Milian Wolff b5e4f06e9f Fix linking on recent Qt for iOS 
The qtmn hack is not required anymore.
 2017-01-10 13:17:54 +01:00
Milian Wolff 0e10d8aeca Add simple FPS counter to QZXingLive example 2017-01-10 13:17:54 +01:00
Milian Wolff 69e05c1ff1 Add support for NV12 video frames 
This was encountered on a recent Android device.
 2017-01-10 13:17:54 +01:00
Milian Wolff 75b1a0d355 Further optimize QZXingFilterRunnable::processVideoFrameProbed 
Do not call detaching QByteArray::data, use constData instead.
Also hoist some constants out of the inner conversion loops and make
more variables const.
 2017-01-10 13:17:54 +01:00
Milian Wolff 3eb5b0b869 Cleanup debug code, save at most 100 images. 2017-01-10 13:17:54 +01:00
Milian Wolff bc2badb5b5 Optimize: reduce memory allocations, convert directly to grayscale 
This dramatically improves the performance of the QZXingFilter.
 2017-01-10 13:17:54 +01:00
Milian Wolff d112bf4186 Don't try harder by default in the QZXingLive example 2017-01-10 13:17:54 +01:00
Milian Wolff 7937cb84b5 Only try to mirror images when tryHarder is set to true 
Additionally, this is only done until a match is found, instead of
always applying mirroring for the 2nd, 3rd and 4th frames.

Milian Wolff cafad4a9c0 Add captureRect functionality 
This allows one to only detect within a certain unscaled region
of the input frame. The reduction of pixels scanned leads to
a significant performance win, and the removal of the scaling
improves the quality of the checked image, thereby leading to
higher detection rates.
 2017-01-10 13:17:54 +01:00
Milian Wolff a7103d5cac Expand QZXingFilter example code 
- allow autofocus and manual focus
- count number of tags matched
- allow configuring the barcode scanner from QML
 2017-01-10 13:17:54 +01:00
Milian Wolff eba661a424 Make QZXing's tryHarder, charSet and foundedFormat accessible from QML 2017-01-10 13:17:54 +01:00
Milian Wolff 4c22c65b5e Constify data and put it into the .rodata section 2017-01-10 13:17:54 +01:00
Milian Wolff bb903ca27e Enable all decoders by default 
Otherwise this leads to access of uninitialized, when one forgets
to set a custom list of decoders.

Nikolaos Ftylitakis bd96c910e9 Merge pull request #6 from sergey-platonov/isnan-fix 
zxing::isnan for non-msvc compilers was implemented with c99 function,
which is still not fully supported by some compilers (e.g., GCC).
Added an implementation for compilers without c++11 or c99 support. And wrapped
all related code in #if.

favoritas37 d5e5c895d8 For backward compatibility, after merging pull request #3, the original tagFoundAdvanced signal has been reimplemented. Also added try catch clause around the new singal since in a lot of cases it fails to detect the decoded barcode's rectangle. To be improved. 2016-09-27 02:06:54 +03:00
