video url?

[nike1999]

I have obtained the correct pssh on chrome, and obtained the correct key, but the 4K channel needs to use the EDGE browser, and I cannot obtain the correct PSSH when using EDGE

HKVPN and use edge test, Chrome is OK

if it only works in Edge for 4K content, is it likely using PlayReady for 4K and not Widevine. I'm not sure, but it sounds like that might be the issue

That EDGE lic url confirms it is indeed PlayReady not Widevine

Can I get the key?

[CrymanChen]

PlayReady is relatively not public, but if you know the techniques, I would also like to learn.

Two types of encryption are used at the same time, can some data be obtained during edge playback and then decrypted by Widevine?

[nike1999]

Or disguise chrome as edge? Make 4k video playable in chrome? I don't know if this is possible

[Karoolus]

no and no

[CrymanChen]

It's impossible to use the two DRMs simultaneously, in other words, you can't use Widevine and PlayReady at the same time. It's not realistic.

Your second question, disguise Chrome as Edge. Even if you have finished doing so, Chrome doesn't have PlayReady CDM so it'll also be useless.
