Note You cannot disable channels after you enable them. If you set this parameter to 0, the production studio references video resources in a layout without using channels. If you enable channels for the first time, make sure that the production studio is in the idle state. After you enable channels, a new layout that references video resources by using channels is generated to replace the original one. Therefore, you must specify video resources for channels. You can use the channels to change the playback progress or status. If the video resource, preview, and program modules of the production studio use the same video source, the three modules display the same content.
1
SyncGroupsConfigstringNo

The multi-view synchronization configuration. You can specify this parameter to synchronize multiple video sources.

There are two modes of multi-view synchronization.

  • A value of 0 for the mode field specifies the streamer mode. In this mode, multiple video sources are synchronized based on the settings by the streamer.
  • A value of 1 for the mode field specifies the conference mode. In this mode, all video sources are synchronized.

In the streamer mode, the hostResourceId field specifies the video source on the streamer side.

In the conference mode, the hostResourceId field is not available. You need to provide only resource IDs that are required.
