ffmpeg/libavfilter/vf_libplacebo.c
Niklas Haas c0b93c4f8b avfilter/vf_libplacebo: support all supported pixfmts 
This is done only to the inputs, not the outputs, because we always
output vulkan hwframes.

Doing so also requires keeping track of backing textures for non-hwdec
formats, but is otherwise a mostly straightforward change to the format
query function. Special care needs to be taken to avoid crashing on
older libplacebo due to AV_PIX_FMT_RGBF32LE et al.
