+ * Pixel format. Notes:
+ *
+ * PIX_FMT_RGBA32 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_RGBA32 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.
