Rotating an android VideoView

My application offers only Portrait mode. In a portrait activity I have a fullscreen VideoView. What I want to do is rotate the VideoView ( the actual video, videobuffer) 90 degrees at Landscape mode. Enabling activity to be on Lanscape mode is not an option. Extending VideoView and canvas rotate will not work as it is a SurfaceView not an actual view. Is there any way to achieve that with a videoView?

Can I rotate a video on Android?

Choose Videos, then select the video you want to rotate. Tap the slider bar icon (it's at the bottom of the screen in the middle). Select Rotate until the video is oriented the way you want it. Choose Save.

How do I manually rotate my Android screen?

1 Swipe down the screen to access your Quick Settings and tap on Auto Rotate, Portrait or Landscape to change your screen rotation settings. 2 By selecting Auto Rotate,you will easily be able to switch between Portrait and Landscape mode. 3 If you choose Portrait this will lock the screen from rotating to landscape.

VideoView does not support rotation of video even if composition matrix is set correctly and rotation attribute is used.

What you can do is to use TextureView and set its attribute rotation="90" (for example). It then will rotate the frames but the aspect ratio is something that you need to handle your self. In order to do so you can use textureView.setScaleX((screenHeight * 1.0f) / screenWidth)

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextureView
        android:id="@+id/playback_video"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true"
        android:rotation="90" />
</RelativeLayout>

It should handle streamed video too. But please think of it as of an example rather than release ready code. I renamed some things and removed others, they don't have relation to the question and this might break something but in general this is workable example.

public class PlaybackActivity extends Activity implements MediaPlayer.OnErrorListener, OnPreparedListener,
        OnCompletionListener, OnVideoSizeChangedListener, OnBufferingUpdateListener, OnInfoListener,
        SurfaceTextureListener
{

    private MediaPlayer mediaPlayer;
    private TextureView videoView;
    private boolean startedPlayback = false;
    private boolean playerReady = false;
    public static final int MEDIA_INFO_NETWORK_BANDWIDTH = 703;

    private void createMediaPlayer() {
        mediaPlayer = new MediaPlayer();
    }

    private void releaseMediaPlayer() {
        if (mediaPlayer != null) {
            mediaPlayer.setSurface(null);
            mediaPlayer.release();
            mediaPlayer = null;
        }
    }

    public void onCompletion(MediaPlayer mp) {
        Log.w(TAG, "Video playback finished");
    }

    @Override
    public boolean onError(MediaPlayer player, int what, int extra) {
        if (what == MediaPlayer.MEDIA_ERROR_UNKNOWN) {
            /*
             * Restart play back in case we did not start anything yet. This may
             * be the case when we tried to tune in in very first secs of the
             * broadcast when there is no data yet.
             */
            if (liveBroadcast && mediaPlayer != null && !mediaPlayer.isPlaying() && !startedPlayback) {
                if (checkCount-- > 0) {
                    mediaPlayer.reset();
                    checkBroadcast();
                } else {

    }
}

Hope this helps. I was looking for this solution for quite long time. Tried almost everything and this seems to be the only way.

VideoView does not support rotation

you can use

<com.warnyul.android.widget.FastVideoView
        android:rotation="45"
        android:layout_above="@+id/controller"
        android:id="@+id/video2"
        android:foregroundGravity="center"
        android:layout_centerHorizontal="true"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

and must add bellow line to your dependencies in gradle

implementation 'com.warnyul.android.fast-video-view:fast-video-view:1.0.2'
