• Concatenate / Join MP4 files using ffmpeg and windows command line batch NOT LINUX

  17 juillet 2014, par julesverne

  I’ve written a batch script that attempts to take a generic introductory title video (MP4) that runs for 12 seconds and attaches it to the beginning of 4 other MP4 videos (same video but each has a different language audio track)

  According to ffmpeg syntax here : http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20concatenate%20%28join,%20merge%29%20media%20files the concat demuxer needs to be run from a text file that looks like this :

  # this is a comment
  
  file '/path/to/file1'
  
  file '/path/to/file2'
  
  file '/path/to/file3'

  I believe everything in my script up until the point of joining the files appears to be working correctly. But I get this error :

  [concat @ 04177d00] Line 2: unknown keyword ''C:\Users\Joe\1May\session3\readyforfinalconversion\frenchfile.mp4'
  
  filelistFrench.txt: Invalid data found when processing input
  
  [concat @ 03b70a80] Line 2: unknown keyword ''C:\Users\Joe\1May\session3\readyforfinalconversion\spanishfile.mp4'
  
  filelistSpanish.txt: Invalid data found when processing input
  
  [concat @ 0211b960] Line 2: unknown keyword ''C:\Users\Joe\1May\session3\readyforfinalconversion\basquefile.mp4'
  
  filelistBasque.txt: Invalid data found when processing input
  
  [concat @ 03a20a80] Line 2: unknown keyword ''C:\Users\Joe\1May\session3\readyforfinalconversion\Englishfile.mp4'
  
  filelistEnglish.txt: Invalid data found when processing input

  I believe the issue lies in the text file I’m creating. Please excuse my n00b ignorance, but sometimes new script makers like myself get confused about developer jargon and may take things literally.

  So when I look at that example text file they gave, am I correct in thinking THIS is what my text file should look like ?

  # this is a comment
  
  Titlefile.mp4 'C:\Users\Joe\1May\session3\readyforfinalconversion\Titlefile.mp4'
  
  Englishfile.mp4 'C:\Users\Joe\1May\session3\readyforfinalconversion\Englishfile.mp4'

  Again, am I being too literal ? are the quotations correct ? Are the slashes correct ? In the example they provide the slashes in the path are / instead of normal windows \ . I’ll provide the entire script in case it helps.

  EDIT
  Thanks to @foxidrive making me look at the simplicity of it... it occurred to me that Apparently I wasn’t being literal enough. I made these 3 changes and script works perfectly now
  1 : "file" in there example literally meant the word "file"
  2 : needed the use of single quotes not double quotes as it shows in there example.
  3 : Used "\" instead of "/" as they have in there example.

  So NOW my code to create the text files looks like this :

  rem create data file for ffmpeg based on variable data
  
  
  
  for /L %%i in (1,1,4) do (
  
      echo # this is a comment>>filelist!term[%
  
  
  
  %i]!.txt
  
      echo file '%pathtotitlevideo%'>>filelist!term[%
  
  
  
  %i]!.txt
  
      echo file '!pathtofile[%%i]!'>>filelist!term[%
  
  
  
  %i]!.txt
  
  )

  So NOW my text file looks like this :

  # this is a comment    
  
  file 'C:\Users\Joe\1May\session3\readyforfinalconversion\Titlefile.mp4'

• HTML5 Video/Audio to Nodejs via Socket.io but with a twist - FFMPEG

  9 janvier 2014, par user1840958

  I'm writing this very simple "skype clone". I tried a variety of other languages, python and layering over Node.js with Meteor, WebRTC, but Node.js+socket.io seems to be working the best and cleanest however I've hit a road block and I can't get it all to work correctly.

  I have two issues,
  1. I think I'm sending real data from the HTML5 getUserMedia, but I might not, and I don't know how to test or find out. I think that using, "video.src = window.URL.createObjectURL(stream) ;" makes the Blob stream an actual Data stream... but I don't know.

  This is my Broadcast.html
  It's a very simple getUserMedia grab the camera and microphone... Then I connect to the Socket and on click of the Broadcast button, fires off the Emit to 'Join' and sends over the 'webcamstream' data.

  <video autoplay="autoplay" height="280"></video>
  
  <button class="recordbutton">Broadcast</button>
  
  
  
  
  
  <code class="echappe-js">&lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot;&gt;<br />
  
  var socket = io.connect(&amp;#39;http://video.domain.com:3031&amp;#39;);<br />
  
  socket.on(&amp;#39;connect&amp;#39;, function() {<br />
  
    $(&amp;#39;#conversation&amp;#39;).append(&amp;#39;Connected &lt;br /&gt;&amp;#39;);<br />
  
