webrtcbin usage [feature request]

[ldenoue]

First, thanks for creating this NodeJS bindings for GStreamer. Lately, I've discovered the rather new webrtcbin element and wondered what we need to add to gstreamer-superficial to make it usable here.

For reference, here's a python sample code (simpler to understand) that shows interactions with this webrtcbin element: https://gitlab.freedesktop.org/gstreamer/gst-examples/-/blob/master/webrtc/sendrecv/gst/webrtc_sendrecv.py#L129

In particular how could we modify the cpp wrapper files used by gstreamer-superficial to add these:

GstSdp.SDPMessage.new GstSdp.sdp_message_parse_buffer GstWebRTC.WebRTCSessionDescription.new Gst.Promise.new

And also can we emit things to the webrtc element, like done in https://gitlab.freedesktop.org/gstreamer/gst-examples/-/blob/master/webrtc/sendrecv/gst/webrtc_sendrecv.py#L133

I'm aware this would make it less superficial ;)

I would love to see this and thank you for doing some research of (some of) what would be required.

Currently, gstreamer-superficial isn't well setup to support this. We would have to be able to (at least)

• send and receive signals,
• instantiate and connect individual elements
• support Gst Promises

This could add some basic webrtc functionality to nodejs, which would be awesome. People would expect a similar interface to the browser's interface to WebRTC though. Maybe https://github.com/node-webrtc/node-webrtc is a solution?

I am happily using gst-webrtcbin in some other projects (not with nodejs), so maybe someday... :)

@ldenoue, FYI: I had the same need and got it to work using node-gtk instead following this C implementation as an example. These examples of working with gstreamer through node-gtk were also very helpful in the process.
