Striemtrien is a graphical user interface to start mpv media player without having to download videos first. Just paste a URL of a page with a video in it to play it directly!
git clone https://git.fsfe.org/jvs/Striemtrien.git
sudo apt install mpv python3-gi python3-pip python3-setuptools python3-wheel
sudo -H pip3 install youtube-dl
Open the application, paste a link, click the button.
As the URL’s of streaming sites change often, Striemtrien requires an up-to-date youtube-dl script. The best way is to use pip as described above.
youtube-dl can be updated with pip easily:
sudo -H pip3 install -U youtube-dl
