Add support for ffprobe

[steelbrain]

Emby/jellyfin use it, we should support forwarding it too

good shout, - just set this up on my jellyfin, workin a TREAT! :)

so further investigation, transcoding is working Great!!

libary scanning is giving me trouble, im assuming linked to this ffprobe?

i've sat poking it in diffrence ways and setting up rewrites to /tmp/jellyfin where it puts all its genreated files and i just cant see to get ffmpeg to do something, no matter what folder i set it to, even a local one with rewrites, as it just stays empty

any ideas? :)

heres some log if it helps

Thats most likely. The logs indicate just the standard amount of aborted requests and finished connections. I think its the lack of ffprobe thats breaking library scanning.

Truth be told, I didnt even know anybody was using this :) so this is a welcome surprise

I’ll try and add ffprobe soon

[grantpeterwilliamson]

will keep my eye peeled like a bat ;)
