[FFmpeg-devel] [PATCH 1/2] swscale/swscale_internal: interpret RGB paletted pixel formats as RGB

[Jan Ekström]

This makes isAnyRGB return true for AV_PIX_FMT_PAL8 which is currently
the only pixel format with this flag.

This lets us have a single query for formats where we need to force
range as only full range content is supported.
