-# KV-Tube
+# KV-Tube v3.0
-**A Distraction-Free, Privacy-Focused YouTube Client**
+
-
+> A lightweight, privacy-focused YouTube frontend web application with AI-powered features.
-> [!NOTE] 
+
-> Designed for a premium, cinematic viewing experience.
+KV-Tube removes distractions, tracking, and ads from the YouTube watching experience. It provides a clean interface to search, watch, and discover related content without needing a Google account.
-
+
-KV-Tube removes the clutter and noise of modern YouTube, focusing purely on the content you love. It strictly enforces a horizontal-first video policy, aggressively filtering out Shorts and vertical "TikTok-style" content to keep your feed clean and high-quality.
+## 🚀 Key Features (v3)
-
+
-### 🚀 **Key Features (v2.0)**
+- **Privacy First**: No tracking, no ads.
-
+- **Clean Interface**: Distraction-free watching experience.
-*   **🚫 Ads-Free & Privacy-First**: Watch without interruptions. No Google account required. All watch history is stored locally on your device (or self-hosted DB).
+- **Efficient Streaming**: Direct video stream extraction using `yt-dlp`.
-*   **📺 Horizontal-First Experience**: Say goodbye to "Shorts". The feed only displays horizontal, cinematic content.
+- **AI Summary (Experimental)**: Generate concise summaries of videos (Currently disabled due to upstream rate limits).
-*   **🔍 Specialized Feeds**:
+- **Multi-Language**: Support for English and Vietnamese (UI & Content).
-    *   **Tech & AI**: Clean feed for gadget reviews and deep dives.
+- **Auto-Update**: Includes `update_deps.py` to easily keep core fetching tools up-to-date.
-    *   **Trending**: See what's popular across major categories (Music, Gaming, News).
+
-    *   **Suggested for You**: Personalized recommendations based on your local watch history.
+## 🛠️ Architecture Data Flow
-*   **🧠 Local AI Integration**:
+
-    *   **Auto-Captions**: Automatically enables English subtitles.
+```mermaid
-    *   **AI Summary**: (Optional) Generate quick text summaries of videos locally.
+graph TD
-*   **⚡ High Performance**: Optimized for speed with smart caching and rate-limit handling.
+    User[User Browser]
-*   **📱 PWA Ready**: Install on your phone or tablet with a responsive, app-like interface.

-## 🛠️ Deployment
+
-
+    User -- "1. Search / Watch Request" --> Server
-You can run KV-Tube easily using Docker (recommended for NAS/Servers) or directly with Python.
+    Server -- "2. Extract Video Metadata" --> YTDLP
-
+    YTDLP -- "3. Network Requests (Cookies Optional)" --> YouTube
-### Option A: Docker Compose (Recommended)
+    YouTube -- "4. Raw Video/Audio Streams" --> YTDLP
-Ideal for Synology NAS, Unraid, or casual servers.
+    YTDLP -- "5. Stream URL / Metadata" --> Server
-
+    
-1.  Create a folder `kv-tube` and add the `docker-compose.yml` file.
+    subgraph Transcript System [Transcript System (Deferred)]
-2.  Run the container:
+        Server -.-> YTFetcher
-    ```bash
+        YTFetcher -.-> YouTube
-    docker-compose up -d
+        YTFetcher -- "No Transcript (429)" -.-> Server
-    ```
+    end
-3.  Access the app at: **http://localhost:5011**

+# Media Roller
+A mobile friendly tool for downloading videos from social media.
+The backend is a Golang server that will take a URL (YouTube, Reddit, Twitter, etc),
+download the video file, and return a URL to directly download the video. The video will be transcoded to produce a single mp4 file.
+
+This is built on [yt-dlp](https://github.com/yt-dlp/yt-dlp). yt-dlp will auto update every 12 hours to make sure it's running the latest nightly build.
+
+Note: This was written to run on a home network and should not be exposed to public traffic. There's no auth.
+
+![Screenshot 1](https://i.imgur.com/lxwf1qU.png)
+
+![Screenshot 2](https://i.imgur.com/TWAtM7k.png)
+
+
+# Running
+Make sure you have [yt-dlp](https://github.com/yt-dlp/yt-dlp) and [FFmpeg](https://github.com/FFmpeg/FFmpeg) installed then pull the repo and run:
+```bash
+./run.sh
+```
+Or for docker locally:
+```bash
+ ./docker-build.sh
+ ./docker-run.sh
+```
+
+With Docker, published to both dockerhub and github.
+* ghcr: `docker pull ghcr.io/rroller/media-roller:master`
+* dockerhub: `docker pull ronnieroller/media-roller`
+
+See:
+* https://github.com/rroller/media-roller/pkgs/container/media-roller
+* https://hub.docker.com/repository/docker/ronnieroller/media-roller
+
+The files are saved to the /download directory which you can mount as needed.
+
+## Docker Environemnt Variables
+* `MR_DOWNLOAD_DIR` where videos are saved. Defaults to `/download`
+* `MR_PROXY` will pass the value to yt-dlp witht he `--proxy` argument. Defaults to empty
+
+# API
+To download a video directly, use the API endpoint:
+
+```
+/api/download?url=SOME_URL
+```
+
+Create a bookmarklet, allowing one click downloads (From a PC):
+
+```
+javascript:(location.href="http://127.0.0.1:3000/fetch?url="+encodeURIComponent(location.href));
+```
+
+# Integrating with mobile
+After you have your server up, install this shortcut. Update the endpoint to your server address by editing the shortcut before running it. 
+
+https://www.icloud.com/shortcuts/d3b05b78eb434496ab28dd91e1c79615

+# Unraid
+media-roller is available in Unraid and can be found on the "Apps" tab by searching its name.
