## What it is
QtAV is a cross-platform multimedia playback framework built on Qt and FFmpeg, providing C++ and QML APIs for building video/audio players with hardware decoding support. It is no longer actively developed; the author recommends its successor mdk-sdk.

## Use cases
- embed video playback in a Qt application
- build a custom media player with C++ or QML
- play video with hardware-accelerated decoding (DXVA2, VAAPI, VideoToolbox, CUDA)
- render subtitles and apply video filters during playback
- play network streams like RTSP and HTTP in a Qt app

## When to choose
- your project is already Qt-based and needs integrated audio/video playback
- you need QML/QtMultimedia-compatible playback APIs
- you need broad hardware decoder support across platforms
- you want an LGPL-licensed playback library

## When to avoid
- you are starting a new project - the author recommends mdk-sdk instead
- you need a framework under active development with new features
- you are not using Qt and just need a standalone media library

## Facets
- artifact type: library
- maturity: maintenance
- function: video-processing, audio-processing, graphics
- domain: media, cross-platform, developer-tools
- platform: cross-platform, cpp
- tags: qt, ffmpeg, multimedia-playback, qml, hardware-decoding, video-player, desktop, mobile
