<div dir="ltr"><div class="gmail_default" style="font-size:small">Updated X265 library to version 4.0 was checked into GIT. It deserves more generic testing but I have encoded at least 4 files and decoded at least 3 by loading and playing. Thanks to Andrew, a patch to ffmpeg 7.0 was added to update x265 into a working set.<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Sep 26, 2024 at 2:58 AM Andrew Randrianasulu via Cin <<a href="mailto:cin@lists.cinelerra-gg.org">cin@lists.cinelerra-gg.org</a>> wrote:<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"><a href="https://bitbucket.org/multicoreware/x265_git/commits/6318f223684118a2c71f67f3f4633a9e35046b00" rel="noreferrer" target="_blank">https://bitbucket.org/multicoreware/x265_git/commits/6318f223684118a2c71f67f3f4633a9e35046b00</a><div dir="auto"><br></div><div dir="auto">======</div><div dir="auto"><br></div><div dir="auto"><div dir="auto"><div><pre>Version 4.0

</pre></div></div><div dir="auto"><div></div><div><div></div></div></div><div dir="auto"><div><pre>1. Arm SIMD optimizations: Several time-consuming scalar C functions now have SIMD implementations on Arm platforms. Existing Arm SIMD implementations have also been optimized. These optimizations result in up to 57% faster encoding compared to release 3.6.
</pre></div></div><div dir="auto"><div></div><div><div></div></div></div><div dir="auto"><div><pre>2. Arm SIMD optimizations include use of Armv8.4 DotProd, Armv8.6 I8MM, and Armv9 SVE2 instruction set extensions. The following algorithms now have optimized SIMD implementations: SAD, SSE, DCT, SAO, convolution, quantization, intra_planar, intraFilter, intrapred DC and IDCT16x16.
