• How to build ffmpeg.js via provided Unix code in Cygwin ?

  30 juin 2020, par rusty grad

  I am trying to build ffmpeg.js and add it to my program in windows. Docker does not work on my version of windows. The creator provided how to build it in Unix on his github page as follows :

  


  sudo apt-get update
sudo apt-get install -y git python build-essential automake libtool pkg-config
cd ~
git clone https://github.com/emscripten-core/emsdk.git && cd emsdk
./emsdk install latest
./emsdk activate latest
source emsdk_env.sh
cd ~
git clone https://github.com/Kagami/ffmpeg.js.git --recurse-submodules && cd ffmpeg.js
make


  


  How do I execute this command in Cygwin, or is there an easier way to incorporate FFMPEG or a competitor into a simple javascript client side operation ? I just need to run audio concatenation, which i confirmed works in cmd with FFMPEG :

  


  ffmpeg -i "concat:input1.mp3|input2.mp3|input3.mp3" -acodec copy output.mp3


  


• ffprobe : restore reporting error code for failed inputs

  15 août 2022, par Gyan Doshi

  ffprobe : restore reporting error code for failed inputs
  c11fb46731 led to a regression whereby the return code for missing
  
  input or input probe is overridden by writer close return code and
  
  hence not conveyed in the exit code.

• ffmpeg exited with code 1 : Error configuring complex filters

  21 décembre 2015, par rycornell

  I am using the fluent-ffmpeg node package to merge videos. I am following the documentation exactly but I get the following error : Error: ffmpeg exited with code 1: Error configuring complex filters. Here is the code :

  ffmpeg('/videos/test/part1.mov')
  
    .input('/videos/test/part2.mov')
  
    .on('error', function(err) {
  
      console.log('An error occurred: ' + err.message);
  
    })
  
    .on('end', function() {
  
      console.log('Merging finished !');
  
    })
  
    .mergeToFile('videos/test/final.mp4', 'videos/test/tempDir');

  and here is the error output (I logged the command generated by fluent-ffmpeg to the console) :

  C:\Program Files\ffmpeg\bin\ffmpeg.exe [ '-formats' ] { captureStdout: true }
  
  C:\Program Files\ffmpeg\bin\ffmpeg.exe [ '-encoders' ] { captureStdout: true }
  
  C:\Program Files\ffmpeg\bin\ffmpeg.exe [ '-i',
  
    '/videos/test/part1.mov',
  
    '-i','/videos/test/part2.mov',
  
    '-y',
  
    '-filter_complex',
  
    'concat=n=2:v=1:a=1',
  
    'videos/test/final.mp4' ] { niceness: 0 }
  
  An error occurred: Error: ffmpeg exited with code 1: Error configuring complex filters.

  I’m able to run ffmpeg on my machine for other tasks and it works fine. I’m not sure what the ’-filter_complex’ flag is supposed to do. I am using fluent-ffmpeg version 2.0.1 and ffmpeg windows static build git-9d1fb9e (2015-12-17).
