Playback fails when InputStream Adaptive is updated

Describe the bug

This is a generic issue with Kodi / InputStream Adaptive which affects VRT NU, but it equally affects other add-ons that rely on InputStream Adaptive for playback (e.g. VTM GO or Netflix)

The problem is reported upstream at https://github.com/peak3d/inputstream.adaptive/issues/454

What happens is that the library is updated from version X to version Y, and this causes the library on disk to change name. Kodi does not pick up the new name, but keeps on using the old name which is not longer available.

Workaround

There are two options here:

• Disable InputStream Adaptive support in VRT NU. (This works only if you don't need DRM support)
• Reboot your Kodi when InputStream Adaptive was updated. (Unfortunately that is not always apparent)

Expected behavior

Kodi should be able to refresh the location of the InputStream Adaptive library when it is updated, so it does not look for the previous version.

Additional context

• Operating system: LibreELEC v9.2.1
• Kodi version: v18.6
• Addon version: 2.3.4 (but any version really as it is IA related)
• Using a VPN: no
• Country you are using the addon from: BE

Start with the upstream InputStream Adaptive issue linked in the report, then review the Kodi log showing the failed lookup for inputstream.adaptive.so.2.4.4 and the documented reboot workaround. Confirm whether the fix belongs in Kodi, InputStream Adaptive, or this add-on; done means playback continues after the library is updated without requiring a reboot.
