OpenCV VideoCapture.open() IP Camera unstable...

edit

Hi, all:

Environment: OS: Ubuntu 12.10 OpenCV: 2.4.9 SVN

VideoCapture.open(URL) sometimes successfully open the IP camera and starts streaming from URL. However, it's not very stable. Sometimes, it fails. The most probable reason is: the streaming from the certain URL hasn't closed the connection yet.

Any recommendations to open an IP camera stream (URL) ? Maybe, not use OpenCV to do this?

Cheers Pei
