April 5th, 2024, FFmpeg 7.0 "Dijkstra"

A new major release, FFmpeg 7.0 "Dijkstra", is now available for download. The most noteworthy changes for most users are a native VVC decoder (currently experimental, until more fuzzing is done), IAMF support, or a multi-threaded ffmpeg CLI tool.

This release is not backwards compatible, removing APIs deprecated before 6.0. The biggest change for most library callers will be the removal of the old bitmask-based channel layout API, replaced by the AVChannelLayout API allowing such features as custom channel ordering, or Ambisonics. Certain deprecated ffmpeg CLI options were also removed, and a C11-compliant compiler is now required to build the code.

As usual, there is also a number of new supported formats and codecs, new filters, APIs, and countless smaller features and bugfixes. Compared to 6.1, the git repository contains almost ∼2000 new commits by ∼100 authors, touching >100000 lines in ∼2000 files — thanks to everyone who contributed. See the Changelog, APIchanges, and the git log for more comprehensive lists of changes.

January 3rd, 2024, native VVC decoder

The libavcodec library now contains a native VVC (Versatile Video Coding) decoder, supporting a large subset of the codec's features. Further optimizations and support for more features are coming soon. The code was written by Nuo Mi, Xu Mu, Frank Plowman, Shaun Loo, and Wu Jianhua.

The libavformat library can now read and write IAMF (Immersive Audio) files. The ffmpeg CLI tool can configure IAMF structure with the new -stream_group option. IAMF support was written by James Almer.

December 12th, 2023, multi-threaded `ffmpeg` CLI tool

Thanks to a major refactoring of the ffmpeg command-line tool, all the major components of the transcoding pipeline (demuxers, decoders, filters, encodes, muxers) now run in parallel. This should improve throughput and CPU utilization, decrease latency, and open the way to other exciting new features.

Note that you should not expect significant performance improvements in cases where almost all computational time is spent in a single component (typically video encoding).
