Okay, that means a setting is needed.

For Render-Reconfiguration: It happens infact after we receive the first frame from decoder. If you don't switch refreshrates and play a file with the resolution matching the renderer it should not reconfigure. Though, do you mean: Firetv4K works with exoplayer? Anything you see in adb log?

Yes it works with ExoPlayer, just not Kodi.
Not sure which adb logs that would be, I've only done some logs using logcat which are here: https://github.com/xbmc/xbmc/issues/1889...-739099349

Okay. Looks like the demuxer needs more work. It might throw away stuff that it thinks it does not need. From the logs (decoder or render) both look equal shitty with lots of errors ...
