How do I test and influence my video transmission?
Upon entering a session and activating your video, a small window will open up. Here you can check your video feed and decide which quality it should have. The higher the quality, the more bandwidth is being used. Try lowering the quality if you have performance issues.
You can repeat this process by deactivating and reactivating the camera inside the BBB session, or by using the small arrow symbol on the option itself.
