and if the node video of the current node is cached to a preset percentage, starting to play the node video content, and pausing the caching of the node videos in the other node containers.
Specifically, when a user starts to view a video, the user enters a playing page, 3 child node containers are preloaded, video contents corresponding to the loaded video nodes are sequentially and pre-cached in the containers according to the sequence of the video nodes, and the user starts to play automatically after the video in the current display node container is cached to a playable percentage. And preferentially caching the video of the current node, and starting to cache the videos of the rest nodes after the current node can play.
When the video resource is obtained, the video resource is obtained from the local cache through video management, if the video exists in the local cache, the video resource is directly loaded to the memory, otherwise, the video resource is obtained from the network.
And S3, obtaining the sliding distance for sliding the video node, judging whether the sliding distance is larger than a threshold value, if so, taking the selected video node after sliding as the current node, and if the current node does not exist in the node container, replacing the node video which is farthest from the current node in the node container with the node video of the current node.
Wherein the obtaining of the sliding distance for sliding the video node comprises:
adjusting the position of the video node in real time by sliding the video node;
and at the end of the sliding, calculating a sliding distance according to the initial touch position of the sliding and the end touch position of the sliding.
Specifically, referring to fig. 3, node containers are created in the circular switching module, each node container can independently display the content of a video, when a user slides a screen up and down, Y axes of all nodes are actively updated, a sliding distance is calculated according to the position initially touched by the user and the position currently touched by the user, a difference value is calculated according to the distance given to the Y axes of all nodes in the current video list, and a sliding phenomenon generated by all current video nodes according to the position touched by the user is shown.
Wherein, the judging whether the sliding distance is greater than a threshold value, if so, the specifically including, as the current node, the video node selected after sliding:

if not, reducing the sliding distance until all the video nodes recover to the positions before sliding, and playing the sliding animation in the sliding process.
Specifically, referring to fig. 3 and 4, when the user stops sliding, it is determined whether the display of switching the next node is reached according to the sliding distance, and if the sliding distance is less than one half of the height of the current node container, all nodes are restored; the method mainly comprises the steps that moving animations of all nodes in a video list are mainly controlled in a moving module, the positions of the nodes are set, the sliding phenomenon of the video list is shown according to the sliding distance of a user, 5 nodes can be set in the currently displayed video list, the positions of all the nodes can be updated rapidly through a small number of nodes, massive calculation is avoided, videos in the nodes which are not displayed are replaced through data processing after the moving is finished, the user can feel smooth sliding experience through playing of the animations, when the touch distance of the user is large enough, the next video is switched, and 0.25S sliding animations are set when the next video is switched; when the distance is not enough, the original position is restored, and the sliding animation needs to be played, so that the user can have continuous experience visually.
And taking the selected video node after sliding as a current node, and replacing the node video which is farthest from the current node in the node container with the node video of the current node if the current node does not exist in the node container.
Specifically, if the user slides upwards and takes the selected video node after sliding as the current node, whether the current node exists in the node container is judged, if yes, the node in the node container is not modified, if not, the node video which is farthest away from the current node in the node container is replaced by the node video of the current node, for example, the current node is a third video node, the current node is replaced by a fourth video node after upwards rolling is completed, the position of the first video node is replaced by the fourth video node after sliding is completed, and the video in the node is correspondingly replaced through data processing; if the user slides downwards, the fourth video node is reset and replaced by the first video node, and the video data processing in the node is the same as the upward sliding processing; after the setting is finished, the video circulating carousel can be realized, and the repeated establishment and destruction of a large number of nodes are reduced.
And S4, judging whether the video nodes of the first preset number of the batch are loaded and played completely, if so, acquiring the video nodes of the first preset number of the next batch, adding the newly acquired video nodes into the corresponding node container, and loading and playing.
Specifically, only after the current video in the circular carousel is completely loaded and played, the subsequent videos are continuously loaded according to the first preset number, otherwise, no new video is loaded, if the first preset number is not set, all videos need to be loaded at one time or only one video needs to be loaded at each time, the network occupation for loading all videos at one time is high, and the memory occupation of the videos is large, so that the memory bottleneck is easily caused; only one video is loaded, the video is required to be requested when played every time, video blocking is easily caused under the condition of large network fluctuation, and poor user experience is caused.
Example two
Referring to fig. 5, the difference between the present embodiment and the first embodiment is that how to store the loaded video is further defined, specifically:
and judging whether the number of the node videos stored in the cache exceeds a number threshold, and if so, deleting the node videos which are not played for the longest time in the cache.
In this embodiment, the video can be played and cached locally when being loaded. When the number of the videos which are cached at the same time currently exceeds a threshold value, whether the time from the video to the last playing is longest in all the videos is judged, if the time is longest, the video is cleared from a current memory, and the video is preloaded in advance when the video is used next time.
