How to set Dynamic targetBitRate of Enc_Link using Venc_setDynamicParam?

Hi All,

I was working on IPNC_RDK 3.5 version. when I try to set targetBitRate as dynamically
using Venc_setDynamicParam API, the below error message i was getting.
   

This Venc_setDynamicParam(1, 0, &params, VENC_BITRATE); API I was calling after Venc_start()
function.

Error Message

----------------------------------------------------------------------------------------------------------------------------------------------------

 [m3video]  ENCLINK: new targetbitrate to set:4000

of this issue?
