IVIDENC_Params Struct Reference
[XDM IVIDENC Video Encoder Interface]

#include <ividenc.h>

Detailed Description

Defines the creation time parameters for all IVIDENC instance objects.

Remarks:
The application should set the parameters to 0 to use the algorithm's default values.

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.

Field Documentation

XDAS_Int32 IVIDENC_Params::size

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

XDAS_Int32 IVIDENC_Params::encodingPreset

Encoding preset.

XDAS_Int32 IVIDENC_Params::rateControlPreset

Video rate control presets.

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

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.

XDAS_Int32 IVIDENC_Params::maxHeight

Maximum height.

XDAS_Int32 IVIDENC_Params::maxWidth

Maximum width.

XDAS_Int32 IVIDENC_Params::maxFrameRate

Maximum frame rate * 1000.

XDAS_Int32 IVIDENC_Params::maxBitRate

Maximum bit rate, bits per second.

XDAS_Int32 IVIDENC_Params::dataEndianness

Endianness of output data.

XDAS_Int32 IVIDENC_Params::maxInterFrameInterval

I to P frame distance. e.g. = 1 if no B frames, 2 to insert one B frame.

XDAS_Int32 IVIDENC_Params::inputChromaFormat

Chroma format for the input buffer.

See also:
XDM_ChromaFormat

XDAS_Int32 IVIDENC_Params::inputContentType

Video content type of the buffer being encoded.
