Summary

Just playing around with TileDB and OpenCV with the following goals

1. Understand how to use TileDB
2. Figure out different ways to save images and videos in TileDB
3. Understand video concepts - formats, codecs, compression etc.
4. Perform Read/Write operations on images & videos using TileDB and OpenCV video-writer and compare their performance
