How to get specific start & end time in ffmpeg by Node JS?

Question

I want to cut a video in specific start & end time & save it. I cant understand how to cut specific time of that video by Node JS.

Video copy code :

 return new Promise(function(resolve ,reject){
        var ffmpeg = require('fluent-ffmpeg');
        ffmpeg(fs.createReadStream(path.join(__dirname,'..','..','/video.mp4')))
            .seekInput('01:00')
            .duration('02:00')
            .outputOptions('-strict experimental')
            .on('start', function(commandLine) {
                console.log('Spawned Ffmpeg with command: ' + commandLine);
                }).on('end', function(err) {
                if (!err) {
                    console.log('conversion Done');
                    //res.send("conversion Done");
                    resolve();
                }
                }).on('error', function(err) {
                    console.log('error: ', +err);
                    reject(err);
                }).save(path.join(__dirname,'..','..','/test.mp4'));
    });

Please check following steps and sample code,

Install ffmpeg installed on your system steps
Install module fluent-ffmpeg in your project

Please check following sample code

  function clipVideo() {

      var params = {
        input: 'input_file',
        start: 0,
        duration: 10,
        output: 'output_file'
      };

      return new Promise(function(resolve, reject) {

          ffmpeg(params.input)
              .setStartTime(params.start)
              .setDuration(params.duration)
              .save(params.output)
              .on('start', function(commandLine) {
                  console.log('start : ' + commandLine);
              })
              .on('progress', function(progress) {
                  console.log('In Progress !!' + Date());
              })
              .on('end', function() {
                  console.log("downlaod resolved");
                  return resolve(params.clippedFile);

              })
              .on('error', function(err) {
                  console.log("reject");
                  return reject(err);
              })
      });
  }

Hope this will help you !!

I am getting an error after executing above code ```an error happened: ffmpeg exited with code 1: home/santosh/video1.avi: Invalid data found when processing input``` — Santosh Suryawanshi, Nov 03 '17 at 10:39
you needs to passed full path of input video and output path , for example Users/santosh/Documents/Workspace/VideoClip/routes/input.mp4 — Santosh Shinde, Nov 03 '17 at 10:46
