I am waiting for requests, you can parse it as for loop that create those
objects -
new Mpeg1Muxer({
url: this.streamUrl,
timer: this.timer,
name: this.name,
sid : this.stream_id
});
And the implementation of this object is :
(function() {
var Mpeg1Muxer, child_process, events, util;
child_process = require('child_process');
util = require('util');
events = require('events');
Mpeg1Muxer = function(options) {
var self;
self = this;
this.url = options.url;
this.timer = options.timer;
this.name = options.name;
this.sid = options.sid;
var fs = require('fs');
var dir = 'LOCATION_DIR';
if (!fs.existsSync(dir)){
fs.mkdirSync(dir);
}
this.stream = child_process.spawn("ffmpeg",['-i',this.url,'-t',this.
timer/1000,'-preset','ultrafast','-threads','2','-r',(1/3),'-an','-y',
'-update','1','SOME_DIR/1.jpg'] , {
detached: false
});
this.inputStreamStarted = true;
this.stream.stdout.on('data', function(data) {
return self.emit('mpeg1data', data);
});
this.stream.stderr.on('data', function(data) {
return self.emit('ffmpegError', data);
});
return this;
};
util.inherits(Mpeg1Muxer, events.EventEmitter);
module.exports = Mpeg1Muxer;
}).call(this);
this is not the problem of the implementation in the code, its problem of
the limitation of "FFMPEG" processes that I can create.
If you have other solutions, I would like to hear!
thanks anyway.
