I finally finished this code and it seems to be working fine. I am going to
test in a second on a MPEG1 clip out of curiosity. But reading mpeg2 seems
fine. I just need to implant this code in someone's muxer :) Right now it
tells a lot of details about the frames such as whether it's progressive,
interlaced, pulldown-on-playback etc.
The problem is how to mux this. I think the GOP header should go with the
I-frame in a single block. Also, there are repeated sequence headers before
most GOPs. We can stick these with the I frame as well. The decoders
have no problem with this. The frames are in coding order. And the problem
comes here: Some frames in MPEG2 video actually decode to 2 frames on
playback to produce a 3:2 pulldown. I can detect these frames with my code
but how do we timestamp them. I will be on IRC tomorrow (Thursday) at aroun
9am my time. I think I am GMT-7 but not sure about that ;)
/me goes to check that mpeg1 stream.
IT WORKS!!!! W00T!!!! MPEG1 is packetized too :O
