p`, with a custom pixel ratio of `2`, a rendition of `1080p` or a lower rendition closest to this value  will be chosen. Additionally, if you have a player where the dimension is `540p`, with a custom pixel ratio of `0.5`, a rendition of `270p` or a lower rendition closest to this value will be  chosen. When the custom pixel ratio is 0, the lowest available rendition will be selected.
+
+It is worth noting that if the player dimension multiplied by the custom pixel ratio is greater than any available rendition resolution, a rendition will be selected based on bandwidth, and the player dimension will be disregarded.
+
+`limitRenditionByPlayerDimensions` must be `true` in order for this feature to be enabled. This is the default value.
+
+If `useDevicePixelRatio` is set to `true`, the custom pixel ratio will be prioritized and overwrite any previous pixel ratio.

Subject: [PATCH 368/399] feat: Add experimental support for ManagedMediaSource
 (#1453)

Adds basic support for ManagedMediaSource. Must be enabled with the `useManagedMediaSource` VHS option.

Does not implement an alternate AirPlay source - this requires a more significant change, to add two source els. This means remote playback has to be disabled on the video el when using MMS.

Event listeners for advanced control are not yet implemented - `startstreaming`, `endstreaming`, `qualitychange`

+Use ManagedMediaSource when available. If both ManagedMediaSource and MediaSource are present, ManagedMediaSource would be used. This will only be effective if `ovrerideNative` is true, because currently the only browsers that implement ManagedMediaSource also have native support. Safari on iPhone 17.1 has ManagedMediaSource, as does Safari 17 on desktop and iPad.

Subject: [PATCH 381/399] fix: multi-period DASH VOD fixes (#1551)

* chore: clear previous dash media request timeout everytime we clear or update it

* chore: call fast-quality-switch only when we enable playlist from quality selector

* chore: add isPaused for dash playlist loader to mitigate duplicate playlist trigger for the main segment loader

* chore: fix fastQualityChange_ tests

* chore: add fast quality change debounce

* chore: add debounce tick to the tests

* chore: restart all loaders when we hit fix bad timeline change

* chore: update segment loader

* chore: update run-fast-quality-switch and fix bad timeline changes

* fix test

* chore: fix lint issues

Subject: [PATCH 386/399] feat: useNetworkInfo API by default + exclude audio
 only renditions when we have video renditions alongside (#1565)

* chore: filter audio-only playlists when we have playlists with video-only or muxed

* chore: set use network info api to true by default

* chore: simplify filter logic

* chore: use infinity exclude

* chore: default to true only if unset

* chore: fix tests

* feat: use default as true for networkInformation api

Subject: [PATCH 389/399] feat: Consider object-fit when selecting playlist by
 player size  (#1051)

* Make simple playlist selecor easier to extend

Refactor from positional parameters to a single `settings`
argument. This makes it clearer what each argument means in calls of
the function. Additional parameters can now be added without making
the argument list overly long.

Key names were chosen to match those of
`minRebufferMaxBandwidthSelector` to align the signatures.

* Make simpleSelector test easier to understand

Inline the passed bandwidth value instead of referencing the config
constant since the concrete value is needed to understand why the
expected playlist is chosen. Also if the config constant should ever
change the test will fail for no good reason.

* Consider object-fit when selecting playlist by player size

So far, when `limitRenditionByPlayerDimensions` is `true`,
`simpleSelector` tried to either find a rendition with a resolution
that matches the size of the player exactly or, if that does not
exist, a rendition with the smallest resolution that has either
greater width or greater height than the player. This makes sense
since by default the video will be scaled to fit inside the media
element. So every resolution that exceeds player size in at least one
dimension will be scaled down.

Most browsers support [1] customizing this scaling behavior via the
`object-fit` CSS property [2]. If it set to `cover`, the video will
instead be scaled up if video and player aspect ratio do not match.

The previous behavior caused renditions with low resolution to be
selected for players with small width (e.g. portrait phone aspect
ratio) even when videos were then scaled up to cover the whole player.

We therefore detect if `object-fit` is set to `cover` and instead
select the smallest rendition with a resolution that exceeds player
dimensions in both width and height.

[1] https://caniuse.com/?search=object-fit
[2] https://developer.mozilla.org/de/docs/Web/CSS/object-fit

* Add usePlayerObjectFit option

Only consider `object-fit` CSS property when selecting playlists based
on play size when `usePlayerObjectFit` option is `true` to make new
behavior an opt-in.

* chore: add object-fit option to the demo page

+
+### Features
+
+* Consider object-fit when selecting playlist by player size  ([#1051](https://github.com/videojs/http-streaming/issues/1051)) ([2c52076](https://github.com/videojs/http-streaming/commit/2c52076))
+* useNetworkInfo API by default + exclude audio only renditions when we have video renditions alongside ([#1565](https://github.com/videojs/http-streaming/issues/1565)) ([1289dd4](https://github.com/videojs/http-streaming/commit/1289dd4))
+
+### Bug Fixes
+
+* clamp seekable end to start instead of 0 ([#1564](https://github.com/videojs/http-streaming/issues/1564)) ([14ac65a](https://github.com/videojs/http-streaming/commit/14ac65a))
+* Ensure native segment metadata track has mode hidden ([#1550](https://github.com/videojs/http-streaming/issues/1550)) ([c1d3186](https://github.com/videojs/http-streaming/commit/c1d3186))
+
+### Chores
+
+* Updated link in readme leading to Decode Timestamp doc at w3.org ([#1562](https://github.com/videojs/http-streaming/issues/1562)) ([bc9e667](https://github.com/videojs/http-streaming/commit/bc9e667))

 playlist end for live streams (#1599)

For live streams with negative TIME-OFFSET in EXT-X-START, the offset
was incorrectly calculated from seekableEnd, which already has
liveEdgeDelay subtracted. This caused playback to start further behind
the live edge than intended.

Per HLS spec, negative TIME-OFFSET should be relative to the end of the
last Media Segment. This fix adds liveEdgeDelay back to seekableEnd
before applying the offset, making VHS behavior consistent with native
HLS implementations (e.g., Safari).

Example: With liveEdgeDelay=18 and TIME-OFFSET=-18:
- Before: startPoint = seekableEnd - 18 (36s behind actual live edge)
- After: startPoint = seekableEnd (18s behind, matching Safari)
