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.
Member Function Documentation
◆ frame_pending()
template<class pixel_T >
|
inlinevirtual |
Is there a frame waiting in the buffer? This function does not block.
See is_live and is_flushable.
Reimplemented from CVD::DV3::RawDVBuffer3.
◆ put_frame()
template<class pixel_T >
|
inlinevirtual |
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 >.
◆ seek_to()
template<class pixel_T >
|
inlinevirtual |
Go to a particular point in the video buffer (only implemented in buffers of recorded video)
- Parameters
-
t The frame time in seconds
Reimplemented from CVD::RawVideoBuffer.
The documentation for this class was generated from the following file:
- cvd/Linux/dvbuffer3.h
