class CVD::ReadAheadVideoBuffer< T >
Decorator video buffer that preloads frames asynchronously in a separate thread.
- Parameters:
-
T The pixel type of the video frames vb The video buffer to wrap/preload maxReadAhead The maximum number of frames to read ahead asynchronously; the underlying VideoBuffer must support this many concurrently existing VideoFrame's

template<class T >
| void CVD::ReadAheadVideoBuffer< T >::put_frame | ( | VideoFrame< 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< T >.

template<class T >
| void CVD::ReadAheadVideoBuffer< T >::seek_to | ( | double | t | ) | [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
Reimplemented from CVD::RawVideoBuffer.
