I just had a short look.

version=2 seems to be disabled on purpose somehow:
line 1010:
    av_assert0(s->version>=2);

And is this really scaling on a modern cpu? This reads like it supports max 4 threads:
    if(s->version>1){
        s->num_h_slices=2;
        s->num_v_slices=2;
        write_extra_header(s);
    }
