Multi-audio support
The Dolby OptiView platform supports multi-audio ingest and delivery with our HESP solution. This functionality is perfect for use cases such as live events where multiple languages or commentary may be required.
caution
This functionality is only supported through the SRT Pull ingest method. Playback is only supported on web.
Configuring multi-audio ingest and playback
To deliver multi audio SRT the following steps must be taken:
- Within your dashboard configure your SRT listener endpoint.
- Configure your expected incoming "Audio tracks" by specifying a language, label, and the expected PID.
- Start the Channel and begin ingesting video and audio into the engine.
- Your output will be available for playback on web only via the channel alias.
- You can validate the audio tracks are being delivered via the demo player :
https://demo.theo.live/?channel=YOUR_CHANNEL_ID
