The video cloud storage system is generally composed of an index server, a storage server and a client. Specifically, there are generally a plurality of storage servers for storing video data. The index server is used for storing index information of the video data, the index information is a corresponding relation between attribute information of the video data and a storage server identifier, wherein the attribute information comprises a monitoring point identifier and a time range of the video data, and the storage server identifier is an identifier of a storage server storing the video data. For a surveillance video, the monitoring point identifier is generally an identifier of a monitoring device corresponding to the surveillance video, and for other videos, the monitoring point identifier may be a virtual monitoring point identifier, for example, an obtaining device identifier, a type identifier, and the like corresponding to video data. The client can write, download and playback videos.
When a user utilizes a client to carry out ordinary video playback, the user inputs a monitoring point identifier through the client and selects a playback time range of a video, the client initiates an inquiry request carrying the monitoring point identifier and the playback time range to an index server, the index server inquires a corresponding storage server identifier from index information and returns the storage server identifier to the client, the client further sends a playback request carrying the monitoring point identifier and the playback time range to the storage server corresponding to the storage server identifier, the storage server returns video data of the playback time range of a monitoring point corresponding to the monitoring point identifier to the client after receiving the playback request, and the client receives the video data sent by the storage server and decodes and plays the video data. If the video data in the playback time range are divided into multiple segments of video data and stored in different storage servers, the client requests the multiple storage servers for the video data according to the playing time sequence according to the multiple storage server identifiers and the corresponding time range identifiers of the video data inquired by the index server, that is, when the first segment of video data is received, the client requests the storage server storing the second segment of video data for the second segment of video data, and so on until all the video data are received.
In the ordinary playback process, a user often selects forward or backward jump-playing videos, namely positioning playback, at the moment, a client sends a positioning time point input by the user to a corresponding storage server, the storage server stores video data with a time range including the positioning time point, the storage server returns the video data starting from the positioning time point to the client, and the client decodes and plays the video data until the end time point of the playback time range is played or the user stops playback or performs positioning playback again.
Therefore, the client needs to request the storage server for video data every time when the video is positioned and played back, and needs to request the same video segment for multiple times when a user repeatedly watches the same video segment.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to reduce the time delay of video positioning playback and improve the efficiency of video positioning playback, the embodiment of the invention provides a video positioning playback method and device based on a video cloud storage system.
First, a first video positioning playback method based on a video cloud storage system according to an embodiment of the present invention is described below.
First, it should be noted that the method provided by the embodiment of the present invention is based on a video cloud storage system, where the cloud storage system includes a plurality of storage servers, and each storage server stores video data. The method can be applied to a client, an information table is recorded in the client, and the information table comprises the one-to-one correspondence relation among the file identification, the monitoring point identification and the time range of the video data locally cached by the client.
As shown in fig. 1, a video positioning playback method based on a video cloud storage system is applied to a client, and the method includes the following steps:
s101, obtaining a positioning time point input by a user;
in the ordinary playback process, when a user needs to play back a certain section of video in a positioning mode, a positioning time point is input at a client in a mode of dragging a video progress bar and the like, and the client can obtain the positioning time point. The positioning time point is a starting time point at which the user wants to position the playback video, for example, the user is watching a monitoring video from 8 am to 9 am, and when watching the monitoring video to 8 am, 40 minutes, the user drags the video progress bar to 8 am, 30 minutes, and repeatedly watches, so that the client can obtain the positioning time point, i.e. 8 am, 30 minutes.
S102, determining a target monitoring point identifier corresponding to the positioning playback;
when the user performs ordinary playback of the video, the client inputs the monitoring point identification of the video data to be played back, so that the client can request the corresponding video data from the video cloud storage system, and the target monitoring point identification is the monitoring point identification which is recorded by the client during ordinary playback and is input by the user.
