Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
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 only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The screen capture method provided by the invention can be applied to a terminal. The terminal may be, but is not limited to, various personal computers, notebook computers, mobile phones, tablet computers, vehicle-mounted computers, and portable wearable devices. The terminal of the invention adopts a multi-core processor. The processor of the terminal may be at least one of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a Video Processing Unit (VPU), and the like.
The invention provides a screen capture method, which is specifically shown in figure 1 and comprises the following steps:
and S100, caching the video with the preset time length before the current playing position after receiving a screen capture starting instruction of a user.
And S200, decomposing the pictures sequenced according to the video playing time from the cache video, and reversely sequencing the picture sequence to generate a reverse playing sequence number.
And step S300, playing the pictures according to a preset playing speed through the reverse playing sequence number, and selecting the pictures needing screen capturing based on the currently played pictures for storing and sharing.
In the current mode of watching video and carrying out screen capture, a certain time difference exists between the time when a picture needing to be captured is seen and a screen capture button is pressed to issue a screen capture instruction and the time when the screen capture is carried out, so that the captured picture is not a picture required by a user. In order to solve the above problems, this embodiment provides a screen capture method, which mainly uses a method of caching a video forward, decoding the video into a picture, and playing the picture in a slow speed in a reverse direction, so that a picture that a user wants to capture the screen can be easily selected.
Specifically, in this embodiment, whether a user sends a screen capture instruction is monitored in real time, and when it is monitored that the user sends the screen capture instruction, whether the video screen capture is performed is judged, and if not, the video screen capture is performed normally; if so, stopping playing the current video and recording the current playing position of the video; the screen capturing instruction comprises a clicking operation, a sliding operation or other gestures on the touch screen, and can be set according to the needs of a user, and the setting is not limited here. The method includes the steps that when a user plays a video and performs screen capture, due to the fact that the video playing speed is high, the picture of the user needing screen capture lags behind the current video playing position, and when the video is cached and downloaded, if the cached and downloaded video is long, after the user sends a screen capture instruction, the user needs to wait for the video clip cache to finish downloading, the cached video needs to occupy a large memory, and if the cached and downloaded video is short, the user can find the picture of the user needing screen capture after downloading a plurality of video clips. Therefore, in this embodiment, the duration of the video to be downloaded is preset, after an instruction that the user needs to capture a screen is received, the current playing position is recorded, the video with the preset duration is downloaded forward with the recorded current playing position as a starting point, and the downloaded video is stored in the buffer area. If the current playing position of the video recorded by the intelligent terminal is 10min38s and the preset duration of video downloading is 3s, downloading the video cached in the storage area into a video clip of 10min35 s-10 min38 s.
Further, when a video is captured in the prior art, because the video is always in a dynamic playing state, if a capture instruction is issued again after the picture needing to be captured completely appears, the captured picture may be a picture which is transited from the current picture to the next frame picture; if the screen capture picture appears soon, a screen capture instruction is sent, the captured picture may be a picture which is transited from a previous frame picture to a current picture, and finally the captured picture is not clear enough, or other unnecessary contents such as advertisements or player borders are captured due to the fact that the video picture cannot be played in the whole screen. Therefore, in this embodiment, after the cached video with the predetermined duration is obtained, the cached video segment is decoded, and each frame of video data of the video segment is converted into each corresponding frame of picture data, so that a user can directly obtain a clear picture to be captured, for example, a 3-second video segment can be decoded each time, and each second video segment is composed of 2 frames of pictures, so that 6 frames of picture data can be obtained and collocated each time of decoding, and the conversion of the video data into the picture data in the prior art is not repeated here.
Further, after the video clip is divided into a series of pictures, in order to combine the video pictures into a complete video clip, in this embodiment, the divided pictures are initially sorted according to the sequence of the video playing time to generate a picture sequence, and if the video clip of 10min35s to 10min38s is intercepted by the intelligent terminal, the pictures of the frame corresponding to the video at the position of 10min35s are sequentially sorted, so that the sequence of each frame of picture is consistent with the sequence of the video clip, and a user plays the pictures just like playing the video.
Preferably, when the video is played and the screen is captured, the picture desired to be captured is generally not far around the currently played picture, and the picture desired to be captured can be obtained faster if the reverse search is started from the currently played position. Therefore, in this embodiment, the pictures are subjected to reverse sequencing according to the picture sequence generated after the pictures are subjected to the initialization sequencing according to the playing time sequence, and a reverse playing sequence number is generated, that is, the pictures are sequenced from the recorded current playing position, and are sequentially played according to the reverse playing sequence number. In addition, the playing speed of the picture when the picture is selected subsequently can be preset, the user only needs to send a screen capture instruction, the subsequent video can be automatically played according to the speed preset by the user after being decoded into the picture, and the video picture can be browsed in a manual mode if the user is unsatisfied with the preset playing speed, so that the use of the user is facilitated.
