# Unofficial Windows Media Foundation Samples

Official samples are available [here](https://github.com/microsoft/Windows-classic-samples/tree/master/Samples/Win7Samples/multimedia/mediafoundation) and a brief overview web page [here](https://docs.microsoft.com/en-us/windows/win32/medfound/media-foundation-sdk-samples).

Update Sep 2020: A new official Media Foundation samples repository has been created at [microsoft/media-foundation](https://github.com/microsoft/media-foundation).

A set of minimal sample applications that demonstrate how to use certain parts of Microsoft's Windows Media Foundation API. The original motivation for these samples was an attempt to find a way to stream audio and video from a webcam, encoded as H264 and/or VP8, over RTP and then render at the remote destination. As of January 2020 the MFWebCamRtp sample has been used to stream H264 samples from a webcam source to ffplay.

### Rendering

 - MFAudio - Play audio from file on speaker.
 
 - MFAudioCaptureToSAR - Capture on default audio capture device (microphone) and playback on default audio output device (speaker).
 
 - MFBitmapMftToEVR - Performs a colour conversion on a bitmap byte array and then displays on the Enhanced Video Renderer. 

 - MFBitmapToEVR - Displays a byte array representing a bitmap on the Enhanced Video Renderer.
 
 - MFTopology - Plays audio and video from an mp4 file using the Enhanced Video Renderer and Streaming Audio Renderer.
 
 - MFVideoEVR - Display video from an mp4 file in Window WITHOUT using a topology. Write samples to video renderer directly from buffer.
 
 - MFVideoEVRWebcam - Same as the `MFVideoEVR` sample but replacing the file source with a webcam.
 
 - MFVideoEVRWebcamMFT - Same as the `MFVideoEVRWebcam` sample but manually wires up a color conversion MFT transform instead of setting MF_SOURCE_READER_ENABLE_VIDEO_PROCESSING on the video source reader.  
 
 - WpfMediaUWA - Initial foray into how Media Foundation can work with WPF in a Universal Windows Application (UWA). UWA is currently impractical due to [deployment constraints](https://docs.microsoft.com/en-us/windows/apps/desktop/choose-your-platform), i.e. Windows Store only. Hopefully in 2020 with the introduction of [Windows UI 3.0](https://docs.microsoft.com/en-us/uwp/toolkits/) using the types of controls in this sample will become practical.
 
### Plumbing

 - MFCaptureRawFramesToFile - Captures 100 samples from default webcam to file.

 - MFListTransforms - Lists the available MFT Transforms to convert between two media types.
 
 - MFMP4ToYUVWithMFT - Reads H264 encoded video frames from an mp4 file and decodes them to a YUV pixel format and dumps them to an output file.
 
 - MFMP4ToYUVWithoutMFT - Same as the previous (MFMP4ToYUVWithMFT) sample but WITHOUT having to wire up the H264 decoder. Reads H264 encoded video frames from an mp4 file and decodes them to a YUV pixel format and dumps them to an output file.
 
 - MFSampleGrabber - Copy of the Sample Grabber Sink example from https://docs.microsoft.com/en-us/windows/win32/medfound/using-the-sample-grabber-sink but grabbing both audio and video samples from an mp4 file rather than solely audio samples.

 - MFWebCamToFile - Captures 100 samples from default webcam to an mp4 file.
 
### Webcam -> H264 -> RTP

 - MFH264RoundTrip - Captures video frames, H264 encode to byte array, decode to YUV (replicates encode, transmit, decode).

 - MFWebCamRtp - Stream webcam video over RTP to ffplay.
  
 - MFWebCamToH264Buffer - Captures the video stream from a webcam to an H264 byte array by directly using the MFT H264 Encoder.

### Webcam -> H264/VP8 -> WebRTC -> Web Browser
 
 - MFWebCamWebRTC - Stream VP8 encoded webcam video to a WebRTC client (only works with Chrome).
 
 - MFWebCamWebRTCH264 - **Not Working** Stream H264 encoded webcam video to a WebRTC client.
