Decorator video buffer that preloads frames asynchronously in a separate thread.
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 |

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.
f | The frame that you are finished with. |
Implements CVD::VideoBuffer< 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)
t | The frame time in seconds |
Reimplemented from CVD::RawVideoBuffer.
