What to say at the beginning:
the core issue is the directory is wrong after compile VLC on Linux. Some .so files can not be correctly found and load.
So I just fix this issue to make sure Program can find .so files.
You don't need edit directory to be the same as me，but the core issue is the same.

1. Follow this guy's methodhttps://github.com/ue4plugins/VlcMedia/issues/17#issuecomment-348637265,but we just only need to do at the third step ,because there are some directory are wrong and some files UE4 program can not find and load them at runtime. After you have done the First three steps,continue to follow my method below .

2. Edit VlcMedia.Build.cs and Vlc.cpp files
   Vlc.cpp
   Before :
   #if PLATFORM_LINUX const FString LibDir = FPaths::Combine(*VlcDir, TEXT("Linux"),TEXT("x86_64-unknown-linux-gnu"), TEXT("lib"));
   After:
   #if PLATFORM_LINUX const FString LibDir = FPaths::Combine(*VlcDir, TEXT("Linux")/*TEXT("x86_64-unknown-linux-gnu")*/, TEXT("lib"));

   VlcMedia.Build.cs
   Before:
   if (Target.Platform == UnrealTargetPlatform.Linux) { VlcDirectory = Path.Combine(VlcDirectory, Target.Architecture,"lib"); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlc.so")); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlc.so.5")); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlc.so.5.6.0")); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlccore.so")); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlccore.so.9")); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlccore.so.9.0.0")); }
   After:
   if (Target.Platform == UnrealTargetPlatform.Linux) { VlcDirectory = Path.Combine(VlcDirectory, /*Target.Architecture*/"lib"); System.Console.WriteLine("VLCDirectory ============" + VlcDirectory);//to print lib file directory to make sure is correct RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlc.so")); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlc.so.5")); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlc.so.5.6.0")); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlccore.so")); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlccore.so.9")); RuntimeDependencies.Add(Path.Combine(VlcDirectory, "libvlccore.so.9.0.0")); }

3.Go to /yourProjetct/Plugins/VlcMedia/ThirdParty/vlc/Linux/
Create folder named "lib"
Go to /yourProjetct/Plugins/VlcMedia/ThirdParty/vlc/Linux/x86_64-unknown-linux-gnu
find "vlc" folder.Copy it to lib folder which we have just created.
Go to /yourProjetct/Plugins/VlcMedia/ThirdParty/vlc/Linux/x86_64-unknown-linux-gnu
Search these.so files and copy them to lib folder which we have just created.

•  libvlc.so
  

•  libvlc.so.5
  

•  libvlc.so.5.6.0
  

•  libvlccore.so
  

•  libvlccore.so.9
  

•  libvlccore.so.9.0.0
  

  If you don't have this folder and files ,check the first step ,make sure you have correctly link and compile vlc on Linux

4.Compile your Project . No other words,now is working fine at runtime .
