Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
With the development of network technology and multimedia technology, more and more users adopt electronic devices to play videos. Generally, when a user plays a video on an electronic device, the electronic device displays the video stream on a display window of the electronic device according to a fixed video stream preset or default by the user for the user to watch. When a user zooms and adjusts the display window, the size of the display window changes, and when the fixed video stream is in the adjusted display window, the displayed resolution is not favorable for viewing, and the viewing experience of the user is influenced.
The inventor finds that when a user resizes a display window, no matter whether the display window is reduced or enlarged, the fixed video stream display causes some problems, for example, when the display window is reduced, the total amount of pixels provided by the fixed video stream is not changed, but the size of the display window is reduced, so that the resolution of the adjusted display window is increased, the adjusted display window may not display the whole image, and the resolution required by the reduced window can clearly display the video image under the condition of reduction, and because the video stream is fixed, the code stream and the bandwidth requirement of the transmission video stream are not reduced, and the transmission bandwidth resource is wasted. For example, when the display window is enlarged, the total amount of pixels provided by the fixed video stream is unchanged, and the size of the display window is increased, so that the resolution of the adjusted display window is reduced, and it is difficult to restore the real video image under the condition of lower resolution, which causes that the user cannot clearly watch the video, and reduces the watching experience of the user.
In view of the above technical problems, the inventors have found through long-term research and provide a method, an apparatus, an electronic device, and a storage medium for adjusting video definition according to the present application, and when a user performs a zoom adjustment operation on a display window, obtain a target resolution corresponding to the adjusted display window, where the target resolution is convenient for the user to view a video, obtain a target bit rate of a video stream corresponding to the target resolution, play the target video stream at the target resolution, and display the target video stream, so that a better viewing effect can be obtained, and viewing experience of the user is improved.
For convenience of understanding, this embodiment shows a possible implementation manner of the video sharpness adjustment system, and fig. 1 shows an application environment schematic diagram of the video sharpness adjustment system according to the embodiment of the present application, please refer to fig. 1, where the video sharpness adjustment system 100 includes an electronic device 110 and a server 120, and the electronic device 110 is connected to the server 120. The server 120 sends a video stream to the electronic device 110 for display, where the video stream may be a live video stream, a video stream of an opposite user in a video call with the user, or a video stream of a user watching a tv show, a movie, or a short video online.
Fig. 2 is a schematic flow chart illustrating a method for adjusting video definition according to an embodiment of the present application, where when a user performs zoom adjustment on a display window, a target video stream is obtained, and the target video stream is displayed at a target resolution, so that a better viewing effect can be obtained, and viewing experience of the user is improved. In a specific embodiment, the method for adjusting video definition is applied to the electronic device 110 shown in fig. 1, the device 200 for adjusting video definition shown in fig. 10, and the electronic device 300 (fig. 11) equipped with the device 200 for adjusting video definition. The following will describe a specific flow of the embodiment by taking the electronic device 110 as an example, but it is understood that the electronic device applied in the embodiment may be a mobile phone, a tablet computer, a desktop computer, a notebook computer, a projection device, and the like, and is not limited herein. As will be described in detail with respect to the flow shown in fig. 2, the method for adjusting video definition may specifically include the following steps:
step S110, detecting a zoom adjustment operation on the display window.
When the display window plays a video in an initial video stream, when a user needs to perform zoom adjustment operation on the display window according to a watching requirement, the user can directly perform zoom adjustment operation on the display screen of the electronic device, the zoom operation can be operations such as clicking, touching, dragging and sliding on the display screen, and can also be operations performed through external equipment, such as clicking and sliding through a mouse, and then performing input operation through a keyboard and a remote controller, and the electronic device can detect the zoom adjustment operation of the display window in real time and timely acquire the zoom requirement of the user.
When the electronic device does not detect the zooming operation of the user on the display window, it indicates that the user does not need to zoom and adjust the display window, and the electronic device continues to acquire an initial video stream to play at the adjusted display window, wherein the initial video stream is a video stream preset by the user, a video stream default by the system, or a video stream adjusted by the user before.
Step S120, when the zoom adjustment operation on the display window is detected, obtaining a target resolution corresponding to the adjusted display window, where the target resolution is obtained based on the current zoom level of the display window and the current resolution of the adjusted display window.
When the zoom adjustment operation on the display window is detected, it is indicated that the user has a zoom requirement, and the size of the display window is adjusted according to the zoom adjustment operation of the user. When the user adjusts the display window, the user may adjust the display window several times, and the adjustment is attempted to the size desired by the user. Presetting a preset time interval, judging whether a new zooming operation is received after the preset time interval of the current zooming operation (namely the current zooming operation, namely the latest zooming operation), and if the new zooming operation is received, namely the time interval between two adjacent zooming operations is smaller than the preset time interval, indicating that the current zooming operation is not finished; and when a new zooming and adjusting operation is not received, the zooming and adjusting of the current round is finished, and the display window adjusted by the current zooming and adjusting operation is used as the adjusted display window. And taking one round of zoom adjustment as an adjustment unit, and taking the display window adjusted by the last zoom adjustment operation in the round of zoom adjustment as the adjusted display window, so that the problem that a user needs to frequently switch video streams after each adjustment is avoided, and the reduction of user experience and the waste of processor resources are avoided.
