// Software Production Line
The previous post was focusing on problems with the hardware MFT decoder provided as a part of video driver package. This time I am going to mention some data about how the inefficiency affects performance of video capture using a high frame rate 260 FPS camera as a test stand. Apparently the effect is better…
Video GPU vendors (AMD, Intel, NVIDIA) ship their hardware with drivers, which in turn provide hardware-assisted decoder for JPEG (also known as MJPG and MJPEG. and Motion JPEG) video in form-factor of a Media Foundation Transform (MFT). JPEG is not included in DirectX Video Acceleration (DXVA) 2.0 specification, however hardware carries implementation for the decoder.…
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 […]…
If you are curious what video encoding capabilities Radeon RX Vega M GH Graphics offers for a Media Foundation application, here are the details. Some introductory information for starters: The AMD Radeon RX Vega M GH is an integrated GPU in the fastest Intel Kaby-Lake-G SoC. It combines a Kaby-Lake processor, a Vega graphics card…
Even though AMD H.264 Video Encoder Media Foundation Transform (MFT) AKA AMDh264Encoder is, generally, a not so bad done piece of software, it still has a few awkward bugs to mention. At this time I am going to show this one: the video encoder transform fails to acquire synchronization on input textures. The problem comes…
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…
I had a wrong assumption that AMD’s H.264 video encoder MFT (and other Media Foundation primitives) are not based on AMF SDK. There were some references to ATI Technologies in the binary (AMDh264Enc64.dll) and most importantly I was unable to change tracing level of the MFT component on runtime. It was a guess that if…
