My Android app is not able to play RTP stream on Google Nexus 10, why?

[AC Question]

My Android app is not able to play RTP stream on Google Nexus 10

Hi,

I have Google Nexus 10 and I have rooted it. I have build my own video player app which I am typically using it to play H264 encoded RTP streams.
But I am not able to play the RTP stream on Google Nexus 10 using my video player app. However, I am able to play the same RTP stream using the same APK on other tablets like Google Nexus 9, Samsung Galaxy Tab4, and Microsoft Surface Pro 3.

NOTE:
I am able to play RTSP stream on using my app on Google Nexus 10 but not RTP stream.

But while playing RTP stream using my app, log shows:
udp_resolve_host: No address associated with hostname
LAVF_header: av_open_input_stream() failed

Is there any Firewall / app protection settings that I need to change to be able to use my app?
I have "Unknown sources" option checked under security-->Device administartion settings.

Thank you,
