The code imports necessary libraries, defines constants and two functions (create_livestream and sanitize_filename), and exports the create_livestream function for use. The create_livestream function creates a new live stream on YouTube by authorizing the user, building a YouTube API client, and inserting the live stream details, while the sanitize_filename function replaces invalid characters in a string with underscores.

Run example

npm run import -- "create live stream"

Breakdown of the Code

Importing Libraries

The code starts by importing necessary libraries:

• os: for interacting with the operating system
• re: for regular expression matching operations
• json: not used in this code snippet, but imported for potential use
• google.oauth2.credentials: for handling Google OAuth credentials
• googleapiclient.discovery: for building Google API clients
• import_notebook: a custom function for importing code from a Jupyter notebook (likely used for loading the list live stream function)

Defining Constants

The code defines two constants:

• SCOPES: a list of Google API scopes, specifically for the YouTube API
• HOME_DIR: the home directory of the user, determined by checking environment variables HOME and USERPROFILE

Defining Functions

The code defines two functions:

create_livestream

This function takes a youtube object as input and returns the stream name of the newly created live stream.

1. It authorizes the user using the youtube_authorize function (not shown in this snippet) and gets the credentials.
2. It builds a YouTube API client using the build function from googleapiclient.discovery.
3. It creates a new live stream using the liveStreams().insert method, specifying the stream details (title, description, frame rate, resolution, and ingestion type).
4. It executes the request and returns the stream name.

sanitize_filename

This function takes a string as input and returns a sanitized version of it, replacing any invalid characters with underscores.

Exporting Functions

The code exports the create_livestream function as part of the __all__ dictionary, making it available for import.

Note

The youtube_authorize function is not shown in this snippet and is assumed to handle the authorization process for the YouTube API.
