• Splitting more then once with a library

  12 mai 2017, par Fearhunter

  I am doing a research for split video’s in four files for example. I was looking at this repository on github.

  https://github.com/vdaubry/html5-video-splitter

  It’s a very nice repo how to split a video. My question is : how can I split more files then only one cut ? When I split for the second time it will overwrite the previous one. Here is the open source code of the splitting :

  var childProcess = require("child_process");
  
  childProcess.spawn = require('cross-spawn');
  
  
  
  var http = require('http');
  
  var path = require("path"); 
  
  var fs = require("fs"); 
  
  var exec = require('child_process').exec;
  
  
  
  http.createServer(function (req, res) {
  
    if (req.method === 'OPTIONS') {
  
        console.log('!OPTIONS');
  
        var headers = {};
  
        headers["Access-Control-Allow-Origin"] = "*";
  
        headers["Access-Control-Allow-Methods"] = "POST, GET, PUT, DELETE, OPTIONS";
  
        headers["Access-Control-Allow-Credentials"] = false;
  
        headers["Access-Control-Max-Age"] = '86400';
  
        headers["Access-Control-Allow-Headers"] = "X-reqed-With, X-HTTP-Method-Override, Content-Type, Accept";
  
        res.writeHead(200, headers);
  
        res.end();
  
    } 
  
    else if (req.method == 'POST') {
  
      var body = '';
  
      req.on('data', function (data) {
  
          body += data;
  
      });
  
      req.on('end', function () {
  
          var data = JSON.parse(body);
  
          var localPath = __dirname;
  
          var inputFilePath = localPath+"/videos/"+data.inputFilePath;
  
          var outputFilePath = localPath+"/videos/output-"+data.inputFilePath
  
          var start = data.begin;
  
          var end = data.end;
  
  
  
          var command = "ffmpeg -y -ss "+start+" -t "+(end-start)+" -i "+inputFilePath+" -vcodec copy -acodec copy "+outputFilePath;
  
          exec(command, function(error, stdout, stderr) {
  
            var msg = ""
  
            if(error) {
  
              console.log(error);
  
              msg = error.toString();
  
              res.writeHead(500, {'Content-Type': 'text/plain'});
  
            }
  
            else {
  
              console.log(stdout);
  
              res.writeHead(200, {'Content-Type': 'text/plain'});
  
            }
  
            res.end(msg);
  
          });
  
      });
  
    }
  
    else if (req.method == 'GET') {
  
      var filename = "index.html";
  
      if(req.url != "/") {
  
        filename = req.url
  
      }
  
  
  
      var ext = path.extname(filename);
  
      var localPath = __dirname;
  
      var validExtensions = {
  
        ".html" : "text/html",      
  
        ".js": "application/javascript", 
  
        ".css": "text/css",
  
        ".txt": "text/plain",
  
        ".jpg": "image/jpeg",
  
        ".gif": "image/gif",
  
        ".png": "image/png",
  
        ".ico": "image/x-icon"
  
      };
  
      var mimeType = validExtensions[ext];
  
  
  
      if (mimeType) {
  
        localPath += "/interface/"+filename;
  
        fs.exists(localPath, function(exists) {
  
          if(exists) {
  
            console.log("Serving file: " + localPath);
  
            getFile(localPath, res, mimeType);
  
          } else {
  
            console.log("File not found: " + localPath);
  
            res.writeHead(404);
  
            res.end();
  
          }
  
        });
  
  
  
      } else {
  
        console.log("Invalid file extension detected: " + ext)
  
      }
  
    }
  
  }).listen(1337, '127.0.0.1');
  
  console.log('Server running at http://127.0.0.1:1337/');
  
  
  
  function getFile(localPath, res, mimeType) {
  
    fs.readFile(localPath, function(err, contents) {
  
      if(!err) {
  
        res.setHeader("Content-Length", contents.length);
  
        res.setHeader("Content-Type", mimeType);
  
        res.statusCode = 200;
  
        res.end(contents);
  
      } else {
  
        res.writeHead(500);
  
        res.end();
  
      }
  
    });
  
  }

  I have installed FFMPEG also to do this.

  Kind regards

  fftools/ffmpeg_filter : also remove display matrix side data from buffered frames
  Some frames may be buffered before a complex filtergraph can be configured.
  
  This change ensures the side data removal in the cases where autorotation is
  
  enabled also applies to them.
  Fixes ticket #11487

  I think is because ffmpeg is not connecting to mongodb
