Jitsi 1.2 - No video

Hello guys.

I've just installed Jitsi 1.3.

What Do I have to do to make the video works fine?

I follow this guide https://community.igniterealtime.org/docs/DOC-2693. I tried with version 1.2 and 1.3 but, both doesn't show the video.

config.js:

var config = {

    hosts: {

        domain: 'chat.domain',

        muc: 'conference.chat.domain' // FIXME: use XEP-0030

        bridge: 'jitsi-videobridge.chat.domain' // FIXME: use XEP-0030

    },

    useIPv6: false, // ipv6 support. use at your own risk

    useNicks: false,

    useWebsockets: true,

    resolution: "360",

    bosh: window.location.protocol + "//" + window.location.host + '/http-bind/$

};

Someone can help me?