S103, searching a first file identifier which simultaneously meets a first condition and a second condition from the information table by using the positioning time point and the target monitoring point identifier;
wherein the first condition is: the corresponding monitoring point identifier is matched with the target monitoring point identifier, and the second condition is as follows: the corresponding time range comprises the positioning time point. It should be noted that matching the monitor point identifier corresponding to the first file identifier with the target monitor point identifier may be: the monitor point identifier corresponding to the first file identifier is the same as the target monitor point identifier, or a corresponding relationship between the monitor point identifier corresponding to the first file identifier and the target monitor point identifier may be preset, for example, if the target monitor point identifier is 096, then 096a may be set as the monitor point identifier matching the target monitor point identifier 096.
In the history positioning playback process, the client can store the video data acquired from the first storage server of the video cloud storage system to the local as the cached video data. In order to facilitate quick search of the cached video data during subsequent positioning playback and improve the video positioning playback efficiency, the client can construct an information table, and record the one-to-one correspondence relationship among the file identifier, the monitoring point identifier and the time range of each cached video data in the information table. It can be understood that the monitor point identifier of each cached video data is a monitor point identifier that matches with a corresponding target monitor point identifier input by a user during normal playback, and is used to represent attributes such as a source or a type of the video data. The client may store the information table in a database for searching, for example, the information table may be stored in a database such as SQL (Structured Query Language), which is not limited in this respect.
Therefore, after the client obtains the positioning time point, the client can quickly search the file identifier recorded in the information table for the corresponding monitoring point identifier to be matched with the target monitoring point identifier by using the positioning time point and the recorded target monitoring point identifier, and the time range comprises the first file identifier of the positioning time point, so as to determine whether the video data of which the time range comprises the positioning time point is cached locally.
In general, the time range of the video data cached locally by the client may be represented by or include a start time point and an end time point of the segment of video data. Thus, the client can determine whether the time range of the video data contains the positioning time point according to the time range of the video data.
For example, if the positioning time point is 8 o' clock and 30 minutes, the time range of a certain segment of buffered video data is: start time point: 8 point, 25 minutes, duration: 600 seconds, the time range of the buffered video data is 8 o ' clock 25 minutes to 8 o ' clock 35 minutes, which obviously includes 8 o ' clock 30 minutes. If the duration of the buffered video data is 200 seconds, the time range of the buffered video data is 8 o ' clock 25 minutes to 8 o ' clock 28 minutes 20 seconds, and obviously the positioning time point 8 o ' clock 30 minutes is not included. Therefore, through the time range of the cached video data, the client can quickly and accurately determine whether the time range of the cached video data contains the positioning time point.
Of course, the time range of the video data locally cached at the client may also be identification information that can represent the time range of the piece of cached video data, which is determined according to other information, and is not specifically limited herein.
It should be noted that, in order to ensure the uniqueness of the file identifier of the cached video data, no repeated file identifier occurs, so as to ensure the search speed and avoid the search error, the file identifier is generally determined based on the corresponding time range, for example, a hash algorithm value corresponding to the start time point of the video data may be used as the file identifier of the video data. Of course, the file identifier of the video data may also be determined in other manners, as long as the uniqueness of the file identifier can be ensured, and is not specifically limited herein.
For example, the information table may adopt the following information table:
| file identification | Monitoring point identification | Starting point in time | Time length (second) |
| 277faed0e94b44ff598f74b081284a1f | Cam_a | 2016-06-21 09:00:00 | 118 |
| 6641313271e1684213dc56b398e756b5 | Cam_b | 2016-06-21 09:11:01 | 201 |
| … | … | … | … |
In the information table, the file identifier of each segment of cached video data is the hash algorithm value corresponding to the start time point of the segment of video data.
S104, if the first video data corresponding to the first file identification is found, acquiring first video data corresponding to the first file identification;
the first video data are locally cached video data which are obtained from a first storage server in the history positioning playback process by a client, and the first storage server is a storage server in a video cloud storage system inquired in the history positioning playback process.
When the first file identifier is found, the client locally stores the video data with the time range including the positioning time point, namely the first video data. The client can then find the first video data according to the first file identifier.
