SimpleExoPlayer.setVideoListener() causes rendering issues r2.1.1

Setting SimpleExoPlayer.VideoListener() causes rendering issues (SimpleExoPlayerView does not show any frames). audio plays fine and even the VideoListener's are invoked properly. Am I missing something here?
Following code illustrates the problem.

   private void playStream(final Uri mediaUrl) {
        Log.d(LOGTAG, "Now playing: " + mediaUrl);
        mUrl.setText(mediaUrl.toString());
        // Measures bandwidth during playback. Can be null if not required.
        DefaultBandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
        // Produces DataSource instances through which media data is loaded.
        DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this, Util.getUserAgent(this, "yourApplicationName"), bandwidthMeter);
        // Produces Extractor instances for parsing the media data.
        ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
        // This is the MediaSource representing the media to be played.
        MediaSource videoSource;
        if(mediaUrl.getLastPathSegment().contains(".m3u8"))
            videoSource = new HlsMediaSource(mediaUrl,dataSourceFactory, 10, null, null);
        else
            videoSource = new ExtractorMediaSource(mediaUrl,dataSourceFactory, extractorsFactory, null, null);
        // Following listener breaks rendering
        player.setVideoListener(new SimpleExoPlayer.VideoListener() {
            @Override
            public void onVideoSizeChanged(int width, int height, int unappliedRotationDegrees, float pixelWidthHeightRatio) {
                Log.e(LOGTAG, "onVideoSizeChanged: " + width + ":" +height);
            }

            @Override
            public void onRenderedFirstFrame() {
                Log.e(LOGTAG, "onRenderedFirstFrame ");
            }
        });
        // Prepare the player with the source.
        player.prepare(videoSource);
        player.setPlayWhenReady(true);
    }

Replacing setVideoListener() with setVideoDebugListener() solves the issue.
Tested on Nexus 9 running 7.0

SimpleExoPlayerView registers itself as the video listener, so when you set it you're replacing SimpleExoPlayerView as the listener. Hence SimpleExoPlayerView doesn't receive the events that it needs.

Why do you need to register a video listener when also using SimpleExoPlayerView?

Thank you so much for clarification, I will create my own SurfaceView and Controller instances.
I need the information for gathering QOS statistics.
I'll close this, thanks again for the quick response!

You should use setVideoDebugListener to gather QOS statistics, and let the view use setVideoListener.
