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 technology, watching video and film becomes one of the popular entertainment modes. In the prior art, the downloading of the video is completed by means of a content delivery network (Content Delivery Network, CDN), and the video CDN refers to a set of CDN systems capable of providing video streaming services, which generally include systems of storage, synchronization, source return, scheduling, video file parsing, and the like. The basic principle of the CDN is that various cache servers (CDN edge nodes) are widely adopted, the cache servers are distributed to areas or networks with relatively concentrated user accesses, when the user accesses a website, the global load technology is utilized to direct the user accesses to the cache servers which work normally and are closest to the user, and the cache servers directly respond to the user requests.
When a user watches a video at a client, the downloading of the video stream files adopts the following mode that after the client initiates a request, an analysis list of the video files is firstly obtained from a video file analysis server, and then the downloading is sequentially carried out according to the files in the list. When downloading each file, the client needs to make a request to the dispatcher once, and downloads the file according to the returned result of the dispatcher to the appointed CDN edge node. If the downloading request of the file reaches an edge node, the node stores the file, and the data is directly spit to the client; if the file is not stored, a downloading request of the file is required to be sent to an upstream node, the data is spit to a client after the data of the upstream node is received, the file is stored locally, and if the same file request is next time, the file is not required to be requested to the upstream node. If the upstream node also does not have this file, a request needs to be sent upstream of this upstream node. The links of the download request finally form a tree structure, the edge nodes are leaf nodes of the tree, and the back source nodes are intermediate nodes and root stores of the tree. This way of downloading files in tree hierarchy is called a back source, and most of the files that are popular can be sent to the whole network in this way.
However, when the file requested by the client is not stored in the edge node, a downloading request needs to be sent to the upstream node, which has the problems of long source return link and low source return speed, so that the user cannot acquire 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 that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended 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 other than those described herein, and persons skilled in the art will readily appreciate 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 is required to send a download request to the upstream node, then there is a problem that the source return link is longer, and the source return speed is slow. The inventors have also found that, typically, if a certain file is newly online or a relatively cool 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 larger, such as a high-code rate file, if the source is returned after the client requests, the waiting time of the user is longer, and the user experience is greatly reduced. Although various optimization means are available for the transmission technology of the back source at present, when a client requests to download a certain video file, the file still cannot be stored in an edge node, and a user cannot acquire the file in time. Therefore, the prior art cannot be combined with personal viewing habits of users, so that the users cannot acquire the wanted video files in time, and user experience is reduced.
Based on the above technical problems, the embodiments of the present application provide a method and an apparatus for obtaining a video, where a network address of a first video may be determined from video access data within a first preset period of time, and because the video access data is related to a viewing behavior of a user, the network address of the first video is also 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, and 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 the same video set, and the video set includes a plurality of videos whose video contents have a correlation, that is, the second video and the first video have a certain correlation, and because the network address of the first video is related to the viewing behavior of the user, the second video that has a correlation with the first video is also related to the viewing behavior of the user, and is likely to be viewed later by the user. Therefore, according to the embodiment of the application, the network address of the related second video can be determined according to the video watching behavior of the user, so that the video server downloads the second video in advance, and when the user needs to watch the second video, the video server can directly spit the second video to the user without returning the source through the upper node, so that the user can watch the video which the user wants to watch faster, the waiting time of the user is reduced, and the user experience is further optimized.
In the embodiment of the present application, referring to fig. 1, a schematic structural diagram of a video acquisition system provided in the embodiment of the present application includes an origin server, a video server and a client. The source server is used for providing video file resources for the video servers, the video servers form a tree structure, the source server is located at a root node of the tree structure, the video servers at leaf nodes are provided with the video file resources 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 the video files so that users 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 video watching behavior analysis service for the user; the system may further include a meta information server, or a meta information module is set in the video server, where the meta information server or the meta information module is used to store meta information of the video, where the meta information of the video includes an album to which the video belongs, a number of collections to which the video belongs, and a playing time interval, for example, the video belongs to a 6 th collection of a television play a, and the playing time interval is from 10 th minutes to 15 th minutes. The video server, the analysis server and the meta-information server may be placed in the same video room, but of course the meta-information server may also be placed 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 is sent through a video server which can be 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 file is not stored in the video server, the video server needs to acquire the video file from the video server located in the upstream node through the CDN system, and then send the video file to the client.
For easy understanding, a method and an apparatus for acquiring video according to embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 2, a flow chart of a video acquisition method according to an embodiment of the present application is applied to the above analysis server or the analysis module in the video server, and the method 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 each time the user accesses the video through the video server, the access log records the network address of the video. The access log may include a network address, access time, etc. of the accessed video, and the analysis server or the 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, for example, as that the first user accesses video one at 7 o' clock 10 time. 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 that the access log of the user is collected in real time. Thus, at least one accessed video may be determined from the video access data, the at least one accessed video being determined as a first video, the network address of the first video referring 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 (Uniform Resource Locator, URL).
