# ice-tcp
|
||||
ice-tcp demonstrates Pion WebRTC's ICE TCP abilities.
|
||||
|
||||
## Instructions
|
||||
|
||||
### Download ice-tcp
|
||||
This example requires you to clone the repo since it is serving static HTML.
|
||||
|
||||
```
|
||||
mkdir -p $GOPATH/src/github.com/pion
|
||||
cd $GOPATH/src/github.com/pion
|
||||
git clone https://github.com/pion/webrtc.git
|
||||
cd webrtc/examples/ice-tcp
|
||||
```
|
||||
|
||||
### Run ice-tcp
|
||||
Execute `go run *.go`
|
||||
|
||||
### Open the Web UI
|
||||
Open [http://localhost:8080](http://localhost:8080). This will automatically start a PeerConnection. This page will now prints stats about the PeerConnection. The UDP candidates will be filtered out from the SDP.
|
||||
|
||||
Congrats, you have used Pion WebRTC! Now start building something cool
