I need help download lectures from https://ww.pw.live . I have the subscription for now but want to keep the lectures for future reference.
It was easier to download before as the link was to be modified a little and it would download through yt-dlp. They have recently changed their cloudfront servers and the old method does not work.
A new method was shared in YouTube but it only allows downloads through 1DM app on Android and through a telegram bot. It uses the following website 'https://psitoffers.store/1dm.php?vid=[VIDEO_ID]' to add some Policy ID, Key pair ID, Signature to the original link. When I paste this link into yt-dlp it throws 403 Forbidden error.
I have checked the DL links in 1DM. The Policy ID, Key Pair ID remain the same while the Signature changes for each lecture. How can I generate my own or get them from the browser, and pass it to yt-dlp for batch downloading? I saw a section named Policy, Key Pair ID, signature in cookies but they don't have any ID value.
I don't know what streaming method they use but it shows as octet-stream in the network tab.
I tried asking the dev of the new method, but he won't reply anything.
Please refer me to any other resources that may help me with this.
