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

Peter Rekdal Sunde	042c486b68	Obtain fourcc when `AVStream` is network stream The `codec_tag` is only available when opening a file from disk. If `AVStream` is a network stream then `fourcc` must be obtained using `codec_id`. I have tested the following scenarios: 1) Open a `.mp4` file and verify that `codec_tag` is returned (old behavior) 2) Open a `rtsp` stream and verify that `codec_fourcc` is returned (Tested with a MJPEG, H264 and H265 stream)	6 years ago

Todor Tomov	9988e1b6ee	cap_v4l: Fix private control enumeration end condition Currently the private control enumeration will be stopped when QUERYCTRL returns -EINVAL only. It is possible however that other errors occur. One particular case is when the v4l2 device doesn't support any controls and doesn't implement the QUERYCTRL ioctl. In that case the v4l2 framework returns -ENOTTY. In that case the current control enumeration will go in an endless loop. To fix this change the control enumeration stop condition. If any errors occur, end the control enumeration. Signed-off-by: Todor Tomov <todor.tomov@linaro.org>	6 years ago

Jakub Golinowski	9f1218b00b	Merge pull request #11897 from Jakub-Golinowski:hpx_backend * Add HPX backend for OpenCV implementation Adds hpx backend for cv::parallel_for_() calls respecting the nstripes chunking parameter. C++ code for the backend is added to modules/core/parallel.cpp. Also, the necessary changes to cmake files are introduced. Backend can operate in 2 versions (selectable by cmake build option WITH_HPX_STARTSTOP): hpx (runtime always on) and hpx_startstop (start and stop the backend for each cv::parallel_for_() call) * WIP: Conditionally include hpx_main.hpp to tests in core module Header hpx_main.hpp is included to both core/perf/perf_main.cpp and core/test/test_main.cpp. The changes to cmake files for linking hpx library to above mentioned test executalbles are proposed but have issues. * Add coditional iclusion of hpx_main.hpp to cpp cpu modules * Remove start/stop version of hpx backend	6 years ago
