Detailed Description

This structure defines the algorithm 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.

@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 IIMGENC_DynamicParams::size

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

XDAS_Int32 IIMGENC_DynamicParams::numAU

Number of Access unit to encode. Set to XDM_DEFAULT to encode the entire frame.

XDAS_Int32 IIMGENC_DynamicParams::inputChromaFormat

Input chroma format.

                                 @sa   XDM_ChromaFormat

XDAS_Int32 IIMGENC_DynamicParams::inputHeight

Input frame height.

XDAS_Int32 IIMGENC_DynamicParams::inputWidth

Input frame width.

XDAS_Int32 IIMGENC_DynamicParams::captureWidth

Pitch. If set to zero, imageWidth is used; else, this field (assuming it's larger than imageWidth) is used.

XDAS_Int32 IIMGENC_DynamicParams::generateHeader

Header generation mode.

                                @sa    XDM_EncMode

XDAS_Int32 IIMGENC_DynamicParams::qValue

Quality factor for encoder. Set to a value between 0 (lowest quality) and 100 (highest quality).
