Abstract

A method for switching video resolution includes: confirming that a video sender and a video receiver have established a video communication connection, and obtaining an initial resolution of the video sender; confirming that bandwidth of the video communication connection and hardware of the video sender meet preset conditions, and switching the initial resolution of the video sender to a target resolution, in which the target resolution is higher than the initial resolution. After establishing video communication connections between terminals, when there are available bandwidth and hardware of the terminal using video communication, the resolution of terminal may be switched to provide a more clear video communication for terminal user, and guarantee smooth switching of resolution.
