在MediaPlayer.prepare之后将TextureView应用于MediaPlayer会导致黑屏

Question

I'd like to switch the video method in MediaPlayer to TextureView 's Surface at some point during playback. But all I get is a black screen (the sound is playing). I made sure the size of the TextureView is ok, so it's not the case.

If I set the Surface of TextureView before calling prepare on MediaPlayer , than the video is shown.

So it seems that the order of calling prepare and applying the surface is crucial.

What's interesting, in case of SurfaceView everything works fine (no matter when I set the holder of SurfaceView : before or after the preparing is done).

Is there a way to set TextureView to MediaPlayer during playback? Calling MediaPlayer.release() and recreating it again while having to take care of progress would be very inconvenient.

@Override
    public void onSurfaceTextureAvailable(final SurfaceTexture surface, final int width, final int height) {
        s = new Surface(surface);
            Thread play = new Thread(new Runnable() {
                @Override
                public void run() {
                    try {

                        player = new MediaPlayer();
                        player.setSurface(s);
                        player.setDataSource(vidAddress);
                        player.prepare();
                        player.setOnPreparedListener(MainActivity.this);
                        player.setAudioStreamType(AudioManager.STREAM_MUSIC);
                        player.setOnCompletionListener(MainActivity.this);
                        player.setScreenOnWhilePlaying(true);

                        Log.e("mediaplayer", "true");
                    } catch (IllegalArgumentException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (SecurityException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IllegalStateException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            });
            play.start();

        }

And your onPrepared listener like this

public void onPrepared(MediaPlayer mp) {
        if (!player.isPlaying()) {
            player.start();     
        }
}

setSurfaceTextureListener like this at onCreate

mTextureView.setSurfaceTextureListener(MainActivity.this);

I hope this will help :)
