ms-media-foundation

I'm writing a simple multimedia application in Visual Studio 2013 and I need to enumerate camera devices connected to my computer and create a media source object to link to one of them. I use Media Foundation SDK and tried to run the guide here: https://msdn.microsoft.com/en-us/library/windows/desktop/dd940326(v=vs.85).aspx : #include <Mfapi.h> #include <mfidl.h> #include <mfobjects.h> #include <iostream> #pragma comment(lib, "Mfplat") #pragma comment(lib, "Mf") template <class T> void SafeRelease(T **ppT) { if (*ppT) { (*ppT)->Release(); *ppT = NULL; } } HRESULT CreateVideoDeviceSource

I am able to extract samples out of a video using the readSample method. Now how can I play the data present in those samples? Or how to play IMFSample ? Sample IMFSample is a block of data, such as video frame or a chunk of audio sequence. This is a tiny piece of data to be played alone. The API addresses more sophisticated playback scenarios, such as where playback is a session where one or more streams are streamed in sync. Be sure to check Getting Started with MFPlay on MSDN to see how playback is set up with Media Foundation. 来源： https://stackoverflow.com/questions/9719338/how-to-play

I am able successfully to encode the data by H264 using Media Foundation Transform (MFT) but unfortunately I got a very high CPU(when I comment in the program the calling of this function I got low CPU).It is few steps followed to get the encoding so I can't do anything to improve it?Any idea can help HRESULT MFTransform::EncodeSample(IMFSample *videosample, LONGLONG llVideoTimeStamp, MFT_OUTPUT_STREAM_INFO &StreamInfo, MFT_OUTPUT_DATA_BUFFER &encDataBuffer) { HRESULT hr; LONGLONG llSampleDuration; DWORD mftEncFlags, processOutputStatus; //used to set the output sample IMFSample

I'm writing a tool in C# that muxes H.264 frames into MP4 files, and I'm using Media Foundation's media sink with sink writer to do this. Things work pretty well under Win8, but under Windows 7 the same code throws an exception, HResult: 0xC00D36E6 (MF_E_ATTRIBUTENOTFOUND), when invoking sink writer's Finalize method. As a result, the generated MP4 file is not properly closed, and is (of course) not playable. The mftrace log shows that the failure under Windows 7 occurs somewhere after (or during) the internal call to IMFSinkWriter::PlaceMarker. Under Windows 8 the corresponding line in the

I'm a newbie to native development on Windows, but I've been tasked with creating a small app that will list out all the transformers for various video+audio codecs. Looking at the MSDN documentation, there doesn't seem to be much direct documentation on doing this. Docs that I've found indicate that this information is stored in the registry (not sure where) so that could be a vector. Is this possible? Generally how should I do it? Thanks EDIT: It does seem that a call to MFTEnumEx with the parameters of type MFT_REGISTER_TYPE_INFO set to NULL returns a count of 8 MFTEnumEx(MFT_CATEGORY_VIDEO

My Windows MFC application has a function to export a video file. And it can select encoding format (via WMV or MP4 ) and frame size. But, Unfortunately when i tried to export MP4 file which is set large frame size, everytime MF_E_INVALIDMEDIATYPE happened. Simply put, here is the result when i tested in each case. WMV 640 x 480 ... OK 640 x 576 ... OK 1280 x 720 ... OK 1280 x 720 ... OK 1920 x 1080 ... OK 2048 x 1556 ... OK 4096 x 2160 ... OK MP4 640 x 480 ... OK 640 x 576 ... OK 1280 x 720 ...
