Error in RTSP Audio capturing through gstreamer

[dananjaya]

I am trying to capture audio and video rtsp stream from gstreamer through
Jetson Nano. I am able to capture the video but when trying to capture audio
I get the below error.

Missing element: MPEG4-GENERIC audio RTP depayloader WARNING: from element

How can I resolve this error?
