[Niklas Haas via ffmpeg-devel <ffmpeg-devel@ffmpeg.org>]

PR #20849 opened by Niklas Haas (haasn)
URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20849
Patch URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20849.patch

The MSB YUV formats were added, but the gray formats were not. Seems to have
been an oversight.
