[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] See also Figure 1 As shown, the embodiment of the present application discloses a video storage method, including:

[0049] Step S11: Utilize the local disk of the network video recorder device to store the recorded video.

[0050] In this embodiment, the user can deploy cameras in multiple areas according to needs. In this embodiment, the NVR device can be used to receive the digital video stream of the camera through the network and use the local disk to store the recorded video.

[0051] In an optional implementation, a user's local video viewing request can be obtained based on a user interaction interface of a preset business system, and the preset business system can send a request to query the current recording status of the NVR device to the device streaming system, and the device streaming system returns the corresponding streaming address, and the preset business system plays back the video based on the streaming address. Among them, the corresponding streaming address can be obtained based on the time point of the video recording to play back the video. The preset business system can be a software system designed based on the business.

[0052] Step S12: Obtain user configuration information, wherein the user configuration information includes first configuration information and second configuration information, the first configuration information is used to determine the target video data to be uploaded to the cloud storage, and the second configuration information is used to determine the target video segment to be transferred.

[0053] In this embodiment, configuration information can be obtained based on the user interaction interface of the preset business system. The first configuration information may include target area information, such as cashier area information. In an optional implementation, the first configuration information may also include time period information, such as working hours (8 am to 8 pm). The second configuration information may include target event information, such as cashier abnormal events, which may include cash private collection events.

[0054] Step S13: Generate a cloud storage task based on the first configuration information and generate a segment transfer task based on the second configuration information.

[0055] It can be understood that the cloud storage task is a task of uploading the target video data corresponding to the first configuration information to the cloud storage. The segment transfer task is a task of transferring the target video segment corresponding to the second configuration information.

[0056] Step S14: Execute the cloud storage task, determine the target video data from the recorded video, and upload the target video data to the cloud storage.

[0057] In this embodiment, the cloud storage task can be executed, the video data corresponding to the target area information can be determined from the recorded video to obtain the target video data, and the target video data can be uploaded to the cloud storage. In an optional implementation, the target time period can be determined based on the time period information in the first configuration information, and the video data corresponding to the target area information in the target time period can be determined as the target video data. For example, the video data of the cashier area from 8 am to 8 pm is used as the target video data. In this way, uploading important data that users are concerned about to the cloud storage can obtain longer-term storage, avoid deleting important data when the local disk is full and overwritten, and meet long-term storage needs without increasing the high cost of local disk expansion.

[0058] In an optional implementation, the cloud storage task can be sent to the NVR device by using a preset device management system and a MQTT (Message Queuing Telemetry Transport) long link maintained between the preset device management system and the NVR device; the cloud storage task is recorded by the NVR device; accordingly, the cloud storage task is executed, the target video data is determined from the recorded video, and the target video data is uploaded to the cloud storage, including: executing the cloud storage task by the NVR device, determining the target video data from the recorded video, and uploading the target video data to the cloud storage. MQTT is a lightweight publish / subscribe message transmission protocol. MQTT long connection means that after the two parties establish a connection, the connection will remain open to facilitate the continuous transmission of messages until the connection is explicitly disconnected. Compared with short connections (disconnecting after each data transmission), long connections can reduce the additional overhead caused by connection establishment and closing, and improve data transmission efficiency.

[0059] In an optional implementation, the target video data can be streamed to a streaming S3 storage (i.e., cloud storage), and the file name organization format is two types, SDP class ( / uuid / v2 / Date / DayIndex / Timestamp-0-sdp), BLK class ( / uuid / v2 / Date / DayIndex / Timestamp-SeekStep-blk). SDP (i.e., Session Description Protocol) describes the information data of the stream, and BLK is the real video. SDP binary format: a complete SDP string in the channel stream information RTSP (i.e., Real Time Streaming Protocol) in the NVR; BLK binary format: a set of RTP packets encapsulated in interleaved frames in RTSP Over TCP (i.e., a streaming media transmission method that uses TCP connections to transmit RTSP control commands and RTP (i.e., Real-time Transport Protocol) / RTCP media data), 5000 RTP packets form a group to form a BLK. Wireshark analysis shows that the utilization of raw frame data encapsulated using RTP is reduced by about 1.3%, which meets the requirements. Although the utilization of raw data is slightly sacrificed, a variety of video storage methods are provided, and the video storage cost and video storage time can be balanced, which not only meets the personalized needs of users but also reduces costs and increases efficiency.

