GStreamer 1.18.4 Ubuntu 20.04上未定义符号gst\U rtcp\U buffer\U add\U数据包

我正在开发一个定制的GStreamer插件。最初，我是在macOS机器上开发的，它在那里工作得很好。然而，当我在Ubuntu20.04机器上编译插件时，当我尝试检查插件中的元素时，会出现一个运行时错误，如下所示：

gst-inspect-1.0 lib/umake/gcc-9.3/x86_64/release/libgststream.so

错误：

我在Ubuntu上安装了GStreamer 1.18.4，还尝试重新安装了所有东西

我不明白为什么符号

gst\u rtcp\u buffer\u add\u packet

似乎没有定义。此方法位于gst插件库中，该库默认使用gst构建中的介子构建进行安装。我有什么遗漏吗

以下是ldd-r lib/umake/gcc-9.3/x86_64/release/libgststream.so中的共享对象依赖项：

编辑：我还添加了输出：

GST\u REGISTRY=/tmp GST\u DEBUG=4 GST\u DEBUG\u FILE=gstreamer.log GST-inspect-1.0 lib/umake/gcc-9.3/x86\u 64/release/libgststream.so

。不过，我在这里没有发现任何异常。

结果是，由于我的CMakelists.txt文件中缺少RTP依赖项，因此找不到符号。添加组件Rtp后，现在可以找到插件元素

find_包（GStreamer模块所需组件视频音频Rtp）
