Sorry for the delay, more progress now: We installed everything from scratch: new Ubuntu, new MH 1.1, etc. We can successfully install the VGA2PCIe drivers. We can successfully watch the frame grabber video with gst-launch -e v4lsrc device=/dev/video0 ! queue ! autovideosink The config part of the VGA2PCIe in org.opencastproject.capture.impl.ConfigurationManager.properties looks like: capture.device.VGA.type=VGA2PCI capture.device.VGA.customProducer=v4l2src device=/dev/video0 ! queue capture.device.VGA.outputfile=screen.mpg capture.device.VGA.flavor=presentation/source capture.device.VGA.codec=ffenc_mpeg2video capture.device.VGA.buffer.bytes=536870912 capture.device.VGA.buffer.time=120000000000 Full *.properties file attached. Unfortunately it still fails. opencast.log (full log also attached) shows: 2011-08-02 15:06:17 INFO (GStreamerPipeline:435) - Successfully initialised 1 devices. That could be the audio device though....!?
2011-08-02 15:06:18 INFO (GStreamerPipeline:104) - Initializing devices for capture. 2011-08-02 15:06:18 INFO (GStreamerPipeline:124) - pipeline0 started. Then throws a bunch of WARNs and INFOs and the following ERROR: 2011-08-02 15:07:00 ERROR (IngestJob:146) - Ingestion failed with a value of -4 To me it looks like we have a another problem in addition to the VGA2PCIe recording not working as well... Help appreciated!

Now the Gstreamer pipeline is working properly and I assume matterhorn will also work, will try that next. And I agree it would be great to add that to the FAQ!

We got 1, we want at least 2 Sebastian, This is due to a misconfigured driver option. You need to supply v4l_num_buffers=2 while installing the kernel module. If you use Epiphan's make file, you should edit the insmod line to have that kernel option. I have attached a modified make file for your convenience. example: insmod vga2pci.ko v4l_num_buffers=2 Micah