In the embodiment of the present application, because of the limitation of the disk space of the video server, all accessed videos may not be determined as the first video, so S101 has various implementation manners. The first video may be determined according to the access time, specifically, the videos are ordered according to the access time, and the first N accessed videos are determined as the first video. The first video may also be selected randomly, and specifically, the network address of the first video may be determined randomly 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 access times, and referring to fig. 3, a flowchart of determining the first video provided in an embodiment of the present application is shown, 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 a user accesses the video, the access log records the video, so that the video access data comprises network addresses of a plurality of accessed videos accessed at least once. For example, the video server stores video one, video two, video three, video four and video five, in a preset period of time, the number of times of accessing video one is 100, the number of times of accessing video two is 120, the number of times of accessing video three is 115, the number of times of accessing video four is 200, and the number of times of accessing video five is 0, and then the video access data includes network addresses of video one, video two, video three and video four, and does not include network addresses of video five.
S1012, sequentially ordering the network addresses of the multiple accessed videos according to the access times from more to less.
In the embodiment of the application, one video server can be accessed by one user for multiple times or multiple times, so that the network address of a certain video can be accessed for multiple times. The more the video is accessed, the more the ranking position is. Thus, the more the number of accesses, the more people viewing the video, the higher the popularity of the video, and the closer the combination of the viewing behavior of the user. For example, the four accessed videos are respectively marked as a first video, a second video, a third video and a fourth video, the access times are respectively 100, 120, 115 and 200, and then the four videos are sequentially ordered according to the access times from more to less, and the ordering result is the fourth video, the second video, the third video and the first video.
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 application, due to the limitation of the disk space of the video server, the network addresses of the first N accessed videos can 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 application, the analysis server or the analysis module in the video server can acquire the performance index of the video server, such as the residual disk space. And positive correlation exists between the N and the residual disk space of the video server, and the larger the residual disk space is, the larger the N is. Specifically, if the remaining disk space of the video server is larger, a larger value can be taken for N, and the number of network addresses of the first video is larger; if the remaining disk space of the video server is smaller, the N may be a smaller value, and the number of network addresses of the first video is smaller.
S102, acquiring the network address of the 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 application, the second video and the first video belong to the same video set, and one video set comprises a plurality of videos with correlation to video contents. A video collection includes a plurality of videos, and the videos have a certain correlation, and may all belong to the same album, for example, the same movie or the same television play. Video information may be written into a database in the meta information server and an index service is 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 a video set to which the first video belongs.
In the embodiment of the application, an analysis server or a video server with an internal 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 comprises a network address of the first video; the meta information server or a meta information module in the video server determines a video set to which the first video belongs according to the network address of the first video, then acquires the 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; the analysis server or an analysis module in 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 using 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 locally (video server), so that the time that the user waits for downloading for a long time is avoided, and the user experience is improved.
In the embodiment of the present 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. If N is 5, then the 5 video sets to which the first video belongs can be determined according to the network addresses of the 5 first videos, and then the network addresses of the 5 second videos are obtained from the 5 video sets.
In the embodiment of the application, one or more videos can be determined for each first video. Specifically, each first video can determine a video, that is to say, a video, such as a second video, is obtained from a video set to which the first video belongs; each first video may also determine a plurality of videos, that is, a plurality of videos may be obtained from a video set to which the first video belongs, for example, two videos, a second video and a third video may be 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 2 videos are corresponding to each first video and are respectively recorded as a second video and a third video, the total number of the second video and the third video can be 10. Acquiring a network address of the second video and a network address of the 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 the 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 network addresses of the plurality of videos can be determined to 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 smaller, the number of the determined network addresses of the plurality of videos can take a smaller value.
In the embodiment of the present application, when N >1, since the plurality of first videos may belong to different video sets or albums, it may be determined which videos need to be preferentially selected for source retrieval according to the heat of the album. If the heat of the album to which the video belongs is higher, more people can watch the album, and more videos belonging to the album can be downloaded, so that the use experience of the user is improved.
In an embodiment of the application, the videos in the collection are videos from an album, which may include one or more target videos. Specifically, when the duration of the target videos in the album is short, all the target videos in the album can be combined into one video set, and the first video is the target video in the album, and at this time, one album is one video set. When the target video in the album is long in duration, the target video can be segmented, one target video is segmented 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 segmentation. For example, if the duration of the target video is longer than 6 minutes, slicing the target video, otherwise, not slicing.
In the embodiment of the application, if the duration of a single video in the album is longer, the video can be fragmented. One or more target videos may be included in an album, e.g., if the album is a movie, then the album may be considered to include one target video; multiple videos belonging to the same television play can be considered to belong to the same album, and then the album is considered to contain multiple target videos, and one television play is one target video. The slicing refers to dividing all target videos in an album into a plurality of sub-videos according to a playing sequence, and the duration of the sub-videos is not limited herein, for example, may be 6 minutes. The network address of each sub-video is a URL.
In the embodiment of the application, each sub-video needs to mark the start and stop positions of the time in the target video, namely, mark the playing time interval. If the album comprises a target video, marking the playing time interval of the sub video in the target video by the sub video; if the album includes a plurality of target videos, the sub-video needs to mark the target video to which the sub-video belongs, and also needs to mark the playing time interval of the sub-video in the target video to which the sub-video belongs.
