Wherein the second display area is different from the first display area. For example, the first display area may be a partial display area on the left side of the display screen, and the second display area may be a partial display area on the right side of the display screen. Alternatively, the first display region may be a partial display region on an upper side of the display screen, and the second display region may be a partial display region on a lower side of the display screen.

And 103, starting to play the video from the target video frame corresponding to the target acquisition position in the first display area.

The display device may determine a target video frame corresponding to the target capture location and then play the video starting from the target video frame.

To sum up, the embodiment of the present application provides a method for adjusting a video playing progress, where a display device can display a plurality of collecting positions of a camera when the camera collects a video while playing the video. Therefore, the user can conveniently execute selection operation on the plurality of acquisition positions, the display equipment can adjust the playing progress of the video based on the selection operation, and the flexibility of adjusting the playing progress is effectively improved.

In the embodiment of the application, the display device may receive a video to be played, which is sent by the acquisition device, and a plurality of acquisition positions where a camera of the acquisition device is located in the process of acquiring the video. Or, the display device may include a camera, and the display device may directly acquire the video to be played through the camera, and may acquire a plurality of acquisition positions where the camera is located in the process of acquiring the video.

In the following embodiments, a video to be played and a plurality of acquisition positions where the camera is located are acquired by the display device are taken as examples, and the method for adjusting the playing progress of the video provided by the embodiments of the present application is exemplarily described. The method can be applied to a display device, and the display device comprises a camera and a display screen. Referring to fig. 2, the method may include:

step 201, responding to a video acquisition instruction, and starting a camera to acquire a video.

The user may touch a video recording control of the display device. The display device can receive a video acquisition instruction triggered by the user touching the video recording control, and can respond to the video acquisition instruction to start the camera. The camera can periodically collect video frames according to a first sampling period after being started. Accordingly, the display device can acquire a video including a plurality of video frames acquired by the camera.

Each video frame corresponds to one frame acquisition time, and the frame acquisition times of any two video frames are different. The moment when the display device collects one video frame every other first sampling period is the frame collecting moment of the video frame, namely the interval of the frame collecting moments of two adjacent video frames is the first sampling period. The first sampling period may be pre-stored in the display device.

In an embodiment of the application, the display device may record a frame capture time of each of a plurality of video frames included in the video. For example, the display device may record a first correspondence of each of a plurality of video frames included in the video and a frame capture time of the video frame. The first correspondence may have recorded therein an identification of each video frame. The identification of the video frame may be a sequence number of the video frame in a plurality of video frames. Therefore, the display device can be ensured to quickly determine the target video frame corresponding to the target acquisition position.

For example, the display device may acquire the current time of each video frame and determine the current time as the frame capture time of the video frame.

By way of example, table 1 shows a first correspondence between video frames and frame capture instants of the video frames. Assuming that the identifier of the video frame is the serial number of the video frame, referring to table 1, it can be seen that the frame acquisition time of the first video frame (i.e. the video frame with the serial number of 1) acquired after the camera is started is 6:00:10.200, i.e. 6 hours (h), 0 minutes (min), 10 seconds(s), and 200 milliseconds (ms). The frame acquisition time of the video frame with sequence number 10 is 6:00:17.400, i.e. 6h 0min 17s 400 ms.

TABLE 1

Identification of video frames	Frame acquisition time
		1	6:00:10.200
2	6:00:11.000
		3	6:00:11.800
4	6:00:12.600
		…	…
9	6:00:16.600
		10	6:00:17.400
11	6:00:18.200
		12	6:00:19.000

Also, as can be seen from table 1, the frame capture time interval of any two adjacent video frames is 800 ms. I.e. the first sampling period is 800 ms.

Step 202, in the process of collecting the video, collecting the collecting positions where the cameras are located to obtain a plurality of collecting positions.

The display equipment is internally provided with a position acquisition assembly, and the display equipment can control the position acquisition assembly to periodically acquire the position of the camera according to a second sampling period in the process of acquiring videos by the camera, so that a plurality of acquisition positions are obtained, namely all acquisition positions of the camera in the process of acquiring the videos.

Each acquisition position corresponds to one position acquisition time, and the position acquisition times of any two acquisition positions are different. The moment when the display device collects one collection position every second sampling period is the position collection moment of the collection position, namely the position collection moments of two adjacent collection positions are the second sampling period. The second sampling period may be pre-stored by the display device.

The second acquisition period may be greater than or equal to the first acquisition period. That is, the interval between the position acquisition time of two adjacent acquisition positions may be greater than or equal to the frame acquisition time of two adjacent video frames. Accordingly, the number of capture positions acquired by the display device in a unit time may be less than or equal to the number of video frames acquired in the unit time. For example, the second sampling period is greater than the first acquisition period. The first sampling period may be on the order of milliseconds and the second acquisition period may be on the order of seconds.

Optionally, the position acquisition assembly may include: at least one of a Global Positioning System (GPS) component, a base station positioning component, and a wireless positioning component (e.g., a bluetooth positioning component). Each acquisition location at which a camera is located may refer to the geographic coordinates at which the camera is located, which may include longitude and latitude. Also, the display device may move during the process of capturing the video. Accordingly, at least two acquisition positions of the plurality of acquisition positions may be different.

In the embodiment of the application, in the process of acquiring videos by the camera, each acquisition position acquired by the position acquisition assembly can be recorded in the target position file by the display device. For example, the display device may sequentially record the acquired acquisition positions in the target position file according to the acquisition sequence of the acquisition positions. And after the video and the collection of the collection position are completed, the display device can also record a second corresponding relation between the video and a target position file corresponding to the video, so that after a playing instruction for the video is received subsequently, the target position file corresponding to the video can be determined based on the second corresponding relation, and a plurality of collection positions where the camera collects the video are read from the target position file. Wherein, the second corresponding relation records the file name of the video.

In this embodiment of the application, the display device may further record the position acquisition time of each acquisition position in the aforementioned target position file. Thus, the display device can be ensured to quickly determine the position acquisition time of the target acquisition position.

For example, it is assumed that the position acquisition time of each of the plurality of acquisition positions recorded by the display device is as shown in table 2. It can be seen from table 2 that the position acquisition time of the acquisition position (x1, y1) is 6:00:10.800, and the position acquisition time of the acquisition position (x6, y6) is 6:00: 15.800.

TABLE 2

Acquisition position	Time of position acquisition
		(x1,y1)	6:00:10.800
(x2,y2)	6:00:11.800
		(x3,y3)	6:00:12.800
…	…
		(x7,y7)	6:00:16.800
(x8,y8)	6:00:17.800
		(x9,y9)	6:00:18.800

As can be seen from table 2, the position acquisition times of any two adjacent acquisition positions are spaced by 1 s. That is, the second sampling period is 1 s.

In the embodiment of the present application, in the process of capturing a video by the camera, after the position capture component captures a first capture position (i.e. the capture position at the earliest position capture time), the display device may record and store a third corresponding relationship between the first capture position and a video frame (hereinafter referred to as a reference video frame) captured at the position capture time of the first capture position. That is, the frame capture instant of the reference video frame is the same as the position capture instant of the first capture position. Wherein, the third correspondence may record the identifier of the reference video frame.

Alternatively, the display device may record the third correspondence in the aforementioned target location file.

Step 203, responding to a playing instruction for the video, playing the video in a first display area of the display screen, and displaying a plurality of acquisition positions where the camera is located in the process of acquiring the video in a map interface of a second display area of the display screen.

The display device may be displayed with a play control for the video. The user can touch the playing control, and correspondingly, the display device can receive a playing instruction triggered by the user touching the playing control. Then, the display device may respond to the playing instruction, play the video in the first display area of the display screen of the display device, and display a plurality of acquisition positions where the camera is located in the process of acquiring the video in a map interface in the second display area of the display screen.

In an embodiment of the present application, the process of displaying the plurality of acquisition positions by the display device may include: and the display equipment responds to the playing instruction aiming at the video, and determines a target position file corresponding to the video based on the second corresponding relation between the video and the target position file. The display device can then read the plurality of capture locations from the target location file and display the plurality of capture locations in a map interface in a second display area of the display screen.

Optionally, in the process of playing the video in the first display area, the display device may further display a position mark point in a map interface in the second display area based on the playing progress of the video, where the position mark point is located at a capture position corresponding to a currently played video frame. Therefore, the user can quickly and intuitively know the position where the camera collects the video frame, and the user experience is improved.

The acquisition position corresponding to the currently played video frame may refer to: and the position acquisition time is the closest acquisition position to the frame acquisition time of the currently played video frame. For example, the capture position corresponding to the currently played video frame may be the capture position with the same position capture time as the frame capture time of the video frame.

As an alternative implementation, the play instruction may be used to instruct the display device to play the video from the beginning. Accordingly, the display device may, in response to a play instruction for a video, play the video starting from a first video frame of the video in a first display area of the display screen, display a plurality of capture positions in a map interface in a second display area of the display screen, and display a position mark point at the first capture position (i.e., the capture position with the earliest position capture time among the plurality of capture positions).

Illustratively, referring to fig. 3, the display screen includes a first display area a and a second display area B. As can be seen from fig. 3, the first display area a is located on the left side of the display screen and the second display area B is located on the right side of the display screen.

