Problems solved by technology

[0002] At present, when caching video streams, all the data frames in the video stream are generally stored together. When a target frame needs to be located, it is necessary to traverse all the data frames between the current frame and the target frame. To locate the target frame, if there are many data frames between the current frame and the target frame, it will take a long time to realize the positioning of the target frame. In other words, for the video cached by the current video caching scheme Stream, it takes a long time to realize the positioning of the data frame, and the positioning efficiency of the data frame is low
[0003] Moreover, when caching each frame of data frames, memory is first applied for, then memory is allocated, and finally stored based on the allocated memory, that is to say, for each frame, memory needs to be separately applied and allocated for processing Cache, however, frequent memory allocation may make some smaller memory slices unused, thereby increasing the degree of fragmentation of memory, resulting in a decrease in the utilization of memory resources. In addition, frequent application, access, allocation, etc. A series of memory The operation will take a long time and the cache efficiency is low
[0004] It can be seen that for the current video caching scheme, the degree of memory fragmentation is high and the caching efficiency is low, and it takes a long time to locate the data frame, and the positioning efficiency of the data frame is low

Abstract

The invention discloses a video caching method and device and a readable storage medium, and belongs to the technical field of data processing. The video caching method comprises the steps of when a to-be-cached target video stream is obtained, obtaining a target idle memory from an idle memory buffer queue to buffer a target video stream according to separation of an I frame and a non-I frame. The memory in the idle memory buffer queue is the idle memory obtained after the cached video data is released, memory multiplexing can be realized by buffering the target video stream through the idlememory in the idle memory buffer queue; therefore, frequent memory operations are reduced, the memory fragmentation degree is reduced, the video caching efficiency is improved, separated storage of the I frame and the B frame and the P frame is realized for the target video stream, subsequent positioning of the data frame is facilitated, and the positioning efficiency of the data frame is improved.

technical field [0001] The invention relates to the technical field of data processing, in particular to a video caching method, device and readable storage medium. Background technique [0002] At present, when caching video streams, all the data frames in the video stream are generally stored together. When a target frame needs to be located, it is necessary to traverse all the data frames between the current frame and the target frame. To locate the target frame, if there are many data frames between the current frame and the target frame, it will take a long time to realize the positioning of the target frame. In other words, for the video cached by the current video caching scheme Stream, it takes a long time to realize the positioning of the data frame, and the positioning efficiency of the data frame is low. [0003] Moreover, when caching each frame of data frames, memory is first applied for, then memory is allocated, and finally stored based on the allocated memor...
