Just a small tool here to try a few of a popular resolutions and measure video encoding latency. The encoder is running in configuration to address needs of real-time encoding with speed over quality setup. Note that the performance might be affected by side load, such as graphics application (I often use this application for…
A few weeks ago I posted a problem with AMF SDK about a property included into enumeration and triggering a failure in a followup request for value. It appeared to be “internal property” to intentionally tease the caller and report error by design, unlike all other dozens of SDK properties. And of course to raise…
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…
