Hello Adam,
Sandeep is working with me at Texas A&M University-Commerce. Going off the documentation in the wiki for the trunk capture agent there doesn't seem to be enough information to get a webcam working. Ideally the goal is to use the Logitech C910 with a MPJEG stream which the camera can provide natively at full resolution (1080P) at 30 FPS. http://opencast.jira.com/wiki/display/MH/Install+Matterhorn+Capture+Agen t+(Trunk) The example given for a webcam doesn't work since the source is a filesrc through a CUSTOM_VIDEO_SOURCE type property, and we're not sure the requirements of a pipeline for Matterhorn (is it supposed to end with a queue, xvimagesink, filesink, something else?). We've tried plugging in something that works in the command line but it doesn't seem to be working in Matterhorn. There's also a V4L2SRC type property that says it can be used for webcams like the C910, but how is the resolution and format (raw, mjpeg, etc.) specified? We are running some more tests and will post some log files soon. Even without the log files though, there isn't a clear example of how to use a webcam or full documentation for a V4L2SRC type property. I realize we're using the trunk and things are a working in progress. Should we hold off on trying this until the documentation is further, or is there more documentation somewhere else we're missing?

We used this code to test the webcam. $ sudo gst-launch v4l2src device=/dev/video0 ! 'video/x-raw-yuv,width=640,height=480,framerate=30/1' ! xvimagesink And it works successfully. The example configuration in the wiki for the trunk version does not work with the webcams. Does anyone have working example of the configuration file for a camera like logitech c910?
