Hi , checking if any updates on this issue?

23

Hey @Hong,

No updates quite yet.

Thanks!

Oh, ok. Hope they found the resolution soon. I noticed that during our zoom session, there also a short black screen when I pin manually as well. There must be an issue with the pin video frame buffer.

I meant the issue is also with the current up-to-date version of zoom 5.8.3(1581) . Obviously it is an issue across the board. Please do not ignore this complaint it won’t go away by itself.

Thanks

Hey Michael & Jon ,
Wonder if you folks seriously meant to investigate into this matter? It has been so long since I brought up the issue in the development forum

Hi @Hong,

Thank you for your patience as we continued looking into this issue. After extensive investigation, we have determined that this is a side effect of the SDK’s pinning implementation allowing for scenarios in which you can pin the video of a user whose video is not currently subscribed.

When using the Zoom Client, you can only pin a user whose video is active on your screen. This means that the client has already successfully subscribed to that user’s video. However since the SDK allows you to pin by user IDs, it is possible to pin the video of someone who is not already visible. As a result, there is a delay between when the SDK is told to pin a user and when the SDK starts receiving video for that user.

Please let me know if you need any additional information and I’ll be happy to help.

Thanks!

Oh,

Is there a way to work out this issue. Checking if the Client has received the user’s video before it pins?

Also, how come it is not an issue when I use the spotlight function?
Because the Pining function is more suitable for my app , I am hoping your engineers can help me with this.

Hi @Hong,

Is there a way to work out this issue. Checking if the Client has received the user’s video before it pins?

Unfortunately the default meeting UI does not provide a ton of insight into the state of individual user’s videos since it is all managed internally to the SDK. This level of information would only be available in a custom meeting UI.

Also, how come it is not an issue when I use the spotlight function?

The core functionality of spotlighting works differently than pinning users, so the SDK implementation actually uses a different type of view to manage spotlit users.

Thanks!
