This release had been overdue for at least half a year, but due to constant activity in the repository, had to be delayed, and we were finally able to branch off the release recently, before some of the large changes scheduled for 7.0 were merged.

Internally, we have had a number of changes too. The FFT, MDCT, DCT and DST implementation used for codecs and filters has been fully replaced with the faster libavutil/tx (full article about it coming soon).
This also led to a reduction in the the size of the compiled binary, which can be noticeable in small builds.
There was a very large reduction in the total amount of allocations being done on each frame throughout video decoders, reducing overhead.
RISC-V optimizations for many parts of our DSP code have been merged, with mainly the large decoders being left.
There was an effort to improve the correctness of timestamps and frame durations of each packet, increasing the accurracy of variable frame rate video.

Next major release will be version 7.0, scheduled to be released in February. We will attempt to better stick to the new release schedule we announced at the start of this year.

We strongly recommend users, distributors, and system integrators to upgrade unless they use current git master.

Release Notes

 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.
