How can I generate pssh if no kid in manifest?

[Musito]

Hi!

I have found a manifest that has no pssh or kid, how can I generate it?

https://ncdn-live-pctv.pfd.sfr.net/sdash/LIVE$RMCSPORT1/index.mpd/Manifest?start=LIVE&end=END&device=dash_dyn_wide

I have installed an add-on in chrome and it shows me the pssh in console but I would like to know how to generate it.

This is pssh generated:

Thanks!

If all else fails, you can download the init or a test fragment and use mp4dump to find the KID.

I already had the key, I just wanted to learn how to generate the pssh only but thanks!

I got the kid with mp4dumper and I generated pssh in: https://tools.axinom.com/generators/PsshBox but I don't get the same pssh.

If I decode pssh I got in console in: https://tools.axinom.com/decoders/PsshBox I can see this error: The "content ID" and the "key IDs" fields must not be used at the same time. Remove one of these fields. How can I generate pssh using content id and kid to generate the same one?

Thanks!

I got the kid with mp4dumper and I generated pssh in: https://tools.axinom.com/generators/PsshBox but I don't get the same pssh.

that's true maybe not the same length , but did you even tried that pssh to see if it give you the same kid:key to check if it is valid ?
this is the pssh generated via:

https://tools.axinom.com/generators/PsshBox

vs the one you got from console:

another way to generate the pssh is to use this script (thanks to [ss]vegeta):
https://forum.videohelp.com/threads/406769-Key-help#post2665689

and yes there is another script that looks inside the encrypted file and get the pssh and kid from the file which is found in getwvkeys discord channel.

maybe someone know how to pass SFR geoblocking?

Those two PSSHs have the same KID in.
The difference between them is that the longer one has this information in it too:

hex:   736672
Provider: sfr
hex:   61613862653437612d666263652d323962342d653035332d336232383435306137326466
ContentId: aa8be47a-fbce-29b4-e053-3b28450a72df

The 'ContentId' is the KID, with some '-'s thrown in.

I'm not familiar with axinom, but I'd be surprised if it couldn't add the provider and content id to generate the longer of the two PSSHs for you.
