Philippe FOUBERT	43a1874e33	Bug correction: The "CvCaptureCAM_XIMEA::getProperty" method had not the same signature as "CvCapture::getProperty" so it was not called when we use the "VideoCapture::get" method (the "const" specifier was missing).	9 years ago

mbarann	b48b2d43b0	MSMF expects a bottom-up video frame, so the buffer pointer must point to the end of the data and the stride needs to be negative	9 years ago

Marian Zajko	2998248dd3	Removed whitespaces reported by buildbot.	9 years ago

Pavel Rojtberg	955f489621	make CV_CAP_PROP_FORMAT consider the current channel count	9 years ago
Pavel Rojtberg	05f52b697f	replace uyvy_to_rgb24 by tested and conformant cvtColor	9 years ago
Pavel Rojtberg	ad68b79630	replace yuv420p_to_rgb24 by tested and conformant cvtColor Conversion was not ITU 601 conformant. Also add YVU420 format to allowed zero copy access.	9 years ago
Pavel Rojtberg	8527d895bb	replace rgb24_to_rgb24 by tested cvtColor internally using ipp this conversion is now roughly 2x faster. also add RGB/ BGR formats to allowed zero copy access.	9 years ago
Pavel Rojtberg	f50817120e	v4l: remove needless CvCaptureCAM_V4L_CPP wrapper possible source of memory leaks and unneeded complexity	9 years ago
Pavel Rojtberg	93d6e800b6	v4l: Fixed memory leaks and inconsistent status return values by updating to c++ coding conventions - const correctness - use bool as return value - use explicit initialization instead of CLEAR macro/ memset - use cv namespace	9 years ago
Pavel Rojtberg	a581ddd896	remove support of Video4Linux1 API the last kernel that allowed compiling this code was 2.6.37 which was released almost 5 Years ago. So probably it does not get much testing any more. Furthermore even back then one was better off using the V4L2 API. The only change touching currently used code is the removal of the global V4L2_SUPPORT variable.	9 years ago
Marian Zajko	691fb1ffae	XIMEA adapter update - replaced m3api/m3apiX64 binaries with latest xiapi32/xiapi64 to support latest camera models - added new parameter definitions to videoio_c.h and SetProperty/GetProperty calls - added acquisition resetting for specific parmateters in SetProperty call - added new error return value evaluators	9 years ago
grundman	f609ddba05	Fix incorrect FPS value returned by cap.get(CV_CAP_PROP_FPS) Current implementation returns NaN for some configs of FFMPEG, call default get_fps() instead (as also used by PROP_POS_MSEC)	9 years ago
Anton V. Shokurov	b9b40a73ba	Exposure and autofocus properties fixed/added. Exposure can now be manually controlled (implemented only in libv4l). Will work only with a kernel version >= 4.5. Autofocus can be enabled/disabled.	9 years ago
Pierre Letessier	e6615c5825	Changed CV_FFMPEG_CAP_PROP_SAR_* values	9 years ago
Pierre Letessier	baa21484a1	Added CV_CAP_PROP_SAR properties to videoio module	9 years ago
Pavel Rojtberg	eac5cab5cb	cap_v4l: implement PROP_CONVERT_RGB allows disabling automatic conversion to RGB for certain formats. If conversion is disabled the returned image just points to the underlying buffer, so no memcpy is performed. Note that we do not check image size in retrieve frame any more as it can not possibly while the device is streaming. Furthermore this code was disabled altogether by the wrong ifdef in the previous commit.	9 years ago
Pavel Rojtberg	5e62e71b13	fix wrong ifdef bracketing in the case of HAVE_CAMV4L2 && !HAVE_CAMV4L there was no body for the if statement.	9 years ago
Pavel Rojtberg	838947bb8e	replace custom yuyv_to_rgb24 implementation by cvtColor	9 years ago
Pavel Rojtberg	80747088e3	avoid needless copies during mjpeg decoding	9 years ago
Pavel Rojtberg	56dd7eda0d	remove additional V4L2 pixelformat defines they are upstream since at least linux 2.6.8 (10 Years) http://lxr.oss.org.cn/ident?v=2.6.8&i=V4L2_PIX_FMT_SBGGR8	9 years ago
Pavel Rojtberg	588eba3b37	simplify autosetup_capture_mode_v4l2 by using a for loop	9 years ago
Pavel Rojtberg	5525cc4d09	implement CAP_PROP_MODE, CAP_PROP_FOURCC and CAP_PROP_FORMAT do not use a custom enum instead of the V4L2 fourcc defines for palette. This way we can easily implement CAP_PROP_FOURCC and CAP_PROP_MODE.	9 years ago
