I!
We're tryin to run this pipeline, in order to stream from firewire port: vale@valedipiu:~$ sudo gst-launch-0.10 dv1394src port=0 ! dvdec name=dv quality=3 { dv.audio ! queue ! audioconvert ! audio/x-raw-int,rate=22050,channels=2 ! queue ! vorbisenc quality=0.5 ! queue ! mux. } { dv.video ! queue ! videorate ! video/x-raw-yuv,framerate=25/2 ! videoscale ! video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! tee name=tscreen ! queue ! autovideosink tscreen. ! queue ! theoraenc quality=2 ! queue ! mux. } { oggmux name=mux ! shout2send ip=xxx.xx port=8000 mount=mountpoint.ogg password=xxxx streamname= description= genre= url= } BUT: WARNING: erroneous pipeline: could not link dv1394src0 to dv i'm actuallly using: gst-launch-0.10 version 0.10.18 GStreamer 0.10.18 https://launchpad.net/distros/ubuntu/+source/gstreamer0.10 on a intel coreduo: Linux valedipiu 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux modules ok: ohci1394 33584 1 dv1394 ieee1394 93752 4 raw1394,dv1394,sbp2,ohci1394 I'm linux-videomaker but not so experienced using gstreamer....and, for example...can't catch how to set correctly port and channel parameters.

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

What if one of those plugins does something stupid (by mistake) and tries to erase your hard drive ? Do you still want to run that pipeline as root ? That pipeline of yours is overkill and deprecated also. the '{' '}' style is from 0.8. You're using a dv decoder as if it was a demuxer (use dvdemux after your source).
