Because of Reimar Doeffinger comment in thread  "[PATCH] Mobotix .mxg 
demixer and MxPEG decoder basic    implementation" :

"Splitting into individual frames really does not belong into the demuxer,
it should be done in a parser.
A demuxer should only do things like splitting audio and video,
and if available process pts, dts, metadata, keyframe flags etc.
This is doubly true for JPEG where I think there are still issues
with interlaced JPEG and this could not benefit from
any fixes to that."



I need a final decision about this. If splitting into individual frames 
can be done in demuxer - I will do it there. Otherwise, I will leave it 
in parser.
