Crash in nvoglv64.dll when submitting a H.264 Encode Job to the Encode Queue

Crash Message:

Message generated by the Driver:

nvVideoPhysicalDevice::IsGridSdkQualifiedGpu: Not a qualified GRID system. Sessions restrictions may apply.

When I try to submit a H.264 encode task to the encode queue by calling vkQueueSubmit, I get a crash.
The vulkan validation layer doesn’t spit out any messages, and the only message that I get is a message from the Driver.
The driver message “Not a qualified GRID system” is emitted when I create the video session object.
Could it be that my gpu is not supported ?

I added a sample project to this report that replicates the crash.

Hi John5091,
Can you please upgrade to the latest BETA drivers 473.50 (Windows) / 470.62.28 (Linux) and Vulkan API version 1.3.212. Please also have a look at the vk_video_samples/vk_video_encoder at main · nvpro-samples/vk_video_samples · GitHub sample app.
You can find the latest supported Vulkan Video header files at vk_video_samples/common/include at main · nvpro-samples/vk_video_samples · GitHub).

This message is unrelated to your problem - all this message says is that you can’t have more than 3 video-encode sessions created.

Hi tzlatinski1,
Thanks for your response, I was able to find my problem with the vk_video_encode sample project you mentioned.
