下载gstreamer-android libs

下载gstreamer-1.0-android-universal-1.19.3解压到/home/hui/disk4t/codes/gstreamer-gstplayer/gstreamer/gstreamer-1.0-android-universal-1.19.3，前面gstAndroidRoot用的地址就是这个目录

下载地址：

https://gstreamer.freedesktop.org/data/pkg/android/1.19.3/gstreamer-1.0-android-universal-1.19.3.tar.xz

import到android studio后编译OK。

使用官网cerbero提供的编译方式也可以生成gstreamer-1.0-android-universal-1.19.3.tar.xz
