118
 * Pixel format. Notes: 
119
 *
120
 * PIX_FMT_RGBA32 is handled in an endian-specific manner. A RGBA
121
 * color is put together as:
122
 *  (A << 24) | (R << 16) | (G << 8) | B
123
 * This is stored as BGRA on little endian CPU architectures and ARGB on
124
 * big endian CPUs.
125
 *
126
 * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
127
 * image data is stored in AVFrame.data[0]. The palette is transported in
128
 * AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is
129
 * formatted the same as in PIX_FMT_RGBA32 described above (i.e., it is
130
 * also endian-specific).
