用树莓派做 RTMP 流直播服务器,可推送至斗鱼直播

在《用树莓派DIY共享鱼缸,支持微信远程喂鱼》一文中,使用了树莓派来做直播服务器。通过安装在树莓派上的摄像头采集实时视频数据流,推送至 RTMP 监听服务器。同时,其他的客户端访问这个 RTMP 服务器就可以观看视频了。下面我们来详细介绍这个模块如何搭建,文末还将给出将直播视频推送至斗鱼直播平台的方法。

需要用的东西和软件说明:

树莓派主板(本文使用树莓派 Zero W 套件,该套件附带一款完美安装摄像头的外壳)
兼容摄像头(本文使用官方摄像头模块,其他 USB 兼容摄像头亦可)
软件方面:
avconv 和 GStreamer 用于采集摄像头捕获的视频流并推送到 RTMP 服务
NGINX 和 RTMP 模块,用于接收视频流,同时提供视频发布功能
Strobe Media Playback,一款基于 Flash 的网页视频播放器

一、配置摄像头

无论是树莓派官方摄像头模块还是其他兼容的USB摄像头,连接好摄像头之后,运行命令去启用摄像头:

sudo raspi-config

编辑系统模块文件。

sudo nano /etc/modules

在这个文件的最后添加一行

bcm2835-v4l2

保存。建议配置好之后重启一下树莓派。然后测试摄像头是否正常工作。

vcgencmd get_camera


输出如图所示表示被识别到。进一步测试拍照。

raspistill -t 2000 -o 1.jpg

执行上面的指令之后,会你用摄像头拍照,并将照片保存在当前目录下,名为 1.jpg。

如果一切正常,恭喜!可以开始下面的步骤了!

二、网络配置

如果你的树莓派使用有线网络的话可以忽略这一步。笔者用的树莓派是 Zero W 版本,没有有线网口,所以必须手动配置无线网络。

sudo nano /etc/network/interfaces

将配置修改为:

auto lo
iface lo inet loopback

allow-hotplug wlan0
auto wlan0

iface wlan0 inet dhcp
        wpa-ssid "WIFISSID"
        wpa-psk "WIFIPASSWORD"

WIFISSID 和 WIFIPASSWORD 分别替换为你的 WIFI 的 SSID 和密码。

网络配置方法可以参考树莓派实验室的其他文章,例如这篇《树莓派 Raspberry Pi 设置无线上网》。

三、安装 NGINX 和 RTMP

我们用 nginx 加上 nginx-rtmp-module 模块作为 RTMP 服务端。这里先安装 nginx 然后再移除它,目的是利用这个过程吧 nginx 相关的依赖安装好并设定好系统环境。这个通过 apt 安装的 nginx 并不能直接使用,因为他并不包含我们需要的 RTMP 模块,所以将它移除。而后我们手工下载 nginx 和 nginx-rtmp-module 模块源码来手工编译安装,以获得我们最终需要的服务端。

sudo apt-get update
#安装 nginx
sudo apt-get -y install nginx
#移除 nginx
sudo apt-get -y remove nginx
sudo apt-get clean
#清空 nginx 的配置文件
sudo rm -rf /etc/nginx/*
#安装编译用的模块
sudo apt-get install -y curl build-essential libpcre3 libpcre3-dev libpcre++-dev zlib1g-dev libcurl4-openssl-dev libssl-dev
#创建存放网页的目录给 nginx 使用
sudo mkdir -p /var/www
#创建编译用的目录
mkdir -p ~/nginx_src
cd ~/nginx_src
#下载 nginx 源码包
wget http://nginx.org/download/nginx-1.11.8.tar.gz
#下载 nginx-rtmp-module 源码包
wget https://github.com/arut/nginx-rtmp-module/archive/master.zip
tar -zxvf nginx-1.11.8.tar.gz
unzip master.zip
cd nginx-1.11.8
#设定编译参数
./configure --prefix=/var/www --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --pid-path=/var/run/nginx.pid --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --with-http_ssl_module --without-http_proxy_module --add-module=/home/pi/nginx_src/nginx-rtmp-module-master
#开始编译安装
make
sudo make install

比较漫长的等待之后,编译安装结束。这时可以测试 nginx 是否安装好。

nginx -v

正常的話,會顯示 nginx 的版本。

配置 nginx。

/etc/nginx/nginx.conf

在末尾添加如下配置:

rtmp {
    server {
        listen 1935;
        chunk_size 4096;
        application live {
            live on;
            record off;
        }
    }
}

