Owncast:一个人的直播间

owncast是一个单用户的直播工具,带有聊天功能。

程序转码需要用到ffmpeg,建议在一台性能稍好的VPS上安装,安装基本工具:

apt -y update
apt -y install ffmpeg unzip nginx python-certbot-nginx supervisor
systemctl start supervisor nginx
systemctl enable supervisor nginx

下载解压二进制文件:

mkdir -p /opt/owncast && cd /opt/owncast
wget https://github.com/owncast/owncast/releases/download/v0.0.2/owncast-linux-0.0.2.zip
unzip owncast-linux-0.0.2.zip

新建配置文件:

nano config.yaml

写入如下配置:

ffmpegPath: /usr/bin/ffmpeg
webServerPort: 8080
instanceDetails:
name: imlala
title: MapleStory Solo Lotus
summary: "Welcome"
extraUserInfoFileName: "/static/content.md"

- platform: mastodon
url: http://mastodon.something/owncast
videoSettings:
chunkLengthInSeconds: 5
streamingKey: password
offlineContent: static/offline.m4v
streamQualities:
- low:
videoBitrate: 400
scaledWidth: 600
audioPassthrough: true
encoderPreset: veryfast
- medium:
videoBitrate: 800
encoderPreset: fast
- high:
videoBitrate: 2000
encoderPreset: faster

如果你只想开箱即用的话,修改streamingKey后面的值即可,这是你的直播密码。

其他的配置可参考如下地址的说明:

https://owncast.online/docs/configuration/

接下来新建一个supervisor配置文件用于守护owncast的进程:

nano /etc/supervisor/conf.d/owncast.conf

写入如下配置:

[program:owncast]
priority=1
directory=/opt/owncast
command=/opt/owncast/owncast
autostart=true
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/supervisor/owncast.log

更新supervisor配置即可启动owncast:

supervisorctl update

接下来新建nginx站点配置文件用于反向代理:

nano /etc/nginx/conf.d/owncast.conf

写入如下配置:

server {
listen      80;
server_name owncast.imlala.best;
location / {
proxy_pass         http://127.0.0.1:8080;
proxy_http_version 1.1;
proxy_set_header   Upgrade $http_upgrade;
proxy_set_header   Connection "upgrade";
proxy_set_header   Host $http_host;
}
}

使用certbot签一个ssl证书:

certbot --nginx --agree-tos --no-eff-email --email example@qq.com

推流地址:

rtmp://owncast.imlala.best/live

OBS推流设置:

流名称就是你在config.yaml内设置的streamingKey密码。
