Summary0015950: Encoder: Optimization of Encoding processes to avoid non needed conversions
DescriptionIn many new cases there is no need for full re encode but only remux (container change) is needed or partial re encode is needed.

Remux:
MKV -> MP4 = ffmpeg -i 1.mkv -vcodec copy -acodec copy 1.mp4

Partial encode:
MKV(AC3) = ffmpeg -i 1.mkv -vcodec copy -c:a libmp3lame -b:a 320k 1.mp4

Added relations to 0015949 as Video transcoding uses High CPU as MM do not take advantage of Hardware encoding.

I wouldn't go into this in MM5, but we could implement such things in MMS, where it makes more sense.

Can you please revise if we can use similar process to our current encoders in order to save us time on DLNA Playback or sync to devices that do not support MKV container?

Otherwise just revert resolution.
