From debugging the issue this seems to happen only when video resolution
is not divisible by 32.
How to reproduce:
{{{
ffmpeg.exe -ss 00:00:00.50 -i test.avi -vframes 1 -pix_fmt rgba test.png

This may be same report as #8871, but in this case8 px on left side are
corrupted.
This issue happens in Blender, but there every line of output is corrupted
like this.
