Ok. Since I didn't have much luck with the patch against the current Ubuntu package I've grabbed the latest version from Subversion and built that (Using the cmake/make combination). Unfortunately while programs no longer terminate with the 'VIDIOC_DQBUF error 5, Input/output error' they'll quickly get stuck in a EAGAIN loop (usually after 2 or 3 EIO errors). Again it seems to be very closely correlated with the 'bttv0: timeout' in the kernel log, though I can't seem to reproduce this error with any other program that uses v4l2.
I've opened up another bug on the OpenCV bugtracker and hopefully we might be able to work out what on earth is going on. -- bttv driver dies with VIDIOC_DQBUF error https://bugs.launchpad.net/bugs/260251 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
