Need help for getting KID:KEY value pair

[jonax77]

Hi guys, I am a newbie and I learn a lot from this forum.

I tried to download video from vrt max. Everything went great but I failed in the decrypt phase. I guess the problem is I used wrong kid:key pair. I just simply copied the default_kid in the mpd file. Which didn't match the format in successful code.

I am using macos 13.0 and I use N_m3u8DL-RE and mp4 decrypter.

I follow this thread https://forum.videohelp.com/threads/407962-download-from-VRT-MAX
And tutorial https://forum.videohelp.com/threads/404994-Decryption-and-the-Temple-of-Doom

but I know it is currently out of my ability to get the kid:key pair. So I turn to you guys for help.

I hope I can get kid:key pairs for all 6 episodes...ORZ. If that bothers you, ep01 and ep03 is enough! Thanks in advance!

And one more questions, is the kid:key value pair unique for each video? Or I can use the website's key for all this season?

First thing first,
--key "2B72B3A7-9B0B-D9B6-A19F-C34DDE309A76" is totaly wrong set.
Use decryption key not kid, something like --key kid:key

Thank you for your help! Now I got some issue while trying extract subtitle from the video, could you please help me check with it?

The subtitle worked well in my video player but when I extracted it the size of the srt/vtt file was only 1kb containing about 10 sentences. I did some search on google but it seemed that nobody got similar problem. Thank you again in advance!
