Use correct integer types for arguments to TIFFGetField to avoid corruption
of values and failed loads of TIFF file when using cv::imread().
Added test where both big and little endian TIFF files are read using imread().
Fixed build of 3rdparty libtiff on big endian hosts.
Reduced memory required during decode_tile16384x16384 test by not converting
large grayscale test image to color image during read.
Also deleted miscellaneous remaining multimon cruft.
Deleted #include <winuser.h>, because <windows.h> includes it
already.
This should have a nice side effect of preventing us from
accidentally using any Windows API that's too new.
avformat_find_stream_info was introduced in Libav avformat 53.3,
but it was only merged to FFmpeg in avformat 53.6.
In Libav avformat 53.3-53.5 av_find_stream_info is not removed
(only deprecated), so this shouldn't break building with that.
Searching in directory names can yield confusing results; e.g. if
the input is "jpeg2000/image1.jp2", it will infer the pattern
"jpeg%04d/image1.jp2", which is likely not what the user intended.
If the user really desires for the variable part to be in the
directory name, it can always use an explicit pattern.
Our prebuilt FFmpeg Windows binaries don't have PNG support enabled
(because that requires zlib), so that makes a PNG image a bad choice
for this test.
When FFmpeg doesn't support PNG, VideoCapture falls back to the
"image sequence" implementation, which doesn't work for single images.
- crosses initializations in "cap_ximea.cpp" (which also contained some awfull "goto" instructions)
- the "CMAKE_CL_64" variable is not initialized when using mingw
PR#1039 modified to be able to merge on branch 2.4
Previously, VideoCapture::retrieve would return a Mat that referenced
the internal IplImage. Since the latter is rewritten every time a
frame is captured, it means that if the user captures two frames in a row,
the first frame would reference nothing. Similar if a user captures a frame,
then destroys the VideoCapture instance.
Note that the other branch of the if isn't affected, since flip allocates
a new Mat.
From commit dd74a851, to be exact. Now cap_ffmpeg.cpp should actually
build if HAVE_FFMPEG is true.
Also modified some gpu sources in a similar manner.
