Video Decoder: Common Types

Detailed Description

Defines and manages objects that decode video.

The NvMediaVideoDecoder object decodes compressed video data, writing the results to a NvMediaVideoSurface.

A specific NvMedia implementation may support decoding multiple types of compressed video data. However, NvMediaVideoDecoder objects are able to decode a specific type of compressed video data. This type must be specified during creation.

Typedef Documentation

NvMediaPictureInfo

typedef void NvMediaPictureInfo

A generic "picture information" pointer type.

This type serves solely to document the expected usage of a generic (void *) function parameter. In actual usage, the application is expected to physically provide a pointer to an instance of one of the "real" NvMediaPictureInfo* structures, picking the type appropriate for the decoder object in question.

Definition at line 94 of file nvmedia_common_decode.h.

NvMediaRefSurface

typedef void NvMediaRefSurface

A generic "reference surface" pointer type.

This type serves solely to document the expected usage of a generic (void *) function parameter. In actual usage, the application is expected to physically provide a pointer to an instance of NvMediaVideoSurface or NvMediaImage, depending on the type of decoder API used.

Enumeration Type Documentation

anonymous enum

anonymous enum

NAL types found in a bitstream packet.

This is used for TK1 H264 OTF cases.

Enumerator
NVMEDIA_SLH_PRESENT	slice header data present or not
NVMEDIA_SPS_PRESENT	sequence header data present or not
NVMEDIA_PPS_PRESENT	picture header data present or not

Definition at line 74 of file nvmedia_common_decode.h.

NvMediaDecoderInstanceId

enum NvMediaDecoderInstanceId

Specifies the decoder instance ID.

Enumerator
NVMEDIA_DECODER_INSTANCE_0	Specifies the decoder instance ID 0.
NVMEDIA_DECODER_INSTANCE_1	Specifies the decoder instance ID 1.
NVMEDIA_DECODER_INSTANCE_AUTO	Specifies that the decoder instance ID can be set dynamically during decode.
