• FFMPEG for aws s3 bucket signed url not working in node js

  21 août 2018, par ahmed sharief

  I am trying to create thumbnails from an amazon s3 bucket signed url. I am able to generate thumbnails when i run the command in terminal

  ffmpeg -ss 00:00:02 -i "https://test-s3-bucket.s3.ap-south-1.amazonaws.com/user_gallery_assets/5b6936069ac2bf0602085367/gallery/images/5b7be08527641dee8c1f8134.mp4?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=xxxxxxxxx%2F20180821%2Fap-south-1%2Fs3%2Faws4_request&X-Amz-Date=20180821T095101Z&X-Amz-Expires=900&X-Amz-Signature=d7f81f4eed3d6c87c04dc1b0ad06beeb946afa33d417585f57fad72aeadb3ac0&X-Amz-SignedHeaders=host" -vframes 1 -q:v 2 -f image2 output.jpg

  I am running the above command in terminal and its working fine but when i try to implement the same in node js its showing "no such file or directory error". Though i am encoding the url with double quotes then also its showign same error. Here is my node js code....

  function uploadThumbNailForVideo(obj,url, thumb_url){
  
      return new Promise((resolve, reject) => resolve(url))
  
      .then((url) => awsHelper.getImage(url))
  
      .then((result) => { 
  
  
  
          var resUrl = "\""+result+"\"";
  
  
  
          var args = [ 
  
              '-i', resUrl, 
  
              '-ss', '00:00:02', 
  
              '-vframes', '1', 
  
              '-f','image2', 
  
              'output.jpg'
  
          ]
  
          //console.log(args)
  
          var ffmpeg = require('child_process').spawn('ffmpeg', args);
  
  
  
          ffmpeg.on('error', function (err) {
  
              console.log(err);
  
          });
  
  
  
          ffmpeg.on('close', function (code) {
  
  
  
          });
  
  
  
          ffmpeg.stderr.on('data', function (data) {
  
              var tData = data.toString('utf8');
  
              var a = tData.split('\n');
  
              console.log("A",a); 
  
          });
  
  
  
          ffmpeg.stdout.on('data', function (data) {
  
              //
  
          });
  
  
  
  
  
      });

  }
