YouTube Video Description Updater

Updates the YouTube video description with the latest Baidu Wangpan share link and retrieval code, using the YouTube Data API v3 (no browser automation needed).

Files

• Baidu share registry: tools/baidu/shares.json — read latest URL + 提取码
• Video info: tools/youtube/video_info.txt — stores video ID
• Description template: tools/youtube/description_template.txt — template with {{BAIDU_SHARE_SECTION}} placeholder
• OAuth credentials: tools/youtube/client_secret.json — Google OAuth2 credentials
• Cached token: tools/youtube/token.json — cached OAuth token (auto-generated after first auth)
• Update script: tools/youtube/update_description.py — Python script for API calls

Prerequisites

• google-api-python-client and google-auth-oauthlib installed (already available)
• Google Cloud project with YouTube Data API v3 enabled
• OAuth2 credentials downloaded to tools/youtube/client_secret.json
• Latest Baidu share link in tools/baidu/shares.json

First-Time Setup

If tools/youtube/client_secret.json doesn't exist:

1. Go to https://console.cloud.google.com/
2. Create a project (or select existing)
3. Enable "YouTube Data API v3"
4. Go to Credentials → Create Credentials → OAuth 2.0 Client ID
5. Application type: Desktop app
6. Download the JSON → save as tools/youtube/client_secret.json
7. Under OAuth consent screen, add the user's Google account as a test user

First run will open a browser for OAuth consent. After that, the token is cached.

Workflow

Step 1: Generate description from template

Same pattern as bilibili-updater:

import json
with open('tools/youtube/description_template.txt', 'r', encoding='utf-8') as f:
    template = f.read()
with open('tools/baidu/shares.json', 'r', encoding='utf-8') as f:
    latest = json.load(f)['uploads'][0]
baidu = '百度网盘: ' + latest['url'] + '\n提取码: ' + latest['retrieval_code']
desc = template.replace('{{BAIDU_SHARE_SECTION}}', baidu).rstrip()

Step 2: Update via YouTube API

Run the update script:

python tools/youtube/update_description.py --video-id VIDEO_ID --description "new description"

Or call the API directly:

from google.oauth2.credentials import Credentials
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build
import json, os

SCOPES = ['https://www.googleapis.com/auth/youtube']
TOKEN_PATH = 'tools/youtube/token.json'
SECRET_PATH = 'tools/youtube/client_secret.json'

def get_youtube_service():
    creds = None
    if os.path.exists(TOKEN_PATH):
        creds = Credentials.from_authorized_user_file(TOKEN_PATH, SCOPES)
    if not creds or not creds.valid:
        flow = InstalledAppFlow.from_client_secrets_file(SECRET_PATH, SCOPES)
        creds = flow.run_local_server(port=0)
        with open(TOKEN_PATH, 'w') as f:
            f.write(creds.to_json())
    return build('youtube', 'v3', credentials=creds)

def update_description(video_id, new_description):
    yt = get_youtube_service()
    # Get current video details (need snippet for update)
    resp = yt.videos().list(part='snippet', id=video_id).execute()
    if not resp['items']:
        raise Exception(f'Video {video_id} not found')
    snippet = resp['items'][0]['snippet']
    snippet['description'] = new_description
    # categoryId is required for update
    yt.videos().update(
        part='snippet',
        body={'id': video_id, 'snippet': snippet}
    ).execute()
    return snippet['title']

Step 3: Report to user

Updated YouTube video description
Video: [title]
Video ID: [id]
New Baidu link: [url]
提取码: [code]

Notes

• OAuth token expires periodically — the script auto-refreshes it
• YouTube API has a daily quota (10,000 units). A video update costs 50 units — plenty of headroom
• The credentials files are gitignored (tools/ is already in .gitignore)
• Video descriptions on YouTube have a 5000 character limit
