if i relaunch mplayer dont work, but a few minutes later it works again for
another 5 seconds and then i need to restart the camera.

I cannot see the fps when the camera freezes, but i started the operation
with green fps (no autoexposure, 30 milis shutter)

The scene is static, this only affects to the final compresion, right?
