Description

data acquisition method and device

Technical Field

The invention relates to the technical field of data processing, in particular to a data acquisition method and device.

Background

With the rapid development of internet technology, more and more functions can be realized by an operating system carried by a client. For example, the data acquisition function provided by the operating system may acquire data displayed in a Flash (animation editor) window according to an instruction of a home terminal user; the displayed data can be static data or dynamic data. And then, the operating system copies the collected data into the created bitmap to finish data collection. Furthermore, after the operating system finishes data acquisition, the bitmap is usually encoded and the encoded data is sent to the streaming media server through the client, so that the streaming media server decodes the encoded data and displays the data displayed in the Flash window to other users.

in the related art, when data is acquired, data displayed on a Flash window is rendered based on different rendering interfaces, for example, interfaces such as a Graphics Device Interface (GDI) and an Application Programming Interface (API), so that when an operating system acquires data, the operating system must acquire data rendered by using one rendering Interface by using an acquisition Interface matched with the rendering Interface. The collected data is then copied into the created bitmap.

Because different rendering interfaces are adopted to render data in the Flash window, different acquisition interfaces are required to acquire the data, so that the number of the interfaces required to be developed is large, and a large amount of manpower and material resources are consumed, so that the data acquisition mode is complex and tedious, the efficiency is not high, and the flexibility is poor.

Fig. 2 is a flowchart illustrating a data collection method according to an exemplary embodiment, where an execution subject of the data collection method is an operating system installed on a terminal, and at least one browser can run on the operating system, and the operating system includes a Flash control and a video collection component, and data collection is implemented through interaction between the Flash control and the video collection component. The video acquisition component is a component based on a browser interface (an ActiveX component interface is adopted by an IE system browser, and PPAPI interfaces are adopted by chord and Firefox system browsers). As shown in fig. 2, the data acquisition method includes the following steps.

In step 201, the Flash control calls a window handle preparation function of the video capture component through the scripting language, so that the video capture component prepares for searching a window handle of a target Flash window.

In the embodiment of the invention, the Flash control calls the function of the video acquisition component for preparing and searching the window handle through the script language so as to complete the initialization of the video acquisition component, so that the video acquisition component prepares all functions possibly involved in the data acquisition process and informs the video acquisition component to prepare for receiving the parameters to be sent by the Flash control.

In step 202, the Flash control sends the first width and height to the video capture component, and calls a process name obtaining function of the video capture component through the scripting language, so that the video capture component obtains a first name of a first process, calls a process enumeration function, enumerates a second process, and obtains a second name of the second process.

in the embodiment of the present invention, the process obtaining function may be a function GetModuleFileName, the process enumeration function may be a function createtolhelp 32Snapshot, the first process is a process where a window that needs data acquisition is located, and the second process is all processes running in the current operating system; the process name obtaining function can obtain a first name of a first process where a target Flash window is located according to the target Flash window selected by a user, and then the process enumeration function can enumerate a second process by checking all processes running in a current background. If there are more than one second process enumerated by the process enumeration function, a process name list may be maintained for the second process, and the second name of each process in the second process is stored in the process name list. The embodiment of the present invention does not specifically limit the types of the process acquisition function and the process enumeration function and the number of enumerated second processes.

in step 203, the video capture component invokes the first process determination function and the second process determination function, obtains a third process associated with the first name in the second name, and stores a process identifier of the third process in the process identifier list.

in the embodiment of the present invention, the First Process determination function may be a function Process32First, and the second Process determination function may be a function Process32 Next. For example, if the second name is stored in the process name list, the first process judgment function is called to match the first second name in the process name list with the first name; judging whether the first second name is associated with the first name or not; if the first second name is associated with the first name, acquiring a third process corresponding to the first second name, and storing a process identifier of the third process into a process identifier list; and if the first second name is not associated with the first name, skipping the first second name and not storing. And after the judgment of the first second name is finished, calling a second process judgment function to obtain the next second name in the window name list, and judging again until all the second names in the window name list are judged.

Note that, since the process names of different processes may be the same, for example, process 1, process 2, and process3 are from a series of products of a product line, such as a music box, a live room, and a personal space, respectively, where a indicates the name of the product line. The process names of the three processes are set to be the same, for example, named as x. Therefore, the process 1 is associated with the processes 2 and 3, that is, the name of one process is the same as that of the other process, that is, there is an association; in other words, in the embodiment of the present invention, if a second name is the same as the first name, it is determined that the second name is associated with the first name.

In step 204, the video capture component calls a first enumeration window function with the first callback function as a pointer to obtain all top-level windows existing in the current operating system, then obtains a first top-level window handle of the top-level window in the first callback function, and calls an identification function to obtain a first top-level process identification of the top-level window based on the first top-level window handle.

in this embodiment of the present invention, the first enumeration window function may be an engine windows function, and the identification function may be a getwindowthreadprocess id function. The first enumeration window function needs to acquire all top-level windows existing in the current operating system, and acquire first top-level window handles of all top-level windows in the first callback function; and then, taking the first top-level window handles as parameters, and calling an identification function to obtain a first top-level process identification of a process of the window corresponding to each first top-level window handle.

for example, if top-level windows existing in the current operating system are respectively a, B, C, and D, then the first top-level window handle of the obtained top-level window a is 0001, the first top-level window handle of the top-level window B is 0002, the first top-level window handle of the top-level window C is 0003, and the first top-level window handle of the top-level window D is 0004, the first top-level window handles 0001, 0002, 0003, and 0004 are respectively used as parameters to call the identification function to obtain the first top-level process identifiers of the top-level window a, the top-level window B, the top-level window C, and the top-level window D.

