AMD PowerXpress/Enduro switchable graphics DXGI issue

Yesterday I wrote about the NVIDIA Optimus problem with DXGI where Output Protection Manager API reported Intel certificate for NVIDIA DXGI adapter. AMD hybrid graphics known as “PowerXpress” (and most recently as “Enduro”) exhibits the same behavior: Adapters AMD Radeon HD 8850M Intel(R) HD Graphics Family Adapter: AMD Radeon HD 8850M Vendor Identifier: 0x1002 […]…

MediaFoundationDxgiCapabilities: GPU preference & Hybrid GPU systems

I added a section that enumerates DXGI adapters with the help IDXGIFactory6::EnumAdapterByGpuPreference – this is included into the produced output. Unfortunately the method does not distinguish between dual GPU systems, such as with discrete GPU and additional CPU integrated Intel GPU… DXGI Capabilities NOTE: Baseline capabilities are corresponding to DXGI 1.1 Windowed Stereo: 0 DXGI_FEATURE_PRESENT_ALLOW_TEARING:…

MediaFoundationDxgiCapabilities: with AMF SDK H.264 encoder related data

Yet another post on AMD AMF SDK and hopefully a helpful tool reference. I updated one of the capability discovery applications (MediaFoundationDxgiCapabilities) so that it includes a printout of AMFVideoEncoderVCE_AVC related properties similarly as they are printed for Nvidia video adapters. Information includes: runtime version (and its availability in first place!) maximal resolution, profile and…

Applying Hardsubs to H.264 Video with GPU

Video adapters currently offer a range of services which enables transcoding of H.264 content with certain modifications (including but not limited to flexible overlays, scaling, mirroring, effects and filters) end-to end on GPU keeping data as DirectX Graphics Infrastructure resource at all processing stages. Such specialized processing capabilities are pretty powerful compared to traditional CPU…
