I know this question is about Linux  but in case someone stumbles on this problem on Mac like I did here is the solution for that  I had the exact same problem on Mac because ffmpeg is not installed by default apparently  and so I could solve it using   brew install yasm brew install ffmpeg

Had the same problem    managed to get it to work after a little while  Thing to do is follow instructions on installing FFmpeg - which is  at least on windows  a bundle of executables you need to set a path to in your environment variables http   www wikihow com Install-FFmpeg-on-Windows Download from ffmpeg org Hope this helps someone - even after a while after the question - good luck

I had the following error while running the cell    This may be due to not having ffmpeg in your system  Try the following command in your terminal   sudo apt install ffmpeg   This works for me  I hope it will work out for you too

For fellow googlers using Anaconda  install the ffmpeg package   conda install -c conda-forge ffmpeg   This works on Windows too    Original answer used menpo package owner but as mentioned by  harsh their version is a little behind at time of writing

If you are using Ubuntu 14 04 ffmpeg is not available  You can install it by using the instructions directly from https   www ffmpeg org download html    In short you will have to   sudo add-apt-repository ppa mc3man trusty-media sudo apt-get update sudo apt-get install ffmpeg gstreamer0 10-ffmpeg   If this does not work maybe try using sudo apt-get dist-upgrade but this may broke things in your system
