The option "-f h264" specifies a raw video output without a container. Not every
video player is able or willing to play such a file. MPV, gxine and mplayer do
play it, VLC does not (at least not by default).
You could try "-f flv" and see if your player accepts it. FLV is often used in
streaming and may be more suitable for your needs.
