LiveKit Community

there’s a new `canPublishSources` permission where you can specify which track-sources a participant is allowed to publish!

Hi, is it possible to send webhook events with multiple api-key? The reason is I want to change the production api-keys and I can define multiple keys in the values but i can’t see a way to use both keys in webhooks. Is it something you planning to do?

Hey <@U032TUAL4KT> — we haven’t gotten around to this yet. cc <@U02MC5V3C2H> for visibility

while I have you here, what are you interested in using this API for?

Room related data.
• Total Number of participants
• Participant data (the more info we have on each the better it'd be)
    ◦ Main Ones would be
        ▪︎ Participant Join Time
        ▪︎ Participant Left Time
        ▪︎ Duration (Although this can be handled with the previous two metrics)
        ▪︎ Server Region Connected
        ▪︎ SDK used (This could be useful for debugging for clients which have different versions of application)
    ◦ Bonus:
        ▪︎ Track Subscriptions for each participants
        ▪︎ Participant's published track info
        ▪︎ Any Participant Connections details present in the Cloud Dashboard
        ▪︎ Call Quality for the participant
• Room duration
• Room bandwidth consumption 
I can think about this some more, but any information which could become billing metrics for clients of LiveKit. As a a LK Client, then we can charge our own clients based on the data the API would be returning.

This said, thanks for the update <@U01KZ0SCDKL>.

thanks for the detail Pat. Are you planning to charge your customers using a usage-based model?

That is the plan. I haven't flushed out the exact details but I'm looking to implement a per participant x room duration calculation model. I think the pay-per-usage vs Tier would be more beneficial for our clients.

Hey <@U01KZ0SCDKL>, I know you guys have a lot on the go, and a lot of priorities, so I can totally understand. This said, a while back I remember someone else asking about this feature and you would be returning with an ETA, simply curious to know if any thoughts had been put towards this yet or not.

I'm asking simply to know how high or low would this be for you guys and if I should try to plan out an alternative for the time being.

No, we haven’t fleshed this out yet. The team has been slammed with other things. I’ve mentioned <@U02MC5V3C2H> so he can take this back and figure out where it fits into our roadmap. My sense is that it’s on the _lower-end_ of priorities at the moment.

Thanks a lot for the quick update Russ. Appreciate it.

<@U032TUAL4KT> what if you just had, for each room:
• room name
• session id
• total participants
• room duration
• bandwidth used
would that be useful for you, or do you really need per-participant data for the pricing model you want to implement?

nvm, sorry I didn’t see your other message about the room x participant model

<@U02MC5V3C2H> I think that would be a great starting point. The participant data would eventually be needed because the goal was to price based on participants + duration. 100 participants watching 1 participant wouldn't be the same cost as if we had 100 participants sharing their mic and video

So we actually do have a kinda hacky “api” that you can use for this. We shipped it with little fanfare, but now the Sessions and Participants tables in the Cloud UI have a `CSV` link that you can use to download a CSV of that table. These links are generated with each call and they only include data for rooms from the last 14 days.

Without the UI, could someone pull those through a specific url?

Lets say, someone would have a cron running every x, to download the data and import it on their end

so you can download the CSVs in URLs like these:
• `<https://cloud.livekit.io/api/projects/>&lt;YOUR_PROJECT_ID&gt;/sessions/closed/csv` — details for closed rooms
• `<http://cloud.livekit.io/projects/|cloud.livekit.io/projects/>&lt;YOUR_PROJECT_ID&gt;/sessions/&lt;ROOM_ID&gt;` — details for the participants in a given session

now the hacky bit is that if you want to grab those automatically you’ll have to spoof your own session token, which you can copy from your browser cookies for your <http://cloud.livekit.io|cloud.livekit.io> session

… and, hm, now I’m looking at that and the latest version of Chrome actually makes it harder for a user to get at the actual cookie values :confused:

Ahh gotcha. I see. Yeah, the authorization part might be the hardest to do.

Wonder if on the cloud we could use ssh keys auth

Is the unofficial api which you were talking about is this accessible for LK clients? Or rather in closed state atm?

