Subject: [PATCH 13/22] Create parser_video.py

README.md
video parser
Python script for extracting images from video files

Basic usage: python3 video_parser.py -i INPUT_DIR -o OUTPUT_DIR

INPUT_DIR is the directory containing video files, INPUT_DIR can also be a zip file
OUTPUT_DIR is where RGB frames are saved
Examples:

To process first 100 frames only:
python3 video_parser.py -i INPUT_DIR -o OUTPUT_DIR -n 100
To flip image:
python3 video_parser.py -i INPUT_DIR -o OUTPUT_DIR --flip
To extract every 5th-frame:
python3 video_parser.py -i INPUT_DIR -o OUTPUT_DIR --skip_frames 5
To delete original data after processing:
python3 video_parser.py -i INPUT_DIR -o OUTPUT_DIR --delete_original
To view all options:
python3 video_parser.py -h
