• avformat/segment : Use ff_stream_encode_params_copy()

  avformat/segment : Use ff_stream_encode_params_copy()
  It is simpler and more complete (e.g. it copies the id).

• FFMPEG is not working in AWS lambda function

  13 novembre 2022, par Arun

  I am trying to convert a video file into an audio file using AWS lambda function whenever a file is uploaded into an S3 bucket. So I am using FFMPEG for converting a video file into audio. But I keep getting this error while converting a video file. I have seen similar questions but none of the solutions is not working for me. So If anyone knows please share your solutions.

  



  Error message

  



      TypeError: Cannot create property 'stack' on string 
'Could not find ffmpeg executable, tried "/var/task/node_modules/@ffmpeg-installer/linux-x64/ffmpeg" and "/var/task/node_modules/@ffmpeg-installer/ffmpeg/node_modules/@ffmpeg-installer/linux-x64/ffmpeg"'


  



  Code

  



      const
    ffmpegPath = require("@ffmpeg-installer/ffmpeg").path,
    ffmpeg = require("fluent-ffmpeg");

    // set ffmpeg package path
    ffmpeg.setFfmpegPath(ffmpegPath);
    function convert(input, output, callback) {
        ffmpeg(input)
            .output(output)
            .on('end', function() {                    
                console.log('conversion ended');
                callback(null);
            }).on('error', function(err){
                console.log('error: ', err.code, err.msg);
                callback(err);
            }).run();
    }

    exports.handler = function (event, context, callback) {
        const key = decodeURIComponent(event.Records[0].s3.object.key.replace(/\+/g, ' '));
        console.log("key ", key);
        console.log("event ", event.Records[0].s3);
        convert(key, `/tmp/${key}.mp3`, function(err){
            if(!err) {
                console.log('conversion complete');
            } else {
                console.log('Error');
            }
        });
    }


    const
        ffmpegPath = require("@ffmpeg-installer/ffmpeg").path,
        ffmpeg = require("fluent-ffmpeg");

    // set ffmpeg package path

• promise fluent-ffmpeg Nodejs

  6 décembre 2018, par babak abadkheir

  I’m trying convert video to .flv with ffmpeg. converting is a long time process . and it depends on file size duration and other parameters.

  const vodConvert = async (dir, id, ext) => new Promise((resolve) => {
  
      const ffmpegPath = '/usr/bin/ffmpeg';
  
      ffmpeg.setFfmpegPath(ffmpegPath);
  
      ffmpeg(`${dir}temp.${ext}`).saveToFile(`${dir}${id}.flv`);
  
      resolve();
  
  
  
  });

  after ffmpeg done I need to remove the original file.

  const del = require('del');
  
  del(`${dir}temp.*`)

  so how to tell my promise function if proccess complete then delete the original file.
  I even tried this :

  vodConvert(dir, id, ext).then(del(`${dir}temp.*`)
