Help downloading videos from a National streaming service

[ShadoWalkeR]

Hi,
I'm new to this, I'm trying to get a national series that's locked to my country and it's not available anywhere else for the streaming site: https://opto.sic.pt/
I learned how to do most things and can get all info needed, but I'm having trouble downloading the encrypted data.

This is what I already have:

Ok, so you'd think I'm set right? Nope, for some reason when i use yt-dlp to download the encrypted data I get this error:

ERROR: unable to download video data: [Errno 13] Permission denied: 'manifest [manifest].ff4-a1-x3.m4a.ytdl'

This error occurs on the audio file, so right now I was able to get the encrypted video and fully decrypt it with the key I have, but I can't get the audio.
Anyone knows what's causing this?

I'm using this command to download from the .mdp

yt-dlp.exe --allow-unplayable-formats "my-mpd-link"

Thank You

Hi,
Between the post coming up and now i managed to solve this problem.

What I did was use aria2c and this command instead:

yt-dlp.exe --allow-u --downloader aria2c -f bv,ba "mpd-link"

Hi,

How did you managed to get the key from opto.sic?
I'm trying to get it to decrypt my files.

[libero08]

Is very simple , you need a cdm or subscription on discord getwkeys.

[rafman]

Many thanks
Great, I've asked for a verification already on their discord.

Ok, nice! Got this working now.
But it seems like it gives me a wrong key to decrypt one video. It's always giving me this key, and I rechecked 3 or 4 times already the license and PSSH. There's no way to decrypt with this key, is this possible? A wrong key? All others decripted with no problems.

if it plays in the browser then there is a correct key to decrypt it.
i assume you are getting it from getwvkeys, have you tried choosing the force option so it forces it to send the request to the license server?

I get it... I was trying with a wrong key, my bad... All good

Hi ShadoWalkeR, I tried use this command you shared, passing this MPD url:

https://cfvod.kaltura.com/edash/p/4526593/sp/452659300/serveFlavor/entryId/1_w1tu0hz5/v/1/ev/7/flavorId/1_,1e6hx6nu,00w0y4n6,yv9mynll,bywhnti3,ozcoe3gi,gh1yfmdj,/forceproxy/true/name/a.mp4.urlset/manifest.mpd

But it's giving me this SSL error all the time:

ERROR: [generic] None: Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:997)> (caused by URLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:997)')))

Can you please help me? Have I missed something?

Thanks

your code work fine. maybe update yt-dlp (with -U)

After updating the yt-dlp, the error stop happening.

Strange, because I thought that had already installed the latest version available on the GitHub.

Thanks a lot for the help lomero.
