Initializing stream with unknown KID!

[MPParsley]

I'm seeing this in the logs:

2021-02-01 19:57:50.187 T:1763201248 WARNING: AddOnLog: InputStream Adaptive: Initializing stream with unknown KID!

The manifest doesn't provide a default_KID:

@MPParsley I think this is related to this: #543 (comment)

It should be fixed by this commit: 30f3a74

Seems to the same as #593

This seems to be the underlying issue:

{"errorcode":371000005,"errormsg":"Widevine license acquisition failed >> Verified media path cannot be verified","errorid":"XXX"}

I could be wrong but I think your problem is due to VMP

in the past i have read of Verified media path on widevine page:
https://www.widevine.com/news
chapter: Browser CDM - Verified Media Path

some other has opened something related #405
I think that if your add-on does not provide a certificate to ISA
you should consider trying to add the certificate on ISA listitem property

Duplicate VMP issue
