## What it is
Castor is a Go CLI tool that casts web video to TVs (Chromecast, DLNA) in real time. It extracts streams from web pages via headless Chrome, transcodes with ffmpeg, and can burn in auto-generated subtitles.

## Use cases
- cast a video from a web page to my chromecast
- stream online video to my TV at full quality instead of screen mirroring
- cast a direct stream URL to a DLNA device
- burn subtitles into a video while casting
- cast IPTV streams from the terminal
- extract the hidden video stream from a streaming site

## When to choose
- you want to cast web video to a TV without laggy screen mirroring
- you prefer a terminal-based casting workflow
- you need subtitle burning during casting
- you use Chromecast or DLNA devices

## When to avoid
- the target page blocks automated playback
- you need a GUI casting app
- you want to cast local files only with no web extraction
- you cannot install Chrome and ffmpeg 7.1+ on your machine
