Constructor & Destructor Documentation

◆ HEVCSequenceParameterSet()

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

Constructor from a binary area.

Parameters
[in]dataAddress of binary data to analyze.
[in]sizeSize 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]streamThe stream where to print the content. Standard output by default.
[in]marginThe prefix string on each line, empty by default.
[in]levelSeverity 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.

◆ parseBody()

virtual bool ts::HEVCSequenceParameterSet::parseBody ( AVCParser parser,
std::initializer_list< uint32_t >  params 
)
overrideprotectedvirtual

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]parserThe parser of an AVC-like video stream.
[in]paramsAdditional parameters. May be needed by some structures.
Returns
The valid flag.

Implements ts::AbstractVideoAccessUnit.

◆ parseHeader()

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

Parse the header of the access unit.

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

Parameters
[in,out]addrAddress of the binary data to parse. Adjusted after header.
[in,out]sizeSize in bytes of the binary data to parse. Adjusted as remaining size after header.
[in]paramsAdditional 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]addrAddress of the binary data to parse.
[in]sizeSize in bytes of the binary data to parse.
[in]paramsAdditional parameters. May be needed by some structures.
Returns
The valid flag.

Implements ts::AbstractVideoData.

◆ 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
INTAn integer type.
Parameters
[in,out]outThe stream where to print the content.
[in]marginThe prefix string on each line.
[in]nameA name to display for the value.
[in]nThe 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
INTAn integer type.
Parameters
[in,out]outThe stream where to print the content.
[in]marginThe prefix string on each line.
[in]nameA name to display for the value.
[in]nThe integer values to display.
