    lavf/qtpalette: Treat 1-bit video as palettized · bd03ee11
    Mats Peterson authored
    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).
