# KV-Download (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, TikTok, Instagram, 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.

### Build Your Own Image

```bash
docker build -t git.khoavo.myds.me/vndangkhoa/kv-download:v1 --platform linux/amd64 .
docker push git.khoavo.myds.me/vndangkhoa/kv-download:v1
```

## Docker Environment Variables
* `MR_DOWNLOAD_DIR` where videos are saved. Defaults to `/download`
* `MR_PROXY` will pass the value to yt-dlp with the `--proxy` argument. Defaults to empty

## File Structure

After downloading videos, files are organized as follows:
```
/download/
├── <hash>/
│   └── <video-id>.mp4        # Video files
└── json/
    └── <video-id>.info.json   # Metadata files (separate folder)
```

# 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://127.0.0.1:9292/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.