So the hacky thing you can do for now is, grab your `__Secure-next-auth.browser-session-token` cookie from your browser session and save those as the cookies you use from your http client to fetch those CSVs. I believe that session should be valid for 30 days

Don’t quite understand your last question there

Oh sorry I had misread one of your previous message. My bad.

I might just give this "hacky" api a shot and see.

Let us know how it goes! Note that if you have very  many rooms, the sessions csv might take a while to load, so make sure your http client isn’t timing out

Can we pass filters to those links? Per say get only the last 12hrs

This said, I think my approach would be to leverage the livekit-cli on room disconnect to automatically fetch the data, so id be per session and not overall sessions.

just checked, the csv doesn’t support filters

grabbing session data on room disconnect sounds like a good approach!

<@U02MC5V3C2H> Just want to report something. It seems like the CSV works, but seems to have an issue with participants tracks returning `[object Object]`

And if I may ask for a feature request:

`<https://cloud.livekit.io/api/projects/>&lt;YOUR_PROJECT_ID&gt;/sessions/&lt;SESSION_ID&gt;/csv`  Endpoint which could simply provide the single row of that session_id

Also since we're talking about it, the closed sessions CSV, If it could include the `started_at` just like active already includes would pretty neat.

Again, Thanks a lot for all your help <@U02MC5V3C2H>. Ill keep you posted how this works. Copying the token shouldn't be much of an issue.

if you’re using Chrome, this settings flag is useful for grabbing the cookie value

<https://stackoverflow.com/questions/75644703/google-chrome-does-not-show-cookie-values-anymore>

Yeah well I can still see them fairly easily through browser inspect.

I think the usecase <@U032TUAL4KT> outlined here is almost the same we have. We have for now resorted to a hacky workaround using `webhooks` , but that has its drawbacks. Being able to get the data as csv or JSON payload returned from an API call would make my life a lot easier in this regard.

thanks for sharing this <@U04QG2YN6CV> — fwiw, we’re discussing internally how we can provide something more official sooner rather than later.

<@U01KZ0SCDKL> Thanks and wonderful news Russ!

hi, <@U02MC5V3C2H>, can you please explain, "...or maybe re-use the `livekit-cli` auth..."

<@U01KZ0SCDKL> Sorry to be pesty, but any news on this? :innocent:

If we could get a token without manual intervention, the csv solution Noah Tye described above would really go a long way (at least for us).

Hey Sebastian, we'll need to add this to the docs, but we now have a couple of APIs that would allow you to get JSON responses back.

*Listing sessions (last 24h)*
`curl -H"Authorization: Bearer &lt;token&gt;" <https://cloud-api.livekit.io/api/project/>&lt;projectID&gt;/sessions`

*Getting details of a single session*
`curl -H"Authorization: Bearer &lt;token&gt;" <https://cloud-api.livekit.io/api/project/>&lt;projectID&gt;/sessions/&lt;sessionID&gt;`

The token required here is just a standard LiveKit Access Token. It should contain the grant `roomList` (read-only view of all rooms). You can use our CLI to create a test token:
```livekit-cli create-token --list --valid-for 10000h```

<@U01KZ61GV5Z> I just had a chance to try it and this is indeed incredibly useful!

2 Things I noticed:

1. In the csv download (<https://cloud.livekit.io/projects/>&lt;project_id&gt;/sessions/&lt;session_id&gt;/csv), i saw that you also publish information about the published tracks. Any chance this could make it into the API call payload as well?
2. Not directly related to the new API, but in the csv download, there seems to be an error with serializing the `published_tracks` information

<@U04QG2YN6CV> we are now returning publishedSources info for each participant in the API payload:
```    "participants": [
        {
            "participantIdentity": "u1",
            ....
            "publishedSources": {
                "cameraTrack": true,
                "microphoneTrack": true
            }
        }
    ]```
please let us know if you run into any issues

Awesome, thanks for reacting so quickly!

I have a few questions regarding the behavior of your reports, if you'd be so kind:

• Which field determines if a session is older than 24h? Is it the end time?
• Regarding the `/sessions` call,  do only sessions that have ended get reported or also those that are currently active?
    ◦ If active sessions are listed as well, does the `/sessions/&lt;session_id&gt;` call list participants that are currently joined to a room or only those that have disconnected?
Perhaps some context for these questions is helpful: We intend to use this information for billing our clients on a monthly basis and we are wondering what happens in case sessions are running for extended periods of time.

<@U04QG2YN6CV>
1. Any room created in past 24 hours are listed currently.
2. Both active and closed sessions/rooms get reported
3. Active and disconnected participants are listed in all rooms 

These APIs for getting session data programmatically are great!

I wanted to follow up with - Is there any way to get sessions older than 24 hours ago? I'm interested in getting this data so I can track usage, but I'm worried about some error or outage leading to me missing some session data.

currently we are only returning the last 24h.. but introducing parameters so you can export specific days would be something we'd like to do as well

Question on the data returned from <https://livekit-users.slack.com/archives/C01KVTJH6BX/p1685732102175319?thread_ts=1682016022.044869&amp;cid=C01KVTJH6BX|these two endpoints>. When I hit the first one (listing all sessions) it comes back with a field `sessionId` that looks something like like `RM_1234asdf1B`. When I hit the second one (listing a single session using that `sessionId` , it comes back with a field `roomId` that matches.

Should that `roomId` be called `sessionId` instead?

Similarly, are there definitions about what `createdAt` and `lastActive` from the first endpoint and `startTime` and `endTime` from the second endpoint mean?

Hey <@U050W7KDGCT>, `roomId` and `sessionId` are indeed the same thing. These were internal apis that we exposed and there are still some awkward naming relics there.

`createdAt` and `startedAt` are the same
`lastActive` is either now, or when then room was deleted
`endedAt` is either null, or when the room was deleted

Thanks for getting back to me and clarifying those fields <@U04F14MLUJE>!

Generating the token on the client side doesn't seem to be a secure way, you have to store the api key and secret on the client side.

<@U01KZ61GV5Z> <@U04VDH778AV> do you have any update on this?

<@U04A3E0F3GX> i committed the fix for the bug you reported saturday but there are a lot of projects in flight and i want to be sure the release is stable before we publish anything

<@U04A3E0F3GX> please disable signal_relay for now until the next version is released. Thank you for your patience!

cool thanks I disabled it for now, I will check it later if new version is released.

<@U01KZ61GV5Z> <@U04VDH778AV> Today I upgraded livekit to 1.4.2 and re-tested with `signal_relay true` and experienced the same issue. Can you check it again please?

I also faced the same issue with version 1.4.1 and disabled signal_relay. Following the updates here :slightly_smiling_face:

<@U01KZ61GV5Z> <@U04VDH778AV> can you give me some update on this?

Hey Balazs, we found the issue and it'll be fixed in 1.4.3. thank you for the report!

for reference, the PR with the fix is <https://github.com/livekit/livekit/pull/1721|here>

Thanks <@U01KZ61GV5Z> I will check it out again once it’s released

The server will be able to send Data but participants wont be able to send data.

for me, I do not want client to generate offer with data channel only first

I'm not aware if its possible to disable the data channel completely.

This is probably a <@U01KZ61GV5Z> question.

I am trying to inter-operate LiveKit with other webrtc implementation that does not support data channel

Hey <@U043351G48Y> currently we do require it.. but I'm definitely open to adding support for clients that don't have this capability. Which implementation are you trying to integrate with? if you don't mind me asking

the work was on-hold in last several months, now I plan to pick it up

so the idea is having freeswitch speak to livekit server directly? while you'd handle signaling via a separate process?

I got Pion working with Freeswitch for a test tool

the idea is to introduce a middle man as signalling gateway between LiveKit and Freeswitch, but the media goes between LiveKit and Freeswitch directly

it would be great to have an option in the access token for example disableDataChannel.

right.. so what you are looking for is to prevent the server from opening up data channel to the client in the offer.

it is a bit tricky.. as for the "connection" to be established, we cannot send an empty offer.. the offer would have to contain something

we chose to use data channel as that placeholder.. since we do offer that capability anyways

when Freeswitch acts as a publisher, Freeswitch generated offer without data channel, I expect LiveKit does not add data channel in answer SDP

when Freeswitch acts as a subscriber, I expect offer from LiveKit does not have data channel in it

even if Freeswitch acts as a publisher, livekit would by default still establish a subscriber connection (as we consider that the primary connection to a participant)

the publisher side should work just fine.. because if the offer doesn't contain data channels.. neither will the answer.

when Freeswitch acts as a publisher, the token would be canSubscribe as false

I tested if the canSubscribe as false, there is `NO` peerconnection for subscriber

yeah, that's correct.. if subscribe perms aren't given, we do not negotiate a subscribe connection. so that side should work

the problem is when Freeswitch works as a subscriber

LiveKit first sends offer with only data channel in it

then adds audio/video in later offer/answer

right. if media is available, it should be able to send it down together.. if client protocol version can handle it

so that's worth a try.. I think we'd ignore it if datachannel isn't negotiated.

you mean if the answer does not have data channel. LiveKit is ok?

yeah I believe so. what protocol version do you pass in with your proxy?

<https://github.com/livekit/livekit/blob/master/pkg/rtc/types/protocol_version.go#L53|https://github.com/livekit/livekit/blob/master/pkg/rtc/types/protocol_version.go#L53>

I have not started writing code yet, still in design phase

another question, is it possible to specify which member the subscriber wants to subscribe in the access token?

for example, user B only wants to subscribe user A audio

no. that'd be a protocol message you'd send.

If I may add: <https://docs.livekit.io/client/receive/#selective-subscription> this documentation page might be worth going through.

the idea is, 1) Freeswitch joins a room 2) Freeswitch gets the list of participants in the room, 3) Freeswitch subscribes to one of the participants for example B in the room 4) LiveKit generates offer including one m line for B only

<@U01KZ61GV5Z> and <@U032TUAL4KT> can LiveKit support above flow?

you can <https://docs.livekit.io/client-sdk-js/classes/RemoteTrackPublication.html#setEnabled|RemoteTrackPublication.setEnabled> for exactly this :slightly_smiling_face:

I get this error `adaptive stream is enabled, cannot change video track settings`

right, it does not work in conjunction with adaptive stream. though audio track should work

<@U01KZ61GV5Z> I created component with list of participants using `useParticipants` hook.
And created a function that disable audio on button click.
```participant.audioTracks.forEach((track) =&gt; {
     console.log(track, 'track');
     track.setEnabled(false);
});```
It does nothing. (btw I have `roomAdmin` permission)

you'd want to use `useTracks` and a `useEffect`.  `useParticipants` is not guaranteed to update when tracks are changed

you can join a room with the `hidden` attribute. those participant would not be visible to others and would not trigger `ParticipantConnected`

How can you help me please with a sample code? Where is this hidden attribute

Done, thanks for the help, hidden attribute in the token generation

that is not supported. egress requires livekit server

Capture_2023-04-22-001.png

401 means your token is likely incorrect or expired. can you try generating one with a longer validity?

You can instruct to store it in s3 compatible object storage service or minio with egress service request. Assuming you use RoomComposite you use <https://docs.livekit.io/server/egress/room-composite/#starting-a-roomcomposite|https://docs.livekit.io/server/egress/room-composite/#starting-a-roomcomposite> to pass s3 object storage credentials with file path to store

yes i’ve tried storage to local, and cloud storage, but no file were found. and there’s no error server produce, so don’t know what to do next

You need to check egress service log in debug, that should produce the errors. Check egress service repo sample config for reference: <https://github.com/livekit/egress#config|https://github.com/livekit/egress#config>

Hello all,
I am trying to install livekit-cli on window 11 but unable to intsall. can someone help?

I have download .exe zip folder from the github but it's not showing me installation wizard when I am clicking on .exe file

I’m not the decision-maker here, but I think this is fair feedback. You’re definitely not dumb. addGrant could have an interpretation that there’s a side-effect or stateful change happening.

<@U054BDGPTC6> you are right this is not intuitive. this is on me picking add instead of something sane like setGrant.

in the next major version I do agree we should change it. if you are up for making a PR, I would welcome it.

Would suggest:
• marking addGrant as deprecated, so it warns
• have a field `grant` (or simply `set grant(...)`


I’d love to but for the upcoming three months I am absolutely swamped with work. If at the end of July this is still open I’ll very happily pick this up, though.

Pls thread your messages :pray::skin-tone-4:  

<@U054E6M4X6G> you can set it as a piece of participant metadata.

<@U01KZ61GV5Z> Is it possible to add room's metadata when creating room when first participant joins?
Or I have to add metadata only with `UpdateRoomMetadata` or first create room with metadata and then allow participants to join to the room?

You can set the metadata field when calling `CreateRoom``

<@U01KZ61GV5Z> leave button in controlbar component

got it, this is also referring to the component framework for JS. we'll take a look

Hello everyone. I am new But i really appreciate your work guys its exceptional. i just wanted to run the meet kitt or <https://github.com/livekit-examples/kitt> application locally on my machine but was not able to run the lkgpt service. any help would be deeply appreciated

I figured out my issue:  `GOPATH` was not defined in the environment.

Also updated wire:
```go install <http://github.com/google/wire/cmd/wire@latest|github.com/google/wire/cmd/wire@latest>```

