This is a silent API break. You changed behavior of a function in such a way
that functioning code no longer works.

See, for example: https://github.com/FFMS/ffms2/issues/256

The related bit of code: https://github.com/FFMS/ffms2/blob/7c2e08109d6097d5a644722ca7cfafa002203457/src/core/videosource.cpp#L159-L162

(Why the heck GRAY8 has a palette at all is also a bit WTF,
but unrelated to my point here.)
