Android: Media device stream not released

Trying to dispose of the local media stream doesn’t seem to work correctly. I am calling:

localStream.getTracks().forEach(t => t.stop());
localStream.release();

But signs are pointing to it still being used.

• I can see camera related logging (org.webrtc.Logging: CameraStatistics: Camera fps: 30) continuing on my main device (Nexus 5X, Android 7.1.1) and similar behaviour on another device (Samsung Tablet, Android 5.1.1).
• Device continues to feel hot.
• Battery stats show the usage for the app continues to use the camera.

I think https://github.com/oney/react-native-webrtc/issues/101 might be related to this.

@maximovicd I have managed to reproduce your solution.

stopCapture only exists on VideoCapturerAndroid so the VideoCapturer instance needs to be cast back.

@zxcpoiu This is the VideoCapturer reference that needs to be kept and have stopCapture called on. https://github.com/oney/react-native-webrtc/blob/master/android/src/main/java/com/oney/WebRTCModule/WebRTCModule.java#L323

It also seems to fix https://github.com/oney/react-native-webrtc/issues/101 for me.

I will try and find the time to get a PR together. I need to get a better understanding of WebRTCModule.java and when stopCapture should be called first.

I’ll have the time to look into this issue next week.
