+ * 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.
