程序成功编译并显示以下输出：
在rtsp://127.0.0.1:8554/测试时准备流
当我打开VLC并提供上述流链接时，程序显示以下错误：
**（GStreamer_FirstApp.exe:1836）：警告**：未能创建元素“rtpbin”，
检查您的安装
我在网上搜索这个问题的解决方案，但还没有成功。任何帮助解决这个问题的人都将不胜感激。
最佳答案
看起来您还没有安装包含rtpbin元素的rtpmanager插件（它也是gst插件good的一部分）。
似乎也有类似的问题：http://gstreamer-devel.966125.n4.nabble.com/rtpbin-issue-using-gst-rtsp-server-1-0-on-Android-td4669600.html
关于c - 无法创建元素“rtpbin”，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/30911127/
