Hello, after a successful Core Server installation on a dedicated server, I'm trying to install the Capture Agent 1.3.1 on a PC running Ubuntu 10.10 64 bits, but I can't configure properly nor the Epiphan VGA2USB Card neither the BlackMagicDesign Intensity Pro PCI-Express card.
Problem1 -> VGA2USB: I'm able to capture the vga output using mencoder: mencoder -oac lavc -ovc lavc -lavcopts vcodec=mpeg4:keyint=100:vbitrate=8000:vhq -noaspect -o /home/client/test3.avi -tv noaudio:driver=v4l:outfmt=bgr24:device=/dev/video0 tv:// However, from http://localhost:8080/capture I can start/stop capturing, but the file Epiphan_VGA2USB.mpg is empty (0 Bytes). The configuration in /opt/matterhorn/felix/conf/services/org.opencastproject.capture.impl.ConfigurationManager.properties: [...] capture.device.Epiphan_VGA2USB.src=/dev/video0 capture.device.Epiphan_VGA2USB.outputfile=Epiphan_VGA2USB.mpg capture.device.Epiphan_VGA2USB.flavor=presenter/source capture.device.Epiphan_VGA2USB.buffer.bytes=536870912 capture.device.Epiphan_VGA2USB.type=EPIPHAN_VGA2USB capture.device.Epiphan_VGA2USB.confidence.interval=10 [...] Problem2 -> Intensity PRO: >From my point, the card is properly detected: root@client-desktop:/opt/matterhorn# dmesg | grep blackmagic [ 11.866896] blackmagic: module license 'Proprietary' taints kernel.

Now I have an updated version of gstreamer-plugins-bad: 0.10.22, that includes decklinksrc. However, I can run gst-inspect decklinksrc but I suspect that the output is not the desired: Factory Details: Long name: Decklink source Class: Source/Video Description: DeckLink Source Author(s): David Schleef <[email protected]> Rank: none (0) Plugin Details: Name: decklink Description: Blackmagic Decklink plugin Filename: /usr/lib/gstreamer-0.10/libgstdecklink.so Version: 0.10.22 License: LGPL Source module: gst-plugins-bad Source release date: 2011-05-10 Binary package: GStreamer Bad Plug-ins Origin URL: https://launchpad.net/distros/ubuntu/+source/gst-plugins-bad0.10 [...] Element Properties: name : The name of the object flags: readable, writable String. Default: null Current: "decklinksrc0" I think that is missing the final part where is defined the "input" and the "input-mode" and without that I can't execute this: gst-launch -v -m decklinksrc input=HDMI input-mode=4 ! queue ! ffmpegcolorspace ! ffenc_mpeg2video ! mpegtsmux ! filesink location=/tmp/test.mpg WARNING: erroneous pipeline: no property "input" in element "decklinksrc0" Thank you and sorry for the huge extension :) Oriol.
