## Compatibility

The [NGINX](http://nginx.org) version **SHOULD** be equal to or greater than 1.2.6, the compatibility with other versions is unknown.

## Systems supported

* Linux (recommended)/FreeBSD/MacOS/Windows (limited).

## Players supported

* [VLC](http://www.videolan.org) (RTMP & HTTP-FLV)/[OBS](https://obsproject.com) (RTMP & HTTP-FLV)/[JW Player](https://www.jwplayer.com) (RTMP)/[flv.js](https://github.com/Bilibili/flv.js) (HTTP-FLV).

### Note

[flv.js](https://github.com/Bilibili/flv.js) can only run with browsers that support [Media Source Extensions](https://www.w3.org/TR/media-source).

## Prerequisites

* GCC for compilation on Unix-like systems or MSVC for compilation on Windows.

* GDB for debug on Unix-like systems.

* [FFmpeg](http://ffmpeg.org) or [OBS](https://obsproject.com) for publishing media streams.

* [VLC](http://www.videolan.org) (recommended) or [flv.js](https://github.com/Bilibili/flv.js) (recommended) for playing media streams.

* [PCRE](http://www.pcre.org) for NGINX if regular expressions needed.

* [OpenSSL](https://www.openssl.org) for NGINX if encrypted access needed.

* [zlib](http://www.zlib.net) for NGINX if compression needed.

## Build

### Note

nginx-http-flv-module has all features that [nginx-rtmp-module](https://github.com/arut/nginx-rtmp-module) provides, so **DON'T** compile nginx-http-flv-module along with [nginx-rtmp-module](https://github.com/arut/nginx-rtmp-module).

### On Windows

For details about build steps, please refer to [Building nginx on the Win32 platform with Visual C](http://nginx.org/en/docs/howto_build_on_win32.html), and don't forget to add `--add-module=/path/to/nginx-http-flv-module` in `Run configure script` step.

### On Unix-like systems

Download [NGINX](http://nginx.org) and nginx-http-flv-module.

Uncompress them.

cd to NGINX source directory & run this:

#### Compile the module into [NGINX](http://nginx.org)

    ./configure --add-module=/path/to/nginx-http-flv-module
    make
    make install

or

#### Compile the module as a dynamic module

    ./configure --add-dynamic-module=/path/to/nginx-http-flv-module
    make
    make install

#### Note

If the module is compiled as a dynamic module, the [NGINX](http://nginx.org) version **MUST** be equal to or greater than 1.9.11.

## Usage

For details of usages of [nginx-rtmp-module](https://github.com/arut/nginx-rtmp-module), please refer to [README.md](https://github.com/arut/nginx-rtmp-module/blob/master/README.md).

### Publish

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

#### Note

* Some legacy versions of [FFmpeg](http://ffmpeg.org) 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.

### Play

#### via HTTP-FLV

    http://example.com[:port]/dir?[port=xxx&]app=appname&stream=streamname

#### Note

* If [ffplay](http://www.ffmpeg.org/ffplay.html) 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](https://github.com/Bilibili/flv.js) is used to play the stream, make sure that the published stream is encoded properly, for [flv.js](https://github.com/Bilibili/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.

#### Example

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

#### Note

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.

#### via RTMP

    rtmp://example.com[:port]/appname/streamname

#### via HLS

    http://example.com[:port]/dir/streamname.m3u8

#### via DASH

    http://example.com[:port]/dir/streamname.mpd

## Example nginx.conf

### Note

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](https://blogs.msdn.microsoft.com/commandline/2017/12/19/af_unix-comes-to-windows) 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](https://github.com/arut/nginx-patches/blob/master/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 1st_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](http://nginx.org) 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;
            ...
        }
    }
