This commit for qtpalette.c and qtpalette.h adds 1-bit video to the "palettized video" category, since if the video sample description contains a palette, the two colors in the palette can be any color, not necessarily black & white. Unfortunately, I've noticed that the qtrle (QuickTime Animation) decoder blindly assumes that 1-bit video is black & white. I don't have enough knowledge about the decoder to fix this, though. Below is a link to a sample 1-bit QuickTime Animation clip of a rotating earth that uses blueish colors, and they will be correctly rendered in QuickTime, but not in FFmpeg (which will use black & white). https://drive.google.com/open?id=0B3_pEBoLs0faUlItWm9KaGJSTEE Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
