    1.66 + * Pixel format. Notes:
    1.67 + *
    1.68 + * PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
    1.69 + * color is put together as:
    1.70 + *  (A << 24) | (R << 16) | (G << 8) | B
    1.71 + * This is stored as BGRA on little-endian CPU architectures and ARGB on
    1.72 + * big-endian CPUs.
    1.73 + *
    1.74 + * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
    1.75 + * image data is stored in AVFrame.data[0]. The palette is transported in
    1.76 + * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
    1.77 + * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
    1.78 + * also endian-specific). Note also that the individual RGB palette
    1.79 + * components stored in AVFrame.data[1] should be in the range 0..255.
    1.80 + * This is important as many custom PAL8 video codecs that were designed
    1.81 + * to run on the IBM VGA graphics adapter use 6-bit palette components.
    1.82 + *
    1.83 + * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
    1.84 + * for pal8. This palette is filled in automatically by the function
    1.85 + * allocating the picture.
