37  * Pixel format.
38  *
39  * @note
40  * AV_PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
41  * color is put together as:
42  * (A << 24) | (R << 16) | (G << 8) | B
43  * This is stored as BGRA on little-endian CPU architectures and ARGB on
44  * big-endian CPUs.
45  *
46  * @par
47  * When the pixel format is palettized RGB (AV_PIX_FMT_PAL8), the palettized
48  * image data is stored in AVFrame.data[0]. The palette is transported in
49  * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
50  * formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is
51  * also endian-specific). Note also that the individual RGB palette
52  * components stored in AVFrame.data[1] should be in the range 0..255.
53  * This is important as many custom PAL8 video codecs that were designed
54  * to run on the IBM VGA graphics adapter use 6-bit palette components.
55  *
56  * @par
57  * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
58  * for pal8. This palette is filled in automatically by the function
59  * allocating the picture.
60  *
61  * @note
62  * Make sure that all newly added big-endian formats have (pix_fmt & 1) == 1
63  * and that all newly added little-endian formats have (pix_fmt & 1) == 0.
64  * This allows simpler detection of big vs little-endian.
