Use Cases / Livestreaming

Put the live back in livestreaming

The vast majority of livestreams today use a protocol called HLS. HLS takes advantage of traditional CDNs which are optimized for quickly delivering a sequence of static files. The problem is end-to-end latency; anywhere from 5 to 30 seconds of it between broadcaster and subscriber. LiveKit is a new type of WebRTC CDN, capable of sub-100ms latency for audiences of 1000 or 100,000. True real-time, large-scale events, where anyone and everyone can participate are now possible.

Build the future of participatory media

Live Podcasts

Scale up to large numbers of speakers and thousands in the audience with features like dynamic broadcast and DTX to automatically manage bandwidth, RED for higher audio quality, and listener moderation APIs.

Game Streaming

Capture screen pixels directly from the GPU and ingest streams from multiple players at once. Layer in real-time chat using data messages and record the entire experience directly to your own cloud bucket.

Shopping & Auctions

Import streams in other formats or from any broadcast studio software. Integrate audience interactivity like live chat, reactions, and purchases or bids. Pipe a composite stream to any third-party livestreaming service that speaks RTMP.

MOOCs

Poll thousands of students as a group during lecture and allow anyone to raise a hand and ask a question. Teachers have full control over breakout sessions and lectures can be recorded for students who couldn't attend.

Tools to help you reach a global audience

Connectivity Icon

Adaptive Streaming

Put bandwidth managment on autopilot. These features magically adjust bitrates, resolutions and fps based on changes to participant device profiles, your app's UI or publisher/subscriber-side network conditions.

Multiplayer Icon

Multi-codec Simulcast

Using available bandwidth and capabilities of subscriber devices, MCS dynamically encodes streams with next-gen codecs like AV1 and works with LiveKit server to route them to the appropriate participants.

Envelope Icon

Data Messages

Send and receive arbitrary data messages between participants. Messages can be 1:1 or 1:N broadcasts with options for reliable (TCP) and unreliable (UDP) delivery methods.

List Check Icon

Moderation APIs

Oversee and enforce rules in your app from the backend. Querying or manipulating rooms, altering the state of any participant, or broadcasting data messages to one more clients are just some of the tools at your disposal.

Cross Platform Icon

Ingress

Import audio, video or data streams encoded in other formats or from other systems. Stream static files from the command line, pull in feeds from security or drone cameras, or ingest composite output from broadcasting software.

Recording Icon

Egress and Recording

Record rooms, participants, or individual streams to any cloud storage bucket. You can also export any stream in real-time to another system or service for further processing.
