33 * Pixel format. Notes:
|
|
nengel@2
|
34 *
|
|
nengel@2
|
35 * PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
|
|
nengel@2
|
36 * color is put together as:
|
|
nengel@2
|
37 * (A << 24) | (R << 16) | (G << 8) | B
|
|
nengel@2
|
38 * This is stored as BGRA on little-endian CPU architectures and ARGB on
|
|
nengel@2
|
39 * big-endian CPUs.
|
|
nengel@2
|
40 *
|
|
nengel@2
|
41 * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
|
|
nengel@2
|
42 * image data is stored in AVFrame.data[0]. The palette is transported in
|
|
nengel@2
|
43 * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
|
|
nengel@2
|
44 * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
|
|
nengel@2
|
45 * also endian-specific). Note also that the individual RGB palette
|
|
nengel@2
|
46 * components stored in AVFrame.data[1] should be in the range 0..255.
|
|
nengel@2
|
47 * This is important as many custom PAL8 video codecs that were designed
|
|
nengel@2
|
48 * to run on the IBM VGA graphics adapter use 6-bit palette components.
|
|
nengel@2
|
49 *
|
|
nengel@2
|
50 * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
|
|
nengel@2
|
51 * for pal8. This palette is filled in automatically by the function
|
|
nengel@2
|
52 * allocating the picture.
|
|
nengel@2
|
53 *
|
|
nengel@2
|
54 * Note, make sure that all newly added big endian formats have pix_fmt&1==1
|
|
nengel@2
|
55 * and that all newly added little endian formats have pix_fmt&1==0
|
|
nengel@2
|
56 * this allows simpler detection of big vs little endian.
