This is a last call for aid... I am trying to cut sections from an MPEG2 generated by a KFir. By my understanding, the KFir uses bi-directional frame coding (IBP), as opposed to progressive frame coding, which makes cutting the files at clean boundaries very hard. I need to be able to cut a file into sections, (for burning to cd progressively), and those sections need to be sequential without loss.
I have written a program to almost completely dissect an MPEG2, (everything bar decoding the actual pictures), and output a section, but regardless of whether I set the group of pictures' header's 'broken_link' flag, I still get corrupt starts to the beginning of my sections. The closed_gop flag within the mpeg2 is set, meaning the fkir doesn't encode cleanly cuttable group_of_pictures. Does anyone know of a way I can "fix" the mpeg2 to have cleanly cuttable boundaries, or will I need to re-encode the whole file? _Any_ help on this subject would be great, I refuse to believe there is no way to do it :) Also, if anyone knows whether you can get the KFir to encode differently, shout me pls.
