Detailed Description

Defines instance status parameters.

@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 @c size parameter.

Remarks:

The size field must be correctly set by the caller. See https://processors.wiki.ti.com/index.php/Extending_data_structures_in_XDM for more details.

Field Documentation

XDAS_Int32 IIMGDEC1_Status::size

Size of this structure in bytes. Because this structure can be extended, this field must be correctly set by the caller.

XDAS_Int32 IIMGDEC1_Status::extendedError

Extended error information.

Remarks:

When an internal error occurs, the algorithm will return an error return value (e.g. EFAIL, EUNSUPPORTED)

The value of each enum is the bit which is set.

Bits 31-16 are reserved. Bits 7-0 are codec and implementation specific.

The algorithm can set multiple bits to 1 based on conditions. e.g. it will set bits XDM_FATALERROR (fatal) and XDM_UNSUPPORTEDPARAM (unsupported params) in case of unsupported run time parameters.

This enumeration data type should not be used for storage, but rather only for its constant values.

XDM_ErrorBit

XDM1_SingleBufDesc IIMGDEC1_Status::data

Buffer descriptor for data passing.

                                @remarks   This buffer can be used as
                                           either input or output,
                                           depending on the command.

                                @remarks   The buffer will be provided
                                           by the application, and
                                           returned to the application
                                           upon return of the control()
                                           call.  The algorithm must
                                           not retain a pointer to this
                                           data.

                                @sa    #XDM_GETVERSION

XDAS_Int32 IIMGDEC1_Status::outputHeight

Output height.

XDAS_Int32 IIMGDEC1_Status::outputWidth

Output width. Padding should be taken care of by the decoder.

XDAS_Int32 IIMGDEC1_Status::imageWidth

Image width.

XDAS_Int32 IIMGDEC1_Status::outputChromaFormat

Chroma formats.

@remarks This enumeration data type should not be used for storage, but rather only for its constant values.

@remarks This enumeration defines a base set of values.  Algorithms which require proprietary enumeration values may define them - much like extended fields in base structures.  These extended enums should be between #XDM_CUSTOMENUMBASE and 0x7FFF.

                                 @sa XDM_ChromaFormat

XDAS_Int32 IIMGDEC1_Status::totalAU

Total number of Access Units.

XDAS_Int32 IIMGDEC1_Status::totalScan

Total number of scans.

XDM_AlgBufInfo IIMGDEC1_Status::bufInfo

Input and output buffer information.
