Hi there.
I posted to this mailinglist last December:
http://opencast.3480289.n2.nabble.com/Matterhorn-users-epiphan-VGA2PCIe-instead-of-VGA2USB-td5819489.html
Now we got all the hardware together and recently started to install a
Matterhorn Capture Agent and used an Epiphan VGA2PCIe card.
Would you recommend to install trunk or wait for 1.1 or use 1.0 and
the patch Micah Sutton recommended (unfortunately all efforts to get
the patch from him or contact him have failed so far)?
Go for 1.1! Its nearly finished and a huge improvement. The RC1 is
currently in QA and I guess the RC2 will be cut in a few days, because
of the minor problems that we found. Use the code from the SVN branch
here http://opencast.jira.com/svn/MH/branches/1.1.x/. I don't think that
there will be many changes comming up and the APIs and database is
stable so that you just will need to do a few svn updates to have a
stable 1.1 version.
In general the card is working. We used mplayer with the epiphan
recommended parameters and can view the VGA input live image.
These don't work for me too. There is a minor error in the docs. Try
this (assuming that /dev/video1 is your epiphan device):
mplayer -tv noaudio:driver=v4l:outfmt=bgr24:device=/dev/video1:fps=15 tv://
We also successfully installed Matterhorn trunk with MOCK inputs, so
far everything seems to be working well.
But now we don't know what the next steps are: What we need to do to
make the card work with matterhorn.
I you used the installer for the capture agent
(http://opencast.jira.com/svn/MH/branches/1.1.x/docs/scripts/ubuntu_capture_agent/install.sh)
and the recommended hardware everything should be configured already and
you simply will need to schedule a recording on your core system.
If you did not use the installer or you use different hardware have a
look at this page on how to configure the capture agent:
http://opencast.jira.com/wiki/display/MH/Capture+Agent+Configuration+%28Trunk%29
Do we just need to get the VGA2PCIe card working with Gstreamer and
use a customProducer in Mattergorn config?
For the epiphan you would need to add the following at the end of
$FELIX_HOME/conf/services/org.orpencastproject.capture.ConfigurationManager.properties
capture.device.SCREEN.src=/dev/video1
capture.device.SCREEN.outputfile=screen.mpg
capture.device.SCREEN.flavor=presentation/source
capture.device.SCREEN.codec=ffenc_mpeg2video
capture.device.SCREEN.codec.bitrate=2048
capture.device.SCREEN.codec.container=mpegtsmux
capture.device.SCREEN.framerate=5
And don't forget to add SCREEN to the capture.device.names-property in
the same file.
I hope I could help you with this information.
Good luck
Rüdiger
