Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
In this application, unless explicitly stated or limited otherwise, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one feature. In the description of the present invention, "a plurality" means at least two, for example, two, three, unless specifically defined otherwise. The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
It should be noted that, the data recording method based on the web page of the present application may be implemented based on a software program, and thus, the data recording method may be run on a server or a computer or other devices.
Fig. 1 is a flowchart of a data recording method based on a web page according to an embodiment of the present application; as shown in fig. 1, the method includes:
step 101: and responding to the task opening instruction, and downloading and acquiring the webpage code of the graphical interface of the current webpage based on a preset browser.
It should be noted that, in a possible implementation manner, the task starting instruction may be issued by the user according to the use requirement, that is, the task starting instruction is issued by operating a control of the related device, a case, or inputting an instruction, for example, without limitation.
It should be further noted that the assignment of the task opening command may also be implemented based on a software program. In a possible implementation manner, the task start instruction is an operation start instruction of the software program, that is, after the software starts to operate, the task starts, that is, the method step in step 101 starts to be executed.
In another possible implementation manner, the task starting instruction is different from the operation starting instruction of the software program, and in this implementation manner, after the software program receives the operation starting instruction, the software program starts to operate and waits for the task starting instruction; the method steps in step 101 begin after a task start instruction is captured.
It should be noted that the task start instruction may be an instruction set according to time, for example, the task start instruction is sent at a specific time according to a timing setting, so that the software program executes the subsequent steps. For example, if a task start command is sent every 01:00:00 pm, the method of the present application may respond after the task start command is captured at that time. The task starting instruction can also be a trigger condition, namely the task starting instruction is sent after the set condition is met, so that the software program starts to operate, and the subsequent steps are executed. For example, after a specific webpage is captured and opened, a task opening instruction is sent, and then the method of the application can respond after the specific webpage is opened and the task opening instruction is captured.
The above is merely an example, and in actual use, there may be other ways of issuing the task start instruction and other forms of task start instruction, which is not limited in the present application.
And after a task opening instruction is received, downloading and acquiring a webpage code of a graphical interface of the current webpage based on a preset browser.
The application does not limit the operating system on which the provided data recording method based on the web page is based, and in a possible implementation manner, the data recording method based on the web page may be implemented based on a Linux (GNU/Linux), which is only an example.
The specific type of the preset browser is not limited, as long as the browser can be developed for the second time, and in a specific implementation mode, the preset browser can be an open-source chrome browser.
For example, in a specific implementation, an open-source chrome browser is used, the chrome browser is set to a handle mode, and after a webpage is opened (i.e., a website address is opened, or a Uniform Resource Locator (URL) is opened), the code of the current webpage is downloaded.
It should be noted that the code for downloading the current webpage may be all codes for downloading the current webpage, and the codes are executed to obtain some operation information; the downloading of the code of the current webpage can also be that after all webpage codes of the current webpage are downloaded, preset codes are injected into the webpage codes, and the logic of the webpage codes is verified or recording time is marked. The logic check of the webpage code means that the logic of the webpage code is judged according to the feedback or the running condition of the webpage by injecting a preset code into the downloaded webpage code so as to evaluate the stability, the safety and the like of the webpage code. Recording the mark recording time to the web page means that the current recording time is marked on the recorded video in a watermark or other forms at the same time of recording.
The above is merely an example, and in actual implementation, the code for downloading the current web page may be in other downloading forms, which is not limited in the present application as long as the web page code of the graphical interface of the current web page is obtained and the preset function operation is implemented.
