Typedef Documentation

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.

Enumeration Type Documentation

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.
