docker安装nginx+rtmp模块搭建服务器实现ffmpeg推流+ffplay播放
拉取镜像

1
docker pull alfg/nginx-rtmp

创建并运行容器，映射出两个端口1935、80

1
docker run -itd -p 1935:1935 -p 8080:80 --name nginx-rtmp-test alfg/nginx-rtmp

流默认地址为：rtmp://ip:port/stream/自定义名称

ffmpeg推流 将视频文件推流至rtmp服务器

1
ffmpeg -re -i video.mp4 -f flv rtmp://127.0.0.1:1935/stream/123

使用ffplay播放rtmp流

1
ffplay rtmp://127.0.0.1:1935/stream/123

ok rtmp服务器 搭建成功，接下来就是推流了（这里列举三种方式）

第一种：利用OBS Studio推送直播到这个地址

1
rtmp://服务器ip:1935/stream/自定义名称

第二种：ffmpeg推送本地视频为直播流

1
ffmpeg -re -i /home/holle.flv -vcodec copy -acodec aac -ar 44100 -f flv rtmp://192.168.1.201:1935/stream/example

第三种：利用javacv推本地摄像头视频到流媒体服务器（代码实现如下）
