JAVA VIDEO AUDIO ENCODER(java 中怎么從視頻里面提取音頻)

spring boot項目pom文件中添加以下依賴

<!--https://mvnrepository.com/artifact/ws.schild/jave-core--><dependency><groupId>ws.schild</groupId><artifactId>jave-core</artifactId><version>3.1.1</version></dependency><!--以下依賴根據系統二選一--><!--win系統平臺的依賴--><dependency><groupId>ws.schild</groupId><artifactId>jave-nativebin-win64</artifactId><version>3.1.1</version></dependency><!--linux系統平臺的依賴--><dependency><groupId>ws.schild</groupId><artifactId>jave-nativebin-linux64</artifactId><version>3.1.1</version></dependency>

Java單類實現代碼,復制到Spring boot項目中
