WebRTC error: getUserMedia not available

This looks like it is an issue with WebRTC, as it says that the module/command getUserMedia is not available. I did a bit of research on this, and it appears that this is not a Mattermost issue, but a WebRTC issue, that is a result of some of their upgrades. Please see the corresponding GitHub issue here, and the documentation on StackOverflow here that explains how you can fix this issue.

Does this help?
