Set timeout for RTSP

[Tulesha]

Description

I am trying to open an RTSP connection to read a video stream and display it in the application using the VideoCapture.Open method. If the server is offline or the connection link is invalid, a problem with a long connection timeout occurs (about 2 minutes in my application). This problem has already been described in issue #1701, but it was closed because no one responded to it.
Is it possible to somehow influence the timeout so that there is no such downtime?
