Abstract: A cross-platform video playing method, playing device and playing system is presented. The method includes the steps of receiving a shared video sent by a first terminal; detecting whether a video format of the shared video is consistent with a video format which is supported by a default video player on a second terminal; in case if it is detected that the video format of the shared video is inconsistent with the video format which is supported by the default video player on the second terminal, converting the shared video into a video media file that can be played by the default video player on the second terminal; and transmitting the video media file to the second terminal, such that the received video media file can be played directly by the default video player without having to perform video format conversion or installing a video player on the second terminal.

Abstract: A method, apparatus, server and system for adapting a client to a hardware environment is presented. A server obtains hardware environment information of a client. The hardware environment information includes one or both of hardware and software configuration information of the device terminal which support operations of the client, wherein the client includes an application having codes executable by the device terminal to perform at least one hardware function in the device terminal. The server sends matched configuration parameters according to the hardware environment information to the client. The client combines codes of the configuration parameters with codes of default dynamically configurable information to generate a correction result, which correction result is utilized by the client to perform the at least one hardware function in the device terminal.