It should be further noted that, if the operation that needs to be performed on the graphical interface of the current page is recorded, the operation may also be implemented in a manner of replacing the web page code, that is, in response to the task start instruction, the new replacement data is used to replace the source code data in the web page code of the current web page corresponding to the page code, so that the web page code of the graphical interface of the new current web page corresponding to the replaced web page code may be called, thereby implementing the recording of the web page operation. The new replacement data may be new replacement data input by a user after the task is started, or may be new replacement data stored in advance, and a specific source of the new replacement data is not limited in the present application. The operation effect of clicking, selecting and the like on the current webpage can be realized by using the mode of replacing the codes, and the operation effect is the same as the operation effect realized by a user through the peripheral equipment. The above is merely an example, and there may be other ways to obtain the operation on the code level, which is not limited in the present application, and the operation on the graphical interface of the current page may be implemented.
In a specific implementation manner, replacement data of a code corresponding to implementation of a specific position selection operation is prestored in a target webpage, and in response to a task starting instruction, if it is detected that the current webpage is the target webpage of prestored new replacement data, source code data in a webpage code of the current webpage corresponding to the new replacement data in the webpage code are replaced, and by calling the replaced webpage code, a response corresponding to the current webpage can be obtained, so that a response in the code form of the selection operation is obtained.
The web page code of the graphical interface of the current web page in the present application includes, but is not limited to, font effect, map, table syntax, split window, structural definition, connection and graph, background and color, etc. the present application does not limit the specific content included in the web page code of the graphical interface, and the code related to the presentation mode and effect of the graphical interface all belong to the range of the web page code of the graphical interface. In practical application, the content contained in the page code of the graphical interface can be flexibly set according to practical use and recording requirements.
Step 102: and converting and acquiring current interface data in a preset format according to the webpage codes.
It should be noted that, in the present application, the data of the web page is finally recorded and synthesized into a video, and the video is transmitted to the terminal for display, and different terminals have different requirements on the format, resolution, frequency, code rate, and the like of the video. Therefore, when the task starting instruction is responded, the current interface data in a preset format can be acquired, and the preset format comprises but is not limited to a preset resolution, a preset frame rate, a preset code rate and the like. In the application, the codes are downloaded and acquired in steps 101 and 102, so that the current interface refers to interface coded data.
It should be further noted that the preset format may be set by a developer in a software program, for example, to classify common web pages: setting different preset formats for the video type web pages, the image type web pages and the character type web pages compared with the same type web pages, and acquiring the preset formats of the web pages by acquiring the classification of the web pages after responding to the task starting instruction; the preset format can also be manually set by a developer when a task start instruction is reached. The above is merely an example, and in a specific implementation process, there may be other ways to set the preset format, for example, a default value meeting most of the use requirements may be set, and after a corresponding task start instruction, the default value is the preset format of the web page, and the like, which is not limited in the present application.
In one possible implementation, the current web page is a video-type web page, and the preset format set by the developer is as follows: and if the preset resolution is a pixel, the preset frame rate is cHz, and the preset code rate is dbit/s, the format of the current interface data obtained by conversion is a pixel with the resolution, the frame rate is cHz, and the code rate is d bit/s (a, b, c, d are all greater than 0). For example, in a specific implementation, the current web page is a video-type web page, and the preset format set by the developer is as follows: the preset resolution is 1280 × 720 pixels, the preset frame rate is 10Hz, and the preset code rate is 1 Mbit/s. The format of the obtained current interface data is converted into the format with the resolution of 1280 × 720 pixels, the frame rate of 10Hz and the code rate bit of 1 Mbit/s.
Step 103: and storing the current interface data in a preset format into a memory.
And storing the current interface data in the preset format obtained in the step 102 into a memory for subsequent calling.
In summary, an embodiment of the present application provides a data recording method based on a web page, including: responding to a task opening instruction, and downloading and acquiring a webpage code of a graphical interface of a current webpage based on a preset browser; converting and acquiring current interface data in a preset format according to the webpage codes; and storing the current interface data in a preset format into a memory. Compared with the prior art of recording a webpage based on a graphical interface, the method has the advantages that the current interface data are called in the form of codes, on one hand, the codes consume less CPU and memory, smooth and efficient transmission of data is facilitated, and stable operation of a software program is facilitated; the operation is realized by using the codes, so that the webpage recording based on the image interface can be separated from manual on-duty automatic operation. On the other hand, the format of the acquired current interface data meets the preset format requirement, so that the interface data can be used without denoising, rendering, processing and the like, and the diversified webpage data recording requirement of a user can be met.
