Just a quick hookup of my test Media Foundation media source into new Windows 11 MFCreateVirtualCamera API. Software video source is presented by Windows 11 as a video capture device. Finally, there is a nice way to create virtual cameras, even though Windows 11 (Windows Build 22000) is a minimal requirement. Application produced video stream…
I am replaying a pretty much regular MPEG TS recording taken from air, just with a MPEG TS rollover condition inside. Microsoft Media Foundation – ? FAIL Microsoft Movies & TV Application – ? FAIL (obviously because of #1 above, but let me double this down) Media Player Classic MPC-HC – ? FAIL VLC –…
MFCreateFMPEG4MediaSink (CMPEG4MediaSink class) has no support for H.265/HEVC… MF_E_INVALIDMEDIATYPE… It should have been there. We’re not expecting Dolby AC-4 to be supported [yet], but H.265?
I am sometimes using a rework of earlier DxgiTakeSnapshot application for one specific purpose mentioned below. In addition to Desktop Duplication API, recent version of Windows offer a similar (in sense of acquisition of external video content) API: Windows.Graphics.Capture (hereinafter “WGC”), and the new rework is using this API to capture visual content as a…
There is a new API coming with Windows 11. Finally we will get well defined way to register virtual cameras (perhaps for applications built against Windows Media Foundation API, not DirectShow): MFCreateVirtualCamera. Creates a virtual camera object which can be used by the caller to register, unregister, or remove the virtual camera from the system.…
There is something interesting finally happening with video encoding and also Media Foundation: Intel® Hybrid AV1 Encoder MFT 11 Attributes: MFT_TRANSFORM_CLSID_Attribute: {62C053CE-5357-4794-8C5A-FBEFFEFFB82D} (Type VT_CLSID) MF_TRANSFORM_FLAGS_Attribute: MFT_ENUM_FLAG_HARDWARE MFT_ENUM_HARDWARE_VENDOR_ID_Attribute: VEN_8086 (Type VT_LPWSTR) MFT_ENUM_HARDWARE_URL_Attribute: AA243E5D-2F73-48c7-97F7-F6FA17651651 (Type VT_LPWSTR) MFT_INPUT_TYPES_Attributes: {3231564E-3961-42AE-BA67-FF47CCC13EED}, MFVideoFormat_NV12 MFT_OUTPUT_TYPES_Attributes: MFVideoFormat_AV1 MFT_CODEC_MERIT_Attribute: 7 (Type VT_UI4) MFT_SUPPORT_DYNAMIC_FORMAT_CHANGE: 1 (Type VT_UI4) MF_TRANSFORM_ASYNC: 1 (Type VT_UI4) Intel UHD graphics coming…
More of unusual stuff: mix of Media Foundation pipeline, with a custom media source specifically, with GStreamer pipeline. It appears that with all bulkiness of GStreamer runtime, the framework remains open for integrations and flexible for a mix of pre-built and custom components. PoC push source plugin on top of Media Foundation media session and…
