The present application provides a video processing method and apparatus. The video processing method includes: obtaining a video to be processed; decoding the video to obtain a set of target video frames, wherein the set of target video frames comprise a target recognition image; determining video position information indicating positions of the set of target video frames in the video, image position information indicating positions of the target recognition image in the set of target video frames, and a target link corresponding to the target recognition image; and storing the video position information, the image position information, the target link, and a corresponding relationship among them, and binding the same to the video. The video processing method provided in the present application facilitates a user in quickly jumping to a target link, simplifies complicated processes, and improves user experience.

Video processing method and apparatus

The present disclosure provides techniques of preloading video data. The techniques comprises acquiring a video to be played; acquiring information indicative of historical behaviors of users who watched the video; segmenting the video into a plurality of video segments; determining a historical search rate corresponding to each of the plurality of video segments based on the information indicative of the historical behaviors of the users; and determining a video segment among the plurality of video segments as a first target video segment based on the historical search rate corresponding to each of the plurality of video segments, wherein the video segment has a historical search rate greater than or equal to a preset probability threshold; and preloading the first target video segment of the video.

Video loading method and device

Techniques for displaying comments relative to a video frame are described herein. The disclosed techniques include receiving a frame of a video; receiving bullet screen data comprising a plurality of comments associated with the frame; receiving a mask frame data segment corresponding to the frame; determining a mask area based on the mask frame data segment, wherein the mask area corresponds to a main area of the frame; and displaying the plurality of comments relative to the frame in areas other than the mask area.

Method of displaying comment information, computing device, and readable storage medium

Techniques of generating and displaying an attention curve relative to a progress bar are described in the present disclosure. The disclosed techniques include sending a request for acquiring a target video that is divided into a plurality of predetermined time period; receiving data comprising a number of comment events and a number of drag progress bar events within each preset time period of the target video; determining an attention value corresponding each predetermined time period based on the number of the comment events and the number of the drag progress bar events within each predetermined time period of the target video; generating an attention curve based on a plurality of attention values corresponding to the plurality of predetermined time periods of the target video; and displaying the attention curve relative to a progress bar, wherein amplitude values of the attention curve relative to the progress bar are in proportion to the plurality of attention values corresponding to the plurality of predetermined time periods of the target video.

Method and device of displaying a progress bar, computing device, and readable storage medium

Techniques for processing a multimedia file in real-time are described herein. The disclosed techniques include receiving a plurality of fragments of a multimedia file by a data stream conversion service, wherein the data stream conversion service receives a first fragment containing metadata of the multimedia file and then receives other fragments of the multimedia file in a predetermined order; sending a notification message to a message queue by the data stream conversion service in response to receiving the first fragment, wherein the notification message includes the metadata of the multimedia file and a corresponding Hyper Text Transfer Protocol (HTTP) interface address; obtaining the notification message from the message queue by an encoding and decoding service; and processing the other fragments of the multimedia file based at least in part on the notification message by the encoding and decoding service.
