Car-eye-http-flv-module implements the FLV Live function of Nginx-rtmp-mudule http mode

Nginx-rtmp-mudule rtmp is an excellent car-eye-http-flv-module is a streaming media server modified on Nginx-rtmp-mudule rtmp basis, in addition to support Flash player, Players that are now common are also supported. A perfect way to achieve the HTTP mode of FLV Live Function.

This article briefly introduces the main functions and use of the module:

Function

• All features provided by Nginx-rtmp-module.

• FLV live stream playback based on HTTP Protocol.

• GOP cache, reducing playback latency (h. + video and AAC audio).

• Transfer-Encoding: chunkedhttp reply with support Mode.

• Configuration items can be omitted from the server block of the rtmp configuration listen .

• Support for Virtual Hosts.

Supported Systems

• Linux (recommended)/freebsd/macos/windows (limited).

Supported players

• VLC (rtmp & http-flv)/obs (rtmp & http-flv)/jw Player (rtmp)/flv.js (http-flv).

Depend on

• On Unix-like systems, GNU make is required to invoke the compiler to compile the Software.

• On Unix-like systems, the need for gcc/on Windows requires msvc for compiling software.

• On a unix-like system, gdb is required for debugging software (optional).

• FFmpeg, which is used to publish media streams.

• VLC player (recommended) for playing media streaming.

• If Nginx wants to support regular expressions, the Pcre library is Required.

• If Nginx wants to support encrypted access, the OpenSSL library is Required.

• If Nginx is to support compression, the Zlib library is Required.

Create on Windows

To compile the steps please refer to building nginx on the Win32 platform with Visual C, do not forget to Run configure script add in step --add-module=/path/to/nginx-http-flv-module .

On Unix-like Systems

Download Nginx and Nginx-http-flv-module.

Unzip them to a certain path.

Open the Nginx source code path and Execute:

Compile the module into Nginx

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

Compiling a module into a dynamic module

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

Attention

If the module is compiled into a dynamic module, then the version number of Nginx must be greater than or equal to 1.9.11.

Release

ffmpeg -re -i example.mp4 -vcodec copy -acodec copy -f flv rtmp://example.com[:port]/appname/streamname

appnameUsed to match the application Block in the RTMP configuration block (see below for more details).

streamnamecan be arbitrarily specified.

The default port for Rtmp is 1935 and must be specified if you want to use a different port :port .

Play (HTTP)

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

The parameters are dir used to match the location block in the HTTP configuration block (see below for more details).

The HTTP default port is 80, which must be specified if other ports are used :port .

The default port for RTMP is 1935, which must be specified if other ports are used port=xxx .

Parameters are app used to match the application block, but if the request app appears in more than one server block, and the server blocks have the same address and port configuration, server_name the Configure the item to differentiate which application block is requested, otherwise the first application block will be Matched.

Parameters stream are used to match the streamname of the publishing Stream.

Example

Assume that the http configuration items in the configuration block listen are:

http {    ...    server {        listen 8080; #不是默认的80端口        ...        location /live {            flv_live on;        }    }}

The rtmp configuration items in the configuration block listen are:

rtmp {    ...    server {        listen 1985; #不是默认的1935端口        ...        application myapp {            live on;        }    }}

Then the http-based playback URL is:

http://example.com:8080/live?port=1985&app=myapp&stream=mystream

Attention

If you are using HTTP version 1.1 (http/1.1), The chunked_transfer_encoding configuration entry is turned on by Default.

Because some players do not support HTTP block transfers, It is best to specify in the location specified in this case flv_live on; chunked_transfer_encoding off , otherwise playback will Fail.

nginx.conf Example Note

Configuration Items rtmp_auto_push , rtmp_auto_push_reconnect and rtmp_socket_dir does not work on windows, except for Windows 10 17063 and later versions, because the multi-process mode relay requires support for UNIX domain sockets, see UNIX domain socket on Windows 10.
