am wondering if the news and enhancements of importance to
<br>
CinGG/FFmpeg 6.1 users may be outlined, including what is
ready now and <br>
expected upcoming next?<br>
<br>
Something listed last month by Andrew in "ffmpeg 6.1 is
out!" and by <br>
Phyllis in "GIT... CinGG changes >.FFmpeg 6.1 upgrade
from 5.1. ."<br>
as the News November 10th, 2023, FFmpeg 6.1 "Heaviside"<br>

For example while the AV1 codec was mentioned available
for CinGG <br>
already in February News 2019<br>

<br>
AV1 looks to be an even more important improvement with
FFmpeg 6.0 and <br>
6.1, according to some selected articles below:<br>

<div dir="auto">for this part you need hardware de/encoding
support in GPU - so recent AMD or Intel. recent libva. For AMD
also new mesa, most likely. Quite a lot of moving pieces ..
someone tested at least ffmpeg's vaapi support on Intel, but
because (from my reading of code) we do not do hw decoding in
10bit ... results might be less rosy than by using ffmpeg
directly.</div>

I don't know the AV1 hw limits, but it will be of interest to try
this codec with FFmpeg (next year)<br>
<a class="moz-txt-link-freetext" href="https://trac.ffmpeg.org/wiki/Encode/AV1">https://trac.ffmpeg.org/wiki/Encode/AV1</a><br>
<br>
So far I just verified that the current prebuild FFmpeg 6.0.1
(packman repo) on Tumbleweed-Slowroll has AV1 Encoder support:<br>
<blockquote>ffmpeg -codecs -hide_banner | grep av1<br>
DEV.L. av1 Alliance for Open Media AV1
(decoders: libdav1d libaom-av1 av1 av1_cuvid av1_qsv ) (encoders:
libaom-av1 librav1e libsvtav1 av1_nvenc av1_amf )<br>
