Detailed Description

HEVC profile, tier and level structure.

ITU-T Rec. H.265, 7.3.3

Constructor & Destructor Documentation

HEVCProfileTierLevel()

ts::HEVCProfileTierLevel::HEVCProfileTierLevel	(	const uint8_t *	data = nullptr,
		size_t	size = 0,
		bool	profilePresentFlag = false,
		size_t	maxNumSubLayersMinus1 = 0
	)

Constructor from a binary area.

Note: the two parameters profilePresentFlag and maxNumSubLayersMinus1 must be passed in the initializer list of the parse() methods.

Parameters

[in]	data	Address of binary data to analyze.
[in]	size	Size in bytes of binary data to analyze.
[in]	profilePresentFlag	HRD profile info is present (depends on parent structure).
[in]	maxNumSubLayersMinus1	Number of sub-layers minus 1 (depends on parent structure).

Member Function Documentation

profile()

uint8_t ts::HEVCProfileTierLevel::profile

(

)

const

Get the profile value.

Returns

The profile value.

clear()

virtual void ts::HEVCProfileTierLevel::clear ( )

overridevirtual

Clear all values.

Should be reimplemented by subclasses. The data are marked invalid.

Reimplemented from ts::AbstractVideoData.

parse() [1/2]

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

overridevirtual

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.

Reimplemented from ts::AbstractVideoStructure.

parse() [2/2]

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

overridevirtual

Parse the structure.

Must be reimplemented by subclasses. The data are marked as valid or invalid.

Parameters

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

Returns

The valid flag.

Implements ts::AbstractVideoStructure.

display()

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

overridevirtual

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.

Implements ts::DisplayInterface.

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.
