63 * Pixel format. Notes:

64 *

65 * PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA

66 * color is put together as:

67 * (A << 24) | (R << 16) | (G << 8) | B

68 * This is stored as BGRA on little-endian CPU architectures and ARGB on

69 * big-endian CPUs.

70 *

71 * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized

72 * image data is stored in AVFrame.data[0]. The palette is transported in

73 * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is

74 * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is

75 * also endian-specific). Note also that the individual RGB palette

76 * components stored in AVFrame.data[1] should be in the range 0..255.

77 * This is important as many custom PAL8 video codecs that were designed

78 * to run on the IBM VGA graphics adapter use 6-bit palette components.

79 *

80 * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like

81 * for pal8. This palette is filled in automatically by the function

82 * allocating the picture.
