Description

Technical Field

[0001] This invention relates to the field of testing technology, and specifically to a testing method, apparatus, electronic device, and storage medium for a video fusion platform. Background Technology

[0002] Network cameras: used to collect audio and video resources, package them into RTP streams, and send them to the video surveillance platform. The video surveillance platform: connects to all cameras, collects audio and video streaming media, records them, and provides live and playback streams from all cameras. Interconnection testing with the video fusion platform needs to be performed. For example, it could simulate generating up to 255 analog cameras for the monitoring platform to use, but the access platform only supports ONVIF, limiting its applicability. Furthermore, if inter-platform testing is to be performed, a media platform A that complies with GB28181 and ONVIF is required. First, it connects to the required analog cameras via ONVIF, and then connects to the tested object via the GB28181 protocol. The following technical issues remain:

[0003] The network camera simulation device in this patent involves independent file reading, decoding, and even transcoding for each channel. This device places high demands on CPU and disk I / O. When the number of cameras is excessive during stress testing, the network streams from all cameras to media platform A, and from media platform A to the tested platform, place excessive demands on the network environment, requiring twice the bandwidth. If the network stream from the tested platform is added, the bandwidth requirement triples. Furthermore, the virtual cameras cannot provide playback lists or other playback stream information, necessitating the use of storage devices, thus increasing testing costs. Summary of the Invention

[0029] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] The following describes, with reference to the accompanying drawings, a testing method, apparatus, electronic device, and storage medium for a video fusion platform according to embodiments of the present invention.

[0031] Figure 1 A flowchart illustrating a testing method for a video fusion platform provided in an embodiment of the present invention is shown. Figure 1 As shown, a testing method for a video fusion platform provided in one embodiment of the present invention includes the following:

[0032] S101: Access the input source and video fusion platform, and configure one or more virtual devices and configure simulation test items. The input source includes real network cameras and media files. Configuring one or more virtual devices includes configuring an input source for each virtual device. Each virtual device can be adapted to one input source, and each input source can be adapted to multiple virtual devices.

[0033] The process of accessing the input source includes: accessing the input source based on the GB28181 protocol. Accessing the video fusion platform includes: registering with the video fusion platform, and accessing the platform after successful registration.

[0034] In one embodiment of the present invention, such as Figure 2 As shown, this can be achieved through the data processing layer of a virtual platform. When accessing the input source and the video fusion platform, it includes: managing the input source and managing access to the video fusion platform. Configuring one or more virtual devices includes: managing the virtual devices, where managing the virtual devices includes adding and deleting virtual devices and configuring the input source. The simulated test items include packet loss rate configuration and out-of-order switching configuration.

[0035] Specifically, the data management layer is responsible for the maintenance and management of basic data, including input source maintenance, configuration of virtual platform access to the platform under test, configuration of virtual devices and stream allocation, and configuration of test simulations, etc.

[0036] Input source management supports GB28181 access from physical IPCs (network cameras) and media file input, such as:

[0037] A real IPC, a certain real IPC, first registers to the virtual platform via GB28181, the virtual platform sends a call request to the IPC, and the IPC sends an RTP stream to the virtual platform as one input source. Media file management allows configuring media files as input sources, and the virtual platform cyclically reads the file stream as one input source.

[0038] Platform access management: If a test is to be performed on the platform under test, the virtual platform must first be registered to the video convergence platform under test to enable subsequent functional tests. For example:

[0039] SIP server IP: The SIP server IP address of the platform under test. Registered ID and password: The user ID and password assigned by the video convergence platform under test to the virtual platform for SIP registration.

[0040] Virtual device management: Operations of adding, deleting, checking and modifying virtual devices, providing device list query and input source allocation, etc. For example:

[0041] Add, edit, delete, etc. Device list query: Queries the device list of the platform under test to provide basic data. Stream allocation management: Can set an input source for the current virtual device, where one device has only one input source, but the same input source can be shared by multiple devices.

[0042] Test simulation: Configure some test-specific items, such as packet loss and out-of-order, etc. For example:

[0043] Packet loss rate configuration: A random packet loss rate can be configured, ranging from 0 to 100%, where 0 means no packet loss and 100% means all packets are lost. If the value n is between 0 and 100, it is judged whether n < Rand()%100; if the result is true, the packet is lost, otherwise the packet is not lost. Out-of-order switch configuration: Can configure whether to enable random out-of-order, ranging from 0 to 100%, where 0 means no out-of-order and 100% means all packets are out of order. If the value n is between 0 and 100, it is judged whether n < Rand()%100; if the result is true, two adjacent packets are swapped, otherwise no swap is performed.

[0044] S102: Obtain the signaling sent by the video convergence platform, and process the signaling.

[0045] As Figure 2 shown, this can be implemented by the signaling processing layer of the virtual platform. Specifically, since the platform under test is based on GB28181, all GB28181-related SIP protocols are uniformly processed by this module, mainly including registration, call, live broadcast call response, playback call response, live broadcast close response, playback close response, device list query, playback list query, pan-tilt-zoom control, etc.

[0046] S103: Based on the signaling processing result, process the streaming data of the virtual device, and forward the streaming data of the corresponding data source through the corresponding virtual device, so as to perform functional and stress tests on the video fusion platform through the simulation test items.

