debugWebRTC

A tiny JavaScript debugging utility using WebRTC getStats API to debug WebRTC Application.

Installation & Usage

npm

$ npm install debugwebrtc
var DebugWebRTC = require('debugwebrtc');
var peer = new RTCPeerConnection({
    iceServers: DebugWebRTC.freeice(),
    iceTransportPolicy: 'all',
    rtcpMuxPolicy: 'require',
    bundlePolicy: 'max-bundle'
});
 
var debug = new DebugWebRTC({
       peer: peer,
       interval: 1000
});
 
//TYPES
debug.on(DebugWebRTC.TYPES.TYPE_VIDEOBWE, function (results) {
    // do your work
});
 
//PARSERS
debug.on(DebugWebRTC.PARSERS.PARSER_CHECK_AUDIO_TRACKS, function (audio) {
    //do your work
});
 
debug.stop();//Stop getting statistics, you can re-start it by start api
debug.start();//Re-start getting statistics 
 
 
//......
//......
//......
 
//Stop getting the statistics and destroy the instance
debug.desroy();

You just need to have Node.js to build debugwebrtc.js and debugwebrtc.min.js

  1. Install Node.js
  2. Install gulp-cli (>= 1.2.2) globally (which provides the gulp command):
$ npm install -g gulp-cli
  1. Install the Node.js dependencies:
$ npm install
  1. Finally, run gulp dist (or just gulp) to get:
  • dist/debugwebrtc.js: uncompressed version of DebugWebRTC.
  • dist/debugwebrtc.min.js: compressed version of DebugWebRTC.
$ gulp dist
  1. then you can use it directed in your web page as follows:
<!DOCTYPE html>
<html>
<head>
    <title></title>
    <script src="./dist/debugwebrtc.js"></script> 
</head>
<body>
    <script>
        var peer = new RTCPeerConnection({
            iceServers: DebugWebRTC.freeice(),
            iceTransportPolicy: 'all',
            rtcpMuxPolicy: 'require',
            bundlePolicy: 'max-bundle'
        });
        var debug = new DebugWebRTC({
            peer: peer,
            interval:1000
        });
 
        //TYPES
        debug.on(DebugWebRTC.TYPES.TYPE_VIDEOBWE, function (results) {
            // do your work
        });
 
        //PARSERS
        debug.on(DebugWebRTC.PARSERS.PARSER_CHECK_AUDIO_TRACKS, function (audio) {
            //do your work
        });
 
    </script> 
 
</body>
</html>

TYPES

var DebugWebRTC = require('debugwebrtc');
var debug = new DebugWebRTC(option);
 
//debug.on(DebugWebRTC.TYPES.TYPE_xxxxxxx);
//DebugWebRTC.TYPES
 

The utility defines several types, and when you listen to a type, you can get that type of data. All available types are as follows:

TYPES Representation
TYPE_GOOG_TRACK 'googTrack':googTrack infomations
TYPE_GOOG_LIBJINGLE_SESSION 'googLibjingleSession':googLibjingleSession infomations
TYPE_GOOG_CERTIFICATE 'googCertificate':googCertificate infomations
TYPE_GOOG_COMPONENT 'googComponent':googComponent infomations
TYPE_GOOG_CANDIDATE_PAIR 'googCandidatePair':googCandidatePair infomations
TYPE_LOCAL_CANDIDATE 'localcandidate':localcandidate infomations
TYPE_REMOTE_CANDIDATE 'remotecandidate':remotecandidate infomations
TYPE_SSRC 'ssrc': ssrc infomations
TYPE_VIDEOBWE 'VideoBwe': VideoBwe infomations
TYPE_ALL 'all':all infomations

PARSERS

var DebugWebRTC = require('debugwebrtc');
var debug = new DebugWebRTC(option);
 
//debug.on(DebugWebRTC.PARSERS.PARSE_xxxxxxx);
//DebugWebRTC.PARSERS
 

In addition to the type, the utility also defines several parsers because the type used is to get the raw data for that type, and in most cases we often want to get the analyzed data.Then these parsers will be introduced one by one。

PARSERS Representation
PARSER_CHECK_IF_OFFERER 'checkIfOfferer': check is offerer or not
PARSER_GET_PRINT_ALGORITHM 'getPrintAlgorithm': get print algorithm, 'sha-256' e.g.
PARSER_CHECK_AUDIO_TRACKS 'checkAudioTracks': get audio tracks
PARSER_CHECK_VIDEO_TRACKS 'checkVideoTracks': get video tracks
PARSER_GET_LOCAL_CANDIDATES 'getLocalCandidates': localcandidates
PARSER_GET_REMOTE_CANDIDATES 'getRemotecandidate':remotecandidates

PARSER_GET_DATA_SENT_RECEIVED 'getDataSentReceived': data sent or reveied
PARSER_GET_STREAMS 'getStreams': streams

Custom parsers

You can add custom parsers by extending the DebugWebRTC.statsParser object. For example, if you wanted to add support for get xxx data, you could do something like:

var DebugWebRTC = require('debugwebrtc');
 
//The type of the results is an array,it is the original data of the current PeerConnection instance, that is, the data obtained when TYPE = 'all'.
DebugWebRTC.statsParser.xxx = function(results){
    //do your logic
    //and then return your result
};
 
var debug = new DebugWebRTC({
       peer: peer,
       interval: 1000
});
 
//Custom PARSERS
debug.on('xxx', function (result) {
    // do your work
});
