The Preview & Program viewer allows users to view the following scenes of your Stream OBS:
Sync: this scene shows the current timestamp of the Stream OBS local machine and each active runner. This is used alongside the Runner Stream Source Panel to synchronize all streams before a run starts, and then monitor during the run in case adjustments are needed.
Preview: this is the current scene being previewed on OBS. The preview is automatically updated to Intermission whenever a run starts, and updates to the next run's layout when a run ends. This scene should be checked before switching to it in case any errors need fixing.
Program: this is the scene currently being streamed to Twitch.
Users won't be able to hear the stream through this panel - this has been tried in the past, but the sound quality is very poor. Therefore, in addition to this panel you should use a dedicated voice channel in your Discord server for tech to listen to the live audio (see Discord setup). There's little harm having the OBS Virtual Camera feed you'll be sending to NodeCG also being streamed to this Discord channel.
To set up this panel:
Start the Stream OBS and click "Start Virtual Camera". The virtual camera is set by default to broadcast the "NodeCG View" scene, which shows all three of the views above.
In NodeCG, navigate to the Settings workspace, and in the OBS Connection Panel click on "OBS Virtual Cam". This will open an instance of VDO.Ninja in a separate browser tab which will automatically grab your OBS Virtual Cam feed. You don't need to adjust anything on this page, just keep it open in your browser.
The Preview & Program viewers (on both the Main Workspace and OBS Workspace) will update their URLs to the VDO.Ninja scene created, and after a moment of loading, will show your OBS feed.
This should be a one time set-up panel, and should persist through NodeCG restarts, though if it doesn't load, repeating the above instructions will easily get it back. If a user refreshes their NodeCG page, they'll likely need to click a large PLAY button on the panel to resume viewing the feed.
