LiveKit: Real-time video, audio and data for developers

LiveKit is an open source project that provides scalable, multi-user conferencing based on WebRTC. It's designed to provide everything you need to build real-time video audio data capabilities in your applications.

LiveKit's server is written in Go, using the awesome Pion WebRTC implementation.

Tools

Install

Tip

We recommend installing LiveKit CLI along with the server. It lets you access server APIs, create tokens, and generate test traffic.

The following will install LiveKit's media server:

MacOS

brew install livekit

Linux

curl -sSL https://get.livekit.io | bash

Windows

Getting Started

Starting LiveKit

Start LiveKit in development mode by running livekit-server --dev. It'll use a placeholder API key/secret pair.

API Key: devkey
API Secret: secret

To customize your setup for production, refer to our deployment docs

Creating access token

A user connecting to a LiveKit room requires an access token. Access tokens (JWT) encode the user's identity and the room permissions they've been granted. You can generate a token with our CLI:

livekit-cli create-token \
    --api-key devkey --api-secret secret \
    --join --room my-first-room --identity user1 \
    --valid-for 24h

Test with example app

Head over to our example app and enter a generated token to connect to your LiveKit server. This app is built with our React SDK.

Once connected, your video and audio are now being published to your new LiveKit instance!

Simulating a test publisher

livekit-cli join-room \
    --url ws://localhost:7880 \
    --api-key devkey --api-secret secret \
    --room my-first-room --identity bot-user1 \
    --publish-demo

This command publishes a looped demo video to a room. Due to how the video clip was encoded (keyframes every 3s), there's a slight delay before the browser has sufficient data to begin rendering frames. This is an artifact of the simulation.

client-sdk-flutter's Issues

running the provied example failed

Hi, i was trying to run the provided example but failed. the error was:

❯ pod install
Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "WebRTC-SDK":
  In snapshot (Podfile.lock):
    WebRTC-SDK (= 92.4515.07)

  In Podfile:
    flutter_webrtc (from `.symlinks/plugins/flutter_webrtc/ios`) was resolved to 0.2.2, which depends on
      WebRTC-SDK (= 92.4515.07)

    livekit_client (from `.symlinks/plugins/livekit_client/ios`) was resolved to 0.0.1, which depends on
      WebRTC-SDK (= 92.4515.10)

Specs satisfying the `WebRTC-SDK (= 92.4515.07), WebRTC-SDK (= 92.4515.07), WebRTC-SDK (= 92.4515.10)` dependency were found, but they required a higher minimum deployment target.

when i saw the Podfile, the target in the provided example is

platform :ios, '12.1'

which seems right.

i've tried to do pod cache clean --all too.

any suggestion ?

I am using:

  • ios simulator
  • on Mac M1

flutter example can not work with livekit-cli

what happend

flutter example will broken when use livekit-cli publish a h264 file.

2022-02-17-170406_1920x1080_scrot

what did i do

  1. run livekit-server

validate uri constructed wrongly

In logs on my livekit server, I just saw a GET request to /validate. The request was made by the flutter client. The bug is that there is no such handler for /validate. If you look in the server at https://github.com/livekit/livekit-server/blob/61655c6ff05625ecd86557711cec38a4a9f7167d/pkg/service/server.go#L91 you see it's /rtc/validate.

Looking at buildUri, the logic going on there seems far from obvious to me, but it looks to me like it could never construct /rtc/validate.

Unfortunately this sort of bug is very hard to spot because of the way Go's http mux works. What will be happening is that the mux finds the health check handler for / and passes the request to that. It would probably be preferable to remove any / handler and instead have a specific /healthcheck so that this sort of bug becomes more obvious.

For now, I've just hacked my local copy of the server to call the validation handler on both uris, because I don't know whether the correct uri should be /rtc/validate or /validate and I've not checked all the other clients.

