Description#

OmniCast Studio is a local Node.js application that provides a multi-modal pipeline for processing text, audio, and video into podcast scripts and social media assets. It exposes a set of local API endpoints to orchestrate these tasks.

Setup Requirements#

This application requires the following environment variables to be set in a local .env file:

• GEMINI_API_KEY: Required for text analysis, translation, and script drafting.
• OPENAI_API_KEY: Required for audio transcription and synthesis.
• PORT: Defaults to 7860.

System Requirements:

• Node.js >= 20.0.0
• FFmpeg installed and available in the system PATH.

API Endpoints (Localhost:7860)#

The service runs strictly on http://127.0.0.1:7860. The following endpoints are available:

1. Media Ingestion#

• Endpoint: POST /api/ingest
• Purpose: Accepts a URL or file upload. It extracts the text, detects the language, and translates it to English if necessary.

2. Script Drafting#

• Endpoint: POST /api/draft-script
• Purpose: Utilizes the ingested text to format a conversational, two-host script suitable for audio synthesis.

3. Audio Synthesis#

• Endpoint: POST /api/synthesize
• Purpose: Converts the drafted script into a final audio file using TTS services.

4. LinkedIn Packaging#

• Endpoint: POST /api/generate-linkedin
• Purpose: Generates a social media text post and renders a looping MP4 video of the podcast cover art with the synthesized audio.
