Detailed Description
template<class pixel_T>
class CVD::DVBuffer3< pixel_T >
A video buffer from a Firewire (IEEE 1394) camera.
This can use both v1.x and v2.0 series of libdc1394. For v2 it selects the video mode as described for RawDVBuffer3 above. For v1 this just wraps DVBuffer2.

| virtual void CVD::DVBuffer3< pixel_T >::put_frame | ( | VideoFrame< pixel_T > * | f | ) | [inline, virtual] |
Tell the buffer that you are finished with this frame.
Typically the VideoBuffer then destroys the frame.
- Parameters:
-
f The frame that you are finished with.
Implements CVD::VideoBuffer< pixel_T >.

| virtual bool CVD::DVBuffer3< pixel_T >::frame_pending | ( | ) | [inline, virtual] |
Is there a frame waiting in the buffer? This function does not block.
See is_live and is_flushable.
Reimplemented from CVD::DV3::RawDVBuffer3.
Definition at line 204 of file dvbuffer3.h.
| virtual void CVD::DVBuffer3< pixel_T >::seek_to | ( | double | ) | [inline, virtual] |
Go to a particular point in the video buffer (only implemented in buffers of recorded video)
- Parameters:
-
t The frame time in seconds
