I’ve seen other people using a Chromecast and an Android phone to play Youtube videos on their TV. I wanted to do the same thing but instead I wanted to use my laptop. It turns out this is pretty difficult without using Google Chrome. I have since come up with a system which works reasonably well.
I use Qutebrowser
as my web browser. I configured qutebrowser to pipe videos to VLC
using this keybinding in my ~/.qutebrowser/config.py:
config.bind(',m', 'hint --rapid links spawn open -a VLC.app {hint-url}')
This allows me to press ,m while on a youtube page which displays thumbnails for videos, then select a video, which opens VLC and plays the video. This gets rid of any adverts.
To pipe the video to my Chromecast I can use the menu bar in VLC to select “Playback” -> “Renderer”, then my Chromecast, which is listed as an option if both are on the same local network.
To adjust the volume on the chromecast I use go-cast from the terminal:
cast -name "CHROMECAST NAME" volume 0.6
