Workflow Definition file

A workflow definition file is a YAML file describing the steps to perform when a file create event is received. This example defines that an ABR_TRANSCODE and TRANSCRIBE will be executed in parallell and as it has no dependencies they will be executed immediately. The step VOD_PACKAGE depends on that both ABR_TRANSCODE and TRANSCRIBE have completed. Last step is the CLEANUP step which depends on the VOD_PACKAGE to be completed.

steps:
  - type: ABR_TRANSCODE
    dependsOn: []
  - type: VOD_PACKAGE
    dependsOn:
      - ABR_TRANSCODE
      - TRANSCRIBE
  - type: TRANSCRIBE
    dependsOn: []
  - type: CLEANUP
    dependsOn:
      - VOD_PACKAGE

If you want to skip transcription you write the following:

steps:
  - type: ABR_TRANSCODE
    dependsOn: []
  - type: VOD_PACKAGE
    dependsOn:
      - ABR_TRANSCODE
  - type: CLEANUP
    dependsOn:
      - VOD_PACKAGE

Steps

Supported steps are shown in the table below.

Type Description
ABR_TRANSCODE Transcode source file to a set of variants with different bitrates and resolutions.
TRANSCRIBE From the source file transcribe and generates subtitles.
