1. A method for generating live streaming video data, comprising:
obtaining live broadcasting video data;
identifying a target object in a first video frame, wherein the first video frame is any video frame comprised in the live broadcasting video data;
determining a target area based on the target object in the first video frame, wherein the target area is an area not to be occluded by any item;
encoding data indicative of the target area based on a predetermined format for supplementary enhancement information to obtain encoded target area data; and
adding the encoded target area data to a data packet corresponding to the first video frame, wherein the data packet is encoded based on a predetermined video data format, wherein the predetermined video data format and the predetermined format for supplementary enhancement information are mutually compatible data encoding formats, wherein a bullet screen mask corresponding to the video frame is to be generated based on extracting the encoded target area data, wherein one or more comments associated with the video frame are to be displayed on the bullet screen mask, and wherein the bullet screen mask is configured to control display visibility of the one or more comments.
