Hi all, I want to play four fullhd videos and i'm using a sample and grab frame in each iterate in loop and show it four times in a concatenate way in just one imshow. i have a problem with speed. it is faster than its real. how can i play it in exact frame rate that it has? i am using C++. if there is a better solution in C# please let me know it. i have found some but there is error in opening file in all of them. Thank you
