We are planning to use the latest Zoom Video SDK web 2.25  
We have a requirement to apply some overlay using WebGL when receiving video frames (on the video subscribing side). We think [renderVideo](https://marketplacefront.zoom.us/sdk/custom/web/modules/Stream.html#renderVideo) API is what we need. We can use the incoming video frames in a canvas or video element as WebGL textures.  
But `renderVideo` is deprecated and the replacement is [attachVideo](https://marketplacefront.zoom.us/sdk/custom/web/modules/Stream.html#attachVideo). But there is NO public API for us to get the access of the underlying canvas.

Is there a way to access the video stream?

Hey @Hale

Thanks for your feedback.

Currently, we do not support manipulating the video stream on the receiving end. This feature may be supported in a future version.

Thanks  
Vic
