In h264 Spec, the SPS VUI.hrd.bit_rate_value_minus1 is a ue(v) and
"bit_rate_value_minus1[ SchedSelIdx ] shall be in the range of 0 to 2^32 − 2".

more details in the Spec E.2.2 HRD parameters semantics http://www.itu.int/rec/T-REC-H.264-201610-S/en page 424.

In this case, I think call set_ue_golome() will overwrite the bit stream buffer 
when SPS VUI.hrd.bit_rate_value_minus1 >= 2^16.
