None frames are not caught

Hi
I have an RTSP camera which is secured with a username and password. This causes the connection to fail with the error

Failed to connect to source rtsp://192.168.1.221:554/11.

This issue indicates there is no frame data, which could be caught, and an appropriate exception raised.

Hi,

What exception do you want to use here? Would no frame data indicate failed authentication?

Else let's close this issue, it seems you found how to use your credentials in the connection string.
