Constructor & Destructor Documentation

◆ HEVCHRDParameters()

ts::HEVCHRDParameters::HEVCHRDParameters	(	const uint8_t *	data = `nullptr`,
		size_t	size = `0`,
		bool	commonInfPresentFlag = `false`,
		size_t	maxNumSubLayersMinus1 = `0`
	)

Constructor from a binary area.

Note: the two parameters commonInfPresentFlag 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]	commonInfPresentFlag	HRD common info present (depends on parent structure).
[in]	maxNumSubLayersMinus1	Number of sub-layers minus 1 (depends on parent structure).

Member Function Documentation

◆ clear()

virtual void ts::HEVCHRDParameters::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::HEVCHRDParameters::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::HEVCHRDParameters::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::HEVCHRDParameters::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 , typename std::enable_if< std::is_integral< INT >::value >::type * = nullptr>

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 , typename std::enable_if< std::is_integral< INT >::value >::type * = nullptr>

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.