Assuming that the plurality of capturing positions acquired by the display device are the plurality of capturing positions shown in the foregoing table 2, the plurality of capturing positions that the display device can display in the map interface of the second display area B may be as shown in fig. 3. The positions a to i in fig. 3 correspond in sequence to the acquisition positions (x1, y1) to (x9, y9) in table 2.

As can be seen from fig. 3, the position marker point Z is located at position a, i.e., at the acquisition position (x1, y 1). In addition, as shown in fig. 3, a progress bar 01 is also displayed in the first display area a, and the current playing progress of the video is "0: 00:01/0:00: 09". The file name "VID 20210618_ 123" of the video and the total playing time period "0: 00: 09" of the video may also be displayed in the second display area B.

Or, if the display device records the third corresponding relationship between the first capture position and the reference video frame, the display device may respond to the play instruction for the video, play the video from the reference video frame in the first display area of the display screen, display the plurality of capture positions in the second display area of the display screen, and display the position mark point at the first capture position.

Since the second sampling period is greater than or equal to the first sampling period, in the process of acquiring the video, the display device may not acquire the acquisition position where the camera is located after acquiring the first video frame in the video. In this case, if the video is played from the first video frame of the video, the position of the position marker point is not synchronized with the first video frame, that is, the position capture time of the position marker point is not the closest to the frame capture time of the first video frame to be displayed. In the embodiment of the present application, after receiving the play instruction for the video, the display device may start playing the video from the reference video frame in the first display area, so that synchronization between the position of the position marker and the frame capture time of the displayed video frame may be ensured.

For example, assume that the sequence number of the video frame corresponding to the first capture position recorded by the display device is 3, that is, the camera captures the third video frame. The display device may begin playing video from the third video frame after receiving a play instruction instructing the display device to begin playing video from the beginning.

As another alternative implementation, the play instruction may be used to instruct the display device to play the video starting from the middle video frame of the video. Accordingly, the display device may play the video from the intermediate video frame in response to a play instruction for the video, display a plurality of capture positions in the second display area of the display screen, and display the position mark point at a capture position whose position capture time is closest to the frame capture time of the intermediate video frame.

According to the above description, when the display device starts playing a video in the first display area of the display screen from any video frame in the video, all the capturing positions of the camera in the process of capturing the video can be displayed in the second display area of the display screen.

Step 204, in response to the selection operation for the plurality of acquisition positions, determining a target acquisition position from the plurality of acquisition positions.

In an embodiment of the application, the user may select a target acquisition position from the plurality of acquisition positions displayed in the second display area. Accordingly, the display device may determine a target acquisition position from the plurality of acquisition positions in response to a user selection operation for the plurality of acquisition positions.

In an alternative implementation, the selection operation may be a touch operation for a target acquisition position in the plurality of acquisition positions. That is, the user may touch a target acquisition location of the plurality of acquisition locations. The display device may determine the target acquisition position in response to a touch operation for the target acquisition position.

For example, continuing with fig. 3, the user has touched position g, i.e., the acquisition position (x7, y 7). Accordingly, the display device may take the capturing position (x7, y7) as the target capturing position in response to a touch operation of the user with respect to the capturing position (x7, y 7).

In another alternative implementation, position mark points are displayed in the map interface. The selection operation may be a drag operation for the position marker. That is, the user may drag the position mark point. Correspondingly, the display device can respond to the dragging operation aiming at the position mark point, update the position of the position mark point, and determine the acquisition position closest to the position of the position mark point in the plurality of acquisition positions as the target acquisition position after detecting that the dragging operation is finished. For example, the display device may determine, as the target capturing position, a capturing position that is the same as a position where the position marker point is located, from among the plurality of capturing positions, after the dragging operation is ended.

Furthermore, a trajectory line formed by connecting the plurality of acquisition positions according to the sequence of the position acquisition time is displayed in the map interface. The display device may update the position of the position mark point on the trajectory line in response to the drag operation for the position mark point.

For example, referring to fig. 4, the user drags the position marker Z on the trajectory line S and drags the position marker Z to the position g, i.e., the acquisition position (x7, y 7). Accordingly, the display apparatus may determine that the position marking point Z is located at the acquisition position (x7, y7) when detecting the end of the drag operation, and then may determine the acquisition position (x7, y7) as the target acquisition position.

In yet another alternative implementation, the selection operation may be a voice operation. That is, the user may express a voice operation including the reference position, and the display device may collect the voice operation and perform voice recognition on the voice operation to obtain the reference position. Thereafter, the display device may determine a distance of each of the plurality of acquisition positions from the reference position, and determine, as the target acquisition position, an acquisition position of the plurality of acquisition positions whose distance from the reference position is less than a distance threshold. That is, the display device may determine a reference distance (i.e., a distance between the aforementioned acquisition position and the reference position) corresponding to each of the plurality of acquisition positions, and determine an acquisition position corresponding to a reference distance smaller than the distance threshold among the plurality of reference distances as the target acquisition position.

