+## GStreamer
+
+GStreamer is a pipeline-based multimedia framework based on GObject and written in C. It is designed to be used with a wide variety of applications and applications. With GStreamer, it is easy to create a wide range of multimedia-capable components, including simple audio playback, audio and video playback, recording, streaming and audio editing. Based on the pipelined design , you can create many multimedia applications such as video editors , streaming media broadcasting and media players and so on .

+Next, a demo showing how to run GStreamer on LPi4A.
+First, you need to install the relevant dependencies:
+```shell
+sudo apt install git build-essential libgstreamer* gstreamer1.0-tools
+```
+
+Then pull the relevant source code repository
+```shell
+git clone https://gitlab.freedesktop.org/gstreamer/gst-docs
+```
+
+Go to the `gst-docs/examples/tutorials` directory and compile, we'll get the `basic-tutorial-1` executable
+```shell
+cd gst-docs/examples/tutorials
+gcc basic-tutorial-1.c -o basic-tutorial-1 `pkg-config --cflags --libs gstreamer-1.0`
+```
+
+After successful compilation, an executable program will be generated in the current directory, use the following command to run
+```shell
+./basic-tutorial-1
+```

+## GStreamer
+
+GStreamer 是一个基于管道的多媒体框架，基于 GObject，以 C 语言写成。凭借 GStreamer，可以很容易地创建各种多媒体功能组件，包括简单的音频回放、音频和视频播放、录音、流媒体和音频编辑。基于流水线设计，可以创建诸如视频编辑器、流媒体广播和媒体播放器等等的很多多媒体应用。
+
+接下来，展示如何在 LPi4A 上运行 GStreamer 的 demo。
+首先，需要安装相关的依赖：
+```shell
+sudo apt install git build-essential libgstreamer* gstreamer1.0-tools
+```
+
+然后拉取相关源码仓库
+```shell
+git clone https://gitlab.freedesktop.org/gstreamer/gst-docs
+```
+
+进入到 `gst-docs/examples/tutorials` 目录下，编译出 `basic-tutorial-1` 可执行程序
+```shell
+cd gst-docs/examples/tutorials
+gcc basic-tutorial-1.c -o basic-tutorial-1 `pkg-config --cflags --libs gstreamer-1.0`
+```
+
+编译成功后会在当前目录下生成可执行程序，使用下面的命令运行即可看到效果：
+```shell
+./basic-tutorial-1
+```
