### Features
* 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
### Build
cd to NGINX source directory & run this:
    ./configure --add-module=/path/to/nginx-rtmp-module
    make
    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
[Read more about debug log](https://github.com/arut/nginx-rtmp-module/wiki/Debug-log)
### Windows limitations
Windows support is limited. These features are not supported
* execs
* static pulls
* auto_push
### RTMP URL format
    rtmp://rtmp.example.com/app[/name]
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 127.0.0.1;
                deny publish all;
                #allow play all;

            application big {
