Member Function Documentation

virtual bool CVD::O2Buffer::frame_pending

(

)

[virtual]

Is there a frame waiting in the buffer? This function does not block. See is_live and is_flushable.

Implements CVD::RawVideoBuffer.

virtual double CVD::O2Buffer::frame_rate

(

)

[virtual]

What is the (expected) frame rate of this video buffer, in frames per second?

Implements CVD::RawVideoBuffer.

virtual O2VideoFrame* CVD::O2Buffer::get_frame

(

)

[virtual]

Returns the next frame from the buffer. This function blocks until a frame is ready.

Implements CVD::VideoBuffer< Rgb8 >.

virtual void CVD::O2Buffer::put_frame

(

VideoFrame< Rgb8 > *

f

)

[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< Rgb8 >.

virtual ImageRef CVD::O2Buffer::size

(

)

[virtual]

The size of the VideoFrames returned by this buffer.

Implements CVD::RawVideoBuffer.
