With the foregoing drawings in mind, certain embodiments of the disclosure have been shown and described in more detail below. These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In the embodiments of the present invention, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. In the description of the present invention, the character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Fig. 1 is a schematic view of an application scenario provided by an embodiment of the present invention, for example, as shown in fig. 1, the application scenario may include a video storage server and at least one video playing device. In order to improve the accuracy of a screenshot result when a user wants to intercept a certain image frame or video stream in a video resource while watching the video resource through a video playing device, an embodiment of the present invention provides a screenshot method, which is different from the prior art in that after receiving an input screenshot instruction for a currently played video resource, the video playing device does not recognize the screenshot instruction and perform a screenshot operation after recognizing the screenshot instruction, but first obtains an identifier of the video resource and a playing node of the video resource when receiving the screenshot instruction, and sends a data request including the identifier of the video resource and the playing node of the video resource to a video storage server, so that the video storage server intercepts at least one frame of target image associated with the playing node in the video resource according to the playing node, and sends the intercepted at least one frame of target image to the video playing device, because at least one frame of target image associated with the playing node is the image frame that the user wants to capture the image, the accuracy of the capture result obtained by the video playing device is effectively improved. In addition, in the process of executing the whole intercepting operation, for video playing, the intercepting operation is not required to be executed, and the intercepting result sent by the video storage server is received, so that the intercepting operation does not influence the continuous playing effect of the video resource, and the smoothness of continuous playing of the video resource is improved.
In the above description, when the video storage server performs the screen capture operation, at least one frame of target image associated with the play node in the video resource is captured according to the play node. For example, the number of the at least one frame of target images may be one, or may be multiple. When the number of the at least one frame of target image is one, the at least one frame of target image associated with the playing node can be understood as the target image frame corresponding to the playing node, that is, the video storage server intercepts the target image frame corresponding to the playing node in the video resource; when the number of the at least one frame of target image is multiple, the at least one frame of target image associated with the play node may be understood as multiple target image frames corresponding to the play time segment of the play node, that is, what is intercepted by the video storage server is a target video stream in the video resource that includes the play time segment of the play node.
For example, taking the playing node as the 5 th millisecond as an example, the at least one frame of target image associated with the 5 th millisecond may be understood as the one target image frame corresponding to the 5 th millisecond, that is, the video storage server intercepts the target image frame corresponding to the 5 th millisecond in the video resource; when the number of the at least one frame of target image is multiple, the at least one frame of target image associated with the 5 th millisecond may be understood as including multiple target image frames corresponding to the play time segment of the 5 th millisecond, that is, the video storage server intercepts a target video stream in the video resource, including the play time segment of the 5 th millisecond.
For example, the video playing device may be a television, a notebook computer, a tablet computer, or another terminal having a video playing function and a data interaction function with the video storage server, and here, the embodiment of the present invention is only described by taking the video playing device as a television, a notebook computer, or a tablet computer, but the embodiment of the present invention is not limited thereto.
The screen capture method provided by the embodiment of the present invention will be described in detail below by taking the number of at least one frame of target image as one, that is, the target image frame corresponding to the play node in the video resource is captured by the video storage server as an example. It can be understood that, when the number of the at least one frame of target image is plural, that is, the video storage server intercepts the video resource, the method of playing the video stream related to the node is similar to the method of playing the target image frame corresponding to the node in the video resource intercepted by the video storage server. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic flowchart of a screen capturing method according to an embodiment of the present invention, for example, please refer to fig. 2, where the screen capturing method may include:
s201, the video playing device receives an input screen capture instruction aiming at the currently played video resource.
The screen capture instruction may be a voice instruction input by a user, or a click or touch instruction input by the user on the screen, and may be specifically set according to actual needs, where the embodiment of the present invention does not further limit an input mode of the screen capture instruction.
For example, when the screen capture instruction is a voice instruction, in a possible manner, the user may input the voice instruction to the video playing device through an intelligent voice module of the video playing device itself; in another possible manner, a user may input the voice instruction to a device associated with the video playing device, and the device associated with the video playing device sends the voice instruction to the video playing device, for example, the device associated with the video playing device may be a remote controller of the video playing device, or a terminal device connected to the video playing device, such as a mobile phone, and the like.
