The NGINX version SHOULD be equal to or greater than 1.2.6, the compatibility with other versions is unknown.
- Linux (recommended) / FreeBSD / MacOS / Windows (limited).
-
Flash player will be no longer supported officially by Adobe after December 31, 2020, refer to Adobe Flash Player EOL General Information Page for details. Plugins that use flash player won't work after the major browsers subsequently remove flash player.
-
flv.js can only run with browsers that support Media Source Extensions.
-
GNU make for activating compiler on Unix-like systems to compile software.
-
GCC for compilation on Unix-like systems or MSVC for compilation on Windows.
-
GDB for debug on Unix-like systems.
-
VLC (recommended) or flv.js (recommended) for playing media streams.
-
PCRE for NGINX if regular expressions needed.
-
OpenSSL for NGINX if encrypted access needed.
-
zlib for NGINX if compression needed.
nginx-http-flv-module has all features that nginx-rtmp-module provides, so DON'T compile nginx-http-flv-module along with nginx-rtmp-module.
For details about build steps, please refer to Building nginx on the Win32 platform with Visual C, and don't forget to add --add-module=/path/to/nginx-http-flv-module in Run configure script step.
If some compilers which do not support x64 perfectly, VS2010 for example, are used to compile the module, please make sure that the default settings are used (target machine type x86).
Download NGINX and nginx-http-flv-module.
Uncompress them.
cd to NGINX source directory & run this:
Compile the module into NGINX
./configure --add-module=/path/to/nginx-http-flv-module
make
make install
or
./configure --add-dynamic-module=/path/to/nginx-http-flv-module
make
make install
If the module is compiled as a dynamic module, the NGINX version MUST be equal to or greater than 1.9.11.
For details of usages of nginx-rtmp-module, please refer to README.md.
For simplicity, transcoding is not used (so -c copy is used):
ffmpeg -re -i MEDIA_FILE_NAME -c copy -f flv rtmp://example.com[:port]/appname/streamname
Some legacy versions of FFmpeg don't support the option -c copy, the options -vcodec copy -acodec copy can be used instead.
The appname is used to match an application block in rtmp block (see below for details).
The streamname can be specified at will but can NOT be omitted.
The default port for RTMP is 1935, if some other ports were used, :port must be specified.
http://example.com[:port]/dir?[port=xxx&]app=appname&stream=streamname
-
If ffplay is used in command line to play the stream, the url above MUST be enclosed by quotation marks, or arguments in url will be discarded (some shells not so smart will interpret "&" as "run in background").
-
If flv.js is used to play the stream, make sure that the published stream is encoded properly, for flv.js supports ONLY H.264 encoded video and AAC/MP3 encoded audio.
The dir is used to match location blocks in http block (see below for details).
The default port for HTTP is 80, if some other ports were used, :port must be specified.
The default port for RTMP is 1935, if some other ports were used, port=xxx must be specified.
The value of app (appname) is used to match an application block, but if the requested app appears in several server blocks and those blocks have the same address and port configuration, host name matches server_name directive will be additionally used to identify the requested application block, otherwise the first one is matched.
The value of stream (streamname) is used to match the name of published stream.
Assume that listen directive specified in http block is:
http {
...
server {
listen 8080; #not default port 80
...
location /live {
flv_live on;
}
}
}
And listen directive specified in rtmp block is:
rtmp {
...
server {
listen 1985; #not default port 1935
...
application myapp {
live on;
}
}
}
And the name of published stream is mystream, then the url of playback based on HTTP is:
http://example.com:8080/live?port=1985&app=myapp&stream=mystream
Since some players don't support HTTP chunked transmission, it's better to specify chunked_transfer_encoding off; in location where flv_live on; is specified in this case, or play will fail.
rtmp://example.com[:port]/appname/streamname
http://example.com[:port]/dir/streamname.m3u8
http://example.com[:port]/dir/streamname.mpd
HTTP-FLV (flv.js)
The directives rtmp_auto_push, rtmp_auto_push_reconnect and rtmp_socket_dir will not function on Windows except on Windows 10 17063 and later versions, because relay in multiple processes mode needs help of Unix domain socket, please refer to Unix domain socket on Windows 10 for details.
It's better to specify the directive worker_processes as 1, because ngx_rtmp_stat_module may not get statistics from a specified worker process in multi-processes mode, for HTTP requests are randomly distributed to worker processes. ngx_rtmp_control_module has the same problem. The problem can be optimized by this patch per-worker-listener.
In addtion, vhost feature is OK in single process mode but not perfect in multi-processes mode yet, waiting to be fixed. For example, the following configuration is OK in multi-processes mode:
rtmp {
...
server {
listen 1935;
server_name domain_name;
application myapp {
...
}
}
}
While the following configuration doesn't work properly for play requests distinated to the second server (whether port is 1935 or not) of non-publisher worker processes:
rtmp {
...
server {
listen 1935;
server_name 1st_domain_name;
application myapp {
...
}
}
server {
listen 1945;
server_name 2nd_domain_name;
application myapp {
...
}
}
}
If NGINX is running in muti-processes mode and socket option SO_REUSEPORT is supported by platform, adding option reuseport for the directive listen will resolve the thundering herd problem.
rtmp {
...
server {
listen 1935 reuseport;
...
}
