3 years ago Hi,
Looks like cordova-plugin-iosrtc gives remote MediaStream with no video stream in some cases.
The issue is how incoming WebRTC events (RTCPeerConnection.onaddstream, RTCPeerConnection.ontrack) are handled by Swift function: Xcode->Plugins->PluginRTCPeerConnection:getPluginMediaStream
For instance, if we get first the audio track then getPluginMediaStream creates MediaStream with only audio stream and won't update it with more recent tracks (eg video) further, so we have black screen.
As we handle both .onaddstream and .ontrack events on ApiRTC level, track handling may be commented on plugin level
as a temporary workaround (need to investigate it deeper):
PluginRTCPeerConnection:peerConnection(_ peerConnection: RTCPeerConnection, didAdd rtpReceiver: RTCRtpReceiver, streams:[RTCMediaStream]) {
// comment internal content
}It should fix the issue

Hi, my team currently developing ionic cordova application where user can video chat with each other. We are using apiRTC to make it happen (actually credit are added to the dashboard). When we build app for iOS and install it on our devices everything works correctly until one of those devices (iphone xr ios 14.3) call to another one. When we do that we are getting black screen where remote-media should be and audio is not working anymore, after few seconds connection with devices disconnects automatically. This issue exist only on iOS and not on android.
We testing the next Uses Cases:
Android - Android ( SO versions 8 - 9 - 10) => WORK OK Android - iOS (ios 14.3) => failing with ICE_STATE_FAILED (android and ios device testing on same network and diferent network) iOS - iOS (same OS 14.3) => failing with Black Screen Only Remote, local stream show iOS- iOS (one with OS 14.3 and other with OS 13.7) => Failing Black Screen Remote on 14.3 ios, but on 13.7 (iphone s6) Remote and local show and all good.
and actually when we tried to use:
userAgent.getUserMediaDevices()only gets internal mic and only see one camera.We check and same behaviour occurs on the example apps mabe by apiRTC team.
To reproduce this issue you can use both example applications made by apiRTC team where the same issue exists:
