I am looking for to start a thread at a specified time with Media Foundation. I know that in DirectShow there is a function called by IMediaFilter where tStart is the time value of the reference clock.: Interface::HRESULT Run(REFERENCE_TIME tStart); But in Media Foundation there is no such function that will run or start a thread with a time as a parameter. Is there a solution to do this in Media Foundation? Neither DirectShow or Media Foundation have functionality that matches the question description. Both APIs have methods to start activity immediately following the request. DirectShow's

This is going to be my first question in StackOverflow after several days looking for an explanation. Please, be gentle with me for asking because I know my problem is a bit bizarre to be a general problem. I made a MF capture video application, based in the Microsoft example 'CaptureToFile'. It did work on Windows 7 x64. I upgraded to Visual Studio 2013 without problems. Problems arose when I try to put all the development on a Windows 8.1 x64 machine. The app compiles and executes without error, but it's UNABLE to capture samples by using m_pReader->ReadSample() in asynchronous mode; only

I am using Media Foundation to play videos. On windows 7 some videos encoded with Mpeg1/Mpeg2 PS and Windows Media Player can play them, but Media Foundation does not(I tried to register a stub MPEG1Source but it still does not work). I noticed some of these files could be played with directshow but not Media foundation(can not be open at all). I guess "media player" does not use Media Foundation only? Is it possible to use Media Foundation to play these file? If it is not, how does Media player work? Thanks a lot. P.S. I have read the windows SDK and I registered a "fake" mpeg1 decode and it

I'm attempting to stream a H.264 video feed to a web browser. Media Foundation is used for encoding a fragmented MPEG4 stream ( MFCreateFMPEG4MediaSink with MFTranscodeContainerType_FMPEG4 , MF_LOW_LATENCY and MF_READWRITE_ENABLE_HARDWARE_TRANSFORMS enabled). The stream is then connected to a web server through IMFByteStream . Streaming of the H.264 video works fine when it's being consumed by a <video src=".."/> tag. However, the resulting latency is ~2sec, which is too much for the application in question. My suspicion is that client-side buffering causes most of the latency. Therefore, I'm

I'm trying to use Color Converter DMO ( http://msdn.microsoft.com/en-us/library/windows/desktop/ff819079(v=vs.85).aspx ) to convert RBG24 to YV12/NV12 via Media Foundation. I've created an instance of Color Converter DSP via CLSID_CColorConvertDMO and then tried to set the needed input/output types, but the calls always return E_INVALIDARG even when using media types that are returned by GetOutputAvailableType and GetInputAvailableType . If I set the media type to NULL then i get the error that the media type is invalid, that makes sense. I've seen examples from MSDN, where people do the same

I'm trying to decode an mp4 video using Windows Media Foundation classes and converting frames in to 2D textures that can be used by a DirectX shader for rendering. I've been able to read the source stream using MFCreateSourceReaderfromURL and been able to read the media type of the stream which has its major type MFMEdiaType_Video and minor type as MFVideoFormat_H264 as expected. I'm now needing to convert this format in to an RGB format that could be used to initialise a D3D11_TEXTURE2D resource and resource view which can then be passed to a HLSL pixel shader for sampling. I've tired using

I am porting my Direct Show camera based SDK to MFT. In my old code I have KSProxy interface like IksTopolgy,IKsControl and IKsProperty . IksTopolgy,IKsControl is used to enumerate the property set and IKsProperty to get/set the property value. Now I was trying to same in new code.I am able to enumerate the property i.e following code is supported in MFT. CComPtr<IKsTopologyInfo> ksTopology = NULL; hRet = m_pMediaSource->QueryInterface(&ksTopology); But IKsProperty interface which is used to get/set the property value is not working returning E_NOINTERFACE. hRet = m_pMediaSource-

I have an issue when finalizing a video recording into an .mp4 using Media Foundation where the call to IMFSinkWriter->Finalize(); hangs forever. It doesn't always happen, and can happen on almost any machine (seen on Windows server, 7, 8, 10). Flush() is called on the audio and video streams before hand and no new samples are added between Flush and Finalize . Any ideas on what could cause Finalize to hang forever? Things I've tried: Logging all HRESULT s to check for any issues (was already checking them before proceeding to the next line of code) Everything comes back as S_OK , not seeing
