• error when running "imageio.plugins.ffmpeg.download()"

  14 juin 2018, par Maryeveh

  I am trying to run the command imageio.plugins.ffmpeg.download() after installing moviepy and imageio and importing imageio without error.
  I keep getting the following error and cannot figure out the solution :

  Imageio: 'ffmpeg-osx-v3.2.4' was not found on your computer; downloading it now.

  I tried all the solutions I could think of or/and found online, including the ones described here ffmpeg installation on macOS for MoviePy fails with SSL error, but nothing helped.
  Does anyone found another solution ?

• How to fix "Unable to find a suitable output format for '/'" error in ffmpeg running with PHP [on hold]

  4 avril 2019, par C.Pietro

  I want to compress video on the server after the upload.
  I installed correctly ffmpeg and when i run from the command line

   ffmpeg -i input.mp4 -vcodec libx265 -crf 28 -vcodec h264 -acodec aac -strict -2 output.mp4

  it works !

  But if i run the same command from PHP with exec,

  class VideoCompress {
  
      function compress($path, $name){
  
          if (`which ffmpeg`) {
  
              exec("cd \"$path\";ffmpeg -i \"$name\" -vcodec libx265 -crf 28 -vcodec h264 -acodec aac -strict -2 \"bk_$name\" / 2>&1", $o);
  
              print_r8($o);
  
          }
  
      }
  
  }

  it fails and return this error

• Python FFMPEG Heroku|Remove audio from video with Byte to Byte. No web processes running Error on Heroku

  15 mai 2021, par samoel

  I'm trying to get a .mp4 file from an address and remove the sound from it.I also want the data sent to FFMPEG to be bytes and return the result in byte

  


  i tried different command for my code like using -movflags frag_keyframe+empty_moov.
When I run this code in Heroku and receive the log...
