+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