Further, if the picture playing speed is fast during screen capture when the picture is selected, after the user sees that the picture needing screen capture issues the screen capture instruction, the currently played picture is not the picture that the user needs screen capture, so in order to balance the speed of cache downloading and guarantee the fluency of playing, the playing speed of the picture is controlled during subsequent picture selection in the embodiment, and the playing speed of the picture during subsequent screen capture is lower than the playing speed of the video before the screen capture instruction is received. For example, assuming that the playing speed of the network video is N frames/second (preferably 24 frames/second), and the picture playing speed is set to M frames/second (preferably 2 frames/second) when the user selects a picture, since the video is decomposed into multiple frames of pictures, and the picture that the user wants to capture may exist in two adjacent frames of pictures at the same time, the user needs to further determine which frame of picture is the most suitable, so that the playing speed of the picture in this embodiment is slow and at least should be smaller than the playing speed of the video before receiving the capture instruction, so that the user can be provided with sufficient time to determine which picture is the most desirable content of the user, so as to more accurately locate the picture that wants to capture.
Further, when the intelligent terminal monitors that the user stops playing the video picture and selects the currently played picture, the intelligent terminal judges that the user finds the picture which the user wants to capture the screen, and the whole screen capture process is finished. Because the playing speed of the video pictures is less than that before the screen capture instruction is received, when a user sees a picture to be captured and issues the screen capture instruction, sufficient time can be provided for judging that the picture is the most suitable picture, and because each picture generates a reverse playing sequence number in advance, when the user sees the picture to be captured, the currently played picture can be directly selected as the screen capture picture to be stored and shared according to the playing sequence number of the currently played picture.
Further, since the time lag time is generally related to the hardware configuration of the system and the design of the capture logic in the system software, if a picture to be captured is captured by a relatively fixed download duration video, sometimes the current cached picture is played completely and the picture to be captured cannot be found yet, so that it is necessary to download the cached next video segment forward to continue searching, but if the previous cached video is played and the next video segment is decoded, the play waiting time between the two video segments is long, which results in a picture playing process that is not smooth. Therefore, in this embodiment, a dual-thread manner is adopted, that is, a main thread and a sub-thread are set, the main thread is used for playing the picture with the reverse play sequence number according to a preset speed, while the main thread plays the picture, the sub-thread is used for preparing a next segment of picture to be played in advance, and when it is detected that the picture playing of the main thread is finished, the prepared picture with the next reverse play sequence number is transmitted to the main thread to be played continuously, and the sub-thread continues to perform buffering and decoding on a next segment of video until a user finds a picture to be captured, so that the whole screen capturing process is finished. The specific step of preparing the next segment of picture to be played by the sub-thread is as described above, and is not described herein again.
Preferably, in this embodiment, in order to implement seamless connection of video picture playing, the next picture to be played is played continuously from the end position of the currently played picture. Specifically, after caching the video with the preset time before the current playing position, the mobile terminal records the end position of the current cached video, after the cached video picture starts playing, the mobile terminal continues to cache the video with the preset time forward from the recorded end position of the last cached video and codes the video to prepare the next picture to be played, and records the end position of the current cached video again until the user stops playing the picture and selects the picture to be captured, and the whole screen capturing process is ended, so that the next picture to be played and the current picture to be played are seamlessly connected. If the video clips from 10min38s to 10min35s are cached currently, the intelligent terminal records the ending position of the currently cached video clip at 10min35s, and the caching is continued from 10min35s when the video is cached next time.
In order to better understand the technology of the present invention, the present invention further provides a specific application example, as shown in fig. 2, which specifically includes the following steps.
And step 203, caching the video with the preset time length before the current playing position.
And step 204, decoding the cached video and decomposing the video into a series of pictures which are sequenced according to the video playing time.
And step 205, reversely ordering the picture sequence and generating a reverse play sequence number.
And step 206, playing the pictures in sequence according to the reverse playing sequence number.
And step 208, ending.
Based on the above embodiment, the present invention further provides an intelligent terminal, and a schematic block diagram thereof may be as shown in fig. 3. The intelligent terminal comprises a processor, a memory, a network interface, a display screen and a temperature sensor which are connected through a system bus. Wherein, the processor of the intelligent terminal is used for providing calculation and control capability. The memory of the intelligent terminal comprises a nonvolatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium. The network interface of the intelligent terminal is used for being connected and communicated with an external terminal through a network. The computer program is executed by a processor to implement a screen capture method. The display screen of the intelligent terminal can be a liquid crystal display screen or an electronic ink display screen, and the temperature sensor of the intelligent terminal is arranged inside the intelligent terminal in advance and used for detecting the current operating temperature of internal equipment.
