计算目录中 MP4 文件的总持续时间时出现 SLF4J 问题
Issue with SLF4J while calculating total duration of MP4 files in a directory
主要目标:
我的主要目标是从目录中获取所有 .mp4
文件的持续时间。所以,我用谷歌搜索并找到了 where one answer referred this 的完整代码。
导入错误:
当我在我的代码中获取必要的部分时,它在以下行中显示错误:
import com.xuggle.xuggler.IContainer;
之后,我从 here which I got from here 下载了 Xuggler。然后我得到以下错误:

解决异常 "SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder":
寻找它的解决方案,我得到了this question,接受的答案除了删除错误流中的前三行外什么也做不了。
当时我尝试过的:
我尝试在我的项目中添加以下 .jar
文件:
- xuggle-xuggler-5.4.jar
- slf4j-api-1.6.4.jar / slf4j-api-1.7.12.jar
- slf4j-simple-1.7.6.jar / slf4j-simple-1.7.12.jar
- log4j-1.2.16.jar
- logback-classic-1.0.0.jar
- logback-core-1.0.6.jar
- slf4j-jdk14-1.7.12.jar
- slf4j-log4j12-1.7.12.jar
文件 - hs_err_pid10112.log:
您可以看到错误文件 here,我无法添加它,因为添加它会超过字符数限制。
如何解决这个问题?
注:
我已经遍历了以下问题:
- using Logback with slf4j [on hold]
- Given I'm stuck with SLF4J and java.util.Logging, what is optimal solution?
- How do I get a list of configured loggers using Jboss LogManager with SLF4J?
- How to write event logs into xml files with SLF4J or Logback?
- OpenJPA logging with slf4j on WebSphere
- Tomcat Logging With Slf4j and Log4j
我会尝试一一添加您的依赖项(同时注释掉依赖代码)。我的第一印象是其中一个库在其类路径上具有与 slf4j 不兼容的 versions/backends 功能。在您发现这一点之前,您不可能知道是哪一个。一旦你这样做了,你可以gradle/maven从你的类路径中排除一个冲突的东西。
您通常需要三个功能部件:
- 程序使用的API(slf4j-api)
- 使记录器实现适应 SLF4J 的桥接代码API(例如 slf4j-log4j12)这个必须与您使用的记录器相匹配。
- 记录器实现(例如 log4j)
一些罐子覆盖不止一个部分,例如logback 涵盖第 2 和第 3 部分,因为它本身实现了 slf4j,或者如果您使用 java util 日志记录,则不需要显式添加第 3 部分(它在 Java 运行时)
您还必须使用匹配版本的 slf4j 组件,例如不要将 slf4j-api-1.6.4.jar 与 slf4j-log4j12-1.7.12.jar 混合使用。
查看slf4j documentation了解详情。
我无法解决问题,但我可以通过其他方式实现我的目标。
我用过IBM的工具包。
- 已从 here 下载 IBM 的 API。
在我的代码中添加了以下代码片段:
public long getDuration(File file) throws IOException {
PlayerControl playerControl = PlayerFactory.createLightweightMPEG4Player();
playerControl.open(file.getAbsolutePath());
return playerControl.getDuration();
}
因为我的目标只是获得持续时间,所以这不是有效的方法。
在我的 PC(core-i5、2.5GHz、6GB 内存、Win10)中,处理 60 个 .mp4
个文件花费了 42657ms
,这些文件输出了 大约 6 小时 41 分钟持续时间.
如果需要,可以在my repository中查看。
