nginx-rtmp

Live streaming video server for Flash, iOS and Android

Configuration with environment variables

You must set the LIVE_SECRET.

• LIVE_SECRET: Secret token for publishing and statistics.

Other settings are optional and considered experimental. They are under active development and may change or be removed.

The variants option allows for customization beyond the default encoder settings:

• LIVE_VARIANTS_{name}: Represents video and audio transcoding rates and the associated HLS variant bandwidth. These settings will depend on your hardware capability and desired quality. The format is {resolution}:{video_kbps}:{audio_kbps}:{bandwidth_bps}. For full details, see templates/nginx.conf.tmpl and refer to the nginx-rtmp documentation.

The downstreams option allows for copying an incoming RTMP stream to another server, e.g. Facebook.

• LIVE_DOWNSTREAMS_{name}: Corresponds to an RTMP URL that will recieve a copy of the incoming stream. You should only accept a single stream if you use this setting.

The CORS setting allows for cross-origin requests from another frontend server.

• LIVE_CORS: HTTP origin regex to allow CORS on the /hls location.

This image exposes ports 80 for HTTP and 1935 for RTMP.

Example

docker run -e LIVE_SECRET=VERY_SECRET_KEY
           -e LIVE_VARIANTS_LOW=640x480:128:64:192000
           -e LIVE_VARIANTS_MED=640x480:512:128:640000
           -p 80:80 -p 1935:1935 awakening/awakening-nginx-rtmp

Dynamic configuration reloading with etcd

This feature is experimental. It may change or be removed.

If ETCD_URL is provided, configuration is expected to come from the etcd service.

The configuration is the same as above, except they correspond to etcd keys like /live/cors, /live/secret, /live/downstreams/example, etc.

The container will poll for changes every 10 seconds. If changes are detected, nginx will be reloaded with new configuration.

Publish URL

Set your RTMP encoder to publish to rtmp://{your-server}/pub_{PUBLISH_SECRET}/{your-stream-name}.

Player URL

The stream can be viewed at rtmp://{your-server}/player/{your-stream-name}.

HLS

HLS playlists are available at http://{{your-server}/hls/{your-stream-name}.m3u8.

Playback Website

For easy access to the media streams, a custom index.html file containing a video player element (and other resources) can be mounted to the container's /www path.

Statistics

The following resources are available:

• info: General information
• stats: XML of general information

Statistic URLs contain references to the PUBLISH_SECRET, so they are protected. You can visit these protected resources by visiting /p/{token}/{resource-name}, where {token} is set the the result of:

echo -n '{resource-name}{PUBLISH_SECRET}' | openssl md5 -hex
