Using n_m3u8dl-re to download by running

Now I have tried using Pywidevine and other tools here (Widevine guesser, Widevine fetch) to no avail. I'm mainly getting 403 HTTP forbidden errors. Any tips?

You need a new token (from 'https://adtv.ae/api/biz/video/playinfo') for every license request.

Thanks a lot!


Could you please let me know how you managed to get the keys? I had the URL, PSSH, KID but could not extract the key to use with mp4decrypt

I already explained how I got them. Everything is done via script. If you want manually, try one of the key extractors from the sticky threads and block the license request so that token isnt consumed.

Thanks I was kinda intrigued to try the manual method and managed to get it work.

Really loved your tool! It made things much easier, thanks again for your help.
