The application provides a method for recording computer pictures for classroom teaching, which is applied to a recording scene of classroom teaching, fig. 1 is a first flowchart of the method for recording computer pictures for classroom teaching in the embodiment of the application, and as shown in fig. 1, in an embodiment of the invention, the method for recording computer pictures for classroom teaching provided by the invention comprises the following steps:
step S101, after receiving a recording signal, triggering screen capture to obtain an initial picture, and recording initial recording time; it is easy to understand that when a user wants to record a computer picture, the user clicks a recording button, and after receiving a recording signal, the computer triggers screen capture to obtain a starting picture and records the starting recording time; fig. 2 is a schematic screen capture diagram of a start picture according to an embodiment of the present application, for example, in the embodiment, as shown in fig. 2, after receiving a recording signal, a screen capture is triggered and a start picture is obtained as "first section: math lesson "and record the start recording time as" 8 o 10 min 1 sec ".
Step S102, monitoring a control event of a computer, and recording the occurrence time of the control event when the control event occurs; for example, when the time at which the control event occurs is "9 o 'clock 1 min 1 sec", the time at which the control event occurs is recorded as "9 o' clock 1 min 1 sec". The control event may be one or more, for example, the control event may be one or more of a mouse input event, a touch input event, a keyboard input event, or a smart pen input event for monitoring a computer, which is not specifically limited herein;
step S103, if a new control event is not generated within a preset time after the current control event is generated, triggering screen capturing to obtain a screen capturing picture, and recording screen capturing time; for example, fig. 3 is a first schematic diagram of a screenshot obtained when a screenshot is triggered according to an embodiment of the present application, referring to fig. 3, in this embodiment, the preset time is 5 seconds, and if a new control event is not generated within 5 seconds after a current control event is generated, the screenshot is triggered, and the screenshot is obtained by "gaussian theorem", and the screenshot time is recorded as "8 o' clock 20 min 1 sec", although in other embodiments, the preset time may be set to other times according to user requirements, and is not specifically limited herein; in the embodiment, the storage space is small by intersecting with the previous mode of timed screen capture, for example, 24 pictures are generated every second by adopting the timed screen capture, and 86400 pictures are generated in 1 hour, however, in the mode of monitoring the control event of the computer in the embodiment, the recording file in 1 hour is usually between 15 and 30M, the storage space is greatly reduced, which is not only convenient for the normalized recording of classroom teaching, but also the embodiment intersects with the previous mode of timed screen capture, which leads to higher CPU occupancy of the computer, and can influence the use condition of the computer when the teacher gives lessons on a lower configuration computer. In addition, it is noted that the recording object of the present application is a computer screen, not a camera screen, and therefore, the recording can only be performed in an action-triggered manner (i.e., an action-triggered screen capture manner).
And step S104, generating a picture file according to a time axis, wherein the time axis comprises the initial recording time and each screen capture time, and the picture file comprises an initial picture and a plurality of screen capture pictures. Further, the picture file is stored in JPEG format or other format. It is easily understood that the time axis can be conveniently generated by a time recording device by those skilled in the art, and a detailed description thereof is omitted here.
In the technical scheme of the embodiment, the change of the computer picture is triggered by the operation of a teacher or a user on the computer, so that the mode of action-triggered screen capture is adopted, the screen capture of the computer picture is triggered when the teacher operates the computer, the recording of the occurrence time of important pictures and important pictures is realized, and finally, a picture file is generated according to a time axis.
To reduce memory space, in one embodiment, recording the time of occurrence of a control event when the control event occurs comprises:
the time of recording is modified to the time of occurrence of the most recent control event. For example, if at "1 o' clock 1 min 1 sec": the method comprises the steps that A is input through a keyboard, screen capture cannot be conducted at the moment, the occurrence time of a latest control event is recorded as 1 point and 1 minute and 1 second, if the occurrence time of the latest control event is 1 point and 1 minute and 2 seconds, B is input through the keyboard, screen capture cannot be conducted at the moment, the recorded time of 1 point and 1 minute and 1 second is modified into the occurrence time of the latest control event as 1 point and 1 minute and 2 seconds, if the occurrence time of the latest control event is 1 point and 1 minute and 3 seconds, a mouse moves to a position (50 and 50), screen capture cannot be conducted at the moment, the recorded time of 1 point and 1 minute and 2 seconds is modified into the occurrence time of the latest control event as 1 point and 1 minute and 3 seconds, and the like, and the examples are not given; it is easy to understand that the time to be recorded is modified to the time of occurrence of the latest control event every time a new event occurs, rather than recording the time of occurrence of an event every time, and thus, the storage space is small.
