Member Function Documentation

bool moGsFramework::AddCaptureDevice ( moCaptureDevice &  p_capdev )

virtual

Agrega un dispositivo de video.

Si el dispositivo existe entonces esta función devuelve verdadero.

Returns

verdadero si existe y pudo ser agregado, falso si no

try to load: then if couldn't load it return false....

Implements moVideoFramework.

Definition at line 1423 of file moGsGraph.cpp.

bool moGsFramework::CheckCaptureDevice ( int  i )

virtual

Chequea si el dispositivos de video disponible está aún disponible.

En el indice i del arreglo de los dispositivos de video disponibles confirma la disponibilidad de este. Al implementar esta función se puede conectar y reconectar cámaras.

Returns

verdadero si está disponible, falso si no

TODO: implement CheckCaptureDevice
