Statistics Writer Workflow Operation

ID: statistics-writer

Description

The statistics writer operation can be used to publish statistics about a video to a statistics backend such as InfluxDB. Currently, it only writes the length of the video in seconds to the data base. It can be configured to write the negative length and can thus be used for retract workflows, too.
