I’m not negotiating video (useVideo: false, useCamera: “none”).

But because of this iOS-only bug: https://bugs.webkit.org/show_bug.cgi?id=179363

I’ve been passing an existing MediaStream to the Verto library that has both audio and video tracks.

I’m pretty sure the reason video still gets sent is because our Verto libs use outdated WebRTC APIs, and I doubt iOS supports them in their brand spanking new implementation.

Of course adapter.js is supposed to fix all this, but it’s not perfect.

I did eventually figure out that I could clone the original existing MediaStream and remove the video track from the clone, which solved this particular issue.
