Detailed Description

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. 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.

In order to solve the foregoing technical problems, embodiments of the present invention provide a video playing method, apparatus and device, where the method and apparatus may be applied to NVR, or may also be applied to other electronic devices such as a notebook computer and a desktop computer, and are not limited specifically. First, a video playing method provided by an embodiment of the present invention is described in detail below.

Fig. 1 is a schematic flowchart of a first process of a video playing method according to an embodiment of the present invention, including:

s101: and after detecting that the mouse pointer is positioned on the video progress bar, determining a video image corresponding to the position of the mouse pointer on the progress bar.

For example, assuming that the execution subject is a notebook computer, a desktop computer, or NVR, during playing a video image, a user may move or stop on the video progress bar by operating a mouse pointer with a mouse.

In one embodiment, determining a video image corresponding to the position of the mouse pointer on the progress bar may include: determining the position of the mouse pointer on the progress bar; determining time information of the video image corresponding to the position; reading a plurality of frames of video images with the time information as a starting point from a preset storage space.

For example, during playing a video image, the executing entity may detect whether the mouse pointer is located on the video progress bar in real time, and if the mouse pointer is located on the progress bar, the specific position of the mouse pointer may be further determined. The correspondence between each position on the progress bar and the time information of the video image may be determined in advance, and the time information of the video image may be determined according to the correspondence and the position of the mouse pointer on the progress bar.

Assuming that the execution subject is NVR, the time information may be a time when the frame of video image (video image corresponding to the position of the mouse pointer on the progress bar) is captured, for example, the frame of video image is captured at 10 am, 10 min and 20 sec on 3/1/2019, and the time information of the frame of video image is 10 am, 10 min and 20 sec on 3/1/2019. Alternatively, the time information may also be the time information of the frame of video image in the whole played video image, for example, if the playing duration of the whole played video image is one hour, the frame of video image is located at the 20 th minute and the 10 th second in the one hour, and the time information of the frame of video image is the 20 th minute and the 10 th second.

For NVR (network video recorder), it can receive and store video images sent by a network camera (IPC). For example, the NVR may store the received video image in its own hard disk, in which case, the "preset storage space" is the NVR own hard disk. After the time information of the video image corresponding to the position of the mouse pointer on the progress bar is determined, a plurality of frames of video images with the time information as a starting point can be read from a hard disk of the network hard disk video recorder.

Assuming that the execution subject is a computer, the time information may also be the time information of the frame video image (the video image corresponding to the position of the mouse pointer on the progress bar) in the whole played video image. For example, the playing duration of the whole video image is one hour, the frame video image is located at the 20 th minute and the 10 th second in the one hour, and the time information of the frame video image is the 20 th minute and the 10 th second.

For a computer, the video resource can be acquired through a network, and the video resource can also be stored locally; that is, the "preset storage space" may be a storage space in a local computer, or may be a storage space in a server that provides video resources in a network, and is not limited specifically. After the time information of the video image corresponding to the position of the mouse pointer on the progress bar is determined, the multi-frame video image with the time information as the starting point can be read from the preset storage space.

Or, in another embodiment, the position of the mouse pointer on the progress bar may also be determined; determining the time information of the video image corresponding to the position; and reading a frame of video image corresponding to the time information from a preset storage space.

In the above embodiment, a plurality of frames of video images are read from the preset storage space, and in the present embodiment, one frame of video image is read.

S102: a thumbnail of the determined video image is generated and presented.

For example, various open source tools may be used to generate the thumbnail, or the video image may be cropped or adjusted in resolution to obtain the thumbnail.

As described above, in one embodiment, the position of the mouse pointer on the progress bar and the time information of the video image corresponding to the position are determined, and the multi-frame video image with the time information as the starting point is read from the preset storage space; in this embodiment, S102 may include: and generating a thumbnail of the multi-frame video image.

In the above another embodiment, when one frame of video image is read from the preset storage space, a thumbnail of the one frame of video image is generated in S102.

For example, N frames of video images starting from the time information may be read from a preset storage space, and then a thumbnail of each frame of the N frames of video images may be generated, so that N thumbnails are generated. N may be a positive integer of 1, 2, 3, etc., and the specific numerical value is not limited.

For example, the thumbnail may be displayed on the right side of the mouse pointer, or the thumbnail may be displayed on the left side of the mouse pointer, or the thumbnail may be displayed above or below the mouse pointer, and the specific display position is not limited.

In one embodiment, the thumbnail may be superimposed in a menu layer on the currently playing video image.

Taking NVR as an example, the frames displayed by NVR during playing video may include two layers: the bottom layer is a video layer, the top layer is a menu layer, and the menu layer can comprise time information of video images, a video progress bar and the like. In this embodiment, the thumbnail is displayed in a menu layer in a superimposed manner.

S103: and after the preset operation aiming at the thumbnail is detected, playing the video image corresponding to the thumbnail.

In this embodiment, the user may operate the displayed thumbnail, for example, the operation may be a click operation, a continuous click operation, a sliding operation, and the like, which is not limited specifically. After the execution main body detects the operation, the playing progress can be adjusted to play the video image corresponding to the thumbnail.

