发布时间:

所谓流媒bai体技术,是指将连续的影像和声音信息经过du压缩处理后放在网站服务zhi器上dao,让用户能够一边下载一边观看、收听(即所谓的“在线欣赏”),而不需要等整个压缩文件下载到自己的机器上才可以欣赏的网络传输技术。本篇详细介绍流媒体服务器搭建的一种方案。


1、安装nginx

下载 nginx 1.7.11.3 Gryphon

下载链接: http://nginx-win.ecsds.eu/download/nginx 1.7.11.3 Gryphon.zip

解压到 D:\ffmpgtest\nginx目录


2、下载 nginx-rtmp-module

下载链接:https://github.com/arut/nginx-rtmp-module/

解压后到nginx目录下

配置文件 conf\nginx-win.conf 内容如下:


#user  nobody;
# multiple workers works !
worker_processes  2;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  8192;
    # max value 32768, nginx recycling connections+registry optimization = 
    #   this.value * 20 = max concurrent connections currently tested with one worker
    #   C1000K should be possible depending there is enough ram/cpu power
    # multi_accept on;
}

rtmp {
    server {
        listen 1935;
        chunk_size 4000;
        application live {
             live on;
 
             # record first 1K of stream
             record all;
             record_path /tmp/av;
             record_max_size 1K;
 
             # append current timestamp to each flv
             record_unique on;
 
             # publish only from localhost
             allow publish 127.0.0.1;
             deny publish all;
 
             #allow play all;

启动nginx服务器

在nginx目录启动服务

启动命令

nginx.exe -c conf\nginx-win.conf


3、下载ffmpeg

下载链接:https://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-20161230-6993bb4-win64-static.zip

解压到任意目录下,我自己放在了d盘的ffmpegtest目录下。

配置环境变量

好了,可以推送一个流了。


ffmpeg.exe  -re -i D:\WHYQ.mp4 -f flv -c copy -flvflags no_duration_filesize rtmp://localhost:1935/live/test

正在推送


推送完毕,VLC播放器先试一下。

推送,拉取都可以。


后面讲如何在o2的页面上嵌入流媒体播放器。
