Microsoft released AV1 Video Extension (Beta) via their store: Play AV1 videos on your Windows 10 device. This extension is an early beta version of the AV1 software decoder that lets you play videos that have been encoded using the AV1 video coding standard developed by the Alliance for Open Media. Since this is an…
When it comes to vendor specific SDK for hardware assisted video encoding, Intel Media SDK is perhaps the oldest one among current vendors: Intel, NVIDIA, AMD. And also surprisingly the worst one. All three vendors are offering their SDKs for really close capabilities, however the kits are designed and structured differently. If NVIDIA and AMD…
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…
Another example how Microsoft Media Foundation can be annoying in small things. So we have this Video Processor MFT transform which addresses multiple video conversion tasks: The video processor MFT is a Microsoft Media Foundation transform (MFT) that performs colorspace conversion, video resizing, deinterlacing, frame rate conversion, rotation, cropping, spatial left and right view unpacking,…
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…
From AMD AMF SDK documentation, AMF_Video_Encode_API.pdf: The typos are not a big deal for development, even though the symbol with the typo is a shortcut to a string with the same typo: #define AMF_VIDEO_ENCODER_NUM_TEMPORAL_ENHANCMENT_LAYERS L”NumOfTemporalEnhancmentLayers” The SDK offers a good frontend to AMD VCE hardware encoders, however there are a few unfortunate problems: documentation is…
