There is Xv query function which returns supported formats by Xv.
(it could support more than yuv420p/I420 like BGRA)

See xv code that is in mpv/mplayer... (This is second time I mention this)

For testing you just set -pix_fmt that is equivalent of Xv one and
swscale/ffmpeg do
conversion for you - no need for special files.
