# Emby Thumbnail Generator
|
|
|
|
A self-hosted web UI that generates landscape thumbnails from your Emby library posters. Uses AI-powered subject extraction (rembg/U2-Net, runs entirely locally) to isolate characters from poster art, then composites them into widescreen thumbnails with customisable layouts.
|
|
|
|
## What it does
|
|
|
|
1. Connects to your Emby server via API
|
|
2. Search/browse your movie and TV library
|
|
3. Pulls the poster for a selected item
|
|
4. Extracts the subject (person/character) using rembg (offline, no external API)
|
|
5. Generates a landscape thumbnail with the subject positioned to one side and the title on the other
|
|
6. Optionally pushes the generated thumbnail back to Emby as a custom Thumb image
|
|
|
|
## Templates
|
|
|
|
- **Subject Left, Text Right** — character on the left, title text on the right
|
|
- **Subject Right, Text Left** — character on the right, title text on the left
|
|
- **Subject Center, Text Overlay** — character centered with title overlaid
|
|
|
|
## Background Modes
|
|
|
|
- **Auto Gradient** — samples dominant colours from the poster and creates a dark gradient
|
|
- **Blurred Poster** — darkened, heavily blurred version of the original poster
|
|
- **Solid Colour** — pick your own background colour
|
|
|
|
## Setup
|
|
|
|
### Docker (recommended)
|
|
|
|
1. Edit `docker-compose.yml` with your Emby details:
|
|
```yaml
|
|
environment:
|
|
- EMBY_URL=http://192.168.1.x:8096
|
|
- EMBY_API_KEY=your-api-key
|
|
```
|
|
|
|
2. Build and run:
|
|
```bash
|
|
docker compose up -d --build
|
|
```
|
|
|
|
3. Open `http://localhost:8500`
|
|
|
|
### Manual
|
|
|
|
1. Install dependencies:
|
|
```bash
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
2. Set environment variables:
|
|
```bash
|
|
export EMBY_URL=http://192.168.1.x:8096
|
|
export EMBY_API_KEY=your-api-key
|
|
```
|
|
|
|
3. Run:
|
|
```bash
|
|
python app.py
|
|
```
|
|
|
|
4. Open `http://localhost:8500`
|
|
|
|
## Getting your Emby API Key
|
|
|
|
1. Open Emby Dashboard → Advanced → API Keys
|
|
2. Click "New API Key"
|
|
3. Give it a name (e.g. "Thumb Generator")
|
|
4. Copy the key
|
|
|
|
## Notes
|
|
|
|
- First generation will be slower as rembg downloads the U2-Net model (~170MB)
|
|
- The model runs entirely offline after first download — no data leaves your network
|
|
- Generated thumbnails are cached in the `cache/` directory
|
|
- Works with both movies and TV series
|
|
- The "Apply to Emby" button sets the generated image as the item's Thumb image type
|
|
|
|
## Tech Stack
|
|
|
|
- **Backend:** Python, FastAPI, Pillow, rembg (U2-Net)
|
|
- **Frontend:** Vanilla HTML/CSS/JS
|
|
- **Deployment:** Docker
