一、故事
前不久干项目，涉及到在线学习，简单来说就是对文章、视频进行在线学习，这个时候问题出现了，就是在上传视频的时候，速度很是慢，除此之外，视频播放也是卡的鸭皮，然后就开始疯狂网上搜刮知识，最终解决方案如下。
二、解决方案
1、视频采用切片上传，通过调用后端切片上传接口进行上传
2、切片上传结束后通过合并切片接口进行合并成为完整的视频
3、调用 ffmpeg 工具进行视频转 m3u8 格式形成 ts 切片
4、ts 切片多线程上传至 MinIO or OSS
5、返回 m3u8 格式文件地址，前端集成播放器进行播放。
三、项目地址
码云：https://gitee.com/sirwsl/uploadWheel
GitHub： https://github.com/sirwsl/uploadWheel
四、demo 效果展示
五、实现过程
1、下载 ffmpeg
为了开发方便，建议下载 windows 和 linux 两个版本
💩 比较懒的也可以跳过，毕竟代码里面我已经弄好了 💩
PS：此处需要注意，由于网上说的基本都需要配置环境变量，所以此处需要注意，下载的文件，按上图方式选择自己适合的版本下载解压。不需要配置环境变量
2、开始构建 springBoot 程序
1）导入依赖：
关键依赖项

3、确定项目结构
为了开发方便，同时以后谁都能启动这项目，所以把 ffmpeg 的两个版本都丢进来。需要注意版本问题。
小事故：windows 的 ffmpeg 倒是容易搞到，毕竟就只需要两个 exe，问题是 linux 版本的时候出现了问题，因为是采用 docker 打包，所以我不想去什么配置什么环境变量、下载 ffmpeg 之类的。所以 ffmpeg 的 linux 版本选择很重要。
开始时候我直接打包后，发现这个 demo 是运行不了的，因为读取不到 exe 文件，之后尝试了去 linux 安装好后 copy 下来，发现也不行（因为姿势不对）所以下载时候版本很重要。
六、开始编码
1、编写配置文件
PS：1）minIo or OSS 配置文件，任选其一进行配置
2）thymeleaf 部分可以不要，此处为了展示 demo
server: port: 8080 minio: url: #http:// access: #admin secret: #admin #m3u8视频转换配置 m3u8: convertor: base-path: /file/m3u8/ temp-path: /file/temp/ big-path: /file/big/ proxy: m3u8/ ali: oss: end-point: access-key-id: access-key-secret: bucket-name: websources url: ali-url: get-file-url: ${aliyun.oss.url}${aliyun.oss.fileDir} my-host-url: # 应用名称 spring: application: name: minioDemo servlet: multipart: max-file-size: 2048MB max-request-size: 2048MB resources: static-locations: classpath:static/ thymeleaf: cache: false check-template: true # 检查模板是否存在，然后再呈现 check-template-location: true # 检查模板位置是否正确（默认值 :true ） enabled: true # 开启 MVC Thymeleaf 视图解析（默认值： true ） encoding: UTF-8 # 模板编码 excluded-view-names: # 要被排除在解析之外的视图名称列表，⽤逗号分隔 mode: HTML5 # 要运⽤于模板之上的模板模式。另⻅ StandardTemplate-ModeHandlers( 默认值： HTML5) prefix: classpath:/templates/ # 在构建 URL 时添加到视图名称前的前缀（默认值： classpath:/templates/ ） suffix: .html # 在构建 URL 时添加到视图名称后的后缀（默认值： .html ） servlet: content-type: text/html #Content-Type 的值（默认值： text/html ）
2、读取 ffmpeg
先写好 config 来读取 ffmpeg，因为我们没配置环境变量，所以这个很关键
package com.wslhome.demo.config;
import lombok.SneakyThrows;
import lombok.extern.slf4j.Slf4j;
import net.bramp.ffmpeg.FFmpeg;
import net.bramp.ffmpeg.FFprobe;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
* ffmpeg 工具路径设置
* @Author sirwsl
* @Version 1.0
*/
@Configuration
@Slf4j
public class FFmpegConfig {
@SneakyThrows
@Bean
public FFmpeg fFmpeg() {
String path = System.getProperty("user.dir");
if (isLinux()){
path+="ffmpeg/ffmpeg";
}else if (isWindows()){
path+="/ffmpeg-win/ffmpeg/bin/ffmpeg.exe";
}
log.info("ffmpeg.exe 路径为{}",path);
return new FFmpeg(path);
}
@SneakyThrows
@Bean
public FFprobe fFprobe() {
String path = System.getProperty("user.dir");
if (isLinux()){
path+="ffmpeg/ffprobe";
}else if (isWindows()){
path+="/ffmpeg-win/ffmpeg/bin/ffprobe.exe";
}
log.info("ffprobe.exe 路径为{}",path);
return new FFprobe(path);
}
public static boolean isLinux() {
return System.getProperty("os.name").toLowerCase().contains("linux");
