Subject: [FFmpeg-devel] [PATCH v4 0/7] avfilter/vf_bwdif: Add aarch64 neon functions
Date: Tue,  4 Jul 2023 14:04:38 +0000
Message-ID: <20230704140445.240426-1-jc@kynesim.co.uk> (raw)

Also adds a filter_line3 method which on aarch64 neon yields approx 30%
speedup over 2xfilter_line and a memcpy

Differences from v3:
Remove a few lines of neon in filter_line that should have been removed
when copying from line3

Sorry about the two patch sets in quick succession, but I think I've
applied all the requested changes and I didn't want this mistake in the
final patchset. (The mistake was benign - it just wasted a few cycles.)

John Cox (7):
  tests/checkasm: Add test for vf_bwdif filter_intra
  avfilter/vf_bwdif: Add neon for filter_intra
  tests/checkasm: Add test for vf_bwdif filter_edge
  avfilter/vf_bwdif: Add neon for filter_edge
  avfilter/vf_bwdif: Add neon for filter_line
  avfilter/vf_bwdif: Add a filter_line3 method for optimisation
  avfilter/vf_bwdif: Add neon for filter_line3