Pavel Rojtberg	c0fe522c9d	allow changing FPS and Image Size using V4L2 use logic similar to cap_libv4l: replace icvSetVideoSize by v4l2_reset as it was not used for V4L1, the actual frame format is negotiated in try_palette_v4l2 and the stream has to restarted anyway.	9 years ago
Pavel Rojtberg	18034a5138	allow icvGetPropertyCAM_V4L to return zero now icvGetPropertyCAM_V4L behaves the same as in cap_libv4l. This also fixes passing boolean values.	9 years ago
Pavel Rojtberg	f7981a8ae8	support setting focus and autofocus with V4L2 also refactor property range handling and opencv property to V4L2 translation.	9 years ago
Alexander Stohr	7e3d7677ae	not only print file-not-found as a warning but also print the name of the problematic file and the uri used for the open attempt	9 years ago
Sergiu Dotenco	9da4fe4b02	videoio: fixed segmentation fault at frame size change	9 years ago
Alexander Alekhin	4760d32937	ffmpeg: fix invalid NULL pointer access Catched on Ubuntu 12.04 with FFMPEG: codec: YES (ver 53.35.0) format: YES (ver 53.21.1) util: YES (ver 51.22.3) swscale: YES (ver 2.1.0) resample: NO gentoo-style: YES	9 years ago
Pavel Rojtberg	345cd1242f	do not leak GstMapInfo it is new'ed but never deleted. However it does not need to be global or heap allocated in the first place.	9 years ago
Alexander Alekhin	50a0a167f0	fix ffmpeg frame creation (fix #5439 )	9 years ago
Dikay900	55df326589	PR #4003	9 years ago
jisli	f88e9a748a	update ffmpeg support Migration have been done for these ffmpeg/libav changes: 2013-12-11 - 29c83d2 / b9fb59d,409a143 / 9431356,44967ab / d7b3ee9 - lavc 55.45.101 / 55.28.1 - avcodec.h av_frame_alloc(), av_frame_unref() and av_frame_free() now can and should be used instead of avcodec_alloc_frame(), avcodec_get_frame_defaults() and avcodec_free_frame() respectively. The latter three functions are deprecated. 2012-10-08 - ae77266 / 78071a1 - lavu 51.74.100 / 51.42.0 - pixfmt.h Rename PixelFormat to AVPixelFormat and all PIX_FMT_* to AV_PIX_FMT_*. To provide backwards compatibility, PixelFormat is now #defined as AVPixelFormat. Note that this can break user code that includes pixfmt.h and uses the 'PixelFormat' identifier. Such code should either #undef PixelFormat or stop using the PixelFormat name.	9 years ago
Maksim Shabunin	771af4f32d	Some changes to support mingw-w64 - IPP is disabled by default when compiler is mingw (couldn't make it work) - fixed some warnings - fixed some `__GNUC__` version checks (for correctness and convenience) - removed UTF-8 BOM from hough.cpp (fixes #5253)	9 years ago
Alexander Duda	fbcf5f0918	cvCreateCameraCapture: fix using preffered interface The provided interface id must be removed from the index. Otherwise, the underlying implementations are using a wrong camera id. Example: VideoCapture(800) fails because PvAPI tries to open a camera on position 800	9 years ago
Bruno Goncalves	894c2468df	fix build error when both OpenNI and OpenNI2 are supported (issue 4918)	9 years ago
Oliver Lumby	2de3a24f46	fix CvVideoCamera defaultfps	10 years ago
Anton V. Shokurov	4691d98e19	Adds support for property CV_CAP_PROP_FOCUS in functions cvSetCaptureProperty and cvGetCaptureProperty. In compliance with the Windows (DirectDraw) version autofocus is disabled when either of the abovementioned functions is called.	10 years ago
ultrafro	ed574171bb	Fixed polarity of ImageRegistration mode in setDepthGeneratorProperty function of CvCapture_OpenNI2 class	10 years ago
Pavel Rojtberg	b1842a4b89	use simplified API selection logic in cvCreateCameraCapture as well	10 years ago
Pavel Rojtberg	2909e07cb2	deny any other interfaces if someone is specified as preference it provides more expectable results to end-users. based on feedback by Alexander Alekhin	10 years ago
Pavel Rojtberg	41d8c4d879	allow specifying apiPreference in VideoCapture when opening a file. Add a separate function instead of an overload not to change the ABI. rename VideoCapture paramter 'device' to 'index' in CPP to reflect that it allows specifying the API. update comments to explain how to specify the API.	10 years ago
