问题描述
我正在尝试在node.js中创建一个服务器,该服务器接收RTMP数据包并将其转换为HLS数据包,然后将其发送回.从iOS不支持RTMP的那一刻起,我就开始创建与每个发布版本兼容的实时流服务.这是我的代码,但是我卡在回调中.很抱歉,我不是JS程序员,这是我进入JS项目的第一步.提前致谢!我的流客户端将是OBS.
I'm trying to create a server in node.js that receives RTMP packets and converts them in HLS packets, then it sends back the packets. I'm doing this to create a livestream service compatible with every dispositive from the moment that iOS doesn't support RTMP. This is my code, but i'm stuck in what i should put into the callback. Sorry for the mess but I'm not a JS programmer and this are my first steps into a JS project. Thanks in advance! My stream client will be OBS.
import { Server } from 'https';
var hls = require('hls-server')(8000);
var ffmpeg = require('fluent-ffmpeg')
// host, port and path to the RTMP stream
var host = 'localhost'
var port = '8000'
var path = '/live/test'
clients = [];
function callback(){
}
fmpeg('rtmp://'+host+':'+port+path, { timeout: 432000 }).addOptions([
'-c:v libx264',
'-c:a aac',
'-ac 1',
'-strict -2',
'-crf 18',
'-profile:v baseline',
'-maxrate 400k',
'-bufsize 1835k',
'-pix_fmt yuv420p',
'-hls_time 10',
'-hls_list_size 6',
'-hls_wrap 10',
'-start_number 1'
]).output('public/videos/output.m3u8').on('end', callback).run()
推荐答案
最好将 express
用作http服务器.
You better try express
as http server.
您可以从 fluent-ffmpeg
中获取视频流,并通过快递路线中的 res
将 .pipe
结果发送到客户端.回调.
You can get from fluent-ffmpeg
a video stream and .pipe
the results to the client, through the res
in the express routes callbacks.
const express = require('express')
const app = express()
const HOST = '...'
const PORT = '...'
const PATH = '...'
let video = fmpeg(`rtmp://${HOST}:${PORT}${PATH}`, { timeout: 432000 }).addOptions([
'-c:v libx264',
'-c:a aac',
'-ac 1',
'-strict -2',
'-crf 18',
'-profile:v baseline',
'-maxrate 400k',
'-bufsize 1835k',
'-pix_fmt yuv420p',
'-hls_time 10',
'-hls_list_size 6',
'-hls_wrap 10',
'-start_number 1'
]).pipe()
app.get('/myLiveVideo', (req, res) => {
res.writeHead(200, {
'Content-Type': 'video/mp4'
})
video.pipe(res) // sending video to the client
})
app.listen(3000)
现在调用 http://localhost:3000/myLiveVideo
应该会返回视频流.
Now calling http://localhost:3000/myLiveVideo
should return the video streaming.
