Comment 1 Snark 2006-10-28 12:13:40 UTC

It looks like it crashed while detecting your video devices... are you sure your driver isn't experimental/buggy ?

Comment 3 Damien Sandras 2006-10-30 08:31:21 UTC

It crashes in V4LNames::BuildUserFriendly ().

The code is the following :
PString V4LNames::BuildUserFriendly(PString devname)
{
  PString Result;

  int fd = ::open((const char *)devname, O_RDONLY);
  if(fd < 0) {
    return devname;
  }

  struct video_capability videocap;
  if (::ioctl(fd, VIDIOCGCAP, &videocap) < 0)  {
      ::close(fd);
      return devname;
    }

  ::close(fd);
  PString ufname(videocap.name);

  return ufname;
}


I see nothing there that could trigger a crash except a buggy video driver.


Can one of you provide a backtrace with debug symbols?

Thanks

Comment 4 rpage_is_king 2006-11-01 23:58:34 UTC

The driver (gspcav1-20060925) is relatively new, so it may be buggy. The camera worked in the "Camorama" application, but this was the first time I've attempted to use it with Ekiga.

Comment 5 Snark 2006-11-05 08:26:28 UTC

I would say : report the bug to the driver authors. We pasted the crashing code here, they should be able to reproduce.
