Technical Field

[0001] This application relates to the field of network technology, and in particular to a video stream compression method, apparatus, computer equipment, and storage medium. Background Technology

[0002] In existing technologies, the SRv6 Policy mechanism can be used to specify forwarding paths for video streams, ensuring that they traverse the network according to a predetermined strategy, thereby achieving path optimization and centralized compression processing of video streams.

[0003] However, due to the centralized compression processing, all video streams must first be aggregated to the central node before compression processing, which causes a surge in bandwidth pressure on the new metropolitan area network and backbone links, especially in scenarios with large-scale concurrent video streams, which can easily lead to congestion, packet loss and other problems. Summary of the Invention

[0004] Therefore, it is necessary to provide a video stream compression method, apparatus, computer equipment, and storage medium that can alleviate bandwidth pressure when compressing video streams, in order to address the above-mentioned technical problems.

[0008] The system receives the compressed video stream to be processed from the processing server and sends the compressed video stream to the cloud device.

[0014] In one embodiment, the processing server caches keyframe information of the video stream to be processed, and the method further includes:

[0016] Based on the frame number identifier to be supplemented contained in the frame supplementation request, the frame data corresponding to the frame number identifier to be supplemented is selected from the keyframe information of the video stream to be processed that is cached by the processing server.

[0017] The frame data is sent to the controller.

[0018] In one embodiment, sending the frame data to the controller includes:

[0019] The frame data is encapsulated using the Internet Basic Protocol (SRv6) and the encapsulated frame data is sent to the controller.

[0020] In one embodiment, the edge node is connected to at least two processing servers. The step of selecting frame data corresponding to the frame number to be supplemented from the keyframe information of the video stream to be processed cached by the processing servers, based on the frame supplementation request containing the frame number identifier to be supplemented, includes:

[0021] Among the processing servers, determine the target server corresponding to the frame replacement request;

[0022] Based on the frame number identifier to be supplemented contained in the frame supplementation request, the frame data corresponding to the frame number identifier to be supplemented is selected from the keyframe information of the video stream to be processed cached by the target server.

[0023] Secondly, this application also provides a video stream compression device configured at an edge node, the device comprising:

[0024] A determination module is used to determine the video stream processing strategy corresponding to the video stream to be processed; wherein, the video stream processing strategy is sent by the controller to the edge node;

[0025] The sending module is used to add the strategy identifier corresponding to the video stream processing strategy to the video to be processed, and send the video to be processed with the strategy identifier to the processing server, so that the processing server compresses the video stream to be processed according to the video stream processing strategy corresponding to the strategy identifier, and sends the compressed video stream to be processed back to the edge node.

[0026] The receiving module is used to receive the compressed video stream to be processed sent by the processing server and send the compressed video stream to the cloud device.

[0027] Thirdly, this application also provides a computer device. The computer device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to perform the following steps:

[0028] Determine the video stream processing strategy corresponding to the video stream to be processed; wherein, the video stream processing strategy is sent by the controller to the edge node;

[0029] The strategy identifier corresponding to the video stream processing strategy is added to the video to be processed, and the video to be processed with the strategy identifier is sent to the processing server, so that the processing server compresses the video stream to be processed according to the video stream processing strategy corresponding to the strategy identifier, and sends the compressed video stream to be processed back to the edge node.

[0030] The system receives the compressed video stream to be processed from the processing server and sends the compressed video stream to the cloud device.

[0033] The strategy identifier corresponding to the video stream processing strategy is added to the video to be processed, and the video to be processed with the strategy identifier is sent to the processing server, so that the processing server compresses the video stream to be processed according to the video stream processing strategy corresponding to the strategy identifier, and sends the compressed video stream to be processed back to the edge node.

[0034] The system receives the compressed video stream to be processed from the processing server and sends the compressed video stream to the cloud device.

[0038] The system receives the compressed video stream to be processed from the processing server and sends the compressed video stream to the cloud device.

[0039] The aforementioned video stream compression method, apparatus, computer equipment, and storage medium allow edge nodes to determine the video stream processing strategy corresponding to the video stream to be processed. This involves adding a strategy identifier corresponding to the strategy to the video stream to be processed and sending the video stream with the strategy identifier to the processing server. The processing server then compresses the video stream according to the strategy and sends the compressed video stream back to the edge node. The edge node then receives the compressed video stream from the processing server and sends it to the cloud device. As can be seen from the above, this application does not change the existing network architecture during video stream compression. Instead, by receiving the video stream processing strategy sent by the controller, it achieves targeted video stream compression for different types of video streams. This overcomes the limitations of traditional video compression relying on static configuration or centralized processing, enabling dynamic distribution and real-time adjustment of compression strategies. This provides greater flexibility and adaptability. Therefore, this application not only effectively alleviates the problem of backbone network bandwidth constraints but also significantly improves the stability of video transmission and packet loss recovery efficiency.

