使用nginx+rtmp+ffmpeg实现桌面直播

使用nginx+rtmp+ffmpeg实现桌面直播 流媒体服务器搭建 docker run

docker镜像基于添加了rtmp模块的nginx，和ffmpeg

docker pull alfg/nginx-rtmp docker run -d -p 1935:1935 -p 8080:80 --name=nginx-rtmp alfg/nginx-rtmp rtmp模块说明

进入容器内部查看

docker ps | grep alfg/nginx-rtmp docker exec -it [docker镜像id] /bin/sh cat /etc/nginx/nginx.conf

nginx rtmp模块配置如下

rtmp { server { listen 1935; chunk_size 4000; application stream { live on; exec ffmpeg -i rtmp://localhost:1935/stream/$name -c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 2500k -f flv -g 30 -r 30 -s 1280x720 -preset superfast -profile:v baseline rtmp://localhost:1935/hls/$name_720p2628kbs -c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 1000k -f flv -g 30 -r 30 -s 854x480 -preset superfast -profile:v baseline rtmp://localhost:1935/hls/$name_480p1128kbs -c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 750k -f flv -g 30 -r 30 -s 640x360 -preset superfast -profile:v baseline rtmp://localhost:1935/hls/$name_360p878kbs -c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 400k -f flv -g 30 -r 30 -s 426x240 -preset superfast -profile:v baseline rtmp://localhost:1935/hls/$name_240p528kbs -c:a libfdk_aac -b:a 64k -c:v libx264 -b:v 200k -f flv -g 15 -r 15 -s 426x240 -preset superfast -profile:v baseline rtmp://localhost:1935/hls/$name_240p264kbs; } application hls { live on; hls on; hls_fragment_naming system; hls_fragment 5; hls_playlist_length 10; hls_path /opt/data/hls; hls_nested on; hls_variant _720p2628kbs BANDWIDTH=2628000,RESOLUTION=1280x720; hls_variant _480p1128kbs BANDWIDTH=1128000,RESOLUTION=854x480; hls_variant _360p878kbs BANDWIDTH=878000,RESOLUTION=640x360; hls_variant _240p528kbs BANDWIDTH=528000,RESOLUTION=426x240; hls_variant _240p264kbs BANDWIDTH=264000,RESOLUTION=426x240; } } } 推流

使用ffmpeg录屏桌面，视频流推送到搭建好的流媒体服务器。

windows环境 ffmpeg -f gdigrab -r 25 -s 1920*780 -i desktop -f flv rtmp://ip:1935/hls/desktop.1920.flv linux环境 ffmpeg -f x11grab -r 25 -s 1920*780 -qscale 0.01 -i :0.0 -f flv rtmp://ip:1935/hls/desktop.1920.flv 拉流 播放器播放

vlc播放器下载

打开vlc播放器，选择“打开-》网络串流”并输入推流的url，即可从流媒体服务器拉取视频流并播放 vue展示 使用vue-video-player组件，src为推流的url 参考
