[Mp4-tech] [h264] coding parameters for HD

[Sassan Pejhan]

Hi,
In the encoder config file there is a section
under Rate Control, where you can enable Rate 
Control and set the Bitrate to the desired value.

Is there a WAY we can control the BIT Rate of the
encoded output using JVT reference software? 
Is encoded bit rate always depend upon the content of
each frame?
