But that seems perfectly OK... its not ok, if only 2bpp are used and its possible to store just 2bpp then thats what should be done by default. Same for 4bpp that could be done with PAL8 and using its palette or using some *_bits_per_pixel variable or a seperate PAL4/PAL2 many possibilities and likely even more but the end result should be efficient storage so that encoders/muxers supporting 2/4 bpp should use these when possible and by default without the user needing to know all the details [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Everything should be made as simple as possible, but not simpler. -- Albert Einstein
