Apologies for the delay, the review and smoke testing on our end took longer than expected. The changes have now been pushed. ________________________________ From: x265-devel <[email protected]> on behalf of Jonathan Wright <[email protected]> Sent: Tuesday, June 24, 2025 10:06 PM To: [email protected] <[email protected]> Cc: nd <[email protected]> Subject: Re: [x265] [PATCH 0/2] AArch64: Fix SVE DCT implementations
Hi, Could someone take a look at these patches please? Thanks, Jonathan ________________________________ From: x265-devel <[email protected]> on behalf of Jonathan Wright <[email protected]> Sent: 10 June 2025 18:40 To: [email protected] <[email protected]> Cc: nd <[email protected]> Subject: [x265] [PATCH 0/2] AArch64: Fix SVE DCT implementations Hi, This patch series fixes bugs in the Arm SVE 16x16 and 32x32 DCT implementations, and also mitigates a portion of the performance regression due to the fix. Both SVE DCT implementations are still sgnificantly faster than the equivalent Neon paths. Note that the DCT unit tests did not show these bugs. They were found after differences in encoded output videos were observed on Arm and x86 for veryslow, slower and slow encoding presets. With these patches applied encoded output matches for all speed presets.
