Detailed Description

Video attributes for Advanced Video Coding.

AVC is Advanced Video Coding, ISO 14496-10, ITU H.264.

An AVCAttributes object is built by transmitting AVC access units (aka "NALunits"). The state of the object may change after adding a "sequence parameter set" NALunit. Initially, an AVCAttributes object is invalid.

Member Function Documentation

moreBinaryData()

virtual bool ts::AVCAttributes::moreBinaryData ( const uint8_t *  addr, size_t  size  )

overridevirtual

Provides an audio/video binary data to be analyzed by this instance.

The type of data (complete PES payload or some type of "frame" or "access unit") depends on the type of audio/video.

Parameters

[in]	addr	Address of data to be analyzed.
[in]	size	Size of data to be analyzed.

Returns

True if the attributes object becomes valid or has new values.

Implements ts::AbstractAudioVideoAttributes.

toString()

virtual UString ts::AVCAttributes::toString ( ) const

overridevirtual

Convert to a string object.

Returns

This object, converted as a string.

Implements ts::StringifyInterface.

horizontalSize()

size_t ts::AVCAttributes::horizontalSize ( ) const

inline

Get video horizontal size in pixels.

Returns

Video horizontal size in pixels.

verticalSize()

size_t ts::AVCAttributes::verticalSize ( ) const

inline

Get video vertical size in pixels.

Returns

Video vertical size in pixels.

profile()

int ts::AVCAttributes::profile ( ) const

inline

Get AVC profile.

Returns

AVC profile, 0 if unknown.

profileName()

UString ts::AVCAttributes::profileName

(

)

const

Get AVC profile name.

Returns

AVC profile as a string.

level()

int ts::AVCAttributes::level ( ) const

inline

Get AVC level.

Returns

AVC level, 0 if unknown.

levelName()

UString ts::AVCAttributes::levelName

(

)

const

Get AVC level name.

Returns

AVC level as a string.

chromaFormat()

uint8_t ts::AVCAttributes::chromaFormat ( ) const

inline

Get chroma format.

Returns

Chroma format, code values are CHROMA_* from tsMPEG.h, 0 if unknown.

chromaFormatName()

UString ts::AVCAttributes::chromaFormatName

(

)

const

Get chroma format name.

Returns

Chroma format as a string.

isValid()

bool ts::AbstractAudioVideoAttributes::isValid ( ) const

inlineinherited

Check if the values in the object are valid.

Returns

True if the values in the object are valid.

invalidate()

void ts::AbstractAudioVideoAttributes::invalidate ( )

inlineinherited

Invalidate the content of this instance.

It must be rebuilt using audio/video binary data.

Member Data Documentation

_is_valid

bool ts::AbstractAudioVideoAttributes::_is_valid = false

protectedinherited

A flag which indicates if the content of this object is valid.

It is the responsibility of the subclasses to set it.
