Member Typedef Documentation

◆ SuperClass

Reference to the superclass.

Constructor & Destructor Documentation

◆ AVCAccessUnitDelimiter()

ts::AVCAccessUnitDelimiter::AVCAccessUnitDelimiter ( 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::AVCAccessUnitDelimiter::clear ( )
overridevirtual

Clear all values. Should be reimplemented by subclasses. The data are marked invalid.

Reimplemented from ts::AbstractAVCAccessUnit.

◆ display()

virtual std::ostream & ts::AVCAccessUnitDelimiter::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.

◆ parseBody()

virtual bool ts::AVCAccessUnitDelimiter::parseBody ( AVCParser & parser,
std::initializer_list< uint32_t > params = std::initializer_list< uint32_t >() )
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::AbstractAVCAccessUnit::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>
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
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>
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
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.
