[FFmpeg-devel] [PATCH] lavf/mxfdec.c: fix MXF essence body offsets when only 1 body partition

[Jason Livingston]

I was having trouble with some Avid OP-Atom MXF files that contain only 1 essence track and only 1 body partition with all the frames.  After the first call to av_read_frame(), it would return AVERROR_INVALIDDATA from mxf_absolute_bodysid_offset():
[mxf @ xxx] failed to find absolute offset of 100 in BodySID 1 - partial file?

The attached patch fixes this case which is probably pretty rare, but it shouldn't negatively affect anything else.

Unfortunately I can't distribute my sample file but I could probably construct one if necessary.

Thanks.
