Playback error on LiveTV in browser

[entireplant]

As title says, playback of livetv streams fails in browser (and on mobile and on another device) but works on an Nvidia Shield via the Android app (and directly, outside of jellyfin, via kodi). Turned on debug logging for Jellyfin but I can't seem to understand what's going on. I'm running in the jellyfin/jellyfin docker and using Intel QSV via an Arc A380. Main log, three ffmpeg logs and the console output of the browser included. Any help would be greatly appreciated. 

In the log I started the container, pressed play on the channel in chrome then stopped the container.
