Video transcoding solution converting live webcam streams to HLS (HTTP Live Streaming) that browsers and players can consume. It also supports often needed requirements like watermarking and scaling the video streams.

Requirements

• Go (for development only)
• ffmpeg
  • Install latest release for macOS

    brew install ffmpeg

  • Install latest release for Linux kernels >= v3.2.0

    wget https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-amd64-static.tar.xz
    tar xvf ffmpeg-release-amd64-static.tar.xz
    sudo mv ffmpeg-*-amd64-static/ff* /usr/local/bin/

Defining Streams

Streams are defined in a single YAML file following the format:

- name: <Stream Name> (required)
  url: <URL of the IP camera> (required)
  rtsp_transport: <"tcp" or "udp"> (optional, "tcp" is default)
  scale: <width:height> (optional)
  watermarks:
    - file: <path to the image> (required)
      opacity: <0.1 - 1> (required)
      position: <"top-left" or "center" or "bottom-right"> (required)

Definitions will be transcoded and the main streaming playlist (video) will each be served over HTTP at:

http://localhost:53030/streaming/<Stream Name>/playlist.m3u8

Web Player

Since only Apple products natively support HLS, you're recommended to use HLS.js as an open-source browser player.
