-----------------------------------
I verified last night with 8 recordings 1 minute apart with a duration of 1.5
hours that it was the drop frames that was causing the issue. If you want to
patch the problem it is:

> Key: MH-8851
> URL: http://opencast.jira.com/browse/MH-8851
> Project: Matterhorn Project
> Issue Type: Sub-Task
> Components: Capture (Devices and Software)
> Affects Versions: 1.4, 1.3
> Reporter: Adam McKenzie
> Assignee: Adam McKenzie
> Priority: Release Blocker
> Fix For: 1.4, 1.3
>
> Attachments: removeDebugToDotAndAsyncMaxBuffers.patch,
> revision-11044.diff, svn.log, trunk.diff
>
>
> I cannot reproduce the issue on 1.2 in conditions that it reliably happens in
> 1.3. Therefore, I am going to go through all of the commits after the svn log
> says the 1.2 branch happened for the capture agent bundle
> (modules/matterhorn-capture-agent-impl) to determine possible candidates that
> are issues. Then I will create tasks to revert the code and test it on
> capture agents to isolate what might be causing the issue.
