Hello and thanks for the help. I have done this previously but did not
know how much the backend was involved.
Here is the output from a debug session. From what I can tell HasLock
never returns Yes. Is it possible to debug this part even further?
Since it works directly with streamlink there seems to be a difference
in how it locks to the stream?
