The present application discloses a method, system, device and storage medium for playing HLS streaming media, and relates to the technical field of streaming media playing. The URL addresses of all TS segments of the HLS streaming media to be played are obtained by parsing the M3U8 index file through the main thread. In the process of parsing the M3U8 index file through the main thread, a sub-thread not exceeding the preset number of newly created sub-threads is created to concurrently open the URL address obtained by parsing, and the URL address corresponding to the first TS segment is opened. The download thread downloads the playback data corresponding to each TS segment from each opened URL address in sequence. The present application can improve the start-up speed and effectively avoid the waste of network bandwidth, playback jams and excessive occupation of system resources.

This disclosure provides a video synthesis method, apparatus, device, medium, and product. The method includes: performing image segmentation on image frames in a video to be processed to obtain a region image corresponding to a target object and a background image excluding the region image; determining a mirror image corresponding to the region image; expanding the region image in a first expansion direction to obtain at least one first expanded image; the at least one first expanded image includes the region image; expanding the mirror image in a second expansion direction to obtain at least one second expanded image; rendering the background image, at least one second expanded image, and at least one first expanded image to obtain a target rendered image at the end of rendering; and synthesizing the target rendered image corresponding to the image frame to obtain a target video corresponding to the video to be processed. By detecting and expanding video images, the method solves the problem of relatively simple video processing methods.

The invention discloses a method for automatically generating a short video based on watching behavior data, and belongs to the technical field of video production. The invention discloses a method for automatically generating a short video based on watching behavior data. The method comprises the following steps: slicing a video into a plurality of video clips with the same length; performing multi-dimensional value analysis on each video clip, wherein the value of each video clip forms a value weight matrix; calculating the value weight of each video clip based on the one-dimensional matrix and the trained clip value model; obtaining watching behavior information of the user; calculating a standardized value score of the video clip based on the viewing behavior information of the user and the value weight matrix; and generating a simplified video according to the standardized value score of the video clip and the video clip. According to the invention, the efficiency of searching and watching the knowledge point video by the user is improved.

The invention provides a display device and a media asset playing method, the display device comprises a display and a controller, the controller comprises an application layer and a bottom layer, the application layer is provided with a video playing program, and the bottom layer is provided with a player and a playing agent; the controller is configured as follows: a video playing program of the application layer receives an input media resource playing instruction; in response to the media asset playing instruction, a playing agent is started, and the playing agent is configured to download streaming media fragments of target media assets corresponding to the media asset playing instruction into a cache after being started; the player is started, a playing instruction of the target media asset is sent to the player, the playing instruction comprises a playing agent address and a media asset identifier of the target media asset, and the player is configured to control a playing agent to open the streaming media fragment through a connection interface of the http protocol and control the playing agent to return video streaming data of the streaming media fragment through a reading interface of the http protocol. The media resource playing speed of the display device is improved.

Embodiments of the present application disclose an animation playing method and device, electronic equipment and computer storage medium; in the embodiments of the present application, the trigger instruction corresponding to the icon of target animation is acquired;According to the trigger instruction, the animation file corresponding to the target animation is acquired, and the state of the icon is determined;If the state of the icon is the first frame state, the data corresponding to the target image in the target animation is filtered out from the animation file, and the target image is the image in the target animation except the first frame image;According to the playing order of the target image in the target animation, the data corresponding to the target image is decoded to obtain the decoded data of the target image;According to the decoded data, the target image is rendered, and the target animation is played according to the target image.The embodiments of the present application can improve the speed of animation playing.

The invention relates to the technical field of traffic, in particular to a locomotive information display method, device and equipment, a storage medium and a computer program.The method comprises the steps that a locomotive state information display page is displayed, and the locomotive state information display page comprises a locomotive video display area and a locomotive state information display area; acquiring locomotive state information of the target locomotive; calling a video receiving and processing module, indicating the video receiving and processing module to pull video stream data of the target locomotive, and generating a video playing window according to the video stream data; displaying the locomotive state information to a locomotive state information display area; and embedding the video playing window into the locomotive video display area. According to the technical scheme, the locomotive state information display page can display the locomotive monitoring video and the locomotive state information at the same time, and the monitoring efficiency is improved.
