Watcher produces black screen indefinitely

[andrew103]

When running the code, viewer pages are completely black and don't seem to update with video feed. The broadcaster sees that a viewer is joining and they seem to exchange offer/answer successfully.

Steps to reproduce
Run the code as usual with node.

Expected behavior
Live video feed to display in the watcher's browser.

Desktop (please complete the following information):

Server/Broadcaster:

• NVidia Jetpack 4.3 (based on ubuntu 18.04)
• Chromium
• 80.0.3987.87

Viewer (1): Same as Broadcaster

Viewer (2):

• Ubuntu 18.04
• Chrome
• 81.0.4044.138

Viewer (3):

• Android 10
• Chrome
• 81.0.4044.138

Adding controls and pressing play begins the video feed, but autoplay doesn't seem to work for some reason.

Found the solution. Apparently most browsers won't autoplay unless provided with the "muted" option in the video tag. Adding this option fixed the problem immediately.