In order to conveniently query the first video data, the file identifier of each segment of cached video data can be used as the file name of the segment of cached video data, so that after the client finds the first file identifier, the client can find the first video data with the same file name as the first file identifier, which is very convenient. Of course, the client may also use a manner of associating the file identifier of each segment of cached video data with the segment of video data in a one-to-one correspondence manner, as long as the purpose of finding the first video data through the first file identifier can be achieved, and the method is not particularly limited herein.
And S105, starting to play the first video data from the positioning time point.
After the first video data is obtained, the first video data can be played from the positioning time point, and the user can watch the video which is desired to be played back until the user stops playing the video or performs next positioning playback or the playing of the first video data is finished.
As an implementation manner of the embodiment of the present invention, a manner of starting playing the first video data from the positioning time point may include:
analyzing image frame data of the first video data to obtain a corresponding relation between a time point and an image frame; searching the image frame corresponding to the positioning time point according to the corresponding relation; and starting to play the target cache video file from the searched image frame.
After the client finds the first video data, the client can analyze the image frame data of the first video data to obtain the time point corresponding to each frame image, and further can determine the image frame corresponding to the positioning time point, and then start to play the first video data from the image frame corresponding to the positioning time point.
It should be noted that, the above image frame data analysis is a common image data processing method in the art, any conventional image frame data analysis method may be adopted, and those skilled in the art may determine the method according to factors such as the type of video data, and the method is not specifically limited and described herein.
It can be seen that, in the scheme provided in the embodiment of the present invention, the client first obtains the positioning time point input by the user, determines the target monitoring point identifier corresponding to the current positioning playback, then searches for the first file identifier satisfying the first condition and the second condition from the information table by using the positioning time point and the target monitoring point identifier, and when the first file identifier is found, obtains the first video data corresponding to the first file identifier, and starts to play the first video data from the positioning time point. Because the client can search and play the locally cached video data during the positioning playback of the video, the client does not need to request the storage server for the video data during each positioning playback, thereby greatly reducing the time delay of the positioning playback of the video and improving the efficiency of the positioning playback of the video.
As an implementation manner of the embodiment of the present invention, if the first file identifier is not found, the method may further include:
sending the positioning time point and the target monitoring point identification to the cloud storage system;
and receiving and playing second video data from a first storage server of the cloud storage system, wherein the second video data is the video data of which the monitoring point identification inquired by the first storage server is matched with the target monitoring point identification and the time range comprises the positioning time point.
When the client does not find the first file identifier, it indicates that there is no video data meeting the positioning playback requirement in the locally cached video data, that is, there is no video data with a monitoring point identifier matching the target monitoring point identifier in the locally cached video data, and the time range includes the video data of the positioning time point. At this time, the client may send the positioning time point and the target monitoring point identifier to the cloud storage system to request the video data to be played.
In an implementation manner, the cloud storage system comprises an index server and a plurality of storage servers, a client sends a positioning time point and a target monitoring point identifier to the index server, the index server feeds back a first storage server identifier which stores the video data of which the monitoring point identifier is matched with the target monitoring point identifier and the time range comprises the positioning time point to the client according to the corresponding relation between the monitoring point identifier, the time range and the storage server identifier of the stored video data, and then the client can send the positioning time point and the target monitoring point identifier to the first storage server to request the corresponding video data.
In another embodiment, the cloud storage system comprises a plurality of storage servers, each storage server stores an index table, and the index table records the corresponding relationship between the monitoring point identifier, the time range and the storage server identifier of the video data. The client sends the positioning time point and the target monitoring point identification to any storage server, the storage server inquires a first storage server identification which stores the video data of the monitoring point identification matched with the target monitoring point identification and with the time range including the positioning time point according to the stored index table, and feeds the first storage server identification back to the client, and then the client can send the positioning time point and the target monitoring point identification to the first storage server to request corresponding video data.
Then, after receiving the positioning time point and the target monitoring point identifier sent by the client, the queried first storage server may send second video data from the positioning time point to the end of the current video to the client. Further, the client can receive and play the second video data for the user to watch.
