As I've found - mplayer knows much more video image formats:

file main/libvo2/img_format.h
/* RGB/BGR Formats */

#define IMGFMT_RGB_MASK 0xFFFFFF00
#define IMGFMT_RGB (('R'<<24)|('G'<<16)|('B'<<8))
#define IMGFMT_RGB8  (IMGFMT_RGB|8)
#define IMGFMT_RGB15 (IMGFMT_RGB|15)
#define IMGFMT_RGB16 (IMGFMT_RGB|16)
#define IMGFMT_RGB24 (IMGFMT_RGB|24)
#define IMGFMT_RGB32 (IMGFMT_RGB|32)

#define IMGFMT_BGR_MASK 0xFFFFFF00
#define IMGFMT_BGR (('B'<<24)|('G'<<16)|('R'<<8))
#define IMGFMT_BGR8 (IMGFMT_BGR|8)
#define IMGFMT_BGR15 (IMGFMT_BGR|15)
#define IMGFMT_BGR16 (IMGFMT_BGR|16)

Other things look - ok.
