when running checkasm several times sse2 is mostly faster here, not always.
But the difference is quite small.
Since I´m not an SIMD expert I´m fine with this patch as long as no one
with more expertise objects.

[FFmpeg-devel] avfilter/vf_interlace and vf_tinterlace : remove avx version

[Martin Vignali]

Hello,

Following discussion "avfilter/vf_interlace : add checkasm for lowpass_line
and AVX2 version"
the AVX version seems to be slower than SSE

Patch in attach remove it, for vf_interlace and vf_tinterlace (both use the
same SIMD)

Martin
