Summary of the bug:
Trying to apply vidstab{detect,transform} filters on a yuv444 encoded
input video fails with a pixel-format error.
This rather seems to be an incorrect assertion regarding the pixel formats
used in ffmpeg and/or the vid.stab library than a technical limitation
since commenting-out the check which fails seems to help and vidstab
appears to run fine on yuv444 input, but that is something that needs to
be validated.
How to reproduce:
{{{
# Create test video
% ffmpeg -t 10 -s 1280x720 -f rawvideo -pix_fmt rgb24 -r 30 -i /dev/zero
-pix_fmt yuv444p input.mkv
# Try to run vidstabdetect
% ffmpeg -i input.mkv -vf vidstabdetect -f null -
# Result:
[Parsed_vidstabdetect_0 @ 0x55a34dc71840] pixel-format error: wrong
bits/per/pixel, please report a BUG
# Try to run vidstabtransform
ffmpeg -i input.mkv -vf vidstabtransform -f null -
# Similar problem:
pixel-format error: bpp 1<>3 chroma_subsampl: w: 0<>0 h: 0<>0
ffmpeg version 3.3.4, Arch Linux
