슬라이더라고 해야하려나?
그거 추가하는 내용
그나저나.. 2.4.11.0 문서인데 왜 cpp가 아니라 c로 된게 있지 -ㅁ-?

클릭할 경우 마우스 이벤트에서 좌표가 나오는군..
윈도우 사이즈랑은 따로 구해야 하려나?..

예전에 받아둔걸로 다시 해보는데..
음.. 비디오가 몇개 있는진 알 수 없다 인가?!
새로운 API가 나오기 전까지는 일일이 open 해보고 리턴값으로 체크해야 할 듯..

못 불러 오는 설정사항도 많다 -_-a
| VideoCapture::get C++: double VideoCapture::get(int propId) C: double cvGetCaptureProperty(CvCapture* capture, int property_id) – CV_CAP_PROP_RECTIFICATION Rectification flag for stereo cameras (note: only supported by DC1394 v 2.x backend currently)
propId – Property identifier. It can be one of the following:
– CV_CAP_PROP_POS_MSEC Current position of the video file in milliseconds or video capture timestamp.
– CV_CAP_PROP_POS_FRAMES 0-based index of the frame to be decoded/captured next.
– CV_CAP_PROP_POS_AVI_RATIO Relative position of the video file: 0 - start of the film, 1 - end of the film.
– CV_CAP_PROP_FRAME_WIDTH Width of the frames in the video stream.
– CV_CAP_PROP_FRAME_HEIGHT Height of the frames in the video stream.
– CV_CAP_PROP_FPS Frame rate.
– CV_CAP_PROP_FOURCC 4-character code of codec.
– CV_CAP_PROP_FRAME_COUNT Number of frames in the video file.
– CV_CAP_PROP_FORMAT Format of the Mat objects returned by retrieve() .
– CV_CAP_PROP_MODE Backend-specific value indicating the current capture mode.
– CV_CAP_PROP_BRIGHTNESS Brightness of the image (only for cameras).
– CV_CAP_PROP_CONTRAST Contrast of the image (only for cameras).
– CV_CAP_PROP_SATURATION Saturation of the image (only for cameras).
– CV_CAP_PROP_HUE Hue of the image (only for cameras).
– CV_CAP_PROP_GAIN Gain of the image (only for cameras).
– CV_CAP_PROP_EXPOSURE Exposure (only for cameras).
– CV_CAP_PROP_CONVERT_RGB Boolean flags indicating whether images should be converted to RGB.
– CV_CAP_PROP_WHITE_BALANCE Currently not supported

나중에 색상 조절해서 채널별로 출력을 해봐야겠다

일단.. #if 로 막은 아래소스를 사용한건데
2.3.1에서는 문제없이 되는 것을 봐서는 윈도우에서 라이브러리 버전이 꼬였거나 먼가 설정 문제인 듯 하다.
