我已按照本指南将RTMP设置为HLS流-https://docs.peer5.com/guides/setting-up-hls-live-streaming-server-using-nginx/
RTMP流式传输工作正常,但由于某种原因,我无法让HLS与现有的RTMP服务器链接。我正在使用OBS将数据流传输到RTMP,并将其设置为x264,据我所知,音频的默认编解码器是AAC,所以我不确定为什么不选择它。
当前Nginx.conf
worker_processes auto;
events {
worker_connections 1024;
}
# RTMP configuration
rtmp {
server {
listen 1935; # Listen on standard RTMP port
chunk_size 4000;
# Define the Application
application show {
live on;
pull rtmp://localhost:1935/stream/test;
# Turn on HLS
hls on;
hls_path /mnt/hls/;
hls_fragment 3;
hls_playlist_length 60;
# disable consuming the stream from nginx as rtmp
deny play all;
}
# RTMP video on demand for mp4 files
application vod {
play /mnt/mp4s;
}
# RTMP stream using OBS
application stream {
live on;
}
}
}
http {
sendfile off;
tcp_nopush on;
aio on;
directio 512;
default_type application/octet-stream;
server {
listen 8080;
location / {
# Disable cache

# CORS setup
add_header 'Access-Control-Allow-Origin' '*' always;
add_header 'Access-Control-Expose-Headers' 'Content-Length';
# allow CORS preflight requests
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain charset=UTF-8';
add_header 'Content-Length' 0;
return 204;
}
types {
application/dash+xml mpd;
application/vnd.apple.mpegurl m3u8;

}
root /mnt/;
}
}
}
我已经尝试将该配置中的rtmp链接也更改为内部IP和外部IP,因为可以访问它。我测试了从网络上的另一台计算机观看rtmp,以确认其功能正常。我想避免使用ffmpeg进行代码转换,因为服务器没有这种功能。
所以我整理了一下。基本上,我要寻找的只是将RTMP转换为HLS,而无需进行转码。如果其他人看到了这个并且需要它,这很简单,但是,您确实需要ffmpeg来实现它。从本质上讲,您告诉ffmpeg将流传递给HLS,并且由于OBS已经是正确的视频/音频格式,它将毫无问题地将其接收。我使用的命令是
ffmpeg -re -i rtmp://localhost:1935/stream/test -codec copy -f flv /mnt/hls/stream.m3u8
以这种方式执行对我的CPU几乎没有影响,而这正是我所需要的。
