An under 100 lines of C++ code sample that plays an MP3 file with Microsoft Media Foundation. https://github.com/roman380/MediaFoundationMinimalAudioPlayback Comes from this StackOverflow question, however unlike Microsoft’s sample it does not spread simple code among multiple source code files, gives a quick way to build & run, shows modern C++ practices (including Microsoft Windows Implementation Library…
NVIDIA consumer grade hardware provides support nowadays for – mostly – three concurrent sessions. The support matrix is provided here: Video Encode and Decode GPU Support Matrix | NVIDIA Developer. This small tool starts video encoding with given signal parameters (resolution, rate) and provides an easy way to measure load of GPU video encoding engine.…
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.…
