• How to Fix 'ffmpeg' is not recognized as an internal or external command, operable program or batch file issue ?

  3 avril 2019, par Schüler

  How to generate video thumbnail in nodejs, I have been following these tutorials to install ffmpeg https://www.wikihow.com/Install-FFmpeg-on-Windows

  Here is the code :

   var Name = req.file['filename'];
  
          Files[Name] = { //Create a new Entry in The Files Variable
  
              FileSize: req.file['size'],
  
              Data: "",
  
              Downloaded: 0
  
          }
  
          fs.open("Temp/" + Name, 'a', 0755, function(err, fd) {
  
              var inp = fs.createReadStream("Temp/" + Name);
  
              var out = fs.createWriteStream("Video/" + Name);
  
              exec("ffmpeg -i Video/" + Name + " -ss 01:30 -r 1 -an -vframes 1 -f mjpeg Video/" + Name + ".jpg", function(err, dd) {
  
                  if (err) {
  
                      console.log(err)
  
                  }
  
                  console.log('Done', {'Image' : 'Video/' + Name + '.jpg'});
  
              });
  
          })

  I have installed ffmpeg to my system

  C:\Windows\system32>ffmpeg -version

  But Still, I am getting this error "fmpeg is not recognized as an internal or external command, operable program or batch file "

• 'ffmpeg' is not recognized as an internal or external command in nodejs node-ffmpeg

  24 mars 2024, par Wai Yan Hein

  I am developing a Node.js application. First of all, I am just a beginner when it comes to Node.

  


  What I am doing in my application now is that I am trying to create the thumbnail JPEG file for my mp4 file. I have already tried many possible solutions. Now I am using this one - https://github.com/damianociarla/node-ffmpeg. I think this is the potential solution among all. I am getting the error when I generate the JPEG thumbnail of the video file.

  


  Here is what I have done so far. I installed the package running this command

  


  npm install ffmpeg --save


  


  Then I try to generate the thumbnail files like this

  


  var ffmpeg = require('ffmpeg');
module.exports.createVideoThumbnail = function(req, res)
{
    try {
        var process = new ffmpeg('public/lalaland.mp4');
        process.then(function (video) {
            
            video.fnExtractFrameToJPG('public', {
                frame_rate : 1,
                number : 5,
                file_name : 'my_frame_%t_%s'
            }, function (error, files) {
                if (!error)
                    console.log('Frames: ' + files);
                else
                    //This error message is displayed
                    console.log(error)
            });

        }, function (err) {
            console.log('Error: ' + err);
        });
    } catch (e) {
        console.log(e.code);
        console.log(e.msg);
    }
    res.json({ status : true , message: "Video thumbnail created. Hopefully" });
}


  


  When I run the code, it is throwing an error. I commented in the code where the error is thrown from.
This is the error message

  


  { Error: Command failed: ffmpeg -i public/lalaland.mp4 -r 1 -s 0x0 -aspect NaN:NaN -vframes 5 -filter_complex "scale=iw*sar:ih, pad=max(iw\,ih*(NaN/NaN)):ow/(NaN/NaN):(ow-iw)/2:(oh-ih)/2:black" public/my_frame_1518211962631_0x0_%d.jpg

  I installed the ffmg as well. You can see below it is an installed command on my laptop

  


  

  


  What is missing in my code ?

  


• FFmpeg is in Path, but running in the CMD results in "FFmpeg not recognized as internal or external command"

  FFmpeg is installed in C:\FFmpeg, and I put C:\FFmpeg\bin in the path. Does anyone know how to fix ?
  Thanks !
