This code binds a live stream to a YouTube broadcast using the YouTube API, utilizing functions to import necessary modules and notebooks, authorize API credentials, retrieve broadcast and stream information, and execute the binding request. The bind_stream_to_broadcast function returns the stream information and broadcast ID, and is exported for use in other modules.

Run example

npm run import -- "bind youtube stream"

bind youtube stream

import_notebook("list broadcasts",
"globals("))
import_notebook("list live stream",
"globals("))
from googleapiclient.discovery import build

def bind_stream_to_broadcast():

    credentials = youtube_authorize()

    broadcast_id = list_broadcasts()[0]["id"]

    stream = list_livestream()

    print(stream['cdn']['ingestionInfo']['streamName'])

    # Build the YouTube API client
    youtube = build("youtube", "v3", credentials=credentials)

    request = youtube.liveBroadcasts().bind(
        id=broadcast_id,
        part="id,contentDetails",
        streamId=stream["id"]
    )
    response = request.execute()
    print("✅ Stream successfully bound to broadcast:", response)
    
    return stream, broadcast_id

__all__ = {
    "bind_stream_to_broadcast": bind_stream_to_broadcast
}

stream, broadcast_id = bind_stream_to_broadcast()

Code Breakdown

Importing Required Modules and Notebooks

import_notebook("list broadcasts", globals())
import_notebook("list live stream", globals())
from googleapiclient.discovery import build

• The import_notebook function is used to import contents from notebooks, and the globals() function is used to access the global scope. This is likely used to dynamically import functions from notebooks named "list broadcasts" and "list live stream".
• The googleapiclient.discovery module is imported, specifically the build function, which is used to create a client instance for the YouTube API.

Binding Stream to Broadcast

def bind_stream_to_broadcast():

• This function takes no arguments and returns no values.

Authorizing YouTube API Credentials

credentials = youtube_authorize()

• The youtube_authorize function is called to obtain YouTube API credentials.

Getting Broadcast ID and Stream Information

broadcast_id = list_broadcasts()[0]["id"]
stream = list_livestream()
print(stream['cdn']['ingestionInfo']['streamName'])

• The list_broadcasts function is called to retrieve a list of broadcasts, and the ID of the first broadcast is extracted.
• The list_livestream function is called to retrieve live stream information, and the stream name is printed.

Building YouTube API Client and Binding Stream to Broadcast

youtube = build("youtube", "v3", credentials=credentials)

request = youtube.liveBroadcasts().bind(
    id=broadcast_id,
    part="id,contentDetails",
    streamId=stream["id"]
)
response = request.execute()
print("✅ Stream successfully bound to broadcast:", response)

• A YouTube API client is created using the build function, passing the service name, API version, and credentials.
• The bind method of the liveBroadcasts resource is used to bind the stream to the broadcast, passing the broadcast ID, the id and contentDetails parts, and the stream ID.
• The execute method is called to execute the request, and the response is printed.

Returning Stream and Broadcast ID

return stream, broadcast_id

• The function returns the stream information and the broadcast ID.

Exporting Function

__all__ = {
    "bind_stream_to_broadcast": bind_stream_to_broadcast
}

• The bind_stream_to_broadcast function is exported, making it available for import in other modules.
