• why ffmpeg is not working in new installation

  3 août 2013, par Hitesh Gupta

  I was working on live encoding from FFmpeg from last few days. One day I re-installed my OS and tried to run FFmpeg commands again after configuration. My publish points get in starting but could not started. Why ? Am I missing any configuration required ?

  The command I am trying to run is :

  ffmpeg -y -re -i D:\video2.mp4 -pix_fmt yuv420p -movflags isml+frag_keyframe -f ismv -threads 0 -c:v libx264 -preset fast -profile:v baseline -map 0:v -b:v:0 800k http://localhost/PPS/PublishPoint.isml/Streams(Encode
  
  r1)

  Output what I got in command prompt is :

• ffmpeg installation on macOS for MoviePy fails with SSL error

  26 juillet 2018, par shmible

  I’m trying to write a Python program that uses MoviePy on Mac OS 10.11.16 to convert an MP4 file to GIF. I use :

  import moviepy.editor as mp

  and I get an error saying I need to call imageio.plugins.ffmpeg.download() so I can download ffmpeg. I use :

  import imageio
  
  imageio.plugins.ffmpeg.download()

  which gives me the following error :

  Imageio: 'ffmpeg.osx' was not found on your computer; downloading it now.
  
  Error while fetching file: <urlopen error="error" certificate="certificate" verify="verify" failed="failed">.
  
  Error while fetching file: <urlopen error="error" certificate="certificate" verify="verify" failed="failed">.

  OSError: Unable to download 'ffmpeg.osx'. Perhaps there is a no internet connection? If there is, please report this problem.
  
  </module></urlopen></urlopen></urlopen></urlopen>

  I definitely have an internet connection. I found this link, and tried installing with Homebrew and Static builds, but neither have worked. It seems like compiling it myself would be a little too advanced for me (I’ve only briefly looked into it). I used imageio.plugins.ffmpeg.download() on IDLE. I read something about using PyCharm to run the MoviePy code, but I get the same initial error. ffmpeg is currently in my /usr/local/bin folder. Any suggestions are welcome. Thank for your help.

  Edit : I’m using Python 3.6.1
