• Why is "ffmpeg : command not found" in heroku, even with proper buildpack/config ?

  14 novembre 2022, par Jim

  In a node.js app hosted on heroku, ffmpeg is used by spawning processes, but is throwing errors anytime an ffmpeg command runs

  


  the error ffmpeg: command not found is thrown both in cli test heroku run ffmpeg as well as production logs

  


  Ive considered :

  


  

  • buildpack order

  


  • buildpack clearing/re-adding/redeploying

  


  • buildpack required env vars

  


  • heroku-stack-20 conflicts with buildpack#1 somehow ?

  


  


  Buildpack order :

  


  

  1. https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git

  


  2. https://github.com/heroku/heroku-buildpack-awscli.git

  


  3. https://github.com/timanovsky/subdir-heroku-buildpack.git

  


  4. heroku/nodejs

  


  


  Buildpack configs - from watching build logs, even though i havent set ffmpeg path, a default is found.

  


  beginning build logs (completes successfully, runs successfully - minus ffmpeg) :

  Any suggestions to further debug this ?

  


• Input format "highpass=f=300, is not available fluent ffmpeg npm

  24 juin 2022, par Sunil Garg

  I am using [fluent-ffmpeg][1] package to convert mp3 to wav. I have installed ffmpeg on my machine as well.

  


  Now in nodejs, I am trying following commands with options

  


  ffmpeg(mp3FilePath)
  .inputOptions([
      '-af', '"highpass=f=300, lowpass=f=3400"',
      '-r', '8000',
      '-ac', '1'
  ])
  .output(wavFilePath)
  .on('error', (err) => {
      console.log('An error occurred: ' + err.message);
      res.json("failed");
   })
   .on('progress', (progress) => {
      // console.log(JSON.stringify(progress));
      console.log('Processing: ' + progress.targetSize + ' KB converted');
   })
   .on('end', () => {
      console.log('Processing finished !');
      res.json("done");
   }).run();


  


  but this throws error

  


  An error occurred: ffmpeg exited with code 1: lowpass=f=3400": Invalid argument


  


  I am not able to figure out what is the problem. Any help ?

• FFmpeg's common filter "v360" missing

  26 septembre 2021, par Niklas E.

  I'm trying to convert a 180° fisheye video to a normal/regular video using the v360 filter of FFmpeg.

  


  This is the command I tried :
  
ffmpeg -i in.mp4 -vf "v360=input=fisheye:output=flat:iv_fov=180:v_fov=90" out.mp4

  


  But the output says clearly No such filter: 'v360', although v360 is a common filter listed in docs and other filters I used before worked just fine. I tried updating/reinstalling and looking for solutions, not fixing it.

  


  Why is the filter missing ? How can I debug this ? Should I doe the task using another program entirely ?

  


  Command output :
