Hi,

You can override the default videoConversion queue to increase the max number of threads that the queue can use. By default it's set to 1.

Here is a contribution to set it to5:

<require>org.nuxeo.ecm.platform.video.workmanager</require>
<extension target="org.nuxeo.ecm.core.work.service" point="queues">
  <queue id="videoConversion">
    <maxThreads>5</maxThreads>
    <category>videoConversion</category>
  </queue>
</extension>
