[Bug]: AMF_VIDEO_ENCODER_RECONSTRUCTED_PICTURE returns AMF_NOT_FOUND on RX 7900 XTX Ubuntu 22.04

[RFCArrow]

Describe the bug data->GetProperty(AMF_VIDEO_ENCODER_RECONSTRUCTED_PICTURE, &recon) always returns AMF_NOT_FOUND. I initially found this issue in my own code, but discovered this can also be observed by building and running the SimpleFrameInjection sample project and checking the return value using a debugger. The docs suggest that this should be supported on the RX 7900 XTX.

"This feature is supported by Radeon RX 5000 Series or newer GPUs"

To Reproduce cd AMF/amf VK_SDK_PATH=~/vulkan/1.3.239.0 make -C public/samples ./bin/dbg_64/SimpleFrameInjection

Setup (please complete the following information): OS: Ubuntu Linux 22.04 LTS (5.19.0-45-generic) GPU: RX 7900 XTX Driver Version:

amdgpu         1:5.4.50406-1580598.22.04 amd64        Meta package to install amdgpu components.
libamdenc-amdgpu-pro:amd64 1.0-1580631.22.04 amd64        AMD Encode Core Library
amf-amdgpu-pro:amd64 1.4.29-1580631.22.04 amd64        AMDGPU Pro Advanced Multimedia Framework

AMF Source: 1.4.29 origin/master (bd5db31) Which component has the issue: Encoder

Debug Log (please upload or paste):

Expected behavior GetProperty returns AMF_OK and the reconstructed picture is available for use.

Additional context Other sample projects function correctly including SimpleEncoder and SimpleDecoder.

Thank you for catching this. The current public driver does not have support for this feature in Vulkan. The support will be available in the next public driver release.

Please stay tuned 😃

[RFCArrow]

Thanks for the update @rhutsAMD, that's great! Is there a similar limitation with support for B-frames using Vulkan? I've noticed that I haven't been able to generate any so far. Happy to put more details in another issue if it helps.

[rhutsAMD]

B-frame support for Vulkan should already be present in the latest public driver.

Could you please provide the following information on how you are trying to generate B-frames?

• Full command line args used
• Any modifications to the sample code
• Debug log
• Driver version

[RFCArrow]

Sorry for the slow response, I've been quite busy. I'll try and get these bits together soon

[RFCArrow]

Thanks for your patience. To avoid mixing things up, I've opened https://github.com/GPUOpen-LibrariesAndSDKs/AMF/issues/403 with the information requested above

[rhutsAMD]

Closing as the issue has been resolved in #403.
