wanghanmin	eb981cc7d7	Merge pull request #12138 from wanghanmin:wanghanmin-patch-videoio_crossbarsetting-1 * Update videoio.hpp add VideoCapturePropertie for clossbar input pin setting * Update cap_dshow.cpp For some kind of capture card, such as "avermedia cv710 " , it use SerialDigital as input pin and so it can not work. Here added new PhysicalConnectorType enumeration: PhysConn_Video_YRYBY and PhysConn_Video_SerialDigital to support it. And also provide new property parameter CAP_CROSSBAR_INPIN_TYPE to set the crossbar input pin type which will be used in videoInput::start(int deviceID, videoDevice VD): " if(VD->useCrossbar) { DebugPrintOut("SETUP: Checking crossbar\n"); routeCrossbar(&VD->pCaptureGraph, &VD->pVideoInputFilter, VD->connection, CAPTURE_MODE); } " And at last ,fixed one issue for function setSizeAndSubtype, added code pVih->rcSource.top = pVih->rcSource.left = pVih->rcTarget.top =pVih->rcTarget.left=0; pVih->rcSource.right = pVih->rcTarget.right= attemptWidth; pVih->rcSource.bottom = pVih->rcTarget.bottom = attemptHeight; without these code , rcSource and rcTarget will keeping use default resolution and cause fail in hr = VD->streamConf->SetFormat(VD->pAmMediaType) and cannot find suitable MediaType. Tested with python3 and mfc (Avermedia cv710) Python3 code: import cv2 print("test cv") cap=cv2.VideoCapture(0) cap.set(5,60) cap.set(3,1920) cap.set(4,1080) cap.set(31,6) ret,img=cap.read() cv2.namedWindow("cap",cv2.WINDOW_NORMAL) cv2.resizeWindow("cap",960,640); while True: ret,img=cap.read() if ret==False: continue cv2.imshow("cap",img) if cv2.waitKey(1) & 0xFF == ord('q'): break cap.release() cv2.destroyAllWindows() MFC code: void CcvtestDlg::OnBnClickedButton1() { VideoCapture cap(0); cap.set(CAP_PROP_FRAME_WIDTH, 1920); cap.set(CAP_PROP_FRAME_HEIGHT, 1080); cap.set(CAP_CROSSBAR_INPIN_TYPE , 6); Mat img; namedWindow("test", WINDOW_NORMAL); resizeWindow("test", 960, 640); while (1) { if (cap.read(img)) { imshow("test", img); if ('q' ==waitKey(1)) break; } } destroyAllWindows(); cap.release(); } Update cap_dshow.cpp * Update videoio.hpp move enum value of CAP_CROSSBAR_INPIN_TYPE to the end of list * Update videoio.hpp * Update cap_dshow.cpp removed trailing whitespace * Update test_camera.cpp Add test for capture device using PhysConn_Video_SerialDigital as crossbar input pin * Update test_camera.cpp Correction of misunderstanding about how to add test case.	6 years ago

Valeriy Van	f1dcf71dd7	Merge pull request #7178 from valeriyvan:iosfixes * Changes delegate property from assign to weak In modern Objective-C delegate should be weak. In very rare conditions you might want delegate be strong. Assign for delegate is sign of legacy code. This change prevents crash when you forget nil delegate in dealloc and makes rush with nilling delegate unnecessary. This change shouldn't break any existing code. * Adds implementation for setters and getters for weak delegate properties for non ARC Obj-C files For whatever reason compiler can't synthesize these. And yes, it's time to convert all Objective-C stuff to ARC.	8 years ago
