[Mp4-tech] BitRate

[ramirez alejandro]

  Dear all,
  I am trying to do some experiments using the JM-9.5 H.264 software reference for baseline and main profiles for different bit rate values (10kbps, 64kbps, 128kbps, 768kbps and 2Mbps) . For that I am coding some test sequences (qcif, cif) using the reference encoder. 
  In special I want to know how can I control the bit rate?
  What I did is :
  In the bin’s directory of the software JM, there are two files called encoder_baseline.cfg and encoder_main.cfg.
  In the section under Rate Control,
  I changed the parameters value:
  RateControlEnable    =      1   # 0 Disable, 1 Enable
  Bitrate              =  768000   # Bitrate(bps)
  InitialQP            =     24
  For the bitrate parameter I tried for 10kbps,64kbps,128kbps,768kbps and 2Mbps. In all the cases the Bitrate wasn’t respected.  (stats.dat) for example: 
  For this bitrate:
  Bitrate              =  10000   # Bitrate(bps)
  In the stats.dat I had:
  Freq. for encoded bitstream  :   10
  Total Bitrate(kb/s)          :  24.29
  I will appreciate if some one can give me some examples about the configure file (.cfg) or some comments about it.
  Thank you very much!
  Alejandro
