Operation Not Permitted error while streaming using rtsp protocol

[PrasannaMishra1]

I developed an Android app to stream live video from IP camera through NVR. The app was not working on Naugat. After upgrading Vitamio version to 5, I am able to play feed from only one camera. For others the error in Logcat is :

E/Vitamio[5.2.0][Player]: [rtsp @ 0x7f76133e00] method PAUSE failed: 551 Option not supported
E/Vitamio[5.2.0][Player]: av_find_stream_info: Operation not permitted : -1

I am using the URL of the form rtsp://user:pass@IP:port/Streaming/Channels/2/trackID=1. HIKVision IP camera is used in the premises.

I am not able to find any information on what is the error. But occurs only in Naugat phones. Works fine with older version of Android.
