template<class T >
| virtual void CVD::V4LBuffer< 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.

| virtual bool CVD::V4LBuffer< T >::frame_pending | ( | ) | [inline, virtual] |
Is there a frame waiting in the buffer? This function does not block.
See is_live and is_flushable.
Implements CVD::RawVideoBuffer.
