Typedef Documentation

typedef struct ISPHDEC_Obj ISPHDEC_Obj

This must be the first field of all ISPHDEC instance objects.

typedef struct ISPHDEC_Obj* ISPHDEC_Handle

Opaque handle to an ISPHDEC objects.

typedef struct ISPHDEC_Params ISPHDEC_Params

Defines the creation time parameters for all ISPHDEC instance objects.

Remarks:

The application should set the parameters to 0 to use the algorithm's default values.

This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the size parameter.

The size field must be correctly set by the caller. See http://tiexpressdsp.com/index.php?title=Extending_data_structures_in_xDM for more details.

typedef struct ISPHDEC_DynamicParams ISPHDEC_DynamicParams

This structure defines the codec parameters that can be modified after creation via control() calls.

Remarks:

It is not necessary that given implementation support all dynamic parameters to be configurable at run time. If a particular algorithm does not support run-time updates to a parameter that the application is attempting to change at runtime, it may indicate this as an error.

This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the size parameter.

The size field must be correctly set by the caller. See http://tiexpressdsp.com/index.php?title=Extending_data_structures_in_xDM for more details.

ISPHDEC_Fxns::control()

typedef struct ISPHDEC_InArgs ISPHDEC_InArgs

Defines the input arguments for all ISPHDEC instance process function.

Remarks:

This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the size parameter.

The size field must be correctly set by the caller. See http://tiexpressdsp.com/index.php?title=Extending_data_structures_in_xDM for more details.

ISPHDEC_Fxns::process()

typedef struct ISPHDEC_Status ISPHDEC_Status

Defines instance status parameters (read-only).

Remarks:

Remarks:

This ID can be extended in IMOD interface for additional controls.
