Invalid Argument

[Iñaki <gcypher@xxxxxxxx>]

Hi

   I'm trying to port an v4l application to v4l2 but in first calls my 
application crash with:

   "Invalid argument" when i use :

    if ( ioctl(grab_fd,VIDIOC_G_INPUT,&index) == -1)
   {
     perror("VIDIOC_G_INPUT error!!!");
     exit (-1);
   }

   and in others calls i obtain the same. I think it must be because of 
the device video0 is wrong (but i can open it without problems).

   I've installed kernel 2.4.20 patched with  patch-2.4.20-kraxel.gz 
<http://bytesex.org/patches/2.4/patch-2.4.20-kraxel.gz> and bttv 0.9.9.

   Using v4l2 is this right?:

   dev]$ ll vide*
   lr-xr-xr-x    1 root     root           10 mar 27 10:01 video -> 
v4l/video0
   lr-xr-xr-x    1 root     root           10 mar 27 10:01 video0 -> 
v4l/video0

Thanks
