Description
Technical Field
The present application relates to the field of computers, and in particular, to a video acquisition method and apparatus.
Background
With the continuous progress of science and technology, watching movie and television videos is becoming one of the more popular entertainment ways. In the prior art, video downloading is completed by a Content Delivery Network (CDN), and a video CDN refers to a set of CDN systems capable of providing video streaming services, and generally includes systems such as storage, synchronization, source return, scheduling, and video file parsing. The basic principle of the CDN is to widely adopt various cache servers (CDN edge nodes), distribute the cache servers to a region or a network where user access is relatively concentrated, and when a user accesses a website, point the user access to a cache server that is closest to the working state by using a global load technology, and directly respond to a user request by the cache server.
When a user watches videos at a client, a video stream file is downloaded in the following mode, after the client initiates a request, an analysis list of video files is firstly obtained from a video file analysis server, and then downloading is carried out in sequence according to the files in the list. When downloading each file, the client needs to make a request to the scheduler once, and downloads the file from the designated CDN edge node according to the result returned by the scheduler. If the downloading request of the file reaches the edge node, and the node stores the file, directly spitting data to the client; if the file is not stored, a file downloading request needs to be sent to an upstream node, data is spitted to a client after the data of the upstream node is received, the file is stored locally, and if the same file request exists next time, the file does not need to be requested upstream. If the upstream node does not have the file, a request needs to be sent upstream of the upstream node. The link of the download request finally forms a tree structure, the edge node is a leaf node of the tree, and the back source node is a middle node and a root store of the tree. The downloading mode of the tree-like hierarchical files is called a source return mode, and most of the files which are hot can be sent to the whole network by using the mode.
However, when the file requested by the client is not stored in the edge node, a download request needs to be sent to an upstream node at this time, which may cause problems of a long source return link and a slow source return speed, resulting in that the user cannot obtain the desired video file in time, the waiting time of the user is prolonged, and the user experience is greatly reduced.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below with reference to the accompanying drawings.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways than those described herein, and it will be appreciated by those skilled in the art that the present application may be practiced without departing from the spirit and scope of the present application, and that the present application is not limited to the specific embodiments disclosed below.
As described in the background art, when there is a client request, if the edge node does not store the file, and at this time, it needs to send a download request to an upstream node, there are problems of long backlog link and slow backlog speed. The inventors have also found that, generally speaking, if a file is newly online or is a relatively cold file, and the edge node is likely not to store the file, the user needs to wait for the file to be sourced back to the edge node for a long time; or if the file is large, such as a high-bit rate file, if the file starts to return to the source after the request of the client, the waiting time of the user is longer, and the user experience is greatly reduced. Although there are various optimization means for the transmission technology of the return source, when a client requests to download a certain video file, it still cannot be guaranteed that the file is stored in the edge node, and a user cannot acquire the file in time. Therefore, in the prior art, the user cannot obtain the desired video file in time due to the fact that the user cannot combine with the personal film watching habit of the user, and user experience is reduced.
Based on the above technical problem, embodiments of the present application provide a video obtaining method and apparatus, where a network address of a first video may be determined from video access data within a first preset time period, the network address of the first video is related to a viewing behavior of a user because the video access data is related to the viewing behavior of the user, and then a network address of a second video may be obtained according to the network address of the first video, a video server may download the second video according to the network address of the second video, where the second video and the first video belong to a same video set, the video set includes multiple videos having video contents with correlation, that is, the second video and the first video have a certain correlation, and the second video having correlation with the first video because the network address of the first video is related to the viewing behavior of the user, and also with respect to the user's view, is likely to be viewed by the user at a later time. Therefore, the network address of the related second video can be determined according to the watching behavior of the user, so that the second video is downloaded in advance by the video server, when the user needs to watch the second video, the second video can be directly sent out by the video server to the user without going back to the source through the superior node, and the user can watch the video which the user wants to watch more quickly, so that the waiting time of the user is shortened, and the experience of the user is further optimized.
In this embodiment, referring to fig. 1, a schematic structural diagram of a video acquisition system provided in this embodiment includes an origin server, a video server, and a client. The source server is located at a root node of the tree structure, video file resources are provided for the video servers at leaf nodes through the tree structure, the video servers at the leaf nodes are directly connected with the client and used for providing the video file resources for the client, and the video servers can store video files so that a user can download the video files from the video servers through the client.
