How can I show video frames of a session on window?

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!
Michael
