on windows 7 the windows media player supports .ts files very well, in the sense that windows media player knows how to handle such files without any additional codec packs. however if I try to use graphedit to "render" a .ts file, it complains it doesnt know how to build a graph for it. what method does windows media player use to demux/decode these files? is it directshow? windows media foundation? BDA? Microsoft TV Technologies? unified tuning model? whatever the method they use, is available as an API to be used in my custom application? In DirectShow using only Microsoft filters it can be

I want to get a list of all FPS values that my webcam supports. In How to Set the Video Capture Frame Rate msdn article it says that I can query the system for maximum and minimum supported FPS of a particular camera. It also says: The device might support other frame rates within this range. And in MF_MT_FRAME_RATE_RANGE_MIN it says: The device is not guaranteed to support every increment within this range. So it sounds like there is no way to get all of the supported FPS values by the camera in Media Foundation, just the max and min. I know that on Linux v4l2-ctl --list-formats-ext command

I'm trying to encode the ID3D11Texture2D to mp4 using MediaFoundation. Below is my current code. Initializing Sink Writer private int InitializeSinkWriter(String outputFile, int videoWidth, int videoHeight) { IMFMediaType mediaTypeIn = null; IMFMediaType mediaTypeOut = null; IMFAttributes attributes = null; int hr = 0; if (Succeeded(hr)) hr = (int)MFExtern.MFCreateAttributes(out attributes, 1); if (Succeeded(hr)) hr = (int)attributes.SetUINT32(MFAttributesClsid.MF_READWRITE_ENABLE_HARDWARE_TRANSFORMS, 1); if (Succeeded(hr)) hr = (int)attributes.SetUINT32(MFAttributesClsid.MF_LOW_LATENCY, 1); /

I'm writing this library that implements some basic audio player features in C++/CLI via the Media Foundation framework that will be consumed by managed code. I can play audio, stop, pause, etc just fine. For anyone who is not familiar with Media Foundation, the media session posts events that you can handle for notifications. This is done by calling BeginGetEvent on the session object with an IMFAsyncCallback object. The IMFAsyncCallback defines the method Invoke(IMFAsyncResult) that you should implement to handle the events. When an event occurs, the invoke method is called by the session

I need some way to get screen data and pass them to DX9 surface/texture in my aplication and render it at at least 25fps at 1600*900 resolution, 30 would be better. I tried BitBliting but even after that I am at 20fps and after loading data into texture and rendering it I am at 11fps which is far behind what I need. GetFrontBufferData is out of question. Here is something about using Windows Media API , but I am not familiar with it. Sample is saving data right into file, maybe it can be set up to give you individual frames, but I haven't found good enough documentation to try it on my own. My

I'm using the windows media foundation api to enumerate both my microphones and available cameras, which both work. Here is my enumeration code: class deviceInput { public: deviceInput( REFGUID source ); ~deviceInput(); int listDevices(bool refresh = false); IMFActivate *getDevice(unsigned int deviceId); const WCHAR *getDeviceName(unsigned int deviceId); private: void Clear(); HRESULT EnumerateDevices(); UINT32 m_count; IMFActivate **m_devices; REFGUID m_source; }; deviceInput::deviceInput( REFGUID source ) : m_devices( NULL ) , m_count( 0 ) , m_source( source ) { } deviceInput::~deviceInput()
