Abstract: This application discloses a video frame playing method performed by a computer device. According to an embodiment of this application, the computer device transmits network delay information to a cloud game server. The cloud game server then generates a plurality of first video frames based on the network delay information for rendering a target virtual scene at the computer device. After acquiring the plurality of first video frames, the computer device adjusts a resolution of the first video frames to obtain corresponding second video frames when resolutions of the plurality of first video frames meet resolution adjustment conditions, resolutions of the second video frames being higher than those of corresponding first video frames. Finally, the computer device plays a plurality of the second video frames.

Abstract: A method includes encoding a first picture frame in a video clip as a video key frame, and encoding a plurality of picture frames after the first picture frame according to an encoding order. For a current picture frame, if it is determined that a network status of a receiving end satisfies transmitting and receiving conditions, the current picture frame is encoded based on a corresponding frame type of the current picture frame in a first encoding structure, and if it is determined that the network status does not satisfy the transmitting and receiving conditions, the current picture frame is encoded based on a corresponding frame type of the current picture frame in a second encoding structure. A quantity of bidirectional predicted frames in the second encoding structure is smaller than that in the first encoding structure.

Abstract: Embodiments of the present disclosure provide a data buffering method. In the method, a network device obtains multimedia data and network characteristic information of a communications network. The communications network includes a first communications network or a second communications network, the first communications network is configured to transmit the multimedia data to the network device, and the second communications network is configured to transmit the multimedia data to a terminal device. A target data volume corresponding to the terminal device is determined at least based on the network characteristic information of the first communications network and/or the second communications network. First buffered data representing the multimedia data is determined based on the obtained multimedia data and has the target data volume. The first buffered data is sent to the terminal device by using the second communications network. A data volume of the first buffered data matches the network characteristic information.
