authentication on stream/ rtsp url

[smk-adiance]

How can I make my pulled RTSP stream play only when the correct static token is provided in the URL?

it worked for me when i last tried it with this code i have attached it:

config.yaml
but it is not working now, why so?

what token

[smk-adiance]

By token I mean a fixed string/key that I add to the stream URL, for example:
rtsp://my-server/live/stream?token=12345
Only if the correct token (12345 in this case) is present in the URL should the stream play.
Earlier, I tried setting this up in config.yaml with a static value, but now it doesn’t seem to work. Can you suggest the right way to enable authentication?
