Abstract
Embodiments of the present application provide a browser-based frame extraction method. The method includes: monitoring a target operation of a user on a target page of a browser; obtaining a local video file associated with the target operation; and extracting a plurality of target frames from the local video file using a WebAssembly video parser in the browser. This disclosure enables a browser to independently complete operations such as frame extraction on videos in various encoding formats so as to reduce server load.
