Hi Matt,
Thanks for quick reply,
I have one more quick question, i will install suggested sdk & cuda libs and
set the necessary path.(as i did for Jetson tx2).
*i am using gstreamer api code, is this a correct way to approach.*
I have to still modify the code to read from buffer and audio encode
support.
*Below is my code.*
