<p>
A new major release, <a href="http://ffmpeg.org/download.html#release_6.0" target="_blank">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.
This means that releases will be done more often and will be more organized.
</p>
<p>
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 refer 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.

We strongly recommend users, distributors, and system integrators to
upgrade unless they use current git master. </p><p><br></p><p>====</p><p><br></p><p>so .... should we try this or wait for 6.1 "shortly after"?</p></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">чт, 9 февр. 2023 г., 20:43 Andrew Randrianasulu <<a href="mailto:randrianasulu@gmail.com" target="_blank">randrianasulu@gmail.com</a>>:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div><br><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">чт, 9 февр. 2023 г., 20:30 Phyllis Smith <<a href="mailto:phylsmith2017@gmail.com" rel="noreferrer noreferrer noreferrer noreferrer" target="_blank">phylsmith2017@gmail.com</a>>:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-size:small">Nice! hopefully it really will not be until Winter 2023 so I can get all of the GPL headers fixed by then.<br></div></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">some talks suggest it might be in two weeks :-)</div><div dir="auto"><br></div><div dir="auto"><a href="https://people.freedesktop.org/~cbrill/dri-log/index.php?channel=dri-devel&date=2023-02-07" rel="noreferrer noreferrer noreferrer" target="_blank">https://people.freedesktop.org/~cbrill/dri-log/index.php?channel=dri-devel&date=2023-02-07</a><br></div><div dir="auto"><br></div><div dir="auto">====</div><div dir="auto">02:54 Lynne:
