Subject: [FFmpeg-devel] [PATCH v3 0/7] avfilter/vf_bwdif: Add aarch64 neon functions
Date: Mon, 3 Jul 2023 19:04:03 +0000
Message-ID: <20230703190410.237473-1-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 v2:
coeffs moved into const segment
number of patches reduced
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 Exports C filter_line
needed for tail fixup of neon code
avfilter/vf_bwdif: Add a filter_line3 method for optimisation
avfilter/vf_bwdif: Add neon for filter_line3
