OpenCV video playback too fast

[Ruth]

I'm running the samples and the video playback is about twice as it should be. Could it be a problem with ffmpeg/x264?

Anyone know what's up?

Sorry I meant to say above the video is twice as *fast* as it should be.

What amount of time are you using in Wait()? When you are simply reading a video file, it will do it as fast as possible without regard for the fps of the video. So if you use your standard Wait(30) it will probably play back at around 30fps taking into account overhead from reading the video file. You should read the fps of your input video and then adjust your wait duration accordingly.
