[Matroska-general] For all savvy encoders

For the multiangle feature we'll need a few restrictions on the streams. 
The most important one is that we should only switch angles on a 
keyframe. I think that's how it's done on DVDs...

If you only rip your DVDs to the original MPEG2 in MKV (still waiting 
for support in mtx ;) there won't be any pb. But if you encode that 
MPEG2 video stream to something else, you can't enforce the main video 
to have a keyframe at each change/gap in other angles...

So my question is : is there any way to force keyframes at known 
locations when encoding in the few popular codecs (DivX, XviD, RV9) ? If 
not we probably won't create such an application. So the other option 
would be to encode all parts of a movie separately and then join the 
final data. Do you think it's possible for these same codecs ? Just 
keeping the codec informations of the first encoded file...
