30/**
31 * Pixel format. Notes:
32 *
33 * PIX_FMT_RGBA32 is handled in an endian-specific manner. A RGBA
34 * color is put together as:
35 * (A << 24) | (R << 16) | (G << 8) | B
36 * This is stored as BGRA on little endian CPU architectures and ARGB on
37 * big endian CPUs.
38 *
39 * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
40 * image data is stored in AVFrame.data[0]. The palette is transported in
41 * AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is
42 * formatted the same as in PIX_FMT_RGBA32 described above (i.e., it is
43 * also endian-specific). Note also that the individual RGB palette
44 * components stored in AVFrame.data[1] should be in the range 0..255.
45 * This is important as many custom PAL8 video codecs that were designed
46 * to run on the IBM VGA graphics adapter use 6-bit palette components.
