Ubuntu – How to play webm (using the VP9 codec) in VLC

codecsvlc

When I play a .webm file using the VP9 codec in VLC, I get the following error message (and the audio is played):

VLC does not support the audio or video format "VP90". Unfortunately
there is no way for you to fix this.

I can play these files in totem, but how can I play them in VLC?

I'm on Ubuntu 14.04 and VLC is 2.1.6. The package ubuntu-restricted-extras is installed.

VP9 requires VLC 2.2.

sudo add-apt-repository ppa:mc3man/trusty-media

sudo apt-get update

sudo apt-get install vlc vlc-plugin-*

I had this problem in ubuntu 14.04 and it got solved by installing VLC 2.2.

My solution was to go to Tools > Preferences in VLC and, in the Video tab:

Then Save your changes. That may fix the problem.

This command in a terminal should do:

sudo apt install ubuntu-restricted-extras

(As already explained by David Foerster, but this should be an answer, not a comment.)
