Hi Jonathan, I am guessing that v4l-info or jv4l-info doesn't work as it should on Centos luckily there is a workaround for it not working. In the
/opt/matterhorn/felix/conf/services/org.opencastproject.capture.impl.ConfigurationManager.properties File at the bottom where you have the devices defined such as capture.device.camera.src=/dev/camera capture.device.camera.outputfile=camera.mpg capture.device.camera.flavor=presenter/source capture.device.camera.buffer.bytes=536870912 capture.device.camera.framerate=30 You will need to add the line: capture.device.camera.type=V4L2SRC Which will tell matterhorn that this is a v4l2 device without using v4l-info or jv4linfo.

To double check the permissions issue I also tried it as root. I realize the install script is for ubuntu. Basically what the install script does is setup some globals and then pulls down individual scripts that are used for each stage of the process. There are scripts for creating the user, installing the dependencies, compiling matterhorn, etc. The install script is also setup to look for these scripts first before attempting to pull them down. That means one can easily grab the separate scripts, modify them to work for centos, and have the installer use them. Here is a list of those scripts: SETUP_USER=./setup_user.sh INSTALL_VGA2USB=./install_vga2usb_drivers.sh SETUP_DEVICES=./setup_devices.sh SETUP_DEPENDENCIES=./setup_dependencies.sh INSTALL_DEPENDENCIES=./install_dependencies.sh SETUP_SOURCE=./setup_source.sh SETUP_ENVIRONMENT=./setup_environment.sh SETUP_BOOT=./setup_boot.sh Near the bottom of the script each one of these is called in turn. I commented out the calls for SETUP_DEPENDENCIES, and SETUP_BOOT. I then copied setup_user, and install_dependencies. I modified setup_user to remove ubuntu specific things, and I modified INSTALL_DEPENDENCIES by removing all of the ubuntu package installation stuff leaving felix and jv4linfo. INSTALL_VGA2USB, SETUP_DEVICES, SETUP_SOURCE, and SETUP_ENVIRONMENT I left as is. I then installed the centos equivalents for the dependencies listed in setup_dependencies. There were: gcc, glib2-devel, subversion, xawtv, gstreamer, gstreamer-plugins*, gstreamer-devel, v4l-utils, kernel-devel, ant, ant-* acpid, alsa-utils, curl, ntp, wget, openjdk, and openssh are installed by default. I manually installed maven and ivtv-utils Finally I had to add the centos location for java to the list of java patterns which the install script looks at to find java. After all this, the hardware was detected and the epiphan driver (vga2usb-3.27.0.4-SCL-2.6.32-131.6.1.el6.x86_64.tbz) was installed and loaded successfully. Matterhorn built successfully and passed all the tests. Matterhorn also starts up and communicates with the server. The error below is a result of scheduling a recording through the admin server. I have attached the modified install scripts for those who might be interested.
