32-bit USB Webcam Driver Issue

Hello,

My USB webcam is recognized when I build my app for Win32, but it fails to be detected under Win64. I believe this is due to the webcam relying on a 32-bit driver.

How can I ensure my application supports both 32-bit and 64-bit webcam drivers? :?:
Any advice or solutions would be greatly appreciated.

I'm using:
VCL
Delphi 13.1 Pro
RVMedia 12.0

RVMedia relies on DirectX when working with local cameras.
I suppose that 32bit applications can work only 32bit drivers, and 64bit only with 64bit.
But I think that almost 100% cameras have both

My old USB webcam is only detected on Win32. My new laptop cam is detected both Win32 and Win64. I think building for Win32 is the safest choice now.
