MIUI version is irrelevant. Each build has to be certified individually, so some Stable ROMs might not be certified (usually called "Stable Beta"), but for Weeklies we use a known certified fingerprint in order to pass SafetyNet.

robertb_45 said:

... (Google provides Widevine certificates) ...

Click to expand...

Absolutely false. Widevine L1 certificates are provisioned by Xiaomi Could service (com.miui.cloudservice) which sends a request to a Xiaomi-owned server (find.api.micloud.xiaomi.net). That service also handles certificates for supported payment services, like FIDO and IFAA/Alipay.
Widevine L1 certificate provisioning has absolutely nothing to do with Google in MIUI's case.

robertb_45 said:

... the Xiaomi.eu team has to wait untill the device or MIUI version gets released Globaly by Xiaomi, and that's where they get certificates.

Click to expand...

Not true. A Stable China ROM can get certified even if the device is not available Globally, that depends on whether the China ROM for that device comes with pre-included super-basic Google Play services configured for China (which is the case for many high-end Xiaomi devices).
In short, as long as it's an actual "Stable", and not "Stable Beta", China ROM, then it usually gets certified, even if with a delay.

Widevine digital rights management explained

A number of video services like Google Play Movies, Netflix, and Amazon Prime Video don’t allow some smartphones to stream movies or TV shows at resolutions higher than 480p. The reason for the lockout is that these services are protected by digital rights management (DRM), to prevent the copying and unauthorized redistribution of these video files.

To trust that Android smartphone and many other devices are secure from piracy, these popular streaming services make use of Google’s Widevine DRM platform. As one of the industry’s oldest DRM services, it’s estimated to be installed on some 4 billion devices around the world.

Here’s what you need to know about Widevine and how it works.

How does Widevine work?

Widevine implements a selection of industry standards to protect content as it’s transferred over the internet and played back on devices. For a quick overview, it makes use of a combination of CENC encryption, licensing key exchange, and adaptive streaming quality to manage and send video to users. The idea is to simplify the amount of work on the service provider’s end, by supporting multiple levels of streaming quality based on the security capabilities of the receiving device.

To achieve this, Widevine protects content across three levels of security, simply named L3, L2, and L1. Your device will need to be certified to meet the full L1 specification if you want to stream HD content from services like Netflix.

TrustZone technology within Cortex-A based application processors is commonly used to run trusted boot and a trusted OS to create a Trusted Execution Environment (TEE), which separates DRM and other processing from potentially exploitable applications.

ARMTrustZone technology within Cortex-A based application processors is commonly used to run trusted boot and a trusted OS to create a Trusted Execution Environment (TEE), which separates DRM and other processes from potentially exploitable applications.

To meet security Level 1, all content processing, cryptography, and control must be performed within the Trusted Execution Environment (TEE) of the device’s processor, to prevent external tampering and copying of the media file. All ARM Cortex-A processors implement TrustZone technology, creating a hardware separation that allows a trusted OS (such as Android) to create a TEE for DRM, and other secure applications.

Security Level 2 only requires that cryptography, but not video processing, be carried out inside the TEE. L3 applies either when the device doesn’t have a TEE or when processing is done outside of it. However, appropriate measures must still be taken to protect cryptography within the host operating system.

How Widevine is implemented

Android devices support either L1 or L3 security levels, depending on hardware and software implementations, as does Chrome OS. Chrome on desktops will only ever support L3 at maximum. If your device is only L3-compliant, you’re capped at sub-HD resolutions. Only L1 secure devices with processing taking place entirely in the TEE can play back HD or higher quality content from Widevine secured services.

Perhaps one of the most important points to note about Widevine is that it doesn’t charge a license fee in order to implement its protection technology. So there’s no financial reason why some smartphones are missing out.

Instead, hardware manufacturers only need to pass a certification process. This includes the completion of various legal agreements, implementation of some software libraries, and client integration testing to verify support, among other steps. Apparently, this process is designed to be streamlined for easy adoption, and all chipsets used for Android smartphones support the necessary technologies, so it’s only likely that manufacturer oversight or lack of testing time is to blame if smartphones aren’t compatible. Fortunately, it seems that it’s possible for smartphone OEMs to address any lack of compliance after release. 

In January 2019, Security researcher David Buchanan claimed on Twitter that he managed to break the DRM on Widevine L3. It’s not clear if he has disclosed this reported issue to Google, and there’s been no word from the company on if it has fixed this DRM flaw.

Can my device stream HD content?

Unfortunately, you won’t find information about DRM conformity on many specification sheets, so knowing before purchasing a new phone is difficult. Most smartphones, especially in the flagship tier, will allow for HD streaming from Widevine powered services, even if the smartphone is a few generations old. Technically, all Android smartphones can support L1 Widevine security, but implementation mileage may vary with lower cost smartphones that may skimp on testing times.

If you want to check that your particular handset is compatible with Winevine, along with other popular DRM services, you can check out your smartphone’s level of support with apps like DRM Info, which is free to download from the Play Store. Simply scroll down to the Google Widevine DRM section and check what Security Level your device supports, just like in the image above.

Download DRM Info

In addition, Netflix has posted a constantly updated list of Android smartphones and tablets that are able to stream its movies and TV shows in HD resolution. The list also includes the chipsets from Qualcomm and Huawei that are capable of streaming Netflix videos in HD.

You'll lose HD Netflix on the OnePlus 7 Pro if you unlock the bootloader

By Ryne Hager

ShareTweetEmail

It's a bit of a bummer that the OnePlus 7 is only able to stream Netflix at "HD" resolution — that's below the full 1440p resolution of its beautiful display, after all. But if you decide to unlock the bootloader for future root/ROM adventures, then you'll have to make do with just non-HD 480p Netflix streams.

For the unfamiliar, Netflix and some other services like Hulu and Amazon Video use a Google-provided DRM solution called Widevine, which has multiple levels of security. A higher "L1" level of Widevine is required by Netflix for 720p HD playback. For a while, OnePlus phones didn't even support L1, though all phones since the OnePlus 6 have shipped with it. And like its predecessors, the OnePlus 7 Pro loses that L1 support if the bootloader is unlocked. In such cases, the devices fall back to (insecure) Widevine L3, which Netflix only uses for lower-quality 480p playback.

Not all devices lose Widevine L1 when the bootloader is unlocked — for example, the Pixel 3 XL last year — but OnePlus devices do, and based on reports, the 7 Pro is no exception.

UPDATE: 2019/05/30 7:30pm PDT BY RYNE HAGER

A previous version of this article referenced a 720p limit, as measured by certain videos in the Netflix catalog which show their output resolution in the video itself. We spoke to a representative from Netflix about this and were told that resolution varies based on encoding, with some titles in certain encodings not available at higher resolutions (specifically, this pertains to VP9 encoded content). The performance of such videos is not representative of the rest of Netflix's catalog or capabilities, which offers up to 1080p on capable devices, including the OnePlus 7 Pro.

Root widevine l1

Bootloader Unlocking removes OnePlus 7 Pro Widevine L1 certification

Android enthusiasts are very familiar with the bootloader unlocking process. It’s the genesis of every process of further customizing a smartphone since it’s the very first requirement in order to flash a custom recovery and subsequently a custom ROM. If you love to root and Custom ROMs, the bootloader unlocking process is always a path that you cross, no matter the consequences. The OnePlus 7 Pro recently gained root thanks to the bootloader unlocking and a custom recovery. That was the first step to new development and while users are pretty happy with it, they’re unaware of unavailability of Widevine L1 certification after the bootloader unlocking process.

OnePlus 7 Pro

Widevine is a digital rights management component used by Android MediaDRM and Chrome Web Browser to ensure security for video content being displayed in the screen. Various streaming platforms such as Netflix, Amazon Prime, and other networks use this certification to stream the best quality, without it device are unable to display HDR content. Devices with Widevine L1 certification can run the highest quality of video streaming available, while Widevine L3 limits it to 480p or lowest video quality. It further enhances content protection and video playback ensuring device security.

The same situation that happened with the OnePlus 6 and 6T is now plaguing OnePlus 7 Pro owners that unlocked the bootloader. Apparently, this act instantly makes the device Widevine L3 certified. Reports in the XDA-Developers forum emerged with users sharing the inability to watch high-quality video content from premium video streaming services. It is unclear whether relocking the bootloader fix the problem in the 7 Pro or not, however, this worked with the OnePlus 6 and 6T. Other devices such as Poco F1 are also plagued by weird behavior.

That’s just another caveat for those wishing to open the doors for custom ROMs.
