Summary

Adds higher playback speeds and configurable long-press speed.

• The speed dialog now goes up to 4x (was 2x), with presets 0.25x–2x plus 3x and 4x.
• New "LongPress speed" setting: 1.5x–5x, default 2x.
• Holding while already at or above that speed doubles it (eg 2x → 4x, capped at 8x) and the indicator shows the current speed. Releasing restores exact speed from before the hold.

Long-press was fixed at 2x, so it did nothing for anyone already watching at 2x.

Changes

• PlaybackSpeeds.kt: New, Limits and escalation logic shared by the dialog and gesture helper.
• PlayerGestureHelper.kt, FullScreenPlayer.kt: for the hold gesture and dialog bounds.
• SettingsPlayerScreen.kt, DevicePreferenceStore.kt, settings_player.xml, array.xml, strings: new speedup_speed_key pref (percent, 200 = 2x).
• speed_dialog.xml: two rows of presets, D-pad focus chain updated. The speed-up indicator in the phone, TV and trailer layouts is now wrap_content so the text fits.

The speed button and long-press speed-up now default to on (previously off). Explicit user choices are unaffected. Happy to revert this if you'd rather keep the old defaults.

Testing

• Built assemblePrereleaseDebug and tested on multiple Android phones.
• ./gradlew lint check passes.

Note: This implementation was written with AI assistance (Claude). I tested the change on a device and can explain and fix all of it if needed.
