/**
* Pixel format . Notes :
*
* PIX_FMT_RGB32 is handled in an endian - specific manner . A RGBA
* color is put together as :
* ( A < < 24 ) | ( R < < 16 ) | ( G < < 8 ) | B
* This is stored as BGRA on little endian CPU architectures and ARGB on
* big endian CPUs .
*
* When the pixel format is palettized RGB ( PIX_FMT_PAL8 ) , the palettized
* image data is stored in AVFrame . data [ 0 ] . The palette is transported in
* AVFrame . data [ 1 ] and , is 1024 bytes long ( 256 4 - byte entries ) and is
* formatted the same as in PIX_FMT_RGB32 described above ( i . e . , it is
* also endian - specific ) . Note also that the individual RGB palette
* components stored in AVFrame . data [ 1 ] should be in the range 0. .255 .
* This is important as many custom PAL8 video codecs that were designed
* to run on the IBM VGA graphics adapter use 6 - bit palette components .
