Public Member Functions | |
| void | flush () |
| bool | frame_pending () |
| double | frame_rate () |
| What is the (expected) frame rate of this video buffer, in frames per second? | |
| VideoFrame< T > * | get_frame () |
| Returns the next frame from the buffer. This function blocks until a frame is ready. | |
| void | put_frame (VideoFrame< T > *f) |
| double | seek_to () |
| ImageRef | size () |
| The size of the VideoFrames returned by this buffer. | |

Public Attributes | |

Private Attributes | |
| std::auto_ptr< VideoBuffer< T > > | buf |
Certain video buffers, especially the decorator classes, and buffers such as ServerPushJpegBuffer have additional data with the same lifetime as the buffer. This is a tool to allow management of this data. This class manages a video buffer and some data concurrently.
| T | The pixel type of the video frames |

| void CVD::VideoBufferWithData< T, D >::flush | ( | ) | [inline, virtual] |
Flush all old frames out of the video buffer, on a flushable buffer, causing the next get_frame() to sleep until a frame arrives. On a non-flushable buffer, this does nothing.
Reimplemented from CVD::VideoBuffer< T >.

| bool CVD::VideoBufferWithData< T, D >::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.

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

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

| void CVD::VideoBufferWithData< T, D >::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. |

| ImageRef CVD::VideoBufferWithData< T, D >::size | ( | ) | [inline, virtual] |
The size of the VideoFrames returned by this buffer.
Implements CVD::RawVideoBuffer.

| virtual RawVideoBuffer* CVD::VideoBufferWithData< T, D >::source_buffer | ( | ) | [inline, virtual] |
Which video grabber provides the source images for this video grabber.
