Abstract: An image prediction method and device are disclosed. The method includes: obtaining a first reference unit of an image unit, where respective predicted images are obtained for the image unit and the first reference unit by using a same affine model; obtaining motion information of basic motion compensation units at two or more preset positions of the first reference unit; and obtaining motion information of a basic motion compensation unit of the image unit according to the motion information. In this way, motion information of the first reference unit using a same affine motion prediction model is reused, and a more accurate motion vector of a current image unit is obtained, improving prediction accuracy and maintaining encoding and decoding complexity, thereby improving encoding and decoding performance.

Abstract: This application provides a service sharing method and system, and an electronic device. The method includes: A first device may display a chat interface with a first contact, where the chat interface includes an input box for a chat message. If it is detected that a user inputs a preset symbol into the input box, the first device displays a first device list. If it is detected that the user selects a second device from the first device list, the first device displays a service list provided by the second device, where the service list includes one or more services provided by the second device. If it is detected that the user selects a first service from the service list, the first device sends a first chat message in the chat interface, where the first chat message includes first service content corresponding to the first service selected by the user.

Abstract: A detection device runs a first sample file in a first virtual operating environment, when the first sample file sends a first Hypertext Transfer Protocol (HTTP) request to a server, the detection device obtains an identifier of the first sample file and a first data flow identifier correspondingly from the first HTTP request. The detection device obtains a second data flow identifier and a second sample file carried in subsequently transmitted data flow. If the second data flow identifier is the same as the first data flow identifier in the correspondence, the detection device determines that the second sample file is a subsample file of the first sample file, detects the second sample file to obtain a detection result of the second sample file, and determines, based on the detection result of the second sample file, that the first sample file is a malicious file.
