Before filing an issue:

I run with video is local file ( not streamimng)

    ` Handler handler = new Handler() ;
  DefaultBandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
    TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
    TrackSelector trackSelector = new DefaultTrackSelector( videoTrackSelectionFactory);`

 player = ExoPlayerFactory.newSimpleInstance(mContext, trackSelector,new DefaultLoadControl());

   viewVideo.setUseController(false);

    viewVideo.setUseArtwork(true);

    viewVideo.requestFocus();

    viewVideo.setPlayer(player);

   MediaSource videoSource;

    LoopingMediaSource loopingMediaSource;

    MediaSource concatenatedSource = null;
    ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(mContext,
    Util.getUserAgent(mContext, mContext.getPackageName()), bandwidthMeter);

    Uri uri = Uri.parse(eachSource);
            videoSource = new ExtractorMediaSource(uri,
                        dataSourceFactory, extractorsFactory, handler, null);
    loopingMediaSource
                = new LoopingMediaSource(videoSource);
        player.prepare(loopingMediaSource);
        player.setPlayWhenReady(true);
       `

The original cause of failure (clipped off the top of what you've provided), is:

EventLogger: com.google.android.exoplayer2.ParserException: The edited sample sequence does not contain a sync sample.
EventLogger:    at com.google.android.exoplayer2.extractor.mp4.AtomParsers.parseStbl(AtomParsers.java:398)
EventLogger:    at com.google.android.exoplayer2.extractor.mp4.Mp4Extractor.processMoovAtom(Mp4Extractor.java:343)

It appears the problematic media has a strange edit list, that's discarding the first 4 video frames for no apparent reason. The first frame is the only key-frame, so after applying the edit list we end up with no key-frames from which to start playback.

Playing this type of media correctly is tracked by https://github.com/google/ExoPlayer/issues/1659, although there doesn't seem to be a valid reason for the edit list to exist in the piece of media. If you have control over the media itself then you should just fix it to not include an edit list.

Ok ,Could you please give me some information about edit list ?,( i have no idea what edit list do in mp4 file ) , before i exclude edit list form mp4 file.

ojw28 commented 7 years ago

Advising on correct media preparation is outside the scope of this issue tracker, sorry. I'd suggest asking on StackOverflow or similar.
