How do I get usb webcam property IDs for OpenCV
I want to lock the focus on my USB webcam I\'m using with OpenCV but how do I find the Property ID numbers for that webcam so I can set them.

In
C/C++documentation Flags for video I/O in sectionenum cv::VideoCapturePropertiesyou can find values and names ie.cv::CAP_PROP_FRAME_WIDTH =3,For python it will be
cv2.CAP_PROP_FRAME_WIDTH = 3what you can check with
print(cv2.CAP_PROP_FRAME_WIDTH)
All values from this page
cv2.CAP_PROP_POS_MSEC = 0 cv2.CAP_PROP_POS_FRAMES = 1 cv2.CAP_PROP_POS_AVI_RATIO = 2 cv2.CAP_PROP_FRAME_WIDTH = 3 cv2.CAP_PROP_FRAME_HEIGHT = 4 cv2.CAP_PROP_FPS = 5 cv2.CAP_PROP_FOURCC = 6 cv2.CAP_PROP_FRAME_COUNT = 7 cv2.CAP_PROP_FORMAT = 8 cv2.CAP_PROP_MODE = 9 cv2.CAP_PROP_BRIGHTNESS = 10 cv2.CAP_PROP_CONTRAST = 11 cv2.CAP_PROP_SATURATION = 12 cv2.CAP_PROP_HUE = 13 cv2.CAP_PROP_GAIN = 14 cv2.CAP_PROP_EXPOSURE = 15 cv2.CAP_PROP_CONVERT_RGB = 16 cv2.CAP_PROP_WHITE_BALANCE_BLUE_U = 17 cv2.CAP_PROP_RECTIFICATION = 18 cv2.CAP_PROP_MONOCHROME = 19 cv2.CAP_PROP_SHARPNESS = 20 cv2.CAP_PROP_AUTO_EXPOSURE = 21 cv2.CAP_PROP_GAMMA = 22 cv2.CAP_PROP_TEMPERATURE = 23 cv2.CAP_PROP_TRIGGER = 24 cv2.CAP_PROP_TRIGGER_DELAY = 25 cv2.CAP_PROP_WHITE_BALANCE_RED_V = 26 cv2.CAP_PROP_ZOOM = 27 cv2.CAP_PROP_FOCUS = 28 cv2.CAP_PROP_GUID = 29 cv2.CAP_PROP_ISO_SPEED = 30 cv2.CAP_PROP_BACKLIGHT = 32 cv2.CAP_PROP_PAN = 33 cv2.CAP_PROP_TILT = 34 cv2.CAP_PROP_ROLL = 35 cv2.CAP_PROP_IRIS = 36 cv2.CAP_PROP_SETTINGS = 37 cv2.CAP_PROP_BUFFERSIZE = 38 cv2.CAP_PROP_AUTOFOCUS = 39 cv2.CAP_PROP_SAR_NUM = 40 cv2.CAP_PROP_SAR_DEN = 41 cv2.CAP_PROP_BACKEND = 42 cv2.CAP_PROP_CHANNEL = 43 cv2.CAP_PROP_AUTO_WB = 44 cv2.CAP_PROP_WB_TEMPERATURE = 45 cv2.CAP_PROP_CODEC_PIXEL_FORMAT = 46 cv2.CAP_PROP_BITRATE = 47 cv2.CAP_PROP_ORIENTATION_META = 48 cv2.CAP_PROP_ORIENTATION_AUTO = 49
On the same page but little lower you can see VideoCaptureProperties with information
VideoCapture generic properties identifier. Reading / writing properties involves many layers. Some unexpected result might happens along this chain. Effective behaviour depends from device hardware, driver and API Backend.Which can means that these values are universal for all devices but some of devices or codecs/drivers may not have some values.
There is also link Additional flags for video I/O API backends with properties only for some codes/drivers.
On page Video I/O with OpenCV Overview you can also see
Each backend supports devices properties (cv::VideoCaptureProperties) in a different way or might not support any property at all.
BTW:
Python's names (but without numbers) are also in doc for old version 2.4: VideoCapture::get
In much older versions Python was using little different names - ie.
cv2.cv.CV_CAP_PROP_FRAME_WIDTH cv2.cv.CV_CAP_PROP_FRAME_HEIGHT
EDIT:
I made program to list all properties sorted by values.
If you skip
sorted()then you get sorted by names.import cv2 properties = [] for name in dir(cv2): if name.startswith('CAP_PROP'): value = getattr(cv2, name) properties.append((value, name)) # it will sort by values # originally it is sorted by names properties = sorted(properties) for value, name in properties: print(f' {value:5} | cv2.{name}')Sorted by values:
