Description

Background Art

[0002] There are usually two ways to determine the status of a device. The first is to use ping to see if the other party responds to the ping. The second is to access the SDK provided by the device or write an access module to pull the stream, actively query or device callback to see if it is online. Both methods have some disadvantages. The first method cannot accurately reflect the actual status of the device, and the second method cannot be universal. Each manufacturer or type of device needs to access the SDK, which is not universal. Summary of the invention

[0032] Figure 3This is a structural framework diagram corresponding to an electronic device of the present invention. DETAILED DESCRIPTION

[0033] To facilitate understanding of this plan, the professional terms given in this plan are explained:

[0034] ffprobe: An open source tool that is part of the FFmpeg multimedia processing tool suite. It is used to analyze the metadata of media files and provide detailed information about the files. ffprobe is mainly used to inspect and analyze the properties of files without modifying them.

[0035] Network media device: A network device with an IP address, which refers to a camera device or NVR device that can be accessed through a network protocol (such as Hikvision and Dahua digital cameras).

[0036] RTSP: It is a streaming media protocol that network media devices usually support.

[0037] Online status: The device can be pinged and can provide media streaming services normally.

[0038] Offline status: The device cannot be pinged, or the device can be connected but cannot provide media services normally.

[0039] Metadata: This refers to the descriptive information streams of the video data. The information format is standard JSON, such as the encoding format, bit rate, resolution, and other information of the video stream.

[0040] Streaming address: The streaming address here has a wide range and can be RTSP, RTMP, or HTTP.

[0041] URI: The path or parameter following the IP address.

[0042] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] like Figure 1 as well as Figure 2 As shown, a method for determining the status of a network media device based on ffprobe according to an embodiment of the present invention comprises the following steps:

[0044] S1, configuring an ffprobe command for determining the status of a network media device, and sending command line parameters corresponding to the ffprobe command and a streaming address to the network media device to be determined.

[0045] in:

[0046] The ffprobe command refers to the command that needs to be executed by the network media device to be judged, and is edited according to a fixed format, for example: ffprobe -v quiet-print_format json-show_format-show_streams.

[0047] S2, according to the stream pulling address, judging whether the metadata fed back by the network media device to be judged contains the streams keyword, and determining whether the network media device to be judged is online according to the judgment result, wherein the metadata is the data obtained when the network media device to be judged executes the command line parameters.

[0048] Before S2, it also includes: if the device is connected successfully and the rtsp protocol is successfully connected, the video stream description information of the device will be obtained.

[0049] Embodiment 1, this scheme includes 2 important elements, the first element is the configured ffprobe command: ffprobe -v quiet-print_formatjson-show_format-show_streams, the second element is the transmitted stream pull address: the stream pull address URI can be defined arbitrarily without restriction.

[0050] When the detection service starts ffprobe, it passes element 1 and element 2. ffprobe will connect to the device and obtain the corresponding metadata according to the passed stream pull address (element 2). If the device is successfully connected and the rtsp protocol is successfully connected, the device's video stream description information will be obtained. Since the description information returned by different media devices may be different, ffprobe will standardize the output metadata based on the passed parameters (element 1). The metadata information is as follows:

[0051]

[0052]

[0053] The detection service searches for streams information based on the returned metadata. If the information is found, the device is online. If the information fails, the device is offline. If the metadata is {}, the device is offline.

[0054] The design and construction of the present invention is based on ffprobe. The ffprobe multimedia processing tool suite needs to be installed before the program is started. After the program is started, the passed command parameters will be loaded, and ffpobe will be called in the program in command line mode to request the device. The program will output and filter the metadata returned after requesting the device in a standardized manner. If the streams content in the metadata can be correctly parsed, it means that the device is online and can pull video data normally.

[0055] The beneficial effects of the network media device status determination method based on ffprobe provided by the present invention are as follows:

[0056] By pre-configuring the ffprobe command, the efficiency of judging the status of network media devices is improved, and metadata is used to accurately judge the scenarios where the device can be connected but cannot be used normally. The probability of accessing abnormal devices is reduced, and the efficiency of user use of devices and video surveillance experience are improved.

[0057] Furthermore, the ffprobe command is a code generated in a fixed format.

