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…

New platform, Universal Windows Platform (UWP), offers new Media Foundation bugs. UWP Media Element embeds a Media Foundation video renderer to present media video frames played back. Under certain conditions, the Media Element control fails to present video inline with just incrementing the presentation time indicating playback in progress. Nevertheless once expanded full screen the…
Not the first, not the last. A Direct3D 11 enabled Media Foundation transfer fails to transfer sample attributes while doing the conversion. Why attributes are important in first place? Because we can associate data with samples/frames and have them passed through attached to specific frame as the conversion goes and as the data transits through…
Media Foundation version of Reference Signal Source is UWP friendly. It can be played using stock MediaElement control (whether it is a C# or JS project), is also Direct3D aware and friendly and as such integrates well with the MediaElement. Then on top of that the whole bundle is even WACK friendly and is ready…
This is basically a cross-post of StackOverflow answer: How do I encode raw 48khz/32bits PCM to FLAC using Microsoft Media Foundation? So, Microsoft introduced a FLAC Media Foundation Transform (MFT) Encoder CLSID_CMSFLACEncMFT in Windows 10, but the codec remains undocumented at the moment. Supported Media Formats in Media Foundation is similarly out of date and…
