It works with tvtime by just giving /dev/video0 as the command line parameter. BTW, I am only interested in capturing the composite video-in signal. However, I do not know how to capture it with totem. Giving /dev/video0 as the parameter does not help. I have v4l2 plugin installed and the gstreamer-properties shows my card and it gives output from an untuned tv channel. But how do I construct a pipeline for capturing composite video-in and is it possible to watch it through totem using this pipeline? </blockquote><div> Gstreamer lacks an easy or reliable way to setup the input on capture cards. You can get some info about the "tuner interface" here: <a href="http://gstreamer-devel.966125.n4.nabble.com/Select-input-on-a-v4l2-device-td3081723.html">http://gstreamer-devel.966125.n4.nabble.com/Select-input-on-a-v4l2-device-td3081723.html</a> There is a link to some sample code, but I've never found it to be reliable -- after a reboot the gstreamer code often fails to work the first time, but if I quit the program and rerun it, it then seems to work OK until the next reboot. The TVtime application is the most reliable program I've found with regards to changing video inputs and norms (PAL vs. NTSC) across the eight brands of capture hardware I have access too. I'll eventually pull its v4l2 selection code out and use it in my application instead of the "interfeces" kludge of gstreamer. If you set your cards norm and select the input you want with TVtime or v4l2-ctr (its of the ivtv-utils package) then this should work: v4l2src device=/dev/video0 ! xvimagesink As far as I can tell Totem is only setup for playing file inputs. </div>
