Here you go..
[including dmesg information directly after modprobe uvcvideo];
For the sake of clarity I have sent the output as three different
attachments,
uvcvideo-modprobe-dmesg.txt: output from dmesg/kernel buffer after
'modprobe uvcvideo' (with options uvcvideo trace=0x40f)
mencoder-dmesg.txt: output from dmesg/kernel buffer after running mencoder
mencoder-output.txt: STDOUT from mencoder
I am not terribly familiar with mencoder as I have been doing most of my
testing with VLC, but the syntax I used for mencoder was
mencoder tv:// -tv
driver=v4l2:width=1280:height=720:device=/dev/video0:noaudio:fps=30:outfmt=mjpeg
-ovc lavc -lavcopts vcodec=mpeg4:vpass=1:autoaspect -o camera1.avi
I did notice that when using mencoder there were tons of 'duplicate frames'
messages which I am not sure if is related to this issue or not.
If you need any further details please let me know. Thanks again for your
assistance and commitment to this project :0
