XDAIS: XDM IVIDDEC2 Video Decoder Interface

#define IVIDDEC2_MAX_IO_BUFFERS 20

Maximum I/O Buffers.

See also:: IVIDDEC2_OutArgs

#define IVIDDEC2_EOK XDM_EOK

Success.

#define IVIDDEC2_EFAIL XDM_EFAIL

General failure.

#define IVIDDEC2_EUNSUPPORTED XDM_EUNSUPPORTED

Request is unsupported.

typedef struct IVIDDEC2_Obj* IVIDDEC2_Handle

Opaque handle to an IVIDDEC2 objects.

typedef IALG_Cmd IVIDDEC2_Cmd

Defines the control commands for the IVIDDEC2 module.

Remarks:: This ID can be extended in IMOD interface for additional controls.

See also:: XDM_CmdId
IVIDDEC2_Fxns::control()

enum IVIDDEC2_FrameOrder

Video decoder output frame order.

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

See also:: IVIDDEC2_DynamicParams::frameOrder

Enumerator:

IVIDDEC2_DISPLAY_ORDER

The decoder provides decoded output in in the actual order of displaying the output buffer. The codec assumes the responsibility of reordering the frames.

Remarks:

The output buffer will be delayed by one frame, regardless of whether the frame contains I/P or I/P/B frames.

This is the default mode.

This mode is required to be supported by all video decoder codecs.

IVIDDEC2_DECODE_ORDER

The decoder provides decoded output in the the order of decoding. There will be no delay in the output buffers.

Remarks:: It is the application's responsibility to handle the frame re-ordering.
This mode is optional. If it is not supported by the decoder, IVIDDEC_EUNSUPPORTED will be returned.

IVIDDEC2_FRAMEORDER_DEFAULT

Default setting.
