Specify which audio track or PID is used for transcription in a service using the Audio Selection feature.
NOTE: This feature is available for SRT and RTMP inputs only at this time.
Default - Uses the first track of audio from your stream.
Track - Allows you to specify an audio track for transcription. Add the track number and hit 'save' to apply. Only a single track can be specified. Audio tracks in a stream are counted sequentially starting from 1. For example, if your SRT stream has four audio tracks and clean commentary is isolated on track 3, specify 'Track' '3' as your selection.
PID - Allows you to specify the PID (instead of sequential track order) in your stream as the audio to use for transcription. Only a single PID can be specified. For example, if your stream includes audio in multiple languages, with French dialogue on PID 1003, specify 'PID' '1003' as your selection.
