HTML5 Video/Audio to Nodejs via Socket.io but with a twist - FFMPEG
9 janvier 2014, par user1840958I'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"><script language="javascript" type="text/javascript"><br />
var socket = io.connect(&#39;http://video.domain.com:3031&#39;);<br />
socket.on(&#39;connect&#39;, function() {<br />
$(&#39;#conversation&#39;).append(&#39;Connected <br />&#39;);<br />
});<br />
<br />
function onVideoFail(e) {<br />
console.log(&#39;webcam fail!&#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(&#39;It is working...&#39;);<br />
} else {<br />
alert(&#39;getUserMedia() is not supported in your browser&#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(&#39;video&#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 (&#39;failed&#39;);<br />
}<br />
<br />
function startBroadcasting() {<br />
alert(&#39;Broadcast Now Clicked&#39;);<br />
console.log(webcamstream);<br />
socket.emit(&#39;join&#39;, webcamstream);<br />
socket.emit(&#39;echo&#39;, &#39;echo1 echo2 echo3 <br />&#39;);<br />
}<br />
<br />
socket.on(&#39;echo&#39;, function(data) {<br />
$(&#39;#conversation&#39;).append(data);<br />
}); <br />
</code></pre><br />
<br />
<p></p><br />
<br />
<p>This is the app.js<br />
2. What I&#39;m trying to do here is consume in the &#39;stream&#39; from the socket, but in it&#39;s place I have a test video to see if the FFMPEG is actually working. I&#39;m using <a href="https://github.com/schaermu/node-fluent-ffmpeg" rel="nofollow">https://github.com/schaermu/node-fluent-ffmpeg</a>.</p><br />
<br />
<p>When I run this test with my myth.mp4 file, I do get an out.avi however it&#39;s 0 bytes ??</p><br />
<br />
<pre><code>var express = require(&#39;express&#39;);<br />
var socket = require(&#39;socket.io&#39;);<br />
var ffmpeg = require(&#39;fluent-ffmpeg&#39;);<br />
var fs = require(&#39;fs&#39;);<br />
<br />
var app = express();<br />
<br />
app.configure(function(req, res){<br />
app.use(express.static(__dirname + &#39;/&#39;));<br />
});<br />
<br />
var server = app.listen(3031);<br />
var io = socket.listen(server);<br />
<br />
io.sockets.on(&#39;connection&#39;, function(socket) {<br />
socket.on(&#39;join&#39;, function(stream) {<br />
socket.stream = stream;<br />
socket.emit(&#39;echo&#39;, socket.stream + &#39;<br />&#39;);<br />

ffmpeg errors when playing a playlist - Non monotonous DTS
20 novembre 2023, par Evilmachinei have a strange bug in ffmpeg. I am using ffmpeg to stream Twitch VODs and CLIPs to a 24/7 twitch channel. If i stream the files one by one its working. If i am streaming a playlist containing vods and clips i get this error when the shorter clips are playing :


[flv @ 0x555677050c60] Non-monotonous DTS in output stream 0:0; previous: 56867, current: 31846; changing to 56867. This may result in incorrect timestamps in the output file.

and the video stops. Once the playlist has a longer vod again it is working.


here is my code that i use to stream :


while [ 1 -eq 1 ]
do
ffmpeg -fflags +igndts -re -f concat -safe 0 -i playlist.txt -codec copy -flvflags no_duration_filesize -f flv rtmp://XXXXXXXXX
done


If i look into ffprobe the files seems both to be normal :


VODs
