## What it is
LAV Filters is a set of open-source DirectShow filters based on FFmpeg's libavformat and libavcodec, providing media splitting and audio/video decoding for Windows. It enables DirectShow-based players to play virtually any media format, including MKV, MP4, TS, FLV, and BluRay structures.

## Use cases
- play any video format in a DirectShow player like MPC-HC
- decode audio and video with ffmpeg-based DirectShow filters
- configure preferred audio and subtitle language selection
- replace Haali Media Splitter as the system splitter
- enable BluRay playlist playback in DirectShow players

## When to choose
- you use a DirectShow-based media player on Windows and need broad format support
- you want ffmpeg-quality decoding integrated into DirectShow graph playback
- you need configurable audio/subtitle stream selection by language

## When to avoid
- you need a standalone media player rather than DirectShow filters
- you develop on non-Windows platforms, as DirectShow is Windows-only
- you need a media framework for embedding playback in your own app rather than system-wide filters

## Facets
- artifact type: library
- maturity: active
- function: video-processing, audio-processing, graphics
- domain: media, desktop-applications, windows
- platform: windows, cpp
- tags: directshow, ffmpeg, media-playback, codecs, splitter, decoders
