           Summary: Firewire-plugin dv1394src gives problems
           Product: GStreamer
           Version: 0.8.3
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal

I'd like to access arbitrary video-sources using gstreamer. I successfully got a
stable video image by doing "gst-launch dv1394src ! dvdec ! xvimagesink". I
wrote a plugin, which copies the received data into a chunk of shared-memory. I
actually got this plugin working.
I noted however, that when I try to read out the shared-memory, the pipeline
starts stuttering and usually breaks down after a couple of seconds. I've the
impression, that the firewire-library has problems, when another process is
taking away processor-time.
When I interrupt the pipeline, sometimes all processes get frozen and I only can
reset the computer.
Can anyone tell, what the problem is?
