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.

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.

Field Documentation

XDAS_Int32 IIMGENC1_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 IIMGENC1_DynamicParams::numAU

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

XDAS_Int32 IIMGENC1_DynamicParams::inputChromaFormat

Input chroma format.

See also:

XDM_ChromaFormat

XDAS_Int32 IIMGENC1_DynamicParams::inputHeight

Input frame height.

XDAS_Int32 IIMGENC1_DynamicParams::inputWidth

Input frame width.

XDAS_Int32 IIMGENC1_DynamicParams::captureWidth

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

XDAS_Int32 IIMGENC1_DynamicParams::generateHeader

Header generation mode.

See also:

XDM_EncMode

XDAS_Int32 IIMGENC1_DynamicParams::qValue

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