dct_unquantize_h263_inter_c:                           417.8 ( 1.00x)
dct_unquantize_h263_inter_rvv_i32:                      66.0 ( 6.33x)
dct_unquantize_h263_intra_c:                           140.2 ( 1.00x)
dct_unquantize_h263_intra_rvv_i32:                      67.7 ( 2.07x)

Note that the C benchmarks are not stable, depending heavily on the
number of coefficients picked by the RNG. The R-V V benchmarks are
however very stable and generally better than C's.