[0047] In one embodiment of the present invention, based on the signaling processing result, the streaming data of the virtual device is processed, and the streaming data of the corresponding data source is forwarded through the corresponding virtual device, so as to perform functional and stress testing on the video fusion platform through the simulation test items, including: receiving and processing the streaming data of the virtual device, processing the streaming data, and outputting the streaming data, and forwarding the streaming data of the corresponding data source through the corresponding virtual device, so as to perform functional and stress testing on the video fusion platform through the simulation test items.

[0048] like Figure 2 As shown, this can be achieved through the media streaming layer of a virtual platform, specifically including:

[0049] Stream reception processing handles media data from various input sources, such as RTP streams from real IPCs and file streams from media files. For example:

[0050] The RTP stream parses the RTP packets sent by IPC, removes the packet headers, and places them in a buffer queue, awaiting distribution or processing. The H264 media file stream decapsulates the media files and places them in a buffer queue, awaiting distribution or processing.

[0051] Stream processing includes: Media stream allocation, which allocates media packet pointers to the media packet cache queue of the corresponding virtual device based on the configuration information in virtual device management, for subsequent forwarding; Live broadcast status management, which manages some status information of the live broadcast, such as keep-alive judgment; Replay status management, which manages the following operations and statuses of replay, such as playback, pause, and speed adjustment, for all virtual devices; Dedicated media files are used as replay streams. Since each replay stream requires separate file reading, the number of replay streams supported simultaneously is controlled. In actual scenarios, there is more live broadcasting and less concurrent replay, so no optimization is needed; PTZ control, which forwards PTZ signaling to the real IPC if the current broadcast is live and the input source is a real IPC, and the result is reflected on the screen; if the current broadcast is live and the input source is a media file, the screen is decoded, and the top, bottom, left, and right information is drawn onto the screen, then encoded and output to make the final screen responsive; and a packet loss module that generates random numbers based on a configured percentage. If the packet falls within the hit zone, it is dropped; otherwise, it is forwarded. The out-of-order module generates random numbers based on a configured percentage. If a random number is generated, the order of two adjacent packets is swapped, and the packets are forwarded sequentially. The RTP encapsulation module encapsulates the received network media packets and decapsulated file packets into RTP packets.

[0052] Stream output processing outputs the encapsulated RTP stream to the platform under test, supporting both TCP and UDP transmission. The transmission format is dynamically parsed based on the SDP description of the SIP signaling. For example:

[0053] UDP transmission carries a risk of packet loss and is recommended for strong networks. TCP transmission does not carry a risk of packet loss, but due to the retransmission mechanism, network usage is slightly higher.

[0054] The testing method for the video fusion platform in this invention supports the GB28181 protocol, facilitating inter-platform communication, and provides multiple input sources and multi-channel virtual device outputs. It supports various PTZ control signaling and can decode and re-encode the results before feeding them back to the actual screen, making testing convenient. Since the input sources of multiple virtual devices in memory can be shared, resource consumption is low, allowing for testing of thousands of output channels. It provides packet loss simulation, out-of-order simulation, and dynamic configuration for convenient testing of abnormal stream reception.

[0055] The testing method for a video fusion platform according to embodiments of the present invention supports inputs such as real network cameras and media files, and allows for the addition and configuration of multiple virtual devices and input sources. It supports live stream playback from virtual devices, as well as signaling control such as PTZ control and playback control. By connecting the virtual platform to the video fusion platform under test, the functionality and stress testing of the platform under test are achieved. Furthermore, since the virtual platform can be configured with multiple virtual devices, the cost of stress testing is reduced, and the same input source can be reused by multiple virtual devices, resulting in low resource consumption.

[0056] Figure 3 A schematic diagram of the structure of a test device for a video fusion platform provided in an embodiment of the present invention is shown, as follows: Figure 3 As shown, the testing apparatus for the video fusion platform provided in this embodiment of the invention includes: a data management layer 310, a signaling processing layer 320, and a media stream processing layer 330, wherein:

[0057] The data management layer 310 is used to access input sources and video fusion platform, and to configure one or more virtual devices and configure simulation test items. The input sources include real network cameras and media files. Configuring one or more virtual devices includes configuring an input source for each virtual device. Each virtual device can be adapted to one input source, and each input source can be adapted to multiple virtual devices.

[0058] The signaling processing layer 320 is used to acquire signaling sent by the video fusion platform and process the signaling.

[0059] The media stream processing layer 330 is used to process the stream data of the virtual device based on the processing result of the signaling, and forward the stream data of the corresponding data source through the corresponding virtual device, so as to perform functional and stress tests on the video fusion platform through the simulation test items.

[0060] The testing apparatus for the video fusion platform according to embodiments of the present invention supports inputs such as real network cameras and media files, and can add multiple virtual devices and configure input sources. It supports live stream playback from virtual devices, as well as signaling control such as PTZ control and playback control. By connecting the virtual platform to the video fusion platform under test, the functionality and stress testing of the platform under test are achieved. Furthermore, since the virtual platform can be configured with multiple virtual devices, the cost of stress testing is reduced, and the same input source can be reused by multiple virtual devices, resulting in low resource consumption.