[0060] Step S15: Execute the segment transfer task to transfer the target video segment in the cloud storage or the local disk according to a preset format so that it can be played on each terminal device.

[0061] In this embodiment, the clip transfer task can be executed to transfer the target video clip corresponding to the target event information in the cloud storage or the local disk according to a preset format so that it can be played on each terminal device. For example, the video clip corresponding to the cash private collection event is transferred according to a preset format, and the preset format can be understood as a format that can be played on the terminal device. The terminal device includes a mobile terminal and a personal laptop computer, etc. The transferred video address can be shared. In some embodiments, the second configuration information can also include time period information.

[0062] In an optional implementation, the segment transfer task can be added to the task queue through the scheduling center, and the segment transfer task in the task queue can be consumed by a preset working node to transfer the target video segment in the cloud storage or the local disk according to a preset format. The preset working node can be understood as a software component that realizes the functional logic of consuming the segment transfer task in the task queue and transferring the target video segment in the cloud storage or the local disk according to a preset format, and can also be understood as a hardware device running the software component.

[0063] In an optional implementation, a preset working node may be used to consume the segment transfer task in the task queue, obtain a streaming address corresponding to the target video segment, and transfer the target video segment in a preset format based on the streaming address.

[0064] Furthermore, in an optional implementation, after the target video clip in the cloud storage or the local disk is transferred according to a preset format, the embodiment of the present application may also put the response information corresponding to the clip transfer task into a feedback queue, wherein the response message includes information indicating a successful transfer or a failed transfer; the response information in the feedback queue is consumed by the dispatch center, and when the response information includes information indicating a failed transfer, and the number of failed transfers corresponding to the clip transfer task does not reach a preset threshold, the clip transfer task is put into the task queue again. That is, this embodiment can make multiple attempts for a clip transfer task that failed to transfer.

[0065] When the response information includes information indicating successful transfer, in the embodiment of the present application, the response information may also include the address of the target video segment after transfer, and the user may view the target video segment based on the address through the terminal device.

[0066] It can be seen that in addition to using the local disk of the NVR device to store recorded videos, the embodiments of the present application can also store the target video data in the cloud based on the user configuration information and transfer the target video clips in a preset format to support playback on various terminal devices. In this way, not only can the local disk of the NVR device fully store recorded videos, but the target video data that users need to store for a longer period of time can also be stored in the cloud without expanding the local storage capacity, thereby reducing costs. In addition, the target video clips that need to be viewed in particular can be transferred to facilitate viewing and sharing on the terminal device. Through this application, the multi-dimensional needs of users can be met.

[0067] For further information, see Figure 2 As shown, Figure 2A specific video storage diagram provided for the embodiment of the present application. It includes three storage methods: Storage method 1 - NVR clip transfer (that is, the storage process corresponding to the aforementioned clip transfer task); Storage method 2 - NVR cloud storage (that is, the storage process corresponding to the aforementioned cloud storage); Storage method 3: NVR local disk streaming (that is, the storage process corresponding to the aforementioned local disk storage). Among them:

[0068] Storage method 1 - NVR clip transfer, including the following steps:

[0069] Step 101: The user configures the video transfer task through the business system, and the business system sends the transfer task to the transfer scheduling center. The transfer scheduling center first records the transfer task to its own database and assembles the transfer task into the task queue so that the nodes of the Worker group can consume the transfer task in the task queue. Among them, the transfer task can contain the basic information of a clip, such as: device MAC address, start time and end time of saving the video.

