Aevum is a free, open-source video and audio downloader for Windows and Linux powered by yt-dlp and FFmpeg. It supports YouTube, Vimeo, Twitch, X, Dailymotion, and approximately 1,800 additional websites. Users can preview video titles, thumbnails, durations, and available resolutions before downloading. Video downloads support resolutions up to 4K and output formats including MP4, MKV, and WebM. Audio extraction supports MP3, M4A, Opus, FLAC, and WAV. The application also downloads playlists, selected video segments, thumbnails, and available subtitles. Browser cookie integration enables access to content permitted by signed-in sessions. A download queue displays progress, speed, and remaining time, while bundled dependencies and local processing eliminate mandatory accounts and telemetry.
