 Public Member Functions inherited from CVD::RawVideoBuffer | |
| virtual RawVideoBuffer * | source_buffer () |
| Which video grabber provides the source images for this video grabber. More... | |
| RawVideoBuffer * | root_buffer () |
| Follow the chain of video grabbers back as far as at will go. More... | |
| virtual ImageRef | size ()=0 |
| The size of the VideoFrames returned by this buffer. | |
| virtual bool | frame_pending ()=0 |
| Is there a frame waiting in the buffer? This function does not block. More... | |
| virtual double | frame_rate ()=0 |
| What is the (expected) frame rate of this video buffer, in frames per second? | |
| virtual void | seek_to (double) |
| Go to a particular point in the video buffer (only implemented in buffers of recorded video) More... | |
| virtual void | flush ()=0 |
| Flush all old frames out of the video buffer, on a flushable buffer, causing the next get_frame() to sleep until a frame arrives. More... | |
