For us, MPEG2 is just simply a codec, like every other codec around, so
we dont see any reason *NOT* to put it into MKV. We have found several
different occasions where it could be useful, and others may turn up we
havent thought of yet :
- MPEG editing : We are planning on making a general use video editor
tool based on MKV.That way any video format that can be transmuxed into
MKV could be edited, namely MPEG1/2/4, RealVideo, DV video, etc. could
be edited, and in combination with any supported audio format, and then
converted to any other formats afterwards. Not a very clean way you
might say, but definitely feasible. I dont know about Linux, but on
Windows there are no good and free MPEG video editors available, and i
dont know of any editor for RealVideo at all.
- Analog capturing with MPEG2 and FLAC audio : We only need a real time
MPEG2 DirectShow encoder filter ( based on libavcodec of course ), and
we could do this already, and with any DirectShow based capturing tool.
MPEG2 video gives excellent ration between bitrate and video quality, so
its a very good alternative to lossless or MJPEG capturing. And the FLAC
encoder consumes very little CPU compared to a MP2 or even AC3 encoder.
- Combination of MPEG2 video and any other audio format : After all, a
general use container should allow total freedom of the user, like AVI
does. We have test files ( musisc videos ) with MPEG2 video and Vorbis
audio, and they work great ;) ...
