[vitalka]

hey folks,

Crunchyroll have free content, so this topic should be fine i think.
Im trying to get a working kid:key by playready C# class: https://git.gay/ready-dl/csplayready

In the .mpd manifest i have these cenc: pssh and mspr: pro:

For playready of course i use the mspr: pro, it is the one which is working. in csplayready class the example is with pssh, but with pssh it isnt working. im a bit confused. if i see right larley is dev of it, maybe you can explain it to me.

This are the two license server for Crunchyroll:

  license_wv: https://cr-license-proxy.prd.crunchyrollsvc.com/v1/license/widevine
  license_pr: https://cr-license-proxy.prd.crunchyrollsvc.com/v1/license/playReady

With both i get kid:key, but the one with playready and mspr: pro isnt decrypting right. With Widevine and pssh its working fine.

Why im getting with playready a kid:key, which isnt working?

the <cenc:pssh> element can appear in both ContentProtection elements but depending on where it's located it'll either contain a Widevine or PlayReady PSSH

You are Right. The kid from playreadyserver is the one, which is used for widevine. If I Place only key without kid in n_m3u8dl_re its decrypting right. Really Strange.
