Method and device for generating live streaming video data and method and device for playing live streaming video

A method for playing live streaming video, comprising:

• receiving live streaming video data comprising video frames and corresponding bullet screen data, wherein the corresponding bullet screen data comprise comments to be presented relative to the video frames;
• parsing data associated with a video frame among the video frames comprised in the live streaming video data, wherein the data associated with the video frame further comprise target area data encoded based on a predetermined format for supplementary enhancement information, the predetermined format for supplementary enhancement information is compatible with a predetermined video data format for encoding a data packet corresponding to the video frame, and the target area data comprise data indicative of a target area corresponding to a target object in the video frame;
• extracting the data indicative of the target area corresponding to the target object in the video frame;
• generating a bullet screen mask corresponding to the video frame based on the target area;
• and
• displaying at least one comment among the comments associated with and relative to the video frame on the bullet screen mask while displaying the video frame.

A system of generating live streaming video data, comprising:

• at least a processor;
• and
• at least a memory communicatively coupled to the at least a processor to configure the at least a processor to perform operations 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, and wherein the predetermined video data format and the predetermined format for supplementary enhancement information are mutually compatible data encoding formats.

A non-transitory computer-readable storage medium bearing computer-readable instructions that upon execution on a computing device cause the computing device at least to perform operations 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, and wherein the predetermined video data format and the predetermined format for supplementary enhancement information are mutually compatible data encoding formats.
