我正在尝试测试Android Gstreamer。 所以我安装并配置了路径SDK，获得了tutorial source，在教程的Android.mk中修改了路径，并在android-tutorial-1 / jni中进行了ndk-build。 但我得到了
$ ndk-build

GStreamer : [COMPILE] => gst-build-arm64-v8a/gstreamer_android.c

答案 0 :(得分：3)
您使用的教程实际上并非来自GStreamer，而是来自第三方，现在已经很老了。我还没有能够使用Android Studio，只有Eclipse。如果您想使用最新的Android GStreamer，我建议您查看this Github project。
它应该可以直接使用GStreamer SDK 1.8.0或更高版本。您需要的唯一更改是在build.gradle文件中，在getNdkCommandLine(ndkRoot, target)方法中将gstRoot变量设置为GStreamer SDK的路径。

请参阅gstreamer-devel，您可能错过了Android更新
