Pssh error

[aletaladro]

Hi friends, I am trying to obtain the pssh of some mpd but it turns out that they all give me the wrong no when I try to obtain the keys.



I only have an original pssh and I only have the mpd, I do not have access to the account to obtain through eme logger
PSSH:

The pssh I get with the kid is this one but it doesn't work either

this is the mpd,For the browser to detect it, it is necessary referer

This is what the mpd contains, that pssh does not work for me to obtain key

Did not think that people still had challenges with pssh. There are numerous threads that discuss this issue.

Looking at your first pssh

AAAAYXBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAAEEIARIQ2HZYMzRjTP+oc/eAqdLhmRoFQ29uYXgiJGQ3ZDE3NDVkLWMxNTYtNGNlOS1hN2M5LWIwMTUyZGEwZjIyYg==

This decodes to

Widevine Pssh
{
"algorithm":"AESCTR",
"keyIds":["2HZYMzRjTP+oc/eAqdLhmQ=="],
"provider":"Conax",
"contentId":"ZDdkMTc0NWQtYzE1Ni00Y2U5LWE3YzktYjAxN TJkYTBmMjJi"
}

The second pssh is totally incorrect. [AAAAMnBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAABISENh2WD M0Y0z/qHP3gKnS4Zk=]

You seem to have the correct pssh [first one]. Now you need the license server url plus the curl or fetch of the call. There are also numerous threads discussing this.

Keep reading and learning. Start with the stickies especially the ones by Angela.

Yes, the first one is correct but the problem is that I have 3 more mpd and I can't get the correct pssh. and if I try to get through the kid they are not correct

That pssh doesn't work, it's not the original. I'm looking for a way to get it without having to access the account, I have 3 mpd and the license, I need the original pssh to get the keys through pywidevine.

if your license URL doesn't contain token or something, then you probably need to login to get other parameters

only license and pssh is needed to get the keys, the only problem is the pssh I only get wrong pssh

based on "provider":"Conax", I highly doubt you only need license URL, I bet they have pre authorization variables just like trimi

I already obtained a key only with a license, trimi has nothing to do with this issue, it is very different
