I\'m using Ubuntu 11.04 and Eclipse. I installed Xuggler succesfully, I\'ve checked the environment variables and everything related with linux in their FAQ: http://wiki.xug
Cause Could be un-availability of dependency jars or version conflicts.
Adding the following jars in the classpath worked fine for me:
xuggle-xuggler-5.4.jar
slf4j-api-1.6.4.jar
logback-core-1.0.0.jar
logback-classic-1.0.0.jar
Note: Add them in the library folder using "Add jar/Folder" Option in netbeans.
