As reported by Alexander Bias:
In etc/services/org.opencastproject.workflow.handler.textanalyzer.TextAnalysisWorkflowOperationHandler.properties I was surprised to see this content:
> # Configuration for the video segmentation properties
> # Number of consecutive identical frames in a 1 frame-per-second movie that it
> # takes in order to assume a new scene (defaults to 5).
> #stabilitythreshold = 5
The content is quite similar to etc/services/org.opencastproject.videosegmenter.ffmpeg.VideoSegmenterServiceImpl.properties and has nothing to do with TextAnalysis at first glance.
