Setting standard to PAL?

Hey, I tried:

v4l2-ctl -d /dev/video10 -s PAL-B -v width=704,height=576,pixelformat=MPEG; cat /dev/video10 > test.h264

But that gives me a 352x240 flickering image which is an NTSC resolution. It seems like the card is stuck in NTSC mode and I can't switch it to PAL.

Can you please provide a valid v4l2-ctl command to switch the card or input to PAL?

You have to specify the video_type when you load the module:

 

echo "options solo6x10 video_type=1" | sudo tee /etc/modprobe.d/bluecherry.conf

Thanks, that worked! - Getting pretty broken video though. I'm doing:

v4l2-ctl -d /dev/video10 -v width=704,height=576,pixelformat=MPEG && mencoder -nosound -ovc copy -frames 500 /dev/video10 -o test.avi

This is the result I'm getting:

Any ideas?

Are you using the latest driver from Github?

Yes I am, compiled earlier today. Just double checked, definitely latest:

root@demo1:~/solo6x10# git pull
Already up-to-date.

Running this on vanilla Ubuntu 11.04 Server
