Auto-Generate Blog & AI Image from YouTube Videos with Dumpling AI & GPT-4o

### 🎥 From Video Upload to Blog Prompt

This part of the workflow starts when a new video is added to a designated Google Drive folder. It downloads the video and converts it into base64 format. That base64 video is then sent to Dumpling AI’s `extract-video` endpoint, which transcribes the entire audio content. The transcription is passed to GPT-4o, which writes a full blog post and also creates a descriptive image prompt based on the video's message.
