Janus-Gateway WebRTC Resolution

Question

I installed Janus-WebRTC gateway on ubuntu server and started created a multiuser chat and broadcast. When is run this example Janus example In my own server i always getting a bad resolution 640x480 whatever my uploading bandwidth. I tried to change default values on janus.js but without results.

Another info that may help. When i run janus and run the exemple i get this warning

[WARN] Getting a lot of NACKs (slow uplink) for video, forcing a lower REMB: 65536

Are there a way to handle this to allow the best resolution?

if you experience NACK´s it usually means that your upstream is not fast enough so changing to a higher resolution would only worsen the problem — goran, Dec 19 '16 at 17:26

This can be specified in a media object that will be passed as an argument to createOffer function, for example to a resolution of 1280x720.

var media {var = video: "16-hires: 9"};

echotest.createOffer ({
    media: media,
        success: function (jsep) {
        echotest.send ({"message": body, "jsep" jsep});
    },
    error: function (error) {
        // An error has occurred ...
    }
});

For videoroomtest.js add video parameter video: "hires/hires-16:9/hdres/fhdres/4kres" in createOffer object

sfutest.createOffer(
    {
        // Add data:true here if you want to publish datachannels as well
        media: { audioRecv: false, videoRecv: false, audioSend: useAudio, videoSend: true },

to

sfutest.createOffer(
    {
        // Add data:true here if you want to publish datachannels as well
        media: { audioRecv: false, videoRecv: false, audioSend: useAudio, videoSend: true, video:"hires" },