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0049] The video stream compression method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, edge node 102 communicates with cloud device 103 and controller 104 via a network. A data storage system can store the data that controller 104 needs to process. The data storage system can be integrated on server 104 or placed in the cloud or on other network servers. The edge node determines the video stream processing strategy corresponding to the video stream to be processed, adds a strategy identifier corresponding to the video stream processing strategy to the video stream to be processed, and sends the video stream to be processed with the strategy identifier to the processing server. The processing server then compresses the video stream to be processed according to the video stream processing strategy corresponding to the strategy identifier, and sends the compressed video stream back to the edge node. The edge node then receives the compressed video stream sent by the processing server and sends the compressed video stream to the cloud device.

[0050] In one embodiment, such as Figure 2 As shown, a video stream compression method is provided, which can be applied to... Figure 1 Taking edge node 102 as an example, the explanation includes the following steps:

[0051] S201, Determine the video stream processing strategy corresponding to the video stream to be processed.

[0052] The video stream processing strategy is sent from the controller to the edge nodes.

[0053] It should be noted that the controller generates different candidate processing strategies based on actual business needs, and the video stream types corresponding to different candidate processing strategies are also different. Then, the controller sends each candidate processing strategy to the edge nodes. After receiving the video stream to be processed, the edge nodes select the corresponding video stream processing strategy from among the candidate processing strategies based on the video stream type of the video stream to be processed.

[0054] S202, add the policy identifier corresponding to the video stream processing policy to the video to be processed, and send the video to be processed with the policy identifier to the processing server, so that the processing server can compress the video stream to be processed according to the video stream processing policy corresponding to the policy identifier, and send the compressed video stream to be processed back to the edge node.

[0055] The processing server is an edge processing server deployed alongside the edge node. It adopts a DPDK+ smart network card hardware acceleration architecture, which can realize high-speed decapsulation, bitrate compression, key frame caching and frame interpolation of video streams without modifying the main path structure, thus avoiding impacting the performance of the original business links.

[0056] S203 receives the compressed video stream to be processed from the processing server and sends the compressed video stream to the cloud device.

[0057] In one embodiment of this application, the compressed video stream to be processed needs to be re-encapsulated into an SRv6 message, and then the encapsulated SRv6 message is sent to the cloud device.

[0058] Furthermore, cloud devices can detect the video stream quality of the video stream to be processed in real time and feed the video stream quality back to the controller, so that the controller can dynamically adjust the candidate processing strategy sent later according to the quality of the video stream, so as to ensure the compression quality of the video stream to be processed.

[0059] The aforementioned video stream compression method involves edge nodes determining the video stream processing strategy corresponding to the video stream to be processed, adding a strategy identifier corresponding to the strategy to the video stream to be processed, and sending the video stream to be processed with the strategy identifier to the processing server. The processing server then compresses the video stream according to the video stream processing strategy corresponding to the strategy identifier and sends the compressed video stream back to the edge node. The edge node then receives the compressed video stream from the processing server and sends it to the cloud device. As can be seen from the above, this application does not change the existing network architecture during video stream compression. Instead, by receiving the video stream processing strategy sent by the controller, it achieves targeted video stream compression processing for different types of video streams. This overcomes the limitations of traditional video compression relying on static configuration or centralized processing, realizing dynamic distribution and real-time adjustment of compression strategies, and possessing higher flexibility and adaptability. Therefore, this application not only effectively alleviates the problem of backbone network bandwidth resource shortages but also significantly improves the stability of video transmission and packet loss recovery efficiency.

[0060] In one embodiment, such as Figure 3 As shown, when it is necessary to determine the video stream processing strategy corresponding to the video stream to be processed, the following can be included:

[0061] S301 receives the video stream to be processed.

[0062] It should be noted that the video stream to be processed can come from many sources, such as smart city video surveillance, telemedicine, online education, etc. Therefore, the provider of the video stream to be processed is not limited here.

[0063] S302, select the video stream processing strategy corresponding to the video stream to be processed from at least one candidate processing strategy according to the video stream type corresponding to the video stream to be processed.

[0064] It should be noted that when it is necessary to select a video stream processing strategy corresponding to the video stream to be processed from at least one candidate processing strategy based on the video stream type corresponding to the video stream to be processed, the following may be included: the candidate processing strategy with the same applicable type as the video stream type corresponding to the video stream to be processed shall be used as the video stream processing strategy corresponding to the video stream to be processed.

