Key IDs and the content ID cannot be used at the same time.

Hi! Thanks for a nice app. On a page https://tools.axinom.com/generators/PsshBox i really need to generate pssh with key id and content id. How to avoid internal check that does not allow me to do it?

Could you explain why do you need it?

Google says that key IDs and the content ID must not be used together at the same time. I think it's because this may confuse license servers, so they won't be able to correctly decide which keys to return in the license response. Allowing this would make it possible to generate invalid PSSH boxes, which this tool tries to avoid.

The reason is that our key server works in such way, it is need two parameters, i got it that it is not correctly but please dont stop generator to prepare pssh, i think that ERROR or WRANING message is enough

@vladimir-kazakov if it is possible?

[vladimir-kazakov]

I don't like the idea of generating invalid PSSH boxes, but I see an interesting use case of doing so - making it possible to generate invalid content for testing purposes.

This will be done, but later this year. I can't be more precise right now, but I wouldn't expect anything until the end of summer this year.

Currently, there is no workaround for what you want to do. For now, you could try:

• Another PSSH box generator. Shaka Packager, for example, has a standalone one. I've never used it before, so I can't comment on how useful it is and its limitations.
• Generate Widevine PSSH data yourself by using its .proto file (this is Protocol Buffers), and pass it to the PSSH box generator in the Base64 or Base16 (hexadecimal) form.

@kuznetcoff777, I'm not working at Axinom anymore.

P.S. Maybe @KristjanJ or @Heronyme will be able to help you.

Hi @kuznetcoff777 ,

As mentioned earlier, you can use Shaka Packager to generate the PSSHbox as you needed. You can refer to our sample in the portal
where it does have a sample PowerShell code you can refer to generate the PSSHBox also. https://portal.axinom.com/api/download/use-shaka-with-axinom-key-server.
Hope that information will help you to get yours customized.

Thank you.
