docker安装OSSRS流媒体直播服务器
docker安装OSSRS流媒体直播服务器
在外界开发中, 如果要实现直播功能.常用的方式有:
1. 通过第三方接口来实现.
可以申请阿里云,腾讯云,网易云,七牛云的直播接口,根据文档,下载集成SDK到项目中,在第三方用户平台上, 创建直播流[就是一个管道].有了直播流以后, 在客户端中集成一个推流[就是基于rtmp协议把视频摄像头采集到的信息push到直播服务器]的播放器或者第三放模块
在另一个客户端中, 集成支持播放rtmp视频信息的播放器插件,基于这个插件向第三方直播服务器获取直播视频.
2. 自己部署搭建直播服务器.
nginx+nginx-rtmp-module+ffmpeg

官方文档：https://github.com/ossrs/srs/wiki
SRS定位是运营级的互联网直播服务器集群，追求更好的概念完整性和最简单实现的代码。SRS提供了丰富的接入方案将RTMP流接入SRS，包括推送RTMP到SRS、推送RTSP/UDP/FLV到SRS、拉取流到SRS。 SRS还支持将接入的RTMP流进行各种变换，譬如将RTMP流转码、流截图、转发给其他服务器、转封装成HTTP-FLV流、转封装成HLS、 转封装成HDS、转封装成DASH、录制成FLV/MP4。SRS包含支大规模集群如CDN业务的关键特性，譬如RTMP多级集群、源站集群、VHOST虚拟服务器 、 无中断服务Reload、HTTP-FLV集群。此外，SRS还提供丰富的应用接口，包括HTTP回调、安全策略Security、HTTP API接口、 RTMP测速。SRS在源站和CDN集群中都得到了广泛的应用Applications。
安装
- 创建自定义网络
sudo docker network create --driver bridge --subnet 172.0.0.0/16 srs_network
# sudo docker network ls
- 创建配置文件
# 使用阿里云镜像安装启动srs
sudo docker run -p 1935:1935 -p 1985:1985 -p 8080:8080 --name srs registry.cn-hangzhou.aliyuncs.com/ossrs/srs:v4.0.34
# 把容器中的配置文件复制出来
sudo mkdir -p /home/docker/srs4
sudo docker cp -a srs:/usr/local/srs/conf /home/docker/srs4/conf
# 把容器中的日志文件复制出来
sudo docker cp -a srs:/usr/local/srs/objs /home/docker/srs4/objs
# 删除容器
sudo docker rm -f srs
- 挂载配置文件并启动
sudo docker run --restart=always -p 1935:1935 -p 1985:1985 -p 8080:8080 --name srs --network srs_network --ip 172.0.0.35 -v /home/docker/srs4/conf/:/usr/local/srs/conf/ -v /home/docker/srs4/objs/:/usr/local/srs/objs/ -d registry.cn-hangzhou.aliyuncs.com/ossrs/srs:v4.0.34
- 通过
http://127.0.0.1:8080查看srs终端信息 - 通过
http://127.0.0.1:1935/live/自定义直播流名称进行直播推流
基于APICloud的acLive直播推流模块实现RTMP直播推流
生成APPLoader，并安装到手机[注意：推流必须依赖于摄像头，而前面我们使用的安卓模拟器是没有办法完成摄像头调用的。]
