直到教程-3，它都没有任何问题。问题来自4，我认为这可能是由于gnutls和openssl的更改导致的错误。如果我将Android.mk中的G_IO_MODULES更改为gnutls，它就会构建，但一旦运行就会结束，并出现以下错误。"FORTIFY:%n在Android上不允许"；

"；FORTIFY:%n在Android上不允许">
因此，如果我修改原始的G_IO_MODULES:=openssl，它将无法执行，并出现以下错误。实际上，该路径中没有文件，只有libgiogutls.a。我该如何正常操作？我检查了名为cebero的部分中的错误，但我不知道如何修复它，也不知道如何在Android中修复它。

我的猜测是，您正在混合不同版本的gst-examples/gst-docs存储库和下载的GStreamer二进制文件。如果您下载了最新的稳定的GStreamer二进制文件(在撰写本文时为1.16.2(，那么您应该从gst-examples和gst-docs的1.16分支构建匹配的文件。
GStreamer master已经转移到openssl而不是gnutls，以满足其所有ssl需求，gst示例和gst-docs教程已经更新，将与1.16版本的GStreamer不兼容。
对于"；FORTIFY:%n在Android上不允许"；看看这个上游问题：https://gitlab.freedesktop.org/gstreamer/cerbero/-/issues/146请确保您的构建版本至少为1.16.1，并且您已经对应用程序进行了从头开始的构建，删除了所有*.o和*.so文件。
