Rémi Denis-Courmont 5a6e333fc7 lavc/h264dsp: R-V V 8-bit luma loop filter ... T-Head C908 (cycles): h264_h_loop_filter_luma_8bpp_c: 297.5 h264_h_loop_filter_luma_8bpp_rvv_i32: 369.2 h264_v_loop_filter_luma_8bpp_c: 862.7 h264_v_loop_filter_luma_8bpp_rvv_i32: 199.7 Performance in the horizontal scenario seems worse than scalar. x86 SSE2 and AVX optimisations are similarly affected. This is presumably caused by unlucky inputs from checkasm, such that the C code short-circuits almost all filter calculations.		6 months ago
