    Stop using VP9 convolve scheme in AV1 encoder. · 1fc3df55
    Debargha Mukherjee authored
    Discontinue all VP9 style convolve rounding operations in the non-normative
    parts of the encoder.
    
    The function av1_convolve_2d_sr_c is forced instead of SIMD versions
    of the same function, because of incompatibility when round_1 > 0.
    
    In the -DCONFIG_LOWPRECISION_BLEND=2 -DCONFIG_HIGHPRECISION_INTBUF=1
    setting, results on 15 frames of lowres (cpu-used=1) is -0.019% better.
