2. You say that demuxers might not set the pixel format. This is on
the muxing side though. Isn't the pixel format always set when
muxing?
theres no guratee that its set for the muxer
there could be demuxer -> muxer with no decoder as well but thats
not the only case, it could just be that the application doesnt
set it, its not written in the API that the application has to set it
Perhaps so, but for raw uncompressed video, as long as you only have one
collective 'raw ' fourcc for it, it's crucial to know the pixel format,
whether it's RGB, grayscale or YUV for example.
