metadata extraction from media files

[viliman]

rameplayer should be able to extract the metadata such as length of clip, title, chapter info from media files. E.g. using ffmpeg.

https://www.ffmpeg.org/ffmpeg-formats.html#Metadata-1

This then should be read by the web UI

ffprope might work even better and it can write the output in JSON, XML..
