Re: how to make qbuf




Hello,

I suppose you can have more comments if you post on the current v4l2 list.
I mean, linux-media@xxxxxxxxxxxxxxx
And also you can find latest v4l2 works at linuxtv.org the leading
community of v4l2.
I think I can help you if you give me more specific question about
what makes you confused.
Cheers,
