Playing back a certain MOV file through ExoPlayer will result in the playback being too fast.

The code to instantiate ExoPlayer is:

mediaPlayer = ExoPlayer.Factory.newInstance(2, 5000, 15000);

Allocator allocator = new DefaultAllocator(BUFFER_SEGMENT_SIZE);

TransferListener listener = new DefaultBandwidthMeter(uiHandler, (elapsedMs, bytes, bitrate)
        -> bandwidthSample.setText(String.format(Locale.getDefault(), "bitrate: %d kb/s", bitrate / 8 / 1000)));

DataSource dataSource = new DefaultUriDataSource(this, listener, "MyApp/1.0");

ExtractorSampleSource sampleSource = new ExtractorSampleSource(getIntent().getData(),
        dataSource, allocator, BUFFER_SEGMENT_COUNT * BUFFER_SEGMENT_SIZE, 5, new Handler(), (sourceId, e) -> {
    Log.e(TAG, "failed loading source: " + sourceId, e);
}, -1, new Mp4Extractor());

MediaCodecVideoTrackRenderer videoRenderer =
        new MediaCodecVideoTrackRenderer(this, sampleSource, MediaCodecSelector.DEFAULT,
                MediaCodec.VIDEO_SCALING_MODE_SCALE_TO_FIT, 0, new Handler(), new MediaCodecVideoTrackRenderer.EventListener() {
            @Override
            @DebugLog
            public void onDroppedFrames(int count, long elapsed) {

            }

            @Override
            @DebugLog
            public void onVideoSizeChanged(int width, int height, int unappliedRotationDegrees, float pixelWidthHeightRatio) {
                surfaceView.adjustToVideoSize(width, height);
            }

            @Override
            @DebugLog
            public void onDrawnToSurface(Surface surface) {

            }

            @Override
            @DebugLog
            public void onDecoderInitializationError(MediaCodecTrackRenderer.DecoderInitializationException e) {

            }

            @Override
            @DebugLog
            public void onCryptoError(MediaCodec.CryptoException e) {

            }

            @Override
            @DebugLog
            public void onDecoderInitialized(String decoderName, long elapsedRealtimeMs, long initializationDurationMs) {

            }
        }, -1);

MediaCodecAudioTrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(
        sampleSource, MediaCodecSelector.DEFAULT);

mediaPlayer.prepare(videoRenderer, audioRenderer);

mediaPlayer.addListener(new ExoPlayer.Listener() {
    @Override
    @DebugLog
    public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
        progressBar.setVisibility(playbackState == ExoPlayer.STATE_BUFFERING ? View.VISIBLE : View.GONE);
    }

    @Override
    @DebugLog
    public void onPlayWhenReadyCommitted() {

    }

    @Override
    @DebugLog
    public void onPlayerError(ExoPlaybackException error) {

    }
});

mediaPlayer.sendMessage(videoRenderer, MediaCodecVideoTrackRenderer.MSG_SET_SURFACE, holder.getSurface());

mediaPlayer.setPlayWhenReady(true);

Sample video has been sent over to dev.exoplayer..

The issue occurs on a Nexus 6, running Android 6.0.1. It also occurs on a Samsung S5, Android 6.0.1.

Exo Player version: d7b8256

Nothing crashes, therefore I can only offer adb logcat messages which occur during the playback:

This is an example of raw PCM audio in mp4. The audio samples end up with incorrect timestamps. The samples are rechunked, but it appears the timestamps are wrong even if rechunking is disabled.

@dcower - Could you take a look at this? It's quite possible that the audio timestamps are incorrect in the media itself, but it could be that we've missed something.

The audio stream does say something about pcm_s16le.

Playback using Androids MediaPlayer or VLC would work ok and on time.

Please also note the dropped frames, which in turn make the video playback stutter. (perhaps related to the audio problems).

@dcower has there been any progress on that for further testing? Thx

Closing this on the assumption the media was broken. If it was just the one file and you don't know how to generate a file that's similarly broken, this seems quite likely. If you're aware of a way to generate such files please let us know, and we'll take a closer look.

The file was streamed of a car DVR which contained a standard chip, built into millions of those devices. I can re-test using the latest firmware and models and will re-upload.
