Disclosed in embodiments of the present disclosure are a method and an apparatus used for image display. A specific embodiment of the present method comprises: determining a selected time point of a user performing adjustment of playback progress of a target video, the target video comprising a key frame set; determining a target key frame in the key frame set, a difference between a time point corresponding to the target key frame and the selected time point meeting a first pre-determined condition; on the basis of the target key frame, performing decoding of a video frame corresponding to the selected time point, obtaining a decoded video frame; displaying the decoded video frame in a first target display region. The present embodiment increases flexibility of video frame display, and helps increase user positioning and video frame processing effectiveness.

An image processing device includes a multimedia intellectual property (IP) block which processes image data including a first component and a second component; a memory; and a frame buffer compressor (FBC) which compresses the image data to generate compressed data and stores the compressed data in the memory. The frame buffer compressor includes a logic circuit which controls a compression sequence of the first component and the second component of the image data.

A buffer device stores, in relation to a first area and a second area, which are partial areas respectively located on an identical line of an encoding target frame, and a third area, which is a partial area on the line below the identical line, reference image data for each search range of a reference frame that is referred to during motion search processing executed in order of the first area, the second area, and the third area, the buffer device including a memory for storing the reference image data, and a buffer control unit which, when the motion search processing is executed on the second area, executes control so that among the reference image data included in a first search range that is referred to during the motion search processing of the first area, the reference image data included in a third search range that is referred to during the motion search processing of the third area are left in the memory without being deleted.

An image capture device for recording HDR (high dynamic range) image data obtained through image capture performs control so as to, when encoding HDR image data obtained by capturing an image with an image sensor, divide part of the HDR image data corresponding to a coding area to be encoded into a plurality of divided HDR image data, encode each of the plurality of divided HDR image data by using encoding means, and record the plurality of divided HDR image data that are encoded on a recording medium in a predetermined recording format.

In various embodiments, an encoding optimization application encodes a source video sequence. The encoding optimization application partitions a source video sequence associated with a media title into multiple subsequences that include a first subsequence and a second subsequence. The encoding optimization application then generates a first encoded subsequence based on the first subsequence and a first resolution. The encoding optimization application generates a second encoded subsequence based on the second subsequence and a second resolution. Notably, the second resolution is higher than the first resolution. The encoding optimization application then aggregates the first encoded subsequence and the second encoded subsequence to generate an encoded video sequence. At least a portion of the encoded video sequence is subsequently streamed to an endpoint device during a playback of the media title.

The present disclosure provides a split-screen playback method, apparatus and device for lock screen video and a storage medium. The method includes: monitoring whether a screen enters a screen-locked state; upon monitoring that the screen enters a screen-locked state, obtaining at least two video files; playing the video files on different display areas of the screen, respectively; wherein a number of the display areas is consistent with a number of the video files. The present disclosure can implement split-screen playback for lock screen video without changing hardware of a terminal, thereby effectively improving the playback efficiency of the video, facilitating popularization and application, and providing good user experience.

The present disclosure provides a method and apparatus of editing a multimedia file, an electronic device, and a storage medium. The method includes: acquiring a multimedia file and an operation information contained in each editing track of a plurality of editing tracks, wherein the operation information is acquired to edit the multimedia file; detecting a multimedia file frame contained in the each editing track at a current time in a case of editing the multimedia file in a chronological order; editing the multimedia file frame contained in the each editing track at the current time by using the operation information associated with the multimedia file frame, so as to obtain an edited file frame contained in the each editing track at the current time; and performing an encoding synthesis on the edited file frame contained in the each editing track at the current time.

A system and method disposed to enable encoding, decoding and manipulation of digital video with substantially less processing load than would otherwise required. In particular, one disclosed method is directed to generating a compressed video data structure that is selectively decodable to a plurality of resolutions including the full resolution of the uncompressed stream. The desired number of data components and the content of the data components that make up the compressed video data, which determine the available video resolutions, are variable based upon the processing carried out and the resources available to decode and process the data components. During decoding, efficiency is substantially improved because only the data components necessary to generate a desired resolution are decoded. In variations, both temporal and spatial decoding are utilized to reduce frame rates, and hence, further reduce processor load. The system and method are particularly useful for real-time video editing applications.
