Help: How To download Encrypted videos from Jwplayer

[hamada_mohamed]

I was checking some videos on an educational website and the first video seems to be relatively easy to be downloaded. It turned out that this is the promo video and they kept it available for everyone

The other videos are encrypted


After some checking.

I found MPD File, And the Keys using Winevine.

I used m3udl GUI to download the MPD. I couldn't download the MPD file at first. Then I tried adding some headers (This is my first time; I could have done it wrong). It successfully downloaded and later decrypted.

After that, I couldn't download any file again and probably they disabled my ability to view any video.

Is there a way to download successfully without compromising my account.

write here video link that you want

[codehound]

For this video - as an example https://calcworkshop.com/limits/finding-limits-graphically/

Best video:

yt-dlp -f f4-v1-x3 --allow-u --referer "https://calcworkshop.com/limits/finding-limits-graphically/" "https://zstream.calcworkshop.com/coffee/C1_01-Finding-Limits-Graphically/,400,800,1200,1600,.mp4.urlset/manifest.mpd"

Only audio:

yt-dlp -f m4a --allow-u --referer "https://calcworkshop.com/limits/finding-limits-graphically/" "https://zstream.calcworkshop.com/coffee/C1_01-Finding-Limits-Graphically/,400,800,1200,1600,.mp4.urlset/manifest.mpd"

Decrypt separately
Merge decrypted parts with ffmpeg

tested = ok but takes forever

You could use aria2c.exe to aid download speed, put it in same folder as yt-dlp.exe

https://www.mediafire.com/file/h16fq91bpzk0lhp/aria2c.exe/file

yt-dlp -f f4-v1-x3 --allow-u --external-downloader aria2c --referer "https://calcworkshop.com/limits/finding-limits-graphically/" "https://zstream.calcworkshop.com/coffee/C1_01-Finding-Limits-Graphically/,400,800,1200,1600,.mp4.urlset/manifest.mpd"

Only audio:

yt-dlp -f m4a --allow-u --external-downloader aria2c --referer "https://calcworkshop.com/limits/finding-limits-graphically/" "https://zstream.calcworkshop.com/coffee/C1_01-Finding-Limits-Graphically/,400,800,1200,1600,.mp4.urlset/manifest.mpd"

But better to get access to the website

I tried the exact same code and I got this

I also tried your command line with another website and it seems working just fine. Not sure if the problem is with the math website or my pc got flagged from their system.
