Typedef Documentation

typedef struct ISPHDEC1_Obj* ISPHDEC1_Handle

Opaque handle to an ISPHDEC1 objects.

typedef IALG_Cmd ISPHDEC1_Cmd

Defines the control commands for the ISPHDEC1 module.

Remarks:

This ID can be extended in IMOD interface for additional control commands.

Enumeration Type Documentation

enum ISPHDEC1_FrameType

Decoder frame types.

Remarks:

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

See also:

ISPHDEC1_InArgs.frameType

Enumerator:

ISPHDEC1_FTYPE_SPEECHGOOD	Regular speech frame received without errors/loss.
ISPHDEC1_FTYPE_SIDUPDATE	SID update frames.
ISPHDEC1_FTYPE_NODATA	Untransmitted frame for codecs which support internal DTX.
ISPHDEC1_FTYPE_SPEECHLOST	Complete loss of speech frame.
ISPHDEC1_FTYPE_DEGRADED	Speech frame with a correct CRC, some invalid data.
ISPHDEC1_FTYPE_BAD	Speech frame (likely), but invalid.
ISPHDEC1_FTYPE_SIDFIRST	The first frame of comfort noise.
ISPHDEC1_FTYPE_SIDBAD	Corrupt SID update frame.
ISPHDEC1_FTYPE_ONSET	Frames which precede the first speech frame of a speech burst.
