关于此扩展
VelociPlay gives you fast, precise control over the playback speed of any HTML5 <video> or <audio> element, on any website — without digging through each player's menus.
Features
Works everywhere HTML5 media plays: YouTube, streaming sites, course platforms, podcasts, and local files.
Controls both video and audio elements.
Fine-grained speed from 0.07x to 16x in configurable steps.
A draggable on-media controller showing the current speed, which you can reposition anywhere.
Per-site speed rules — set a default speed for specific domains (e.g. always 2x on lecture sites).
Per-site disable — turn the controller off on sites where you don't want it.
Optional "remember speed" that persists your last speed across tabs and sessions.
Speed fightback — reapplies your chosen speed when a player tries to reset it.
Fully customizable keyboard shortcuts, including modifier combos and multiple preferred-speed toggles.
Custom controller CSS for advanced positioning and styling.
Import and export all your settings as a single file.
Default keyboard shortcuts
S slower · D faster · R reset to 1x · Z rewind · X advance · A preferred speed · V show/hide controller · P set marker · O jump to marker. All shortcuts are fully customizable in Settings.
Privacy
