我最近开始帮助一位同事调试她的 Java Swing 应用程序的视频崩溃问题。该应用程序对 fobs4jmf.dll 进行 native 调用以播放 .avi 文件。有时，并非总是如此， native 代码会使应用程序崩溃。我没有编写原始应用程序，而编写的工程师早已不在；谁能提供一些见解？错误文件如下:
#

显然，当她的系统从 Windows XP 迁移到 Windows 7 时，该错误首先出现(您可能会开始默默诅咒并与各地的 IT 部门握手)；但是将机器恢复到 Windows XP 并不能解决问题。
同样值得重申的是，此错误并不总是发生!有时应用程序运行良好，有时在启动 native JMF 代码时会崩溃。
谢谢你的帮助!

此类错误一般在系统不支持dll文件时出现，请尝试检查
对应播放器的 dll 支持或
下载任何在您的系统中填充必要 dll 文件的应用程序尝试
