You can use the custom producer if you wish you make a special pipeline. However, by default it will use the existing VGA2USB pipeline. For example, our configuration for the VGA2PCIe device looks like: capture.device.Screen.src=/dev/video0 capture.device.Screen.outputfile=Screen.mpg capture.device.Screen.flavor=presentation/source capture.device.Screen.buffer.bytes=536870912 > For the epiphan you would need to add the following at the end of > $FELIX_HOME/conf/services/org.orpencastproject.capture.ConfigurationManager.properties > capture.device.SCREEN.src=/dev/video1 > capture.device.SCREEN.outputfile=screen.mpg > capture.device.SCREEN.flavor=presentation/source > capture.device.SCREEN.codec=ffenc_mpeg2video > capture.device.SCREEN.codec.bitrate=2048 > capture.device.SCREEN.codec.container=mpegtsmux > capture.device.SCREEN.framerate=5 > And don't forget to add SCREEN to the capture.device.names-property in the > same file. > > I hope I could help you with this information. > > Good luck > Rüdiger > -- > > ________________________________________________ > Rüdiger Rolf, M.A. > Universität Osnabrück - Zentrum virtUOS > Heger-Tor-Wall 12, 49069 Osnabrück > Telefon: (0541) 969-6511 - Fax: (0541) 969-16511 > E-Mail: [email protected] > Internet: www.virtuos.uni-osnabrueck.de > _______________________________________________ > Matterhorn-users mailing list > [email protected] > http://lists.opencastproject.org/mailman/listinfo/matterhorn-users