Continuing to take the screen capture instruction as the voice instruction as an example, when the user watches the video resource, if the user wants to capture the image frame currently displayed by the video playing device, the user may input the voice screen capture instruction to the video playing device, for example, "please help me capture the current picture", correspondingly, after the video playing device receives the voice screen capture instruction, unlike in the prior art, the video playing device does not need to recognize the voice screen capture instruction, and does not need to execute the corresponding screen capture operation after re-recognition, but obtains the identifier of the video resource, and when receiving the voice screen capture instruction, the playing node of the video resource executes the following S202:
s202, the video playing device obtains the identification of the video resource and the playing node of the video resource when the screen capturing instruction is received.
For example, the identifier of the video resource may be a name of the video resource, or may also be a serial number of the video resource, as long as the video resource can be uniquely identified.
Taking a video resource as a piglet cookie and the identifier of the video resource is 'piglet cookie', when a video playing device receives a voice screen capture instruction 'please help me to capture the current picture' input by a user, the identifier 'piglet cookie' of the video resource piglet cookie is acquired, and when the video playing device receives the voice screen capture instruction 'please help me to capture the current picture', a playing node of the piglet cookie is played. Since the embodiment of the present invention is described by taking an example of capturing a certain image frame, the playing node herein may be understood as the playing time point of the piglet cookie being played, and assuming that the playing time point being played is the 10 th millisecond, the video playing device executes the following S203 after respectively acquiring the identifier "piglet cookie" of the piglet cookie as the video resource and the 10 th millisecond of the playing time point being played:
s203, the video playing device sends a data request to the video storage server.
The data request comprises an identifier of a video resource and a playing node of the video resource; the data request is used for requesting the video storage server to intercept a target image frame corresponding to the playing node in the video resource.
S204, the video storage server intercepts a target image frame corresponding to the playing node in the video resource.
With reference to the description in S202, after the video playing device sends the data request including the identifier "piglet cookie" of the piglet cookie as the video resource and the 10 th millisecond of the playing time point being played to the video storage server, correspondingly, the video storage server may find the video resource of the piglet cookie according to the identifier "piglet cookie" of the piglet cookie as the video resource, and then capture the target image frame corresponding to the 10 th millisecond in the video resource of the piglet cookie according to the 10 th millisecond of the playing time point, so as to obtain the screen capture result.
It can be seen that, in the embodiment of the present invention, when performing screen capturing, screen capturing is performed according to the 10 th millisecond of the playing time point at which the video resource is playing when the video playing device receives the voice screen capturing instruction "please help me to capture the current picture", and the image frame corresponding to the 10 th millisecond of the playing time point is the image frame that the user wants to capture the screen, so that the accuracy of the obtained screen capturing result can be effectively improved.
After intercepting the target image frame corresponding to the playing node in the video resource, the video storage server can send the target image frame to the video playing device.
S205, the video storage server sends a data response to the video playing device.
Wherein the data response includes the target image frame.
Correspondingly, after receiving the target image frame, the video playing device may store the target image frame, share the target image frame on its own social platform, or perform other operations, which is not limited in the embodiments of the present invention.
Therefore, in the embodiment of the present invention, after receiving an input screen capture instruction for a currently played video resource, a video playing device may first obtain an identifier of the video resource and a playing node of the video resource when receiving the screen capture instruction, and send a data request including the identifier of the video resource and the playing node of the video resource to a video storage server, so that the video storage server captures a target image corresponding to the playing node in the video resource according to the playing node, and sends the captured at least one frame of target image to the video playing device.
Optionally, after the video playing device obtains the target image frame corresponding to the playing node through the data response, the video playing device may further display the target image frame in a specific area of a display screen of the video playing device. The specific region may be a region designated by the user on the display screen according to a preference, or may be a region fixedly set in advance.
