FFmpeg Batch AV Converter is a graphical interface for using FFmpeg's command-line capabilities in audio and video workflows. It supports unlimited single-file or multi-file batch encoding for formats handled by FFmpeg, including MP3, AAC, AC3, FLAC, WAV, Opus, and Vorbis. Encoding options include simultaneous jobs, two-pass processing, fixed output target size, and custom parameters that can be created with an encoding wizard. Users can drag and drop files, track progress, change priority, pause or resume, and set automatic shutdown or folder monitoring. The application also supports stream mapping, multiplexing, demuxing, subtitle processing, trimming, concatenation, thumbnail extraction, image-to-video creation, silence detection, splitting, and chapter creation. It can batch-download YouTube videos, live events, and m3u8 links through a youtube-dl/yt-dlp interface for supported URLs. The free, open-source project has been developed since 2017 under LGPL-2.1. Windows and Linux are supported; Linux use requires Wine 9.0 or higher and wine-mono.
