§ ¶Hardware overlays in Windows 7 RTM
A while back I wrote about Direct3D9Ex overlays in Windows 7, based on some testing I'd done in Windows 7 RC. Well, I have Windows 7 x64 RTM installed now, so I thought I'd rerun my tests.
Same results. Can't create YUV overlays, LIMITEDRGB flag does nothing, no stretching supported.
Another API broken from the beginning. :(
Is that a limitation of the driver or the API?
I have a similar situation with the ProcAmp support of EVR only working in YUY2 mode, but reporting all's well in YV12 mode without doing anything. Not to mention that when it does work in YUY2 mode, the HUE value is borked.

Hard to say until I actually see the API working properly on some system. The API itself looks fine, but I have no way to tell if the wonkiness Microsoft's or NVIDIA's fault.

Do you want someone to try on ATI hardware? I have at least one Win7 machine with an ATI card.
I tried compiling d3doverlay.cpp from the linked-to post but I think my DX SDK is out-of-date as IID_IDirect3D9ExOverlayExtension is undefined.
Shout if you want it tested on ATI and I'll update my SDK (or throw an exe up if you want).

Unfortunately, the program's not really made for that -- you have to hack it up to test various features. It'd be great to know if the same behavior exists on ATI but I don't want to impose on you.

I'm not familiar with DX coding (I'm more a app developer kinda guy) so it won't be obvious to me what needs changing in the code, but I'd be happy to help run any tests if I can & if it would be useful.
I owe you one for confirming and adding detail to that VS2010 exFAT issue. :)

Just for clarification, the EVR issue is also on an NVIDIA card. NVIDIA has been notorious for neglecting driver-side bugs relating to video support. It took them years (from 90.xx series to 190.xx series and notification of the bug's persistence every time they released a WHQL driver over these years) to fix a bug which prevented a VMR9 window clipping on a monitor's edge.

Microsoft has deprecated DirectShow in favour in the Windows Presentation Foundation technology. This might be related to that. Many DirectX technologies have been deprecated in Windows Vista and 7, which broke backward compatibility.
It's the time again to rewrite stuff.
That's why I don't use WaveRT but converted my project to ASIO. Microsoft is too quick to obsolete their APIs (only the Win32 will last forever).

I think you meant Media Foundation, not Windows Presentation Foundation. Also, D3D9Ex video overlays were added in Windows 7, so it's unlikely that they'd be deprecated already (although it has happened before). Realistically, they're APIs at different levels; Direct3D9 overlays are something you'd use under the hood to implement a DirectShow or MF renderer.
