Hello everybody,

The last 7 days I have been trying very hard to get a live recording
system to work in several ways with mplayer and mencoder.

I have some killer issue, I have 2MP+ devices that are streaming trough
v4l2 and I want to be able to watch them and/or record the streams.

The most simple command I can think of for testing this:
$ mplayer -identify -benchmark -v tv:// -tv
driver=v4l2:device=/dev/video1:width=800:height=600:fps=25

The devices are capable to produce high resolution stream and fps, I
tested this with GUI tools like VLC and Guvciewer but I want/need to use
mplayer.

Please see the (watch0.log and versio0.log) for the details.

Mplayer renders the video but wont go higher then 640x480 with 15fps,
does somebody knows what is going wrong and how to fix this?

Thanks in advance for any help,

Best regards,

Jelle de Jong
