Abstract: The present disclosure relates to a method, a device and a system for computer game difficulty assessment. The method comprises: recording game data by a data collector in a process of simulating game playing by operating a computer game through an API (Application Programming Interface) of the computer game using an agent algorithm; measuring a goal attainment difficulty of the computer game at this timing according to goal completion degrees of a plurality of goals corresponding to all attempts at each decision-making timing in the recorded game data; measuring a strategy space-related difficulty of the computer game at this timing according to goal completion degrees of a plurality of goals corresponding to all actions at each decision-making timing in the recorded game data; assessing difficulty of the computer game based on a goal attainment difficulty and a strategy space-related difficulty at each timing.

Abstract: The present disclosure describes techniques of processing information flow and synchronously displaying image frames, mask frames and comment information. According to the present disclosure, a system processes a first information stream uploaded by a stream pushing terminal to obtain a frame image and mask frame data, the mask frame data corresponding to the frame image and identifying a timestamp offset indicative of a time difference between the mask frame data and a playing timestamp of the frame image. The system synthesizes the frame image and the mask frame data to generate a second information stream; and output the second information stream to a client for synchronously displaying the image frame, a corresponding mask frame, and the comment information.

Abstract: 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.

Abstract: Techniques for displaying comments relative to a video frame are described herein. The disclosed techniques include receiving a frame of a video; receiving bullet screen data comprising a plurality of comments associated with the frame; receiving a mask frame data segment corresponding to the frame; determining a mask area based on the mask frame data segment, wherein the mask area corresponds to a main area of the frame; and displaying the plurality of comments relative to the frame in areas other than the mask area.
