图片水印效果

视频水印效果

视频水印梳理java代码实现

 

Java spring boot项目或者maven项目的pom文件中添加以下依赖  

		<!-- https://mvnrepository.com/artifact/org.bytedeco/javacv-platform -->
		<dependency>
			<groupId>org.bytedeco</groupId>
			<artifactId>javacv-platform</artifactId>
			<version>1.5.5</version>
		</dependency>

 核心代码，单类实现，idea创建VideoWatermark  类，复制粘贴下面代码，右键点击run运行主方法即可。

主要有图片文字水印和视频水印两个方法，大家可以根据自己的的需求对方法里的参数修改。
