Generate Media Info

This set of scripts and corresponding docker file will process all media files within a folder structure recursively and do one of the following:

• create a mediainfo.json file for each one found and then create a single file that combines them all into one (to simplify processing)
• process the mediainfo.json file that was created and extract a few key properties to simplify reporting and save this to mediainfo.summary.josn

Ways to run

There are two ways to run the script, one is via installation (pip module) and the3 other is via docker.

Installation

First step is to install the module via pip

pip install mediainfo-generator

Then you can run it like this

mediainfo-generator --path.data /mnt/video

Docker

To Generate media info files and consolidated mediainfo.json file run the following command (after building the container)

docker run --rm -v /path/to/your/video/files:/data media-info --path.data /data

Note: You can pass an optional argument if you want to change the root folder in the container to scan (defaults to /data)

Command Line Arguments

Build

git clone https://github.com/ravensorb/mediainfo-generator.git

cd mediainfo-generator/docker
docker build -t media-info .
