  9 mars 2017, par Furqan

  I am very new to FFMPEG library and i want some directions to implement a program that receives an list of videos (mp4 format) and audio file (mp3 ) and concatenate them with timestamps and remove its audio and add given audio and output a final video.

• FFMPEG Concat different video types along with Images and Gifs [duplicate]

  7 août 2020, par Philban

  So I thinking this question has been done to death but none of the solutions seem to work for me exactly.

  


  So TL ;DR here's what I'm looking to do.

  


  I have 3 video files all .mp4 at different scales and I would like to concat them all into a single .mp4. Now want to use the concat protocol and I know they need to be all the same scale.

  


  On top of that, I have 3 images (2 Gif's and 1 JPG) I'd like to have a final output video which looks like the following :

  


  

  • Image 1

  


  • Video 1

  


  • Gif 1

  


  • Video 2

  


  • Gif 2

  


  


  Could someone help me here and show me a command that I can run that works. Oh and lastly is it possible to keep the audio working from Video 1 and Video 2 ?

  


  Many thanks !!!

  


• 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 }

    '/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 }

  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).
