Decrypt an offline RaiPlay video I downloaded which is DRM protected

[leonex2530]

Hi everyone!
I recently was able to download a DRM-protected video from RaiPlay thanks to a Chrome extension. I had some issues recently so I did not have the time to try decrypting it. Now that I can, the video is unfortunately no longer online. It was on two links:
https://www.raiplay.it/video/2024/07/TELEGIORNALE-36a0be76-0911-4a2a-83dd-df7a24a5deb1.html or alternatively https://www.rainews.it/notiziari/tg1/video/2024/07/TELEGIORNALE-36a0be76-0911-4a2a-83dd-df7a24a5deb1, the latter available archived on the WayBack Machine (I do not know if this can help or if the important elements to look at from the inspection tab are gone with the original video). Also, in the file property of the video I downloaded I find this information “drm_root/DRM_Nagra_TG1_RAIPLAY/23862857_,1800,2400,3600“. It has the good length and weight so I assume it actually contains the video, but as the page is gone I am not sure I may be able to retrieve the key to decrypt it. I have to admit that I am not such an expert in dealing with DRM, but I really need this video for a university project, so I extremely appreciate any help you may give to me. I can also upload the file on some platforms for you to download it to examine it. Thank you so much, have a nice day!

type in the date of the newscast you are looking for

[leonex2530]

Thank you for your answer! It is the TG1 broadcasted on the 27/07/2024 20:00 (8 pm)

I suggest you don't wait because things expire, it seems like the newscasts stay a month on raiplay

[leonex2530]

Yes I know you are right, I am usually always pretty on the spot with those things, but this time it went differently. Do you think there is a way to decrypt the video knowing that I have the actual file?

[nette]

didn't you mean to write https://www.raiplay.it/video/2024/07/TELEGIORNALE-36a0be76-0911-4a2a-83dd-df7a24a5deb1.html ?

[leonex2530]

I’m sorry, don’t understand what do you mean? Yes, it is the link I posted, if this is what you are asking.

Sei italiano tra l’altro, giusto?

[nette]

but at that time there was drm? i see the last tg has no drm

[nette]

you wrote https://www.rainews.it/notiziari/tg1/video/2024/07/TELEGIORNALE-36a0be76-0911-4a2a-83dd-df7a24a5deb1 two times. I'm italian


I can't help you, I think I did my best and you did your best too

[leonex2530]

Yes it is strange, only some were DRM at the time, I think because of the Olympic Games. Ah I am sorry, I copied both but probably ended up adding the same. I just edited the post, thank you for that

[nette]

you can try sending me the drm file ?

[leonex2530]

It is pretty large (1 gb) so tell me the method you prefer and I can upload it to share it with you. Thank you very much for your help!

Here it is: https://filetransfer.io/data-package/x23aSwW0#link

unfortunately I have problems at home, there is a fault in the line and so I am using an unsecured network, it is slow.

how long was the news cast?

[leonex2530]

Don’t worry, thank you very much again! 37:56 minutes

[nette]

is there another newscast with drm?

do you have the .mpd link of the newscast?

[leonex2530]

I was able to find something inspecting the archived page, but as I am not that proficient I was not able to properly deal with it. I though there were some mostly at the time of the Olympics!

[nette]

but do you have this file in your browser's download history?

[leonex2530]

Yes I downloaded some of the files I found on the archived page. I can send them to you if you want, but they are on that page

[nette]

the link type https://b70cb04c54ab478189e9d8ee45637b13.msvdn.net/ostr2/podcastcdn/drm_root/DRMNagra_...51ef5de509acbc

I took this from https://www.raiplay.it/video/2024/10/NCIS-S21E3-Come-unombra-29fe79bf-71a5-44ae-ad51-4...6c9abc912.html

or like this

you can copy from your browser's download history if you keep

[leonex2530]

I will check this out again, just a moment.

[leonex2530]

I found this link in the archived page https://mediapolisvod.rai.it/relinker/relinkerServlet.htm?cont=mw8QSvmoajJ9j5UlUkZQywe...qualeeqqEEqual, which redirects us to this other link which looks like the ones you posted.

[leonex2530]

So you were able to decrypt it?

[nette]

I'm trying, I still have the line fault, do you have nm3u8DL-RE?

[leonex2530]

No, I don't. Should I download it?

[nette]

I don't know if I can use the unsecured network, it might interrupt too much and crash

[nette]

the procedure did not work, I'll try again
