Description
A clear and concise description of what the question is.

Hello, I’m using Windows Fully Customizable SDK. And I want to show video frames of a session on window. I already got success for ‘joinSession’ code. After create the session, I want to show it on the window by using window functions, such as ‘WNDCLASSES’, RegisterClassEx(&wndclass)’, ‘CreateWindow(…)’.

Please let me know about the flow of showing the video frames of the session on window.
Thank you.

Hey @tlol91,

Thanks for using the dev forum!

The SDK will provide the video stream as individual frames. To begin receiving frames for a specific user please follow the steps here: https://marketplace.zoom.us/docs/sdk/video/windows/essential/render-video.
When you start getting the frames from

onRawDataFrameReceived(YUVRawDataI420* data_)

You will need to render the YUV frames into your desired window handle. We suggest using a rendering library for this, as it can get quite tedious to do this yourself. Microsoft suggests using their library DirectShow

Thanks!

Thanks for your reply. I have one more question. Where do I need to call ‘onRawDataFrameReceived’?
Now, I succeed to call ‘err = pPipe->subscribe(resolution, this)’.

But I don’t know where and how to call ‘onRawDataFrameReceived’. Please let me know. Thank you.

Hey @tlol91,

onRawDataFrameReceived is a callback and will be called for you when a frame is received. You just need to implement the function and set the event to listen for it.

Thanks!
Michael
