Video Speed Controller (YouTube + RuTube)

Adds speed buttons, slider, and hotkeys to YouTube and RuTube videos. Bilingual interface (English/Russian).

Video Speed Controller adds an always-visible row of speed buttons, a fine-grained slider, and customizable keyboard shortcuts to videos on YouTube and RuTube. WHAT IT DOES - 9 preset speed buttons on YouTube (1x, 1.25x, 1.5x, 1.75x, 2x, 2.5x, 3x, 3.5x, 4x) and 7 on RuTube (1x through 3x), positioned right below the video. - Slider for in-between values, with a coloured fill that tracks the current speed. - Single-click on a button = temporary speed for this video only. Double-click = save as the default for that site. - Configurable hotkeys (default Ctrl+C +0.1 / Ctrl+V -0.1) — assign multiple combinations per action so a remote and a keyboard can both trigger speed changes. - In-player gear menu with three tabs: - General: slider position (right / below / inside player), language switch (English / Russian), behavior toggles, advanced auto-recover and self-diagnostics switches. - Shortcuts: rebind speed-up / speed-down, add additional combos, reset to defaults. - Diagnostics: copy a structured report for bug submissions; clear cached selectors if a site update breaks the panel. - Toolbar popup mirrors the in-player menu so you can adjust settings without opening a video. - RuTube-only quality-of-life toggles: hide the overlay player title, hide Premium subscription banners. WHY IT'S RELIABLE When YouTube or RuTube ships a layout change, the panel recovers automatically through a five-strategy discovery chain (cached selector → exact match → substring match → walk up from the video element → geometric heuristic). A built-in watchdog detects broken state, purges bad cache entries, and re-attaches the panel. If the player SPA-navigates between videos, the panel re-mounts via a MutationObserver without losing your settings.