重启 nginx 服务。

sudo service nginx start

没有错误提示就表示成功了。
到这里 nginx 和 RTMP 模块都准备好了。

四、安装 avconv 和 GStreamer

安装的组件比较多,如果操作的时候因为软件源的问题总是出现错误难以完成,建议更换软件源试试。笔者用的是清华大学软件源安装的。

sudo nano /etc/apt/sources.list
deb https://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi
deb-src https://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi

开始安装

sudo apt-get update
sudo apt-get install libav-tools
#安装 GStreamer
sudo apt-get install gstreamer1.0-tools
#安装 GStreamer 扩展组件
sudo apt-get  install libgstreamer1.0-0 libgstreamer1.0-0-dbg libgstreamer1.0-dev liborc-0.4-0 liborc-0.4-0-dbg liborc-0.4-dev liborc-0.4-doc gir1.2-gst-plugins-base-1.0 gir1.2-gstreamer-1.0 gstreamer1.0-alsa gstreamer1.0-doc gstreamer1.0-omx gstreamer1.0-plugins-bad gstreamer1.0-plugins-bad-dbg gstreamer1.0-plugins-bad-doc gstreamer1.0-plugins-base gstreamer1.0-plugins-base-apps gstreamer1.0-plugins-base-dbg gstreamer1.0-plugins-base-doc gstreamer1.0-plugins-good gstreamer1.0-plugins-good-dbg gstreamer1.0-plugins-good-doc gstreamer1.0-plugins-ugly gstreamer1.0-plugins-ugly-dbg gstreamer1.0-plugins-ugly-doc gstreamer1.0-pulseaudio gstreamer1.0-tools gstreamer1.0-x libgstreamer-plugins-bad1.0-0 libgstreamer-plugins-bad1.0-dev libgstreamer-plugins-base1.0-0 libgstreamer-plugins-base1.0-dev

这里安装了 avconv 和 GStreamer 两套视频采集组件。 avconv 的使用方式是:

avconv -f video4linux2 -r 24 -i /dev/video0 -f flv rtmp://localhost:1935/live

avconv 采用软编码实现,因此 CPU 消耗比较高,推荐用 GStreamer,GStreamer 的采集使用如下命令:

gst-launch-1.0 -v v4l2src device=/dev/video0 ! 'video/x-raw, width=1024, height=768, framerate=30/1' ! queue ! videoconvert ! omxh264enc ! h264parse ! flvmux ! rtmpsink location='rtmp://树莓派的IP地址/live live=1'

如果希望在后台运行这两个命令可以在命令后面添加 & ,例如:

gst-launch-1.0 -v v4l2src device=/dev/video0 ! 'video/x-raw, width=1024, height=768, framerate=30/1' ! queue ! videoconvert ! omxh264enc ! h264parse ! flvmux ! rtmpsink location='rtmp://树莓派的IP地址/live live=1' &

device=/dev/video0 这个参数可以省去,除非在有多个摄像头的时候,希望指定视频采集自某个指定的摄像头才需要这个参数。
采集的视频怎么播放呢?请看下面介绍。

五、实时视频的呈现

有多种方式呈现直播视频画面:
1、使用 RTMP 播放器播放视频流
例如 VLC 等播放器(桌面版和手机版均有)支持 RTMP 视频流播放,填入 rtmp://树莓派的IP地址/live 即可播放。不过这个软件有数十秒的缓冲延迟,需要设定缓冲时间来缩短延迟。

2、使用 Strobe Media Playback 创建播放页面,通过网页播放视频流
这个是在树莓派上创建一个带有播放功能的网页,播放器选用 Strobe Media Playback,当然你也可以选择其他支持 RTMP 的播放器控件。播放的时候用浏览器打开 http://树莓派的IP地址/index.html 进入播放界面。下面介绍这个播放页面的创建方法。

mkdir -p ~/strobe_src
cd ~/strobe_src
wget http://downloads.sourceforge.net/project/smp.adobe/Strobe%20Media%20Playback%201.6%20Release%20%28source%20and%20binaries%29/StrobeMediaPlayback_1.6.328-full.zip
unzip StrobeMediaPlayback_1.6.328-full.zip
sudo cp -r for\ Flash\ Player\ 10.1 /var/www/html/strobe
sudo nano /var/www/html/index.html