Optionally, on the basis of fig. 1, the present application further provides a possible implementation manner of a data recording method based on a web page, and fig. 2 is a flowchart of a data recording method based on a web page according to another embodiment of the present application; as shown in fig. 2, after storing the current interface data in the preset format in the memory, the method includes:
step 201: extracting current interface data from a memory at a preset frequency;
for the current interface data stored in the memory in step 103, the current interface data may be extracted according to a preset frequency by using a secondary development tool when the current interface data needs to be synthesized. It should be noted that the preset frequency may be set in a software program by a developer, and after responding to a task start instruction (step 101), the preset frequency of the web page is obtained; the preset frequency can also be set manually by a developer when a task start instruction is reached. The above is merely an example, and in a specific implementation process, there may be other ways to set the preset frequency, for example, a default value meeting most of the use requirements may be set, and after a corresponding task start instruction, the default value is the preset frequency of the web page, and the like, which is not limited in the present application.
For example, assuming the default frequency is 25 frames/second, the steps 201 and 202 are performed using an open-source Chrome browser and a secondary development tool browser development suite (Chrome DevTools Protocol). Then decimation is performed at a preset frequency of 25 frames/second using Chrome DevTools Protocol.
Step 202: and synthesizing the video file to be transmitted according to the extracted current interface data.
It should be noted that, in a specific implementation manner, the preset format in step 102 further includes an image generation manner for the extracted current interface data, so as to generate an image in a target format. For example, in the preset format, the image generation mode of the current interface data is the JPEG format, which means that lossy compression is required to be performed on the current interface data, and a JPEG-format picture meeting the preset resolution requirement is generated after redundant image data is removed. Similarly, according to actual use requirements, the image generation mode of the current interface data may also be a PNG format, a TIF format, or the like, which is not limited in the present application.
And extracting the current interface data from the memory at a preset frequency, and generating an image in a corresponding format according to the extracted current interface data in a set image generation mode for the extracted current interface data. And secondly, performing video synthesis on the generated images with the corresponding formats according to the extraction sequence and the preset frequency to obtain a video file to be transmitted.
In a specific implementation manner, the image generation manner of the current interface data in the preset format is a JPEG format, the preset frequency is 25 times/second, and a secondary development tool Chrome DevTools Protocol is used to generate a JPEG-format picture meeting the preset resolution requirement on the extracted current interface data. And secondly, performing video synthesis on the generated images with the corresponding formats according to the extraction sequence and the frequency of 25 sheets/second to obtain a video file to be transmitted.
The current interface data are extracted from the memory and then synthesized into the video file with transmission, so that the conversion from codes to videos of the current webpage recording is realized, the conversion mode is simple, the frame rate can be set and adjusted according to the use requirements of users, and the method has high flexibility.
Optionally, on the basis of fig. 2, the present application further provides a possible implementation manner of a data recording method based on a web page, and fig. 3 is a flowchart of a data recording method based on a web page according to another embodiment of the present application; in some embodiments, the recorded object includes an audio source, i.e., some audio content, and as shown in fig. 3, the method includes:
step 301: responding to a task opening instruction, and acquiring a sound source corresponding to the current webpage;
it should be noted that after responding to the task start instruction, there are various ways to acquire the sound source corresponding to the current web page. In a possible implementation manner, the manner of acquiring the sound source corresponding to the current webpage may be that the operating system automatically identifies and acquires, for example, there are N sound sources (N >0) in the operating system, and after a task start instruction, the states of M sound sources (N ≧ M >0) change (the state is changed from an inactive state to an active state), and then the operating system identifies the M sound sources as the sound source corresponding to the current webpage.
