MediaFoundationMinimalAudioPlayback

See original StackOverflow question.

The application plays an MP3 file (you should supply yours) in less than 100 lines of C++ code with Microsoft Media Foundation.

See wil branch with a bit more of code, and the code that produces printout below.

Note that we are supplying MP3 file media source (node 0) and default audio output renderer (AKA sink, output; node 1). Microsoft Media Foundation resolves topology and supplies two transforms in order to connect source to sink:

1. MF_TOPONODE_DECODER CLSID_MP3DecMediaObject to decode MP3 audio
2. CLSID_AudioResamplerMediaObject to fit audio format to what device is capable to play
