android - 视频 View 在android中旋转90度

Question

我想将视频旋转 90 度。

当前我旋转布局但无法播放视频。xml

<LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="horizontal"
        android:rotation="90" >

        <VideoView
            android:id="@+id/videoView"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />
    </LinearLayout>

Java

videoView = (VideoView) findViewById(R.id.videoView);

          final Uri videoUri = Uri.parse(
               Environment.getExternalStorageDirectory().getAbsolutePath()+"/UnoPlayList/restaurant_menu_pro_mkv.mkv");

       videoView.setVideoPath(Environment.getExternalStorageDirectory().getAbsolutePath()+"/UnoPlayList/restaurant_menu_pro_mkv.mkv");
       //videoView.setRotation(180);
    //  videoView.setVideoURI(videoUri);
      videoView.start();

有什么方法可以旋转视频。

使用 camera.setDisplayOrientation() 和 recorder.setOrientationHint() 方法在捕捉视频时旋转视频。

    camera = Camera.open();
    //Set preview with a 90° ortientation
    camera.setDisplayOrientation(90);
    camera.unlock();

    recorder = new recorder();
    recorder.setCamera(camera);
    recorder.setAudioSource(recorder.AudioSource.MIC);
    recorder.setVideoSource(recorder.VideoSource.CAMERA);
    recorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_720P));
    recorder.setPreviewDisplay(mPreview.getHolder().getSurface());
    recorder.setOutputFile(getOutputMediaFile(MEDIA_TYPE_VIDEO).toString());
    
    //Rotate video by 90 degree
    recorder.setOrientationHint(90);
