Comment (by Francesco Bucciantini):
To put it down even further, the problem with 7.x and master is when the
matrix, primaries and transfer are changing, in fact if the file is
trimmed to isolate the parts where those stay the same, then FFMpeg has no
problem with them.
Obviously in the section in which they're all populated it's gonna say:
Stream #0:0: Video: wrapped_avframe, yuv422p(tv, bt709, top coded first
(swapped)), 1920x1080 [SAR 1:1 DAR 16:9], q=2-31, 200 kb/s, 25 fps, 25 tbn
while in the one in which they're not populated it's gonna say:
Stream #0:0: Video: mpeg2video (4:2:2), yuv422p(tv,
unknown/reserved/reserved, top first), 1920x1080 [SAR 1:1 DAR 16:9], 50000
kb/s, 25 fps, 25 tbr, 25 tbn
but it won't crash, however if we don't trim and we let it analyze a file
with a transition, then we get the aforementioned crash:
