When there are more than 5 users on the stage (in the room), we’re getting the error in the method “attachVideo”: subscribe video counts greater than maximum size (4) Client: const zmClient = ZoomVideo.createClient(); await ZoomVideo.preloadDependentAssets(`${window.location.origin}/lib`)…

Hey @sergey77 , We are working on an improvement this fall to render more than 4 videos without SAB and with great performance. In the meantime, please use the {disableRenderLimits: true} in the enforceMultipleVideos attribute of the client.init method. Best, Tommy

Hi @sergey77 , I see you have enforceMultipleVideos set to true, but this only allows for 4 videos at max. To allow for gallery view with >4 videos, you’ll need to enable SharedArrayBuffer . Thanks, Rehema

Hi @rehema.zoom , Is there a way to render more than 4 videos with SharedArrayBuffer turned off? In our case, enabled SharedArrayBuffe leads to multiple issues related to CORS

Hi @sergey77 , Unfortunately, over 4 videos cannot be rendered without SAB enabled. Is using serviceworkers, as described here , an option for you all?

Hey @sergey77 We have an exception where you can set {disableRenderLimits: true} in the enforceMultipleVideos attribute of the client.init method. This allows you to render up to 25 videos simultaneously, but enabling this option may cause high CPU usage and video performance issues. Thanks Vic

Hi @rehema.zoom , Our app uses a lot of content (video, images, etc.) from various sources that are not related to us. At the moment, enabling coi-serviceworker breaks the usage of third-party content sources in the app. Is there a way to configure serviceworkers so that it only affects Zoom cont…

Hi @vic.yang , Thanks for a hint. Actually, I don’t think we need support for as many as 25 videos simultaneously. If we use a maximum of 6-9 videos simultaneously, how critical is it for high CPU usage? If the usage of 6-9 videos simultaneously doesn’t create performance issues, then the solution…

Hey @sergey77 If we use a maximum of 6-9 videos simultaneously, how critical is it for high CPU usage? It depends on the performance of different devices. Our initial setting of 4 is conservative. On higher-performance devices (such as a MacBook Pro with an M1 chip), even with more than 10 vide…

Hi @tommy , thanks for the response. We’re looking forward to getting this update. This is really important to us

Hi @vic.yang ,
Is there any development to improve performance when using more than 4 videos without SAB enabled? I read that there is a release planned for August:
