Description
Technical Field
The present application relates to video monitoring technologies, and in particular, to a data processing method and apparatus, an electronic device, and a readable storage medium.
Background
In a general monitoring scene, the acquisition of analog signals is completed by a front-end analog camera, and the acquired analog signals are determined by the current scene. In some special cases, however, the user may need an analog signal for a particular scene and want that scene to remain unchanged for a period of time.
For example, in order to test the face recognition function for two different DVR (Digital Video Recorder) devices, in order to maintain the accuracy of the test data, the input scenes of the two DVR devices should be kept identical, and repeated tests may be required for the same input scene. The conventional method is to face a simulation camera to a scene where people often move, the method has high environmental requirements, and the test scene cannot be kept consistent every time in repeated tests. Another method is to find a video file containing a scene where a person often moves, play the video file, and aim the analog camera at the display device being played. The method has low requirement on environment, and can meet the condition that the scenes of each test are consistent, but the video scene of the analog signal acquired by the method is different from the actual scene and is not accordant with the actual scene, so that the accuracy of the final test data is lacked.

As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In order to make the technical solutions provided in the embodiments of the present application better understood and make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions in the embodiments of the present application are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a flow chart of a data processing method provided in an embodiment of the present application is schematically illustrated, where the data processing method may be applied to a device (hereinafter referred to as a data processing device) having a function of converting a video file into an analog signal, and as shown in fig. 1, the data processing method may include the following steps:
and S100, decoding the first target video file into video frame data.
In this embodiment of the present application, the first target video file does not refer to a fixed video file, but may refer to any video file that needs to be converted into an analog signal.
In the embodiment of the application, in order to realize that a plurality of devices perform a test on analog signals of the same scene, a video file of a specific scene may be converted into analog signals, and the analog signals are respectively input to the plurality of devices for testing.
Accordingly, in the embodiment of the present application, for the first target video file that needs to be converted into an analog signal, the input data thereof may be converted into an analog signal by the data processing device.
When the data processing device receives the input first target video file, the data processing device may decode the first target video file to decode the first target video file into a single frame of video data (i.e., video frame data).
It should be noted that, in the embodiment of the present application, the encoding format of the first target video file may be a common encoding format; the video file resolution may support common resolutions such as minimum 128 x 128 support, maximum 4096 x 4096 support; the frame rate can support a common frame rate, such as any frame rate between 1 frame/second and 60 frames/second.
And step S110, outputting the video frame data as a digital signal of a specified protocol.
In the embodiment of the present application, in order to implement conversion from a video file to an analog signal, after the video file is decoded into video frame data, the video frame data needs to be output in the form of a digital signal of a specified protocol.
The digital signal of the specified protocol is a digital signal supporting digital-to-analog conversion (i.e., converting a digital signal into an analog signal).
Accordingly, in the embodiment of the present application, after the data processing device decodes the first target video file into video frame data, the video frame data may also be output as a digital signal of a specified protocol.
And step S120, converting the digital signal of the specified protocol into an analog signal of a target system.
In the embodiment of the present application, the target format does not refer to a fixed analog signal format, but may refer to any format of an analog signal that needs to be output, and the following description of the embodiment of the present application is not repeated.
In the embodiment of the present application, after the data processing device outputs the video frame data as the digital signal of the specified protocol, the digital signal of the specified protocol may be converted into the analog signal of the target system.
In the embodiment of the application, after the data processing device converts the first target video file into the analog signal of the target system, the analog signal of the target system can be output to the designated device according to the requirement, and the designated device performs corresponding processing on the analog signal of the target system.
For example, when the first target video file is a video scene containing people and having a clear face, the data processing device may output the analog signals of the target system to the first DVR and the second DVR, where the first DVR and the second DVR may respectively perform face detection on the analog signals of the target system by using different face detection algorithms, and test the face detection algorithms adopted by the first DVR and the second DVR by using the analog signals that better conform to the actual scene under the condition of ensuring that the scenes are the same.
It can be seen that, in the method flow shown in fig. 1, by converting the video file into the analog signal and outputting the analog signal, the analog signal can conform to the actual scene under the condition that the scene is ensured to be the same. In addition, the same video file can be converted into different analog signal systems according to actual requirements, and the test requirements of analog signals of various systems under the same scene are met.
In one embodiment of the present application, the outputting the video frame data as a digital signal of a specified protocol includes:
setting a digital signal output parameter of a specified protocol according to a target analog signal standard parameter;
and outputting the video frame data into the digital signal of the specified protocol according to the digital signal output parameter of the specified protocol.
