RTSP视频流播放几种解决方式

RTSP视频流播放几种解决方式

一、使用FFMPEG把RTSP转RTMP 拉流转码到Nginx +Nginx-rtmp-moudle

首先要先下载ffmpeg

第三方下载：https://linux.softpedia.com/get/Multimedia/Video/FFmpeg-3054.shtml ，

官网：http://ffmpeg.org/download.html，github官网也有。

安装参考https://www.jianshu.com/p/1be929404528

中间可能因环境不同坑比较多，网上的解决方案也比较成熟可以多搜索。
安装Nginx和Nginx-rtmp-moudle

主要步骤解压完Nginx包后 ./configruation –add-module=/你的路径/nginx-rtmp-module-master 加上这个模块然后make makeinstall

之后修改Nginx.conf 加上rtmp相应的配置安装和配置参考：https://www.cnblogs.com/bluesky-yuan/p/10148700.html 这个坑相对较少。
完成上述两部之后可以开始推流了

推流命令示例：ffmpeg -re -rtsp_transport tcp -i rtsp://admin:njxyj2019@11.15.159.26:554/h264 -tune zerolatency -vcodec libx264 -b:v 400k -s 720x576 -r 25 -f flv rtmp://你的ip:你在Nginx.conf下修改的rtmp端口/conf中的application/自定义流名（随便）

关于ffmpeg的各种参数指令含义可以通过百度获取太多了就不写了
上面完成后基本就可以通过 rtmp://你的ip:你在Nginx.conf下修改的rtmp端口/conf中的application/自定义流名（随便）访问nginx来获取视频流播放了

二、使用FFMPEG+PingOS

同上第一步
安装 PingOS 全中文官网安装配置一条龙都有（如果你的服务器不能连接外网，你需要下载安装后把release.sh 脚本中的代码一点点自己执行，所有需要下载的操作都提前下载好安装好放到服务器上再执行之后的操作。）

PingOS主要还是基于Nginx及他的一些moudle，可以说主要基于Nginx-rtmp-mouldle

所以说如果觉得对流的流畅度及一些别的不满意主要还是通过修改内置的nginx.conf来调整。
拉流推送到PingOS， obs或者FFmpeg 都可以实现 ffmpeg还是同上的第三步 obs可以自行百度

三、经验分享

推荐使用FFMPEG+PingOS

测试表明使用PingOS的首帧播放和延迟很低，rtmp流稳定流畅很少卡顿
PingOS 支持多种播放模式 hls hls+ rtmp ts flv ，支持多种协议 rtmp http 和https（听说rtsp也在开发中）同一个推流可以有多种播放方式

测试之后 rtmp实时性最高延迟最低但是有些前端播放器会获取首帧之后就卡住（由于没有前端配合没有测试很多播放器） rtmp的劣势主要还是依赖于flash

hls 的延迟和流畅度也很不错，但是实时性差一些，hls主要通过储存切片的方式实现播放，可以通过配置每个切片的大小为多少，把存储的切片播完时每次切换切片会微微卡顿一下，优势可以通过http协议请求不依赖于flash

别的方式测试了之后延迟和首帧播放时间很长也没有过多研究如有需要可以对应官网多多研究配置。
贴一个我们项目的nginx配置作为参考
