Hi there, can the script be adapted to make it work for primevideo.com?

[DevLARLEY]

Not yet because my vpn is being detected

I just modified the resource_url, the cookie_names (adding -av at "ubid-main-av", "x-main-av", "at-main-av" for the .com tld, which is primevideo.com in reality). I've also modified the lic_url: "https://atv-ps-eu.primevideo.com...". I've run the script, added the asin, cdm is in order and working (tested in wks-keys). For the ASIN amzn1.dv.gti.d1f8ecd4-fcc3-4d1b-a929-90dcb8f5bd47 I get the following error as in the following image.

The headers are as follows:

amazon uk cookies = { 'ubid-acbuk': '', 'x-acbuk': '', 'at-acbuk': '' }

amazon de cookies = { 'ubid-acbde': '', 'x-acbde': '', 'at-acbde': '' }

primevideo.com cookies = { 'ubid-main-av': '262-3083430-2068635', 'x-main-av': '8w31Nqtyuq1q3ckdJJBdGIOxR5AqGgXw', 'at-main-av': 'Atza|IwEBIM4fiYForBBRBZKpcZpGv0bH7Xg82crV7CHGwQIhTVKUnLbEly8zzVPJpB7nT-6YD7pE2OtejpC7OKksWTrsMFzlQ6cIGB660-9Po-IksQXK7b9FSQYoLCSbDtmIICygLPJzgQEyLaMDTuR2WpPM0imfjnvUnZ2Lr1mdxUBC80WT4-TMaBoVOEoOYPsXAm5rzREp4sGX133YAWuIXkdsWmT8jdhUCqGIY8CPrsv01-rxiO1xSO0MLxixJrXoyVSGPRM' }

What I don't understand is: with an L3 cdm one can download a 1080p video, but the script is parsing an mpd which limits the resolution to 480p max. Why?

[DevLARLEY]

Are you logged into primevideo on firefox?

[RacketWise]

Are you logged into primevideo on firefox?

yes

[DevLARLEY]

Regarding your post edit: Theoretically, any resolution can be downloaded with an L3 CDM, it's up to the streaming provider to decide what level of quality they want to offer for each 'security level'. Amazon chose to only make 480p available to a normal L3 CDM. Higher resolutions require either VMP validation or an L1 CDM. Google actually has recommendations on exactly this kind of quality/security balancing.

Ok, but why the script is returning me a GeoIP error?

[DevLARLEY]

GeoIP generally indicates geoblocking and, if you're using a VPN, that's probably going to be the cause of this error. But i think i've had this issue in some other case before, i think it was related to incorrect cookies but i'm not sure.

[RacketWise]

I'm not using a VPN. I managed also to get the script to work by changing the cdm but now I've got another problem. The parsed mpd is pulling only GB audio and not IT. In Firefox and on primevideo.com I'm on IT language when I get all the cookies and asin code... Same story also under Chrome.

[RacketWise]

Is there a way to pull the IT language also in the mpd?

[DevLARLEY]

I'm on vacation. I'll get back to you.

[DevLARLEY]

Could you post the MPD file/URL?

[DevLARLEY]

I need the MPD URL, as i don't have primevideo right now. The script should output it on runtime.

How did you extract the mpd? This one has IT audio... How did you do that?

[antoniantonio791]

I'm a subscriber of italian prime,so the italian audio. By the way RacketWise too have italian prime,so i joined to the thread.

[RacketWise]

I'm a subcriper of italian prime,so the italian audio.

The issue is concerned obtain license,hope for fix me too.

I can't fix it since i can't reproduce the error because i can't use my VPN to acces the site
