Is there any way to control Youtube through the media keys on the keyboard?

Solution 1:

This extension worked for me:

Global hotkeys for your favourite music players.

Control players inside Chrome from anywhere on your computer.

Source Streamkeys

I am using it on Last.fm

Update: Google removed it from the store.

Update: Back in the google store.

More info and how to download: github.com/berrberr/streamkeys/issues/416

Here is a link to zipped extension: https://drive.google.com/file/d/1T4VdEpbUzZO_FNe7OCOEO1Ac8SEZceBn/view?usp=sharing

You can use load unpacked extension button on chrome://extensions page in developer mode to add.

Solution 2:

Chrome 73 does it out of box.

Some people may even want to disable it at chrome://flags/#hardware-media-key-handling (source).
