Webrtc 部分仅在 Release Build 上崩溃在 Debug 构建上工作正常

Question

[Solved] I am developing a Webrtc video chat application. It works fine on Debug build and doesn't crash but crashes on Release Build. My Webrtc version is

implementation 'org.webrtc:google-webrtc:1.0.27771'

Whenever I call this function I get error

# Fatal error in: ../../../../usr/local/google/home/sakal/code/webrtc-aar-release/src/sdk/android/src/jni/jni_generator_helper.cc, line 59

And this is where it crashes,

    public void start() {

        if (Nammu.checkPermission(CAMERA)) {

            //NEW
            PeerConnectionFactory.InitializationOptions initializationOptions =
                    PeerConnectionFactory.InitializationOptions.builder(this)
                            //.setEnableVideoHwAcceleration(true)
                            .setEnableInternalTracer(true)
                            //.setFieldTrials("WebRTC-FlexFEC-03/Enabled/")
                            .createInitializationOptions();
            PeerConnectionFactory.initialize(initializationOptions);


            PeerConnectionFactory.Options options = new PeerConnectionFactory.Options();
            DefaultVideoEncoderFactory defaultVideoEncoderFactory = new DefaultVideoEncoderFactory(
                    rootEglBase.getEglBaseContext(),  /* enableIntelVp8Encoder */true,  /* enableH264HighProfile */false);
            DefaultVideoDecoderFactory defaultVideoDecoderFactory = new DefaultVideoDecoderFactory(rootEglBase.getEglBaseContext());


            //NEW
        peerConnectionFactory = PeerConnectionFactory.builder()
                .setOptions(options)
                .setVideoEncoderFactory(defaultVideoEncoderFactory)
                .setVideoDecoderFactory(defaultVideoDecoderFactory)
                .createPeerConnectionFactory();

            VideoCapturer videoCapturerAndroid;
            videoCapturerAndroid = createCameraCapturer(new Camera1Enumerator(false));


            audioConstraints = new MediaConstraints();
            videoConstraints = new MediaConstraints();
            sdpConstraints = new MediaConstraints();

            if (videoCapturerAndroid != null) {

                //NEW
            SurfaceTextureHelper surfaceTextureHelper = SurfaceTextureHelper.create("CaptureThread", rootEglBase.getEglBaseContext());
            videoSource = peerConnectionFactory.createVideoSource(videoCapturerAndroid.isScreencast());
            videoCapturerAndroid.initialize(surfaceTextureHelper, getApplicationContext(), videoSource.getCapturerObserver());

            }
            localVideoTrack = peerConnectionFactory.createVideoTrack("100", videoSource);

            //create an AudioSource instance
            audioSource = peerConnectionFactory.createAudioSource(audioConstraints);

            localAudioTrack = peerConnectionFactory.createAudioTrack("101", audioSource);
            localAudioTrack.setEnabled(true);
            localAudioTrack.setVolume(1);

            if (videoCapturerAndroid != null) {
                videoCapturerAndroid.startCapture(1024, 720, 30);
            }

            localVideoTrack.addSink(localVideoView);

            localVideoView.setMirror(true);
            remoteVideoView.setMirror(true);

            gotUserMedia = true;
            if (SignallingClient.getInstance().isInitiator) {
                onTryToStart();
            }
        }else {
            Nammu.askForPermission(this, CAMERA, permissionCameraCallback);
        }
    }

Solution

I have solved this problem. It was happening due to progurd issue. simply putting

        release {
            consumerProguardFiles 'proguard-project.txt'
        }

solved my problem. Also this git repo might help.

    }

Answer 2

I was having the same problem and the solution was

Add file proguard-rules.pro to the app folder

## WebRTC
-keep class com.cloudwebrtc.webrtc.** { *; }
-keep class org.webrtc.** { *; }

and in build.gradle, add below 2 properties to buildTypes -> release

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
