384bdace 33 * Pixel format.

384bdace 35 * @note

SS
36 * PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
37 * color is put together as:
38 * (A << 24) | (R << 16) | (G << 8) | B
39 * This is stored as BGRA on little-endian CPU architectures and ARGB on
40 * big-endian CPUs.
41 *
384bdace 42 * @par
04331dea
SS
43 * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
44 * image data is stored in AVFrame.data[0]. The palette is transported in
45 * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
46 * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
47 * also endian-specific). Note also that the individual RGB palette
48 * components stored in AVFrame.data[1] should be in the range 0..255.
49 * This is important as many custom PAL8 video codecs that were designed
50 * to run on the IBM VGA graphics adapter use 6-bit palette components.
51 *
384bdace 52 * @par
04331dea
SS
53 * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
54 * for pal8. This palette is filled in automatically by the function
55 * allocating the picture.
56 *
384bdace
LB
57 * @note
58 * make sure that all newly added big endian formats have pix_fmt&1==1
59 * and that all newly added little endian formats have pix_fmt&1==0
60 * this allows simpler detection of big vs little endian.
