• How to stream an webm video through ffmpeg using node.js ?

  4 juillet 2012, par Marcos Lopes

  I have built an node.js server that gets ffmpeg video and pass it to all listeners connected, but the video doesn't play. What i'm doing wrong ?

  Here is my ffmpeg command and output : http://pastebin.com/56BMrx7V

  and in my node.js app :

  var http = require('http');
  
  
  
  var server = http.createServer(function(req, res) {  
  
      if (req.url === '/listen') {  
  
          listen(req, res);  
  
      } else if (req.url === '/publish' && req.method === 'POST') {  
  
          stream(req, res);  
  
      }  
  
  });
  
  
  
  var stream = require('stream');  
  
  var writeStream = new stream.Stream();  
  
  var listeners = [];  
  
  
  
  writeStream.writable = true;  
  
  
  
  writeStream.write = function(data) {  
  
      listeners.forEach(function(listener) {  
  
          listener.write(data);  
  
      });  
  
  };  
  
  
  
  writeStream.end = function() {  
  
      listeners.forEach(function(listener) {  
  
          listener.end();  
  
      });  
  
  };  
  
  
  
  var listen = function(req, res) {  
  
      listeners.push(res);  
  
  
  
      res.writeHead(200, {  
  
          'Date': new Date().toUTCString(),  
  
          'Connection': 'close',  
  
          'Content-Type': 'video/webm',  
  
          'Transfer-Encoding': 'chunked'  
  
      });  
  
  };  
  
  
  
  var stream = function(req, res) {  
  
      req.on('data', function(data) {  
  
          writeStream.write(data);  
  
      });  
  
  
  
      req.on('end', function() {  
  
          writeStream.end();  
  
      });  
  
  }
  
  
  
  server.listen(3000);  
  
  console.log('Listening on localhost port 3000');

  Thanks.

• nginx video mp4 streaming - jwplayer seeking

  18 juin 2012, par abrahab

  As you can see nginx streaming solution works and return different content-length when flv requested with start parameter :
  http://www.hotgirlscompany.com/1.flv?start=0
  http://www.hotgirlscompany.com/1.flv?start=300000

  But the problem that jwplayer v5 can not seek this video to any position. Seems (from http sniffer) player request ?start=0 and then ignore any mouse clicks at loading line, and can not go to position I want).

  Of course, I added provider=http to flashVars.
  You can download the video and see that its converted as H.264/AAC. Then maked mp4box -inter 500 1.flv. But still can not steam it :(

  Any suggestions ?
  Maybe example how to property reconvert this video with ffmpeg to make it playable ?

• ffmpeg image to .avi slow motion

  9 mars 2014, par Preetam Ramdhave

  I have 15 images which I want to convert in the .avi format. I am able to convert the AVI files. But when I convert it the video file not even last for 1 second. I wan to make this move slow motion.

  ffmpeg -f image2 -i C:\\SecurePass\\APU\\ProcessedFiles\\2e54026b-e2e8-4796-917a-
26313eeaee5a__T0000100001_%d.jpg -r 30 -s  300x400 C:\\SecurePass\\APU\\VideoFiles\\T0000100001_3.avi

  I am using above command. the above command is converting the image file.

  What should I do in this case ?

  I want to build this slow motion move and it should be in .avi format.
