I user exoplayer demo 2.9.6, and set playmode to Player.REPEAT_MODE_ALL,then i click YouTube Dash-->Google Glass (MP4,H264) ,then it play failed. Code and log are as follows. `player = ExoPlayerFactory.newSimpleInstance( / context= / this, renderersFactory, trackSelector, drmSessionManager); player.addListener(new PlayerEventListener()); player.setPlayWhenReady(startAutoPlay); player.setRepeatMode(Player.REPEAT_MODE_ALL); player.addAnalyticsListener(new EventLogger(trackSelector)); playerView.setPlayer(player); playerView.setPlaybackPreparer(this); debugViewHelper = new DebugTextViewHelper(player, debugTextView); debugViewHelper.start(); MediaSource[] mediaSources = new MediaSource[uris.length]; for (int i = 0; i < uris.length; i++) { mediaSources[i] = buildMediaSource(uris[i], extensions[i]); } mediaSource = mediaSources.length == 1 ? mediaSources[0] : new ConcatenatingMediaSource(mediaSources);

boolean haveStartPosition = startWindow != C.INDEX_UNSET; if (haveStartPosition) { player.seekTo(startWindow, startPosition); } player.prepare(mediaSource, !haveStartPosition, false); updateButtonVisibilities();`

log:

See also https://github.com/google/ExoPlayer/issues/5609 which affects the same device.

It seems this device has stability issues in the underlying platform. You will most likely need to report these to the device manufacturer.
