jozee@2680 63 * Pixel format. Notes:
jozee@2680 64 *
jozee@2680 65 * PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
jozee@2680 66 * color is put together as:
jozee@2680 67 * (A << 24) | (R << 16) | (G << 8) | B
jozee@2680 68 * This is stored as BGRA on little-endian CPU architectures and ARGB on
jozee@2680 69 * big-endian CPUs.
jozee@2680 70 *
jozee@2680 71 * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
jozee@2680 72 * image data is stored in AVFrame.data[0]. The palette is transported in
jozee@2680 73 * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
jozee@2680 74 * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
jozee@2680 75 * also endian-specific). Note also that the individual RGB palette
jozee@2680 76 * components stored in AVFrame.data[1] should be in the range 0..255.
jozee@2680 77 * This is important as many custom PAL8 video codecs that were designed
jozee@2680 78 * to run on the IBM VGA graphics adapter use 6-bit palette components.
jozee@2680 79 *
jozee@2680 80 * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
jozee@2680 81 * for pal8. This palette is filled in automatically by the function
jozee@2680 82 * allocating the picture.
