FVP for DG-LAB – Funscript Video Player

Turn your videos into a physical experience. FVP is the most advanced funscript player for DG-LAB Coyote-3 on iPhone and iPad — precise, responsive, and built for real use.

REQUIREMENTS
• DG-LAB Coyote-3 (Bluetooth LE)
• iPhone or iPad with iOS 26 or later
• Video files with matching .funscript files

VIDEO & FILE MANAGEMENT
• Local folder browser — scans for .mp4, .mov and .m4v automatically
• WebDAV streaming — connect your home server and stream directly, no copying needed. Works with wsgidav, Synology, QNAP and more
• Funscript auto-matching by filename, or manual assignment via the "NF" button
• Favorites — heart-tap to mark, filter your list to favorites only
• Per-video A/B channel swap, stored individually per video
• JSON settings export & import with merge mode

SIGNAL & CHANNEL CONTROL
• Dual channel A/B — fully independent modes, frequency ranges, interpolation and curves per channel
• 3-Phase mode — three-electrode setup with configurable ground (A GND / B GND / common) and a ratio slider for full spatial depth
• 16 frequency modes: Fixed, Random, Speed, Speed-INV, Speed-UD, Speed-DU, POS, POS-INV, POS-UD, POS-DU, Speed+POS, Speed+POS-INV, Random-Mix, Random-Mix-Up
• Multichannel support — second funscript track auto-detected and routed to channel B

INTENSITY & FEEL
• Dynamic Intensity — automatically adjusts output for slow or large strokes. Three weighted factors (distance, duration, speed), curve equalizer, min/max output and predictive lookahead
• Wave / Classic Mix — blend a steady drone signal with the funscript-driven Classic signal, stepless from pure Classic to full Wave. Separate sliders for A and B in Dual mode
• Soft Limit A / B — hard output cap independent of the funscript, separate for A and B in Dual mode
• Auto intensity ramp — intensity rises automatically at random intervals (5–120 s)
• Min intensity floor A/B — constant baseline below the signal

SYNC & TIMING
• Auto delay — timecode pairing automatically calculates the BLE-to-video offset; tap when you feel the signal and the app computes the exact delay
• Startup delay — BLE starts on Play, video starts after a configurable countdown (0–5 s)
• GAP Fill — bridges script pauses with a gentle linear or random signal
• GAP Jump Auto — seeks to the next action point on long pauses

INTERPOLATION & CURVES
• 7 interpolation modes per channel: Linear, Sine, Full, 2x, Netto, Stroke, Manual
• Manual curve editor — 10 anchor points with Catmull-Rom spline, presets (Linear, S-Curve, Special-S), invert and live preview

SAFETY & RELIABILITY
• Emergency stop button — sets A and B to 0 instantly, always one tap away
• No-movement mute — cleanly mutes both channels when the funscript is silent
• Safety checklist on first launch
• BLE transport on a dedicated background queue — no stutter from UI interactions
• All settings saved via AppStorage with schema-versioned migrations

GENERAL
• Fully bilingual: German and English, switchable live without restart
