decklinksink plugin does not work with filesrc, only with videotestsrc

[João Paulo Pizani Flor]

I'm using Ubuntu 11.10, with gstreamer-plugins-bad version 0.10.22-2ubuntu4.

My goal is to be able to simply output video from GStreamer to a decklink card by Black Magic Devices.

I thought the following would Just Work®: gst-launch-0.10 playbin uri=file:///home/joaopizani/test.mp4 video-sink=decklinksink

Instead, gst-launch reported the following error:
"ERROR: from element /GstPlayBin:playbin0: Internal GStreamer error: pad problem. Please file a bug at http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.
Additional debug info:
gstplaybin.c(928): gen_video_element (): /GstPlayBin:playbin0:
Failed to configure the video sink."...

All the drivers and APIs from Black Magic Design are installed and my system is configured correctly. As a proof, the following works just fine: gst-launch-0.10 videotestsrc ! decklinksink

Any ideas what might be going wrong?

Just another question, a "point of order": I am not sure wheter this is a bug related to Ubuntu packaging or upstream. Therefore, should I also file the bug with the gstreamer guys or will it be done automatically by Launchpad?

I don't think this bug is relevant anymore. I already found out that the problem was me :) When I added a scaling/conversion step to the pipeline, then decklinksink was able to handle to videostream. Sorry, guys.