[0070] In step 102, the Worker node (i.e., the aforementioned working node) first obtains the streaming address from the device streaming media system (the streaming address may be in FLV, RTSP, or RTMP format depending on the device model), and the Worker node stores the streaming address locally, then calls the GPU transcoding module for transcoding, and finally transfers the transcoded video to the fragment S3 storage pool. After that, the Worker assembles the response message of the transfer task (such as transfer success or transfer failure), and puts the response message into the feedback queue. It should be pointed out that the encoding of some video recorders is H265, which is not particularly friendly to the player, so it is converted to H264. In terms of packaging, M3U8 is more friendly to the mobile terminal, and MP4 is more friendly to the PC terminal, so if you want to transcode, you can transcode it to MP4, FLV, and M3U8. In addition, in this embodiment, both cloud storage and fragment transfer can use the S3 storage pool, but the storage format of fragment transfer is different from that of video cloud storage.

[0071] Among them, the streaming address is obtained by communicating with the device streaming media system, and the device streaming media system is responsible for issuing device instructions and forwarding streaming media data. In the embodiment of the present application, the device streaming media system includes an MMS node (i.e., Media Management System) and a DMS node (i.e., Device Management System), wherein the MMS system is responsible for retrieving the video data stream in the local disk from the NVR device; the DMS system is responsible for communicating with the NVR device and forwarding instructions to the NVR device. If the transfer task is a video recording of private cash collection by a certain NVR device in the first target time period, the information of the target video clip (such as the start and end of the first target time period) is sent to the MMS node through the corresponding working node of the transfer task, and the MMS node communicates with the NVR device through the DMS node, obtains the streaming address of the first target time period corresponding to the corresponding NVR device, and then sends it to the working node that executes the transfer task. The information of the target video clip sent to the MMS node by the working node of the transfer task can also include the MAC address, channel, etc. of the NVR device. That is, the information sent to the MMS is the necessary information for requesting recording, such as the MAC address, channel, time point, etc. of the NVR.

[0072] Step 103, the dispatch center obtains the consumption response message from the feedback queue and uses a callback to notify the business system that the transfer task is completed. If the transfer fails due to other reasons, the dispatch center will save the corresponding transfer task in the database and try 6 times in the next 3 hours. If it still fails, the transfer task will be abandoned and the final result will be reported. Among them, the callback can be understood as an HTTP interface provided by the business system, and the worker calls the HTTP interface after completing the task.

[0073] Furthermore, when the NVR clips transferred by the embodiment are transferred successfully, the service system will obtain the CDN address of the clips after the transfer (that is, the storage address of the transferred clips), and the formats support MP4, FLV and M3U8, which basically support playback on all terminal devices. Users can view and play the target clips through the service system.

[0074] Storage method 2 - NVR cloud storage: The business system sends the command to start NVR cloud storage to the DMS node. The DMS node uses the MQTT long link maintained with the device to send the command to the NVR device. The command carries the cloud storage task. The NVR device records the cloud storage task and performs the NVR cloud storage task when it is in the effective time period of the cloud storage task. The video is streamed to the streaming S3 storage. The file name organization format is two types, SDP type ( / uuid / v2 / Date / DayIndex / Timestamp-0-sdp) and BLK type ( / uuid / v2 / Date / DayIndex / Timestamp-SeekStep-blk). For example, the effective time period can be from 8 am to 8 pm or all day. That is, cloud storage supports all-day storage, and can also be configured to store from 8 am to 8 pm.

[0075] Storage method 3 - NVR local disk streaming: The business system queries the device streaming system (MMS node) for the current recording status of the NVR device. At the time when the recording exists, the streaming address can be obtained from the device streaming system (MMS node) for recording playback.

[0076] Among them, storage mode 1, the transfer format is MP4, FLV or M3U8; storage mode 2, storage is SDP&BLK format; storage mode 3: can be directly extracted and played without transfer. In this embodiment, the video is stored in a hierarchical manner, and the video storage cost and video storage time are balanced to achieve cost reduction and efficiency improvement, and meet the multi-dimensional user needs.

