Merge pull request #20978 from cudawarped:videocapture_read_raw_enchancement
Add capacity to Videocapture to return the extraData from FFmpeg when required

* Update rawMode to append any extra data recieved during the initial negotiation of an RTSP stream or during the parsing of an MPEG4 file header.
For h264[5] RTSP streams this ensures the parameter sets if available are always returned on the first call to grab()/read() and has two purposes:
1) To ensure the parameter sets are available even if they are not transmitted in band.  This is common for axis ip camera's.
2) To allow callers of VideoCapture::grab()[read()] to write to split the raw stream over multiple files by appending the parameter sets to the begining of any new files.
For (1) there is no alternative, for (2) if the parameter sets were provided in band it would be possible to parse the raw bit stream and search for the parameter sets however that would be a lot of work when that information is already provided by FFMPEG.
For MPEG4 files this information is only suplied in the header and is required for decoding.

Two properties are also required to enable the raw encoded bitstream to be written to multiple files, these are;
1) an indicator as to whether the last frame was a key frame or not - each new file needs to start at a key frame to avoid storing unusable frame diffs,
2) the length in bytes of the paramater sets contained in the last frame - required to split the paramater sets from the frame without having to parse the stream.  Any call to VideoCapture::get(CAP_PROP_LF_PARAM_SET_LEN) returning a number greater than zero indicates the presense of a parameter set at the begining of the raw bitstream.

* Adjust test data to account for extraData

* Address warning.

* Change added property names and remove paramater set start code check.

* Output extra data on calls to retrieve instead of appending to the first packet.

* Reverted old test case and added new one to evaluate new functionality.

* Add missing definition.

* Remove flag from legacy api.
Add property to determine if returning extra data is supported.
Always allow extra data to be returned on calls to cap.retrieve()
Update test case.

* Update condition which indicates CAP_PROP_CODEC_EXTRADATA_INDEX is not supported in test case.

* Include compatibility for windows dll if not updated.
Enforce existing return status convention.

* Fix return error and missing test constraints.

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:

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

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.

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
