Hi all -
I'm playing with video(1), reading from my webcam and have noticed
after working for a short while (20 - 60 seconds), the video process
will die, and writes the following error: "video: ioctl VIDIOC_DQBUF:
Invalid argument"
$ date ; video -v -v -v -v -v ; date

What's odd is that it appears to be related to displaying the output
via Xv(3) (the default for video(1)). If I write to
stdout/pipe-to-/dev/null, it crashes _less_ often...but eventually
does:
$ date ; video -v -v -v -v -v -o - > /dev/null; date
