In their own words
FFmpeg
FFmpeg is free, open-source software for recording, converting, and streaming audio and video on Windows, macOS, and Linux. Its command-line tool converts media files between formats, supports local recording, and lists AVI among its output formats. Output protocols include HLS, RTMP, RTMPS, RTP, RTSP, SRT, and UDP. Hardware acceleration is available for encoding and decoding. Decoding support includes Vulkan, VAAPI, and OpenHarmony, and Vulkan codecs can work on implementations of Vulkan 1.3. The Vulkan compute approach supports FFv1 encoding and decoding and ProRes RAW decoding, but only for codecs designed for parallel decoding. FFmpeg’s transcoding components run in parallel, which can improve throughput and CPU use; gains may be limited when one component dominates the processing. The project accepts contributions through its Forgejo instance and offers mailing lists, IRC, forums, bug reports, a wiki, and conferences. Version 8.1 Hoare was announced as available for download on March 16, 2026.
