The Live-Recorder Task saves the live stream in chunks, therefore this task periodically:

  • generates a chunk
  • creates a Workflow to ingest the chunk into the MMS (it will be a new Media Item)
  • an 'onSuccess' event is generated for each ingested chunk

When the Live-Recorder task finishes, the output of this task is all the generated chunks. Since the onSuccess event is used to process each generated segment, the output of this task (all the chunks) can be retrieved connecting a Group-Of-Tasks to it.

Live Recorder example

The Workflow ingested by the MMS Task Manager to add the generated chunks will have the following variables:

  • currentUtcChunkStartTime, integer, UTC Start Time of the current chunk
  • currentUtcChunkStartTime_HHMISS, string, Local Time having the HH:MI:SS format
  • previousUtcChunkStartTime, integer, UTC Start Time of the previous chunk
  • recordingCode, integer, delivery code of the Live Recorder
  • ingestionJobLabel, string, ingestion job label of the Live Recorder

The JSON format specifies the metadata associated to each Media Item (chunk), however, the following metadata are added and filled by the MMS Task Manager:

  • title, a custom Title containing the stream name (configuration label), the start and end time

  • utcStartTimeInMilliSecs, this is a field added into the userData json and represents the Start UTC time of the Media Item

  • utcEndTimeInMilliSecs, this is a field added into the userData json and represents the End UTC time of the Media Item

  • Here follows some examples (body of the POST)
