From what we know in Osnabrück it can not work. But maybe Ruben was
much mor successful than we were.

Then I must have misunderstood Ruben's mail.
To me it said that there was a one-line patch:

I was assigned the ticket to fix the problems with the resolution

but it turns out that the code was already in place (I think it is
Waldemar's work). There was a bug (a one-liner) that I think was causing
the problems. However I couldn't test it myself since we have no
official
capture agents in Vigo anymore, so Adam Mckenzie kindly tested the patch
in their agents. In his experience, it seems that the agent deals
well resolution changes, and the resulting media is OK.

Andreas,
As I pointed out several times already: there is no fix to this
problem. And if you want to get this fixed you have to turn to
epiphan or gstreamer, as this is not a Matterhorn related problem. It
is somewhere within the epiphan driver or gstreamer modules that the
signal about a resolution change gets lost.

Hi,
http://opencast.jira.com/browse/MH-8655
This fix did'nt make it into 1.3.1 it seems :)
What can I do to implement the fix locally?
Regards, Andreas

Subject: [Opencast Matterhorn] Patch to support resolution changes
not in
1.3.1?
Hi all,
This comes from this message:
http://opencast.3480289.n2.nabble.com/Matterhorn-users-Release-1-3-1-when-to-come-tp7580482p7580503.html
*Rüdiger said:*
There will be no fixes for the epiphan device regarding resolution
changes
in 1.3.1 that are not in 1.3.0 already. And the API for the
epiphan devices
has some bugs that we can not catch every resolution change. So
you will
need the scaler.
I was assigned the ticket to fix the problems with the resolution
changes,
but it turns out that the code was already in place (I think it is
Waldemar's work). There was a bug (a one-liner) that I think was
causing
the problems. However I couldn't test it myself since we have no
official

their agents. In his experience, it seems that the agent deals well
resolution changes, and the resulting media is OK.
I'm not aware of any other bugs in the API for the Epiphan devices.
You
mean the v4l, low-level API, or you mean the Matterhorn part? If the
problem is in the drivers, then I agree with Rüdiger since the
problem is
outside our control and we cannot fix it. But if it's about the
Matterhorn
part, I don't think there's anything else to add. Waldemar (or
whoever did
this) did a good work and the pipeline dynamically adapts to
changes in the
video size using the 'videoscaler' element, which does not need
external
signals to detect resolution changes.
I'd say this was a bug fixing rather than a new feature, since no
new code
has been added. I'd very much like this to be included in the
release, so
that we can save the new adopters some money.There are still two
months
until the winter semester, so if the agent does still have problems
with
resolution changes (which, as I said, shouldn't happen anymore),
they will
not go undetected and people will still have time to buy scalers if
they
really need to.
Best regards
Rubén
