Abstract
A method for dividing a group of pictures (GOP) based on scene switching in encoding a video. The method includes determining whether a scene switching frame is present in a current GOP of received video data. It is then determined whether a last video frame of the current GOP is the scene switching frame. A first scene switching frame of the current GOP is also determined as a target scene switching frame and this target scene switching frame is acquired by traversing the scene switching frames from back to front. The video frame previous to the target scene switching frame is set as the last video frame of the current GOP. A next GOP is determined to include the number of video frames that follow the target scene switching frame and include the target scene switching frame.
