Question

我正在开发一个实时流式Android应用程序。该应用程序将使用MediaRecorder在后台录制视频，我可以将其存储到SD卡。我正在尝试使用Wowza Media引擎来传输这段录制的视频，但视频没有传输。

surfaceView = new SurfaceView(this);
    LayoutParams layoutParams = new WindowManager.LayoutParams(1, 1,
            WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
            WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
            PixelFormat.TRANSLUCENT);
    layoutParams.gravity = Gravity.LEFT | Gravity.TOP;
    windowManager.addView(surfaceView, layoutParams);
    surfaceView.getHolder().addCallback(this);

@Override
public void surfaceCreated(SurfaceHolder surfaceHolder) {

    Camera.CameraInfo cameraInfo = new Camera.CameraInfo();
    int numberOfCameras = Camera.getNumberOfCameras();



    for (int i = 0; i < numberOfCameras; i++) {
        Camera.getCameraInfo(i, cameraInfo);
        if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
            camera = Camera.open(i);
        }

        if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_BACK) {
            // camera = Camera.open();
        }
    }

    mediaRecorder = new MediaRecorder();
    camera.unlock();

    mediaRecorder.setPreviewDisplay(surfaceHolder.getSurface());
    mediaRecorder.setCamera(camera);
    mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mediaRecorder.setProfile(CamcorderProfile
            .get(CamcorderProfile.QUALITY_HIGH));
    mediaRecorder.setOutputFile(Environment.getExternalStorageDirectory()
            + "/video_recording.mp4");

    mediaRecorder.setOrientationHint(270);
    try {
        mediaRecorder.prepare();
    } catch (Exception e) {
    }
    mediaRecorder.start();      

}

当我尝试使用RtspClient mClient传输此视频时出现此错误。请帮助我使用MediaRecoder录制的Wowza流式传输视频。以下是Wowza http://www.androidhive.info/2014/06/android-streaming-live-camera-video-to-web-page/

出于好奇，我可以问你为什么要在手机上录音？我第一次想到如何从Android实现实时流式传输是使用Wowza GoCoder mobile encoding app从您的Android手机直播，或者使用Intel INDE Media Pack for Android内置的核心GoCoder技术构建您的流媒体应用程序（如果适用）你的情况）。如果您已经在使用Wowza Streaming Engine，它还可以从实时流中为您录制，可能节省手机处理，内存和电池。
