具有TLS示例的GStreamer RTSP服務器示例失敗

Question

我試圖使用GStreamer 1.7.1啓動具有身份驗證和TLS支持的RTSP服務器。我使用的代碼與file from source幾乎相同，只有#define WITH_AUTH和#define WITH_TLS。

我在示例目錄內編譯後使用./test-video啓動服務器。

要訪問的流，我從同一臺機器上使用終端以下行連接： 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

當我試圖啓動客戶端，服務器輸出的消息：

我目前正在嘗試OS X El Capitan機器，但我也有在Linux Mint 17.3盒子上試用並收到相同的消息。

有沒有人對我如何解決這個問題有任何想法？感謝您提前提供任何幫助。

這些錯誤可能是由於gstreamer或glib無法動態加載模塊。

先檢查：

與任何TLS功能，油嘴動態加載TLS模塊中。通過defualt這是一個gnutls模塊。在Ubuntu上，這可在/usr/lib/x86_64-linux-gnu/gio/modules/libgiognutls.so中找到。如果你想自己編譯，這個依賴是由glib-networking（https://github.com/GNOME/glib-networking）提供的。

第二次檢查：

TLS握手完成後，RTSP服務器然後繼續設置的SRTP通道。如果系統中不存在SRTP插件，程序將發佈CRITICAL錯誤。運行gst-inspect-1.0 srtpenc和gst-inspect-1.0 srtpdec驗證這些插件是否存在並且它們的依賴關係是否滿足。
