Capture failed: Preview image conversion failed

Intel GPA is quite impressive, one of the best tools I've recently found :)

Unfortunately, I'm unable to capture a frame in my own DirectX 11 application (for testing reasons I deleted all code except the DirectX Initialization and Present). It always fails with the message "Preview image conversion failed" and the following log:

[00002d04] 16:52:46:641 |    INFO |     INTERCEPTOR | InterceptorDll.cpp:68    | GPA shim DLL attached.

I tried it in other applicatiosn and there it works perfectly, such as World of Warcraft oder Starcraft 2. When I use DirectX 9 in my Application it works too. Under DirectX 11 the HUD is even showing and I can see the graphs running and use the debug option. Only the frame capture doesn't work.

Do you have any directions for me?

Thanks in advance!

Hi Tobias,

Sorry for the late response!

I have a couple workarounds you can try for frame capturing:

Try disabling "tracing" and trying a frame capture again. Graphics monitor -> Profiles -> Tracing -> Disable Tracing
Try to inject with "auto-detect launched application". Graphics monitor -> Preference -> auto-detect launched applicatio

Also, If you could post your about dialog here so I can see what driver version and version of GPA you are using, that would be great.

If these workarounds do not work for you, we might need to get a copy of your application so we can reproduce the issue here.

Cheers!

Seth

Hi Seth,

Hi Seth,

I finally got it working today, while I was assembling the files to upload for you. The reason was a unused import of the DirectX 9 headers, which statically linked the DLLs into the application. I have no idea why this prevented the Graphics Monitor from capturing, but now with lazy loading everything works fine! It's curious that if I used DirectX 9 for rendering it worked, but with DirectX 11 and loaded DirectX 9 not.

If you want to track down this issue nevertheless, I've added all information you requested:

The workarounds didn't worked for me, nothing happened.

Great! Glad to hear that

Great! Glad to hear that everything is working now!

I have a couple ideas of why this could have failed. I'l grab your apps and I'll see if we can get a fix in for this.

Anyway, i'm glad you are unblocked. :)

Cheers,

Seth
