trdrop

The main use of this software is to estimate the "real" framerate of an uncompressed video.

Usually, a dedicated capture card is employed to capture the video stream with a fixed framerate of a console. To estimate the real framerate of the console, we check for differences on a frame-by-frame basis and count the different frames. This results in the "real" framerate.

The same is done with the frametime, as we count the amount of time a single frame is shown.

We also try to detect frametears and incorporate them into the framerate and frametime calculation.

Hence the name tr (short for tear) and a framerate drop.