It can be understood that, if the user stops playing the video or performs positioning playback again or reaches the end time point corresponding to the time range input by the user during the process that the first storage server transmits the second video data from the positioning time point to the end of the video to the client, the first storage server stops transmitting the video data, that is, the second video data is the video data already transmitted to the client.
As an implementation manner of the embodiment of the present invention, while receiving the second video data, the client may locally cache the video data of the second video data from the starting time point to the first preset time duration, that is, the third video data, store the monitoring point identifier of the third video data in the information table, and correspondingly store the time range and the file identifier of the third video data, so that when performing subsequent positioning playback, the client may play the locally cached third video data under the condition that the positioning playback requirement is met, and reduce the time delay of the positioning playback of the video.
It should be noted that, since the duration of the second video data is generally longer, for example, 10 minutes, 20 minutes, and the like, if the second video data is completely cached locally at the client, a larger memory is required to be occupied, and the working efficiency of the client is reduced, only a part of the video data from the start time point of the second video data is generally cached, that is, the video data within the first preset duration. The first preset time duration is not greater than the time duration of the second video data, and may be generally 10 seconds, 30 seconds, 50 seconds, and the like.
In order to facilitate searching for the locally cached video data during subsequent positioning playback, the client may store the monitoring point identifier of the third video data in the information table, and correspondingly store the time range and the file identifier of the third video data. It can be understood that the monitor point identifier of the third video data may be the same as the monitor point identifier of the second video data, that is, matched with the target monitor point identifier input by the user during the current normal playback. Since the determination method of the time range and the file identifier has been described in detail in the above step S103 and step 104, the relevant parts can be referred to the partial description in the above step S103 and step 104, and are not described again here.
After the monitor point identifier, the time range, and the file identifier of the third video data are determined, the monitor point identifier, the time range, and the file identifier may be recorded in the information table, so as to query the first file identifier during subsequent positioning playback.
As an implementation manner of the embodiment of the present invention, in order to further improve the video positioning playback efficiency and reduce the time delay, while playing the first video data, as shown in fig. 2, the method may further include the following steps:
s201, obtaining a playing completion time point;
wherein, the playing finish time point is the finish time point of the first video data. It can be understood that, when the client plays the first video data, the end time point of the first video, that is, the play-completed time point, can be obtained according to the time range of the first video data recorded in the information table. For example, if the time range of the first video data is: start time point: 11 point, 10 minutes, duration: 60 seconds, the playing completion time point of the first video is 11 points and 11 minutes.
S202, judging whether the playing finishing time point is earlier than a target finishing time point, if so, executing a step S203, otherwise, executing a step S204;
when the user performs the normal playback of the video, the time range of the normal playback, that is, the start time point and the end time point of the normal playback video data, is input at the client, and the target end time point is the end time point recorded by the client and input by the user during the normal playback.
If the client determines that the playing completion time point is earlier than the target end time point, which indicates that the end time point input by the user during the ordinary playback is not reached when the first video data is played, and the video data that the user wants to watch is not played back, the client may request the video cloud storage system for the subsequent video data of the first video data, and the client may continue to execute step S203.
S203, searching a second file identifier which simultaneously meets a third condition and a fourth condition from the information table by using the playing completion time point and the target monitoring point identifier, if the second file identifier is searched, executing the step S205, and if the second file identifier is not searched, executing the step S206;
wherein the third condition is: the corresponding monitoring point identification is matched with the target monitoring point identification, and the fourth condition is as follows: the corresponding time range comprises the playing finishing time point.
The playing completion time point is earlier than the target ending time point, and the client needs to continue playing subsequent video data, so that in order to reduce the frequency of requesting video data from the first storage server as much as possible and reduce the time delay, the client can inquire whether video data capable of being continuously played exists in other locally cached video data, that is, the monitoring point identifier is matched with the target monitoring point identifier, and the time range includes the video data of the ending time point of the first video data. Then, the playing completion time point and the target monitoring point identifier may be utilized to search for the second file identifier satisfying the third condition and the fourth condition from the information table, and the manner of querying the second file identifier is similar to the manner of searching for the first file identifier, and the relevant points may be referred to the description of the manner of searching for the first file identifier, which is not repeated herein.
