MaFFiN

MaFFiN is a Node.JS server that implements the Media Fragment W3C Recommendation.

It supports temporal (npt) and track fragment, both in hash and query format.

See my slides.

Requirements

• A recent version of Node.js
• A MongoDb database running on your machine (or on a reachable host)
• A recent build of ffmpeg, that includes ffprobe

Install

Please install dependencies with

npm install

You need also to setup the file config.json:

{
    "app_options": {
        "input_dir": "D:\\video\\",           \\ input video path
        "output_dir": "D:\\video\\tmp\\",     \\ temporary output video path
        "mongo_host": "localhost",            \\ host where MongoDb is running
        "mongo_port": 27017,                  \\ port where MongoDb is running
        "frag_ttl": 60                        \\ how much time output video must be deleted after (in seconds)
    },
    "ffmpeg_path": {
        "ffmpeg": "C:\\ffmpeg\\bin\\ffmpeg.exe",  \\ ffmpeg build path
        "ffprobe": "C:\\ffmpeg\\bin\\ffprobe.exe" \\ ffprobe build path
    },
    "debug": true                             \\ if false, it hides some logs on Node.js console
}

Please make sure that input_dir and output_dir exist on your filesystem.
