Nodejs, Android - Video Streaming

I am working on an application which displays videos from Nodejs& MongoDB server. The problem here is because the videos are not streaming, mediaPlayer on Android fully downlo

Solution 1:

While dedicated streaming servers are probably a better solution for any sizeable solution, or any solution requiring good performance, you definitely should be able to stream video files from a standard node.js application.

The simplest way is to place the videos in a directory somewhere on the server and serve them as static content.

The following very basic node,js app will serve video - you access it from your base url followed by the directory and video file name - e.g. http://[your server url]/videos/[name of your video file]

var express = require('express');
var fs = require('fs');
var morgan = require('morgan');

//Define the appvar app = express();

// create a write stream (in append mode)var accessLogStream = fs.createWriteStream(__dirname + '/access.log', {flags: 'a'});

// setup the logger
app.use(morgan('combined', {stream: accessLogStream}));

// ConstantsvarPORT = 3000;

//Use static middleware to serve static content - using absolute paths here (you may want something different)
app.use('/videos', express.static('/videos'));

//Add error handling
app.use(function(err, req, res, next) {
    console.log("error!!!");
    console.log(err.stack);
});

// Video Server test page
app.get('/', function (req, res) {
    console.log("In Get!!!");
    res.send('Hello world from Video server\n');
});

//Start web servervar server = app.listen(PORT, function () {
    var host = server.address().address;
    var port = server.address().port;

    console.log('Example app listening at http://%s:%s', host, port);
});

One reason why simple HTTP streaming might not be working for you is if your server does not support range request. This mechanism allows the client request just a portion of the file at a time. See here for more info:

Solution 2:

You have not given details about your application. RTSP or HLS are streaming formats having some advantages over other as per requirement, and Android supports both and more as well.
