Alexey Nikolaev	8396ae6e4f	Merge pull request #12893 from aleksey-nikolaev:cap-update V4L (V4L2): Refactoring. Added missed camera properties. Fixed getting `INF` for some properties. Singlethread as always (#12893) * cap_v4l: 1 Added cap_properties verbalization. 2 Set Get of properties elementary refactoring. 3 Removed converting parameters to/from [0,1] range. 4 Added all known conversion from V4L2_CID_* to CV_CAP_PROP_* * cap_v4l: 1. Removed all query for parameters range. 2. Refactored capture initialization. 3. Added selecting input channel by CV_CAP_PROP_MODE. Default value -1 the channels not changed. * cap_v4l: 1. Refactoring of Convert To RGB * cap_v4l: 1. Fixed use of video buffer index. 2. Removed extra memcopy for grab image. 3. Removed device closing from autosetup_capture_mode_v4l2 * cap_v4l: 1. The `goto` was eliminated 2. Fixed use of temporary buffer index for V4L2_PIX_FMT_SN9C10X 3. Fixed use of the bufferIndex 4. Removed trailing spaces and unused variables. * cap_v4l: 1. Alias for capture->buffers[capture->bufferIndex] 2. Reduced size of data for memcpy: bytesused instead of length 3. Refactoring. Code duplication. More info for debug * cap_v4l: 1. Added the ability to grab and retrieveFrame independently several times * cap_v4l: 1. Not need to close/open device for new capture parameters applying. 2. Removed using of device name as a flag that the capture is closed. Added sufficient function. 3. Refactoring. Added requestBuffers and createBuffers * cap_v4l: 1. Added tryIoctl with `select` like was in mainloop_v4l2. 2. Fixed buffer request for device without closing the device. 3. Some static function moved to CvCaptureCAM_V4L 4. Removed unused defines * cap_v4l: 1. Thread-safe now * cap_v4l: 1. Fixed thread-safe destructor 2. Fixed FPS setting * Missed brake * Removed thread-safety * cap_v4l: 1. Reverted conversion parameters to/from [0,1] by default for backward compatibility. 2. Added setting for turn off compatibility mode: set CV_CAP_PROP_MODE to 65536 3. Most static functions moved to CvCaptureCAM_V4L 4. Refactoring of icvRetrieveFrameCAM_V4L and using of frame_allocated flag * cap_v4l: 1. Added conversion to RGB from NV12, NV21 2. Refactoring. Removed wrappers for known format conversions. * Added `CAP_PROP_CHANNEL` to the enum VideoCaptureProperties. CAP_V4L migrated to use VideoCaptureProperties. * 1. Update comments. 2. Environment variable `OPENCV_VIDEOIO_V4L_RANGE_NORMALIZED` for setting default backward compatibility mode. 3. Revert getting of `CAP_PROP_MODE` as fourcc code in backward compatibility mode. * videoio: update cap_v4l - compatibilityMode => normalizePropRange * videoio(test): V4L2 MJPEG test `v4l2-ctl --list-formats` should have 'MJPG' entry * videoio: fix buffer initialization to avoid "munmap: Invalid argument" messages	6 years ago
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
