track mute/unmute events

[bkervaski]

Hi All!

Looking for guidance .. since there is currently no support for track mute and unmute events, how are you determining whether or not the track is muted? Or, more specifically, in the case of video, whether or not the video track contains video?

Thanks for any advice :)

We do support enabled see implementation for setter/getter here:

• https://github.com/cordova-rtc/cordova-plugin-iosrtc/blob/master/js/MediaStreamTrack.js#L68

It will disable/enable track on WebRTC level:

• https://github.com/cordova-rtc/cordova-plugin-iosrtc/blob/master/src/iosrtcPlugin.swift#L1021

• Audio muted if video is muted before starting the connection. #652

Thanks again for the help.

My problem really is remote video, if it comes in muted, I have no way to know. Results in a black uiview with no indication if there is video streaming or not (so I can't reconfigure my app's UI accordingly, etc).

I've tried everything I can think of aside from hacking on the uiview and cordova, for example, just looking for absence of pixels other than black, etc. I might head there next, not sure if I'll get very far.

Big thanks :) :) :)

You should be able to listen to MediaElement events onload/onpaused/oncanplay/onca playthrough to build a loader.

You can also iterates over MediaStream tracks to see if it's enabled and or audio only tracks. Your signaling may also he'll you with that.
