This URL works perfect if I open in VLC anytime, even after days, so that token is not temporary. If you try to play the stream without the token, it displays a video that it is not allowed.
In TvHeadEnd, it does not work with or without the parameter, it always shows the "not allowed" video
I tried with A/V Library on and off. I tried putting the "token=350bc152fa42a768e0ed4e233337d520"in Custom HTTP headers:
Passing parameters to IPTV stream in TvHeadend mux?
