Runtime crash with latest Vulkan SDK

Hi, just wanted to report this in case you weren't aware, this sample doesn't run anymore due to changes in the Vulkan SDK with respect to Vulkan Video beta version having changed some interfaces / structs.

Thanks

I assume I'm getting the same error on my side:

what would be the plan to get something working and demonstrate that the HW is able to decode a H64 stream ?

Thanks in advance.

Sorry for the issue! A new version of Vulkan Video that we are preparing will also call for an application upgrade. Please keep an eye for updates on drivers and samples during the following two weeks. Please use the driver version that is stated in the README file for the time being.

I gave a try to the driver 515.49.15 suggested here but it's crashing as well. I'm using 515.49.08

Just for the sake of testing, it's possible to apply this patch and the app should decode streams: https://gist.github.com/ceyusa/e6209e2d12d166256ba375bbeb45b310

I gave a try to the driver 515.49.15 suggested here but it's crashing as well. I'm using 515.49.08

Perhaps try the older 470.62.28 driver. I think this is a temporary issue until we get everything updates to the latest API changes.

Sorry, again, for the issue! We have posted a new version of the Vulkan Video decode app and parser that should address all of the above issue against the latest NVIDIA BETA drivers at https://developer.nvidia.com/vulkan-beta-51757-windows and https://developer.nvidia.com/vulkan-beta-5154919-linux. Cheers!

Hello, running the sample I get unresolved external symbols (the functions related to the video api)

Driver Info:

Lib dump: The functions doesn't seem to be present in the lib vulkandumplib.txt

EDIT : I used the DispatchLoaderDynamic to load the function addresses, but I get this error :

I'm using the latest Vulkan SDK version.

Is it related to the driver?
