MPMoviePlayerController .mp4 format not supported in iPhone device

hii, I am playing a video on iPhone in MPMoviePlayerController but it is not supporting .mp4 format it 开发者_JAVA百科is showing "This video format is not supported" while when playing video of format .mov it is playing easily,can u help me out of this.......

The quickest answer is that the video needs to be converted to a codec/resolution/bitrate that the iPhone OS supports. Handbrake, Xilisoft, and others have specific settings for iPhone/iPod. Use one of those, convert using the specific settings, and try again.
