+# PythonPlugin
+This is a Python plugin project for Ant Media Server. You can use this project to interface with python program to modify Audio/Video data, apply AI
+With this plugin you can find:
+- Accessing the Ant Media Server ie. AntMediaApplicationAdaptor class
+- Registration of the plugin as the PacketListener and/or FrameListener 
+- Consuming packets and/or frames
+- REST interface implementation
+
+# Prerequests
+- Install Ant Media Server
+- Install Maven 
+
+# Quick Start
+
+- Clone the repository and go the Sample Plugin Directory
+  ```sh
+  git clone https://github.com/ant-media/Plugins.git
+  cd Plugins/PythonPlugin/
+  ```
+- Build the Sample Plugin
+  ```sh
+  sudo ./redeploy.sh
+  ```
+- Publish/unPublish a Live Stream to Ant Media Server with WebRTC/RTMP/RTSP
+- Check the logs on the server side 
+  ```
+  tail -f /usr/local/antmedia/log/ant-media-server.log
+  ```
+  You would see the following logs
+  ```
+  ...
+  ...
+  ...
+  io.antmedia.plugin.PythonPlugin - *************** Stream Started: streamIdXXXXX ***************
+  ...
+  ...
+  ...
+  io.antmedia.plugin.PythonPlugin - *************** Stream Finished: streamIdXXXXX ***************
+  ...
+  ...
+  ...
+  ```
+
+For more information about the plugins, [visit this post](https://antmedia.io/plugins-will-make-ant-media-server-more-powerful/)
