[Freeswitch-users] Conference audio issues when Verto user sends video to audio-only conference

[Chad Phillips]

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use outdated WebRTC APIs, and I doubt iOS supports them in their brand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.
