App crashed when I use exoplayer #3071

psedoykin · 2017-07-16T15:24:48Z

Hello,
I use exoplayer for playing radio from some internet stream.
I have implemented that user can change radio from app. (using viewpager)
For it I use the following code:

Create and init exoplayer

 private void createMediaPlayerIfNeeded() {
        Log.d(TAG, "createMediaPlayerIfNeeded");
        if (mPlayer == null) {
            Log.d(TAG, "createMediaPlayerIfNeeded: mPlayer != null");
            LoadControl loadControl = new DefaultLoadControl(new DefaultAllocator(true, C.DEFAULT_BUFFER_SEGMENT_SIZE), DEFAULT_MIN_BUFFER_MS,
                    DEFAULT_MAX_BUFFER_MS, DEFAULT_BUFFER_FOR_PLAYBACK_MS, DEFAULT_BUFFER_FOR_PLAYBACK_AFTER_REBUFFER_MS);

            DefaultRenderersFactory renderersFactory = new DefaultRenderersFactory(mContext);

            TrackSelection.Factory videoTrackSelectionFactory =
                    new AdaptiveTrackSelection.Factory(BANDWIDTH_METER);
            TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);

            mPlayer = ExoPlayerFactory.newSimpleInstance(renderersFactory,
                    trackSelector,
                    loadControl);

            mPlayer.setAudioStreamType(C.STREAM_TYPE_MUSIC);
            mPlayer.addListener(this);

            mPlayer.setAudioDebugListener(new AudioRendererEventListener() {
                @Override
                public void onAudioEnabled(DecoderCounters counters) {

                }

                @Override
                public void onAudioSessionId(int audioSessionId) {
                    if (mTypeAudio == PlaybackParams.TypeAudio.RADIO && mCallback != null) {
                        mCallback.onAudioSessionCreated(audioSessionId);
                    }
                }

                @Override
                public void onAudioDecoderInitialized(String decoderName, long initializedTimestampMs, long initializationDurationMs) {

                }

                @Override
                public void onAudioInputFormatChanged(Format format) {

                }

                @Override
                public void onAudioTrackUnderrun(int bufferSize, long bufferSizeMs, long elapsedSinceLastFeedMs) {

                }

                @Override
                public void onAudioDisabled(DecoderCounters counters) {

                }
            });
        } else {
            mPlayer.stop();
        }
    }

Start playing:

    private void play(Uri uri) {

        Log.d(TAG, "play(Uri uri)");

        tryToGetAudioFocus();

        DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(mContext,
                Util.getUserAgent(mContext, "mediaPlayerSample"));

        ExtractorMediaSource mediaSource = new ExtractorMediaSource(uri,
                dataSourceFactory,
                new DefaultExtractorsFactory(),
                null,
                null);

        mPlayer.prepare(mediaSource);
        mPlayer.setPlayWhenReady(true);
    }

When I change the radio very quickly from applications, it crashes and the application falls.
I cannot find why.
Could you help me with the issue ?
How can I enble some logs for exoplayer ?
Or may be I incorrect use mediaSource for exoplayer?

Please look at some logs for the issue:

Issue description

Some crash is occured when I quickly change mediaSource for exoplayer.
I cannot find why.
Looks like SimpleExoPlayer incorrect work when I stop it and change mediaSource and start again.

Reproduction steps

init exoplayer

   private void createMediaPlayerIfNeeded() {
        Log.d(TAG, "createMediaPlayerIfNeeded");
        if (mPlayer == null) {
            Log.d(TAG, "createMediaPlayerIfNeeded: mPlayer != null");

                    DEFAULT_MAX_BUFFER_MS, DEFAULT_BUFFER_FOR_PLAYBACK_MS, DEFAULT_BUFFER_FOR_PLAYBACK_AFTER_REBUFFER_MS);

                    new AdaptiveTrackSelection.Factory(BANDWIDTH_METER);
            TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);

            mPlayer = ExoPlayerFactory.newSimpleInstance(renderersFactory,
                    trackSelector,
                    loadControl);

            mPlayer.setAudioStreamType(C.STREAM_TYPE_MUSIC);
            mPlayer.addListener(this);

            mPlayer.setAudioDebugListener(new AudioRendererEventListener() {

                    if (mTypeAudio == PlaybackParams.TypeAudio.RADIO && mCallback != null) {
                        mCallback.onAudioSessionCreated(audioSessionId);
                    }
                }

                @Override

                null);

        mPlayer.prepare(mediaSource);
        mPlayer.setPlayWhenReady(true);
    }

Quickly change mediaSource for exoplayer

The attached bug report doesn't seem to include the segmentation fault above. Please could you provide a bug report taken just after reproducing the issue?

psedoykin · 2017-07-24T11:26:34Z

The issue is very hard reproduce. I will share bug report when reproduce the issue.

psedoykin · 2017-07-24T18:29:58Z

@andrewlewis please look at the report:
log2.txt

andrewlewis · 2017-08-02T15:50:36Z

The segmentation fault in log2.txt is in MediaCodec, so you may be able to work around this by returning false from MediaCodecUtil.isCodecUsableDecoder when the codec name is "OMX.MTK.AUDIO.DECODER.MP3", assuming the device has another working MP3 decoder. If that avoids the crashes let us know so we can submit a device-specific workaround. The other crashes pasted above are in AudioTrack not MediaCodec, so this probably won't help with those.

I don't think any of these crashes is caused by ExoPlayer, so please follow up directly with Huawei to get them to fix these device-specific issues. You could also see if any system updates are available for the device.
