Abstract

The invention provides a video definition switching method and a video player. The method comprises the following steps: loading a first fragment file of a first definition video from a preset second level buffer area into a video stream buffer area to be played; receiving a definition switching instruction; obtaining a configuration file of a second definition video from a video server according to the instruction, wherein the configuration file comprises time information and address information of each fragment file in the second definition video; determining a second fragment file conforming to a smooth switching condition in the second definition video corresponding to the first fragment file; loading the fragment files behind the second fragment file in the second definition video into the second level buffer area in sequence; and loading the fragment files into the video stream buffer area to start to play the second definition video after the first fragment file is played. The video definition switching method provided by the invention is used for realizing the seamless switch of different video definitions.
