createroom error

[david_c_1]

Hi,

I get the following error when I call N.API.createRoom (I use Node 6.9.5)

/opt/intelcs/webrtc/Release-v3.4/extras/basic_example/nuve.js:8 

TypeError: a.forEach is not a function
   at c (/opt/intelcs/webrtc/Release-v3.4/extras/basic_example/nuve.js:8:10901)
   at Object.e [as createRoom] (/opt/intelcs/webrtc/Release-v3.4/extras/basic_example/nuve.js:8:11273)

....

the api I call is:

N.API.createRoom(roomName, 

{

 mode: 'hybrid',

 publishLimit: -1,

 userLimit: 200,

 viewports: {

   "common": {

 mediaMixing: {

   video: {

     maxInput: 30,

     resolution: 'hd720p',

     multistreaming: 1,

     bitrate: 300,

     bkColor: {"r":0, "g":0, "b":0},

     layout: {

     custom: '[{"region":[{"id": "1", "left": 0,"top": 0,"relativesize": 1}]},{"region": [{"id": "1","left": 0,"top": 0.25,"relativesize": 0.49 }, {"id": "2", "left": 0.51, "top": 0.25,"relativesize": 0.49 }]}]'

     },

     avCoordinated: 0,

     crop: 1

   },

   audio: null

 },

 sipInfo:{

    sipServer:'127.0.0.1',

    username:'phone',

    password:'xxx'

 }

   }

}

}, 

function (roomID) {

myRoom = roomID._id;

console.log('Created room ', myRoom);

var type = 'socketio';

var preference = {isp: 'isp', region: 'region'};

N.API.createToken(myRoom, username, role, type, preference,  function (token) {

console.log(token);

res.send( JSON.stringify({token: token , roomId: myRoom}) );

return;

}, function() {

// errore createToken

res.send(getExceptionJ("Errore durante la creazione del Token di accesso.", err));

return;

});  // end gestione createToken

}, 

function() {

// errore createRoom

res.send(getExceptionJ("Errore durante la creazione della Room.", err));

return;

}

);

Hi, there are 2 issues in the createRoom data:

1. as document https://software.intel.com/sites/products/documentation/webrtc/js/class_n_1_1_a_p_i.html#a54e2842c746d3a992891635a571cf511 defined: viewport values should be an array not an object

2. common  should be the value, its key should be name, viewports should work if defined like this: 

viewports:[{name:"common", mediaMixing: {}}]

[david_c_1]

Thanks for the reply. 

I think you have to correct the example in the documentation on the page you mentioned. My code was taken up exactly from this example:

N.API.createRoom('myRoom', {

mode: 'hybrid',

publishLimit: -1,

userLimit: 30,

viewports: {

"common": {

mediaMixing: {

video: {

maxInput: 15,

resolution: 'hd720p',

multistreaming: 1,

bitrate: 0,

bkColor: {"r":1, "g":2, "b":255},

layout: {

base: 'lecture',

},

avCoordinated: 1,

crop: 1

},

audio: null

},

},

"another": {

mediaMixing: {

video: {

maxInput: 15,

resolution: 'hd1080p',

multistreaming: 1,

bitrate: 0,

bkColor: {"r":1, "g":2, "b":255},

layout: {

base: 'lecture',

},

avCoordinated: 1,

crop: 1

},

audio: null

},

}

}

}, function (res) {

console.log ('Room', res.name, 'created with id:', res._id);

}, function (err) {

console.log ('Error:', err);

});

Thanks for the correction, we will update doc in the future release

Hi,

I'm trying to create a room with the options below. However the room is created with the default options and no viewport is created.

In the logs I do not seem to see any  error.

What am I doing wrong?

opts = { 

        mode: 'hybrid',

        publishLimit: -1,

        userLimit: 200,

        enableMixing : 1,

        viewports: [

        {

                   name : "common",

                   mediaMixing: {

                  video: {

                            maxInput: 30,

                            resolution: 'hd1080p',

                            multistreaming: 1,

                            bitrate: 300,

                            bkColor: {"r":0, "g":0, "b":0},

                            layout: {

                                    custom: [{"region":[{"id": "1", "left": 0,"top": 0,"relativesize": 1}]},{"region": [{"id": "1","left": 0,"top": 0.25,"relativesize": 0.49                                                     }, {"id": "2", "left": 0.51, "top": 0.25,"relativesize": 0.49 }]}]

Hi,

no indication on my last question?

[Qiujiao_W_Intel]

Hi, David, there is a bug in v3.4 for viewport, and we have fixed it in v3.4.1. Please use MCU with 3.4.1

[david_c_1]

updating to version 3.4.1 has resolved the problem, but the mixed stream bitrate does not meet the maximum set limit of 300 Kbs. It is around 2 Mbps. Why?

[Qiujiao_W_Intel]

Hi, david, bitrate option in createRoom API is deprecated in 3.4, if you want to limit bitrate of subscribed stream, please specify qualituLevel option in subscribe API.

[Qiujiao_W_Intel]

one mistake in previous comment, should be qualityLevel:

Hi, david, bitrate option in createRoom API is deprecated in 3.4, if you want to limit bitrate of subscribed stream, please specify qualityLevel option in subscribe API.

[david_c_1]

Ok thanks for the reply but I would like to understand in more detail the effect of these parameters on a video session of "n" participants with heterogeneous network bandwidth. 

I'm developing a web conference application that aims to have 100 participants, so I have to be sure of the network bandwidth that I have to allocate on the server.

many thanks for the kind reply you will give me

David

[Qiujiao_W_Intel]

For subscribe actions, bandwidth mainly related to resolution and qualityLevel, here is a reference table for bitrate in different resolution and qualityLevel:
