Fixing FFmpeg Can't Find Shared Library Issue on Asustor

Asustor is a popular Network Attached Storage (NAS) device that allows users to install various applications, including FFmpeg. FFmpeg is a powerful, open-source multimedia framework that can handle video and audio conversion, streaming, and playback. However, some users might encounter issues when trying to run FFmpeg on Asustor due to shared library dependencies.

Understanding Shared Libraries

In modern operating systems, applications often use shared libraries or dynamic link libraries (DLLs) to provide common functionalities. Shared libraries are pre-compiled, reusable code modules that can be loaded and linked to an executable during runtime. On Linux systems, such as Asustor, these libraries are typically stored in the /lib or /usr/lib directories.

FFmpeg Can't Find Shared Libraries

When running FFmpeg on Asustor, you might encounter an error similar to the following:

This error occurs because the FFmpeg binary is unable to find and load the required shared library (libx265.so.155 in this example). Let's discuss how to resolve this issue.

Solving the FFmpeg Shared Library Issue on Asustor

Here are the steps to fix the FFmpeg shared library issue on Asustor:

1. Identify the missing library: In the error message, look for the name of the missing library (libx265.so.155, in this example).

2. Locate the library: Use Asustor's Package Center to find and install the corresponding package that contains the missing library. In this case, you can search for the "libx265" package. Once you find it, make sure to install the package that provides the required library version.

3. Create a symbolic link: After installing the library package, the library file may still not be accessible to the FFmpeg binary. You may need to create a symbolic link to the library file in a directory where FFmpeg can find it, such as / volume1/.@plugins/AppCentral/ffmpeg/lib. To do so, follow these commands:

   ```bash cd /volume1/.@plugins/AppCentral/ffmpeg/lib ln -s /usr/lib/libx265.so.155 libx265.so.155 ```

4. Verify the library is accessible: Now, you can test if the FFmpeg binary can find the library. Run the following command:

   ```csharp /volume1/.@plugins/AppCentral/ffmpeg/bin/ffmpeg -version ```

   If the shared library issue is fixed, you should see the FFmpeg version information without any errors related to the library.

In this article, we discussed the issue of FFmpeg not being able to find its required shared libraries on Asustor. We highlighted the importance of shared libraries, walked through the steps needed to resolve the FFmpeg library issue, and provided a summary of the process.
