user/pass not provided

Error message

user/pass not provided

What it means

RTSP client Do auth guard: the server answered 401 Unauthorized, the auth method is AuthNone, and ReadNone could not extract credentials from the response — combined with no user/pass having been supplied in the URL. The server demands authentication that the client cannot provide.

Solutions

  1. Add username:password to the RTSP URL (rtsp://user:pass@host/path)
  2. Check for typos in credentials — wrong credentials raise 'wrong user/pass' instead
  3. Use a source without auth if the camera allows anonymous access
