I'm reading out the supported pixel formats for various codecs
through GetComponentPublicResource
I see ARGB or BGRA is never listed. I know every codec supports
ARGB input, but what about BGRA - will every codec be able to
process that too?
Almost all codecs support ARGB. However, if you're looking for the
four-character code 'ARGB', you won't find it. For historical reasons
dating back to QuickDraw, ARGB, or k32ARGBPixelFormat, has a value of
32, rather than a four-character code.
BGRA, or k32BGRAPixelFormat, is generally only supported on Windows.
