If it worked, please explain to me how you got it so I can generate other keys please.

the pssh in the m3u8 is version 1, whereas the one i sent is version 0.
decode both here and compare the differences.

easiest way to convert from version 1 to 0 is to:
- decode it (as above)
- click the base64 button at the bottom in data
- copy the base64 data

- go to here
- choose:
- System Id: widevine
- Version: 0
- Data - base64: <paste the base64 data copied above>
- click generate
