While we wait for this to be an actual feature I created a script that goes through your mux URLs and adds variables to them. Specifically for piping to ffmpeg to stop those pesky stalls. cit: https://tvheadend.org/d/5282-iptv-buffering-stalls-general-drop-outs-settings-that-resolved-things-for-me/50
It has a little retry logic built in and gives you a status of each mux afterwards. Hope this helps someone 🙂
