|
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.