livekit uses hostNetwork=true in helm deployment. Autopilot don't support worker node hostNetwork binding, thus the error.

hmm got it
so i have to use a cluster without autoscaling, right?

autopilot and autoscaling are not quite the same. you should be able to use both HPA and cluster autoscaling

Sorry to bump dead thread, have the same situation. <@U01KZ61GV5Z>, could you clarify the next steps here?

<@U02C10ZEP8R> The connection quality stuff does not interfere with streaming. Yes, it is more reactive and is not as optimistic as before (the previous version was a bit too optimistic :slightly_smiling_face: ), but it does not impact quality.

It is possible that some bad update sneaked into the release. There has been a bunch of work and it is possible that a bad commit sneaked through. Sorry about that. We will look at making another release soon.

<@U02CM28PB4Y> Do the connection quality changes only affect the indicator? I assumed it also affected what layers were chosen and when/if to pause video streaming.

No, it is only the indicator.

But, there were some good chunk of refactoring to add upcoming support for more video codecs like AV1/VP9. We found some issues with that under some conditions. My guess is that the release caught a bad commit.

Gotcha. Okay, I'll just stay on 1.3.5 for now and will keep an eye out for updates. Thanks!

<https://docs.livekit.io/server/webhooks/#egress-started|https://docs.livekit.io/server/webhooks/#egress-started>

There is a third webhook not listed in the docs, `egress_updated`

Upload location can be found in the egress ended webhook, and stream success/failure can be found in the egress updated webhook

`egress_updated`  interface is also typed in the client sdk ? if not in the docs

I'll have to double check the sdk, but it should be

got it , thanks <@U01UB0LHTTQ>
also was reading thru the src code , really clean implementation throughout
also read thru the psrpc repo (gRPC is the way to do :rocket:)

Hey Raju, you would use permissions to accomplish this. For listeners, initially you would not grant them publish permissions. Then make those grants with an <https://docs.livekit.io/server/room-management/#updateparticipant|UpdateParticipant> API call.

Hi,
I also posted an answer on github, but just remove the `connect` from your import list and you should be fine!
• sure, you can use Vue 3 with LiveKit. We are currently building a higher level <https://github.com/livekit/components-js|components framework> on top of the client-sdk-js that might eventually also get Vue 3 support (right now we only support react directly)
• AFAIK there’s currently no dedicated Vue example, but<https://github.com/livekit-examples| many examples with react >and there’s also an “example” folder in the client-sdk-js
• see above

<@U02EU2ZPTQU> Thanks for the reply. But I have to use "connect"?
```await room.connect('<ws://localhost:7800>', token);```
So I can't use <https://github.com/livekit/components-js|components framework>.
Still the examples are with react only.
So there is no way to implement with Vue 3?
Really difficult to understand the docs.
The closest I found is this: <https://github.com/livekit/client-sdk-js/tree/main/example>

And even that is not applicable to livekit-client because it imports everthing from index.ts not from the library.

Can't Livekit supply a simple Vue 3 app example? If possible it shouldn't take much time.

&gt; ```await room.connect('<ws://localhost:7800>', token);```
`connect` is being called as a method on `room`

```const room = new Room()
await room.connect(...)```
for the example you linked, just replace `./index.ts` with `livekit-client` it has the same imports.

is there anything in particular that you have trouble understanding in the docs?

