Abstract: A floating window processing method and apparatus is disclosed. The method includes: displaying a floating window in a target display area of a display screen; obtaining an operation signal that works on the floating window; determining a form variation parameter of the floating window according to the operation signal; and dynamically regulating a display form of the floating window, the display form including a display location and/or size. With this disclosure, a problem that a floating window is displayed in a fixed location on a screen, causing great inconvenience for watching other content that is displayed out of the floating window is resolved, a moving function and a zoom function of the floating window are extended. Therefore, it is convenient for the user to watch the other content that is displayed out of the floating window.

Abstract: System and methods related to video information distribution are provided. The system may obtain a video source address. The system may receive a video segment of a video stream from a remote server configured with the video source address. The system may parse the video segment for header information. The system may determine that a video corresponding to the video source address is playable on a remote device in response to the header information being included in the video segment. The system may store the video source address in a database. The database may include a plurality video addresses corresponding to respective videos that are playable on the remote device.

Abstract: A web page display method and apparatus, a mobile terminal, and a storage medium are provided. The method includes: parsing source code of a specified web page requested to display, to obtain Document Object Model (DOM) tree information, JavaScript code, and at least two pieces of style rule information; determining a current display mode; and selecting style rule information corresponding to the current display mode from the at least two pieces of style rule information. The method also includes: executing the JavaScript code, to obtain a JavaScript execution result; and displaying the specified web page according to the DOM tree information, the JavaScript execution result, and the style rule information corresponding to the current display mode.

Abstract: This application discloses a video decoding method for a mobile terminal. The method includes receiving a video file from a server; based on a hardware-decoding model whitelist and a hardware-decoding operating-system blacklist, obtained from a server, and locally obtained type information of the mobile terminal, determining whether a decoding method of the video file is hardware decoding or software decoding; and decoding the video file by using the determined decoding method and playing back the decoded video file, wherein the hardware-decoding model whitelist includes model information of mobile terminals that can perform hardware decoding on the video file, and the hardware-decoding operating-system blacklist includes model information of mobile terminals that do not support hardware decoding on the video file and version numbers of operating systems of the mobile terminals.
