[gst-devel] problems with firewire port

Hi,

  Have you tried not specifying the port ? Unless you have several
cameras on your firewire port you don't need to specify it.

  And a simpler way to test if you're getting anything from that source
is to try this:
  gst-launch-0.10 dv1394src ! fakesink

  If that pipeline goes to playing, you're all set.

P.S. 'sudo gst-launch-0.10' <== BAD BAD BAD ! Change your user
privileges to be able to access that device as non-root.
