  • Unable to install ffmpeg on CircleCi 2.0

    16 novembre 2017, par Mateusz Urbański

    I have Ruby on Rails project which uses CircleCi to run tests. In the past I was using CircleCi 1.0 but now I migrated to CircleCi 2.0. I have problem with installing ffmpeg. CircleCi 2.0 uses Ubuntu 14.04. I install ffmpeg like this :

    # ffmpeg installation
    
sudo add-apt-repository ppa:mc3man/trusty-media -y
    
sudo apt-get update
    
sudo apt-get install ffmpeg

    and my circle.yml config file looks like this :
