  • RTMP/HLS/MPEG-DASH live streaming

  • RTMP Video on demand FLV/MP4, playing from local filesystem or HTTP

  • Stream relay support for distributed streaming: push & pull models

  • Recording streams in multiple FLVs

  • H264/AAC support

  • Online transcoding with FFmpeg

  • HTTP callbacks (publish/play/record/update etc)

  • Running external programs on certain events (exec)

  • HTTP control module for recording audio/video and dropping clients

  • Advanced buffering techniques to keep memory allocations at a minimum level for faster streaming and low memory footprint

  • Proved to work with Wirecast, FMS, Wowza, JWPlayer, FlowPlayer, StrobeMediaPlayback, ffmpeg, avconv, rtmpdump, flvstreamer and many more

  • Statistics in XML/XSL in machine- & human- readable form

  • Linux/FreeBSD/MacOS/Windows


cd to NGINX source directory & run this:

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

Several versions of nginx (1.3.14 - 1.5.0) require http_ssl_module to be added as well:

./configure --add-module=/path/to/nginx-rtmp-module --with-http_ssl_module

For building debug version of nginx add --with-debug

./configure --add-module=/path/to-nginx/rtmp-module --with-debug

Windows limitations

Windows support is limited. These features are not supported

  • execs
  • static pulls
  • auto_push

RTMP URL format


app - should match one of application {} blocks in config

name - interpreted by each application can be empty

Multi-worker live streaming

Module supports multi-worker live streaming through automatic stream pushing to nginx workers. This option is toggled with rtmp_auto_push directive.

Example nginx.conf

rtmp {

    server {

        listen 1935;

        chunk_size 4000;

        # TV mode: one publisher, many subscribers
        application mytv {

            # enable live streaming
            live on;

            # record first 1K of stream
            record all;
            record_path /tmp/av;
            record_max_size 1K;

            # append current timestamp to each flv
            record_unique on;

            # publish only from localhost
            allow publish;
            deny publish all;

            #allow play all;

        # Transcoding (ffmpeg needed)
        application big {
            live on;

            # On every pusblished stream run this command (ffmpeg)
            # with substitutions: $app/${app}, $name/${name} for application & stream name.
            # This ffmpeg call receives stream from this application &
            # reduces the resolution down to 32x32. The stream is the published to
            # 'small' application (see below) under the same name.
            # ffmpeg can do anything with the stream like video/audio
            # transcoding, resizing, altering container/codec params etc
            # Multiple exec lines can be specified.

            exec ffmpeg -re -i rtmp://localhost:1935/$app/$name -vcodec flv -acodec copy -s 32x32
                        -f flv rtmp://localhost:1935/small/${name};

        application small {
            live on;
            # Video with reduced resolution comes here from ffmpeg

        application webcam {
            live on;

            # Stream from local webcam
            exec_static ffmpeg -f video4linux2 -i /dev/video0 -c:v libx264 -an
                               -f flv rtmp://localhost:1935/webcam/mystream;

        application mypush {
            live on;

            # Every stream published here
            # is automatically pushed to
            # these two machines

        application mypull {
            live on;

            # Pull all streams from remote machine
            # and play locally
            pull rtmp://;

        application mystaticpull {
            live on;

            # Static pull is started at nginx start

        # video on demand
        application vod {
            play /var/flvs;

        application vod2 {
            play /var/mp4s;

        # Many publishers, many subscribers
        # no checks, no recording
        application videochat {

            live on;

            # the session variables as well as
            # particular call arguments in HTTP POST
            # request

            # Make HTTP request & use HTTP retcode
            # to decide whether to allow publishing
            # from this connection or not
            on_publish http://localhost:8080/publish;

            # Same with playing

            # Publish/play end (repeats on disconnect)
            on_done http://localhost:8080/done;

            # All above mentioned notifications receive
            # standard connect() arguments as well as
            # play/publish ones. If any arguments are sent
            # with GET-style syntax to play & publish
            # these are also included.
            # Example URL:
            #   rtmp://localhost/myapp/mystream?a=b&c=d

            # record 10 video keyframes (no audio) every 2 minutes
            record keyframes;

            # Async notify about an flv recorded
            on_record_done http://localhost:8080/record_done;


        # HLS

        # For HLS to work please create a directory in tmpfs (/tmp/hls here)
        # for the fragments. The directory contents is served via HTTP (see
        # http{} section in config)
        # Incoming stream must be in H264/AAC. For iPhones use baseline H264
        # profile (see ffmpeg example).
        # This example creates RTMP stream from movie ready for HLS:
        # ffmpeg -loglevel verbose -re -i movie.avi  -vcodec libx264
        #    -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
        #    -f flv rtmp://localhost:1935/hls/movie
        # If you need to transcode live stream use 'exec' feature.
        application hls {
            live on;
            hls on;
            hls_path /tmp/hls;

        # MPEG-DASH is similar to HLS

        application dash {
            live on;
            dash on;
            dash_path /tmp/dash;

# HTTP can be used for accessing RTMP stats
http {

    server {

        listen      8080;

        # This URL provides RTMP statistics in XML
        location /stat {
