Video decoding method and apparatus, electronic device, computer-readable storage medium, and computer program product

A video decoding apparatus, comprising:

• at least one memory configured to store computer program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code comprising:
• video stream analysis code configured to cause at least one of the at least one processor to perform video stream analysis on a to-be-decoded video to obtain a frame data packet of a first plurality of video frames in the to-be-decoded video, wherein the video stream analysis comprises parsing an encapsulated data packet that encapsulates video frame information in the to-be-decoded video;
• first determining code configured to cause at least one of the at least one processor to determine a plurality of frame types of the first plurality of video frames based on frame attribute information in the frame data packet, a frame type comprising a key frame and a non-key frame;
• second determining code configured to cause at least one of the at least one processor to determine a first plurality of target sampling frames from the to-be-decoded video based on a first quantity of a plurality of key frames, the first plurality of target sampling frames being a second plurality of video frames configured for providing rendering data when rendering the to-be-decoded video, and the rendering data being stored in a plurality of frame buffers corresponding to the first plurality of target sampling frames;
• obtaining code configured to cause at least one of the at least one processor to obtain the rendering data from the plurality of frame buffers;
• and
• video decoding code configured to cause at least one of the at least one processor to perform video decoding on the to-be-decoded video based on the rendering data to obtain a decoded video corresponding to the to-be-decoded video.

A non-transitory computer-readable storage medium, storing computer code which, when executed by at least one processor, causes the at least one processor to at least:

• perform video stream analysis on a to-be-decoded video to obtain a frame data packet of a first plurality of video frames in the to-be-decoded video, wherein the video stream analysis comprises parsing an encapsulated data packet that encapsulates video frame information in the to-be-decoded video;
• determine a plurality of frame types of the first plurality of video frames based on frame attribute information in the frame data packet, a frame type comprising a key frame and a non-key frame;
• determine a first plurality of target sampling frames from the to-be-decoded video based on a first quantity of a plurality of key frames, the first plurality of target sampling frames being a second plurality of video frames configured for providing rendering data when rendering the to-be-decoded video, and the rendering data being stored in a plurality of frame buffers corresponding to the first plurality of target sampling frames;
• obtain the rendering data from the plurality of frame buffers;
• and
• perform video decoding on the to-be-decoded video based on the rendering data to obtain a decoded video corresponding to the to-be-decoded video.
