Hi Sebastian, I think I have figured out the bug in the code that is causing you problems. We actually only look for "Epiphan VGA2USB" and "Epiphan VGA2PCI" devices but not PCI-e Epiphan products. I've created the issue at:
https://opencast.jira.com/browse/MH-7191 In the mean time as a work around could you add capture.device.SCREEN.type=EPIPHAN_VGA2USB To your ConfigurationManager.properties file, this will skip the code trying to detect the device because you have specified it. Also could you do me a huge favor and run: v4l-info /dev/video0 and email me the output so that I can fix this in our codebase?
