Macos Mac OSX上的VLCJ未满足链路错误（darwin/libvlc.dylib）

我正在尝试初始化VLCJ，以便作为我正在开发的应用程序的一部分进行一些流式处理。按照，我将使用以下代码尝试加载库：

NativeLibrary.addSearchPath(
    RuntimeUtil.getLibVlcLibraryName(), "/Applications/VLC/Contents/MacOS/lib"
    );
Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class);

当我运行它时，会出现以下错误：

Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'vlc': JNA native support (darwin/libvlc.dylib) not found in resource path (/Users/iamparker/Documents/workspace/VLCStreamer/target/classes:/usr/jar/vlc/vlcj-3.0.1-javadoc.jar:/usr/jar/vlc/vlcj-3.0.1-sources.jar:/usr/jar/vlc/vlcj-3.0.1-test-sources.jar:/usr/jar/vlc/vlcj-3.0.1-tests.jar:/usr/jar/vlc/vlcj-3.0.1.jar:/usr/jar/vlc/jna-4.1.0.jar:/usr/jar/vlc/jna-platform-4.1.0.jar)

原来这只是我一个愚蠢的错误。我给出的路径是

“/Applications/VLC/Contents/MacOS/lib”

，它应该是

“/Applications/VLC.app/Contents/MacOS/lib”

。我忘了VLC有一个.app扩展。我现在就去把脑袋埋在沙子里

cd src/main/resources/
cp -r /Applications/VLC.app/Contents/MacOS/lib darwin
rm darwin/*.*.*
cd darwin
install_name_tool -add_rpath @loader_path libvlc.dylib
mkdir vlc
cp -r /Applications/VLC.app/Contents/MacOS/plugins vlc/plugins

这是macOS版本。它对我有用。也许能帮你

我将vlcj maven依赖项更新为：

    <dependency>
        <groupId>uk.co.caprica</groupId>
        <artifactId>vlcj</artifactId>
        <version>3.12.1</version>
    </dependency>

英国卡布里卡公司
vlcj
3.12.1

它是有效的

您知道在该路径中有两组不同的JNA jar文件吗？您应该删除其中一个。不管怎样，哪个JDK，哪个VLC版本？最常见的问题是混合使用32位和64位。您还应该尝试运行vlcj“NativeDiscoveryTest”。我刚刚在OSX 10.9.2上试用过，效果很好。我也注意到了。我已经将4.1.0 JNA文件添加到了构建路径a中
