gstreamer及相关插件编译完成后，会输出gst-inspect可执行文件，相关信息如下：
drwxrwxr-x 12 yingc yingc 4096 6月 15 16:56 glib-2.42.0/ drwxrwxr-x 10 yingc yingc 4096 6月 15 17:05 gst-libav-1.4.5/ drwxrwxr-x 14 yingc yingc 4096 6月 15 17:03 gst-plugins-bad-1.4.5/ drwxrwxr-x 14 yingc yingc 4096 6月 15 16:59 gst-plugins-base-1.4.5/ drwxrwxr-x 13 yingc yingc 4096 6月 15 17:00 gst-plugins-good-1.4.5/ drwxrwxr-x 13 yingc yingc 4096 6月 15 17:01 gst-plugins-ugly-1.4.5/ drwxrwxr-x 14 yingc yingc 4096 6月 15 16:57 gstreamer-1.4.5/
./gst-inspect-1.0 -h
用法：
gst-inspect-1.0 [选项...] [ELEMENT-NAME | PLUGIN-NAME]
帮助选项：
-h, --help 显示帮助选项
--help-all 显示全部帮助选项
--help-gst 显示 GStreamer 选项
应用程序选项：
-a, --print-all 打印全部组件
-b, --print-blacklist 显示黑名单文件列表
--print-plugin-auto-install-info 显示机器可解析的指定插件或所有插件提供的特性列表。
与外部自动插件安装机制连接时有用
--plugin 列出插件信息
--exists Check if the specified element or plugin exists
--atleast-version When checking if an element or plugin exists, also check that its version is at least the version specified
-u, --uri-handlers 打印所支持的 URI 样式及它们的关联组件
--version Print version information and exit
执行gst-inspect-1.0 --plugin，我们会看到当前gstreamer所有的可用插件等：
