Member Function Documentation

SimTime DC1394Grabber2::getNaturalFrameTime ( ) const [virtual]

Get the inter-frame time that matches our video mode.

Reimplemented from FrameIstream.

Definition at line 453 of file DC1394Grabber2.C.

References OModelParam< T >::getVal(), and SimTime::HERTZ().

VideoFrame DC1394Grabber2::grabRaw ( ) [protected]

Grab raw data.

Don't call this directly; use readFrame() instead.

Definition at line 465 of file DC1394Grabber2.C.

References OModelParam< T >::getVal().

Referenced by readFrame().

GenericFrameSpec DC1394Grabber2::peekFrameSpec ( ) [virtual]

Return the specifications of the next frame to be returned.

Implements FrameIstream.

Definition at line 439 of file DC1394Grabber2.C.

References OModelParam< T >::getVal().

GenericFrame DC1394Grabber2::readFrame ( ) [virtual]

Get the next frame from the frame-grabber.

Returns grabbed frame. This call will block until a frame is ready and has been grabbed.

Beware that the integrity of the GenericFrame object may not last "very long"; basically, try to be finished using the GenericFrame object before you attempt to grab the next frame in the stream. If you need it for longer than that, then you should use GenericFrame::deepCopyOf() to make a copy of the frame that can be safely held indefinitely.

Implements FrameIstream.
