We are trying not to re-encode the video files as some users requested.
We are also negotiating with the developers about this.
At the moment, h264 codec + aac codec with .mp4 files are fine to play streaming directly but other file such as mkv, avi and other audio codes such as ac3 are need to be re-encoded.
AC3 is not able to play at chrome but ok with safari.
If you have anything to suggest, please send an email to firstname.lastname@example.org
