加速地址

使用

vue2

1. 新建vue2项目
2. 安装@ffmpeg/ffmpeg @ffmpeg/core包

yarn add @ffmpeg/ffmpeg @ffmpeg/core

3. 编写代码

4. 编辑vue.config.js

const path = require('path');
const express = require('express');
const { defineConfig } = require('@vue/cli-service')module.exports = defineConfig({transpileDependencies: true,publicPath:"/",configureWebpack: {devServer: {//如果vuecli是老版本需要使用beforeonBeforeSetupMiddleware: ({app}) => {app.use("/node_modules/",express.static(path.resolve(__dirname, "node_modules")));app.use((_, res, next) => {res.setHeader("Cross-Origin-Opener-Policy", "same-origin");res.setHeader("Cross-Origin-Embedder-Policy", "require-corp");next();});}}}
})

5. 运行测试项目

需要新版谷歌浏览器、edge浏览器以及火狐浏览器，360浏览器目前测试不可以。

选择视频文件然后点击开始

vue3

1. 新建vue3项目
2. 安装@ffmpeg/ffmpeg @ffmpeg/core包
   
3. 修改App.vue

4. 修改vue.config.js

const zlib = require('zlib');
const path = require("path");
const express = require("express");
const { defineConfig } = require("@vue/cli-service");module.exports = defineConfig({outputDir: "dist",indexPath: "index.html",transpileDependencies: false,productionSourceMap: true,runtimeCompiler: true,lintOnSave: true,parallel: true,integrity: true,publicPath: process.env.NODE_ENV === "production" ? "/vue-app/" : "/",configureWebpack: {devServer: {onBeforeSetupMiddleware: ({ app }) => {app.use("/node_modules/",express.static(path.resolve(__dirname, "node_modules")));app.use((_, res, next) => {res.setHeader("Cross-Origin-Opener-Policy", "same-origin");res.setHeader("Cross-Origin-Embedder-Policy", "require-corp");next();});},},},pluginOptions: {compression: {brotli: {filename: '[file].br[query]',algorithm: 'brotliCompress',include: /\.(js|css|html|svg|json)(\?.*)?$/i,compressionOptions: {params: {[zlib.constants.BROTLI_PARAM_QUALITY]: zlib.constants.BROTLI_MAX_QUALITY,},},minRatio: 0.8,},gzip: {filename: '[file].gz[query]',algorithm: 'gzip',include: /\.(js|css|html|svg|json)(\?.*)?$/i,compressionOptions: { level: zlib.constants.Z_BEST_COMPRESSION },minRatio: 0.8,},},prettify: false,},
});

5. 运行测试项目
   同vue2

nginx部署

执行yarn run build打包，在nginx下新建文件夹ffmpegswam，将内容复制过去

修改nginx.conf文件
增加如下代码

 server {listen       8088;server_name  localhost;#charset koi8-r;#access_log  logs/host.access.log  main;location / {# set response headeradd_header 'Cross-Origin-Opener-Policy' 'same-origin';add_header 'Cross-Origin-Embedder-Policy' 'require-corp';root   ffmpegswam;index  index.html index.htm;}}

全部代码如下

#error_log  logs/error.log  notice;

}

启动nginx或者重新加载项目 nginx -s reload
访问lcoalhost:8088

如果是360浏览器运行报错如下
