Question

我见过这样的问题，但我没有找到解决方案，所以这就是我问这个问题的原因。

当我在阿尔卡特手机上运行我的应用程序并开始视频录制时，一切似乎都很好，直到我按下停止按钮，然后我得到RuntimeException。我读到我的视频或音频状态不佳，但我无法弄清楚原因。

这是我的代码：

private boolean prepareMediaRecorder(String name) {

    if (isCameraOpened()) {
        stop();
        start();
    }

    mediaRecorder = new MediaRecorder();
    //int orientation = mCameraInfo.orientation;
    //int orientation = calcCameraRotation(mDisplayOrientation);
    int degrees = 0;
    switch (currentOrientation) {
        case Surface.ROTATION_0:
            degrees = 0;
            break;
        case Surface.ROTATION_90:
            degrees = 90;
            break;
        case Surface.ROTATION_180:
            degrees = 180;
            break;
        case Surface.ROTATION_270:
            degrees = 270;
            break;
    }

    int result;
    /*if (mCameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
        result = (360 - (mCameraInfo.orientation + degrees) % 360) % 360;
    } else {  // back-facing
        result = (mCameraInfo.orientation - degrees + 360) % 360;
    }*/
    if(mCameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_BACK) {
        result = (mCameraInfo.orientation - degrees + 360) % 360;
       // mediaRecorder.setOrientationHint(result);
        mediaRecorder.setOrientationHint(result);
    } else{
        result = (mCameraInfo.orientation + degrees) % 360;
        mediaRecorder.setOrientationHint(result);
    }
    Size pictureSize = null;

    SortedSet<Size> sizes = mPreviewSizes.sizes(mAspectRatio);
    if (sizes == null) { // Not supported
        mAspectRatio = chooseAspectRatio();
        sizes = mPreviewSizes.sizes(mAspectRatio);
    }

    mPictureSizes.clear();

    for (Camera.Size size : mCameraParameters.getSupportedVideoSizes()) {
        mPictureSizes.add(new Size(size.width, size.height));
    }

    Size size = chooseOptimalSize(sizes);

    final Camera.Size currentSize = mCameraParameters.getPictureSize();
    if (currentSize.width != size.getWidth() || currentSize.height != size.getHeight()) {
        // Largest picture size in this ratio
        pictureSize = mPictureSizes.sizes(mAspectRatio).last();
        if (mShowingPreview) {
            mCamera.stopPreview();
        }

        if(mCameraParameters.getSupportedPreviewSizes() != null) {
            mCameraParameters.setPreviewSize(size.getWidth(), size.getHeight());
        }

        setAutoFocusInternal(mAutoFocus);
        if(mFlash == 1){
            mCameraParameters.setFlashMode(Camera.Parameters.FLASH_MODE_TORCH);
        }
        mCamera.setParameters(mCameraParameters);
        if (mShowingPreview) {
            mCamera.startPreview();
        }
    } 

    mCamera.unlock();

    mediaRecorder.setCamera(mCamera);

    //Set source
    mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

    CamcorderProfile cpHigh = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
    mediaRecorder.setProfile(cpHigh);
    if(pictureSize != null) {
        mediaRecorder.setVideoSize(pictureSize.getWidth(), pictureSize.getHeight());
    }

    mediaRecorder.setOutputFile(name);


    try {
        mediaRecorder.prepare();
        ///mediaRecorder.start();

    } catch (IllegalStateException e) {
        releaseMediaRecorder();
        return false;
    } catch (IOException e) {
        releaseMediaRecorder();
        return false;
    }
    return true;

}

然后我在AsyncTask中启动MediaRecorder，这是我的停止方法。

@Override
void stopVideo() {
    if(mFlash == 1){
        mCameraParameters.setFlashMode(Camera.Parameters.FLASH_MODE_ON);
    }
    if(isVideoRecording == true) {
        try {
            mediaRecorder.stop();
            isVideoRecording = false;
            releaseMediaRecorder();
            getBackgroundHandler().post(new Runnable() {
                @Override
                public void run() {
                    File file = getFile(name);
                    if (file != null) {
                        ContentValues values = new ContentValues();
                        values.put(MediaStore.Video.Media.TITLE,  file.getName());
                        values.put(MediaStore.Video.Media.DESCRIPTION, "Taken by All Ears Selfie app");
                        values.put(MediaStore.Video.Media.DATE_TAKEN,   System.currentTimeMillis());
                        values.put(MediaStore.Video.Media.MIME_TYPE, "video/mp4");
                        values.put(MediaStore.Video.Media.SIZE,  file.length());
                        values.put("_data", file.getAbsolutePath());

                        ContentResolver cr = context.getContentResolver();
                         cr.insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values);

                    }
                }
            });
        } catch (RuntimeException e){
            Log.d("TAG", e.getMessage());
            File file = getFile(name);
            file.delete();
        }

    }

    if(isCameraOpened()){
        stop();
        start();
    }
}

编辑：我为Media Recorder添加了OnErrorListener，我收到此错误：268435556。
