I am looking to run some ML models on raw video data in mobile client SDK. I need to run at 1fps.

I am finding to alternatives. Which approach would be better?

1. feed data from camera via VirtualVideoSource into zoomsdk.
2. do preprocessing of data via  
ZoomSDKVideoSourceHelper sourceHelper=ZoomSDK.getInstance().getVideoSourceHelper();  
sourceHelper.setPreProcessor

I checked, from what it looks like that, video-pre-processor work on inbound video streams.  
ZoomSDKVideoSourceHelper.setPreProcessor

I think VirtualVideoSource might be the only option. Can anyone tell me whats the performance hit of feeding camera feed through virtual video source, what fps would be supported?

Hi @pankajmyt, thanks for the post.

Unfortunately, accessing raw video data requires a raw data license, which is not currently publicly available.

Our [Video SDK](https://zoom.us/docs/en-us/video-sdk.html) provides access to raw data out of the box, but keep in mind that it is not compatible with Zoom meetings. If you would like to give that SDK a try and have any questions, please feel free to reach out in the #mobile-video-sdk category. 🙂

Thanks!

We have our existing system built on zoom meetings. so we would prefer to do it in Client SDK.  
Could I get a test account for me to be able to test this raw-video in Client SDK?

I would be happy to talk to sales, post our POC on this.

Hi @pankajmyt,

Unfortunately it is not possible to obtain a raw data license for the Client SDK at this time.

Thanks!
