Inheritance diagram for Media_Packet:

Public Member Functions
	Media_Packet ()
	Empty constructor.
	~Media_Packet () override
	Destructor.
void	Unref ()
	av_packet_unref() wrapper.
const AVPacket *	Packet () const
	Return packet.
AVPacket *	ChangePacket ()
	Return packet.
const uint8_t *	Data () const
	Return data.
uint8_t *	ChangeData ()
	Return data.
int	Size () const
	Return data size.
int64_t	Pts () const
	Return presentation timestamp (PTS).
int64_t	Dts () const
	Return decoding timestamp (DTS).
int64_t	Duration () const
	Return Duration.
double	DurationSeconds () const
	Return Duration in seconds.
void	SetDurationSeconds (double theDurationSec)
	Set Duration in seconds.
int	StreamIndex () const
	Return stream index.
bool	IsKeyFrame () const
	Return TRUE for a key frame.
void	SetKeyFrame ()

Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.
	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.
Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.
virtual	~Standard_Transient ()=default
	Destructor must be virtual.
virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.
bool	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.
bool	IsInstance (const char *const theTypeName) const
	Returns a true value if this is an instance of TypeName.
bool	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
bool	IsKind (const char *const theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
int	GetRefCount () const noexcept
	Get the reference counter of this object.
void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
virtual void	Delete () const
	Memory deallocator for transient classes.

Protected Attributes
AVPacket *	myPacket
	packet
double	myDurationSec
	packet duration in seconds

Additional Inherited Members
Public Types inherited from Standard_Transient
typedef void	base_type
	Returns a type descriptor about this object.
Static Public Member Functions inherited from Standard_Transient
static constexpr const char *	get_type_name ()
	Returns a type descriptor about this object.
static const opencascade::handle< Standard_Type > &	get_type_descriptor ()
	Returns type descriptor of Standard_Transient class.