In this embodiment, in order to output video frame data as a digital signal of a specified protocol, the data processing apparatus may output a format parameter (referred to herein as a target analog signal format parameter) corresponding to a format of an analog signal that needs to be output (i.e., the above-described target format).
In one example, the target analog signal format parameters may include, but are not limited to, one or more of the following parameters:
a target signal type, a target resolution, and a target frame rate.
The target signal type can be an analog video signal type commonly used in the field of video monitoring; the target resolution may be a common analog signal resolution, such as 720P, 1080P, 3M, 4M, 5M, or 8M, etc.; the target frame rate may be a common analog signal frame rate, such as 12, 15, 25, 30, 50, 60, etc.
In this embodiment, the data processing apparatus may set a digital signal output parameter of a specified protocol according to the target analog signal format parameter, and output the video frame data as a digital signal of the specified protocol according to the digital signal output parameter of the specified protocol.
In one example, the digital signal output parameters of the specified protocol may include, but are not limited to, one or more of the following parameters:
output clock, signal width and height, valid data and blanking region.
Further, in this embodiment, in order to enable the digital signal of the above-mentioned specified protocol to be converted into an analog signal of a target system, a register configuration needs to be performed on the digital-to-analog conversion chip.
Accordingly, the converting the digital signal of the specified protocol into the analog signal of the target system may include:
performing register configuration on the digital-to-analog conversion chip according to the standard parameters of the target analog signal;
and converting the digital signal of the specified protocol into an analog signal of a target system by a digital-to-analog conversion chip.
In this embodiment, the data processing device may configure a register of the digital-to-analog conversion chip according to the target analog signal system parameter, and convert the digital signal of the specified protocol into the analog signal of the target system through the digital-to-analog conversion chip.
It should be noted that, in the embodiment of the present application, the output parameter of the digital signal of the specified protocol (referred to as digital signal output parameter herein) may be determined by the system of the analog signal that is finally required to be output.
The system of the analog signal to be finally output may be configured by a user in real time according to a requirement, or a default configuration may be adopted, for example, the analog signal system configured when the data processing apparatus leaves a factory may be used as the analog signal system of the default configuration.
Accordingly, in one embodiment of the present application, before outputting the video frame data as the digital signal of the specified protocol, the method may further include:
receiving an analog signal system configuration instruction; the analog signal system configuration instruction carries a target analog signal system parameter.
In this embodiment, when the video file needs to be converted into the analog signal, the user may determine the format of the analog signal that needs to be output according to the actual requirement, and issue an analog signal format configuration instruction carrying the format parameter of the target analog signal to the data processing device.
When the data processing device receives the analog signal format configuration instruction, a target analog signal format parameter carried in the analog signal format configuration instruction may be obtained, and digital signal output parameter setting of a specified protocol and register configuration of a digital-to-analog conversion chip are performed according to the target analog signal format parameter.
Further, in the embodiment of the present application, it is considered that in some special scenarios, it may be necessary to convert the encoding format of the video file and adjust the resolution and/or the frame rate, but the resolution or the frame rate of the transcoded video file cannot be higher than that of the video file before transcoding due to the current common transcoding function.
According to the data processing scheme provided by the embodiment of the application, the video file can be converted into the analog signal with the corresponding resolution and frame rate, and then the analog signal is encoded with the corresponding resolution and frame rate, so that the video file can be converted into other video files with different encoding formats, different resolutions and/or different frame rates.
Accordingly, in one embodiment of the present application, after converting the digital signal of the specified protocol into the analog signal of the target format, the method may further include:
and coding the analog signal of the target system to obtain a second target video file.
In this embodiment, after the data processing device converts the first target video file into the analog signal of the target format, the data processing device may further encode the analog signal of the target format to obtain a corresponding video file (referred to as a second target video file herein).
In one example, the resolution or/and frame rate of the second target video file is higher than the resolution or/and frame rate of the first target video file.
It should be noted that, in this embodiment of the application, after the data processing device converts the first target video file into the analog signal of the target format, the analog signal of the target format may also be output to a specified encoder device, and the encoder device performs encoding on the analog signal of the target format at a corresponding resolution and/or frame rate to obtain the second target video file, which is not described herein again in detail.
In addition, in the embodiment of the present application, the resolution and/or the frame rate of the second target video file may also be lower than or equal to the resolution and/or the frame rate of the first target video file.