For example, when the video playing device displays the target image frame in a specific area of the display screen, in a possible manner, the target image frame may be directly displayed in the bottom area of the display screen; in another possible manner, the target image frame may be displayed in a bottom area of the display screen first, and after receiving the user operation instruction, the target image frame may be displayed in a larger area of the display screen, even in a full screen.
Based on the embodiment shown in fig. 2, after the video playing device acquires the intercepted target image frame, the video playing device may further display the target image frame in a specific area of the display screen, so that the user can view the target image frame. Further, the embodiment of the present invention may further display the data information associated with the target image frame on the basis of displaying the target image frame, so that the user may further acquire the data information associated with the target image frame, thereby providing a better service for the user. For example, please refer to fig. 3, where fig. 3 is a schematic flowchart of another screen capturing method according to an embodiment of the present invention, where the screen capturing method may include:
s301, the video playing device acquires data information associated with the target image frame.
The data information associated with the target image frame may be understood as data information associated with a certain article or person in the target image frame, or may also be understood as data information associated with a video resource where the target image frame is located, and may be specifically set according to actual needs.
For example, continuing with the example of the video resource being a pig peclet, assuming that the captured target image frame shows a pig configuration holding a painting book, the associated data information corresponding to the target image frame may be understood as data information associated with the painting book, for example, a related introduction of the painting book, etc.; the associated data information corresponding to the target image frame may also be understood as data information associated with a piglet peclet's video asset, e.g. a related introduction of the piglet peclet's video asset, such as show time, age suitable for viewing, etc.
After the data information associated with the target image frame is fully understood, how the video playback device acquires the data information associated with the target image frame will be described in detail below.
Optionally, in a possible implementation manner, after intercepting a target image frame, the video storage server may send a first content identification request including the target image frame to the content server; correspondingly, after receiving the first content identification request, the content identification server identifies a target image frame in the first content identification request, searches and acquires data information associated with the target image frame after identifying the target image frame, sends the data information associated with the target image frame to the video storage server after acquiring the data information associated with the target image frame, and forwards the data information to the video playing device through the video storage server, so that the video playing device acquires the data information associated with the target image frame.
It should be noted that, in the embodiment of the present invention, after the content identification server searches for and acquires the data information associated with the target image frame, the data information associated with the target image frame is forwarded to the video playback device through the video storage server, because it is considered that the content identification server is a third-party server under a normal condition, and in order to ensure the security of the data information received by the video playback device, the data information associated with the target image frame may be safely handled by the video storage server, so as to ensure that the data information finally received by the video playback device is the data information whose security meets the requirement.
Of course, if the security of the data is not considered, or it is determined that the data information sent by the content identification server is the data information with higher security, after the content identification server searches and obtains the data information associated with the target image frame, the content identification server may directly send the obtained data information associated with the target image frame to the video playing device without forwarding the data information associated with the target image frame to the video playing device through the video storage server, that is, another possible implementation manner is adopted.
In another possible implementation manner, after the video storage server intercepts the target image frame, different from the above manner, the video storage server not only sends the target image frame to the content recognition server, but also sends an identifier of the video playing device to the content recognition server, that is, sends a second content recognition request including the target image frame and the identifier of the video playing device to the content server, and correspondingly, after receiving the second content recognition request, the content recognition server recognizes the target image frame in the second content recognition request, and after recognizing the target image frame, searches and acquires data information associated with the target image frame, and after acquiring the data information associated with the target image frame, directly sends the acquired data information associated with the target image frame to the video playing device corresponding to the identifier of the video playing device according to the identifier of the video playing device, so that the video playing device can acquire the data information associated with the target image frame.
It can be seen that, in this possible implementation manner, after the content identification server searches for and acquires the data information associated with the target image frame, the content identification server directly sends the acquired data information associated with the target image frame to the video playing device without forwarding the data information through the video memory, so that the efficiency of the video playing device in acquiring the data information can be further improved.
It should be noted that, if the video playback device does not acquire the data information associated with the target image frame, the user may be prompted that the data information associated with the target image frame is not identified.
It is understood that, when the video playing apparatus acquires the data information associated with the target image frame, the two possible implementations are only described as examples, but the embodiment of the present invention is not limited thereto.