In step 205, the video capture component obtains a second top-level process identifier from the process identifier list based on the first top-level process identifier, obtains a second top-level window handle based on the second top-level process identifier, then calls a second enumeration window function with a second callback function as a pointer, and obtains a child window handle in the second callback function based on the second top-level window handle.

In this embodiment of the present invention, the second enumeration window function may be an enum child windows function, and the video capture component obtains all process identifiers in the process identifier list and compares all process identifiers with the first top-level process identifier. And if the first top-level process identifier is matched with a second top-level process identifier in all the process identifiers, acquiring a second top-level window handle corresponding to the second top-level process identifier. Wherein, the second top window identification can be one or more; thereafter, a top-level window handle list may be maintained for the second top-level window handle, and the resulting second top-level window handle saved to the top-level window handle list.

and the video component calls a second enumeration window function by taking the second callback function as a pointer and taking each top window handle in the top window handle list as a parameter, and acquires the child window handles of the child windows included in the top window corresponding to each top window handle in the second callback function until each top window handle in the top window handle list is traversed.

in step 206, the video capture component calls a window rectangle function to obtain a fourth width-height size of the sub-window handle, compares the fourth width-height size with the first width-height size, then obtains a fifth width-height size in the fourth width-height size, which is the same as the first width-height size, and uses the sub-window handle corresponding to the fifth width-height size as the first window handle.

In the embodiment of the present invention, the window rectangular function may be a function GetWindowRect, the video acquisition component calls the window rectangular function with the sub-window handle as a parameter, obtains a fourth width and height size of the sub-window corresponding to the sub-window handle, compares the fourth width and height size with the first width and height size sent by the Flash control, and uses the sub-window handle corresponding to the fourth width and height size which is the same as the first width and height size as the first window handle. The video capture component may then maintain a first list of candidate window handles for the first window handle and save the first window handle to the first list of candidate window handles. The number of the first window handles may be one or more, which is not specifically limited in this embodiment of the present invention.

in step 207, the Flash control sends the second width and height size to the video capture component, and calls the window rectangular function of the video component again through the scripting language, so that the video capture component compares the fourth width and height size with the second width and height size, then obtains a sixth width and height size in the fourth width and height size, which is the same as the second width and height size, and takes a sub-window handle corresponding to the sixth width and height size as the second window handle.

In the embodiment of the invention, the video acquisition component sends the notification message to the Flash control after the first window handle is searched, so that the Flash control knows that the video acquisition component has finished searching the first window handle. And then, the Flash control cuts the size of the Flash control according to the preset setting to generate a second width and height size, wherein the preset setting can be height increase, width increase, height decrease and width decrease, and the embodiment of the invention is not specifically limited in this respect.

the video capture component may maintain a second candidate window handle list for the second window handle and save the second window handle to the second candidate window handle list. The number of the second window handles may be one or more, which is not specifically limited in this embodiment of the present invention.

it should be noted that after the second window handle is searched, the video capture component sends a notification message to the Flash control again, so that the Flash control knows that the video capture component has finished searching the second window handle, and then the Flash control adjusts and restores the current second width-height size to the first width-height size to maintain the attributes of the Flash control.

in step 208, the Flash control calls an end search window handle function of the video acquisition component through the scripting language to compare the first window handle with the second window handle; if the same handle exists in the first window handle and the second window handle, the video acquisition component acquires a third width-height size of the target Flash window identified by the same handle, and executes the following step 209; and if the same handle does not exist in the first window handle and the second window handle, the video acquisition component generates a search failure notification message and sends the search failure notification message to the Flash control.

in the embodiment of the present invention, taking the above-mentioned maintaining of the first candidate window handle list and the second candidate window handle list as an example, each window handle in the first candidate window handle list is compared with each window handle in the second candidate window handle list; and if the same handle does not exist, the video acquisition component generates a search failure notification message, the notification mode of the message can be an event notification mode, and the search failure notification message is sent to the Flash control.

and the Flash control generates a failure prompt after receiving the search failure notification message, displays the failure prompt to the user, and provides the user with a contact way of the technical developer so that the user can contact the technical developer. It should be noted that, in the embodiment of the present invention, the failure probability of the video capture component in searching for the target Flash window is close to zero.

It should be noted that there is a possibility that the window sizes of the process windows are the same, and therefore, when searching for the first window handle, a plurality of window handles of the process windows having the same width and height as the first window handle may be found. The Flash control cuts the size of the Flash control, so that the first width and height size and the second width and height size which are sent to the video acquisition are different, and other windows with the same size as the Flash control cannot be changed at the same time, so that the same handle is the window handle of the target Flash window in the first window handle and the second window handle as long as the same handle exists.

in step 209, the video capture component creates a bitmap according to the third width and height dimensions, invokes a window capture function, copies the content displayed in the target Flash window, and pastes the content displayed in the target Flash window to the created bitmap to complete the data capture operation.

The window intercept function may be a PrintWindow function, and the type of the window intercept function is not specifically limited in the embodiment of the present invention. The video acquisition component creates a bitmap with the third width and height as parameters, and calls a window capture function to paste all contents displayed in the target Flash window into the created bitmap, and for the contents in the target Flash window copied by the video acquisition component, the contents can be dynamic contents or static contents.
