It looks like x264_encoder_reconfig() allows changing some but not all props on
the fly. Bitrate can be changed if in VBV mode

    /* VBV can't be turned on if it wasn't on to begin with */
    if( h->param.rc.i_vbv_max_bitrate > 0 && h->param.rc.i_vbv_buffer_size > 0
&&
          param->rc.i_vbv_max_bitrate > 0 &&   param->rc.i_vbv_buffer_size > 0
)
    {
        COPY( rc.i_vbv_max_bitrate );
        COPY( rc.i_vbv_buffer_size );
        COPY( rc.i_bitrate );
        rc_reconfig = 1;
    }

Anyway either setting a prop could immediately reconfig, I guess, or x264enc
could have some kind of "need reconfig" flag that it handles on the next
buffer?
