Greg,
Did you find a work around for that OpenJDK6 issue on 10.04, or are you
using Sun Java 6?

Dear Rudiger and list
Hi Rudiger I am very glad for your very positive experience from Matterhorn
1.3 but unfortunately this is not the case here in Tel Aviv, at least not
regarding our efforts to switch from 1.2 to 1.3.
We are trying for some time to install 1.3 on Ubuntu 10.04 with no success, I
wrote to the list about the problem but there was no respond from the
community. We also try to make the installation on Red Hat Linux following
precisely the instructions on the website but again with no success.
Is that the mail that I just replied to? I know that 1.3 works on 10.04
since that's what all of my testing VMs are running, so chances are it's
a local config issue.

The product installation documentation looks clear enough but then again we
are failing we the installation time after time.
I wonder if there are more people having problems trying to install 1.3 or is
it that we have some unique problem in TAU.
Best
Jack

Subject: [Opencast Matterhorn] 3 weeks with Matterhorn 1.3 in Osnabrück
Hi list,
I guess after 3 weeks with Matterhorn 1.3 in production here in Osnabrück it is
time to give a short feedback about our experiences.
And I must say my feedback is extreme positive. We record 19 lectures a week 90
minutes each with 7 CAs. We have recorded a few less than 60 lectures yet and
not lost any recording yet and the problems that we encountered are from my
point of view minor and in many cases not really matterhorn related. The
confidence monitoring in the CA is currently very helpful to really make sure
that everything works as expected during the recording. We had no reason to
restart the Matterhorn servers or a capture agent yet (with one exception, see
problem 2.)
The problems we encountered:
1. VGA is scrumbled: This is a well know issue when the resolution of the VGA
is changed while the PC is already connected to a recording VGA2USB device. One
solution is to reconnect the VGA then. But we started to include the StarTech
VGA-scalers that are recommended for the Capture Agents anyway.
2. VGA video gets stuck for a few seconds/minutes but it recovers after a
while. I created a ticket for this http://opencast.jira.com/browse/MH-8799. But
in general I suppose that I simply need a faster CPU. But to make sure it is
not based on some artifacts I restarted the PC.
3. Audio not loud enough. After a hardware problem (damaged power
supply) the volume on the amplifiers in the room was set too low. This was not
in any way Matterhorn related.
4. On one CA the lecturer video was b/w. This was caused by a broken
s-video-cable.
5. In one of over 60 recordings we needed to start the recording manually, for
an unknown reason. The scheduled recording aborted after a few seconds. We
noticed this with the CM and started the recording manually.
6. If we edit the metadata in the trim hold state, the date gets lost.
This is a known issue too.
I wanted to use MP4/H.264 for the streaming only, as you might have seen in my
other mail some weeks ago. In the meantime we decided to use h.264 only for the
higher qualities. For low and medium quality we switched back to FLV as this
works much better for us and is better supported by the Matterhorn 2go app.
This is by far the best semester start that we ever had. I hope that others
have made similar good experience.
Rüdiger
