Detailed Description

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.

Field Documentation

XDAS_Int32 IVIDDEC_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 IVIDDEC_DynamicParams::decodeHeader

Number of access units to decode.

XDM_DecMode

XDAS_Int32 IVIDDEC_DynamicParams::displayWidth

Pitch. If set to zero, use the decoded image width. Else, use given display width in pixels.

XDAS_Int32 IVIDDEC_DynamicParams::frameSkipMode

Frame skip mode.
