Subject: [PATCH] modules/video_filter/opencv_example.cpp: fix build with
|
opencv 3.4.9
|
|
Use cvScalar instead of CV_RGB to avoid the following build failure with
|
opencv 3.4.9:
|
|
In file included from /home/naourr/work/instance-2/output-1/host/x86_64-buildroot-linux-uclibc/sysroot/usr/include/opencv2/imgproc/imgproc.hpp:48,
|
from video_filter/opencv_example.cpp:46:
|
video_filter/opencv_example.cpp: In function 'picture_t* Filter(filter_t*, picture_t*)':
|
video_filter/opencv_example.cpp:200:46: error: could not convert 'cv::Scalar_<double>((double)0, (double)0, (double)0, (double)0)' from 'cv::Scalar' {aka 'cv::Scalar_<double>'} to 'CvScalar'
|
cvRectangle( p_img[0], pt1, pt2, CV_RGB(0,0,0), 3, 8, 0 );
|
^~~~~~
|
|
Indeed, CV_RGB is defined as cv::Scalar instead of cvScalar since
|
version 3.4.2 and
