[FFmpeg-devel] [PATCH 1/2] pixfmt: add AV_PIX_FMT_GBRAP32

[FFmpeg-devel] [PATCH 1/2] pixfmt: add AV_PIX_FMT_GBRAP32

[Lynne]

This commit adds a 32-bit *integer* planar RGBA format.
Vulkan FFv1 decoding is best performed on separate planes, rather than
packed RGBA (i.e. RGBA128), hence this is useful as an intermediate format.
