For the sake of information, I checked and "ffmpeg ... -f sdl -" does 
play the video as fast as the computer can,  and without audio.
So this is similar to mplayer's -benchmark mode,  however the video 
latency with "ffmpeg ... -f sdl -" is still even worse than mplayer's 
-benchmark mode, which isn't very good to begin with as far as realtime 
low-delay video.

I wonder if I'm losing time in the TCP/HTTP buffers or process or maybe 
it has to do with tcp window size.

Thanks again,
