What is this talk
Beyond standard use cases
- Cloud Gaming
- Teleoperation
- Censorship Circumvention
- Protocol Bridging
We need more…
- Community
- Education
- Software with no assumptions

MY PERSPECTIVE

5.
2
Motivations
Developers are smart, they need to be empowered
* knobs for learning and tuning
Developers find happiness from owning their projects
* I want to promote others, not under Pion umbrella
The more users the better. Even if they aren’t open source
Developers want to be involved in Open Source.
* Companies/maintainers don’t want to share

WebRTC for the Curious
Book on how WebRTC really works
- Not just about the public APIs!
- Deep dive on protocols
History of WebRTC
- Interviews with RFC authors
WebRTC in practice
- Debugging every piece
- Teach the sharp edges

7.

Pion
Collection of Go RTC libraries
- Building blocks to build your vision
- Designed to be flexible
PeerConnection API in Pure Go
- CreateOffer/AddTrack/….
- User controls media pipeline
- SettingEngine
- Interceptors

8.
5
Pion
TURN as an API in Pure Go
- Callbacks for authentication
- Bring your own logger
- Run TURN and HTTPS on same port
- Embed TURN in application
Ion
- Cluster based system for building RTC
- SFU Instance
- AVP Instance (Processing real-time media)
- LIVE Instance (SIP/RTMP/HLS Endpoints)

9.
WHY SHOULD I USE PION

10.
6
For all skill levels
PeerConnection API you already know
Language that gets out of your way
- Memory Safe
- Easy to code and deploy
“typically, fairly young, fresh out of
school ….. the language that we give them
has to be easy for them to understand
and easy to adopt.” - Rob Pike

11.
7
For all skill levels
Get the support you need
- WebRTC for the Curious
- Pion Slack
DevOps friendly
- Go is easy to hire for
Knobs when you become the expert
- SettingEngine/Interceptors
- You can replace any module (ICE)

12.
8
Portable/Flexible
Servers
- Windows/Linux/FreeBSD
- x86/x64/ARM
- Static Binary (Don’t need Go on server)
Mobile
- Android/iOS
- Generate shared object + header file
Small(ish) Platforms
- 3Mb
- TinyGo someday? Arduino, Gameboy Advance!?
Web (WASM)

13.

Features
STUN/TURN
DataChannels
Simulcast
Congestion Control (v3 Interceptor)
FEC/NACK (v3 Interceptor)
getStats API

14.
10
Performance

15.
11
Pion Specific APIs
SettingEngine
- ICE-Lite
- Answering DTLS Role
- Set UDP Port Range
- Interface Filtering
- Static Public IP
- Enable/Disable mDNS Candidates
- ICE Candidate Selection Rules

16.
12
Pion Specific APIs
Interceptors
- Process Inbound/Outbound RTP
FEC
Congestion Control
- Choose between REMB/TWCC
- Tweak REMB Algorithm
JitterBuffer
- You choose the latency/loss tradeoffs

17.
WHAT CAN I BUILD

18.
13
SFU
Simple as AddTrack/OnTrack
- Copy buffers between PeerConnections
PeerConnection for each Client
- Unified Plan and Re-Negotiation
You decide your Congestion Control
- Are you working with embedded?
- Do clients support Simulcast?

19.
14
MCU
Calling C from Go is painless
People use ffmpeg, GStreamer or libvpx
directly

20.
15
Cloud Gaming

21.
16
WebRTC Load Tester

22.
17
Teleoperation
DataChannels more powerful the you expect
- Don’t finish a damaged datagram
- Backpressure info is valuable
Corporate networks are no fun…
- TCP (or TLS) Only
- Proxy required
- UDP Port Ranges Whitelisted
