That could be the problem if you are seeing network request errors.

hls.js:6462 [log] > [level-controller]: live playlist 3 MISSED

The logs show that the live playlist is not updating (MISSED indicates that nothing changed since the last playlist refresh).

Hello, @robwalch

I will be closing this issue. My project runs in a WebView on an Android TV. The problem was resolved once my Android development colleague commented out the line setBuiltInZoomControls(false). However, I still don't understand why this is related to HLS playback. My video source is not problematic, as it plays correctly both on a regular web browser and in VLC media player. Do you have any idea why this might be the case? If so, please let me know. Thank you!
