Hi Ruben,
I'm a little confused. We all know that the update of the namespaces was
a notworthy change that had several implications. But nobody was against
the proposal for this update, as far as I remember.
This current issue seems to me that the Galicaster that is not
maintained by the Opencast community but Teltek and some other people
that are interested in it is not compatible with MH 1.4 anymore because
of the namespace changes. (again: correct me if I'm wrong, I did not
follow this issue to much). And now you and some other people try to
provide a backwards compatibility patch, to make a vendor CA compatible
to the upcomming release, which is probably a good idea.
But who other than you or somebody else assosciated Teltek should
provide this patch? You are not fixing a bug, you want to increase the
compatibility of your device. If you want to achive this you have to
spend as much time on this issue as it takes, you cannot expect that
somebody else is interested in fixing this problem. At least we in
Osnabrück do not care about this and Entwine probably not too.
Just my 2ct

I'm not willing to commit more fixes or dedicate more time to an issue

Hi James,
We had a similar problem when the NCast pr720 was not
sending the namespace and we put a temporary workaround in
place (Ncast has now fixed it). You are welcome to try it with
Galicaster, but I am not sure if it will work... It's in
IngestServiceImpl.java:
@@ -313,7 +325,17 @@
InputStream manifestStream = null;
try {
manifestStream = manifest.toURI().toURL().openStream();
- mp = builder.loadFromXml(manifestStream);
+ // Hack for ncast BEGIN
+ StringBuffer manifestXml = new StringBuffer(new
Scanner(manifestStream).useDelimiter("\\A").next());
+ if (manifestXml.indexOf("xmlns=") == -1) {
+ int pos = manifestXml.indexOf("<mediapackage");
+ if (pos > -1) {
+ manifestXml = manifestXml.insert(pos + 14,
"xmlns=\"http://mediapackage.opencastproject.org\"; ");
+ }
+ }
+ mp = builder.loadFromXml(manifestXml.toString());
+ // mp = builder.loadFromXml(manifestStream);
+ // Hack for ncast END
} finally {
IOUtils.closeQuietly(manifestStream);
}
Thanks,
Rute

Hi,
Does anyone have Galicaster (1.2.1) working
with MH1.4/Trunk? We are
able to schedule recordings and they are captured
on the CA (VGA test
with white noise) but when the (default) workflow
has finished there is
nothing to see or hear. The Operations show that
capture has has been
skipped, but ingest and rest of the operations all
succeeded - though
they report no tracks found in the log.
Same CA works with 1.3 so it could be our
inexperience setting up MH
that is the problem.
While I'm not familiar with the way Galicaster does
its ingest, we did
change the XML namespaces on the mediapackages in 1.4.
Your symptoms
exactly match what happens when an older mediapackage
is ingested into a
1.4 core, so I suspect that's what's going on. We've
discussed this a
couple of times in the dev meetings, but we haven't
come up with a
proposal to handle this case yet. It's simple to fix
(I do it with a
one line sed script in my study system), just a matter
of someone
writing up the namespace mangling that's needed!
It probably went over my head at the time, still so much
too learn. Gives us a starting point even of we just fudge
Galicaster for now. Is there an issue for this I can't
find one?
Thanks,
James
