VLC 媒体播放器是包括^{(VLC Media Player)}Windows和Linux在内的大多数平台上流行的媒体播放器之一。由于能够播放^(Being)蓝光^(Blu-ray)光盘中的媒体，许多人倾向于使用它。但是很多人一直在报告一个错误，上面写着-

Blu-ray error:

This Blu-ray Disc Needs a Library for AACS Decoding, and your system does not have it.

Your input can’t be opened:

VLC is unable to open MRL ‘blueray://J::/’. Check the log for details.

今天，我们将尝试解决这个问题。

此蓝光光盘^(Disc)需要用于AACS解码的库

有两种情况可以触发此错误。他们是-

• 蓝光光盘受到AACS和 BD+ 技术的保护。
• KeyFB.cfg 文件丢失。

两者的修复都需要执行相同的步骤。

首先^(First)，您需要检查Windows的体系结构和VLC是否安装在您的计算机上。这会很有帮助。

现在，在这里^(here)访问这个第三方网站。无论您的系统^(System)和VLC架构如何，您都需要获取相同的 密钥数据库 ( ^{(Keys Database ()}KEYDb.cfg )文件。

您需要的另一个文件是 AACS 动态库 ( ^{(AACS Dynamic Library ()}libaacs.dll )文件。这取决于您安装的VLC 媒体播放器的体系结构。^{(VLC Media Player)}

现在，您需要将下载的第一个密钥数据库^{(Keys Database)}文件复制到AppData 文件夹^{(AppData Folder)}。

为此， 请按键盘上的WINKEY + R 

现在，输入 %APPDATA%\ 并按 Enter。

在文件资源管理器^{(File Explorer)}中打开的位置创建一个文件夹，并将其命名为 aacs 。

将KEYDB.cfg ^{(KEYDB.cfg )}文件粘贴 到此文件夹中。

现在，获取您下载的AACS 动态文件^{(AACS Dynamic File)}。

如果您在 x64 版本的Windows上使用 x86 版本的^(Windows)VLC 媒体播放器^{(VLC Media Player)}，只需导航到以下位置，

C:\Program Files (x86)\VideoLAN\VLC

如果您在 x64 版本的Windows上使用 x64 版本的^(Windows)VLC Media Player，或在 x86 版本的Windows上使用 x86 版本的^(Windows)VLC Media Player，只需导航到以下位置，

C:\Program Files\VideoLAN\VLC

最后，将动态库^{(Dynamic Library)}文件 libaacs.dll粘贴到此位置。

立即打开VLC 媒体播放器^{(VLC Media Player)}，如果错误已修复，请单击。

注意^(Note)：下载上面给定文件的链接会引发错误，指出该网站的SSL 证书^{(SSL Certificate)}无效。您只能在本网站上忽略它，因为没有报告关于它的恶意活动。

VLC Media Рlayer is one of the popυlar media players on most of the platforms including Windows and Linux. Being capable of playing mediа from the Blu-ray disks, many people tend to use it for the same. But many people have been reporting an error that ѕays-

Blu-ray error:

This Blu-ray Disc Needs a Library for AACS Decoding, and your system does not have it.

Today, we will try to fix this issue.

This Blu-ray Disc needs a library for AACS decoding

There are two scenarios that can trigger this error. They are-

• Blu-ray disks are being protected by AACS and BD+ technologies.
• The KeyFB.cfg file is missing.

The fix for both of them requires the same steps to be undertaken.

First of all, you need to check the architecture of Windows and VLC is installed on your computer. It will be helpful.

Now, visit this third-party website here. You need to get the Keys Database (KEYDb.cfg) file which is the same, irrespective of your System and VLC architecture.

The other file that you need is the AACS Dynamic Library (libaacs.dll) file. This depends on the architecture of VLC Media Player that you have installed.

Now, you need to copy the first Keys Database file that you downloaded to the AppData Folder.

For that, hit the WINKEY + R button combination on your keyboard.

Now, type in %APPDATA%\ and hit Enter.

Create a folder in the location opened in the File Explorer and name it as aacs.

Paste the KEYDB.cfg file inside this folder.

Now, get the AACS Dynamic File that you downloaded.

If you are using an x86 version of VLC Media Player on an x64 version of Windows, just navigate to the following location,

C:\Program Files (x86)\VideoLAN\VLC

If you are using an x64 version of VLC Media Player on an x64 version of Windows, or x86 version of VLC Media Player on an x86 version of Windows, just navigate to the following location,

C:\Program Files\VideoLAN\VLC

Finally, paste the Dynamic Library file libaacs.dll into this location.

Open VLC Media Player now and click if the error has been fixed.
