The invention provides a video management pushing method based on a radio and television private network, which comprises the following steps of:
step S110, processing the first video information streams of the multiple data sources obtained at the current time to form second video information streams in a preset format, capturing first basic metadata of each video information stream, and updating the basic metadata at the previous time according to the captured first basic metadata at the current time to obtain updated second basic metadata. The data source in the invention can be a streaming media platform, and the streaming media platform can be, for example, an Tencent video platform, an Aiqiyi video platform, and the like. The first video information stream may be considered to be directly obtained from the streaming media platform, and the first video information stream may include a plurality of pieces of video information, for example, two videos (a first video and a second video) are added to one streaming media platform, where the two pieces of video information are the first video and the second video respectively, and the first video information stream includes video information corresponding to the first video and the second video.
The format of the video stream may be varied, for example ASF format, NAVI format, AVI format, MPEG1-4 format, WMV format, 3GP format MKV format, FLV format, F4V format, RMVB format, etc. Each format has its own suitable application scenario. Because the formats of different streaming media platforms may be different, the present invention performs a unified conversion process after obtaining the first video information stream sent by each streaming media platform, so as to obtain the second video information stream with a preset format. The invention can be provided with a database, and the second video information stream and the video information are stored in the corresponding database after the second video information stream and the video information in the preset format are generated.
The metadata is in various forms, and is mainly used to describe video information streams, and for the definition of video information streams, one video information stream corresponds to one video information, that is, one video information stream corresponds to one video information. It can also be considered that one video information stream corresponds to a plurality of video information, i.e. one video information stream comprises two video information, since a video information stream may be composed of a plurality of video information segments. Each video information may have metadata corresponding thereto, and the metadata may be considered to include index information of the corresponding video information and may also include introduction information to the corresponding video information.
According to the technical scheme provided by the invention, the basic metadata at the previous moment is updated according to the first basic metadata captured at the current moment, so that the updated second basic metadata is obtained. The first base metadata may include index information of a plurality of videos, for example, the index information of the first video is 101, the index information of the second video is 102, at this time, the index information of the first video and the second video may be index information of the first video and the second video at a previous streaming media platform, at this time, the index information of the video information of all platforms needs to be processed uniformly, and at this time, the index information of the first video is 101, the index information of the second video is 102, and the index information of the video information of all platforms are processed uniformly. The base metadata at the previous time is data obtained by previously and uniformly processing the index information of the video information of all the platforms, for example, if the index information corresponding to the last video information in the base metadata at the previous time is 7931, the updated second base metadata includes that the index information of the first video is 7932 and the index information of the second video is 7933, that is, the index information of the first video is updated from 101 to 7932, and the index information of the second video is updated from 102 to 7933. Through the above manner, the basic metadata at the previous moment is updated according to the first basic metadata captured at the current moment, so that the updated second basic metadata is obtained.
Step S120, processing the live third video information stream to form a second video information stream in a preset format, storing the second video information stream in real time, adding a time tag, and generating, based on the time tag, an updated third basic metadata by updating the second basic metadata. The present invention has various ways to obtain video information streams, and in step S110, the video information in the streaming media platform is mainly obtained, and in step S120, the live video information is mainly obtained. Such as live video information of a television station, live information of software, etc.
Because the formats of the video information streams in different live broadcasts can be various, the second video information streams sent by the live broadcast platforms are uniformly converted to obtain the second video information streams with the preset format.
According to the technical scheme provided by the invention, the second basic metadata is updated according to the time tag, so that the updated second basic metadata is obtained. For example, the index information of the last video information in the second base metadata is 7933. The second video stream processed by the third video stream to form the preset format includes a third video and a fourth video, and the time stamp of the third video may be 2021.10.01.16: 09, the time stamp of the fourth video may be 2021.10.01.17: at this time, the third video and the fourth video are sorted according to the time tags, and at this time, the second basic metadata is updated according to the time tags of the third video and the fourth video to obtain third basic metadata, where the third basic metadata includes index information 7934 of the third video and index information 7935 of the fourth video. That is, the third base metadata includes index information 7932 of the first video, index information 7933 of the second video, index information 7934 of the third video, and index information 7935 of the fourth video.
Step S130, selecting a corresponding second video information stream based on the received user selected data and the third basic metadata, and pushing the selected second video information stream to the target user side through the private radio and television network.
