Nginx搭建RTMP服务器

转RTMP/HLS(学习)

1 安装nginx

1. 拉取镜像（定制版）：docker pull alqutami/rtmp-hls
2. 启动：docker run -d -p 1935:1935 -p 8080:8080 alqutami/rtmp-hls
3. 自定义配置：docker run -d --name rtmp -p 1935:1935 -p 8080:8080 -v ~/Documents/nginx-1.19.2/conf/nginx.conf:/etc/nginx/nginx.conf alqutami/rtmp-hls

2 配置文件

自带，无需更改

# RTMP configuration
rtmp {
    server {
		listen 1935; # Listen on standard RTMP port
		chunk_size 4000; 
		# ping 30s;
		# notify_method get;

		# This application is to accept incoming stream
		application live {    # live为rtmp服务器应用名，用在推流rtmp://localhost:1935/live/cam01
			live on; # Allows live input

			# for each received stream, transcode for adaptive streaming
			# This single ffmpeg command takes the input and transforms
			# the source into 4 different streams with different bitrates
			# and qualities. # these settings respect the aspect ratio.
			exec_push  /usr/local/bin/ffmpeg -i rtmp://localhost:1935/$app/$name -async 1 -vsync -1
						-c:v libx264 -c:a aac -b:v 256k  -b:a 64k  -vf "scale=480:trunc(ow/a/2)*2"  -tune zerolatency -preset superfast -crf 23 -f flv rtmp://localhost:1935/show/$name_low
						-c:v libx264 -c:a aac -b:v 768k  -b:a 128k -vf "scale=720:trunc(ow/a/2)*2"  -tune zerolatency -preset superfast -crf 23 -f flv rtmp://localhost:1935/show/$name_mid
						-c:v libx264 -c:a aac -b:v 1024k -b:a 128k -vf "scale=960:trunc(ow/a/2)*2"  -tune zerolatency -preset superfast -crf 23 -f flv rtmp://localhost:1935/show/$name_high
						-c:v libx264 -c:a aac -b:v 1920k -b:a 128k -vf "scale=1280:trunc(ow/a/2)*2" -tune zerolatency -preset superfast -crf 23 -f flv rtmp://localhost:1935/show/$name_hd720
						-c copy -f flv rtmp://localhost:1935/show/$name_src;			
			drop_idle_publisher 10s; 
		}

		# This is the HLS application
		application show { # show为http服务器应用名，用在推流rtmp://localhost:1935/show/cam01
			live on; # Allows live input from above application
			deny play all; # disable consuming the stream from nginx as rtmp
			
			hls on; # Enable HTTP Live Streaming
			hls_fragment 3;
			hls_playlist_length 20;
			hls_path /mnt/hls/;  # hls fragments path
			# Instruct clients to adjust resolution according to bandwidth
			hls_variant _src BANDWIDTH=4096000; # Source bitrate, source resolution
			hls_variant _hd720 BANDWIDTH=2048000; # High bitrate, HD 720p resolution
			hls_variant _high BANDWIDTH=1152000; # High bitrate, higher-than-SD resolution
			hls_variant _mid BANDWIDTH=448000; # Medium bitrate, SD resolution
			hls_variant _low BANDWIDTH=288000; # Low bitrate, sub-SD resolution
			
			# MPEG-DASH
            dash on;
            dash_path /mnt/dash/;  # dash fragments path
			dash_fragment 3;
			dash_playlist_length 20;			
		}
	}
}

3 转流

//rtsp --> rtmp
ffmpeg -re -i rtsp://admin:qwe123qwe@10.18.30.218:554/h264/ch1/main/av_stream -c copy -f flv rtmp://localhost:1935/live/cam01

//rtsp --> hls
ffmpeg -re -i rtsp://admin:qwe123qwe@10.18.30.218:554/h264/ch1/main/av_stream -c copy -f flv rtmp://localhost:1935/show/cam01

4 访问

• RTMP流：rtmp://localhost:1935/live/cam01

• HLS流：http://localhost:8080/hls/cam01.m3u8

转RTMP/HTTP-FLV(采用)

安装

docker pull rebaltair/nginx-http-flv-module（基于alqutami/rtmp-hls）

运行

docker run -idt -p 8080:9000 -p 1935:1935 rebaltair/nginx-http-flv-module

推流

ffmpeg -re -i rtsp://admin:qwe123qwe@10.18.30.183:554/h264/ch1/main/av_stream -c copy -f flv rtmp://localhost:1935/live/[stream]

访问

• rtmp://ip[:port]/live/[stream]
• http://ip:8080/live?app=live&stream=[stream]
