Video playback debug

We are using HTML5 Video player.
While certain HLS content is playing, the playback freezes forever. I need to debug playback in order to find the cause. What is the best way to do this? While playback is stopped, the player does not send any special events. The only thing. I see that player.buffered.end stops growing. Chrome DevTools Network also doesn’t show information about downloading .ts files. Is there some kind of debug mode for video playback?

Thank you.

We support the web inspector only. Please check Streaming Protocol and DRM. Some HLS tags are not supported in the webOS TV, and most issues are caused by the tags. Thank you.
