Heesuk Jung 25b7aa980b Fix bit_rate in MPEG1/2 Video
In ISO/IEC 13818-2, bit rate is differently determined according to video type

1) MPEG1 Video
 Bit_rate and vbv_delay are set to 3FFFF and FFFF respectively
 to indicate variable bitrate. Other values are for constant bitrate.
 VBV is only defined for constant bit rate operation.
 Ths STD supersedes the VBV model for vbr.

2) MPEG2 Video
 Even if the bitrate is constant, the value of bit_rate may not be the actual bitrate
 since bit_rate need only be an upper bound to that actual bitrate.
 VBV is only defined for variable bit rate operation.
 Constant bit rate is viewed as a special case of vbr.
