• Why does ffmpeg.exe started from Windows batch file close immediately without waiting for user input ?

  12 juin 2017, par user2566350

  I searched google for an hour but I could not find anything to fix my issue. I found only "similar" fixes for problems I’m not having.

  I am opening ffmpeg.exe from a batch file that only has ffmpeg.exe with no arguments in it and it doesn’t work even though it did few hours ago.

  If I open command line from the folder and enter ffmpeg.exe it works because it’s not closing ffmpeg but waits for my input which is exactly how the batch file worked before.

  What could be the issue ?

  I have not changed the batch file or ffmpeg one or their locations.

  Running on Windows 7 x64 if that matters.

  Edit : File name is start ffmpeg.bat. It’s content is only ffmpeg.exe which used to work. I also tried start ffmpeg.exe and ffmpeg and changed the filename to 1.bat and 1.cmd but neither worked.

  Edit2 : Sorry i can’t explain myself better my english isn’t very good, however I will try to explain using these images :

  
  This is what i get if i run CMD from the desktop and enter ffmpeg.exe

  
  This is what I get when i run the batch file (after i added pause)
  Batch contents : 1st line=ffmpeg.exe, 2nd line=pause.

  As you can see without the pause ffmpeg will terminate and not remain on the screen like the in first image.

  I tried renaming the file and I tried to run it as admin but neither worked, Any suggestion why is it suddenly not running as it did yesterday ?

• 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

• Combining Video and Audio of different length in bulk

  25 mai 2017, par user2981223

  I am going through a tv series right now and editing the files to be to my liking. I have one set which has the video I want and one set that has the audio. I have a batch file that I can run that takes the video from every file in folder "A" and the audio from every file in folder "B" and outputs it to a folder named "output." But with this particular series, that is only half of what I need done.

  At the end of every episode of the files in the "B" folder there are some extra things. What I would like to do is take the audio and video from "A" and the audio from "B", combine it all into one file and also take the "A" and "B" files, compare the time stamps, and add the extra video from "B" to the output file.

  Let me put it another way. Let’s say "A" is 1080p with Japanese audio and is 20 minutes long. Let’s say "B" is 720p with English audio and is 23 minutes long. I want the whole 1080p video with both audio tracks, plus the 720p video spliced onto the end. Both files start at the same spot so syncing isn’t an issue. The issue is that the difference in time is different for every episode. So some episodes are 3 minutes longer, some only 30 seconds. Is there a way to make ffmpeg or another tool look at the difference in times and just add the excess to the output file ?

  Sorry for being long winded. Thanks for any help and guidance.
