Player for video szerző: kvachikk

Firefox for Android's built-in video controls are a thin progress line and a play
button. Nocturne Player replaces them with controls built for a thumb.

Controls

• Seek bar — thick and raised off the bottom edge. Grab it anywhere, not just
  at the current position, and it moves with your finger. Slide your finger away from
  the bar and scrubbing gets finer, so you can land on an exact moment in a long film.
  The time you started from stays on the left, so you can always get back.
• Tap anywhere to pause. The picture fades to grey while paused, like Netflix.
• −10 and +10 buttons either side of play, and a double-tap on either side of
  the screen does the same.
• Hold either side to scrub at 2x, forward or back.
• Pinch — the picture fills the screen from the start, with no black bars;
  pinch to go back to the full frame and it snaps cleanly between the two.

Picture

• Night light — warms the picture to a comfortable amber for watching in the dark.
• Brightness, contrast and saturation — adjusted with + and − buttons, not fiddly
  sliders. With everything at its default the picture is passed through untouched.

Subtitles

• Use the site's own tracks, or load an .srt / .vtt file from your phone.
• Adjustable size, and a sync offset for when subtitles drift.

Also

• Playback speed from 0.5x to 2x.
• Quality switching where a site offers several sources.
• Settings are remembered on your device.

Privacy

Nocturne Player has no network access at all. There is no fetch, no XMLHttpRequest,
no beacon and no remote URL anywhere in the source — a continuous integration check
fails the build if any of them ever appear. It asks for two permissions: storage, to
remember your settings on your device, and activeTab, so the popup can show which
site you are on. Nothing is collected and nothing is sent anywhere.

Scope

Built for ordinary sites that play video through a plain HTML video element. It
deliberately does not touch YouTube, Vimeo or TikTok — those ship their own player
layers.

Known limits

• Picture-in-Picture does not work on Android — Firefox has no PiP API there yet.
• Video quality usually cannot be changed: sites streaming HLS or DASH pick it in
  their own code.
• Volume is left to the phone's own buttons.
• There is no sound while holding to scrub.
