JSmpeg is not playing audio from websocket stream
5 juin 2023, par NikI am trying to stream RTSP to web browser using ffmpeg through web socket relay written in node js taken from https://github.com/phoboslab/jsmpeg , and on the browser i am using JSMpeg to display the RTSP stream, the video is playing fine, but audio is not playing,


The ffmpeg command :


ffmpeg -rtsp_transport tcp -i rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4 
 -f mpegts -c:v mpeg1video -c:a mp2 http://127.0.0.1:8081/stream_from_ffmpeg/


The node js web socket relay :


// Use the websocket-relay to serve a raw MPEG-TS over WebSockets. You can use
// ffmpeg to feed the relay. ffmpeg -> websocket-relay -> browser
// Example:
// node websocket-relay yoursecret 8081 8082
// ffmpeg -i <some input="input"> -f mpegts http://localhost:8081/yoursecret

var fs = require('fs'),
 http = require('http'),

 process.exit();
}

var STREAM_SECRET = process.argv[2],
 STREAM_PORT = process.argv[3] || 8081,
 WEBSOCKET_PORT = process.argv[4] || 8082,
 RECORD_STREAM = false;

// Websocket Server
var socketServer = new WebSocket.Server({port: WEBSOCKET_PORT, perMessageDeflate: false});
socketServer.connectionCount = 0;
socketServer.on('connection', function(socket, upgradeReq) {
 socketServer.connectionCount++;
 console.log(
 'New WebSocket Connection: ',
 (upgradeReq || socket.upgradeReq).socket.remoteAddress,
 (upgradeReq || socket.upgradeReq).headers['user-agent'],
 '('+socketServer.connectionCount+' total)'
 );
 socket.on('close', function(code, message){
 socketServer.connectionCount--;
 console.log(
 'Disconnected WebSocket ('+socketServer.connectionCount+' total)'
 );
 });
});
socketServer.broadcast = function(data) {
 socketServer.clients.forEach(function each(client) {
 if (client.readyState === WebSocket.OPEN) {
 client.send(data);
 }
 });
};

// HTTP Server to accept incoming MPEG-TS Stream from ffmpeg
var streamServer = http.createServer( function(request, response) {
 var params = request.url.substr(1).split('/');

 if (params[0] !== STREAM_SECRET) {

The front end code




 
 
 
 
 <code class="echappe-js"><script src='http://stackoverflow.com/feeds/tag/jsmpeg.min.js'></script>
 
 
 
 
 
<script>&#xA; let url;&#xA; let player;&#xA; let canvas = document.getElementById("video-canvas");&#xA; let ipAddr = "127.0.0.1:8082";&#xA; window.onload = async() => {&#xA; url = `ws://${ipAddr}`;&#xA; player = new JSMpeg.Player(url, { canvas: canvas, });&#xA; };&#xA;&#xA; </script>




The above code works fine and plays the video, but no audio is playing
Things I tried :


Changed the audio context state inside the player object from suspended to running


player.audioOut.context.onstatechange = async () => {
 console.log("Event triggered by audio");

 if (player.audioOut.context === "suspended") {
 await player.audioOut.context.resume();
 }
}

MPEG-DASH - Multiplexed Representations Issue
26 avril 2017, par MikeI’m trying to learn ffmpeg, MP4Box, and MPEG-DASH, but I’m running into an issue with the .mp4 I’m using. I’m using ffmpeg to demux the mp4 with this command :
ffmpeg -i test.mp4 -c:v copy -g 72 -an video.mp4 -c:a copy audio.mp4Once the two files are created, I use MP4Box to segment the files for the dash player using this command :
MP4Box -dash 4000 -frag 1000 -rap -segment-name segment_ output.mp4Which does create all the files I think I need. Then I point the player to the output_dash.mpd and nothing happens except a ton of messages in the console :

Alternate Group ID 1I know I need to separate the video and audio and I think that’s where my issue is. The command I’m using probably isn’t doing the right thing.
Is there a better command to demux my mp4 ?
Is the MP4Box command I’m using best for segmenting the files ?
If I use different files, will they always need to be demuxed ?One thing to mention, if I use the following commands everything works fine, but there is no audio because of the
-anwhich means it’s only video :ffmpeg -i test.mp4 -c:v copy -g 72 -an output.mp4
MP4Box -dash 4000 -frag 1000 -rap -segment-name segment_ output.mp4UPDATE
I noticed that the video had no audio stream, but the audio had the video stream which is why I got the mux error. I thought that might be an issue so I ran this command to keep the unwanted streams out of the outputs :
ffmpeg -i test.mp4 -c:v copy -g 72 -an video.mp4 -c:a copy -vn audio.mp4then I run :
MP4Box -dash 4000 -frag 1000 -rap -segment-name segment_ video.mp4 audio.mp4now I no longer get the Multiplexed representations are intentionally not supported... message, but now I get :
[122] Video Element Error: MEDIA_ERR_SRC_NOT_SUPPORTED
[123] [object MediaError]
[125] Schedule controller stopping for audio
[126] Caught pending play exception - continuing (NotSupportedError: Failed to load because no supported source was found.)I tried playing the video and audio independently through Chrome and they both work, just not through the dash player. Ugh, this is painful to learn, but I feel like I’m making progress.
