## What it is
RxFFmpeg is an Android framework built on FFmpeg 4.0 (with X264, mp3lame, fdk-aac, opencore-amr, and OpenSSL) for fast audio and video editing and processing. It supports running arbitrary FFmpeg commands with progress callbacks, interruption, sync/async execution, hardware acceleration via MediaCodec, and features like video concatenation, transcoding, compression, trimming, stickers, subtitles, filters, and playback.

## Use cases
- compress videos on android
- trim and cut video clips in an android app
- add subtitles or watermarks to video
- extract audio from video
- run ffmpeg commands on android
- convert images into a video slideshow
- reverse or speed up video playback
- build a video editor app for android

## When to choose
- you need FFmpeg-powered video/audio editing on Android with a packaged single .so library
- you want hardware-accelerated encoding via MediaCodec with x264 compression
- you need progress callbacks and command interruption for media processing tasks

## When to avoid
- you target platforms other than Android
- you need the latest FFmpeg version or active development (last release 2023, FFmpeg 4.0 is dated)
- you require a permissively licensed dependency and cannot accept the missing license file

## Facets
- artifact type: library
- maturity: maintenance
- function: video-processing, audio-processing, image-processing
- domain: mobile-development, media
- platform: cpp, c
- tags: ffmpeg, video-editing, video-compression, transcoding, jni, media-player, x264, openssl, video, audio, android