In order to remove a large amount of invalid repeated information, for example, when a teacher speaks a certain ppt all the time, there is almost no change in the computer screen, in some embodiments, if a new control event is not generated within a preset time after a current control event is generated, a screen capture is triggered to obtain a screen capture screen, and after the screen capture time is recorded, the method further includes:
and if no screen capture exists from the screen capture time to the preset overtime time, triggering the screen capture to obtain a screen capture picture, and recording the screen capture time. Therefore, the screen content containing the key content can be intercepted to the maximum extent, the data redundancy can be effectively reduced, and the storage space is reduced. It is easily understood by those skilled in the art that the preset time is less than the preset timeout time, for example, if the preset time is 5 seconds and the preset timeout time is 30 seconds, the preset time 5 seconds is less than the preset timeout time 30 seconds; the preset timeout time is set according to a user requirement, and is not specifically limited herein.
For ease of understanding, the following description is made: assuming that the preset time is 5 seconds, the preset timeout time is 30 seconds, if the "left mouse button down event" is detected at "1 o 1 min 9 seconds", since the preset time is not reached for 5 seconds, then no screen capture is performed at this time, and the latest control event occurrence time is modified to "1 o 1 min 9 seconds", if the "left mouse button up event" is detected at "1 o 1 min 10 seconds", similarly, since the preset time is not reached for 5 seconds, then no screen capture is performed at this time, and the latest control event occurrence time is modified to "1 o 1 min 10 seconds", no event occurs during the period from "1 o 1 min 10 seconds" to "1 o 1 min 15 seconds", that is, no control event has occurred from the latest control event occurrence time ("1 o 1 min 10 seconds") to the preset time ("1 o 1 min 15 seconds") for 5 seconds, the screen capture is triggered, and the latest control event occurrence time is cleared, modifying the latest screen capture time to be 1 point 1 minute 15 seconds, and after that, triggering no screen capture in the process from 1 point 1 minute 15 seconds to 1 point 1 minute 45 seconds, namely, triggering the screen capture and modifying the latest screen capture time to be 1 point 1 minute 45 seconds when the screen capture is not triggered from the latest screen capture time (1 point 1 minute 15 seconds) to the preset timeout time (1 point 1 minute 45 seconds) for 30 seconds.
For the convenience of backtracking play, in an embodiment, generating the picture file according to a time axis includes:
and enabling the starting picture and the plurality of screen capturing pictures to be positioned at the corresponding positions of the time axis. Therefore, technicians in the field can conveniently skip the corresponding time point by dragging the time axis through some existing software technologies or algorithms to play the screenshot, and certainly in some other embodiments, technicians can conveniently skip by using the computer picture as the node for previewing and click the corresponding computer picture to skip to the corresponding time node through some existing software technologies or algorithms to realize the backtracking play of the recorded content, which is not described herein any more.
In one embodiment, the control events include one or more combinations of mouse events, keyboard events, and PPT remote control flipper events. For example, in this embodiment, the control event is a mouse event, the mouse event of the computer is monitored, and when the mouse event is ended, the screen capture is triggered to obtain a screen capture image, and the screen capture time is recorded.
To facilitate synchronized recording of sound, in one embodiment, after receiving the recording signal, the method further comprises:
and when the initial picture and the plurality of screen capture pictures are positioned at the corresponding positions of the time axis, corresponding audio information played by a computer sound pick-up is collected, and the audio information is stored in an MP3 format. In this embodiment, the computer sound pickup is a sound pickup arranged on a computer, and certainly, in some other embodiments, in order to improve the recording quality, a separate sound pickup with high configuration may be arranged, which is not specifically limited herein.
For less storage space, in one embodiment, before storing the audio information in MP3 format, the method further comprises:
and reducing the recorded code stream for the collected audio information. For example, when recording, the processing of the recorded code stream is reduced for the collected audio information, so that a smaller audio file is output, for example, the code stream set by the audio file is 32 k.
In order to record the electronic whiteboard information while recording the computer image, in an embodiment, after receiving the recording signal, the method further includes:
when the collected initial picture and the plurality of screen capturing pictures are located at the positions corresponding to the time axis, the collected touch data information is recorded through the electronic whiteboard, and the touch data information is stored in a text format, so that the recorded information can be conveniently watched at the later stage. In this embodiment, the text format is json, but in some other embodiments, xml, csv or a proprietary format may also be used, which is not specifically limited herein.
