Control OBS Studio scenes and encoding

Debug OBS WebSocket integration for X-Touch control

Debugging real-time bidirectional OBS control via physical X-Touch controller with multi-camera scene switching and transform caching.

• · OBS WebSocket host/port/password config
• · action name and parameters
• · scene/source/transform specifications

• · OBS scene/source state changes
• · error messages with connection status

• · obws crate
• · OBS WebSocket API 4455

• · OBS Studio running on configured host:port
• · XTouch-GW src/drivers/obs/ modules present
• · Rust 1.56+ with async-trait

• · Connection refused if OBS not running or wrong port
• · Scene not found if name mismatch or case-sensitive error
• · Transform cache stale if scene change not invalidated
• · Auth failure if OBS password incorrect

• · Documented async reconnection logic with exponential backoff
• · Transform cache invalidation on scene change
• · Encoder acceleration curves for tactile fader response
• · Multi-camera split control (PiP mode)
• · Driver trait pattern with interior mutability (Arc<RwLock<>>)
