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.

Browser-based frame extraction method and system

The present disclosure describes techniques of presenting audio/video (AV) files. The disclosed techniques include displaying a first interface, wherein the first interface comprises a list of a plurality of AV files and an editing area; generating a plot graph based at least in part on an input by a first user via the first interface, wherein the plot graph has a directed structure, and the at least one first type of AV file and the at least one second type of AV file are associated with different nodes of the plot graph; playing a first type of AV file; detecting that a preset instruction is received in response to determining that a playing progress of the first type of AV file reaches a first predetermined position; and playing another first type of AV file or a second type of AV file based on the preset instruction.
