自己最近做一个项目，采用Opencv2.4.10+MFC处理，结果发现，在视频处理过程中，采用bool VideoCapture::set(int propId, double value)函数设置图像的分辨率，返回值为0，查看opencv2.4.10文档，是这样的

propId – Property identifier. It can be one of the following:
– CV_CAP_PROP_POS_MSEC Current position of the video file in milliseconds.
– 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 unsupported
– CV_CAP_PROP_RECTIFICATION Rectification flag for stereo cameras (note: only
supported by DC1394 v 2.x backend currently)
value – Value of the property.

文档中并没有明确视频帧的宽度，高度仅仅适合摄像头或是视频，于是我用

CV_CAP_PROP_FRAME_WIDTH，CV_CAP_PROP_FRAME_HEIGHT设置视频帧的分辨率，结果

结果发现，设置无效，于是总结出目前的opencv版本不支持视频帧

分辨率设置。
