Embodiments of the present disclosure disclose a video decoding control method and apparatus, an electronic device, and a storage medium. The method includes detecting, in response to detecting a plurality of application programs running in a split-screen mode, one or more application programs in a video playback state among the plurality of application programs; acquiring the one or more application programs detected in the video playback state to serve as one or more to-be-configured application programs; and providing a configuration to decode a video played by the one or more to-be-configured application programs in a manner of hard decoding.

A data processing system is disclosed, including one or more processors, a memory, and a plurality of instructions stored in the memory and executable by the one or more processors. The instructions may be executed to convert an input video file to a commonly used video format, and compare a resultant file size to a threshold size. In response to the file size being greater than the threshold size, the instructions may be executed to reduce a video bit rate of the input video file, and produce a Portable Document Format file that includes contents of an input Portable Document File and in which the input video file is embedded.

Provided are a video recording method and apparatus. The video recording method includes: in response to detecting a resume recording instruction, determining duration of a video coded by a video coder, and setting playback progress of an audio player to the duration, where the resume recording instruction is used for instructing to continue collecting video data and continue playing target audio data by using the audio player; starting the audio player, where the video coder is started before the audio player; in the case of playing the target audio data to the playback progress, in response to collecting the video data, transmitting the collected video data to the video coder so that the video coder codes the collected video data.

In various embodiments, an iterative encoding application encodes a source video sequence. The encoding optimization application generates a set of shot encode points based on a set of encoding points and a first shot sequence included in the source video sequence. Each shot encode point is associated with a different encoded shot sequence. The encoding optimization application performs convex hull operation(s) across the set of shot encode points to generate a first convex hull associated with the first shot sequence. Subsequently, the encoding optimization application generates encoded video sequences based on the first convex hull and a second convex hull associated with a second shot sequence included in the source video sequence. The encoding optimization application computes a new encoding point based on the encoded video sequences and a target value for a first video metric and then generates an optimized encoded video sequence based on the new encoding point.

In various embodiments, an encoding optimization application positions key frames within encoded video sequences based on shot changes. The encoding optimization application determines key frame location(s) based on shot change(s) included in a source video sequence associated with a media title. Each key frame location is associated with a different frame included in the source video sequence. For each of the key frame location(s), the encoding optimization application configures an encoding application to encode a frame of video content located at the key frame location as a key frame when performing encoding operations. Subsequently, the encoding optimization application causes the encoding application to perform encoding operation(s) on the source video sequence to generate a first encoded video sequence. During playback, the media title is switchable between a decoded version of the first encoded video sequence and a decoded version of a second encoded video sequence at the key frame location(s).

The invention generates encoded data in which image quality degradation of regions of the frame of interest that have not been encoded is suppressed. For this, an apparatus comprises a quantizing unit which quantizes image data of a frame in accordance with a quantization parameter, every predetermined block set in advance, an encoding unit which encodes quantized data, a quantization control unit which controls the quantization parameter such that a code amount approaches a target code amount, and a scene change detecting unit which detects a scene change. The quantization control unit has at least two control methods, applies a first quantization control method when starting encoding of a frame, and, in a case where the scene change detecting unit detects a scene change, switches to a second quantization control method from the first quantization control method.

An attention position detection section detects an attention position of a user to a reproduction image of moving image data. Image-related information indicating a position of a virtual division area in which the reproduction image is virtually divided and an importance level of the virtual division area is associated with the moving image data. A reproduction control section determines the importance level of the virtual division area corresponding to the attention position detected by the attention position detection section and controls a reproduction operation of the moving image data in accordance with the determined importance level. For example, the reproduction control section sets a larger number of images to be thinned in the reproduction operation as the importance level becomes lower so as to make the reproduction speed faster. The user can control the reproduction operation only by moving the attention position and easily perform the appropriate reproduction operation.
