Note: The getUserMedia calls with ?? new MediaStream() fallback (lines 2502, 2529)
ensure we don't get undefined when calling .getVideoTracks()[0] in non-secure contexts
where mediaDevices?.getUserMedia?.() returns undefined due to optional chaining.

instead of falling back to new MediaStream() we could simply check for publishOptions.useRealTracks && window.navigator.mediaDevices?.getUserMedia above
