具有TLS示例的GStreamer RTSP服务器示例失败

Question

我试图使用GStreamer 1.7.1启动具有身份验证和TLS支持的RTSP服务器。我使用的代码与file from source几乎相同，只有#define WITH_AUTH和#define WITH_TLS。

我在示例目录内编译后使用./test-video启动服务器。

要访问的流，我从同一台机器上使用终端以下行连接： gst-launch-1.0 rtspsrc location=rtsps://127.0.0.1:8554/test user-id=user user-pw=password tls-validation-flags=generic-error ! rtph264depay ! avdec_h264 ! videoconvert ! osxvideosink

当我试图启动客户端，服务器输出的消息：

我目前正在尝试OS X El Capitan机器，但我也有在Linux Mint 17.3盒子上试用并收到相同的消息。

有没有人对我如何解决这个问题有任何想法？感谢您提前提供任何帮助。

这些错误可能是由于gstreamer或glib无法动态加载模块。

先检查：

与任何TLS功能，油嘴动态加载TLS模块中。通过defualt这是一个gnutls模块。在Ubuntu上，这可在/usr/lib/x86_64-linux-gnu/gio/modules/libgiognutls.so中找到。如果你想自己编译，这个依赖是由glib-networking（https://github.com/GNOME/glib-networking）提供的。

第二次检查：

TLS握手完成后，RTSP服务器然后继续设置的SRTP通道。如果系统中不存在SRTP插件，程序将发布CRITICAL错误。运行gst-inspect-1.0 srtpenc和gst-inspect-1.0 srtpdec验证这些插件是否存在并且它们的依赖关系是否满足。
