Hi Adithya,

Thanks for ur reply,

I understand what are the structures required to enable ROI. But the problem is i cant understand how to pass "inars" and "outargs" to codec engine. I am using Venc1_create and Venc1_process. How to pass ROI arguments to these functions.

Hi Venu,

ROI parameters in inargs are the extended members. So you need use extended inargs structure, and you can pass this extended struct to Venc1_process call.

You can refer http://processors.wiki.ti.com/index.php/Extending_data_structures_in_xDM to know how to extend params(create time, runtime params, inargs, outargs etc..).

Thanks,

Veeranna