CocoaPods could not find compatible versions for pod "WebRTC-SDK":

Getting Below error with livekit latest version 0.5.5 in IOS simulator

[!] CocoaPods could not find compatible versions for pod "WebRTC-SDK":
In Podfile:
flutter_webrtc (from .symlinks/plugins/flutter_webrtc/ios) was resolved to 0.7.1, which depends on
WebRTC-SDK (= 93.4577.01)

livekit_client (from `.symlinks/plugins/livekit_client/ios`) was resolved to 0.5.5, which depends on
  WebRTC-SDK (~> 92.4515)

Solution -

Works fine after upgrading flutter webrtc version and changing client pod spec file as below.

pubspec.yml -> flutter_webrtc: ^0.8.1
livekit_client.podspec-> s.dependency 'WebRTC-SDK', '~> 93.4577.01'

So please bump flutter webrtc version .

running on iPhone 6s iOS 14.8

microphone not published on windows build

When building or running on windows, the localAudioTrack (microphone) doesn't get published.

it doesn't show any errors or warnings, it just doesn't work.

I've tried with LocalAudioTrack.create() + localParticipant.publishAudioTrack()
and also with just the localParticipant.setMicrophoneEnabled(true);

same results.

to reproduce: just run or build the example provided in client-sdk-flutter and check the published audio tracks on the room.

tested on 0.5.5

android: example app doesn't show remote participants video track

when running the example app in android, the remote participants can be heard but not seen.
the remote video track appears as if it was muted.

even if the remote participant mutes/unmutes his video or switches camera, it's never seen on the android app.

btw, the chrome version of the app can see the android video stream without problem.

this was tested on
client-sdk-flutter commit 28e7091
livekit-server commit c00d799ac6ebcfbdf32b48c886801f968a4e62c6

muted mismatch between TrackPublication and its track

When a TrackPublication is muted, I expect it's track to be muted as well

instead I get:
TrackPublication.muted [true]
TrackPublication.track.muted [false]

if that's a normal behaviour, we would need a better documentation on the purpose of track's muted attribute.

tested on v.0.5.3

flutter pub get failed

random video freeze when participant disconnects

description

when a participant leaves the room, some of the remaining participant may randomly experience a freeze on the video track from a remote participant or from his own stream.

how to reproduce

run the client-sdk-flutter/example on three devices (I tried iOS, Android and chrome)
join the same room, then make one participant leave. Then check if all video streams are updating on the remaining participants

if it doesn't occur, rejoin the room on the participant that left, and try again... it will eventually happen.

btw, the audio is still alive, but the video is frozen, it gets fixed if the "frozen" participant mutes/unmutes his video

I think it's related to the visibility events being fired

tested on commit 2b37503

Execution failed for task ':flutter_webrtc:compileReleaseJavaWithJavac'.

Good Day.

I tried running the plugin from a fresh install of latest dev channel for livekit_client: ^0.5.7.

Missing lines of code in 0.5.6

I include in pubspec.yaml for version 0.5.6 and found that some lines of code were missing when compared to what is in GitHub. (as of Jan 27)

For example, in lib>src>participant>local.dart, these lines (line 326 onwars) are missing:

void setTrackSubscriptionPermissions({
required bool allParticipantsAllowed,
List trackPermissions = const [],
}) =>
room.engine.signalClient.sendUpdateSubscriptionPermissions(
allParticipants: allParticipantsAllowed,
trackPermissions: trackPermissions.map((e) => e.toPBType()).toList(),
);

"ConnectException Failed to connect to server" ONLY on iOS with 4G/5G

First I want to thank you for the dev expierence with livekit, it is really awesome. This project is going to huge. :)

My issue is, It just won't connect on iOS with celluar, works fine in every other scenario.

Very strange is that, there is a small chance for it to work, but only after a fresh start of the app. But this happend only 2 or 3 times out of 50-60 trails.

At first I thought that it was an issue withe the celluar provider (telekom) doing IPv6 only, but changing to regular dual-stack did not solve the issue, and also everything was fine when the IPv6 only uplink was used by other devices via hotspot.

Versions:
flutter_client 0.5.9
iOS 15.4.1

What did I test:

LiveKit Connection Test is fine on all devices under all circumstances.

[Bug] - When I start example app and ToggleCamera the app crash

Hi master,
Please follow the following instructions before filing a bug:
Step reproduce:

  1. Run app -> Join a room
  2. Touch button (Toggle Camera)
  3. Result App crash
    Expected: Function change font or back of the camera
    Note: I think the problem may be related to policy and permissions for android version 10 and above.

