Reproducible in the demo app?

Yes

Reproduction steps

Add the following code to onTracksChanged() in PlayerEventListener in PlayerActivity

  Log.d("ExoPlayerTunneling", String.format("isTunnelingEnabled=%b", player.isTunnelingEnabled()));
}

1. Open demo app
2. Play HLS > Apple 4x3 basic stream (TS). Not sure if all playbacks will crash, but this does.
