Configure input stream selection

Input stream selection allows to define rules to select input streams from input file. Input streams include video, audio, subtitles and metadata inputs.

Edit input stream selection parameters

1. Click to edit configurations.

   • Video
   • Audio
   • Subtitle
   • Metadata

2. Configure parameters, then click Apply.

   Tip: Parameter descriptions:

   • Video
   • Audio
   • Subtitle
   • Metadata

3. You can tick the Mandatory checkbox for each audio, subtitles or metadata input stream.

   A new Service always has a non-removable and mandatory video input stream preconfigured.

   When an encoding job is started, if some of the input streams have the Mandatory option activated, the job will only be completed if the ingested asset contains streams corresponding to the selection criteria defined for each input stream.

   Examples:

   • Let's consider a service with only two input streams: the default video input and an audio input with no particular selection criteria (Codec: any, Languages: any, PID: any, etc.), where the audio input stream is declared as Mandatory: if an encoding job is launched for this service, it will fail if the ingested asset does contain at least one audio stream.
   • Let's consider another service where a Subtitle input stream with Arib B24 type is declared as Mandatory: the job will fail if the ingested asset does not contain at least one subtitle stream with Arib B24 type.
