After recording a slo-motion video (the activeFormat, the activeVideoMinFrameDuration and the activeVideoMaxFrameDuration properties on the AVCaptureDevice object have been changed to the proper values), the slo-motion effect is missing when the video is played directly after the didFinishRecordingToOutputFileAt
method has been called.
I tried to reduce the rate of the player and the video slows down but it's not the same as if I saved the video into the Library and then I play it.
Any idea on how I can achieve this ?
