* rc_mode - rate control mode

* 3 - balance mode : balance quality and bitrate 50 to 50
* 4 - more bitrate mode: bitrate parameter takes more effect
* 5 - only bitrate mode: only bitrate parameter takes effect
*
* mpp provide two rate control mode:
*
* Constant Bit Rate (CBR) mode
* - paramter 'bps*' define target bps
* - paramter quality and qp will not take effect
*
* Variable Bit Rate (VBR) mode
* - paramter 'quality' define 5 quality levels
* - paramter 'bps*' is used as reference but not strict condition
* - special Constant QP (CQP) mode is under VBR mode
* CQP mode will work with qp in CodecCfg. But only use for test
