**Description**  
I am integrating the Video-SDK to my app.

Now, I need to manipulate the camera frames in order to implement the software zoom functionality. Once this is done, if I’m not mistaken, I should use externalVideoSource.

I’ve been using your example application, but the RAW VIDEO example doesn’t seem to work. I have done several tests:

1.Use the VirtualVideoSource as is  
2. Uncomment what is inside onInitialize in VirtualVideoSource

In the log I see that it executes sender.sendVideoFrame but I don’t receive it on the second device.

I WOULD LIKE TO

1. If you could provide me with a snippet/sample code/example that shows how to use RAW VIDEO

2. Confirm if my idea of how to implement Zoom by software is correct.

**Which Android Video SDK version?**  
v1.2.1 (1016)

Hi @deneb.chorny,

For information on how to utilize raw data, please see our [raw data documentation](https://marketplace.zoom.us/docs/sdk/video/android/advanced/raw-data). If you run into any specific issues when implementing this feature, let me know and I’ll be happy to help.

Thanks!
