Detailed Description

Defines the creation time parameters for all ISPHENC1 instance objects.

Remarks:
Some of the fields in this structure are optional and depend on the class of speech encoder you're creating.
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 https://processors.wiki.ti.com/index.php/Extending_data_structures_in_XDM for more details.

Field Documentation

XDAS_Int16 ISPHENC1_Params::size

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

XDAS_Int16 ISPHENC1_Params::frameSize

Input frame size in bytes for sample based codecs.

XDAS_Int16 ISPHENC1_Params::compandingLaw

Optional, codec-specific companding law. See your codec-specific interface documentation options.

ISPEECH1_PCM_CompandingLaw
ISPEECH1_G726_CompandingLaw
XDAS_Int16 ISPHENC1_Params::packingType

Optional, codec-specific packing type. See your codec-specific interface documentation options.

See also:
ISPEECH1_AMR_PackingType
ISPEECH1_G726_PackingType
ISPEECH1_WBAMR_PackingType
XDAS_Int16 ISPHENC1_Params::vadSelection

Optional, codec-specific voice activity detection selection. See your codec-specific interface documentation options.

See also:
ISPEECH1_AMR_VADSelect
ISPEECH1_SMV_VADSelect
XDAS_Int16 ISPHENC1_Params::codecSelection

Optional, codec-specific codec selection. See your codec-specific interface documentation options.

See also:
ISPEECH1_AMR_CodecSelect
ISPHENC1_Params.codecSelection
XDAS_Int16 ISPHENC1_Params::bitRate

Optional, codec-specific bit rate. See your codec-specific interface documentation options.

See also:
ISPEECH1_AMR_BitRate
ISPEECH1_G723_BitRate
ISPEECH1_G726_BitRate
ISPEECH1_WBAMR_BitRate
XDAS_Int16 ISPHENC1_Params::reserved

Reserved - serves to pad this structure.

XDAS_Int8** ISPHENC1_Params::tablesPtr

Optional pointer to the codec's initialization tables.

Remarks:
This parameter specifies a pointer to the array of the codec's table block pointers. If the application requires the codec to select the default table address array pointer, it should set this to NULL.
