Abstract
A method for adjusting video quality based on a network environment is provided. The method includes receiving a target frame serial number of a lost video frame from a terminal device, and using a time when the target frame serial number is received as a timestamp of the target frame serial number; determining a number of target frame serial numbers corresponding to timestamps within a predefined time period; decreasing a designated image quality parameter according to a predefined configuration when the number of target frame serial numbers is greater than a first threshold; and increasing the designated image quality parameter according to the predefined configuration when the number of target frame serial numbers is less than a second threshold. The first threshold is greater than the second threshold.
