As seen on reddit, the Alliance for Open Media - AOM has released
SVT-AV1 v. 2.3.0<br>
The Scalable Video Technology for AV1 (SVT-AV1 Encoder) is an
AV1-compliant software encoder library. <br>
<br>
<ul>
<li>
<p> NEW FAST DECODE MODE </p>
</li>
<li>
<p> New fast-decode (2) to allow for an average AV1 software
cycle reduction of 25-50% vs fast-decode 0 with a 1-3% BD-Rate
loss across the presets </p>
</li>
<li>
<p> Improved fast-decode (1) option to increase its AV1 software
cycle reduction by ~10% while maintaining the same quality
levels </p>
</li>
<li>
<p> Improved --lp settings for high resolutions, with CRF
gaining a ~4% improvement in speed and VBR gaining ~15% </p>
</li>
<li>
<p> Further Arm-based optimizations improving the efficiency of
previously written Arm-neon implementations by an average of
30% </p>
</li>
<li>
<p> Address speed regressions for high resolutions first pass
encode by tuning the threading parameters, with 1080p showing
the biggest gains </p>
</li>
<li>
<p> Enabled AVX512 by default in cmake allowing for ~2-4%
speedup</p></li></ul></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">I hope system-wide nasm installed on Phyllis's build systems will cope with that .....</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><ul><li><p> </p>
