Feature

Current Behavior

No TSR actions to start/stop External output in vMix

New Behavior

TSR actions to start/stop External output in vMix are added.
Note: Those actions are not taking the External mapping and timeline objects into consideration. To avoid undefined behavior, either use the timeline or the actions to control the External output, not both.

Testing Instructions

When used with Sofie, it can be tested using the autogenerated buttons in the Playout Gateway section of Sofie settings.
Press Start External and verify if the External indicator lit up red in vMix.
Press Stop External and verify if the External indicator went back to grey in vMix.

Other Information
