当我运行这行代码时

  MovieCreator.build("mnt/sdcard/CamVideo/0.mp4")

应用程序崩溃并且崩溃日志是

我正在使用示例代码中的相同属性文件＆＃34; isoparser-custom.properties＆＃34;和＆＃34; isoparser-default.properties＆＃34;

我期待电影对象应该正确构建。任何人都可以告诉我在这方面做错了什么，或者可以向我发送合并两个mp4文件的完整功能代码。

编辑： 我下载了这个文件＆＃34; isoparser-1.0.2.jar＆＃34;来自maven项目（http://repo1.maven.org/maven2/com/googlecode/mp4parser/isoparser/1.0.2/），但应用程序崩溃了这个崩溃报告

当你自己构建mp4parser时，你没有调用aspectJ编译器/编译时编织。请使用预编译版本 - 它们在maven central上可用 - 或确保您调用编译时编织。

Sonatype OSS staging repositories中提供了比Maven Central更新的版本。在存储库选项卡的标题中，请选择“Nexus Managed Repositories”（而不是User Managed Repositories）并搜索mp4parser。

如果您不使用maven或gradle等依赖关系管理工具，请确保包含AspectJ runtime jar（目前版本1.8.0）。
