As the current version of the HTSP plugin for VLC does not work with VLC 3.0 libraries, I released a fixed version of the official plugin on GitHub: https://github.com/ThomasLeister/vlc-htsp-plugin/
For compilation, set up a basic make environment with g++ and the VLC development libraries, download the fixed source code and enter „make“:
sudo dnf install gcc-c++ vlc-devel libatomic wget https://github.com/ThomasLeister/vlc-htsp-plugin/archive/master.zip unzip master.zip cd vlc-htsp-plugin-master make
(Package installation according to Fedora’s dnf)
After successful compilation you can copy libhtsp_plugin.so to /lib64/vlc/plugins/access/ and start up VLC to setup the plugin.
sudo cp libhtsp_plugin.so /lib64/vlc/plugins/access/
