Constructor & Destructor Documentation

◆ HEVCSequenceParameterSet()

ts::HEVCSequenceParameterSet::HEVCSequenceParameterSet	(	const uint8_t *	data = `nullptr`,
		size_t	size = `0`
	)

Constructor from a binary area.

Parameters

[in]	data	Address of binary data to analyze.
[in]	size	Size in bytes of binary data to analyze.

Member Function Documentation

◆ clear()

virtual void ts::HEVCSequenceParameterSet::clear ( )

overridevirtual

Clear all values.

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

Reimplemented from ts::AbstractHEVCAccessUnit.

◆ display()

virtual std::ostream & ts::HEVCSequenceParameterSet::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.

◆ chroma()

uint8_t ts::HEVCSequenceParameterSet::chroma ( ) const

Get chroma_format_idc, applying default value (see H.264 7.4.2.1.1).

Returns: The chroma_format_idc, applying default value.

◆ frameWidth()

uint32_t ts::HEVCSequenceParameterSet::frameWidth ( ) const

Frame width in pixels.

Returns: The frame width in pixels.

◆ frameHeight()

uint32_t ts::HEVCSequenceParameterSet::frameHeight ( ) const

Frame height in pixels.

Returns: The frame height in pixels.

overrideprotectedvirtualinherited

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.

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.
