Unable to (Re)install Widevine CDM library

[renato-alves-barros]

In Kodi, whenever I try to (Re)install the Widevine CDM library from within the inputstreamhelper plugin, I see the following error in kodi.log

Apparently there is something wrong with the URL:

$ cat /home/pi/.kodi/addons/script.module.inputstreamhelper/lib/inputstreamhelper/config.py | grep LACROS_LATEST
LACROS_LATEST = "https://chromiumdash.appspot.com/fetch_releases?channel=Stable&platform=Lacros&num=1"

Because If I manually use the urlopen from urllib.request against that URL, I get the exact same 400 bad request error:

>>> from urllib.request import Request, urlopen
>>> response = urlopen("https://chromiumdash.appspot.com/fetch_releases?channel=Stable&platform=Lacros")
Traceback (most recent call last):

    response = self.parent.error(

    return self._call_chain(*args)

    result = func(*args)

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 400: Bad Request

Perhaps this URL is no longer the correct one?
Appreciate any help with this issue.

Google apparently completely removed the Lacros images now as their support ended already last year: https://support.google.com/chromeos-beta/thread/284972520/ending-support-for-lacros-experimental-version-of-chrome-browser-for-chromeos?hl=en
So, I removed the extraction from Lacros images completely in InputStreamHelper Add-on.
From now on Widevine on ARM can only be extracted from the Chrome OS images:
Please test the following package:
script.module.inputstreamhelper-0.8.3-removelacros-9095f14.zip

Tested it and it’s working!
Many thanks for such a quick solution.

Worked on my machine :)

This seems to affect also existing installations (at least mine) where the regular update check fails and even breaks the playback then. So it would be nice if you could release the file above as some kind of 0.8.3.1. Thanks for the great work!

A new version 0.8.4 is released: https://github.com/emilsvennesson/script.module.inputstreamhelper/releases/tag/v0.8.4
But no yet merged in official Kodi repo: xbmc/repo-scripts#2776