[0065] In one embodiment of this application, after acquiring the video stream to be processed, type analysis can be performed on the video stream to be processed to determine the video stream type of the video stream to be processed; then, the applicable type of each candidate processing strategy is traversed, and the candidate processing strategy with the same applicable type as the video stream type corresponding to the video stream to be processed is used as the video stream processing strategy corresponding to the video stream to be processed.

[0066] The above-mentioned video stream compression method ensures the smooth progress of the subsequent video stream compression process by selecting the corresponding video stream processing strategy from at least one candidate processing strategy according to the video stream type of the video stream to be processed.

[0067] In one embodiment, such as Figure 4 As shown, if the processing server caches keyframe information of the video stream to be processed, the following may also be included:

[0068] S401 receives frame interpolation requests sent by cloud devices.

[0069] It should be noted that when the cloud device detects frame loss in the video stream, it can use SRv6 control to send a frame replacement request to the edge node, so that the edge node can receive the frame replacement request sent by the cloud device.

[0070] S402, based on the frame number identifier to be supplemented contained in the frame supplementation request, select the frame data corresponding to the frame number identifier to be supplemented from the key frame information of the video stream to be processed cached by the processing server.

[0071] It should be noted that the keyframe information records at least one frame data and a candidate identifier corresponding to each frame data. Then, each candidate identifier is compared with the identifier of the number of frames to be supplemented, and the frame data corresponding to the candidate identifier that is the same as the identifier of the number of frames to be supplemented is taken as the frame data corresponding to the identifier of the number of frames to be supplemented.

[0072] In one embodiment of this application, at least two processing servers are attached to the edge node. When it is necessary to select the frame data corresponding to the frame number to be supplemented from the keyframe information of the video stream to be processed cached by the processing server according to the frame number to be supplemented identifier contained in the frame supplementation request, the following may be included: determining the target server corresponding to the frame supplementation request among the processing servers; selecting the frame data corresponding to the frame number to be supplemented from the keyframe information of the video stream to be processed cached by the target server according to the frame number to be supplemented identifier contained in the frame supplementation request.

[0073] When it is necessary to determine the target server corresponding to the frame interpolation request, the video stream identifier contained in the frame interpolation request can be obtained. Then, from the video stream processing records of each processing server, the processing server that has processed the video stream corresponding to the video stream identifier is selected, and the processing server that has processed the video stream corresponding to the video stream identifier is set as the target server.

[0074] To further explain, a multi-edge node collaborative frame interpolation mechanism can be constructed to adapt to scenarios such as large-scale event live streaming or concurrent uploads from multiple cameras causing regional network congestion. Multiple processing servers share cache state information through the control plane. Each processing server caches keyframe information processed locally and registers it in the global cache directory. When an edge node receives a frame interpolation request from the cloud but the corresponding processing server does not have the corresponding cache locally, the controller routes the request to other nodes. The target node extracts the required frame data, encapsulates it into an SRv6 message, and directly sends it back to the cloud, achieving cross-node frame interpolation response.

[0075] S403 sends frame data to the controller.

[0076] It should be noted that when frame data needs to be sent to the controller, the following may be included: encapsulating the frame data with Internet Basic Protocol (SRv6) and sending the encapsulated frame data to the controller.

[0077] The aforementioned video stream compression method, without altering the existing network architecture, achieves efficient compression and integrity assurance of video streams. This solution not only effectively alleviates the problem of strained backbone network bandwidth resources but also significantly improves the stability of video transmission and packet loss recovery efficiency. It boasts multiple advantages, including low deployment cost, strong scalability, and wide applicability, making it highly valuable for commercial promotion.

[0078] In one embodiment, such as Figure 5 As shown, when video stream compression is required, the following can be included:

[0079] S501 receives the video stream to be processed.

[0080] S502, the candidate processing strategy with the same applicable type as the video stream type corresponding to the video stream to be processed is used as the video stream processing strategy corresponding to the video stream to be processed; wherein, the video stream processing strategy is sent to the edge node by the controller.

[0081] S503, add the policy identifier corresponding to the video stream processing policy to the video to be processed, and send the video to be processed with the policy identifier to the processing server, so that the processing server can compress the video stream to be processed according to the video stream processing policy corresponding to the policy identifier, and send the compressed video stream to be processed back to the edge node.

[0082] S504 receives the compressed video stream to be processed from the processing server and sends the compressed video stream to the cloud device.

[0083] The S505 receives frame interpolation requests sent by cloud devices.

[0084] S506: Based on the frame number identifier to be supplemented contained in the frame supplementation request, select the frame data corresponding to the frame number identifier to be supplemented from the keyframe information of the video stream to be processed cached by the processing server.

