Ping, release has been tagged for quite a while now.
Final version:
A new major release, <a href="download.html#release_6.0">FFmpeg 6.0 "Von
Neumann"</a>,
is now available for download. This release has many new encoders and
decoders, filters,
ffmpeg CLI tool improvements, and also, changes the way releases are done.
All major
releases will now bump the version of the ABI. We plan to have a new major
release each
year. Another release-specific change is that deprecated APIs will be
removed after 3
releases, upon the next major bump. The last minor release of a major
version will be an
LTS release.
This means that releases will be done more often and will be more organized.
New decoders featured are Bonk, RKA, Radiance, SC-4, APAC, VQC, WavArc and
a few ADPCM formats.
QSV and NVenc now support AV1 encoding. The FFmpeg CLI (we usually reffer
to it as ffmpeg.c
to avoid confusion) has speed-up improvements due to threading, as well as
statistics options,
and the ability to pass option values for filters from a file. There are
quite a few new audio
and video filters, such as adrc, showcwt, backgroundkey and ssim360, with a
few hardware ones too.
Finally, the release features many behind-the-scenes changes, including a
new FFT and MDCT
implementation used in codecs (expect a blog post about this soon),
numerous bugfixes, better
ICC profile handling and colorspace signalling improvement, introduction of
a number of RISC-V
vector and scalar assembly optimized routines, and a few new improved APIs,
which can be viewed
in the doc/APIchanges file in our tree.
A few submitted features, such as the Vulkan improvements and more FFT
optimizations will be in the
next minor release, 6.1, which we plan to release soon, in line with our
new release schedule.
Some highlights are:
