thanks. however if I try to use camtasia,how to i configure matterhorn to use it. Thanks,
Hello, It's good to note that recording the CA's own screen is a highly experimental feature, I agree with that, but I wouldn't say that one needs to purchase third party software to do that. Gstreamer certainly can, and that means that our capture agent is likely to do it, too. Consider this pipeline: ximagesrc ! ffmpegcolorspace ! queue ! mpeg2enc ! mpegpsmux ! filesrc location=output.mpg . Running this with gst-launch succesfully records the screen, so I guess that you could use this profile in your capture agent (adding some sugar): capture.device.ScreenCapture.type=CUSTOM_VIDEO_SRC capture.device.ScreenCapture.customProducer= ximagesrc ! queue ! ffmpegcolorspace ! videorate ! videoscale add-borders=true ! video/x-raw-yuv,width=1920,height=1080,rate=25/1 ! queue capture.device.ScreenCapture.flavor=presentation/source capture.device.ScreenCapture.outputfile=screen.mpg capture.device.ScreenCapture.src=/dev/screen Note that ideally you need to adapt the values of width and height to match your actual screen size. Otherwise you may lose quality due to rescaling. Also, make sure that you add the name ScreenCapture to the property capture.device.names, so that it appears in the Schedule UI. *Bear in mind that this is an advanced configuration of the capture agent*, and that *this may not work at all*. I don't have a capture agent myself to test if it works, but *it should work with minimal changes to the suggested customProducer parameter.* However this has its limitations: you are forced to capture the whole screen, not a specific window (although ximagesrc does allow that possibility). In any case, *make a backup copy* of your config file, so that you can revert these changes easily and go back to a working capture agent in no time. Of course, you will probably capture in a simpler way and with better quality using 3rd party software, like Camtasia, which is a great product with many satisfied costumers. However, as a member of the Opencast community, I personally prefer to inform you about the purely-Matterhorn alternatives (emphasizing again the fact that what you intend to do is * experimental*) and encourage you to give them a try.

I cant find any folder or file with the name encoding and workflows in $FELIX_HOME/etc. what i can just see are two files named gosh_profile and motd. Thanks, Yemi Place the file containing the encoding profiles in the encoding directory (for trunk this would be $FELIX_HOME/etc/encoding) and the workflow definition in the workflows directory (for trunk this would be $FELIX_HOME/etc/workflows). You may have to restart Matterhorn. Once the definition has been loaded you should be able to scheduling captures with that workflow using the dropdown box at the bottom of the scheduling UI. ________________________________ From: adeseye a.
