• Ffmpeg error in Docker Container : ffmpeg exited with code 1 :

  2 octobre 2017, par Uğur Kaya

  I am currently working on a project and almost ready to deploy, but there is one problem : the code which is working perfectly on my Ubuntu 16.04 (Elementary OS Loki) machine does not work in Docker container. What might be the problem in my code ?

  Here is my Dockerfile :

  FROM beevelop/nodejs-python:latest
  
  
  
  RUN apt-get -y update && apt-get install -y libav-tools
  
  RUN ffmpeg --help
  
  
  
  # Global install yarn package manager
  
  RUN apt-get update && apt-get install -y curl apt-transport-https && \
  
      curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - && \
  
      echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list && \
  
      apt-get update && apt-get install -y yarn
  
  
  
  WORKDIR /app
  
  COPY package.json .
  
  RUN yarn
  
  COPY . .
  
  RUN yarn prod:build
  
  EXPOSE 8080
  
  CMD [ "yarn", "start" ]

  I run sudo docker exec -it  ffmpeg --help and it outputs the expected help print. In my code, I download a Youtube video in mp4 format with this code :

  const download = idParam => (
  
    new Promise((fulfill, reject) => {
  
      const id = `http://www.youtube.com/watch?v=${idParam}`
  
      let videoMeta
  
      youtubedl(id, ['--format=36'], { cwd: __dirname })
  
        .on('info', (info) => {
  
          const customDimensions = calculateCustomDimensions(info.format)
  
          videoMeta = { ...info, ...customDimensions }
  
        })
  
        .pipe(fs.createWriteStream(`temp/${idParam}.mp4`))
  
        .on('finish', () => {
  
          console.log('Dirname: ', __dirname)
  
          fulfill(videoMeta)
  
        })
  
        .on('error', (err) => {
  
          console.log('There is an error:', err)
  
          console.log('Dirname: ', __dirname)
  
          reject(err)
  
        })
  
    })
  
  )

  And then try to process the video with fluent-ffmpeg :

  const processVideo = (videoName, cropStart, cropEnd) => (
  
    new Promise((resolve, reject) => {
  
      try {
  
        console.log('Trying to run ffmpeg binary.')
  
        ffmpeg()
  
          .addInput(`temp/${videoName}.mp4`)
  
          .seekInput(cropStart)
  
          .duration(cropEnd)
  
          .outputOption('-movflags frag_keyframe+faststart')
  
          .on('end', () => {
  
            console.log('Processing has finished with ffmpeg. ')
  
            console.log('Resolved for upload: ', [`temp/cropped_${videoName}.mp4`, `temp/${videoName}.mp4`])
  
            console.log('Going out of processVideo script.')
  
            resolve([`temp/cropped_${videoName}.mp4`, `temp/${videoName}.mp4`])
  
          })
  
          .on('error', (err, stdout, stderr) => {
  
            console.log('Error. Output option olmasına rağmen: ', err.message)
  
            console.log('ffmpeg output:\n', stdout)
  
            console.log('ffmpeg stderr:\n', stderr)
  
          })
  
          .save(`temp/cropped_${videoName}.mp4`)
  
      } catch (e) {
  
        console.log('There has been an error while converting ffmpeg binary!')
  
        console.log(e.msg)
  
        console.log(e.code)
  
        reject(e)
  
      }
  
    })
  
  )

  It gives the following error :

• Unable to load FFProbe driver for FFmpeg

  12 septembre 2021, par Kapil Ropalekar

  Hi i am trying to install php-ffmpeg.
  Can someone guide me or correct me in my steps.

  



  


  1. I installed the composer on windows and then traversed to my folder i had created to run install ffmpeg cmd

  


  2. After running this command a composer.json, composer.lock file were created along with a vendor folder.

  


  3. Later installed the Shared FFMpeg build for 64bit from here

     



     


     http://ffmpeg.zeranoe.com/builds/

     


  


  



  and form this folder copied the bin folder to my directory to set the ffmpeg and ffprobe path during create() like this

  



  $ffmpeg = \FFMpeg\FFMpeg::create([
    'ffmpeg.binaries'  => '/vendor/bin/ffmpeg.exe',
    'ffprobe.binaries' => '/vendor/bin/ffprobe.exe' 
]);


  



  Currently i am getting this error which says :

  



  "Fatal error: Uncaught exception 'Alchemy\BinaryDriver\Exception\ExecutableNotFoundException' with message 'Executable not found, proposed : /vendor/bin/' in D:\xampp\htdocs\health\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\AbstractBinary.php:160 Stack trace: #0 D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Driver\FFProbeDriver.php(48): Alchemy\BinaryDriver\AbstractBinary::load('/vendor/bin/', NULL, Object(Alchemy\BinaryDriver\Configuration)) #1 D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe.php(207): FFMpeg\Driver\FFProbeDriver::create(Array, NULL) #2 D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFMpeg.php(117): FFMpeg\FFProbe::create(Array, NULL, NULL) #3 D:\xampp\htdocs\health\ff.php(6): FFMpeg\FFMpeg::create(Array) #4 {main} Next exception 'FFMpeg\Exception\ExecutableNotFoundException' with message 'Unable to load FFProbe' in D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Driver\FFProbeDriver.php:50 Stack trace: #0 D:\xampp\htdocs\he in D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Driver\FFProbeDriver.php on line 50".


  



  So what could i have done wrong or am i missing any steps. Can someone point me to the right direction.
