ExoPlayer 2.15.1 throws NoSuchElementException on loading Live LL HLS manifest

I’ll forward a link to the stream to the dev email, along with a bugreport.zip.

Reproducible in: ExoPlayer 2.15.1 demo ExoPlayer 2.13.0 demo Notable that the stream plays in the ExoPlayer 2.10.8 demo (although also noted that LL HLS support was not announced until 2.13.0, just noting here that it played without apparent problems in ExoPlayer 2.10.8).

Describe how the issue can be reproduced, ideally using the ExoPlayer demo app:

• Added the manifest URL (sent to the dev email) to the media.exolist.json file in the demo app
• Launch the demo app
• Select the asset from the list

Expected:

• When the player loads, the master and chunklist manifest requests are successful
• As with ExoPlayer 2.10.8, segments are then requested and can be played

Actual:

• When the player loads, the master and chunklist manifest requests are successful
• No segments are requested
• A NoSuchElementException is thrown, and playback does not start:

Thanks! I was able to play your stream.

Looks like gradle JDK needs to be to Java 11. You can configure this in File > Settings. Then search for gradle where you can select the JDK used by gradle.

The fix will land in the next release. I think this will happen approximately within the next two weeks or so.
