zzPlayer is a straightforward video player that supports all the standard formats.
zzPlayer will open and play any file as long as the required codecs are present on your system. It uses the OpenCV external library to access the frames of a video file. The display of the video frame is provided through OpenGL; as the frame is read from the file, it is loaded directly into your graphics card for display.
zzPlayer is sizable via presets or by dragging the margins to obtain the desired size; you can also get data about the video like size, length, frames, FPS, and codec type if needed.
If you need to play a video and don't want to mess around with an overly complex player, give zzPlayer a try.
