使用 Gstreamer 时在 Android 中出现 "Unacceptable TLS cerificate" 错误
Getting "Unacceptable TLS cerificate" error in Android when using Gstreamer
我目前使用 GStreamer 设置我的项目，我想流式传输 RTSP link。在将 GStreamer 与我的项目集成之前，我阅读了 [此处][1] 中提到的教程，并使用我自己的 rtsp link 测试了媒体 uri。有效！但它无法在我的项目上工作。有什么我应该寻找的吗？
-项目指向最新的gstreamer库
-项目也是指向最尖的ndk build
-C 代码运行良好，因为我能够看到提供的日志。

找到答案了！显然我的 ssl 证书文件夹位于错误的资产目录文件夹 src/assets/ssl/certs/ca-certificates.crt 中，它应该位于 src/main/assets 文件夹中。愚蠢的错误，但我希望这可以帮助其他人！
