  • 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 />

<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 server = app.listen(3031);<br />
    
var io = socket.listen(server);<br />

  • Cannot open ".mp4" video files using OpenCV 2.4.3, Python 2.7 in Windows 7 machine

    28 décembre 2015, par tjmonsi

    I am currently working on a project that involves reading mp4 video files.
    The problem I encountered is that it using Python 2.7 (32 bit), OpenCV 2.4.3 (cv2.pyd) in a Windows 7 machine.

    The code snippet is as follows :

    try:
    
        video = cv2.VideoCapture("video.mp4")
    
except:
    
        print "Could not open video file"
    
        raise
    
print video.grab()

    "video.grab()" always returns false : meaning it doesn’t read the file "video.mp4"
    But when we try this :

    try:
    
        video = cv2.VideoCapture("video.avi")
    
except:
    
        print "Could not open video file"
    
        raise
    
print video.grab()

    "video.grab()" returns true : meaning it is able to read ".avi" files.

    Another is we have tried this same snippet on Linux and Mac and it seems to work fine, meaning it is able to read both mp4 files and avi files.

    This problem is similar to this problem and this problem. Both still don’t have a clear and workable answer.

    I would appreciate any help or workaround aside from just using Linux or Mac for programming this as I need this to work on all three systems.