Wherein the distance threshold may be greater than a smallest reference distance of the plurality of reference distances and less than a next smallest reference distance of the plurality of reference distances.

Because the selection operation is a voice operation, that is, when the user needs to adjust the playing progress of the video, the user only needs to express the voice operation to adjust the playing progress of the video, so that the operation complexity of the user is effectively reduced, and the user experience is improved.

Optionally, if there are multiple candidate acquisition positions in the multiple acquisition positions whose distances from the reference position are smaller than the distance threshold, the display device may determine the position acquisition time of each candidate acquisition position. Then, the display device may determine, as the target acquisition position, an alternative acquisition position with the earliest position acquisition time among the plurality of alternative acquisition positions.

It should be noted that the voice operation expressed by the user may include a name of an area, and in this case, the display device may determine the position of the center point of the orthographic projection of the area on the map interface as the reference position recognized from the voice operation.

For example, referring to fig. 5, the reference position determined by the display device is position m, and the distance w1 between the acquisition position (x6, y6) (i.e., position f) and the position m among the plurality of acquisition positions is equal to the distance w2 between the acquisition position (x7, y7) (i.e., position g) and the position m. And both w1 and w2 are less than the distance threshold.

Assuming that the position acquisition timings of the acquisition positions (x6, y6) and (x7, y7) are as shown in table 2, since the position acquisition timing 6:00:15.800 of the acquisition position (x6, y6) is earlier than the position acquisition timing 6:00:16.800 of the acquisition position (x7, y7), the display device may determine the acquisition position (x6, y6) as the target acquisition position.

And step 205, starting to play the video from the target video frame corresponding to the target acquisition position in the first display area.

After the target acquisition position is determined, the display device may determine a target video frame corresponding to the target acquisition position, and start playing a video from the target video frame in the first display area. That is, the display device may retrieve a target video frame from a plurality of video frames included in the video based on the target capture position and play the video from the target video frame, thereby achieving an effect of adjusting the play progress of the video based on the capture position.

In this embodiment of the application, the display device may determine a position capture time of the target capture position first, and then may determine, as the target video frame, a video frame of the plurality of video frames included in the video, where the frame capture time is closest to the position capture time. For example, the frame capture instant of the target video frame may be the same as the position capture instant of the target capture position.

For example, assuming that the display device determines the position capture time of the target capture position to be 00:14.800, the frame capture time of a plurality of video frames included in the video is shown in table 1. Since, among the plurality of frame capture times shown in table 1, the frame capture time 00:15.000 is closest to the position capture time 00:14.800, and the sequence number of the video frame corresponding to the frame capture time 00:15.000 is 7, the display device may determine the video frame with the sequence number of 7 as the target video frame. Also, as shown in fig. 3 and 4, the display device may play the video from the video frame to adjust the play progress of the video.

In the related art, a video includes a plurality of video frames, and a watermark is drawn in each of the video frames. The watermark includes a location of a camera of the monitoring device at the time the video frame was captured. If a user needs the display device to start playing the video from a video frame acquired by the camera at the target position, the user can watch the video first to know the track of the video acquired by the camera from the multiple watermarks of the video. Then, the user can estimate the playing time corresponding to the target position based on the track and the total playing time of the video, and touch the progress bar of the video based on the playing time. Correspondingly, the display device can respond to the touch operation and start playing the video from the target video frame so as to adjust the playing progress of the video. However, in this manner, the efficiency of the display device adjusting the playing progress of the video is low, and due to the influence of manual errors, the accuracy of adjusting the playing progress of the video is easily low.

In the method provided by the embodiment of the application, when the display device plays the video frame in the first display area of the display screen, the display device displays a plurality of acquisition positions in the second display area. The display device can directly display a plurality of collecting positions where the camera collects the video, and does not need to manually know the collecting positions after watching the video, so that a user can quickly select a target collecting position, and the efficiency of adjusting the playing progress of the video by the display device can be ensured. In addition, according to the method provided by the embodiment of the application, the display device can automatically play the video from the target video frame corresponding to the target acquisition position after the target acquisition position is determined, and the playing time corresponding to the target acquisition position does not need to be manually estimated to adjust the playing progress of the video, so that the influence of manual errors can be avoided, and the adjustment precision of the playing progress of the video is ensured.

It should be noted that, the order of the steps of the method for adjusting the playing progress of the video provided by the embodiment of the present application may be appropriately adjusted, and the steps may also be increased or decreased according to the situation.
