Remove obsolete FFMPEG versions support
* refactor: removed obsolete FFMPEG version support
- Oldest available version via official FFMPEG repository mirror has tag v.0.5
LIBAVFORMAT version for this tag is 52.31.0
* refactor: prefer std::min function to MIN macro
* refactor: use appropriate macro instead of manual version calculation
* refactor: remove macros for versions prior 0.5.15 release
* refactor: remove libavcodec macros for versions < 54.35.1 (default to Ubuntu 14.04)
* refactor: remove libavformat macro for versions < 54.20.4 (default ubuntu 14.04)
* refactor: remove libavutil macro for versions < 52.3.0 (default ubuntu 14.04)
* refactor: remove missed macros for libavcodec and libavformat
* refactor: remove unused _opencv_ffmpeg_free function
* build: add FFMPEG libraries versions checks
- Add verbose message about what FFMPEG libraries are missing.
- Add minimal versions check set to libav 9.20 release (default ubuntu 14.04) and FFMPEG 1.1.16 release.
If the check is failed CMake produces user-friendly message instead of build error.
* fix: libavcodec version guard for AVDISCARD_NONINTRA
* fix: libav check of libavcodec version guard for AVDISCARD_NONINTRA
* fix: version check for AV_CODEC_FLAG_GLOBAL_HEADER
* fix: missing FFMPEG libraries output
- Added test for automated rotation for MP4 videos with metadata
- Fix 180 degrees rotation bug
- Moved rotation logic to cv::VideoCapture implementation for FFmpeg and restore binary compatibility with FFmpeg wrapper.
- Add VideoCapture camera orientation property for mp4 videos with camera orientation meta.
- Add auto rotation for 90, 180, 270 degrees using cv::rotate

* feature: Extend VideoWriter to accept vector of parameters
- Add additional constructor and `open` method for `VideoWriter`
those accept a vector of parameters
- Move actual implementation of the `VideoWriter::open` to general method
which accepts vector of parameters
- Propagate parsed parameters map up to actual video backend construction
* fix: Change VideoWriter constructor description to suppress doc warning
* refactor: Rollback newlines changes
* feature: Changed VideoWriter parameters workflow
* feature: Log unused parameters in VideoWriter open
* doc: Fix VideoWriter `isColor` parameter description
* fix: int to bool VC++ conversion warning
* doc: Remove information about `isColor` flag usage.
I believe you are using the wrong version of open() on line 28 - adding deviceID + appId together. It's better to use the new version of .open() taking two integers as parameter.
* feature: Add video capture bitrate read-only property for FFMPEG backend
* test: For WIN32 property should be either expected or 0.
Added `IsOneOf` helper function, enabled only for _WIN32.
- Added `explicit` to `VideoCapture` constructors with 2
arguments, 1 of them has default value
- Applied library code style
- Introduced 2 debug macros to improve readability of the code
* Fix infinite loop when trying to change state of the busy camera
- Add finite number of attempts in tryIoctl functions
10 by default.
* Introduced new flag for ioctl call to handle EBUSY
Add retrieve encoded frame to VideoCapture
* Add capacity to retrieve the encoded frame from a VideoCapture object.
* Correct raw codec and pixle format output from ffmpeg capture.
* Remove warnings from build.
* Added VideoCaptureRaw subclass.
* Include abstract base class VideoCaptureBase and rename new subclass VideoContainer as suggested by mshabunin.
* Remove using.
* Change base class name for compatibility with jave bindings generator.
* Move grab and retrieve and add override specifier
* Add setRaw and readRaw to IVideoCapture interface
-setRaw to disable video decoding and enable bitstream filters from mp4 to h254 and h265.
-readRaw to return the raw undecoded/filtered bitstream.
Add createRawCapture to initiate a backend with setRaw enabled.
Remove inheritance and use an independant VideoContainer subclass with IVideoCapture member.
* Address unused parameter warings.
Remove VideoContainer from python bindings as it no longer returns a Mat.
Use opencv type uchar instead of unsigned char.
Add missing destructor to VideoContainer class.
* Address build warnings and include all params in documentation.
* Include deprecated bitstream filtering API.
* Update codec_id query to work with older ffmpeg api's.
Change api version defines to be consistent - most recent api version first.
* Fix typo.
* Update test to work with naming of new files in the extra repo
* Investigate test failure
* Check bytes read by ffmpeg
* Removed mp4 video container test
* Applied suggested changes.
* videoio: rework API for extraction of RAW video streams
- FFmpeg only
* address review comments
Implement Camera Multiplexing API
* IdideoCapture + two wrong function
function waitAny
Add errors catcher
Stub for Python added.
Sifting warnings
One test added
Two tests for camera and Perf tests added
* Perf sync and async tests for waitAny() added, waitAnyInterior() deleted, getDeviceHandle() deleted
* Variable OPENCV_TEST_CAMERA_LIST added
* Without fps set
* ASSERT_FAILED for environment variable
* Perf tests is DISABLED_
* --Trailing whitespace
* Return false from cap.cpp deleted
* Two functions deleted from interface, +range for, +environment variable in test_camera
* Space deleted
* printf deleted, perror added
* CV_WRAP deleted, cv2 cleared from stubs
* -- space
* default timeout added
* @param changed
* place of waitAny changed
* --whitespace
* ++function description
* function description changed
* revert unused changes
* videoio: rework API for VideoCapture::waitAny()
If an aravis camera is software triggered, a trigger needs to be explicitly sent using `arv_camera_software_trigger`, otherwise the camera will not grab any frames.
* Fix the detection of XIMEA on Windows (when it has been installed by another user with administrative privileges, for example).
* Change the flow: we first try HKEY_CURRENT_USER key and, if empty, then try HKEY_LOCAL_MACHINE
* Remove unavoidable print of CV error
The return value covers whether the device exists.
This might be better hidden behind a debug flag, but I couldn't work out how to do that nicely.
* Use `CV_LOG_WARNING` macro to log rather than removing it entirely
