Android:VideoCaptureThread上的webRtc崩溃

我在安卓系统中使用

webrtc

实现了视频通话，但我有这样的想法。它不是所有时候都产生的，只有在应用程序中有多个用户会话时才会产生

FATAL EXCEPTION: VideoCapturerThread

这是我的密码

 private VideoCapturer createCameraCapturer(CameraEnumerator enumerator) {
        final String[] deviceNames = enumerator.getDeviceNames();
        // First, try to find front facing camera
        Logging.d(TAG, "Looking for front facing cameras.");
        for (String deviceName : deviceNames) {
            if (enumerator.isFrontFacing(deviceName)) {
                Logging.d(TAG, "Creating front facing camera capturer.");

                VideoCapturer videoCapturer = enumerator.createCapturer(deviceName, null);
                if (videoCapturer != null) {
                    return videoCapturer;
                }
            }
        }
        // Front facing camera not found, try something else
        Logging.d(TAG, "Looking for other cameras.");
        for (String deviceName : deviceNames) {
            if (!enumerator.isFrontFacing(deviceName)) {
                Logging.d(TAG, "Creating other camera capturer.");
                VideoCapturer videoCapturer = enumerator.createCapturer(deviceName, null);
                if (videoCapturer != null) {
                    return videoCapturer;
                }
            }
        }
        return null;
    }

如何修复此问题？

当会话中的用户数发生变化时，尝试重新创建视频源。在创建

videoSource=peerConnectionFactory.createVideoSource（videoCapturerAndroid）之前添加以下代码

希望有帮助。
您是否在主线程以外的其他线程上调用此代码？
if(videoCapturerAndroid!=null) {
                    try {
                        videoCapturerAndroid.stopCapture();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }catch (Exception e) {
                        e.printStackTrace();
                    }
                    videoCapturerAndroid = createVideoCapturer(isFrontCamera);

                }
