Introduction

This is VISS H3A Configuration file

Files
file	h3a_cfg.h
	Interface file for H3A module, Defines the structures / control operations that could be used to configure / control H3A module in VISS H3A is independent module, which takes input from RAWFE. This is why a separate interface file is used for controlling H3A.

struct	H3a_Config
	Structure for H3A configuration VPAC can output only one of AF or AEWB output. This structure is used for selecting H3A output module AF/AEWB and also used for for setting module configuration. When AF is enabled as an output module, only AF will be configured. Also when AEWB module is enabled/selected as an output module, only AEWB mdule will be configured. More...

H3A IOCTL macros
Control commands for H3A module in VISS Mainly used to set H3A AF/AEWB configuration
#define	IOCTL_H3A_SET_CONFIG (VHWA_IOCTL_H3A_IOCTL_BASE)
	Ioctl for setting H3A parameters. Only one of AF or AEWB module can be configured at a time. Only one of AF and AEWB can be enabled in the H3A module at a time for a frame. So this ioctl enables/supports only one of these modules. Refer to structure H3a_Config. More...

#define	IOCTL_H3A_GET_AEWB_SIZE (IOCTL_H3A_SET_CONFIG + 1U)
	Ioctl for Getting H3a output size for AF/AEWB module. Depending on the H3A AF/AEWB module enabled, it returns the output frame size. Refer to structure H3a_Config. More...

Macro Definition Documentation

◆ IOCTL_H3A_SET_CONFIG

#define IOCTL_H3A_SET_CONFIG (VHWA_IOCTL_H3A_IOCTL_BASE)

Ioctl for setting H3A parameters. Only one of AF or AEWB module can be configured at a time. Only one of AF and AEWB can be enabled in the H3A module at a time for a frame. So this ioctl enables/supports only one of these modules. Refer to structure H3a_Config.

Returns: FVID2_SOK on success, else error code.

◆ IOCTL_H3A_GET_AEWB_SIZE

#define IOCTL_H3A_GET_AEWB_SIZE (IOCTL_H3A_SET_CONFIG + 1U)

Ioctl for Getting H3a output size for AF/AEWB module. Depending on the H3A AF/AEWB module enabled, it returns the output frame size. Refer to structure H3a_Config.

Returns: FVID2_SOK on success, else error code.
