• Ability to play local, remote audio, video files
• Bring your own Playback Control Panel (pause, play, play progress, whether you want Fullscreen)

4> Mpmovieplayerviewcontroller

• Ability to play local, remote audio, video files

• The playback interface is full screen by default
• If the playback function is relatively simple, simply play the remote, local video files, it is recommended to use this
