## What it is
h5player is a Tampermonkey userscript that enhances HTML5 video playback on virtually any website with a video tag, including YouTube, TikTok, Bilibili, and Instagram. It adds keyboard shortcuts for variable playback speed, screenshots, picture-in-picture, video zoom, brightness/contrast adjustments, and offline saving of media.

## Use cases
- speed up online tutorials and lectures with variable playback speed
- take screenshots of videos for notes and sharing
- use picture-in-picture to watch video while browsing other tabs
- skip boring intros and pre-roll ads by fast forwarding
- save videos offline for private viewing
- control video playback with keyboard shortcuts on any site
- adjust brightness, saturation, and contrast of web videos
- extract and reduce latency on live streams

## When to choose
- you watch videos across many different websites and want consistent playback controls
- you need playback speed control beyond what a site natively offers
- you want keyboard-driven control including on cross-domain iframes and shadow DOM players
- you want a lightweight userscript instead of installing a full browser extension

## When to avoid
- you need DRM-protected streaming (Netflix, etc.) support, which userscripts cannot touch
- you want a standalone desktop video player rather than in-browser enhancement
- your browser does not support userscript managers like Tampermonkey
- you need advanced video editing or transcoding features
