Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. It provides constructs that enable clear programming on both small and large scales. In July 2018, Van Rossum stepped down as the leader in the language community after 30 years.
Python features a dynamic type system and automatic memory management. It supports multiple programming paradigms, including structured (particularly, procedural), object-oriented, and functional programming. Python is often described as a “batteries included” language due to its comprehensive standard library.
Python interpreters are available for many operating systems. CPython, the reference implementation of Python, is open-source software and has a community-based development model, as do nearly all of its variant implementations. Python and CPython are managed by the non-profit Python Software Foundation.
In this blog post, we will be discussing how to generate a YouTube video with Python. We will be using the YouTube Data API to fetch the required information and then use the Python Imaging Library (PIL) to generate the video.
The YouTube Data API allows developers to access YouTube’s vast video catalog and perform a variety of operations, such as searching for videos, retrieving video information, and uploading videos. The API can be used to fetch the required information for our video, such as the video title, description, thumbnail, etc.
The Python Imaging Library (PIL) is a free and open-source library for manipulating images in a wide variety of formats. We will be using this library to generate the video frames for our YouTube video.
We will also be using the FFmpeg library to encode the video frames into a format that YouTube can understand.
The first step is to fetch the required information from the YouTube Data API. We will need to create a developer key to use the API. You can find more information on how to do this here:
https://developers.google.com/youtube/v3/getting-started
Once you have your developer key, you can use the following code to fetch the required information for our video:
video_id = 'kfWvltE5RzM'
client = youtube_client.YoutubeClient(developer_key)
video_info = client.get_video_info(video_id)
title = video_info['snippet']['title']
description = video_info['snippet']['description']
thumbnail_url = video_info['snippet']['thumbnails']['default']['url']Next, we need to download the thumbnail image for our video. We will use the Python requests library to do this:
import requests
thumbnail_response = requests.get(thumbnail_url)
with open('thumbnail.jpg', 'wb') as f:
f.write(thumbnail_response.content)Now that we have the thumbnail image, we can use the PIL library to generate the video frames. We will first create a list of images, each containing a frame of the video. The number of frames will depend on the length of the video and the desired frame rate.
frames = []
for i in range(0, len(video_info['items'])):
frame = Image.new('RGB', (1280, 720))
draw = ImageDraw.Draw(frame)
draw.text((10, 10), title, (255, 255, 255))
draw.text((10, 30), description, (255, 255, 255))
draw.rectangle([(10, 50), (1270, 710)], fill=(0, 0, 0))
frames.append(frame)Finally, we need to encode the video frames into a format that YouTube can understand. We will use the FFmpeg library to do this.
import subprocess
video_filename = 'video.mp4'
subprocess.call(['ffmpeg', '-framerate', '24', '-i',
'thumbnail.jpg'] + frames + [video_filename])That’s it! You should now have a video file that you can upload to YouTube.
Anyways, I’ve also created a Cash Cow YouTube channel with Python Automation. My python program daily uploads a video automatically.
