Method and apparatus for determining live streaming keyframe, storage medium, and electronic device

An electronic device, comprising a processor and a memory, wherein the memory stores a computer program, and when the processor executes the computer program, the electronic device is caused to:

• perform, by using a feature extraction module, feature extraction on a current captured frame of target live streaming, to obtain a feature vector of the current captured frame, wherein a frame sequence number corresponding to the current captured frame is a first sequence number;
• store the feature vector of the current captured frame in a cache, and delete a target historical captured frame that is in the cache and that corresponds to the current captured frame, wherein a difference between the first sequence number and a target sequence number corresponding to the target historical captured frame is a target quantity;
• read, from the cache by using a keyframe calculation module, a feature vector of a plurality of captured frames whose corresponding frame sequence numbers are from a second sequence number to the first sequence number, and determine at least one keyframe based on the feature vector of the plurality of captured frames, wherein a difference between the first sequence number and the second sequence number is the target quantity minus one, and a capture time of a captured frame corresponding to the second sequence number is earlier than a capture time of a captured frame corresponding to the first sequence number;
• and
• if the current captured frame is in the at least one keyframe, determine that the current captured frame is a keyframe.

A non-transitory storage medium storing a computer program, which when executed by a processor causes the processor to:

• perform, by using a feature extraction module, feature extraction on a current captured frame of target live streaming, to obtain a feature vector of the current captured frame, wherein a frame sequence number corresponding to the current captured frame is a first sequence number;
• store the feature vector of the current captured frame in a cache, and delete a target historical captured frame that is in the cache and that corresponds to the current captured frame, wherein a difference between the first sequence number and a target sequence number corresponding to the target historical captured frame is a target quantity;
• read, from the cache by using a keyframe calculation module, a feature vector of a plurality of captured frames whose corresponding frame sequence numbers are from a second sequence number to the first sequence number, and determine at least one keyframe based on the feature vector of the plurality of captured frames, wherein a difference between the first sequence number and the second sequence number is the target quantity minus one, and a capture time of a captured frame corresponding to the second sequence number is earlier than a capture time of a captured frame corresponding to the first sequence number;
• and
• if the current captured frame is in the at least one keyframe, determine that the current captured frame is a keyframe.
