@LBerger so the above code is right if we consider the explanation in that link, no need to get milliseconds from the fr

okey @LBerger

@berak can this be done ?

How to ignore the first and the last 10% of the videoCaption ? Hello, I've a video which starts by black stream and end

hello,

I've written this code which opens tree images and push them with some infos inside vector<ColletorMat> setFrames then I save this vector of Mat within a binary file. so as to load it later and open these images again. however, I didn't get the aim

any will be appreciated

hi,

I've issue with multi thread and CMAKE

I've written this code using multi-thread it works fine in windows, however, when I tried to run it in CentOS using CMAKE it works in a sequential manner which is weird

project structure :
