Which did you choose? I chose 5=PAL and 1=Composite0, and the file /opt/matterhorn/capture-agent/device_config.sh shows this, which I understand to be correct: #! /bin/bash v4l2-ctl -s 4 -d /dev/camera v4l2-ctl -d /dev/camera -i 0 >> To me it seems, that the capture client somehow modifies the v4l2 >> settings, >> since VLC shows OK before the capture, but bad after the capture.

The card works correctly directly after bootup, and even with matterhorn started (which happens on bootup): I can see video on VLC (v4l2://). But with starting a capture 2 things happen: 1. The capture is green (except for a thin line at the right upper corner showing moving content) 2. A subsequent call to VLC (v4l2://) also gives me a green picture. Only remedy atm is to switch over to NTSC (before capture) and then back to PAL (during capture) as mentioned in my previous post; then the capture will be all right (lest the few seconds in the beginngin NTSC was set) As posted in my answer to Ruben I confirm this to be Adam Mckenzie's issue https://opencast.jira.com/browse/MH-5404, and hope for some soon fix/workaround. ATM I'm checking the matterhorn Trunk version, whether it does any better, and will report on any success/failure. Greetings and lots of thanks for the detailed support and ideas, Andreas -- View this message in context: http://opencast.3480289.n2.nabble.com/Matterhorn-users-Problem-with-customProducer-in-capture-impl-configurationmanager-properties-tp5970958p6004087.html Sent from the Matterhorn Users mailing list archive at Nabble.com. _______________________________________________ Matterhorn-users mailing list [email protected] http://lists.opencastproject.org/mailman/listinfo/matterhorn-users