[0077] This embodiment can divide the video storage into three levels for mixed storage according to the importance of the video in different time periods and the subjective choice of the terminal user, thereby reducing the storage cost. NVR cloud storage has high storage cost (cloud object storage), can be cyclically overwritten, and the storage time can be theoretically infinite, supporting event storage. Cyclic overwriting storage means presetting the storage time, and overwriting after the storage time. A relatively long storage time can be set, such as 1 year, 2 years, and 3 years. Event storage in cloud storage is an extended function. When cloud storage does not need to be stored all day, event cloud storage can be selected, which does not conflict with fragment storage. The difference is that cloud storage supports cyclic overwriting, and fragment transfer is a video file in sections, with an independent storage period strategy. The events for fragment transfer include: motion detection, smoking detection, flame detection, crowd detection, mobile phone detection, intrusion detection, smoke detection, etc. NVR local disk storage has low storage cost, and the storage time depends on the size of the local disk and the number of channels, and cyclic overwriting. Clip transfer: You can select clips from the local disk and NVR cloud storage for transfer. It can be stored permanently (you can also configure policy cleanup, such as when a user manually deletes a clip, it is also called policy deletion). It is low-cost and can be shared (static link).

[0078] Since NVR cloud storage is relatively expensive, it is suitable for scenarios that require long-term storage and high security. NVR local disk storage has low cost but limited storage time. If you want to extend the storage time, you need to expand the hardware capacity, which is costly. However, the fragment transfer recording is discontinuous, the recording fragment is short, the storage cost is very low, and the storage time is very long. This embodiment uses fragment transfer for important recordings (in actual applications, the captured events are usually stored, such as cashier anomalies / private collection events, preset alarm event capture and storage), low cost, long storage time, and convenient sharing. For example, the clip duration is about 5 minutes. Special recordings can use NVR cloud storage, which supports ultra-long storage, and the storage environment is safe. It is a safe storage method (in actual applications, it is usually the storage of long-term shooting content in store target areas such as cashier areas during working hours). General recordings use NVR local disk storage, and the cost and storage capacity are relatively balanced (comprehensive storage of daily store videos for users to back up and view).

[0079] The technical means adopted in this embodiment include video encapsulation formats RTSP, RTMP, FLV, MP4, AWS-S3 object storage, streaming protocols RTSP, RTMP, RTP (NVR cloud storage, the upload part requires object storage and streaming protocols), transport layer protocols TCP, KCP, FFmpeg, Nvidia encoder and decoder, message queue. It needs to be combined with other subsystems to run, mainly including: Network Video Recorder (Network Video Recorder is the storage and forwarding part of the network video surveillance system. NVR works with video encoder or network camera to complete the video recording, storage and forwarding functions). Device streaming media system, responsible for device command issuance and streaming media data forwarding. MMS system (responsible for retrieving video data streams from local disks from NVR devices); DMS system (responsible for communicating with NVR devices and forwarding commands to NVR devices).

[0080] Facing the multi-dimensional needs of users, such as: 1. The video clips of subjective concern are very small or multiple, and they need to be stored permanently; 2. There is a high requirement for integrity, and some regulations require a specified recording time (usually in years) and storage in a specified location (private data center). For the first case, the video can be segmented and the target segment can be stored in the cloud space (such as AWS-S3 bucket). In other words, the segment transfer solution is adopted. For the second case, real-time recording is uploaded to the cloud, and the video stream is divided into blocks and stored in the cloud space (such as AWS-S3 bucket), and playback and download operations are supported. The bucket of AWS-S3 protocol is the de facto standard for object storage. Using AWS-S3 protocol to store data can have the greatest flexibility (multi-cloud architecture) and reliability. In other words, the cloud storage solution is adopted. Cloud storage can meet the requirements of long-term storage and storage in the data center specified by the customer.

[0081] The embodiments of the present application are based on the actual situation of users and personalize the hierarchical storage of recorded videos according to the different storage durations and storage privacy requirements (customer's own data center) for users in the recorded videos. Different storage methods can be used according to event information or regional information, etc., and a balanced combination of the video storage cost and the video storage duration can be achieved, which not only meets the personalized needs of users but also achieves cost reduction and efficiency improvement.