Thanks for the reply. I keep having errors and troubles. It'd be greate if we had a simple example using Vue or just TypeScript.

I know it is too much to ask but it'd be beneficial for everyone looking for an example out there.

Once I understand, I can create an example for Vue 3 as well. I just can't get it working yet.

I did replace `./index.ts` with `livekit-client` but it gave me type errors just like connect. There are 4 imports that don't exist in livekit-client.

• RoomConnectOptions
• RoomOptions
• VideoCaptureOptions
• VideoCodec
These don't exist.
```SyntaxError: The requested module '/node_modules/.vite/deps/livekit-client.js?v=263c77b9' does not provide an export named ... ```

Look at this code for example:
```function handleTrackSubscribed(
  track: RemoteTrack,
  publication: RemoteTrackPublication,
  participant: RemoteParticipant
) {
  if (track.kind === Track.Kind.Video || track.kind === Track.Kind.Audio) {
    // attach it to a new HTMLVideoElement or HTMLAudioElement
    const element = track.attach();
    parentElement.appendChild(element);
  }
}```
What is parentElement here? It doesn't say anywhere here: <https://github.com/livekit/client-sdk-js>
 It is very difficult to understand the docs.

```&lt;script setup&gt;
import {
  Room,
  RoomEvent,
} from 'livekit-client'

import { ref, onMounted } from 'vue'

const token1 = 'user1 token'
const token2 = 'user2 token'

const room = new Room()

const localVideoContainer = ref()
const remoteVideoContainer = ref()

onMounted(async () =&gt; {
  await room.prepareConnection('<wss://live-dev-k5mhurx4.livekit.cloud>')

  room
    // publish local video and display it to localVideoContainer
    .on(RoomEvent.LocalTrackPublished, function (publication) {
      const track = publication.track.attach()
      localVideoContainer.value.appendChild(track)
    })
    // subscribe remote video and display it to remoteVideoContainer
    .on(RoomEvent.TrackSubscribed, function (remoteTrack) {
      const track = remoteTrack.attach()
      remoteVideoContainer.value.appendChild(track)
    })

  await room.connect('<wss://live-dev-k5mhurx4.livekit.cloud>', token1)
  await room.localParticipant.enableCameraAndMicrophone()
})
&lt;/script&gt;

&lt;template&gt;
  &lt;div ref='localVideoContainer'&gt;&lt;/div&gt;
  &lt;div ref='remoteVideoContainer'&gt;&lt;/div&gt;
&lt;/template&gt;```

this is a minimal example to publish local video, you can create two vue template projects and paste those code to HelloWorld.vue.

• npm create vite@latest my-vue-app -- --template vue
• get your livekit-server url with cloud one, or host your local one <https://cloud.livekit.io/>
• the app key and secret can be generate with cloud settings page, or use self hosted $bash livekit-server --dev
• get your token with cli
• for more client sdk room events, <https://docs.livekit.io/client-sdk-js/enums/RoomEvent.html>
• like <https://docs.livekit.io/client-sdk-js/enums/RoomEvent.html#LocalTrackUnpublished|LocalTrackUnpublished>, <https://docs.livekit.io/client-sdk-js/enums/RoomEvent.html#TrackUnsubscribed|TrackUnsubscribed>, you can detach video audio, do some cleanup on unmount event etc…
```livekit-cli create-token \
    --api-key apikey --api-secret apisecret \
    --join --room room1 --identity user1 \
    --valid-for 720h

livekit-cli create-token \
    --api-key apikey --api-secret apisecret \
    --join --room room1 --identity user2 \
    --valid-for 720h```

I have found the similar issue like yours.
In my case, i only record the host, and disable rest participant.
I change record template to single-speaker, but you might want to record the others tracks.
there’s custom template <https://docs.livekit.io/server/egress/room-composite/#default-layouts>

this will lead a grayish box with grid template

only recording the host is the problem for me. I need to record every participant who broadcasts  and they should be in one video.

do they turn on the camera? if the camera is enabled, i think its bug somewhat

If they want, the camera can be turned off but the sound can be turned on, the camera and microphone can be turned on, or both can be turned off.
If they don't want to publish anything, the unpublishAllTracks function is triggered.

