Andreas,
Don't be sorry - you've got me on the right track after not a little
head scratching!
One last thing - do you deploy the workspace-stub or the full workspace
to your worker nodes?

Sorry David, I can't really tell a lot, I'm not so deep into all this
and rather the trial-and-error type ;)
The other thing our admin did was to upgrade Java from version 6U15 to
6U30. But that didn't really help here.
What helped was the indicated line in the config on the *worker* node.
Maybe just check if you get some log lines like
2012-02-02 14:31:37 INFO (WorkspaceImpl:245) - Downloading
http://server ....
on your worker node, just before your mentioned error message starts.
While it should not download the file (and hits the 2GB limit there)
but rather get it from the shared storage.

Hmm ok that didn't work :-( Might be that I didn't quite understand
what was needed. I now have:
# The path to the repository of files used during media processing.
org.opencastproject.file.repo.path=${org.opencastproject.storage.dir}/files
# The interval in milliseconds between two rounds of dispatching in
the service registry. The default value is 5s, and
# a mimimum value of 1s is enforced due to performance reasons. Set
to 0 to disable dispatching from this service
# registry.
#org.opencastproject.serviceregistry.dispatchinterval=5000
# The base URL of the file server. When using a shared filesystem
between servers, set all servers to use the same URL.
# If this is set to any value other than
${org.opencastproject.admin.ui.url}, the admin and file servers must
use a
# single sign on (SSO) solution such as CAS to avoid requiring users
to perform multiple logins.
org.opencastproject.file.repo.url=${org.opencastproject.admin.ui.url}
But it still fails :-( Did I get something wrong?

Thanks Andreas,
In my test one the encoded file was 2.1G so this could be the cause.
I've made the change in our dev environment and will report back
once the test has run.

Hi David,
we have been having the same issue for some videos. As you already
said, this occurs only with some files, and the reason we found
here for the failure is 2fold:
1st the configuration admin-worker: as you already said it only
happens there
2nd the limit of 2GB for Jetty downloads: for some reason the
worker *downloads* the prepared files, and if they are of a size >
2GB it will cut them at exactly 2GB wich causes the "moov atom not
found" error.
Our admin found this to fix the issue:
in
/opt/matterhorn/felix/conf/config.properties
set
org.opencastproject.file.repo.url=${org.opencastproject.admin.ui.url}
as suggested in http://opencast.jira.com/browse/MH-8032
Hope this helps you also, regards, Andreas

Hi All,
We're seeing failures on our production instance in encoding
certain files. The failure is consistent and always happens at the
encoding of the presentation for the hold state preview. The log
message looks as follows:

and null
The error seems to happen when some or all of the presentation is
the epiphan capture card (seen when no source was connected). I
can reliably reproduce this with certain recordings on both our
production and development environments (separate admin/worker)
but not my local build (all in one). This, with the error
"Operation not permitted" suggests some kind of workflow/file
repository error - the ffmpeg docs lean towards this being 1 of
the files doesn't exist. However this doesn't explain its
reproducibility with certain packages and not others.
So far I have verified:
1) The profile creates a valid working copy (i.e ffmpeg isn't
encoding to to 0b file)
2) the file doesn't exist at:
/data/matterhorn/workspace/mediapackage/eeaa4715-e6c5-444e-88eb-4c0835263a25/632f74bf-0dfe-4323-9a5a-ae6f44fbf619/Presentation.mp4
But I don't know if one expects it to be cleaned up after the
failure ...
Any help in solving this is apreciated
David
