Spring boot 整合 ffmpeg 实现给视频添加文字水印 只有上传minio(理论通用！！)

只要有ffmpeg 命令理论可以实现所有ffmpeg 能做的的事儿！！

思路：
前端上传视频通过commons-io的FileUtils.copyInputStreamToFile()将流复制到文件中 java执行ffmpeg 命令对这个文件进行转换输出到另外一个临时文件 在将添加水印后的文件转成inputStream流上传到minio（本人小白 可能有更好的思路！！！）
上代码：

首先是minio的配置文件不需要的掠过

application.yml

spring:
  servlet:
    multipart:
      max-file-size: 200MB
      max-request-size: 200MB
minio:
  endpoint: http://192.168.22.129:9090  #minio地址 注意一定要加 协议不然报错
  accessKey: admin  # 账号
  secretKey: admin123456 #密码
  bucketName: text # 桶的名字（可以理解为文件夹目录）

MinIoClientConfig：

import io.minio.MinioClient;
import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

@Data
@Component
public class MinIoClientConfig {
    @Value("${minio.endpoint}")
    private String endpoint;
    @Value("${minio.accessKey}")
    private String accessKey;
    @Value("${minio.secretKey}")
    private String secretKey;

    /**
     * 注入minio 客户端
     * @return
     */
    @Bean
    public MinioClient minioClient(){

        return MinioClient.builder()
                .endpoint(endpoint)
                .credentials(accessKey, secretKey)
                .build();
    }

}
