I'm having a heck of a time getting v4l2 running on a server. Recently
I tried 2.4.21 patched cleanly for v4l2 on a RH8 box using the infamous
WinTV Go card. With any version of bttv 0.9 it loaded and attached
itself to /dev/video31 which did not exist.
I compiled 2.4.22 with patches and I can now get bttv on /dev/video0
(with no changes in modules.conf from 2.4.21)
but... xawtv works fine xawtv -hwscan reports it is only v4l. Tried
the old sample apps (vctrl, xcaptest) and it bails on QUERYCAP hinting
that it can't find the v4l2 in bttv either. (they do compile cleanly on
the patched 2.4.22 videodev.h so it is finding the v4l2 libraries) I
tried bttv 0.9.5 - 0.9.11, all compile great but no v4l2.
I'm really climbing a wall here, I have to get this done for a project.
The software was written on a RH 7.2 box with the old v4l2 stuff, and
I need to bring the server up to a recent version for security and sanity.
Thank you to whoever has pity on me!
