Looks like it is an issue using opencv 4.x I found that one of the forks has 4.x implemented.. https://github.com/thinkpiece/Yolo_mark

I got same issue and got fixed by just removing CV_ from CV_FILLED and CV_CAP_PROP_FPS from main.cpp. opencv 4.0.0 Linux Mint 19.1

@ido-ran @RRMoelker @vinjn @lovexytoo I fixed it. Now Yolo_mark supports OpenCV 3.x and 4.x

I had this issue ‘FILLED’ was not declared in this scope error: ‘CAP_PROP_FPS’ was not declared in this scope

I solved it just by adding CV_ before ‘CAP_PROP_FPS’ and 'FILLED'

@AzimovS

• What OS and OpenCV version do you use?

• Do you use the latest version of Yolo_mark?

@AlexeyAB Sorry, forgot to mention. Ubuntu 16.04 and OpenCV version is 3.4.5 I downloaded Yolo_mark version a few minutes ago, so I think it is the latest version
