[FFmpeg-devel] [PATCH v2 0/2] avfilter/vf_thumbnail: support more formats

[Niklas Haas]

Changes since v1:
- merge the 16-bit and 8-bit cases to reduce a bit of code duplication
- add the support for grayscale formats as well
- switch to query_func2 instead of hard-coding the format list

I'm not sure I like the complicated logic inside query_func2 now, it feels
like it hard-codes just as many assumptions as a static list.
