Yesterday, I discovered how you can enable jsonb in postgres/psycopg2. Today, I experimented around with how to query the data in json columns. There is documentation, but it wasn’t initially clear to me how the different operations worked.

CREATE TABLE json_test (
  id serial primary key,
  data jsonb
);

Need

Convert .mov/.MP4 to .gif

Reason

As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.

This is not limited to developer, anyone has this need can use this method to convert the files.

	#!/usr/bin/python3
	# read, akaze and show

	import cv2
	import multiprocessing

	# Function to read video frames
	def read_video_stream(video_file, frame_queue):
	cap = cv2.VideoCapture(video_file)

	{
	"cmd": ["fpcbuild.bat", "$file"], "quiet": true
	}
