Description
The function starts the rtsp streaming feature of the video application from a given URL to a specified video dialogue. Successful connection establishment and errors during connection establishment to the RTSP streaming source are reported asynchronously via onStreamStateChanged().
Note that when using authentification in the url (e.g.: rtsp://username:password@1.1.1.1:554) some camera manufacturers cannot process some characters. e.g.:
Axis cameras (e.g. model Q1615 Mk III and above) may encounter issues where the URL is marked as invalid when the # character is used in the username or password.
