SuperClass

using ts::AbstractHEVCAccessUnit::SuperClass = AbstractVideoAccessUnit

Unified name for superclass.

ts::AbstractHEVCAccessUnit::AbstractHEVCAccessUnit ( )

default

Constructor.

Member Function Documentation

clear()

virtual void ts::AbstractHEVCAccessUnit::clear ( )

overridevirtual

Clear all values. Should be reimplemented by subclasses. The data are marked invalid.

Reimplemented from ts::AbstractVideoAccessUnit.

Reimplemented in ts::HEVCAccessUnitDelimiter, and ts::HEVCSequenceParameterSet.

parseHeader()

virtual bool ts::AbstractHEVCAccessUnit::parseHeader ( const uint8_t *& addr, size_t & size, std::initializer_list< uint32_t > params = std::initializer_list< uint32_t >() )

overrideprotectedvirtual

Parse the header of the access unit. Must be reimplemented by subclasses. The data are marked as valid or invalid.

Parameters

[in,out]	addr	Address of the binary data to parse. Adjusted after header.
[in,out]	size	Size in bytes of the binary data to parse. Adjusted as remaining size after header.
[in]	params	Additional parameters. May be needed by some structures.

Returns

The valid flag.

Implements ts::AbstractVideoAccessUnit.

parse()

virtual bool ts::AbstractVideoAccessUnit::parse ( const uint8_t * addr, size_t size, std::initializer_list< uint32_t > params = std::initializer_list< uint32_t >() )

overridevirtualinherited

Parse a memory area containing binary video data of the expected type. Must be reimplemented by subclasses. The data are marked as valid or invalid.

Parameters

[in]	addr	Address of the binary data to parse.
[in]	size	Size in bytes of the binary data to parse.
[in]	params	Additional parameters. May be needed by some structures.

Returns

The valid flag.

Implements ts::AbstractVideoData.

parseBody()

virtual bool ts::AbstractVideoAccessUnit::parseBody ( AVCParser & parser, std::initializer_list< uint32_t > params = std::initializer_list< uint32_t >() )

protectedpure virtualinherited

Parse the body of the access unit up to but not including the rbsp_trailing_bits. Must be reimplemented by subclasses. The data are marked as valid or invalid.

Parameters

[in,out]	parser	The parser of an AVC-like video stream.
[in]	params	Additional parameters. May be needed by some structures.

Returns

The valid flag.

Implemented in ts::AVCAccessUnitDelimiter, ts::AVCSequenceParameterSet, ts::HEVCAccessUnitDelimiter, ts::HEVCSequenceParameterSet, and ts::VVCAccessUnitDelimiter.

disp() [1/2]

template<typename INT>
requires std::integral<INT>

void ts::AbstractVideoData::disp ( std::ostream & out, const UString & margin, const UChar * name, INT n ) const

inlineprotectedinherited

Display helper for subclasses. Display an integer value.

Template Parameters

INT	An integer type.

Parameters

[in,out]	out	The stream where to print the content.
[in]	margin	The prefix string on each line.
[in]	name	A name to display for the value.
[in]	n	The integer value to display.

disp() [2/2]

template<typename INT>
requires std::integral<INT>

void ts::AbstractVideoData::disp ( std::ostream & out, const UString & margin, const UChar * name, std::vector< INT > n ) const

inlineprotectedinherited

Display helper for subclasses. Display a vector of integer value.

Template Parameters

INT	An integer type.

Parameters

[in,out]	out	The stream where to print the content.
[in]	margin	The prefix string on each line.
[in]	name	A name to display for the value.
[in]	n	The integer values to display.

display()

virtual std::ostream & ts::DisplayInterface::display ( std::ostream & stream = std::cout, const UString & margin = UString(), int level = Severity::Info ) const

pure virtualinherited

Display the content of this object to a stream.

Parameters

[in,out]	stream	The stream where to print the content. Standard output by default.
[in]	margin	The prefix string on each line, empty by default.
[in]	level	Severity level (for instance, Severity::Info or Severity::Debug may display more information).

Returns

A reference to stream.

Implemented in ts::AVCAccessUnitDelimiter, ts::AVCHRDParameters, ts::AVCSequenceParameterSet, ts::AVCVUIParameters, ts::HEVCAccessUnitDelimiter, ts::HEVCHRDParameters, ts::HEVCProfileTierLevel, ts::HEVCScalingListData, ts::HEVCSequenceParameterSet, ts::HEVCShortTermReferencePictureSetList, ts::HEVCVUIParameters, ts::ModulationArgs, ts::SignalState, and ts::VVCAccessUnitDelimiter.
