Hello guys, i believe this question isn't that hard but for some reason i cant seem to find any answers on the internet. Maybe i am not doing some good research.

I am having a counter(integer) on my program which is the one named t. It changes from time to time according to some camera interactions i am doing. I just want this to be shown in the video result, the one named pProcessedFrame.

Command cvPutText that i am including here, doesnt work for me because it can only show specific text. I want it to change from time to time like i mentioned before.

Any other command i am not aware of?