填入如下内容,记得把下面的“树莓派的IP地址”替换成你的树莓派实际的IP地址。IP地址可以通过 ifconfig 命令查看。

<!DOCTYPE html>
<html>
<head>
<title>Live Streaming</title>

<!-- strobe -->
<script type="text/javascript" src="strobe/lib/swfobject.js"></script>
<script type="text/javascript">
  var parameters = {  
     src: "rtmp://{pi_address}/rtmp/live",  
     autoPlay: false,  
     controlBarAutoHide: false,  
     playButtonOverlay: true,  
     showVideoInfoOverlayOnStartUp: true,  
     optimizeBuffering : false,  
     initialBufferTime : 0.1,  
     expandedBufferTime : 0.1,  
     minContinuousPlayback : 0.1,  
     poster: "images/poster.png"  
  };  
  swfobject.embedSWF(
    "strobe/StrobeMediaPlayback.swf"
    , "StrobeMediaPlayback"
    , 1024
    , 768
    , "10.1.0"
    , "strobe/expressInstall.swf"
    , parameters
    , {
      allowFullScreen: "true"
    }
    , {
      name: "StrobeMediaPlayback"
    }
  );
</script>

</head>
<body>
<div id="StrobeMediaPlayback"></div>
</body>
</html>

播放的时候用浏览器打开 http://树莓派的IP地址/index.html 进入播放界面。

3、推送至斗鱼直播平台观看
你可能注意到了 GStreamer 这个命令中有 location 这个参数。这个参数是设定采集到的视频流推向哪里,通过设定这个参数可以将视频流推向任何支持 RTMP 协议的服务器。

gst-launch-1.0 -v v4l2src device=/dev/video0 ! 'video/x-raw, width=1024, height=768, framerate=30/1' ! queue ! videoconvert ! omxh264enc ! h264parse ! flvmux ! rtmpsink location='rtmp://树莓派的IP地址/live live=1'

斗鱼平台同样采用了 RTMP 协议传输直播视频,以斗鱼平台为例来说明一下推流到斗鱼的方法。

首先获取斗鱼的 RTMP 推流地址。开启了直播室之后可以获得推流码。注意,斗鱼的推流码是有时限的,取到推流码需要尽快使用以免过期。


把这两个参数组合起来(中间加上/)。修改之后的命令例如:

gst-launch-1.0 -v v4l2src device=/dev/video0 ! 'video/x-raw, width=1024, height=768, framerate=30/1' ! queue ! videoconvert ! omxh264enc ! h264parse ! flvmux ! rtmpsink location='rtmp://send1.douyu.com/live/1372rSOMdcBJ8UHD?wsSecret=96d2k4ecdf267d17b8e8c38b6a4a6efd&wsTime=59f92e2e&wsSeek=off live=1'

然后就可以开播了。


打个小广告,欢迎大家关注我的斗鱼直播间~
https://www.douyu.com/1372
这里不定期直播宠物鱼。
应用以上技术实现的远程喂鱼项目:
http://make.quwj.com/program/nature-aquarium

总体上三种播放方式都有一定延迟,其中网页 Strobe Media Playback 播放延迟最小,大概在1秒左右。VLC 延迟比较固定默认约20秒,个别平台的版本是可以设置延迟数值的笔者没有亲力尝试。然后是斗鱼平台,斗鱼随着播放时间变长延迟也越来越长,需要刷新直播间页面才会同步。

  1. 文章开头部分的一个树莓派带四个摄像头的图片很吸引我,因为我就有这样的需求,搜索了一下图片这东西好像叫 Multi camera Adapter module,在http://www.robotshop.com/en/arducam-multi-camera-adapter-module-raspberry-pi.html网站上有卖的,但价格挺贵的,还只兼容它自己的摄像头,这就没有办法了。

  9. 我连接c270摄像头本身自带麦克风,如何加入音频一起推流?
    请教命令是什么?目前

  15. 如果推流正常,nginx开启正常,但是网页显示we are unable to the network.we apologize for the inconvenience.说明nginx配置文件里需要在http server中加入如下语句location /stat {
    rtmp_stat all;
    rtmp_stat_stylesheet stat.xsl;
    }
    location /stat.xsl {
    # you can move stat.xsl to a different location
    root /usr/build/nginx-rtmp-module;
    }

    # rtmp control
    location /control {
    rtmp_control all;
    }
    并重启nginx(我没用第一步安装和删除所以无法使用sudo service nginx start,我是使用sudo /usr/sbin/nginx –s stop 关闭;sudo /usr/sbin/nginx 开启;按照路径关闭和开启)原因是在网页服务界面没有加入rtmp播放控件,自己瞎琢磨好久才整好,希望对大家有帮助。

    • 你好,请问怎么算推流正常呢,开启推流后控制台刷新了一些数据但是就阻塞了,这算正常吗?
      而且我按照你的方法修改了conf文件,依然是提示we are unable to the network.we apologize for the inconvenience。
      请问是怎么回事呢,我看你有一句root /usr/build/nginx-rtmp-module;这句是不是需要修改路径的?
      谢谢!