Example failed to run on ios simulator

Hi there, I am trying to run the example app from the latest main branch but there is an error while compiling for ios simulator. I search the github issues previously and found something almost similar reported before #22 .

The error received was:

[!] CocoaPods could not find compatible versions for pod "WebRTC-SDK":
  In snapshot (Podfile.lock):
    WebRTC-SDK (= 92.4515.11)

  In Podfile:
    flutter_webrtc (from `.symlinks/plugins/flutter_webrtc/ios`) was resolved to 0.7.1, which depends on
      WebRTC-SDK (= 92.4515.11)

    livekit_client (from `.symlinks/plugins/livekit_client/ios`) was resolved to 0.5.2, which depends on
      WebRTC-SDK (= 92.4515.10)


You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `WebRTC-SDK` inside your development pod `livekit_client`.
   You should run `pod update WebRTC-SDK` to apply changes you've made.

I have run every command suggested by the error and the same error is still popping up.

Thank you :)

Full HD resoution

Anyone was able to use this lib using more than 720p resolution? I tried in several ways to setup a 1080p video call but the system never able to use more than 1280x720@30.

Tested using Android, iPhone and Web.

sdk is broken (0.5.9)

The sdk seems to be broken, not even the "example/" would run or compile.

when trying to run the example, there are tons of compilation errors.

Please help i couldn't understand what the problem is, at first i thought it was about giving permissions but my app has permissions for microphone and camera, so i don't know why it's crashing like this on ios.

no speaker setup

hello, i have a request for a speaker, but i can't find it in the sdk

Can't successfully transfer audio when join an existing room for the first time after app open (iPhone)

Describe bug

When app is opened and the client joins an existing room for the first time,
the client can't transfer audio.
The track is published and the client can receive and hear other participants' tracks,
but the client's track can't be received by other participants and localParticipant.isSpeaking is always false.

And if the client disconnect and then connect again,
the above problem won't occur.
Also, if the client creates a room, the above problem won't occur either.

Version

client: flutter, 0.5.8
server: k8s, 0.15.5

How to reproduce

Use flutter example app.
Create a room on a device or emulator.
On an iphone 13 mini emulator, join the same room and publish audio.

This problem won't occur on Android.
It seems to be that the microphone won't get activated for the first time.

Screenshots

open app for the first time and joins an existing room

disconnect once and joins the same room again

publishData results in TimeoutException on mobile platforms

Problem

For some reason publishData method of LocalParticipant class fails to send message on mobile platforms (iOS/Android), although it works fine on web: during the connection to the same room participants receive messages sent by users connected with web versions of the app, while messages sent by mobile clients never received by any participant.

During the debug stage on mobile devices the clicking on send demo data button results in TimeoutException after some delay:

E/flutter (17084): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: LiveKit Exception TimeoutException Timeout

Reproduce

This behaviour can be reproduced with the example from this package.

Additional

I checked LiveKit deployment with LiveKit Tester (https://livekit.io/connection-test). Everything seems to work fine (all tests passed).

Flutter version: 2.10.5

Is there a listener for video freezing?

Good Day.

Thank you for this plugin, best webrtc implementation yet so far. However, I am running issues of client video freezes due to lag. Is there any listener for video freezing? I have already used RoomReconnectingEvent and RoomReconnectedEvent. I even tried using ParticipantConnectionQualityUpdatedEvent for both publisher and local participant to show loading, whenever connection drops to poor. However, I am still seeing cases wherein connection is good, but video freezes due to lag.

Thank you.

publication.dimension not working

when I print out the publication.dimension for every participant, it always returns width:0 height:0
I've tried it on web and android, both have the same behavior.

I think it used to work fine in previous versions.

testing it with:
livekit-server 0.14.2

I deployed a k8s cluster, and the example web application works fine without server error.

The connection test is passed.

However, when I used the flutter client sdk, the server gave the following error when connected.

VideoParameters not exported

There are no VideoParameters (or VideoParametersPresets) available in the package.

It's missing an export 'src/types/video_parameters.dart'; on livekit_client.dart
note there are other src/types files not being exported, but I'm not sure if they all need to

tested on v0.5.9 (main doesn't seem to have it either)