In another possible implementation manner, the manner of acquiring the sound source corresponding to the current webpage may be to manually input a number of the sound source corresponding to the current webpage, each sound source has a unique number in the operating system, and the user may manually input the number to acquire information of the sound source.
In another possible implementation manner, the manner of obtaining the sound source corresponding to the current webpage may be a default sound source, that is, one or more default sound sources are set in the operating system, and in response to the task starting instruction, the plurality of sound sources are obtained as the sound source corresponding to the current webpage. In another possible implementation manner, the manner of obtaining the sound source corresponding to the current webpage may be controlled through a webpage interface, and the sound source expected by the user is selected.
The above is merely an example, and the specific implementation manner of obtaining the sound source corresponding to the current webpage is not limited in the present application, and the sound source corresponding to the current webpage can be obtained.
In a specific implementation manner, an Ubuntu operating system is used, and the operating system responds to a task opening instruction, acquires sound source information from a browser and an audio console (pulseaudioi), judges the source of the sound source information, and confirms a sound source corresponding to a current webpage from the sound source information.
Step 302: and if the number of the sound sources is one, acquiring sound data of the sound sources.
After the operating system judges the sound source corresponding to the current webpage, if the corresponding sound source is only one, the sound data of the sound source is obtained.
In a specific implementation manner, after the Ubuntu operating system confirms that there is only one corresponding sound source, the sound data of the sound source is transmitted to an audio console (pulseaudioi).
The recording of the audio data in the webpage data recording process is realized by acquiring the sound source corresponding to the current page, and the sound source can be automatically identified through the system, so that the webpage-based data recording method is more intelligent and convenient.
Optionally, on the basis of fig. 3, the present application further provides a possible implementation manner of a data recording method based on a web page, where the method includes:
and if the number of the sound sources is multiple, mixing the sounds of the sound sources to obtain sound data after sound mixing.
It should be noted that, if the sound data corresponding to the current web page is stereo, there are usually two sound sources; if the sound data corresponding to the current webpage is 5.1 sound, five sound sources are usually available; i.e. the number of sound sources differs for different sound data types. After judging the sound source corresponding to the current webpage, the operating system determines the number of the sound sources corresponding to the webpage and the specific sound source number, then the sound of the sound sources needs to be mixed, the operating system calls an interface of an audio console through software to realize sound mixing, and sound data after sound mixing are obtained.
In a specific implementation manner, after confirming that there are five corresponding sound sources, the Ubuntu operating system calls an interface of an audio console through software, and transmits sound data of the five sound sources to the audio console (pulseaudioi), and the audio console performs sound mixing processing on the sound data of the five sound sources.
When the number of the sound sources is multiple, the sound of the multiple sound sources is mixed, the sound data after the mixed sound is obtained, and the quality of recording the sound data corresponding to the current webpage is ensured.
Optionally, on the basis of the foregoing embodiment and fig. 3, the present application further provides a possible implementation manner of a data recording method based on a web page, where the method includes: and synthesizing a new video file to be transmitted according to the video file to be transmitted and the sound data.
The video file to be transmitted and the sound data acquired in the subsequent steps are synthesized in step 202, and a new video file to be transmitted is obtained. The video file to be transmitted obtained in step 202 essentially includes a plurality of picture files and a predetermined frequency. In a possible implementation manner, when synthesizing the video file to be transmitted and the sound data, the audio/video portability can be performed by using a software program, for example, the playing time of the video file to be transmitted and the playing time of the sound data are aligned. The above is merely an example, and in an actual implementation, there may be other synthesis manners, and the present application does not limit a specific synthesis manner, and it is sufficient to synthesize a video file to be transmitted and sound data.
In a specific implementation manner, the audio and video can be written through an audio and video encoding and decoding program (e.g., ffmpeg), and since the software is open-source, the normal operation of the software in the data recording method based on the webpage can be realized.
