Cannot use ProcessedImage Resource with CUDA

I'm trying to merge the "ProcessClipCUDA" and "ExtractFrame" samples in the Blackmagic RAW SDK to test working with image data processed via CUDA. But I'm getting segfaults any time I try and access the ProcessedImage's actual data retrieved with GetResource. I've tried a few different things and using the GetResource method I can see that it does have data, but attempting to access it always causes a segfault.

Code: Select all

Thread 7 "ExtractFrameCUD" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fffe4ffd700 (LWP 194755)]
0x0000555555556712 in OutputImage (width=4608, height=2592, imageData=0x7fffac000000) at ExtractFrameCUDA.cpp:114
114                             unsigned char red = rgba[0];


I've attached a bare minimum version of the combined example projects that has the issue.

Am I missing something with how to access the data?


I did have to modify the CUDART_VERSION check to look for "10010" instead of "10000" but I'm not getting any other errors so I don't believe that is the cause but I figured I should mention it.

Hi, it actually looks like there's some issues with our CUDA sample as it actually assumes a CPU pipeline. We will try correct this soon and I will post an updated sample here in this thread at a later stage. Thanks!

It felt like I was missing something big so that explains it. Thanks for letting me know and I look forward to the updates!
