  38.  * @note

  39.  * AV_PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA

  40.  * color is put together as:

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

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

  43.  * big-endian CPUs.

  44.  *

  45.  * @par

  46.  * When the pixel format is palettized RGB32 (AV_PIX_FMT_PAL8), the palettized

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

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

  49.  * formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is

  50.  * also endian-specific). Note also that the individual RGB32 palette

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

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

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

  54.  *

  55.  * @par

  56.  * For all the 8 bits per pixel formats, an RGB32 palette is in data[1] like

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

  58.  * allocating the picture.
