Play an MP3 with Media Foundation

An under 100 lines of C++ code sample that plays an MP3 file with Microsoft Media Foundation.

https://github.com/roman380/MediaFoundationMinimalAudioPlayback

Comes from this StackOverflow question, however unlike Microsoft’s sample it does not spread simple code among multiple source code files, gives a quick way to build & run, shows modern C++ practices (including Microsoft Windows Implementation Library in wil branch – the library I recommend to use).

The sample quickly goes over main concepts: topology, nodes, session, events, asynchronous processing. Media Foundation’s “Intelligent Connect” automatically & transparently supplying two Media Foundation Transforms to decode MP3 audio and to fit audio format to acceptable by audio playback device.