}
public static boolean isWindows() {
return System.getProperty("os.name").toLowerCase().contains("windows");
}
}
3、编写存储路径配置文件
因为上传切片、合并文件、m3u8 转码等会涉及到较多的临时文件，所以得对这些乱七八糟的文件夹进行管理
package com.wslhome.demo.config;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
/**
* @Author wsl
* @Version 1.0
*/
@Data
@Component
@ConfigurationProperties(prefix = "m3u8.convertor")
public class FilePath {
/**
* 文件上传临时路径 (本地文件转换不需要)
*/
private String tempPath = "/file/tmp/";
/**
* m3u8文件转换后，储存的根路径
*/
private String basePath = "/file/m3u8/";
/**
* m3u8文件转换后，储存的根路径
*/
private String bigPath = "/file/big/";
private String proxy = "m3u8/";
}
3、来个线程池，管理多线程上传
package com.wslhome.demo.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import java.util.concurrent.Executor;
/**
* 线程池配置
*
* @author sirwsl
* @date 2022/01/11-11:14
**/
@Configuration
@EnableAsync
public class SpringAsyncConfig {
/**
* 线程池参数根据minIO设置，如果开启线程太多会被MinIO拒绝
* @return ：
*/
@Bean("minIOUploadTreadPool")
public ThreadPoolTaskExecutor asyncServiceExecutorForMinIo() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
// 设置核心线程数，采用IO密集 h/(1-拥塞)
executor.setCorePoolSize(6);
// 设置最大线程数,由于minIO连接数量有限，此处尽力设计大点
executor.setMaxPoolSize(500);
// 设置线程活跃时间（秒）
executor.setKeepAliveSeconds(30);
// 设置默认线程名称
executor.setThreadNamePrefix("minio-upload-task-");
// 等待所有任务结束后再关闭线程池
executor.setWaitForTasksToCompleteOnShutdown(true);
//执行初始化
executor.initialize();
return executor;
}
/**
* oss async
* @return
*/
@Bean("ossUploadTreadPool")
public ThreadPoolTaskExecutor asyncServiceExecutorForOss() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
// 设置核心线程数，采用IO密集 h/(1-拥塞)
executor.setCorePoolSize(8);
// 设置最大线程数,由于minIO连接数量有限，此处尽力设计大点
executor.setMaxPoolSize(120);
// 设置线程活跃时间（秒）
executor.setKeepAliveSeconds(30);
// 设置默认线程名称
executor.setThreadNamePrefix("ossUploadTask-");
// 等待所有任务结束后再关闭线程池
executor.setWaitForTasksToCompleteOnShutdown(true);
//执行初始化
executor.initialize();
return executor;
}
}
4、编写 minIO or OSS 的上传组件
这玩意以 OSS 为例，Google 一下，到处都是
1）阿里
package com.wslhome.demo.config;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Component
@ConfigurationProperties(prefix = "ali.oss")
@Data
public class AliOssProperties {
/**
* OSS配置信息
*/
private String endpoint;
private String accessKeyId;
private String accessKeySecret;
private String bucketName;
private String myHostUrl;
private String url;
private String aliUrl;
}
2）OSS 组件
package com.wslhome.demo.component;
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.model.*;
import com.wslhome.demo.config.AliOssProperties;;
import lombok.Getter;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.springframework.stereotype.Component;
import org.springframework.web.multipart.MultipartFile;
import javax.annotation.Resource;
import java.io.*;
import java.net.URL;
import java.util.*;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.LinkedBlockingQueue;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;

