Hi All,

I am finding that when we record from our Extrons, we're getting back only 1 media stream, it's causing all kinds of issues.  For example, cutting fails, because there is only one media stream anfd it's looking for */work.   The issue is that the faculty will definitely want to be able to cut and republish their media

So I'm trying to work out where exactly to put a clone directive as below

<!-- Clone directive to create work flavor -->
   <operation
     id="clone"
     exception-handler-workflow="partial-error">
      <configurations>
      <configuration key="source-flavor">*/source</configuration>
      <configuration key="source-tags">archive</configuration>
      <configuration key="target-flavor">*/work</configuration>
      </configurations>
   </operation>
<!--Clone directive to create work flavor --> 

At the moment I have it in Partial-publish.xml

which works but then creates additional */branded and */themed archives.

Plus whenever the faculty edit the media and republish, the clone configuration is rerun which creates another */work archive

Anyone able to advise, this obviously isn't the best place to put this, in the meantime I'll keep looking

Thanks in advance 

Regards

Hi All, 

So, I removed the clone operation as by then end of the test I had 8 */work archives, I rolled back to the standard unaltered workflows, I'm getting intermittent issues where the media details show an unknown file type

The workflow error details show


Workflow Operations show that the failure was at the inspection stage

The error in Error Details is 

job-operation
START_OPERATION
job-type
org.opencastproject.workflow
stack-trace
org.opencastproject.workflow.api.WorkflowOperationException: Unable to open catalog https://sgcapadmin.opencast.utoronto.ca/files/mediapackage/70f4d173-b052-42b0-a551-b00b10451c7f/7fa6228f-120f-4aec-b53f-4bf40a90f98e/dublincore.xml

If I search for that media on the share it doesn't exist 

Looking in the Opencast.log

I've attached the log for this time period, if someone would be willing to take a look that'd be great

However, if I re-import the event from the Extron, the media is imported and the workflows continues on to a successful conclusion

I'm testing on other network segments with other Extrons so far they've been OK, so it's potentially a dodgy device or something network related

I've tried this on several Extrons now, many end in a failure, all giving the same errors


Checking the path /srv/opencast/files/mediapackage/45ed2bc5-c015-43bf-a639-2cc15e99add6/876e40d7-3be1-40a7-9c18-0710087e2a5f/dublincore.xml failed  - doesn't exist however /srv/opencast/files/mediapackage/45ed2bc5-c015-43bf-a639-2cc15e99add6/ does

Really hoping that someone can shed some light on this, as we've already had a great deal of interest given the pandemic and I'd rather not say that we can not provide the service, I have a work around which involves re ingesting the media from the Extron which works but as you can appreciate that could potentially be a great deal of extra work

Hello,

We have the same problem on a random basis, have you come up with a more specific solution or idea where the problem might be coming from ?

Best regards
