All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Currently, conventional NVR stores video on a local disk, however, if the local disk is destroyed, the video is permanently lost. It can be seen that how to provide a technical solution for avoiding the permanent loss of video caused by the local disk damage is a problem that needs to be solved by those skilled in the art. Therefore, the invention provides a video storage scheme which can avoid permanent loss of video caused by local disk damage.
The embodiment of the invention discloses a video storage method, which is shown in fig. 1 and is applied to a target cloud server, and comprises the following steps:
step S11: and receiving the target video stream pushed by the target video recording equipment.
In this embodiment, the target cloud server receives a target video stream pushed by the target video device. It should be noted that the target video recording device may push not only the real-time video stream to the target cloud service but also the historical video stream to the target cloud server.
In this embodiment, before receiving the target video stream pushed by the target video recording device, the method may further include: receiving a video request with a video requirement attribute sent by a client through a central scheduling server, and configuring a corresponding video task according to the video request; and the video recording task is issued to target video recording equipment through the central scheduling server, so that the target video recording equipment records video based on task attributes in video recording task configuration information, and simultaneously, the recorded target video stream is pushed to a target cloud server corresponding to the push server address in real time according to the push server address in the video recording task configuration information. It can be understood that the client sends a video request carrying a video requirement attribute to the central scheduling server, and then configures a corresponding video task according to the request through the central scheduling server, and sends the video task to the target video device, so that the target video device can record video according to the task attribute in the video task configuration information, and push the recorded video stream to the corresponding target cloud server in real time according to the push server address in the video task configuration information. Note that the client may be a PC (Personal Computer ) client, APP (Application) client, or Web (World Wide Web) client, and the target video recording device may be NVR or IPC (Internet Protocol Camera, web camera).
In this embodiment, the target video recording device records video according to the task attribute in the video recording task configuration information, and if the task attribute in the video recording task configuration information indicates that the video recording task is a periodic task, video recording is performed according to a preset video recording period; and if the task attribute in the video task configuration information indicates that the video task is an event task, video recording is carried out when a target event corresponding to the event task is detected. It can be understood that if the video recording request sent by the client is a request for event video recording, the target video recording device detects a target event and then performs video recording and pushes the target event to the target cloud server; if the video recording request sent by the client is a request for periodic video recording, video recording is carried out according to a preset video recording period, and the target cloud server automatically detects that the data storage reaches the target period and automatically clears the historical data.
In this embodiment, the method may further include: the target video equipment and the target cloud server are respectively numbered through the central scheduling server, so that a video equipment identification number corresponding to the target video equipment and a cloud server identification number corresponding to the target cloud server are obtained; and establishing an association relationship between the target video equipment and the target cloud server based on the video equipment identification number and the cloud server identification number through the central scheduling server, and storing the association relationship in a table form. It can be understood that when the target video recording device pushes the video stream to the target cloud server for the first time, the target video recording device and the target cloud server can be bound through the central scheduling server, specifically, the target video recording device and the target cloud server are numbered, an association relationship between the target video recording device and the target cloud server is established based on the number, and the association relationship is stored in a form of a table, so that when the subsequent target video recording device pushes the video stream, the corresponding target cloud server can be directly found from the table, and then the video stream is pushed to the target cloud server. That is, a table is stored in the central scheduling server, and a correspondence between the ID (Identity document, dedicated number) of the record ECS (Elastic Compute Service) and the ID of the video recording apparatus, that is, a relationship between the target cloud servers to which the target video recording apparatus corresponds is stored in the central scheduling server. It should be noted that one ECS may correspond to multiple video recorders, each with 1 or more channels, but one ECS may carry up to 150 channels.
Step S12: and performing equal-time long slicing on the target video stream to obtain a plurality of target video fragments with the same time length.
In this embodiment, the target video stream is sliced at equal time intervals according to a preset slicing rule, so as to obtain a plurality of target video segments with the same duration. Specifically, the target video stream is sliced at equal time intervals according to a preset video time length, so as to obtain a plurality of target video fragments with the same time length.
Step S13: and converting each target video segment into a corresponding video file to obtain a target video file corresponding to each target video segment.
In this embodiment, the target video stream is sliced at equal time intervals to obtain a plurality of target video segments with the same time duration, and then each target video segment is converted into a corresponding video file to obtain a target video file corresponding to each target video segment.
