Obtaining PSSH

Obtaining PSSH

Getting started

4 methods to find PSSH:

  1. The simplest one: PSSH is clearly indicated in MPD file. Download MPD file (browser add-on "MPD Detector" will give you MPD link or filtering for mpd in the network tab of devoloper tools (ctrl + shift + c)), open it with Notepad, search for pssh value.

  2. If there is KID, but no PSSH in MPD, calculate PSSH by using KID:

Using this website you can get the PSSH by entering in the urn:uuid: into the System ID field and entering the cenc:default_KID= into the KEY IDs field without the quotes ""



  1. EME Logger Script (installed on Tampermonkey add-on) will give you init data. That's your PSSH. This can be found on Developer Tools (ctrl + shift + c) > Console, in the filter bar search for MediaKeySession::generateRequest you will find Init Data.

Optional, may be rquired:

If that Init Data is very very long, convert it to HEX: https://base64.guru/converter/decode/hex

Here's what mine looked like before conversion. Two:

After Base64 > HEX conversion, you will find a Widevine-PSSH box, this can be found easily by searching with ctrl + f and searching for 70737368

PSSH header is always in a 000000xx70737368 where the xx is varied and can be from 1-9 in both x spots. You always want to copy the 6 0's before the xx as well.

Example: Three:

The end of the header is always then followed by 8 more 0s, if you see this, you are in the right place.

Once you find the header start at the beginning 0 from the header and copy until the end of the converted hex, it should look like this

Example: Four:

In this case the full value was 000000577073736800000000edef8ba979d64acea3c827dcd51d21ed0000003708011210162f7d326cf24f6dbd1319bc572bbc151a0b62757964726d6b65796f732210162f7d326cf24f6dbd1319bc572bbc152a024844

convert the hex back into base64 using https://base64.guru/converter/encode/hex

Example: Five:

In this case we got the PSSH value of AAAAV3Bzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAADcIARIQFi99MmzyT229Exm8Vyu8FRoLYnV5ZHJta2V5b3MiEBYvfTJs8k9tvRMZvFcrvBUqAkhE

Congrats, you have the PSSH!

  1. Using init files
