Exoplayer playback failed issue

See original GitHub issue

Our testers found a video file that was getting stuck when seeking to a particular position in the video.

I tested it against the demo application recommended in the template ( http://exoplayer.dev/demo-application.html). I modified the media.exolist.json to just my test file

[
  {
    "name": "Test",
    "samples": [
      {
        "name": "Test media",
        "uri": "file:///storage/emulated/0/Download/01_2x2.mp4"
      }
    ]
  }
]

The issue occurs when seeking to 0:30 in the video. Seeking anywhere else works correctly. The issue was also not reproducible in exoplayer-2.11.x. The media used can be found here:

I have attached a video where I was able to reproduce the bug:

I think this may be working as intended. Your file only has 4 keyframes at samples 0, 250, 500 and 750, which are about 130MB of data apart from each other. So if you seek to just before a keyframe the player needs to load data from the previous keyframe and eventually reaches its default memory limit of 131 MB without having enough media available for playback yet. This is what the exception is detecting. In 2.11. we forced loading more data in such case without any upper limit, that’s why you can’t reproduce in 2.11.

To solve this, you should ideally create the file with more keyframes if it has such a high bitrate, or increase the allowed memory limit in DefaultLoadControl.Builder.setTargetBufferBytes.

Sorry, I must have missed that!
