skyway-webrtc-gateway

This is the old SkyWay repository. Please consider migrating to the new SkyWay.

SkyWay WebRTC Gateway is an experimental approach to expand WebRTC possiblity. We're seeking new partners who challanges innovation.

Concept

The mission of SkyWay is to make everyone use WebRTC easily. At first SkyWay starts to provide signaling to browser, then extends the device support to iOS and Android. As a next step, in order to the range of device and use case, we developed the SkyWay WebRTC Gateway which is IP reachable.

Background

WebRTC Engine inside the browsers is only controlled by the browser's API. Control via JavaScript is the condititon.

Because of this, you might have the problem like:

You want devices to use WebRTC but the devices is not capable of running browser
How can we operate the IoT device outside?
I want to analyze the video with AI or to send data...
I want to use WebRTC on server-side but the headless browsers doesn't meet my requirements...
Can we make use of SIP/RTP property we already have?
etc...

What if there's a WebRTC Engine which can be controlled by the program? This can leads to develop software or service freely...

In order to meet this needs, previously there's limited ways like developing something with libWebRTC from scratch, OpenWebRTC, or Janus. However, it's really difficult to understand the library and to develop application. In addition, before your starting production service there are other problems like:

Usability of existing application is different from the browser's one
You need to prepare signaling and TURN server
You can not get enough support from developers

Functions

To solve these problems, we have developed the SkyWay WebRTC Gateway which equips WebRTC engine which is wrapped with SkyWay. There are functions below:

You can use SkyWay as you do
- Signaling server, TURN server
- Controll the application with REST API which is similar to existing SkyWay's API
You can inject data to SkyWay WebRTC Gateway from outside
- Send RTP to SkyWay WebRTC Gateway and the remote party can recevie it as MediaStream
- Receive RTP which is sent by remote party is originally MediaStream
- Send UDP and inject it to DataChannel
- Receive UDP which is originally DataChannel
- DataChannelで届いたデータをUDPで受け取る
Because SkyWay WebRTC Gateway runs as stand-alone application, low performance devices can use it

How to use

At first you need to use REST API, then you establish WebRTC sesssion. After this, what you need to do is send RTP or UDP to SkyWay WebRTC Gateway via established session from your program. Lots of use case should be covered. For instance, you can inject the video to recording device, or you can send control signal to the device which in behind the firewall.
