For example, this video is just encrypted.

This is the m3u8 link:

but it shows like that:

not support SAMPLE-AES encryption

Could anyone plz tell me how can I work out the key of this kind of video? Thanks so much!

And these are the two m3u8 files which were created when I use the m3u8 link above to download video. And I change the suffix as .json file which could be easily opened in notepad++.

It is drm encrypted so you need to get license key. Use this key and decrypt the video

Hi, thanks for your kind reply~! But could you please be so kind to tell me how can I find the key? Because I'm use this website frequently, so I usually has TV series to download and don't want to bother the users on the forum frequently... Thank you so much~!
