v1.0.9-beta.2

[1.0.9-beta.2]

Added

• USB keyboard / wireless remote input handler — evdev-based listener
  with learn mode for custom key mapping; supports next, prev,
  pause, resume, toggle_pause, screen_on, and
  screen_off commands; mappings persisted in config.json under
  input.keyboard_map
• Keyboard/Remote Control card in Web UI Advanced page — per‑command
  learn and clear buttons with live key‑code display; learn mode polls
  for the next keypress and persists the mapping automatically
• toggle_pause IPC command — single‑key pause/resume toggle for
  keyboard remotes and the Web UI control endpoint; frontend shows a
  brief "Paused" / "Resumed" feedback popup on the frame display
• _show_feedback() helper in the frontend renderer — on‑screen
  popup messages for pause, resume, and toggle_pause actions using the
  existing message layer
• OTA system package support — new requirements-system.txt lists
  required system packages (python3-evdev); UpdateManager
  installs any missing packages before the pip step during OTA updates
• input config section — keyboard_enabled toggle and
  keyboard_map dictionary for storing learned key bindings

Changed

• Web UI polling — dashboard.js switched from setInterval to
  setTimeout chains for dashboard refresh, sync status, log viewer,
  and processing progress; prevents request‑queue buildup when the
  browser tab is backgrounded on mobile
• screen_on / screen_off renamed — display power commands
  renamed from legacy names across all input handlers (CEC, IR,
  keyboard, MQTT), IPC protocol, frontend renderer, and the Web UI
  control endpoint for consistent naming
• Pi 3 H.264 Level lowered — h264_level reduced from 4.2 to
  4.0 in the Pi 3 transcoding profile to stay within VideoCore IV
  hardware decode limits (max Level 4.1)
• Keyboard handler thread — started by the backend daemon alongside
  other input handlers; uses selectors‑based blocking I/O instead of
  busy‑polling so CPU usage is near‑zero when no keys are pressed

Fixed

• Pi 3 video stuttering / 100 % CPU — videos transcoded at H.264
  Level 4.2 exceeded VideoCore IV hardware decoder capabilities, causing
  VLC to fall back to software decode on all 4 cores; re‑transcoding at
  Level 4.0 enables hardware decode (~5–10 % CPU)
• Keyboard learn clear button — clearing a key mapping via the Web UI
  now properly removes the defaults for that command instead of wiping
  all default key bindings; set_key_map() merges config overrides
  with defaults, treating an empty list as "clear this command"
