-# Livekit-Uploader
+# Meetling Livekit Recording Uploader
 
+This containerized utility monitors a directory for new `.mp4` files, splits them into chunks, and uploads each chunk to a specified endpoint. It is intended for use with the Meetling Livekit recording system.
+
+---
+
+## 📦 Features
+
+- 📁 Watches the `/out` directory for new `.mp4` files
+- ✂️ Splits files into configurable chunk sizes
+- 📤 Uploads chunks via HTTP with bearer token authorization
+- 🐳 Lightweight Alpine-based Docker image
+
+---
+
+## ⚙️ Environment Variables
+
+| Variable      | Default                                   | Description                                |
+|---------------|-------------------------------------------|--------------------------------------------|
+| `CHUNK_SIZE`  | `1048576` (1 MiB)                         | Size of each chunk in bytes                |
+| `UPLOAD_URL`  | `http://localhost:8000/recording/upload`  | Upload endpoint URL                        |
+| `AUTH_TOKEN`  | `verySecretToken`                         | Bearer token for authentication            |
+

+
+## 🚀 Usage
+
+### 1. Build the Docker image
+
+```sh
+docker build -t meetling-uploader --build-arg VERSION=1.0.0 .
+```
+
+### 2. Run the container
+
+```sh
+docker run -v /your/output/directory:/out meetling-uploader
+```
+
+> Replace `/your/output/directory` with the directory containing your `.mp4` recordings.
+
+---
+
+## 🔄 Upload Process
+
+Once a `.mp4` file is completely written to `/out`, the script:
+
+1. Verifies the file exists.
+2. Calculates file size.
+3. Splits the file into chunks based on `CHUNK_SIZE`.
+4. Uploads each chunk using `curl`.
+
+Each upload includes the following multipart form fields:
+
+- `recording_id`: Filename without `.mp4`
+- `chunk_index`: Index of the chunk (starting from 0)
+- `total_chunks`: Total number of chunks
+- `file`: The actual chunk
+
+---
+
+## 🐳 Dockerfile Overview
+
+The image uses `alpine:3.20` and installs:
+
+- `inotify-tools` (for file system event watching)
+- `curl` (for HTTP requests)
+- `coreutils` (for `stat` and `dd` utilities)
+
+The script is located at `/inotify.sh` and is executed when the container starts.  
+It runs as the non-privileged user `nobody` for security.
