I've tried with latest version of the Mplayre from svn and have a
green window and the logs below, can you explain this? Is it a driver'
problem or is it a userspace software' problem? Why Mplayer use
Current input=1? In the cmd there is an input 0.

And with the LD_PRELOAD libv4l I have the same result.

I can change frame format in the driver, what frame formats mplayer
support? I can chose yuv422, yuv420, raw, jpeg

./mplayer tv:// -tv
driver=v4l2:width=640:height=480:fps=25:device=/dev/video0:input=0 -vo
