SpringBoot 实现大文件视频转码（转码基于 FFMPEG 实现）(1)
/**
获取文件名
@param filePath
@return java.lang.String
@author zxzhang
@date 2019/12/10
*/
public String getFileName(String filePath) {
return filePath.substring(filePath.lastIndexOf(BootstrapConst.PATH_SEPARATOR) + 1, filePath.lastIndexOf("."));
}
}
class PrintStream extends Thread {
java.io.InputStream __is = null;
public PrintStream(java.io.InputStream is) {
__is = is;
}
@Override
public void run() {
try {
while (this != null) {
int _ch = __is.read();
if (_ch != -1) {
System.out.print((char) _ch);
} else {
break;
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
2、BootstrapConst 类?
package com.openailab.oascloud.file.common.consts;
/**
@Classname: com.openailab.oascloud.security.common.consts.BootstrapConst
@Description: 简单常量定义
@Author: zxzhang
@Date: 2019/10/8
*/
public class BootstrapConst {
/**
文件缓冲区大小
*/
public static final Integer INPUT_BUFFER_SIZE = 8192;
/**
文件分隔符
*/
public static final char PATH_SEPARATOR = '/';
/**
文件点
*/
public static final char SPOT = '.';
/**
常量一
*/
public static final Integer ONE = 1;
/**
成功
*/
public static final Integer SUCCESS = 1;
/**
失败
*/
public static final Integer FAIL = 0;
/**
true
*/
public static final Boolean TRUE = true;
/**
false
*/
public static final Boolean FALSE = false;
}
三、FFMPeg DockerFile 实现
首先我们构建具有 JDK1.8 和 FFMPeg 环境的镜像
FROM jrottenberg/ffmpeg:centos
MAINTAINER oas.cloud
ADD jdk-8u231-linux-x64.tar.gz /usr/local/
ENV JAVA_HOME /usr/local/jdk1.8.0_231
ENV CLASSPATH JAVA_HOME/lib/tools.jar
ENV PATH JAVA_HOME/bin
WORKDIR /usr/local/oas/
然后将上述文件构建出的镜像的 tag 打为我们自己的镜像仓库地址，改为 10.12.1.202:8088/oascloud/ffmpeg:v1.0，我们的应用程序就可以以上述镜像文件（10.12.1.202:8088/oascloud/ffmpeg:v1.0）为基础构建出新的应用程序镜像，应用程序的 DockerFile 如下：
FROM 10.12.1.202:8088/oascloud/ffmpeg:v1.0
MAINTAINER oas.cloud
ENV LC_ALL=zh_CN.utf8
ENV LANG=zh_CN.utf8
ENV LANGUAGE=zh_CN.utf8
RUN localedef -c -f UTF-8 -i zh_CN zh_CN.utf8
ARG JAR_FILE
COPY ${JAR_FILE} /usr/local/oas/
WORKDIR /usr/local/oas/
代码结构如下：
附上 Kubernetes 编排文件，deploy.yaml 内容如下：
