Yes, that's how it works. VLC 3.07.1 64 bit and https://derste247livede.akamaized.net/hls/live/658317/daserste_de/master.m3u8
This combination works on my system.
So I can finally watch "Wer weiß denn sowas" on VLC.
Thank you.
I tested successful the following Streams from the Playlist above with the VLC-Player 3.0.8 (64-Bit) under Windows 7 (64-Bit).
