I am an iOS developer who should make an app to play video with various speed.
I think there is no API to change playback speed on MPMoviePlayerController.

And I couldn’t find any solutions.

Can you please tell me how to implement it?
or Can you please tell me any Framework/library(SDK) that support above functions for iOS?

    There actually is such property.

    MPMoviePlayerController adheres to the MPMediaPlayback protocol

    See 

    currentPlaybackRate

    The current playback rate for the player. (required)

    @property(nonatomic) float currentPlaybackRate

    Discussion

    This value represents a multiplier for the default playback rate of
    the current item. A value of 0.0 indicates that playback is stopped
    while a value of 1.0 indicates that playback is occurring at normal
    speed. Positive values indicate forward playback while negative values
    indicate reverse playback.

    Setting the value of this property changes the playback rate
    accordingly.
