## What it is
A tutorial and tool for indiscriminately extracting videos that use MediaSource (MSE) playback, by intercepting video segments at the final loading step via Chrome DevTools console injection or a Tampermonkey userscript. It captures audio and video segments, then downloads them for merging or playback with a dedicated player.

## Use cases
- download videos from websites that use MSE streaming
- extract m3u8-protected video segments for offline viewing
- capture video and audio streams playing in the browser
- bypass complex video encryption by intercepting at playback stage
- speed up video capture with 10x playback

## When to choose
- you need a universal, no-setup-required way to capture MSE-based streaming video
- you want to avoid dealing with video encryption and decryption directly
- you prefer a passive capture approach that works across many sites

## When to avoid
- you need fully automated, hands-off video downloading
- the site does not use MediaSource playback technology
- you cannot use Chrome DevTools or browser extensions
- you want to download DRM-protected content (this is not a cracking tool)
