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…
For already years Nvidia’s H.264 video encoder Media Foundation Transform has been broken giving REGDB_E_CLASSNOTREG “Class not registered” failure in certain circumstances, like main display is not the one connected to Nvidia video adapter. As simple as this: CoInitialize(NULL); MFStartup(MF_VERSION); class __declspec(uuid(“{60F44560-5A20-4857-BFEF-D29773CB8040}”)) CFoo; // NVIDIA H.264 Encoder MFT CComPtr<IMFTransform> pTransform; const HRESULT nCoCreateInstanceResult = pTransform.CoCreateInstance(__uuidof(CFoo));…
If I recall correctly, Intel was the first vendor to supply H.264 hardware video encoder as a Media Foundation Transform (since Windows 7) and overall Intel Quick Sync Video (QSV) was the earliest widely available implementation of hardware assisted encoding. However one of the aspects of such encoding seems to be missing: update of encoder…
I wrote a few posts on hardware H.264 encoding (e.g. this and the latest one Applying Hardsubs to H.264 Video with GPU). A blog reader asked a question regarding availability of the mentioned Intel Quick Sync Video support with low end Intel x5-Z8300 CPU. […] Intel has advertised that the Cherry Trail CPUs support H264…
Some recent update in Media Foundation platform introduced a new bug related to fragmented MP4 files and H.264 video. The bug shows up consistently with file versions: mfplat.dll – 10.0.14393.351 (rs1_release_inmarket.161014-1755)Â Â Â 15-Oct-16 05:48 mfmp4srcsnk.dll – 10.0.14393.351 (rs1_release_inmarket.161014-1755)Â Â Â 15-Oct-16 05:45 The nature of the problem is that MPEG-4 File Source is incorrectly time stamping the data:…
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…