Step S14: storing the target video files corresponding to the target video clips into a local target disk, numbering the target video files, and obtaining video file identification numbers corresponding to the target video files.
In this embodiment, the target video file corresponding to each target video clip is stored in a local target disk, for example, a video stream pushed by a target video recording device is sliced, and each video clip is stored in the form of a video file in S3 (Simple Storage Service, a simple storage service) of a local amazon standard. It should be noted that the amazon standard S3 store is typically used to store fragmented files, such as music video material, and each file has a unique URL (Uniform Resource Locator ).
In this embodiment, the target video stream is sliced, then each target video clip is sequentially converted into target video files, and each target video file is numbered to obtain a video file identification number corresponding to each target video file. For example, RTSP (Real Time Streaming Protocol), real-time streaming protocol) video stream is sequentially converted into a bin file stored once every 30s, and the ID and the storing time of the converted bin file are automatically recorded. It can be understood that when a continuous video stream is cut into bin files with a preset short time and stored sequentially according to the storage time, and the video stream is stored in the cloud in a fragmentation form of the files with the preset short time, the storage is free from capacity limitation, and recording with infinite duration can be realized by expanding a cloud server.
Step S15: and establishing an association relation between the video recording time of each target video clip and the corresponding video recording file identification number, and establishing a corresponding target index table based on the association relation.
In this embodiment, an association relationship between the recording time of each target video clip and the corresponding recording file identification number is established, and a corresponding target index table is established based on the association relationship. It can be understood that the index table is built by the numbers, the index table is also used for the subsequent video playing process, so that a great amount of data loss caused by interruption or failure of the video stream in the storage or playing process is effectively avoided, the user experience is influenced, the noninductive playing is realized, namely, the Amazon S3 storage collocation index table is built into a set of service capable of supporting storage and reading, periodic and continuous data streams, and finally, the streaming monitoring data is supported to be stored in the Amazon S3 storage for 7x24 hours, and the noninductive viewing is supported.
It should be noted that, for different types of requirements, a corresponding index table of a target cloud server in the target cluster is determined, where the classification of the target cluster may be classified according to a cloud platform type or a target country type, and the cloud platform type may be amazon, ali cloud, or Hua cloud, and the like.
Therefore, in the embodiment of the invention, the video is prevented from being permanently lost due to the damage of the local disk of the target video equipment by performing the equal-time long slicing on the target video stream pushed by the target video equipment and storing the video clip in the local target disk of the target cloud server in the form of the video file, and the corresponding target index table is established, so that the corresponding relation between the video recording time and the video clip can be queried from the target index table when the video is played, and further the video playing can be performed from the appointed video recording starting time.
The embodiment of the invention discloses a video playing method, which is shown in fig. 2 and is applied to a central scheduling server, and comprises the following steps:
step S21: receiving a video reading request sent by a client; the video reading request is a request carrying video starting time or video starting and ending time and video equipment identification number.
In this embodiment, the client sends a video reading request to the central scheduling server, that is, the central scheduling server receives the video reading request sent by the client, where the video reading request is a request carrying a video start time or a video start-stop time and a video equipment identification number.
Step S22: and determining a target cloud server associated with the target video equipment corresponding to the video equipment identification number from a locally stored table according to the video equipment identification number carried in the video reading request.
In this embodiment, a table is stored in the central scheduling server, where a correspondence between an ID of the ECS and an ID of the video recording device is recorded, so that the central scheduling server determines, from the locally stored table, a target cloud server associated with a target video recording device corresponding to the video recording device identification number according to the video recording device identification number carried in the video reading request.
Step S23: and determining a target index table which is established by the target cloud server and corresponds to the target video equipment.
In this embodiment, after determining, from a locally stored table, a target cloud server associated with a target video device corresponding to the video device identification number according to the video device identification number carried in the video reading request, a target index table corresponding to the target video device and established by the target cloud server is determined.
Step S24: playing the corresponding target video file under the target index table based on the video start time or the video start-stop time carried in the video reading request; the target video file is stored in the target cloud server based on the video storage method disclosed by the prior art.