As described above, in one embodiment, thumbnails of a plurality of frames of video images are generated, and assuming that a plurality of thumbnails are generated and a user clicks one of the thumbnails, a video image corresponding to the thumbnail clicked by the user may be played.

After S103, the execution main body may sequentially play video images subsequent to the video image corresponding to the thumbnail. Namely, the playing is continued according to the adjusted playing progress.

By applying the embodiment of the invention shown in fig. 1, after the mouse pointer is detected to be positioned on the video progress bar, the video image corresponding to the position of the mouse pointer on the progress bar is determined; generating a thumbnail of the determined video image, and displaying the thumbnail; after the preset operation aiming at the thumbnail is detected, playing a video image corresponding to the thumbnail; that is to say, in the scheme, if the user is not interested in the currently played video image, the mouse pointer can be moved to the video progress bar, so that the thumbnail of the video image corresponding to the position where the mouse pointer is located can be displayed, the user can conveniently know where the video image is the interested video image, and in addition, the user can play the video image corresponding to the thumbnail by operating the thumbnail; therefore, the scheme is beneficial to the user to quickly locate the video image in which the user is interested.

A specific implementation is described below by taking an execution subject as NVR as an example, as shown in fig. 2, fig. 2 is a second flowchart of a video playing method provided by an embodiment of the present invention, and the method includes:

s201: detecting whether a mouse pointer is positioned on a video progress bar; if not, the detection is continued, and if yes, S202 is executed.

For example, the NVR may receive and store the video image sent by the IPC, and may also play the stored video image. In the process of playing the video image by the NVR, a user can operate a mouse pointer to move or stop on the video progress bar through a mouse, and the NVR can detect whether the mouse pointer is located on the video progress bar in real time.

S202: and determining the position of the mouse pointer on the progress bar, and determining the time information of the video image corresponding to the position.

If the mouse pointer is located on the progress bar, the specific location of the mouse pointer may be further determined. The correspondence between each position on the progress bar and the time information of the video image may be determined in advance, and the time information of the video image may be determined according to the correspondence and the position of the mouse pointer on the progress bar.

The time information may be a time when the frame of video image (the video image corresponding to the position of the mouse pointer on the progress bar) is captured, for example, the frame of video image is captured at 10 am 10 min 20 s on 1 am of 3 month in 2019, and the time information of the frame of video image is 10 am 10 min 20 s on 1 am of 3 month in 2019. Alternatively, the time information may also be the time information of the frame of video image in the whole played video image, for example, if the playing duration of the whole played video image is one hour, the frame of video image is located at the 20 th minute and the 10 th second in the one hour, and the time information of the frame of video image is the 20 th minute and the 10 th second.

S203: from the NVR hard disk, a plurality of frames of video images starting from the time information are read.

As described above, the NVR can receive and store the video image transmitted by the IPC, and in one case, the NVR can store the received video image in its own hard disk, and in this case, it can read the multi-frame video image starting from the time information from the hard disk of the NVR.

S204: and generating a thumbnail of the multi-frame video image.

For example, various open source tools may be used to generate the thumbnail, or the video image may be cropped or adjusted in resolution to obtain the thumbnail.

For example, N frames of video images starting from the time information may be read from the NVR hard disk, and a thumbnail of each of the N frames of video images may be generated, so that N thumbnails are generated. N may be a positive integer of 1, 2, 3, etc., and the specific numerical value is not limited.

S205: the thumbnail is superimposed in a menu layer on the currently playing video image.

The frames displayed by the NVR during playing the video may include two layers: the bottom layer is a video layer, the top layer is a menu layer, and the menu layer can comprise time information of video images, a video progress bar and the like. In the embodiment shown in fig. 2, the thumbnail is displayed by being superimposed in the menu layer.

S206: and after the click operation aiming at the thumbnail is detected, playing the video image corresponding to the thumbnail.

After the NVR detects the clicking operation of the user on the thumbnail, the playing progress can be adjusted so as to play the video image corresponding to the thumbnail. In the above S204, thumbnails of multiple frames of video images are generated, and if a plurality of thumbnails are generated and a user clicks one of the thumbnails, a video image corresponding to the thumbnail clicked by the user may be played.

S207: and sequentially playing the video images after the video image corresponding to the thumbnail.

Namely, the playing is continued according to the adjusted playing progress.

By applying the embodiment of the invention shown in fig. 2, after the mouse pointer is detected to be positioned on the video progress bar, the video image corresponding to the position of the mouse pointer on the progress bar is determined; generating a thumbnail of the determined video image, and displaying the thumbnail; after the preset operation aiming at the thumbnail is detected, playing a video image corresponding to the thumbnail; that is to say, in the scheme, if the user is not interested in the currently played video image, the mouse pointer can be moved to the video progress bar, so that the thumbnail of the video image corresponding to the position where the mouse pointer is located can be displayed, the user can conveniently know where the video image is the interested video image, and in addition, the user can play the video image corresponding to the thumbnail by operating the thumbnail; therefore, the scheme is beneficial to the user to quickly locate the video image in which the user is interested.
