/**
52
 * Pixel format. Notes:
53
 *
54
 * PIX_FMT_RGB32 is handled in an endian-specific manner. A RGBA
55
 * color is put together as:
56
 *  (A << 24) | (R << 16) | (G << 8) | B
57
 * This is stored as BGRA on little endian CPU architectures and ARGB on
58
 * big endian CPUs.
59
 *
60
 * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
61
 * image data is stored in AVFrame.data[0]. The palette is transported in
62
 * AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is
63
 * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
64
 * also endian-specific). Note also that the individual RGB palette
65
 * components stored in AVFrame.data[1] should be in the range 0..255.
66
 * This is important as many custom PAL8 video codecs that were designed
67
 * to run on the IBM VGA graphics adapter use 6-bit palette components.
