Hello,

I want to read vbi lines of the frames of analog TV. I want to use VBI data in my programm.

I tune to the channel.
/opt/bin/mediaclient -m ATV -f 223250000 -d /dev/video0 -v SECAM-K

Then I can save frames from TV - it works OK. For example:
mplayer tv:// -tv driver=v4l2:device=/dev/video0:normid=7 -frames 20 -vo jpeg

But when I'm trying to get VBI lines, I've got only green filled pictures. What I do wrong?
