Hello,
since I started recently to develop a v4l2 driver, I may suggest you to
read some tutorials like
http://www.linuxtv.org/downloads/video4linux/API/V4L2_API/spec-single/v4l2.html
that explains clearly how the things shall be made.
You will find chapters about Raw VBI and Sliced VBI that I did not read
yet, but I should...
Hope this starts to help you.
Cheers,
Thierry

Hi,
I am new to v4l2 driver. I want to write a driver which does both video
capture and VBI capture. So, I have few questions in relation to this:
1. Would it be better to have separate devices for video and VBI in the same
driver? Or should VBI capture be handled in the same video capture device.
If yes then how can that be done?
2. If I also need to capture the horizontal ancillary data again will I need
separate device for that or else how to handle that using v4l2.
Any suggestions or comments would be a great help.
Thanks,
Parul
