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 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
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:

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

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