  });<br />
  
  <br />
  
  function onVideoFail(e) {<br />
  
    console.log(&amp;#39;webcam fail!&amp;#39;, e);<br />
  
  };<br />
  
  <br />
  
  function hasGetUserMedia() {<br />
  
    return !!(navigator.getUserMedia || <br />
  
      navigator.webkitGetUserMedia || <br />
  
      navigator.mozGetUserMedia || <br />
  
      navigator.msGetUserMedia);<br />
  
  }<br />
  
  <br />
  
  if (hasGetUserMedia()) {<br />
  
    alert(&amp;#39;It is working...&amp;#39;);<br />
  
  } else {<br />
  
    alert(&amp;#39;getUserMedia() is not supported in your browser&amp;#39;);<br />
  
  }<br />
  
  <br />
  
  window.URL = window.URL || window.webkitURL;<br />
  
  navigator.getUserMedia  = navigator.getUserMedia || <br />
  
                           navigator.webkitGetUserMedia ||<br />
  
                            navigator.mozGetUserMedia || <br />
  
                             navigator.msGetUserMedia;<br />
  
  <br />
  
  var video = document.querySelector(&amp;#39;video&amp;#39;);<br />
  
  var streamRecorder;<br />
  
  var webcamstream;<br />
  
  <br />
  
  if (navigator.getUserMedia) {<br />
  
          navigator.getUserMedia({audio: true, video: true}, function(stream) {<br />
  
              video.src = window.URL.createObjectURL(stream);<br />
  
              webcamstream = stream;<br />
  
          }, onVideoFail);<br />
  
  } else {<br />
  
     alert (&amp;#39;failed&amp;#39;);<br />
  
  }<br />
  
  <br />
  
  function startBroadcasting() {<br />
  
      alert(&amp;#39;Broadcast Now Clicked&amp;#39;);<br />
  
      console.log(webcamstream);<br />
  
      socket.emit(&amp;#39;join&amp;#39;, webcamstream);<br />
  
      socket.emit(&amp;#39;echo&amp;#39;, &amp;#39;echo1 echo2 echo3 &lt;br /&gt;&amp;#39;);<br />
  
  }<br />
  
  <br />
  
  socket.on(&amp;#39;echo&amp;#39;, function(data) {<br />
  
      $(&amp;#39;#conversation&amp;#39;).append(data);<br />
  
  }); <br />
  
  &lt;/code&gt;&lt;/pre&gt;<br />
  
  <br />
  
  &lt;p&gt;&lt;/p&gt;<br />
  
  <br />
  
  &lt;p&gt;This is the app.js<br />
  
  2. What I&amp;#39;m trying to do here is consume in the &amp;#39;stream&amp;#39; from the socket, but in it&amp;#39;s place I have a test video to see if the FFMPEG is actually working. I&amp;#39;m using &lt;a href=&quot;https://github.com/schaermu/node-fluent-ffmpeg&quot; rel=&quot;nofollow&quot;&gt;https://github.com/schaermu/node-fluent-ffmpeg&lt;/a&gt;.&lt;/p&gt;<br />
  
  <br />
  
  &lt;p&gt;When I run this test with my myth.mp4 file, I do get an out.avi however it&amp;#39;s 0 bytes ??&lt;/p&gt;<br />
  
  <br />
  
  &lt;pre&gt;&lt;code&gt;var express = require(&amp;#39;express&amp;#39;);<br />
  
  var socket = require(&amp;#39;socket.io&amp;#39;);<br />
  
  var ffmpeg = require(&amp;#39;fluent-ffmpeg&amp;#39;);<br />
  
  var fs = require(&amp;#39;fs&amp;#39;);<br />
  
  <br />
  
  var app = express();<br />
  
  <br />
  
  app.configure(function(req, res){<br />
  
      app.use(express.static(__dirname + &amp;#39;/&amp;#39;));<br />
  
  });<br />
  
  <br />
  
  var server = app.listen(3031);<br />
  
  var io = socket.listen(server);<br />
  
  <br />
  
  io.sockets.on(&amp;#39;connection&amp;#39;, function(socket) {<br />
  
      socket.on(&amp;#39;join&amp;#39;, function(stream) {<br />
  
          socket.stream = stream;<br />
  
          socket.emit(&amp;#39;echo&amp;#39;, socket.stream + &amp;#39;&lt;br /&gt;&amp;#39;);<br />
  
          var proc = new ffmpeg({source:&amp;#39;/srv/www/domain.com/video/red/myth.mp4&amp;#39;})<br />
  
              .withAspect(&amp;#39;4:3&amp;#39;)<br />
  
              .withSize(&amp;#39;640x480&amp;#39;)<br />
  
              .applyAutopadding(true, &amp;#39;white&amp;#39;)<br />
  
              .saveToFile(&amp;#39;/srv/www/domain.com/video/red/out.avi&amp;#39;, function(retcode, error){<br />
  
                  socket.emit(&amp;#39;echo&amp;#39;, &amp;#39;file has been converted succesfully &lt;br /&gt;&amp;#39;);<br />