[0085] The S507 encapsulates the frame data using the Internet Basic Protocol (SRv6) and sends the encapsulated frame data to the controller.

[0086] In one embodiment, to ensure the efficiency and security of the video stream during transmission, as follows: Figure 6 As shown, the edge router first needs to configure an RTSP traffic redirection policy through the network controller to ensure that only relevant control plane traffic is forwarded to the edge router when pulling RTSP video streams from the cloud. During this process, DPDK reads the interaction information established during the initial video stream pull session to identify the data plane port and passes this information to the network controller. Subsequently, the controller configures the edge router's data plane SR Policy based on this information to achieve precise control over data plane traffic. Once the SR Policy is configured, all subsequent data plane packets (i.e., video streams) will be encapsulated in SRv6 format and transmitted to the cloud after processing by the DPDK module. Furthermore, in case of anomalies such as missing keyframes, the cloud can request cached data stored in the queue from the edge application, thereby ensuring the continuity and integrity of the video stream. This mechanism not only improves the system's fault tolerance but also effectively guarantees the quality of the user experience.

[0087] The aforementioned video stream compression method involves edge nodes determining the video stream processing strategy corresponding to the video stream to be processed, adding a strategy identifier corresponding to the strategy to the video stream to be processed, and sending the video stream to be processed with the strategy identifier to the processing server. The processing server then compresses the video stream according to the video stream processing strategy corresponding to the strategy identifier and sends the compressed video stream back to the edge node. The edge node then receives the compressed video stream from the processing server and sends it to the cloud device. As can be seen from the above, this application does not change the existing network architecture during video stream compression. Instead, by receiving the video stream processing strategy sent by the controller, it achieves targeted video stream compression processing for different types of video streams. This overcomes the limitations of traditional video compression relying on static configuration or centralized processing, realizing dynamic distribution and real-time adjustment of compression strategies, and possessing higher flexibility and adaptability. Therefore, this application not only effectively alleviates the problem of backbone network bandwidth resource shortages but also significantly improves the stability of video transmission and packet loss recovery efficiency.

[0088] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0089] Based on the same inventive concept, this application also provides a video stream compression apparatus for implementing the video stream compression method described above. The solution provided by this apparatus is similar to the implementation described in the above method; therefore, the specific limitations in one or more video stream compression apparatus embodiments provided below can be found in the limitations of the video stream compression method described above, and will not be repeated here.

[0090] In one embodiment, such as Figure 7 As shown, a video stream compression device is provided, comprising: a determining module 10, a sending module 20, and a receiving module 30, wherein:

[0091] The determination module 10 is used to determine the video stream processing strategy corresponding to the video stream to be processed; wherein, the video stream processing strategy is sent to the edge node by the controller.

[0092] The sending module 20 is used to add the policy identifier corresponding to the video stream processing strategy to the video to be processed, and send the video to be processed with the policy identifier to the processing server, so that the processing server can compress the video stream to be processed according to the video stream processing strategy corresponding to the policy identifier, and send the compressed video stream to be processed back to the edge node.

[0093] The receiving module 30 is used to receive the compressed video stream to be processed sent by the processing server and send the compressed video stream to the cloud device.

[0094] In one embodiment, a video stream to be processed is received;

[0095] Based on the video stream type corresponding to the video stream to be processed, select the video stream processing strategy corresponding to the video stream to be processed from at least one candidate processing strategy.

[0103] The aforementioned video stream compression device involves edge nodes determining the video stream processing strategy corresponding to the video stream to be processed, adding a strategy identifier corresponding to the strategy to the video stream to be processed, and sending the video stream to be processed with the strategy identifier to the processing server. The processing server then compresses the video stream according to the video stream processing strategy corresponding to the strategy identifier and sends the compressed video stream back to the edge node. The edge node then receives the compressed video stream from the processing server and sends it to the cloud device. As can be seen from the above, this application does not change the existing network architecture during video stream compression. Instead, by receiving the video stream processing strategy sent by the controller, it achieves targeted video stream compression for different types of video streams, breaking through the limitations of traditional video compression that relies on static configuration or centralized processing. It realizes dynamic distribution and real-time adjustment of compression strategies, possessing higher flexibility and adaptability. Therefore, this application not only effectively alleviates the problem of backbone network bandwidth resource shortages but also significantly improves the stability of video transmission and packet loss recovery efficiency.

[0104] Each module in the aforementioned video stream compression device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in hardware within or independently of the processor in a computer device, or stored in software within the memory of the computer device, so that the processor can call and execute the corresponding operations of each module.