S204, continuing to play the first video data to the target ending time point;
if the client judges that the playing finishing time point is not earlier than the target finishing time point, if the playing finishing time point is the same as the target finishing time point, the video data which all users want to watch is just played back when the first video data is played. If the playing completion time point is later than the target ending time point, which indicates that the first video data is not played completely, the ending time point input by the user in the ordinary playback process is already reached, and then the next video data does not need to be requested from the video cloud storage system. At this time, the first video data is continuously played until the target ending time point.
S205, when the first video data is played, acquiring fourth video data corresponding to the second file identifier, and starting to play the fourth video data from the playing completion time point;
when the second file identifier is found, the client side is explained to locally cache other video data including the ending time point of the first video data, the client side does not need to request the first storage server for the video data, then when the first video data is played, the fourth video data corresponding to the second file identifier can be obtained, and then the fourth video data is directly played from the playing ending time point, so that the time delay of positioning playback is further reduced, and the efficiency of positioning playback is improved. The fourth video data is the video data acquired from the first storage server in the history positioning playback process of the local cache.
Since the manner of playing the fourth video data from the playing-finished time point is similar to the manner of playing the first video data from the positioning time point, reference may be made to the description of the manner of playing the first video data from the positioning time point, and details are not repeated here.
S206, sending the playing completion time point and the target monitoring point identifier to the cloud storage system;
when the second file identifier is not found, it is indicated that the client does not locally cache other video data including the playing completion time point, that is, there is no video data meeting the continuous playing requirement in the locally cached video data. At this time, the client may send the play completion time point and the target monitoring point identifier to the cloud storage system, so as to obtain video data that can be continuously played.
S207, receiving fifth video data from a first storage server of the cloud storage system, and playing the fifth video data when the first video data is played;
and the fifth video data is the video data of which the monitoring point identification inquired by the first storage server is matched with the target monitoring point identification and the time range comprises the playing completion time point. After receiving the fifth video data, the client can continue to play the fifth video data for the user to continue watching when the first video data is played.
It should be noted that a manner of acquiring the fifth video data from the cloud storage system by the client is similar to that of acquiring the second video data from the cloud storage system by the client, and for relevant points, reference may be made to partial description of the manner of acquiring the second video data from the cloud storage system by the client, and details are not repeated here.
S208, storing the sixth video data in a local cache;
and the sixth video data is video data from the starting time point of the fifth video data to a second preset time length. When receiving the fifth video data, the client may also buffer the video data from the start time point to a second preset duration, that is, the sixth video data, so that when performing subsequent positioning playback, the client may play the sixth video data under the condition that the requirement is met, so as to reduce the time delay of the video positioning playback. The second preset time duration is not longer than the time duration of the fifth video data, and may generally be 10 seconds, 20 seconds, 30 seconds, and the like.
S209, storing the monitoring point identifier of the sixth video data into the information table, and correspondingly storing the time range and the file identifier of the sixth video data.
In order to facilitate searching for cached video data during subsequent positioning playback, the client may record the monitoring point identifier of the sixth video data in the information table, and correspondingly store the time range and the file identifier of the sixth video data, so that the video data that can be played can be quickly queried during subsequent positioning playback.
For the caching mode of the sixth video data, the mode of determining the monitor point identifier, the time range and the file identifier of the sixth video data, and the mode of recording the monitor point identifier, the time range and the file identifier, because the detailed description is given in the description of the third video data, relevant parts can refer to the above description of the third video data, and are not repeated here.
It should be noted that, in order to further reduce the time delay of the positioning playback of the video and improve the efficiency of the positioning playback, while the second video data is played, the method may also include steps corresponding to the above step S201 to step S209, since these steps are similar to the above step S201 to step S209, the relevant points may be referred to the partial description of step S201 to step S209, and detailed description is omitted here.
