 FFmpeg/avformat fails to read files produced by newer Leitch/Harris
 servers (*.lxf). According to what I've learned, the file header and
 packet headers have grown a few bytes in the new version. The byte count
 for the headers have been updated, but I suspect that the lxf demuxer in
 avformat has these values hard coded. This is the output of FFmpeg:

 [lxf @ 020F9F40] checksum error
 [lxf @ 020F9F40] expected 120 B size header, got 0

 All the samples I have are very big (3GB+), so I can't send the files
 easily.
