IMObject

Operates objects.

Methods

ObjectCallbackSet

Sets the callback (for C++ and Delphi, for other languages use events). This method blocks the video stream.

Syntax

void ObjectCallbackSet( 
   IMCallback _pCallback,
   long _llCallbackUserData
)

Parameters

_pCallback - callback function
_llCallbackUserData - callback user data

ObjectCallbackSetFunc

Sets the callback function (for C++ and Delphi, for other languages use events). The method blocks the video stream.

Syntax

void ObjectCallbackSetFunc( 
   long _lpPFOnEvent,
   long _lpPFOnFrame,
   long _llCallbackUserData
)

Parameters

_lpPFOnEvent - function pointer OnEvent
_lpPFOnFrame - function pointer OnFrame
_llCallbackUserData - callback user data

ObjectClose

Stops and closes the current object.

Syntax

void ObjectClose()

ObjectCommandExecute

Executes the special command for object.

Syntax

void ObjectCommandExecute( 
   string _bsCommand,
   string _bsParam,
   object _pParamUnk,
   out string _pbsReturn
)

Parameters

_bsCommand - command name
_bsParam - command parameters
_pParamUnk - additional command parameters
_pbsReturn - result string

ObjectFrameGet

Gets the current frame from any source object.

Syntax

void ObjectFrameGet( 
   out MFrame _ppFrame,
   string _bsParam
)

Parameters

_ppFrame - output frame object
_bsParam - additional parameters: make_local - "true" to convert frame to ARGB32 format (by default, for other formats you should set pixel_format parameter); "false" to left the current format pixel_format - format for frame conversion (ARGB32/YVYU/HDYC)

ObjectGetInternal

Gets DirectShow object in MPlatform. Use for MLive, MRenderer and MWriter objects.

Syntax

void ObjectGetInternal( 
   string _bsType,
   out object _ppObject
)

Parameters

_bsType - object type
_ppObject - pointer to the object

ObjectNameGet

Gets the object name.

Syntax

void ObjectNameGet( 
   out string _pbsName
)

Parameters

_pbsName - name of the object

ObjectNameSet

Sets the object name. If you need to change it, use the following approach:

IMObject.PropsSet("object_name", "new_name");

IMObject.ObjectNameSet("new_name");

Note, that it's possible to change the name only before the object is started. If the object is running, stop it, and only then rename the object.

Syntax

void ObjectNameSet( 
   string _bsName
)

Parameters

_bsName - name of the object

ObjectStart

Initializes and starts the object.

Syntax

void ObjectStart( 
   object _pSource
)

Parameters

_pSource - source object

ObjectStateGet

Gets the state of object.

Syntax

void ObjectStateGet( 
   out eMState _peState
)

Parameters

_peState - state of the object

ObjectVirtualSourceCreate

Creates virtual source.

Syntax

void ObjectVirtualSourceCreate( 
   int _bCreate,
   string _bsName,
   string _bsParam
)

Parameters

_bCreate - "1" is to create virtual source, "0" is to destroy this one
_bsName - name of virtual source. It is implemented only is source object is started. In other case a default name is used that may cause a problem if you use several virtual objects.
_bsParam - parameters of virtual source
