[FFmpeg-devel] [PATCH] lavfi/vf_libplacebo: test for renderable pixel formats

[Niklas Haas]

From: Niklas Haas <git@haasn.dev>

Requires a new upstream function to test not for *import* support on a
given output pixel format, but also whether we can render to it.

Fixes: https://github.com/haasn/libplacebo/issues/173
