webrtcbin: browser generated offer, never connects
When having the browser generate an offer to webrtcbin, it never connects. Not sure if has to do with the ice candidates gathered from webrtbin or chrome, but i am noticing a difference. I have also set both bundle policies in javascript and webrtcbin to max-compat.
g_object_set(G_OBJECT (webrtc1), "bundle-policy", GST_WEBRTC_BUNDLE_POLICY_MAX_COMPAT, NULL);
var rtc_configuration = {
bundlePolicy: "max-compat",
iceServers: [
{urls: "stun:stun.services.mozilla.com"},
{urls: "stun:stun.l.google.com:19302"}]
};
Offer from chrome:
