Summary of the bug: ffmpeg and ffplay crash with -vf unsharp=6
How to reproduce:
{{{
% ffmpeg -i test.jpg -vf unsharp=6 test.png
% ffplay -vf unsharp=6 test.jpg
ffmpeg version git-2019-11-30-e5db2e9
built on Sun 01 Dec 2019 01:08:08 AM MST
}}}
I was somewhat blindly playing with the unsharp filter and I found a
reproducible crash. I rebuilt my SDL with debug symbols but there might be
some stuff missing with ffmpeg_g.
I'll attach gdb logs of the crash with ffplay_g and ffmpeg_g. I'd prefer
not to attach the image, but here's some ffprobe output:
Input #0, image2, from '/home/tod/Pictures/bz5057-01-600x891.jpg':
Duration: 00:00:00.04, start: 0.000000, bitrate: 73946 kb/s
Stream #0:0: Video: mjpeg (Baseline), yuvj420p(pc,
bt470bg/unknown/unknown), 600x891 [SAR 1:1 DAR 200:297], 25 tbr, 25 tbn,
25 tbc
I can test whatever you like.
Thanks,
Tod
