XUGGLE ERROR:线程"main"中的异常java.lang.NoClassDefFoundError:org/slf4j/LoggerFactory

Question

我正在尝试执行以下代码:

import com.xuggle.mediatool.IMediaReader;
import com.xuggle.mediatool.IMediaWriter;
import com.xuggle.mediatool.ToolFactory;
public class vidcon {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        IMediaReader reader = ToolFactory.makeReader("test.m4v");
        IMediaWriter writer = ToolFactory.makeWriter("out.flv");

        reader.addListener(writer);
        while(reader.readPacket() == null)
            ;
    }
}

但这是给我这个错误:

我已将SLF4J添加到我引用的库中,但不知道为什么这不起作用.

在WIN 7上运行,在eclipse和netbeans中尝试过

任何的想法？

Answer 1

下载SLF4J并将slf4j-api-1.7.2.jar文件放到类路径上.

Answer 2

以下罐子组合对我有用:

log4j-1.2.16.jar
slf4j-api-1.7.6.jar
slf4j-simple-1.7.6.jar
xuggle-xuggler-5.4.jar
