I not sure what you mean by a vision mixer, But are you referring to adding the captions as part of the video feed to the live stream? in a PIP somewhere on screen?That would be an “overlay” style of CC. it cant be turned off/on if viewers don’t want the captions. We are looking for the “embedded ” style that is inserted on a line of the player’s code, I’m not sure if thats’ the correct term. looking the Wowza site is see reference to: In-stream (embedded) CEA-608 captions (Line 21 captioning)
