When in a video session, I can hear the subscriber but I can't see them. I see only a black screen.
- Video API
- Video Quality
- Make sure that the subscriber.subscribeToVideo() is set to true.
- Make sure that the Publisher on the other side has publishVideo() set to true.
If you are using a Routed Session, it is possible that due to bandwidth limitation, the Media Server has triggered Audio-Only Fallback.
For more information, see How do I know if I have gone into Audio Only Fallback mode?
