Help downloading some videos

[oxoxen21]

Hello! I'm new here, and I'm trying to learn yt-dlp to download the episodes of this show: https://www.ctv.ca/shows/muddling-through

I want to download them to put them to a DVD for a family member who worked on the production of the original show. We're trying to put together sort of a compilation of all the things he ever worked on, for a Christmas present (he's retired and isn't in good health).

Anyhow, I know from browsing this forum that CTV stuff is DRM-protected, but it seems like a few folks have had some success getting a few things from there. The CTV site doesn't require a login or account to watch the videos. When I follow the directions for downloading with yt-dlp, I get a message that "this video is DRM protected".

I confess that I'm not very savvy in command-line stuff or scripting/coding (one of the other threads dealing with a CTV request mentioned needing to know some of that stuff). Can anyone point me to a resource where I can fill in the blanks and work out how to capture these videos? I don't want to distribute the videos or anything; I only want to present them to my uncle for a private memento.

Thanks in advance to anyone who reads this and might offer some help!

http://getwvkeys.cc/ you need this site for getting the keys so you can decrypt the encrypted content that you will download.

Download these and put them in some folder (these are used for downloading, decrypting, merging video and audio)

and go to the add-on, click "Create New Script", paste the code there and click file -> save
You need to do this so you can get the PSSH from console of browser, otherwise you won't have those codes in the console.

The whole process is shown in the following video.

I join a @Brook_Benton's thanks for your video tutorial.
Could you also explain how to use WKS-KEYS scripts.My first attempts resulted in an error

I don't know what to say-- this is like magic! It's working perfectly! I'm so excited-- I really thought we weren't going to be able to get these videos, but everyone in my family is going to be thrilled.

THANK YOU VERY VERY MUCH. You guys are amazing, and I owe you big.

I agree totally. Thank you for posting this link to a downloadable video. This guide is a total lifesaver and I couldn't be happier. My sincere appreciation to both of you and to this forum.

THANK YOU VERY VERY MUCH.

Thanks again for your your help the other day and for your kind words here.

As you know, the getvwkeys site we were using to decrypt the content is down. I've been trying to follow the discussion in the threads it's being discussed in, but a lot of this stuff is pretty technical from my standpoint and I'm having a hard time following it.

I hate to keep being a bother, but can you me in non-technical terms if there's an alternative way to get those keys? I've only been able to download a few of these episodes because the process is so complex (for me) and I've been waiting until I was back home to download the rest.

I totally understand if there's no alternative way to do it right now, but if there is one and it's something I can grasp and do myself, can you point me in the right direction? Thanks in advance for any help you can give and for all your time.

[[ss]vegeta]

Thanks in advance for any help you can give and for all your time.

Tell me the episodes you need keys from, I'll try to get you.

The first link is down for maintenence and the wetransfer file is expired. Could you reupload? Very curious to try this. Thank you.

Just followed the excellent instructions by [ss]vegeta, thanks so much for making them!

For anyone reading beefyboygod's comment, don't worry. The getwvkeys site is back and working at getwvkeys.cc, and the wetransfer link with a toolkit helpfully provided is not needed, you can just get the tools from normal sources with no problem (shouldn't be any news for most users of this forum?):

No problem. I updated the post with a drive link that shouldn't expire and I edited a short version of Eme logger that should display only the PSSH instead of all the other things.

Hey [ss]vegeta, thanks so much for this guide. I used it effectively on a new episode of Transplant here but was unable to download the rest of the season (getting unauthorized, 401 http errors), no matter what combination of logins for my paid Bell account I tried (with cookies-from-browser, with local cookies, with cookies and account login info, and just account login info). Any idea what the approach or syntax I should be using to get this right is?
Thanks again

No idea. Maybe some header/user agent?
Also, it's weird. If I open that link directly, it lets me watch.
However, when I try to go to it by navigating through the site, it requires login.
Send user/pass via private message so I can see what's happening.

Hey there, on getwvkeys.cc, I only get one key "1. 5dd......"
Some ideas?

One pair of kid/key might mean that it's for both video and audio, if they are both encrypted.
Or, you might need a different PSSH for getting audio decryption keys. I think this happened to me one time.

It seems to me that it turned out to be a very long PSSH

I went to the site http://getwvkeys.cc/.

But it gives me an error:

Error 404: <!doctype html><html lang="ru"><head><title>HTTP Status 412 – Precondition Failed</title><style type="text/css">body {font-family:Tahoma,Arial,sans-serif;} h1, h2, h3, b {color:white;background-color:#525D76;} h1 {font-size:22px;} h2 {font-size:16px;} h3 {font-size:14px;} p {font-size:12px;} a {color:black;} .line {height:1px;background-color:#525D76;border:none;}</style></head><body><h1>HTTP Status 412 – Precondition Failed</h1></body></html>

And gives me three keys:

[lomero]

you have try to decrypt with all keys?

mp4decrypt --key xx:xx --key xx:xx --key xx:xx <input> <output>

or maybe wrong key ...

[contello]

Thanks. It turned out that I entered the Headers incorrectly.
Now i can decrypt the video
