| virtual VideoFrame<T>* CVD::V4L2BufferT< T >::get_frame | ( | ) | [inline, virtual] |
Returns the next frame from the buffer. This function blocks until a frame is ready.

| virtual void CVD::V4L2BufferT< T >::put_frame | ( | VideoFrame< T > * | f | ) | [inline, virtual] |
Tell the buffer that you are finished with this frame. Overloaded version of VideoBuffer<T>::put_frame().
Implements CVD::VideoBuffer< T >.

| virtual bool CVD::V4L2BufferT< T >::frame_pending | ( | ) | [inline, virtual] |
Is there a frame waiting in the buffer? This function does not block.
See is_live and is_flushable.

| virtual double CVD::V4L2BufferT< T >::frame_rate | ( | ) | [inline, virtual] |
What is the (expected) frame rate of this video buffer, in frames per second?
