you copy the standard params here, but you do not update the size, no?
you need to do:
ext_params.videncParams.size = sizeof(IMP4VENC_Params);
/* Set Dynamic Params */
#if 0
ividEncfxns = (IALG_Fxns *)hEncode->fxns ;
status = ividEncfxns->algControl((VIDENC1_Handle)hEncode, XDM_SETPARAMS,
(VIDENC1_DynamicParams *)& ext_params,
why would you pass the extended Params as DynamicParams?