In this embodiment, when the video is stored, an association relationship between the video time of each target video clip and the corresponding video file identification number is established, and a corresponding target index table is established based on the association relationship, so after the target index table corresponding to the target video device is determined, the corresponding target video file under the target index table is played based on the video start time or the video start-stop time carried in the video reading request; the target video file is stored in the target cloud server based on the video storage method disclosed by the prior art.
In a specific embodiment, if the video start time is carried in the video read request, all the target video files are sequentially played according to the video file identification numbers corresponding to the video start time under the target index table and the identification number sequence. It can be understood that, when the video recording start time is only carried in the video recording request, all the bin files under the target index table corresponding to the target video recording device are sequentially played from the bin file corresponding to the video recording start time until the video stream is played.
In another specific embodiment, if the video start-stop time is carried in the video reading request, determining a video file identification number and the number of video files corresponding to the video start-stop time under the target index table based on the video start-stop time, and playing corresponding target video files according to the video file identification number and the number of video files. It can be understood that, reading the video start-stop time carried in the video request, that is, indicating that a video with a certain duration is to be played, determining the video file identification number and the video file number corresponding to the video start-stop time under the target index table based on the video start-stop time, and playing the corresponding target video file according to the video file identification number and the video file number until the video stream is played.
For example, the embodiment of the invention also discloses a cloud service framework with flexible, extensible and strong fault tolerance, as shown in fig. 3, a channel database and a central scheduling server are arranged in the scheduling group, record global task information and are responsible for issuing the task information to NVR equipment, wherein the NVR equipment supports configuration plug-flow tasks, and the tasks support periodic tasks and event tasks; the task configuration comprises attributes such as a task ID, a push server address, task parameters and the like, and the task also supports a deletion operation, namely, a central scheduling server in a scheduling Group receives a video request with a video requirement attribute sent by a client (a WEB page or an APP mobile terminal), then configures a corresponding video task according to the video request, and issues the video task to target video equipment through the central scheduling server, so that the target video equipment carries out video based on the task attribute in video task configuration information, simultaneously pushes the recorded target video stream to a target cloud server corresponding to the push server address according to the push server address in video task configuration information, further saves the video stream to an OSS (Object Storage Service ) storage, namely, the central scheduling server also selects push nodes (push servers) at the same time of configuring the video task, for example, cloud storage [ Group001 ] or cloud storage [ Group002 ], wherein each storage comprises a corresponding cloud storage table and an index stream index table corresponding to the cloud storage table, and the index table has an index table corresponding to the index table. It should be noted that, a table is stored in the central scheduling server, in which a correspondence between the ID of the ECS and the ID of the video recording device is recorded, that is, an association between the target cloud servers corresponding to the target video recording devices is stored in the central scheduling server, and one ECS may correspond to a plurality of video recording devices, each video recording device has 1 path or multiple paths, but one ECS may carry 150 paths at most.
The periodic task represents video recording all the time until the video recording time length reaches the configured length, and the video recording is covered in a follow-up cycle; the event task indicates that no video is recorded at ordinary times, and when some events occur at target time such as mobile detection, IO alarm and the like, video recording is started.
When the video stream of the NVR device is pushed to the push server, the push server uses gRPC technology to query the central scheduling server for task attributes, and informs the event to the video server in the same lan, and the video server takes FLV (flash format) address and the task attributes to start recording the video stream. For example, the video server first queries whether the task has been recorded, if so, the index database, finds the latest slice ID, and continues writing data from this slice; otherwise, writing data from the 0 th slice; each time slice data (video of about 30 s) is written, an index is written, which is accurate to each GOP (Group of Pictures ). The video server supports real-time video and historical video, the real-time video uses a physical timestamp as a starting timestamp, the historical video uses a ts_start value in ScriptData in an FLV header as a starting timestamp, the video server supports a video query function, a video viewing function is supported according to time period query and month query (see which days in a month are recorded), the video server firstly queries slice IDs from an index database according to starting time provided by a user, then GOP data corresponding to the slice IDs are read, then video streams in an FLV format are repackaged for the user to play, and when one GOP is read completely, the next GOP is read along. It should be noted that, the push server may receive video data from the NVR, and use the FLV address to distribute the video data to play the video data to the user, where the video server and the push server are in the same cloud lan, and are used to pull the video record from the FLV provided by the push server, and store the video record in S3, where the data source represents the data source of the monitoring data, and is generally the lan FLV address provided by the push server in the cloud lan.
