VOD TVP - decrypting

[dzimi]

Hello. I have downloaded video from VOD TVP. How do I get the key?
https://vod.tvp.pl/video/allo-allo,odc-1i,36171389

[pkp]

--key 2b68c114e55349a0b28f3963998d1f30:071c45d47b45b2c46dbc10fcce698b2a

It is just normal widevine stuff...except for the irritating ads

[dzimi]

Wow! Thanks bro! How do you do it?

[[ss]vegeta]

How do you do it?

Spend a few days reading the threads in this sub-forum to at least get the general idea.

What I'm doing wrong?

What I'm doing wrong?

Maybe you are missing a header, maybe getwvkeys can't work because site needs VPN/proxy or something.
Or maybe something else.

Hmm I get wrong ssl version number error or something with scripts and I get 403 on getwvkeys...
There seems to be a weird and uncomplete header
X-AxDRM-Message: eyJhbGciOiJIUzI1NiI...

that might be causing problems

maybe pkp would care to explain more

maybe try a different vpn server?

[[ss]vegeta]

maybe try a different vpn server?

Yep, it was that, after all.
Doesn't work with Nord VPN's one server I tried, but works with Windscribe.
Thanks.

[dzimi]

It isn't possible to get the key with getwvkeys?

[lomero]

if you have access to this site, you have also access to server chat
ask on chat

[karapuz]

It isn't possible to get the key with getwvkeys?

and anyway the answer to your question is no: you need a special script for your site

getwvkeys.py

      pywidevine-api 4.1

I tried without success to decode a video from the same site.

https://vod.tvp.pl/programy,88/kolo-fortuny-odcinki,273642/odcinek-1591,S01E1591,389156


I have tried the key 2b7eae0f3924448eb6d962da2ccfe8a0:d6ca0e7a03ad02d83 0d1fac4c60dac5b but it doesn't work ?

My method :

• I used chrome + tampermonkey + script to get the PSSH
• I convert / reduce the PSSH with https://base64.guru/converter/decode/hex and https://base64.guru/converter/encode/hex
• I used the page https://cdrm-project.com/ to obtain the key.
• I download the video with : yt-dlp --allow-u
• Finally, I tried to decrypt the video with Bento4 / mp4decrypt.

I used this data to obtain the key :

1. PSSH : AAAAO3Bzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAABsIARIQK3 6uDzkkRI622WLaLM/ooCoFQVVESU8=

I have also tried to decrypt with the key 1:d6ca0e7a03ad02d830d1fac4c60dac5b

No success !

Any idea ?

(My tools (yt-dlp / mp4decrypt) are OK because I can decrypt video from this drm demo site : https://bitmovin.com/demos/drm).

[ElCap]

that key works for me, maybe you downloaded the wrong file?
this is the manifest url i get
https://n-22-5.dcs.redcdn.pl/dash/o2/TVP/embeddrm/out/pr00f7ls-odc._1447_ed._12_17f6fe....ism?indexMode

[mohegan]

OK, thanks.

I understood my mistake !
I downloaded the video directly with yt-dlp @html adress (because it works with non DRM videos on vod.tvp.pl)

yt-dlp -F https://vod.tvp.pl/programy,88/kolo-fortuny-odcinki,273642/odcinek-1591,S01E1591,389156

So, yt-dlp download the best format : hls-4800 mp4 1920x1080.

But, when I verify the link on network on chrome, the best format available is only : hls-2800 mp4 1280x720.
If I look the video from the website, a button permit to change the resolution. 720p is the best resolution available.

I don't know why yt-dlp download a 1920p version which it doesn't exist apparently.

So, you need this to download and decrypt :

• chrome + tampermonkey + script to get the PSSH
• convert and reduce HEX (with https://base64.guru/converter for example)
• https://cdrm-project.com or equivalent
• yt-dlp
• mp4decrypt

How do you find the license URL?

[mohegan]

How do you find the license URL?

Just play the video and search "widevine" on the developper tools / network tab !

For example :
For https://vod.tvp.pl/programy,88/kolo-fortuny-odcinki,273642/odcinek-1591,S01E1591,389156 the licence url is :
https://vod.tvp.pl/api/products/389156/drm/widevine?platform=BROWSER&type=MOVIE
