Nexus6 无法播放此视频

Question

我关注这个[示例][1] 是为了了解如何使用 Android 摄像机。

我的 activity 的代码只是一个按钮和一个 VideoView。点击按钮后我录制了一段视频，然后在停止录制后，录制的视频在 VideoView 上可见。该代码在 Galaxy S2(api16) 和华为 L21(api 22) 上完美运行，但在摩托罗拉 Nexus 6(api23) 上我遇到了这个错误

Can not play this video

这是我的 activity 文件：

public class MainActivity extends AppCompatActivity {

@Bind(R.id.button)
Button button;

@Bind(R.id.videoView)
VideoView videoView;

private Uri fileUri;
public static final int MEDIA_TYPE_VIDEO = 2;
private static final int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE = 200;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(this);
}

@OnClick(R.id.button)
protected void startRecording() {
    launchCamera();
}

private void launchCamera() {
    Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
    fileUri = getOutputMediaFileUri(MEDIA_TYPE_VIDEO);  // create a file to save the video
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);  // set the image file name
    // set the video image quality to high
   startActivityForResult(intent, CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE);
}

private  Uri getOutputMediaFileUri(int type) {
    Uri myUri =  Uri.fromFile(getOutputMediaFile(type));
    Log.d("TAG","uri we have is "+myUri);
    return myUri ;
}

private  File getOutputMediaFile(int type){

    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_MOVIES), "MyCameraApp");

    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            Log.d("MyCameraApp", "failed to create directory");
            return null;
        }
    }

    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    File mediaFile;

        mediaFile = new File(mediaStorageDir.getPath() + File.separator +
                "VID_"+ timeStamp + ".mp4");

    return mediaFile;
}


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            videoView.setVideoURI(fileUri);
            videoView.start();
}

}

以及我使用 Nexus6 获取的日志

知道为什么在 Nexus 6 上不起作用吗？

Answer 1

相机版应用升级至3.2.045后修复。这是相机应用程序本身的问题，而不是我发布的代码中的问题。
