Macos 使用Mac OS X应用程序部署GStreamer框架的最佳方法？

因此，1.0+的GStreamer文档似乎……至少缺少一点。gstreamersdk有一些功能，但遗憾的是它们没有达到要求

这就是我所做的。我在/Library/GStreamer.Framework/

我使用命令行工具构建。这是我构建此应用程序的唯一方法。我不能使用XCode GUI

我想将此应用程序提交到应用商店，但为此，我无法将其作为包提交（因此我可以捆绑GStreamer包安装程序），这意味着我必须将GStreamer.framework与我的应用程序捆绑在一起

在上面的GStreamer SDK文档中，您会注意到一个名为osxrelocator.py的工具。这很好，因为它将/Library/GStreamer.Framework的所有引用更改为@executable\u path/./Frameworks/GStreamer.Framework/

但是

不幸的是，所有的GStreamer.dylibs都有一个问题。。。您需要使用install\u name\u tool-id来更改它们的路径，因为install\u name\u tool-change不会更改它们自己的路径

例如，使用耳石：

$ otool -L Application.app/Contents/Frameworks/GStreamer.framework/Versions/1.0/lib/libgstreamer-1.0.0.dylib
Application.app/Contents/Frameworks/GStreamer.framework/Versions/1.0/lib/libgstreamer-1.0.0.dylib:
    Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libgstreamer-1.0.0.dylib (compatibility version 402.0.0, current version 402.0.0)
    Library/Frameworks/Frameworks/GStreamer.framework/Versions/1.0/lib/libgobject-2.0.0.dylib (compatibility version 4001.0.0, current version 4001.0.0)
    Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libffi.6.dylib (compatibility version 7.0.0, current version 7.1.0)
    Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libgmodule-2.0.0.dylib (compatibility version 4001.0.0, current version 4001.0.0)
    Library/Frameworks/Frameworks/GStreamer.framework/Versions/1.0/lib/libglib-2.0.0.dylib (compatibility version 4001.0.0, current version 4001.0.0)
    Library/Frameworks/Frameworks/GStreamer.framework/Versions/1.0/lib/libintl.8.dylib (compatibility version 10.0.0, current version 10.2.0)
    Library/Frameworks/Frameworks/GStreamer.framework/Versions/1.0/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.1.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1197.1.1)
    /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 855.14.0)

然后使用osxrelocator.py（调用install\u name\u tool-change）：

给出：

$ otool -L Application.app/Contents/Frameworks/GStreamer.framework/Versions/1.0/lib/libgstreamer-1.0.0.dylib
Application.app/Contents/Frameworks/GStreamer.framework/Versions/1.0/lib/libgstreamer-1.0.0.dylib:
    /Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libgstreamer-1.0.0.dylib (compatibility version 402.0.0, current version 402.0.0)
    @executable_path/../Frameworks/GStreamer.framework/Versions/1.0/lib/libgobject-2.0.0.dylib (compatibility version 4001.0.0, current version 4001.0.0)
    @executable_path/../Frameworks/GStreamer.framework/Versions/1.0/lib/libffi.6.dylib (compatibility version 7.0.0, current version 7.1.0)
    @executable_path/../Frameworks/GStreamer.framework/Versions/1.0/lib/libgmodule-2.0.0.dylib (compatibility version 4001.0.0, current version 4001.0.0)
    @executable_path/../Frameworks/GStreamer.framework/Versions/1.0/lib/libglib-2.0.0.dylib (compatibility version 4001.0.0, current version 4001.0.0)
    @executable_path/../Frameworks/GStreamer.framework/Versions/1.0/lib/libintl.8.dylib (compatibility version 10.0.0, current version 10.2.0)
    @executable_path/../Frameworks/GStreamer.framework/Versions/1.0/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.1.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1197.1.1)
    /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 855.14.0)

注意.dylib引用自身的第一行吗？除非调用install\u name\u tool-id，否则不会更改为@executable\u path/。/Frameworks/GStreamer.framework/。GStreamer框架中的每个.dylib都会发生这种情况！有数百个，我相信手动操作肯定会导致错误

希望我已经把我的问题说清楚了。有人对该怎么做有什么建议吗

谢谢

我创建了一个简单的Xcode项目，向您展示如何捆绑框架：

---

图书馆搬迁用途：

---

使用XCode生成项目的安装程序：

• 安装gstreamer-1.0-1.5.2-x86_64.pkg
• 安装gstreamer-1.0-devel-1.5.2-x86_64.pkg
• 将/Library/Frameworks/GStreamer.framework移动到$（PROJECT_DIR）/GStreamer-devel.framework
• 转到$（PROJECT_DIR）并运行以下命令：

• osxrelocator./GStreamer-devel.framework/Versions/Current/Library/Frameworks/GStreamer.framework/

  pwd

  /GStreamer-devel.framework/

• install\u name\u tool-id@executable\u path/。/Frameworks/GStreamer.framework/GStreamer./GStreamer-devel.framework/Versions/Current/GStreamer

• 将“$（项目目录）/GStreamer-devel.framework/Headers”添加到头搜索路径
• 将“GStreamer-devel.framework/GStreamer”文件添加到Xcode项目中

---

准备运行时框架：

• 安装gstreamer-1.0-1.5.2-x86_64.pkg
• 将/Library/Frameworks/GStreamer.framework移动到$（PROJECT_DIR）/GStreamer.framework
• 对框架进行一些清理：

• rm./GStreamer.framework/Headers./GStreamer.framework/Commands

• rm./GStreamer.framework/Versions/Current/Commands

• rm-r./GStreamer.framework/Versions/Current/bin/

• rm-r./GStreamer.framework/Versions/Current/etc/

• rm-r./GStreamer.framework/Versions/Current/share/

• 重新定位框架的.dylibs：

• osxrelocator-r./GStreamer.framework/Versions/Current/Library/Frameworks/GStreamer.framework/@executable\u path/./Frameworks/GStreamer.framework/

• 由于gst插件扫描程序在gst_init期间执行，因此它还必须能够找到所有库。 因此，在libexec目录中创建指向“Frameworks”的链接，以解析@executable\u path/。/Frameworks/GStreamer.framework/

• ln-sf../../../../GStreamer.framework/Versions/Current/libexec/Frameworks

• 在项目的构建阶段设置中，创建新的复制文件阶段并将GStreamer.framework复制到Fameworks

---

在调用GST_init（）之前，在代码中设置GST_PLUGIN_SCANNER和GST_PLUGIN_SYSTEM_PATH环境变量：

---

我想可能是静态链接文件？这带来了以下问题：我使用ldflags链接：-F/Library/Frameworks-framework-GStreamer，似乎没有一种静态链接框架的方法？
