Member Typedef Documentation

◆ SuperClass

using ts::HEVCVUIParameters::SuperClass = AbstractVideoStructure

Reference to the superclass.

Constructor & Destructor Documentation

◆ HEVCVUIParameters()

ts::HEVCVUIParameters::HEVCVUIParameters	(	const uint8_t *	data = nullptr,
		size_t	size = 0,
		size_t	sps_max_sub_layers_minus1 = 0 )

Constructor from a binary area. Note: the parameter sps_max_sub_layers_minus1 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]	sps_max_sub_layers_minus1	Number of sub-layers minus 1 (depends on parent structure).

Member Function Documentation

◆ clear()

virtual void ts::HEVCVUIParameters::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::HEVCVUIParameters::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::HEVCVUIParameters::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::HEVCVUIParameters::display	(	std::ostream &	stream,
		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.
