Public Member Functions | |
Media_PlayerContext (Media_IFrameQueue *theFrameQueue) | |
Main constructor. Note that Frame Queue is stored as pointer, and it is expected that this context is stored as a class field of Frame Queue. | |
virtual | ~Media_PlayerContext () |
Destructor. | |
void | SetInput (const TCollection_AsciiString &theInputPath, Standard_Boolean theToWait) |
Set new input for playback. | |
void | PlaybackState (Standard_Boolean &theIsPaused, Standard_Real &theProgress, Standard_Real &theDuration) |
Return playback state. | |
void | PlayPause (Standard_Boolean &theIsPaused, Standard_Real &theProgress, Standard_Real &theDuration) |
Pause/Pause playback depending on the current state. | |
void | Seek (Standard_Real thePosSec) |
Seek to specified position. | |
void | Pause () |
Pause playback. | |
void | Resume () |
Resume playback. | |
bool | ToForceRgb () const |
Return TRUE if queue requires RGB pixel format or can handle also YUV pixel format; TRUE by default. | |
void | SetForceRgb (bool theToForce) |
Set if queue requires RGB pixel format or can handle also YUV pixel format. | |
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 () |
Destructor must be virtual. | |
virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
Returns a type descriptor about this object. | |
Standard_Boolean | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
Returns a true value if this is an instance of Type. | |
Standard_Boolean | IsInstance (const Standard_CString theTypeName) const |
Returns a true value if this is an instance of TypeName. | |
Standard_Boolean | 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. | |
Standard_Boolean | IsKind (const Standard_CString 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. | |
Standard_Integer | GetRefCount () const noexcept |
Get the reference counter of this object. | |
void | IncrementRefCounter () noexcept |
Increments the reference counter of this object. | |
Standard_Integer | DecrementRefCounter () noexcept |
Decrements the reference counter of this object; returns the decremented value. | |
virtual void | Delete () const |
Memory deallocator for transient classes. | |
Static Public Member Functions | |
static Handle< Media_Frame > | DumpFirstFrame (const TCollection_AsciiString &theSrcVideo, TCollection_AsciiString &theMediaInfo) |
Dump first video frame. | |
static bool | DumpFirstFrame (const TCollection_AsciiString &theSrcVideo, const TCollection_AsciiString &theOutImage, TCollection_AsciiString &theMediaInfo, int theMaxSize=0) |
Dump first video frame. | |
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. | |
Additional Inherited Members | |
Public Types inherited from Standard_Transient | |
