## What it is
A Microsoft open-source library and code sample that integrates FFmpeg into Windows 10/8.1/Phone 8.1 applications via a MediaStreamSource for media playback. It delegates audio/video synchronization and decoding to the Windows media pipeline while using FFmpeg to process a wide variety of media formats.

## Use cases
- play media formats not natively supported by Windows in a UWP app
- use FFmpeg for decoding in a Windows media player
- build a Windows app that streams audio and video with FFmpeg
- integrate FFmpeg with the Windows media pipeline
- leverage built-in Windows decoders for better power efficiency

## When to choose
- you are building a Windows 10/UWP app that needs broad media format support
- you want FFmpeg decoding combined with Windows media pipeline playback and sync
- you want a maintained reference sample for FFmpeg on WinRT

## When to avoid
- you target platforms other than Windows
- you need full control over rendering and synchronization rather than the Windows media pipeline
- you need a cross-platform FFmpeg wrapper

## Facets
- artifact type: library
- maturity: maintenance
- function: video-processing, audio-processing, sdk
- domain: media, windows, developer-tools
- platform: windows, cpp, c
- tags: ffmpeg, mediastreamsource, uwp, winrt, media-playback, code-sample
