Typedef Documentation

typedef struct IVIDTRANSCODE_Obj IVIDTRANSCODE_Obj

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

typedef struct IVIDTRANSCODE_Obj* IVIDTRANSCODE_Handle

Opaque handle to an IVIDTRANSCODE objects.

typedef struct IVIDTRANSCODE_Params IVIDTRANSCODE_Params

Defines the creation time parameters for all IVIDTRANSCODE instance objects.

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.

typedef struct IVIDTRANSCODE_DynamicParams IVIDTRANSCODE_DynamicParams

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

Remarks:

It is not necessary that a 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.

IVIDTRANSCODE_Fxns::control()

typedef struct IVIDTRANSCODE_InArgs IVIDTRANSCODE_InArgs

Defines the input arguments for all IVIDTRANSCODE 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.
