New Meta Data Add-on for nanoStream

nanoStream Live Encoding Software Platforms now supporting meta data transport injection

Our nanoStream SDKs, Apps and browser plugins now can be extended for sending any kind of meta data information to streaming server backends and players.
Based on a simple JSON API, any kind of object can be embedded into live streams.
Examples are: sending cue points, custom events, ad inserts, any kind of meta data.
Available in nanoStream Version 3.6 on Windows, MacOS, Desktop and Browsers and Mobile Devices (iOS/Android).

Example usage to inject RTMP meta data

  • Sending a RTMP Cue Point

    // { name: cuepoint, time: 0.5 }
    data = ' "name": "name1", "time": "0.5", "type": "type1", "parameters": { "p1": "v1", "p2": "v2" }';
    nanoStream.SendMetadata("onCuePoint", data, "", 0);

  • How To Use Tunneling for Firewall Protected Streaming Setups

    nanoStream3 supports RTMPT, the tunneling protocol of RTMP,
    including automatic Proxy detection.

    The URL should then be similar to this:


    The port should probably be 80, dependent on the corporate firewall and streaming server setup.

    Please note that RTMPT Tunneling is a workaround
    using the firewall-accepted HTTP protocol.
    This requires a protocol overhead, so plain RTMP is preferred.

    For using Firewalls, it might work to stream plain RTMP over port 80, like this:


    If this fails, use RTMPT.

    How To Stream To Mobile Devices (iPhone, iOS) with nanoStream and Wowza

    Streaming to Mobile Devices is simple with nanoStream.
    iOS requires H.264 video and AAC audio, which is used by default in nanoStream.

    Encoder Settings

    Video and Audio format should be H.264 and AAC.
    Video Encoding Profile can either be “Baseline” or “Main”, dependent on the playback device support.
    In earlier iOS revisions, only “Baseline” profile worked. Since iOS 3, also Main Profile should work.

    Output Streaming URL

    Live Playback in iOS devices requires HLS support (“HTTP Live Streaming”). Wowza supports delivering with HLS with an RTMP upstream.

    So the encoder can run in RTMP mode and let the Wowza server to the protocol transcoding to HLS.

    Encoder URL: Live URL + Stream Name:




    Playback URL on iOS Devices:


    Note: this might require additional configuration on the streaming server. See the Wowza or Adobe documentation for further help.
