Sorry, please find attached the unified diff.
How i produced the assertion ?
It happens frequently when encoding snow video with low resolution.
There is more info in the tracker, along with some sample media.
ffmpeg -i sample_media -vcodec snow -strict -2 -an -s 74x68 -f nut
The scaling is not part of the problem, encoding png's already this size can
auto trigger the assertion.
