Reproducible in the demo app?

Yes

Reproduction steps

1. Add .setCmcdConfigurationFactory(CmcdConfiguration.Factory.DEFAULT) in PlayerActivity#createMediaSourceFactory when creating the DefaultMediaSourceFactory
2. Add the following entry in media.exolist.json in the HLS samples array

      {
        "name": "Apple LL-HLS",
        "uri": "https://ll-hls-test.cdn-apple.com/llhls4/ll-hls-test-04/multi.m3u8"
      }

3. Launch demo app and select the Apple LL-HLS test stream

Expected result

Stream plays and CMCD data is reported.

Note: Worth mentioning that without CMCD the streams play without a problem.

Actual result

Playback fails and following error message is shown in Logcat

On another stream with LL-HLS + HEVC the following exception can be observed as well:
