Proof of Concept - Azure Blob media content optimization

About

This project is a proof of concept to demonstrate how to optimize media content stored in Azure Blob Storage.

There are several workflows available:

• download: will download the files from the source container to a local folder using parallel requests and avoiding big files like videos. This criteria can be changed in the config file. This workflow will also create a metadata.json file that can be used to explorer the blob files
• resize: will alert you from using huge images based on a threshold that can be modified in the config file.
• optimize: will optimize the files in a subfolder. It will print a report with the comparison between the original and the optimized files.
• upload: will upload the optimized files to a destination container. It will overwrite the previous files.
