Hi, I´ve seen that there has been approach last month to implement AVC Intra mxf muxing. I tested the patches, but it didn´t work with any of my samples. Since there also has been discussions about the gpl restriction, I rewrote the patch. I had some basics, because I had written a working patch for myself some time ago, which was more of a hack and only worked with AVCI100 1080i50.
I hope this could be licenced to lgpl, because I got all labels from libmxf and libbmx and only used code snippets from avcodec/h264_parser.c
To keep h264 parsing simple and fast, I used the framesize for selecting the right Panasonic codec label. The framesize is fixed for Panasonic AVC Intra.
This patch only supports AVCI50/100. But in all flavours, i.e. with no SPS/PPS in header.