It will be understood by those skilled in the art that the block diagram shown in fig. 3 is only a block diagram of a part of the structure related to the solution of the present invention, and does not constitute a limitation to the intelligent terminal to which the solution of the present invention is applied, and a specific intelligent terminal may include more or less components than those shown in the figure, or combine some components, or have a different arrangement of components.
In one embodiment, an intelligent terminal is provided, which includes a memory and a processor, the memory stores a computer program, and the processor can realize at least the following steps when executing the computer program:
receiving a screen capture instruction, and caching a video with a preset time length before the current playing position;
the picture sequence ordered according to the video playing time is decomposed from the cache video, and the picture sequence is reversely ordered to generate a reverse playing sequence number;
and playing the pictures according to a preset playing speed through the reverse playing sequence number, and selecting the pictures needing screen capturing based on the currently played pictures for storing and sharing.
In one embodiment, the processor, when executing the computer program, may further implement: presetting the duration of a cache video and the playing speed of a picture when the picture is selected subsequently; monitoring whether a user sends a screen capture instruction in real time, judging whether the video screen capture is performed when the screen capture instruction sent by the user is monitored, and if not, performing normal screen capture; if so, stopping playing the current video and recording the current playing position of the video. And downloading the video with the recorded current playing position as a starting point forward for a preset time, and storing the downloaded video into a buffer area. Specifically, after an instruction that a user needs to capture a screen is received, the current playing position is recorded, a preset video with a preset duration is downloaded forwards by taking the recorded current playing position as a starting point, and the downloaded video is stored in the buffer area. If the current playing position of the video recorded by the intelligent terminal is 10min38s and the preset duration of video downloading is 3s, downloading the video cached in the storage area into a video clip of 10min35 s-10 min38 s.
In one embodiment, the processor, when executing the computer program, may further implement: after the buffered video with the preset duration is obtained, decoding the buffered video segment, and converting each frame of video data of the video segment into each corresponding frame of picture data; carrying out initial sequencing on the decomposed pictures according to the sequence of video playing time; the pictures with the initial sequence numbers are reversely sequenced to generate reverse playing sequence numbers, and the pictures are sequentially played according to the reverse playing sequence numbers; and monitoring the playing condition of the video picture and the operation of the user in real time, judging that the user finds the video picture to be intercepted when the video picture is monitored to stop playing and the user selects the currently played picture, and ending the whole screen intercepting process. Specifically, in this embodiment, after the pictures are initially sorted according to the playing time sequence, the initially sorted pictures are reversely sorted, so as to generate a reverse playing sequence number, that is, the pictures are sorted from the recorded current playing position, and are sequentially played according to the reverse playing sequence number. In addition, the playing speed of the picture when the picture is selected subsequently can be preset, the user only needs to send a screen capture instruction, the subsequent video can be automatically played according to the speed preset by the user after being decoded into the picture, and the video picture can be browsed in a manual mode if the user is unsatisfied with the preset playing speed, so that the use of the user is facilitated.
If the picture playing speed is high during screen capture when the picture is selected, after the user sees the picture to be captured and issues a screen capture instruction, the currently played picture is not the picture to be captured by the user, so that in order to balance the speed of cache downloading and guarantee the fluency of playing, the playing speed of the picture is controlled during subsequent picture selection in the embodiment, and the playing speed of the picture during subsequent screen capture is lower than the playing speed of the video before the screen capture instruction is received. For example, assuming that the playing speed of the network video is N frames/second (preferably 24 frames/second), and the picture playing speed is set to M frames/second (preferably 2 frames/second) when the user selects a picture, since the video is decomposed into multiple frames of pictures, and the picture that the user wants to capture may exist in two adjacent frames of pictures at the same time, the user needs to further determine which frame of picture is the most suitable, so that the playing speed of the picture in this embodiment is slow and at least should be smaller than the playing speed of the video before receiving the capture instruction, so that the user can be provided with sufficient time to determine which picture is the most desirable content of the user, so as to more accurately locate the picture that wants to capture.
In one embodiment, the processor, when executing the computer program, may further implement: presetting a main thread and a sub-thread, playing and downloading a video picture in a double-thread mode, wherein the main thread is used for playing a picture with a reverse playing sequence number according to a preset speed, the sub-thread is used for preparing a next picture to be played while the main thread plays each picture, and when the main thread detects that the picture playing of the main thread is finished, the prepared picture with the next reverse playing sequence number is transmitted to the main thread to be played continuously, and the sub-thread starts to buffer and decode the next video from the end position of the last cached video until a user finds the picture to be intercepted, so that the whole screen capturing process is finished.