In addition, the system can also comprise an analysis server, or an analysis module is arranged in the video server, and the analysis module or the analysis server is used for providing a film watching behavior analysis service for the user; the system may further include a meta-information server, or a meta-information module is disposed in the video server, where the meta-information server or the meta-information module is configured to store meta-information of the video, and the meta-information of the video includes an album to which the video belongs, the number of the albums to which the video belongs, and a playing time interval, for example, the video belongs to the 6 th album of the tv series a, and the playing time interval is from 10 th minute to 15 th minute. The video server, the analysis server and the meta-information server may be placed in the same video room, and certainly, the meta-information server may also be disposed outside the video room where the video server is located.
In the embodiment of the application, when a user wants to acquire a video file, a downloading request can be sent to a video server connected with the user through a client, and if the video file is stored in the video server, the video server can send the video file to the client; if the video server does not store the video file, the video server needs to acquire the video file from a video server located at an upstream node through a CDN system and then send the video file to the client.
For convenience of understanding, a video acquisition method and a video acquisition apparatus provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 2, a schematic flow chart of a video acquisition method provided in this embodiment of the present application is shown, and the method is applied to the above analysis server or an analysis module in a video server, and may include the following steps.
S101, determining a network address of a first video from video access data in a first preset time period.
In the embodiment of the application, the access log is stored in the video server, and the access log records the network address of the video when the user accesses the video once through the video server. The access log may include a network address, an access time, and the like of the accessed video, and the analysis server or an analysis module in the video server may collect the access log from the video server, so that the video access data may be obtained from the access log of the video server, and the video access data may be expressed as, for example, that the first user accesses the video one at 7 o 'clock and 10 o' clock. The first preset time period is not specifically limited herein, and may be, for example, 5 minutes granularity, and if the first preset time period is shorter, it may be considered to collect the access log of the user in real time. Therefore, at least one accessed video can be determined from the video access data, and the at least one accessed video is determined as a first video, and the network address of the first video refers to the network address of the at least one accessed video. It is understood that the network address may be considered a Uniform Resource Locator (URL).
In the embodiment of the present application, due to the limitation of the disk space of the video server, it may not be possible to determine all accessed videos as the first video, so S101 has various implementations. The first video may be determined according to the sequence of the access time, specifically, the videos are sorted according to the sequence of the access time, and the first N accessed videos are determined as the first video. The first video may also be randomly selected, and specifically, the network address of the first video may be randomly determined from the video access data within the first preset time period.
In another implementation manner of determining the first video, the first video may also be determined according to the number of accesses, and referring to fig. 3, a flowchart for determining the first video provided for the embodiment of the present application, that is, S101 may include the following steps.
S1011, acquiring video access data in a first preset time period; the video access data includes network addresses of a plurality of accessed videos that are accessed at least once.
In the embodiment of the application, when the user accesses the video, the access log records the video, so that the video access data comprises the network addresses of a plurality of accessed videos which are accessed at least once. For example, a video server stores a video one, a video two, a video three, a video four and a video five, within a preset time, the number of times that the video one is accessed is 100, the number of times that the video two is accessed is 120, the number of times that the video three is accessed is 115, the number of times that the video four is accessed is 200, and the number of times that the video five is accessed is 0, then the video access data includes the network addresses of the video one, the video two, the video three and the video four, and does not include the network address of the video five.
And S1012, sequencing the network addresses of the accessed videos from at least one according to the access times.
In the embodiment of the application, one video server can be accessed by one user for multiple times and can also be accessed by multiple users for multiple times, so that the network address of a certain video can be accessed for multiple times, and the application can sort all the network addresses of accessed videos according to the number of the access times. The more the video is accessed, the higher the ranking position of the video. Thus, the more the number of visits is, the more people watching the video are, the more the popularity of the video is, and the closer the combination of the watching action of the user is. For example, the four accessed videos are respectively recorded as video one, video two, video three and video four, the access times of the four accessed videos are respectively 100, 120, 115 and 200, the four accessed videos are sequentially ordered according to the access times, and the ordering result is video four, video two, video three and video one.
S1013, determining the network addresses of the first N accessed videos as the network address of the first video; n is a positive integer.
In the embodiment of the present application, due to the limitation of the disk space of the video server, the network addresses of the first N accessed videos may be determined as the network address of the first video. For example, the number of N may be 20, 5, or 8. The network address of the first 5 accessed videos may be determined as the network address of the first video.
In the embodiment of the present application, an analysis module in an analysis server or a video server may obtain a performance index of the video server, such as a remaining disk space. The N has positive correlation with the remaining disk space of the video server, and the larger the remaining disk space is, the larger the N is. Specifically, if the remaining disk space of the video server is large, a large value may be taken for N, and the number of network addresses of the first video is large; if the remaining disk space of the video server is small, a small value can be taken for N, and the number of network addresses of the first video is small.
S102, acquiring a network address of a second video according to the network address of the first video, so that the video server downloads the second video according to the network address of the second video.
