The live stream of Spanish national public broadcaster RTVE can be watched using one of the following directions (both are probably geo-blocked):
https://ztnr.rtve.es/ztnr/1688885.m3u8
https://rtvelivestream.rtve.es/rtvesec/la2/la2_main_dvr.m3u8
When watching them directly within VLC Player, several subtitles are available (spanish, catalan etc.).
But if I pipe the m3u using a iptv network into TVHeadend, I can start a stream and VLC Player opens and plays audio and video, but no subtitles are available.
I already tried several slightly different configurations (see below), no one works.
Subtitles of our national broadcasters which I receive via satellite are working, so generally subtitles seem do work in my TVHeadend configuration, it's just the playlists of these spanish channels causing problems.
Normally I am using the 'pass'-profile, I tried the 'matroska'-profile, hoping it may contain the subtitles, but it isn't working neither.
Any ideas?
