    1.36 + * Pixel format. Notes:
    1.37 + *
    1.38 + * PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
    1.39 + * color is put together as:
    1.40 + *  (A << 24) | (R << 16) | (G << 8) | B
    1.41 + * This is stored as BGRA on little-endian CPU architectures and ARGB on
    1.42 + * big-endian CPUs.
    1.43 + *
    1.44 + * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
    1.45 + * image data is stored in AVFrame.data[0]. The palette is transported in
    1.46 + * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
    1.47 + * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
    1.48 + * also endian-specific). Note also that the individual RGB palette
    1.49 + * components stored in AVFrame.data[1] should be in the range 0..255.
    1.50 + * This is important as many custom PAL8 video codecs that were designed
    1.51 + * to run on the IBM VGA graphics adapter use 6-bit palette components.
    1.52 + *
    1.53 + * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
    1.54 + * for pal8. This palette is filled in automatically by the function
    1.55 + * allocating the picture.
    1.56 + *
    1.57 + * Note, make sure that all newly added big endian formats have pix_fmt&1==1
    1.58 + *       and that all newly added little endian formats have pix_fmt&1==0
    1.59 + *       this allows simpler detection of big vs little endian.
