在基于vuecli3 与electron的框架外部,实现rtmp流的播放,为什么要写这篇文章,因为确实实现起来踩了很多坑,并没有像web那样导入videoJS 就能实现的,闲话不说,上代码 :
第一个坑 :
须要用到的库vue-video-player
videojs-flash
留神:下面这个两个库 肯定要用npm装置。我试过,其余形式装置实现之后会这个谬误:the flash tech is undefined ,如果你遇到这个谬误,肯定先npm uninstall vue-video-player ,再重新安装一次即可。
第二个坑
播放rtmp须要flash的反对,Electron的实现须要代码加载flash的dll文件来取得反对,Electron的app类中有个getPath 办法,执行以下代码能获取本机的flash文件门路 :app.getPath('pepperFlashSystemPlugin')
我的跑起来获取的地址是:C:WINDOWSsystem32MacromedFlashpepflashplayer64_32_0_0_414.dll
所以让electron反对flash代码 :
app.commandLine.appendSwitch('ppapi-flash-path', app.getPath('pepperFlashSystemPlugin'));
当然最好的计划是可能把dll文件间接打包到我的项目外面跟着我的项目一起走,通过在vue.config.js中增加以下代码实现
pluginOptions: { electronBuilder: { builderOptions: { ... win: { target: 'nsis', icon: './public/app.ico', extraResources: [ { "from": "resources/", "to": "./", } ] } } } }
把dll文件copy到resources文件夹下(根目录与vue.config.js同级)而后批改文件加载门路:
let plugins = '' if( process.arch == 'x64' ){ plugins =process.env.WEBPACK_DEV_SERVER_URL? path.join(__dirname,`../resources/pepflashplayer64_32_0_0_238.dll`) :path.join(__dirname,`../pepflashplayer64_32_0_0_238.dll`) }else{ plugins =process.env.WEBPACK_DEV_SERVER_URL? path.join(__dirname,`../resources/pepflashplayer32_29_0_0_238.dll`) :path.join(__dirname,`../pepflashplayer32_29_0_0_238.dll`) }app.commandLine.appendSwitch('ppapi-flash-path', plugins)
第三个坑
以上的货色搞完根本能够实现播放了,然而打包之后发现不能够,看景象 像是加载不出flash,解决方案就是在启动 Electron 主过程的时候,启动一个本地 express 服务器,配置一下动态文件地址,而后渲染过程通过这个服务器拿到页面,在而后就能够启动 flash 了。
上代码:
'use strict'import { app, BrowserWindow,ipcMain } from 'electron' import { createProtocol } from 'vue-cli-plugin-electron-builder/lib'// import installExtension, { VUEJS_DEVTOOLS } from 'electron-devtools-installer'const isDevelopment = process.env.NODE_ENV !== 'production'// Keep a global reference of the window object, if you don't, the window will// be closed automatically when the JavaScript object is garbage collected.let winlet allowPort =nullimport express from 'express'const net = require('net');async function portInUse(port){ return new Promise((resolve, reject)=>{ let server = net.createServer().listen(port); server.on('listening',function(){ server.close(); resolve(port); }); server.on('error',function(err){ if(err.code == 'EADDRINUSE'){ port++; reject(err); } }); });}const tryUsePort = function(port,_portAvailableCallback){ portInUse(port).then((port)=>{ _portAvailableCallback(port); }).catch((err)=>{ console.log(port+" ====被占用====:\n"); port++; tryUsePort(port,_portAvailableCallback); }) }tryUsePort(9080,function(port){ // do something ... console.log(port+" ====端口:"+port+"可用====\n"); allowPort = port // net.createServer().listen(port); //解决flash本地file不平安问题 if (process.env.NODE_ENV === "production") { let server = express(); server.use(express.static(__dirname)); server.listen(port); } const winURL = process.env.NODE_ENV === 'development' ? `http://localhost:${allowPort}` // : `file://${__dirname}/index.html` //解决flash在file下不平安的问题 : `http://localhost:${allowPort}/index.html` console.log(winURL) const path = require('path') let plugins = '' if( process.arch == 'x64' ){ plugins =process.env.WEBPACK_DEV_SERVER_URL? path.join(__dirname,`../resources/pepflashplayer64_32_0_0_238.dll`) :path.join(__dirname,`../pepflashplayer64_32_0_0_238.dll`) }else{ // plugins =process.env.WEBPACK_DEV_SERVER_URL? path.join(__dirname,`../resources/pepflashplayer32_29_0_0_238.dll`) :path.join(__dirname,`../pepflashplayer32_29_0_0_238.dll`) plugins =app.getPath('pepperFlashSystemPlugin') }console.log(app.getPath('pepperFlashSystemPlugin') ) app.commandLine.appendSwitch('ppapi-flash-path', plugins) // Optional: Specify flash version, for example, v17.0.0.169 function createWindow() { // Create the browser window. win = new BrowserWindow({ width: 1000, height: 580, webPreferences: { nodeIntegration: true, plugins: true, webSecurity: false //勾销跨域 }, autoHideMenuBar:true, maximizable: false, resizable: false, frame: false, }) if (process.env.WEBPACK_DEV_SERVER_URL) { // Load the url of the dev server if in development mode win.loadURL(process.env.WEBPACK_DEV_SERVER_URL) // if (!process.env.IS_TEST) win.webContents.openDevTools() } else { //批改前 createProtocol('app') // win.loadURL('app://./index.html') //批改后 win.loadURL(winURL) } win.webContents.openDevTools({ mode: 'detach' }) win.on('closed', () => { win = null }) } // Quit when all windows are closed. app.on('window-all-closed', () => { // On macOS it is common for applications and their menu bar // to stay active until the user quits explicitly with Cmd + Q if (process.platform !== 'darwin') { app.quit() } }) app.on('activate', () => { // On macOS it's common to re-create a window in the app when the // dock icon is clicked and there are no other windows open. if (win === null) { createWindow() } }) // This method will be called when Electron has finished // initialization and is ready to create browser windows. // Some APIs can only be used after this event occurs. app.on('ready', async () => { // if (isDevelopment && !process.env.IS_TEST) { // // Install Vue Devtools // try { // await installExtension(VUEJS_DEVTOOLS) // } catch (e) { // console.error('Vue Devtools failed to install:', e.toString()) // } // } createWindow() })
以上就是局部代码能看清楚解决逻辑,
第四个坑
port占用,通过net对象 写一个递归加一点判断 获取以后可用端口,代码如上
第五个坑
到当初你感觉完事大吉了,然而只能开心一会会,在某些状况下还是会呈现flash加载解体问题,这个时候你就要核查下你的flash 版本问题,我试过 30以上都不行29能够,举荐这个版本:pepflashplayer64_29_0_0_140.dll
pepflashplayer32_29_0_0_140.dll
备注:我的上述代码只是兼容了64位的电脑,如果须要兼容32位电脑自行加点判断即可
