Abstract: Embodiments of the present disclosure disclose a method and apparatus for processing a video frame. A specific embodiment of the method includes: receiving a video frame set; selecting a video frame from the video frame set, and performing following processing: creating a pixel buffer object newly; reading pixel data of the selected video frame from a frame buffer corresponding to a central processing unit, and writing the read pixel data into the newly created pixel buffer object; storing the written pixel buffer object into a pixel buffer object queue; determining whether an unselected video frame is present in the video frame set; and storing the video frame set in response to determining no unselected video frame being present in the video frame set.

Abstract: Embodiments of the present disclosure relate to a method and apparatus for processing a video frame. The method may include: acquiring a sequence of video frames of a video; ascertaining, in the sequence of the video frames, a previous frame, and ascertaining, in the sequence of the video frames, a subsequent frame corresponding to the ascertained previous frame based on acquired number of frames from the previous frame to the subsequent frame. An update step is performed as follows: acquiring object regions detected respectively in the ascertained previous frame and the ascertained subsequent frame, and confidence levels of the object regions; fusing a confidence level of a first object region and a confidence level of a second object region, and updating the confidence level of the second object region based on the fusion result; and updating the ascertained previous frame and the ascertained subsequent frame.

Abstract: Embodiments of the present disclosure relate to a method and apparatus for processing a video. The method may include: acquiring object regions obtained by performing object detection on a target video frame, a type of an object in each of the object regions being a preset type; determining, for an object region in the acquired object regions, in response to determining that the object region satisfies a preset condition, that the object region is a non-ROI; using an object region other than the non-ROI in the object regions of the target video frame as a ROI; and acquiring a quantization parameter change corresponding to each ROI, and encoding the target video frame based on the quantization parameter change.

Abstract: The present application discloses a virtual machine migration method and apparatus. A specific implementation of the method includes: receiving a migration request for migrating a virtual machine, wherein to-be-migrated data of the virtual machine comprises local data locally stored and shared data accessible by the virtual machine at a plurality of locations; determining migration operations respectively corresponding to the local data and the shared data in response to the migration request; and executing the migration operations corresponding to the local data and the shared data, to complete migration of the virtual machine. This implementation achieves the migration of a virtual machine with a hybrid storage mode, that is, a storage mode in which the data to be migrated includes both local data and shared data.
