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

The present disclosure describes techniques of processing information flow and synchronously displaying image s, mask frames and comment information. According to the present disclosure, a system processes a first information stream uploaded by a stream pushing terminal to obtain a frame image and mask frame data, the mask frame data corresponding to the frame image and identifying a timestamp offset indicative of a time difference between the mask frame data and a playing timestamp of the frame image. The system synthesizes the frame image and the mask frame data to generate a second information stream; and output the second information stream to a client for synchronously displaying the image frame, a corresponding mask frame, and the comment information.

Method and system of processing information flow and method of displaying comment information

The present disclosure describes techniques for implementing user interface interaction. The disclosed techniques comprise playing a video on an interface; monitoring user input performed on the interface; determining a target frame based at least in part on the user input; determining a location where the user input is performed on the interface; determining whether the location of the user input is in a predetermined area of the target frame, wherein the predetermined area is associated with at least one object in the target frame; and implementing an operation associated with the at least one object in response to determining that the location of the user input is in the predetermined area of the target frame.

User interface interaction method and system

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.
