Downloading a Video played by JW Player 8.8.2 and other Protections

Im trying to download a Video from a webside where all of the default stuff wont work.

The Video is played by JW Player 8.8.2

I was able to surround the human verification and got this link: https://topsf.club/public/dist/index.html?id=304528750dad84ba909a41adb5d428b0

If you have a look at the title of the window you see, that the stream works using P2P Drive - VanLong Streaming

After searching i found out that the stream reaches the webside in parts from google drive

On the original webside I found a blob url:blob:https://topsf.club/1acd11e7-5fda-4d0b-9af7-667c199a251c which is greyed out in my Firefox Website Information.

I wasnt able to find a m3u... file in my request history

I thought might I could write a programm that combines those google drive files: By having a look in the request history of my browser you can see: Heres the Image

The website sends a request to topsf.club which looks like this: https://topsf.club/getChunkLink?chunkFile=af5512cfaf24c6e37c4e38850a3af74b-chunk-26.txt&t=1583667823544

If you follow the link you can see, that the website just contains another link which looks like this: https://www.googleapis.com/drive/v3/files/1zw19v_Lr8_SNVmaebjuCVlGR2XiDnnZ7?alt=media&key=AIzaSyDuvvwb7HBdf8lkoMDpwf7VTh1evn6nmXo

By following this link I got a download request for a application/octet-stream which, if I got it right means, that the file has no ending but might it would be helpfull Image: Download request

I have no idea how to get my video in a format like mp4 saved at my drive. I would be really greatfull if somebody could explain me how to reach this goal. I think the easyest way would be to download all part files and combine them.

But at least i want to say, that Im no web developer so sorry if I wont get everythink right Thanks to you all
