node方式拉流推流并加水印
var ffmpeg = require('fluent-ffmpeg');const command = ffmpeg('https://outbound-production.explore.org/stream-production-319/.m3u8').videoFilters("movie=black_water.png[watermark]; [in][watermark] overlay=main_w-overlay_w-20:main_h-overlay_h-10 [out]").addOptions(["-vcodec libx264","-preset ultrafast","-acodec aac"]).format("flv").output('rtmp://livepush.gonature.cn/live/qwee?txSecret=39a51cfacc1d5d93216add5b5e0a017e&txTime=60DD7A3B', {end: true}).on("start", function (commandLine) {console.log("commandLine: " + commandLine);}).on("error", function (err, stdout, stderr) {console.log("commandLine: " + '失败');}).on("end", function () {});command.run()使用process_argv传递参数，执行固定的ID之间的任务
启动方式：
node manage.js 1 3
任务id 1-3，包含1和3
const ffmpeg = require('fluent-ffmpeg')
const config = require('./live_push_tasks.json')
const fs = require('fs')
// ffmpeg.setFfmpegPath('/usr/local/ffmpeg/bin/ffmpeg') // /Users/bin/Downloads/ffmpeg 本机
const oneDay = 86400000
const tasks = {} // 正在执行的任务
let begin = 1 // 开始初始值
let end = 100 // 结束初始值
process.argv.forEach(function(val, index, array) {console.log(index + ': ' + val);if (index === 2) {begin = val}if (index === 3) {end = val}
});
const checkAndRun = async function(){console.log('check and run task...', new Date())// 遍历任务列表for(let i in config.tasks){const task = config.tasks[i]const now = new Date()// console.log(now.getDay() === task.weekDay,time >= task.startTime,(!exists || (exists && overwrite)))if(!tasks[task.name] && begin <=task.id && end>=task.id){ // 判断文件是否已存在 或 上一次更新时间距现在是否大于24小时((t)=> {tasks[t.name] = {id: t.id,name: t.name,saveAs: t.saveAs,status: null}// 创建 ffmpeg 任务tasks[t.name].process = ffmpeg('https://outbound-production.explore.org/stream-production-'+task.source+'/.m3u8').videoFilters("movie=black_water.png[watermark]; [in][watermark] overlay=main_w-overlay_w-20:main_h-overlay_h-10 [out]").addOptions(["-vcodec libx264","-preset ultrafast","-acodec aac"]).format("flv").output(task.output, {end: true}).on("start", function (commandLine) {console.log(commandLine)tasks[t.name].status = 'Going'}).on("error", function (err, stdout, stderr) {console.error('record live error: ' + err.message)tasks[t.name].status = 'Error'}).on("end", function () {delete tasks[t.name]}).run();})(task)}}
}
// 格式化输出到控制台
function log(){const list = Object.values(tasks).map(i=>{return { id: i.id, name: i.name, status: i.status || ''}})list.sort((a,b)=> a.id - b.id )console.table(list)
}
function run(){checkAndRun() // 首次立即执行setInterval(checkAndRun, 30000) // 每 30 秒检查一次setInterval(log, 5000) // 日志每 5 秒输出一次