[0058] Furthermore, before determining whether the metadata fed back by the network media device to be determined contains the streams keyword, the following steps are also included:

[0059] When the network media device to be judged is in a state to be detected, it is determined whether the metadata contains the streams keyword, and the state to be detected includes: successful connection and successful protocol docking, the successful connection means that the network media device to be judged is successfully connected to the terminal configured with the ffprobe command for judging the state of the network media device, and the successful protocol docking means that the network media device to be judged and the terminal configured with the ffprobe command for judging the state of the network media device are transmitted through the rtsp protocol.

[0060] It should be noted that when the network media device to be judged is in a non-detection state, a security check is performed on all links corresponding to the terminal configured with the ffprobe command for judging the network media device status (since the terminal configured with the ffprobe command for judging the network media device status may issue ffprobe commands to multiple network media devices to be judged at the same time, when any network media device to be judged is in a non-detection state, a security check is required for all links corresponding to the terminal, and each link connects the terminal with the network media device to be judged), and if the check is passed, S1 is repeated. When the network media device to be judged is still not in a non-detection state after repeating the security check n times, it is judged whether the network media device to be judged is in an online state through manual intervention. Among them:

[0061] The non-to-be-detected status is: connection failure and / or protocol docking failure.

[0062] The specific process of security verification is as follows:

[0063] The first step is to obtain multiple links to be checked through a crawler tool; the crawler tool can be burpsuite.

[0064] In the second step, a request is sent to the server (a terminal configured with the ffprobe command for determining the status of the network media device) according to each link to be checked, and a request result corresponding to each link to be checked is obtained.

[0065] For example, a request is sent to the server for a link found by the crawler. The returned request results may include:

[0066] Headers: return code, Server, Date, Content-Type, Connection, Vary, Accept-Encoding, location_gray, X-XSS-Protection, Referrer-Policy. Log the request and request response results.

[0067] The third step is to analyze any request result to obtain the first return value in any request result; wherein the first return value may be a "Server" return value.

[0068] The process of analyzing the request results may include the following methods:

[0069] The first method: Check whether there is a "Server:" return value in responses. If there is a return value, it means that a middleware leak has occurred, and if there is no return value, it means that no middleware leak has occurred. That is, if the "Server:" return value is not empty, there is a middleware leak, and if the return value is empty, there is no middleware leak.

[0070] The second method: Check whether the return value of "Server:" contains the version number. If leaked, the return value will contain the middleware version number and the middleware name, especially the middleware version number.

[0071] According to the judgment results of the first and second methods, intercept the request link, middleware, and version number of the responses with leaked middleware version numbers; among them, according to the Server result, the Server value is the middleware and version number. The analysis structure can be made into a script to conduct in-depth analysis of the log content.

[0072] In the fourth step, when the first return value satisfies a preset condition, a middleware leak occurs in the corresponding link to be checked.

[0073] Further, the process of determining whether the network media device to be determined is in an online state according to the determination result is:

[0074] When the judgment result is yes, determining that the network media device to be judged is in an online state;

[0075] When the judgment result is no, it is determined that the network media device to be judged is in an offline state.

[0076] In the above embodiments, although the steps are numbered S1, S2, etc., these are only specific embodiments given by the present invention. Those skilled in the art may adjust the execution order of S1, S2, etc. according to actual conditions, which is also within the protection scope of the present invention. It can be understood that in some embodiments, some or all of the above embodiments may be included.

[0077] The present invention also provides a network media device status judgment system based on ffprobe, and the specific technical solution is as follows:

[0078] The configuration module is used to: configure the ffprobe command used to determine the status of the network media device, and send the command line parameters corresponding to the ffprobe command and the streaming address to the network media device to be determined;

[0079] The judgment module is used to: judge whether the metadata fed back by the network media device to be judged contains the streams keyword according to the stream pulling address, and determine whether the network media device to be judged is online according to the judgment result, and the metadata is the data obtained when the network media device to be judged executes the command line parameters.

[0080] Based on the above solution, the present invention can also be improved as follows.

[0081] Furthermore, the ffprobe command is a code generated in a fixed format.

[0082] Furthermore, before determining whether the metadata fed back by the network media device to be determined contains the streams keyword, the following steps are also included:

[0083] When the network media device to be judged is in a state to be detected, it is determined whether the metadata contains the streams keyword, and the state to be detected includes: successful connection and successful protocol docking, the successful connection means that the network media device to be judged is successfully connected to the terminal configured with the ffprobe command for judging the state of the network media device, and the successful protocol docking means that the network media device to be judged and the terminal configured with the ffprobe command for judging the state of the network media device are transmitted through the rtsp protocol.
