• Mark the starting point and the ending point for play.
• Set an infinite loop or a repeat count.
• Get content information such as author, copyright, etc.

• Play streaming music and video from memory.
• Grab the current frame from the screen.
• Control the playback speed (2x, 3x, 4x, 1/2x, 1/3x, 1/4x)
