SWF GUI Mock Server (see running guide)

Parts None required

Overview

The RED ONE MX on-camera display is driven by a Flash SWF (ActionScript 2) that runs inside the VxWorks RTOS. It communicates with the firmware over a raw XMLSocket on TCP port 49152. All menus, parameter controls, button handling, and monitoring overlays are implemented in this SWF.

This reference was derived by:

Decompiling firmware/reverse/build_32/assets/swf_gui_1.swf with JPEXS
Parsing firmware/tools/factory_defaults.xml (893 camera parameters)
Analysing firmware/reverse/build_32/assets/panels.xml (full menu definition)
Reading the decompiled ActionScript managers in firmware/reverse/build_32/assets/swf_gui_1_as/

Notation: Parameter names in parentheses (e.g. GUI.PAINT.EXPOSURE.ISO) are the internal GPDB (Global Parameter Data Block) identifiers sent over the XMLSocket protocol. They can be used directly with the mock server or the camera's TCP interface.

Boot Sequence

When the SWF connects to the camera, it goes through a fixed handshake before the GUI becomes interactive:

Stage	Event	Description
1	TCP connect	SWF connects to port 49152
2	AUTH_SEED	Server sends a random OTP seed
3	AUTH_PASS	SWF sends OTP-encrypted MD5 password hash
4	GET_FILE	Server delivers `factory_defaults.xml` — all 893 param definitions
5	GET_PARAM *	Server delivers current values for all params
6	SYNC_EVENT_0/1/2	Three synchronisation events trigger `GoSplash()` then `GoCamera()`
7	panels.xml	SWF fetches the menu definition via HTTP
8	GUI_STATE_5_READY	Full interactive state; all menus and button injection active

The authentication supports two roles: admin (password hash 1b772ea5a3dc1e140c4240b335b1d8b8) and a lower-privilege user role.

Hardware Button Mapping

The camera body exposes dedicated buttons that the firmware reports to the SWF as GPDB boolean events. Each button fires its parameter to "true" on press.

Fixed-function Buttons

Button	Parameter	Action
RECORD	`GUI.RAWINPUT.BUTTON.RECORD`	Start/stop recording (or burst in BURST mode)
SENSOR	`GUI.RAWINPUT.BUTTON.MENU.SENSOR`	Open SENSOR menu
VIDEO	`GUI.RAWINPUT.BUTTON.MENU.VIDEO`	Open AV (audio/video) menu
SYSTEM	`GUI.RAWINPUT.BUTTON.MENU.SYSTEM`	Open SYSTEM menu (disabled while recording)
SYSTEM (hold)	`GUI.RAWINPUT.BUTTON.MENU.SYSTEM_LONG`	Long-press system (unimplemented in Build 32)
Supergrip REC	`SYSTEM.DEV.SUPERGRIP.RAWINPUT.BUTTON.REC`	Same as RECORD button

User buttons A, B, and C jump to a stored menu panel on press and assign the current panel on hold (via SET_A/B/C):

Button	Parameter (press)	Parameter (hold/set)	Stored in
USER A	`GUI.RAWINPUT.BUTTON.USER_DEFINED.A`	`GUI.RAWINPUT.BUTTON.USER_DEFINED.SET_A`	`GUI.KEYMAP.USER_A.MENU`
USER B	`GUI.RAWINPUT.BUTTON.USER_DEFINED.B`	`GUI.RAWINPUT.BUTTON.USER_DEFINED.SET_B`	`GUI.KEYMAP.USER_B.MENU`
USER C	`GUI.RAWINPUT.BUTTON.USER_DEFINED.C`	`GUI.RAWINPUT.BUTTON.USER_DEFINED.SET_C`	`GUI.KEYMAP.USER_C.MENU`

These buttons execute a configurable KEYFNC_* function. Each has an enable checkbox and a function selector in SETUP > PREFERENCES > KEYMAP > USER KEYS.

Button label	Parameter	Keymap param
USER-1 / Side D	`GUI.RAWINPUT.BUTTON.SIDE.USER_DEFINED.D`	`GUI.KEYMAP.USER_D.*`
USER-2 / Side E	`GUI.RAWINPUT.BUTTON.SIDE.USER_DEFINED.E`	`GUI.KEYMAP.USER_E.*`

USER-4 / EVF C	`SYSTEM.DEV.EVF.RAWINPUT.BUTTON.C`	`GUI.KEYMAP.EVF_C.*`
USER-5 / LCD SW1	`SYSTEM.DEV.LCD.RAWINPUT.BUTTON.SW1`	`GUI.KEYMAP.LCD_A.*`
Side Record	`GUI.RAWINPUT.BUTTON.SIDE.RECORD`	`GUI.KEYMAP.SIDE_RECORD.*`

Recording Modes

The camera supports three recording modes set via VIDEO.RECORD.MODE:

Mode	Description
`CONTINUOUS`	Normal start/stop recording
`TIMELAPSE`	Timelapse with configurable interval and burst size
`BURST`	Burst capture triggered by record button or `KEYFNC_DO_BURST`

Pre-record (enabled via GUI.RECORD.PRERECORD.ENABLED) maintains a rolling buffer so the camera effectively records a few seconds before the record button is pressed.
