With the development of video technology and diversification of video application scenes, the concept of interactive video has been proposed in recent years, and has received more and more attention from users. The interactive video means that in the process of watching the video, the original mode that audiences can only watch the video content passively is broken through, interactivity is increased in a certain mode, and users can participate in video interaction, so that different video watching experiences are presented.
The core of the realization of the interactive video is the change of video content, and the user can have other interactive interaction besides passive watching. Generally, interactive video content comprises a plurality of content plot lines, each plot line has independent branch video content, each branch video content is independent from each other and can be played independently, and a user can watch favorite plot line content through interactive information displayed on an interface and interactive operation of the interactive interface, so that interactivity is increased, and different watching experience is provided. Since the interactive video includes a plurality of branch videos, the switching requirement of different branch videos is necessarily involved in the interactive operation process. The fluency of switching different branches of the interactive video is also an important link for the viewing experience of the interactive video. At present, there are two common methods, one is to use a player, close the current video and then reload and play the next branch video when the branch video needs to be switched; the other is to start a plurality of players, one of which plays the current video, and the other players load other alternative branch videos in advance and enter a pause waiting playing state, and when the switching is triggered, the player is switched to the corresponding alternative video player to play. The first method has less resource occupation, the fluency of the switching branch video depends on the size of the video and the quality of the network, and the switching fluency is insufficient; the second method starts a plurality of players, the resource occupation is large, although the switching is smooth, the number of the players depends on the number of the next-level branch videos, and because it is not known which branch video will be played next before the switching, the number of players to be started by how many alternative branch videos is only suitable for the situation that the number of the same-level branch videos is small, if the number of the same-level branch videos is too large, the number of the players to be started is large, and the system resource overhead is inevitably too large.

after the current playing video triggers an interaction condition, the playing interface displays an interaction interface, a user carries out interaction response, and when the user selects a next branch video to be played, the video loading unit carries out video loading; and repeating the steps until the interactive video is played according to the time line.
In an embodiment of the present invention, the video loading unit performing video loading includes:
and inquiring from the video pre-cache control unit, if the video is not in the cache, directly downloading the video data from the video server by the video loading unit, if the video is in the cache, directly reading the cache data from the pre-cache data reading unit by the video pre-loading unit, and simultaneously starting a video downloading cache task to continue downloading cache of the un-downloaded data by the video pre-cache control unit, so that the cache file reading, the video downloading and the downloading data writing into the cache file are mutually connected in series to form the caching and playing of streaming data. Because the pre-cached data is the data downloaded in advance in the last video playing process, the data is directly read from the cached file when being played, the efficiency is the same as that of the local file, so that the time consumed by server connection, DNS analysis and data downloading is saved, the playing can be started at millisecond level, the switching is fast and smooth without pause, and the seamless switching of the branch videos is realized.
In one embodiment of the invention, each pre-cached video playing address corresponds to a cache file with a unique identifier; the pre-cache data reading unit reads the video data in the cached cache file, finds the corresponding cache file according to the unique identifier of the cache file, and reads the video data in a file stream mode. Video playing data of a common player are stored in an operating memory (RAM), and file storage (ROM) space is occupied by pre-caching the data in a streaming cache file in the embodiment of the invention, so that the consumption of the operating memory (RAM) of a program is reduced. The running memory (RAM) is configured memory such as 16G, and the file storage space (RAM) is configured hard disk storage space such as 512G. The consumption of the program operation memory can be greatly reduced through the stream file form setting, and the program operation efficiency is improved.
In an embodiment of the present invention, the video playing module further includes a video parsing unit, which decapsulates the loaded audio/video data and parses the coding format, so as to obtain audio data, video data, and other configuration information written into the code stream after parsing.

The comparison reference value of the network downloading code rate lower than or higher than the playing video code rate can be set according to actual requirements, for example, the caching task is suspended when the code rate is lower than 1 time, and the caching task is recovered when the code rate is higher than 2 times. The video downloading cache module can specify the size of the cache data volume and the downloading rate of each cache task, and the cache is stopped when the downloaded data of the cache tasks reaches the specified data volume.
In an embodiment of the present invention, the pre-cache data reading unit performs parallel access on a single file or multiple files, each file corresponds to one reading task, all the tasks are independent of each other, and the reading of the files is performed sequentially from the file head to the file tail.

and S3, the video pre-caching control unit starts 3 video downloading caching tasks, and simultaneously appoints the caching data size of each downloading caching task to be 5M. When the network downloading rate is lower than the code rate of the H1 video being played, the B1, B2 and B3 video downloading cache tasks are paused, when the network downloading rate is higher than 2.5 times the code rate of the video being played, the downloading cache tasks are resumed, and simultaneously the downloading rate of each downloading task is set to be 0.5 times the code rate, so that enough network bandwidth is reserved for the video being played when the downloading cache tasks are operated, and the smoothness of the video being played at present is ensured. And when the video data amount downloaded by the video cache downloading task reaches 5M, stopping the task.
S4, when the user performs the interactive operation, the user selects one of the three branch videos, which is assumed to be B2. Then the video loading unit of the player module immediately queries whether the B2 has a cache from the video cache control unit, if so, the video preloading unit reads the cache file data of the B2 video from the pre-cache data reading unit, the data reading is performed from the file head to the file tail, meanwhile, the video pre-cache control unit starts the download cache task of the B2 video to continue the download cache of the video data after 5M, and the cache write of the download data is performed from the file tail for splicing write. Through the steps, the reading of the cache file, the downloading of the video data and the writing of the downloaded data into the cache file are connected in series, and the playing of streaming data is formed. Therefore, the fast starting of the B2 video is realized, and the seamless cutting effect is achieved.
S5, after the B2 video starts to be played, the interactive chapter information processing module processes the interactive chapter information of the next node branch to obtain branch videos C1, C2 and C3 of the next node;
and repeating S2 to S4 for the branch videos C1, C2 and C3 until all the interactive videos are played in a time line.