Actually, I had to revert to make it work.

does it work on 1.2.1 if you use `https` instead of `wss` in your server url? (the server-sdk is based on http requests and not on websockets)

thank you for the report! I think we should normalize these parameters within the SDK itself.

hi <@U055T3944JU>,
that’s definitely not expected!
A couple of things to track this down
• Are you using cloud/self hosted instance? in case of self hosted, can you check if the same thing happens when using <http://meet.livekit.io|meet.livekit.io> with the custom connection option and provide your server url and a token
• which components version are you using? (please update to the latest npm version in case you haven’t)
• Could you post the logs you’re getting?
• Does the parent component constantly re-render for you ? (just put a console.log(“render”) in the component  above `&lt;LiveKitRoom&gt;`


The component is constantly rerendering, but the one that is is the LiveKitRoom itself and the offending prop is `children`

This is currently in an extremely barebones app and there is virtually no difference from your example code

I see 1.0.0 was _just_ released so will try that

No dice here is our page (video works totally fine the only issue is the rerendering)

My profiler is saying that `token` is causing a rerender, but this code looks just like your examples and I'd expect your hook to only return once

Hi <@U02EU2ZPTQU>, I'm working with Jamie on this issue as well and want to add some things in case it's helpful for debugging. We're using <https://github.com/livekit/components-js/blob/main/packages/react/src/hooks/useToken.ts|this hook> to fetch the token almost identically to have livekit does it in livekit meet <https://github.com/livekit/meet/blob/8b68ac904228b060f703dbf79776a7129fbfe87f/pages/rooms/%5Bname%5D.tsx#L69-L74|here>.

That `useToken` hook is running over and over again, and you can see the `log.debug('fetching token');` show up multiple times in the logs Jamie included. Is there anything we should be looking out for that might cause `useToken` to get called on a loop continuously?

in your `useToken` implementation, can you try to replace the `options` in the dependency array with `[tokenEndpoint, roomName, JSON.stringify(options)]` .
this would prevent causing re-renders (and we’ll probably add this optimization to the components-js repo as well)

<@U022KB72NFJ> I have also just sent you a direct message with a build of the same app shown above to test out if you'd like.

Matt, are you using adaptiveStream by any chance? can you try it with adaptive stream disabled?

I am using the default settings for LiveKit Unity WebGL SDK. Is adaptive stream enabled by default?

Hey guys, I have experienced this behaviour with remote video tracks on Safari (MacOS) but hadn't seen it on other browsers, <@U022KB72NFJ> is it possible that the fix you have done would work in this situation also?

Hey, can you see if finding the video element inside the DOM (Should be inside body) and calling video.play() inside it fixes the issue?

Hey, can you try the <https://github.com/livekit/client-sdk-unity-web/compare/main...theo/videotest|theo/videotest> branch?

Hi <@U022KB72NFJ>, had to do a bit of fiddling around to get my project to work with the source code as I was using the package, but it seemed to solve the problem. Subscribing to new remote video tracks that are added after joining a room seemed to play automatically in Safari now

Hey <@U022KB72NFJ>, I am primarily a Unity C# developer so I'm a bit out of my element as far as digging into this issue myself, but if given specific code snippets to use I can test out bugfixes and see if it works. Should I replace my version of `livekit-bridge.jslib` with <https://github.com/livekit/client-sdk-unity-web/compare/main...theo/videotest|the one you linked> above and see if it helps?

Happy to do whatever I can to help get to the bottom of the issue.

2023-05-01_Screen_Share.png

We did use screen share for an internal meeting today and besides the black screen issue it functioned quite well to do a design review of a new "world" we are building. :slightly_smiling_face:

2023-05-01_Screen_Share_Black.png

However we do need to fix this bug before releasing the screen share feature publicly because currently users are usually met with a black screen until the window is resized (and our users wouldn't know to do this).

I know you are juggling a few different priorities at the moment <@U022KB72NFJ> but when you are available to take a closer look, I am happy to help any way I can to get to the bottom of it.
