我刚刚开始使用 Xuggle，我将所有内容下载到 Eclipse 中，并将它们包含在引用库中，但我做了一个非常简单的测试，

package com.xuggle.xuggler.demos;
import com.xuggle.xuggler.IContainer;

public class getContainerInfo {
public static void main (String [] args){

     IContainer myContainer = IContainer.make();
    }
}

它会抛出一堆错误，

最佳答案

下面是我找到的。这是因为从 Xuggler 5.2 及更高版本开始，您不需要安装它并设置环境变量。

在网上寻找答案时，您可能会发现混合了新旧版本的步骤，这让您感到困惑。下面 (B) 中的步骤不再适用。

我自己最终通过确保 jar 在 J2EE 容器库中并将 Xuggler 5.2 升级到 5.4 来解决问题。此后，链接错误消失了。

(A) 这适用于所有版本
来自the Xuggler Docs :

Using Xuggler with J2EE Containers
Xuggler contains Native Code and therefore requires special installation with J2EE containers such as Tomcat, Jetty or Glassfish. It must be installed in a location where the J2EE container loads it, rather than a specific web application (unless you can guarantee that your application is the only application in the server that will load Xuggler). You will have to look up the specific documentation for your specific container, but as an example, for Tomcat make sure you install xuggle-xuggler.jar file to $CATALINA_HOME/shared/lib. See tomcat JNI notes for the reason why.

(B) 这仅适用于 XUGGLER PRE 5.2
来自:Xuggler Faq :

What's up with java.lang.UnsatisfiedLinkError?
It means that Java can't find the Xuggler native library. Check the following:
Did you install the Xuggler?
If not, follow the instructions here

• Is the environment variable XUGGLE_HOME defined and pointing to your Xuggler install directory (usually C:\Program Files\Xuggle on Windows or /usr/local on Linux/Mac)?
• If you installed on Windows, did you reboot after you installed? Does your PATH environment variable include %XUGGLE_HOME%\bin on Windows or $XUGGLE_HOME/bin on Linux/Mac?
• Does your PATH environment variable include %XUGGLE_HOME%\lib on Windows?
• Does your LD_LIBRARY_PATH environment variable include $XUGGLE_HOME/lib on Linux?
• Does your DYLD_LIBRARY_PATH environmentvariable include $XUGGLE_HOME/lib on Mac OS-X?
• Are you using a 32-bit Java JVM, but a 64-bit version of Xuggler? Or a 64-bit version of the Java JVM but a 32-bit version of Xuggler? Unfortunately that won't work. You need to make sure that you match the "bitness" of each release. Sorry. If fixing those problems doesn't resolve the issue, please contact us via the Support options.
