• How to install ffmpeg for ubuntu using command line ?

  14 mars 2017, par Cheng Jaycee Jiang

  A lit background...
  This is a piece of code in my Dockerfile. I want to deploy my app to google app engine. Somehow I couldn’t install ffmpeg.

  ENV VIRTUAL_ENV /env
  
  ENV PATH /env/bin:$PATH
  
  RUN apt-get install ffmpeg

  This is error log :

  E: Unable to locate package ffmpeg
  
  The command '/bin/sh -c apt-get install ffmpeg' returned a non-zero code: 100
  
  ERROR
  
  ERROR: build step "gcr.io/cloud-builders/docker@sha256:ef2e6744a171cfb0e8a0ef27f9b9a34970341bfc0c3d401afdeedca72292cf73" failed: exit status 100

  I found this but it didn’t work for me. It complained about add-apt-repository is not valid command.

  Anyone can help me with this ? Thanks !!!

• How can I install ffmpeg in python

  1er février 2017, par ismail yussuf

  I’m having a problem with downloading ffmpeg for python. It seems to me that no matter what I do it just doesn’t work.

  Btw ,sorry for the images but I still don’t know how to post my command prompt on here. So here is the error i’m getting.

  I’ve already tried "pip install ffmpeg-normalize" and when I do that I get this

  FYI I already downloaded imageio and that went totally fine. I even have the ffmpeg.py file in imageio. I also saw a suggestion to use "imageio.plugins.ffmpeg.download()", that didn’t help either.

  Does anyone know how I can install it properly ?

  Thanks
