@vimple in case people need to do it from console:
Open terminal / ssh
cd /home/USERNAME/Downloads (or where you want download it to)
wget https://launchpad.net/~canonical-chromium-builds/+archive/ubuntu/stage/+build/15115081/+files/chromium-codecs-ffmpeg-extra_67.0.3396.99-0ubuntu0.16.04.2_amd64.deb
sudo dpkg -i chromium-codecs-ffmpeg-extra_67.0.3396.99-0ubuntu0.16.04.2_amd64.deb
