[Live-devel] MPEG-4 in MPEG2-PS

[Scott Hays]

Thanks, Leon.  I've gotten it to work more or less myself after  
hacking the MPEG-2 Program Stream demuxer and parser classes.  I'm  
not sure I would have had to do any hacking if the MPEG-4 data inside  
had included the VS and VO headers.  Anyway, after all that work, we  
decided that we want to remultiplex the MPEG-2 PS stream to an MP4  
file as it comes from the encoder anyway because MPEG-2 Program  
Streams don't seem to be very good for anything other than straight  
playing (they're not really good for efficient "trick-mode" playing).

Thanks for the response!
