Video seek display processing method and apparatus

An electronic device, comprising a memory and a processor, wherein

• the memory is configured to store computer program instructions;
• and
• the processor is configured to execute the computer program instructions to cause the electronic device to:
• obtain a seek request triggered on a timeline for video preview, wherein the seek request is configured to request a seek from a first timeline position to a second timeline position;
• perform matching based on the second timeline position and individual decoded video frames in a cache queue to obtain a matching result;
• clear the cache queue, controlling a decoder to perform decoding based on the second timeline position, and storing a decoded video frame into the cache queue, in response to a first condition or a second condition being met, or, skipping clearing the cache queue in response to a third condition or a fourth condition being met, wherein the first condition is that the seek request indicates a forward seek and the matching result indicates that the cache queue does not comprise a video frame at the second timeline position, the second condition is that a seek direction indicates a backward seek, the matching result indicates that the cache queue does not comprise the video frame at the second timeline position, and the video frame at the second timeline position and the cache queue do not belong to a same group of pictures, the third condition is that the cache queue comprises the video frame at the second timeline position, and the fourth condition is that the seek direction indicates a backward seek, the matching result indicates that the cache queue does not comprise the video frame at the second timeline position, and the video frame at the second timeline position and the cache queue belong to a same group of pictures;
• and
• read from the cache queue, based on the met condition and a seek mode corresponding to the seek request, the video frame at the second timeline position or any video frame within a tolerance range for the second timeline position, and rendering and displaying the read video frame.

A non-transitory readable storage medium having computer program instructions stored thereon,

• which, when executed by at least one processor of an electronic device, cause the electronic device to:
• obtain a seek request triggered on a timeline for video preview, wherein the seek request is configured to request a seek from a first timeline position to a second timeline position;
• perform matching based on the second timeline position and individual decoded video frames in a cache queue to obtain a matching result;
• clear the cache queue, controlling a decoder to perform decoding based on the second timeline position, and storing a decoded video frame into the cache queue, in response to a first condition or a second condition being met, or, skipping clearing the cache queue in response to a third condition or a fourth condition being met, wherein the first condition is that the seek request indicates a forward seek and the matching result indicates that the cache queue does not comprise a video frame at the second timeline position, the second condition is that a seek direction indicates a backward seek, the matching result indicates that the cache queue does not comprise the video frame at the second timeline position, and the video frame at the second timeline position and the cache queue do not belong to a same group of pictures, the third condition is that the cache queue comprises the video frame at the second timeline position, and the fourth condition is that the seek direction indicates a backward seek, the matching result indicates that the cache queue does not comprise the video frame at the second timeline position, and the video frame at the second timeline position and the cache queue belong to a same group of pictures;
• and
• read from the cache queue, based on the met condition and a seek mode corresponding to the seek request, the video frame at the second timeline position or any video frame within a tolerance range for the second timeline position, and rendering and displaying the read video frame.
