Composite recording

The On-Premise Recording SDK supports two recording modes:

• Individual recording mode: This is the default recording mode. The SDK generates one audio and/or video file for each UID.
• Composite recording mode: Generates a single mixed audio and video file for all UIDs in a channel, or mixes the audio of all UIDs in the channel into an audio file and the video of all UIDs into a video file.

See Differences between individual recording mode and composite recording mode to decide which mode you should use.

Before continuing, follow the Quickstart guide to integrate the Recording SDK and implement the basic recording functionality.

The implementation of composite recording is largely similar to the steps in the Quickstart guide. The main differences are in the configuration parameters and the APIs used.

Refer to the following call sequence diagram to understand the recording workflow.

The composite recording mode supports a specific set of APIs. Calling unsupported methods in the wrong mode has no effect. When using the composite recording mode, the following methods do not work:

• setRecorderConfigByUid
• enableAndUpdateVideoWatermarksByUid
• startSingleRecordingByUid
• stopSingleRecordingByUid
