Trying to access Prefs in URL service not working

Dev Community Dev/API Corner
1

I am trying to access one of the plugins user preferences with Prefs[“FORCE_BEST_QUALITY”].
This works in init.py, but not in my URL services.
It returns a KeyError: “No preference named ‘FORCE_BEST_QUALITY’ found.”
That is weard, because when i test it in my init.py it does work.
Is it even possible to access the Prefs in an URL service? Or am I doing something wrong?

You can watch the code in my GitHub repo or below. Please make sure you are looking at my “dev” branch if viewing on GitHub.

Brightcove URL service:

if Prefs["FORCE_BEST_QUALITY"] and stream["width"] > prevBestWidth:
    mo = []
    prevBestWidth = stream["width"]

DefaultPrefs.json

[
  {
    "id": "FORCE_BEST_QUALITY",
    "label": "Force best quality",
    "type": "bool",
    "default": "false"
  }
]

This is an question for the Channel Plugin Development section of the forum.

So I am moving this post to that section.

Channel prefs are set in DefaultPrefs.json. If you want URL Services to have preferences, you can add a file ServicePrefs.json to your URL Service folder (example).
