How to set camera format in OpenCV
VideoCapture cap(0); // open the default camera
if(!cap.isOpened()) // check if we succeeded
return -1;
// set frame size to 320x240 pix
cap.set(CV_CAP_PROP_FRAME_WIDTH,320);
cap.set(CV_CAP_PROP_FRAME_HEIGHT,240);
double grabMode,frameFormat,settings;
bool ok = false;
// Backed-specific value indicating the current capture mode.
grabMode = cap.get(CV_CAP_PROP_MODE);
// Format of the Mat objects returned by retrieve()
frameFormat = cap.get(CV_CAP_PROP_FORMAT);
// Some available settings
settings = cap.get(CV_CAP_PROP_SETTINGS);
// Playing around GRAB_MODE
// Boolean flags indicating whether images should be converted to RGB.
cap.set(CV_CAP_PROP_CONVERT_RGB, 0);
int i = -100;
while(ok == false && i<10)
{
if (i != 0)
ok = cap.set(CV_CAP_PROP_MODE, grabMode + i);
i++;
}
if(ok)
{
grabMode = cap.get(CV_CAP_PROP_MODE);
cout << "Grab Mode=" << grabMode << " is supported" << endl;
}
VideoCapture::get
Returns the specified VideoCapture property
C++: double VideoCapture::get(int propId)
Python: cv2.VideoCapture.get(propId) → retval
C: double cvGetCaptureProperty(CvCapture* capture, int property_id)
Python: cv.GetCaptureProperty(capture, property_id) → float
Parameters: 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_U The U value of the whitebalance setting (note: only supported by DC1394 v 2.x backend currently)
CV_CAP_PROP_WHITE_BALANCE_V The V value of the whitebalance setting (note: only supported by DC1394 v 2.x backend currently)
CV_CAP_PROP_RECTIFICATION Rectification flag for stereo cameras (note: only supported by DC1394 v 2.x backend currently)
CV_CAP_PROP_ISO_SPEED The ISO speed of the camera (note: only supported by DC1394 v 2.x backend currently)
CV_CAP_PROP_BUFFERSIZE Amount of frames stored in internal buffer memory (note: only supported by DC1394 v 2.x backend currently)
Note: When querying a property that is not supported by the backend used by the VideoCapture class, value 0 is returned.
VideoCapture::set
Sets a property in the VideoCapture.
C++: bool VideoCapture::set(int propId, double value)
Python: cv2.VideoCapture.set(propId, value) → retval
C: int cvSetCaptureProperty(CvCapture* capture, int property_id, double value)
Python: cv.SetCaptureProperty(capture, property_id, value) → retval
