* Handle an edge in layer lock. A very edge case - Available layer: [0, 1, 2], but bitrate is not yet available. We set it to layer 2 awaiting measurement. - Measurement for layers 0 and 1 come through. - Still no key frame for layer 2. - Finalize layers runs and sees that bitrate is available for 0 and 1. It finalizes layer 1. - Layer 1 key frame comes (because we asked key frame of layer 2, publisher sends key frame for all layers). Locks to layer 1. - No more events happen to switch to layer 2. Changes ------- - Move bit rate measurement to StreamTrackerManager. Allows re-use in relay. - Make bit rate availability (from zero -> non-zero) an event and let it flow through the stream allocation flow so that we always have an event when bit rate measurement becomes available. This gets rid of finalization which I was unhappy with it anyway as it was polling every second. - Removing REMB stuff from buffer. We do not use it. It is incorrect anyway. REMB should be ay peer connection level. * Fix test * fix test * Simplify allocate * Simplify/clean up
LiveKit - Open source, high performance WebRTC infrastructure
LiveKit is an open source project that provides scalable, multi-user conferencing over WebRTC. It's designed to give you everything you need to build real time video/audio/data capabilities in your applications.
LiveKit is written in Go, using the awesome Pion WebRTC implementation.
Features
- Scalable, distributed WebRTC SFU (Selective Forwarding Unit)
- Modern, full-featured client SDKs for JS, React, iOS, Android, Flutter, and Mac
- Built for production - JWT authentication and server APIs
- Robust networking & connectivity. UDP/TCP/TURN
- Easy to deploy - single binary, docker & kubernetes
- Advanced features - speaker detection, simulcast, selective subscription, moderation APIs, and webhooks.
Documentation & Guides
Docs & Guides at: https://docs.livekit.io
Try it live
Head to our playground and give it a spin. Build a Zoom-like conferencing app in under 100 lines of code!
SDKs & Tools
Client SDKs:
Server SDKs:
- Javascript (docs)
- Go (docs)
- Ruby
Tools:
- livekit-cli: command line admin & tools
- chrometester: load testing with headless-Chrome bots
- docker image
Quickstart
Generate config file and keys
docker run --rm -v$PWD:/output livekit/generate --local
The above command generates a livekit.yaml you can use to start LiveKit. It'll contain an API key/secret pair you can
use with your LiveKit install.
Starting with docker
docker run --rm -p 7880:7880 \
-p 7881:7881 \
-p 7882:7882/udp \
-v $PWD/livekit.yaml:/livekit.yaml \
livekit/livekit-server \
--config /livekit.yaml \
--node-ip <machine-ip>
When running with docker, --node-ip needs to be set to your machine's IP address. If the service will be exposed to
the public Internet, this should the machine's public IP.
Test with example app
Head over to the example app and enter the generated token to connect to your LiveKit server. This app is built with our React SDK.
Once connected, your video and audio are now published to your new LiveKit instance!
Generating access tokens (JWT)
To add more users to a room, you'll have to create a token for each participant. Learn more about access tokens.
livekit-server provides a convenient sub-command to create a development token. This token has an expiration of a
month, which is useful for development and testing, but not appropriate for production use.
docker run --rm -e LIVEKIT_KEYS="<api-key>: <api-secret>" \
livekit/livekit-server create-join-token \
--room "<room-name>" \
--identity "<participant-identity>"
Deploying to server
Deployment Docs: https://docs.livekit.io/guides/deploy
Single node server
Use our deploy config generator to set up a single node deployment with automatic TLS termination and built-in TURN.
It includes a cloud-init/setup script that's supported by most cloud environments.
docker run --rm -it -v$PWD:/output livekit/generate
Kubernetes
We publish a helm chart that helps you to set up a cluster with high availability. For detailed instructions, see Kubernetes guide
Testing your deployment
Use the connection tester to ensure your installation is set-up properly for user traffic.
Building from source
Pre-requisites:
- Go 1.15+ is installed
- GOPATH/bin is in your PATH
Then run
git clone https://github.com/livekit/livekit-server
cd livekit-server
./bootstrap.sh
mage
