Is there a way to download Dolby Digital Plus 5.1 audios from Hotstar ??

[KyoGo]

Using YT-DL it only shows AAC 2.0 channel audios but on Hotstar many of the titles support Dolby Digital Plus 5.1 audios .. I mean the .mpd file I got from network tab only shows AAC 2.0 audios .. so is there any hidden .mpd links that we cant see using normal browsers network tab ?? If anyone knows about how to get that hidden .mpd please guide me

General view of streaming:

- Videos (1080p at most) with 2.0 AAC sounds are protected by Widevine L3.

- Videos (1080p and above) with 5.1 DD+ sounds are protected with Widevine L1 or Playready. Computers cannot decrypt Widevine L1. That's for Android devices. For Playready-protected contents, you need a special graphics processor (Intel 7th Gen and above)

- Only a few exceptions (a few L3-protected 4K videos at a few sites)


So, even if you access MPD of L1-protected stream, you must have a L1-CDM and it is not easy to get one.

No way to decrypt Playready.

[Haft66]

so why you say playready you cant decrypt?

iam 100% sure that you can do it. Difficult but working. So i think playready are in TEE , too.

if not you can do it via hardware which playready enabled so you need only a correct script.


Its not public but i know some people can do it, so it work.

[ridibunda]

They decrypt L1, not Playready.

It's possible to emulate a L1-capable Android device. Never heard of emulating a Playready-capable device.

Some 5.1 DD+ sounds can be not-encrypted (like on NF). So it's just a matter of reaching them with extra scripts & add-ons (Dev Tools itself is not enough).

I'm also searching for a script to grab DD+ sounds (from another site), but unable to find it. A script cannot work on all sites, because each site design is different.

That's all I know.