7、写个 Controller

八、前端代码
1、封装后的 JS
前端为了万能兼容，以后管你啥语言都能够移植过去，因此就采用最古老的 XMLHttpRequest 请求方式。这里做了封装，拿走不谢。
/************************
* 普通文件上传
* *********************
*/
function request(method,path,param,callback) {
let XHR = null;
if (window.XMLHttpRequest) {
XHR = new XMLHttpRequest();
} else if (window.ActiveXObject) {
XHR = new ActiveXObject("Microsoft.XMLHTTP");
} else {
XHR = null;
}
if (XHR) {
XHR.open(method, path);
XHR.onreadystatechange = function () {
if (XHR.readyState == 4 && XHR.status == 200) {
callback(XHR.responseText);
}
}
}
XHR.send(param);
}
/**
* 切片上传
* @returns {*}
*/
function partUpload(GUID, partFile, name, chunks, chunk, partUrl, partMethod,callback) {
const form = new FormData();
form.append("guid", GUID);
form.append("file", partFile); //slice方法用于切出文件的一部分
form.append("fileName", name);
form.append("chunks", chunks); //总片数
form.append("chunk", chunk); //当前是第几片
return request(partMethod,partUrl,form,callback);
}
/**
* 文件合并
* @returns {*}
*/
function mergeFile(GUID, name, mergeUrl, partMethod,callback) {
const formMerge = new FormData();
formMerge.append("guid", GUID);
formMerge.append("fileName", name);
return request(partMethod,mergeUrl,formMerge,callback);
}
/**
* 生成id
* @returns {string}
*/
function guid(prefix) {
let counter = 0;
let guid = (+new Date()).toString(32),
i = 0;
for (; i < 5; i++) {
guid += Math.floor(Math.random() * 65535).toString(32);
}
return (prefix || 'sirwsl_') + guid + (counter++).toString(32);
}

九、收尾
截至目前，项目正常来说应该可以在 windows 上跑起来了，但是不能够在 linux 上跑更不能 docker run，因此我们来写个 dockerfile
1、dockerfile 编写
#指定基础镜像，在其上进行定制
FROM java:8
#维护者信息
MAINTAINER wangshilei <sirwsl@163.com>
VOLUME /tmp
COPY target/uploadWheel-1.jar upload-wheel.jar
COPY ffmpeg-linux/ffmpeg /ffmpeg
RUN bash -c "touch /upload-wheel.jar" &&\
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime &&\
echo "Asia/Shanghai" >> /etc/timezone
EXPOSE 8080
ENTRYPOINT [ "java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/upload-wheel.jar" ]
2、编写 nginx 配置文件
location /m3u8 { types{ application/vnd.apple.mpegurl m3u8; video/mp2t ts; } proxy_pass xxx access_log off; add_header Cache-Control no-cache; }
如果涉及到跨域请加入
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,OPTIONS always;
add_header Access-Control-Allow-Credentials true always;
add_header Access-Control-Allow-Headers DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization,x-auth-token always;
十、优化
在调用 ffmpeg 进行转码时候，上面已经优化过，1G 视频转码大概需要 10 秒，在没优化之前大概需要 50 多分钟，如果觉得慢自己去优化。
优化前：
优化后：
优化参数：
"-vsync", "2",
"-c:v", "copy",
"-c:a", "copy",
"-tune", "fastdecode",
"-hls_wrap", "0",
"-hls_time", "10",
"-hls_list_size", "0",
"-threads", "12"
十一、项目缺陷
1、文件在下载时候，没办法下载视频文件，因为视频都被切片了，因为我们项目不需要，所以就没写
2、多线程上传没有优化、需要自己根据系统情况进行优化
3、不管是 linux 还是 window 打成 jar 包要运行，需注意 jar 包位置与 ffmpeg 文件的位置，不然运行不了
4、因为开发和部署方便，所以该项目只是做了在 idea、和 docker 中能够平稳运行
