• hey i need to download my coaching classes but they are using hls aes 128 bit encrypted streams. i downloaded m3u8 and all .ts files and found enc key

  19 mars 2023, par tinu one

  I downloaded all the .ts files using a python script but it is encrypted with aes 128.i found a encryption key (supposedly) under the network tab in developer options. I ran it through ffmpeg but got an error( invalid data found while processing ). I need these classes because they are going to remove it in may 2023. i am a noob to this and may have done step wrong. Please forgive me. I would deeply appreciate anyone who will help me find a solution to this problem. Thankyou.

  


  I downloaded all the .ts files and m3u8 file and put it inside a folder. I hosted the key file in localhost that I found under the preview tab of the network tab in developer options( it was named key/ after all and had characters which was not human readable. it also had the request URL similar to that inside the m3u8 file)because ffmpeg did not want to read the key file from my local pc. I edited the m3u8 file to access the key stored in local host and it read successfully. but it shows error( invalid data found while processing).

  


  encryption key from preview tab I found : Ø®¢Ù¦Aä [u
request url of the key : https://classes.brilliantpala.org/api/v2.5/video_contents/42475/key/