In the embodiment of the present application, the second video and the first video belong to the same video set, and one video set includes a plurality of videos whose video contents have relevance. A video set comprises a plurality of videos, and the videos have a certain correlation and can all belong to the same album, such as the same movie or the same television show. The video information may be written into a database in the meta information server, and an index service may be established, where the video information may be a video set to which the video belongs, for example, the video information of the first video is the video set to which the first video belongs.
In the embodiment of the application, an analysis server or a video server with a built-in analysis module sends a query request to a meta information server or a meta information module in the video server, wherein the query request is used for querying a video set to which a first video belongs, and the query request comprises a network address of the first video; a meta information module in a meta information server or a video server determines a video set to which a first video belongs according to a network address of the first video, then acquires a network address of a second video from the video set, and sends the network address of the second video to an analysis server or an analysis module in the video server; an analysis module in the analysis server or the video server imitates the access behavior of a user and sends a downloading request to the video server, wherein the downloading request comprises the network address of the second video; and the video server requests to download the second video by utilizing the CDN system according to the network address of the second video so that the video server stores the second video. Therefore, when the user accesses the second video, the second video is stored in the local (video server), the time that the user waits for downloading for a long time is avoided, and the user experience is improved.
In this embodiment of the application, when N >1, network addresses of a plurality of second videos may be obtained according to network addresses of a plurality of first videos, respectively. For example, when N is 5, 5 video sets to which the first video belongs may be determined according to network addresses of the 5 first videos, and then network addresses of 5 second videos are obtained from the 5 video sets.
In an embodiment of the present application, for each first video, one or more videos can be determined. Specifically, each first video can determine one video, that is, one video, such as a second video, is obtained from a video set to which the first video belongs; each first video may also determine multiple videos, that is, multiple videos are obtained from a video set to which the first video belongs, for example, two videos, a second video and a third video are determined. For example, the number of the first videos is 5, and if each first video corresponds to one second video, the number of the second videos is also 5; if each first video corresponds to 2 videos, which are respectively recorded as a second video and a third video, the total number of the second video and the third video may be 10. Acquiring a network address of a second video and a network address of a third video according to the network address of the first video, so that the video server downloads the second video according to the network address of the second video and downloads the third video according to the network address of the third video; the third video and the first video belong to the same video set.
In the embodiment of the application, the number of the network addresses of a plurality of videos determined according to the first video can be dynamically determined according to the service index of the server. For example, the number of the determined network addresses of the plurality of videos may be a larger value if the remaining disk space of the video server is larger; if the remaining disk space of the video server is small, the number of the determined network addresses of the plurality of videos can be a small value.
In the embodiment of the present application, when N >1, since multiple first videos may belong to different video sets or albums, it may be determined which videos need to be preferentially selected to be returned to the source according to the popularity of the albums. If the album to which the video belongs is high in popularity, the album is watched by more people, and more videos belonging to the album can be downloaded, so that the use experience of the user is improved.
In embodiments of the present application, the videos in the collection are derived from videos in an album, which may include one or more target videos. Specifically, when the duration of the target video in the album is short, all the target videos in the album can be combined into one video set, the first video is the target video in the album, and then one album is a video set. When the target video in the album is long in duration, the target video can be sliced, one target video is sliced to obtain a plurality of sub-videos, all the sub-videos form a video set, and then the first video is the sub-video obtained by the target video. For example, if the duration of the target video is greater than 6 minutes, the target video is sliced, otherwise, the target video is not sliced.
In the embodiment of the application, if the duration of a single video in an album is long, the video can be sliced. One or more target videos may be included in the album, for example, if the album is a movie, the album may be considered to include a target video; if multiple videos belonging to the same drama can be regarded as belonging to the same album, the album is regarded as containing multiple target videos, and one episode of the drama is one target video. Slicing refers to dividing all target videos in an album into a plurality of sub-videos according to a playing sequence, and the time duration of the sub-videos is not limited herein, and may be, for example, 6 minutes. The network address of each sub-video is a URL.
In the embodiment of the present application, each sub-video needs to mark its start and end position of time in the target video, i.e. mark its playing time interval. If the album comprises a target video, the sub-video needs to mark the playing time interval of the sub-video in the target video; if the album includes a plurality of target videos, the sub-videos need to be marked with the target videos to which the sub-videos belong, and the playing time intervals of the sub-videos in the target videos to which the sub-videos belong need to be marked. The meta-information service can also write the video segment information into a database, wherein the video segment information includes the album to which the sub-video belongs, the number of the albums to which the sub-video belongs, and the playing time interval of the sub-video, and the related meta-information, such as the video segment information, is output in real time according to the sub-video by indexing the database.
