-/**
- * Pixel format. Notes:
- *
- * PIX_FMT_RGB32 is handled in an endian-specific manner. An 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], 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.
- *
- * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
- * for pal8. This palette is filled in automatically by the function
- * allocating the picture.
- *
- * Note, make sure that all newly added big endian formats have pix_fmt&1==1
- *       and that all newly added little endian formats have pix_fmt&1==0
- *       this allows simpler detection of big vs little endian.