For example, the preset time interval may be 10 seconds, and the user performs two zoom adjustment operations, i.e., a first zoom adjustment operation and a second zoom adjustment operation, in a certain round of zoom adjustment. When the user performs the first zoom adjustment, namely the first zoom adjustment operation, and performs the second zoom adjustment, namely the second zoom adjustment operation, after 3 seconds, since the time interval between the first zoom adjustment and the second zoom adjustment is less than the preset time interval of 10 seconds, the zoom adjustment of the current round is still continued, and when the zoom adjustment operation of the user is not received again after the preset time interval of 10 seconds after the second zoom adjustment, the display window after the second zoom adjustment operation is considered as the adjusted display window.
The total amount of pixels provided by the initial video stream may be displayed with good resolution when displayed on the display window before adjustment, it being understood that the initial video stream is suitable for use in the display window before adjustment. Because the total amount of pixels provided by the initial video stream is not changed, and the size of the display window is changed, the pixels provided by the initial video stream are still used for displaying, the obtained current resolution is changed, and the displayed video picture may be blurred, so that the initial video stream is not suitable for the adjusted display window any more. And obtaining the target resolution according to the current zoom level of the display window and the adjusted current resolution of the display window, and obtaining a clearer viewing effect by displaying at the target resolution.
The zoom level may control a display scale of the video image in the display window, where the zoom level is positively correlated with the display scale, and when the zoom level is larger, the display scale is larger, and conversely, when the zoom level is smaller, the display scale is smaller, for example, when the zoom level is 100%, the video image is displayed in an original size, and when the zoom level is 200%, the video image is displayed after being enlarged by 2 times. Unlike the current resolution, the zoom level does not change with the zoom of the display window. The current zoom level is the zoom level of the adjusted display window, and since the zoom level does not change with the zoom of the display window, if the user does not adjust the zoom level, the current zoom level is the same as the zoom level of the display window before adjustment.
And step S130, acquiring the target bit rate of the video stream corresponding to the target resolution.
And acquiring a target bit rate of the video stream corresponding to the target resolution, wherein the video stream corresponding to the target bit rate can display video images more clearly.
When the zoom adjustment operation is an operation of enlarging the display window, the acquired target bit rate becomes large, so that details of the transmitted video image are increased, and the user has a good viewing experience. When the zoom adjustment operation is an operation of reducing the display window, the acquired target bit rate becomes small, so that details of the transmitted video image become small, the target bit rate adapts to the reduced display window, and the bandwidth resource can also be saved.
Step S140, obtaining a target video stream at the target bit rate, and displaying the target video stream at the target resolution in the adjusted display window.
And acquiring the target video stream at the target bit rate, wherein the acquired target video stream is adapted to the adjusted display window, and compared with the method that the initial video stream is displayed in the current resolution ratio in the adjusted display window, the target video stream is displayed in the target resolution ratio in the adjusted display window, so that a clearer video image can be displayed.
According to the method, the device, the electronic device and the storage medium for adjusting the video definition, the electronic device detects zoom adjustment operation on a display window, and when the zoom adjustment operation on the display window is detected, a target resolution corresponding to the adjusted display window is obtained, wherein the target resolution is obtained based on a current zoom level of the display window and a current resolution of the adjusted display window.
On the basis of the previous embodiment, the present application provides a method for adjusting video definition, which is used to obtain a target resolution matched with an adjusted display window, fig. 3 shows a flow diagram of a method for adjusting video definition according to another embodiment of the present application, please refer to fig. 3, where the method for adjusting video definition specifically includes the following steps:
and step S210, detecting the zooming adjustment operation of the display window.
For detailed description of step S210, please refer to step S110, which is not described herein again.
Step S220, when the zoom adjustment operation on the display window is detected, acquiring the current zoom level and the current resolution.
The current zoom level is the zoom level of the adjusted display window, and is used for representing the display scale of the video image in the adjusted display window. Since the zoom level does not change with the zoom of the display window, if the user does not adjust the zoom level, the current zoom level is the same as the zoom level of the display window before adjustment.
And the current resolution is the resolution corresponding to the adjusted display window, and the resolution of the initial media stream is also displayed for the adjusted display window. Since the total amount of pixels provided by the initial video stream is not changed and the size of the display window is changed, the pixels provided by the initial video stream are still used for displaying, the obtained current resolution is changed, and the displayed video picture may be blurred, so that the initial video stream is no longer suitable for the adjusted display window.
Step S230, determining the current zoom level and the target resolution corresponding to the current resolution based on a first preset mapping relationship, where the first preset mapping relationship at least includes a corresponding relationship among the current zoom level, the current resolution, and the target resolution.
Optionally, the first preset mapping relationship may be a relationship mapping table.
And determining the current zoom level and the target resolution corresponding to the current resolution based on the first preset mapping relation, and displaying the target resolution to obtain a clearer viewing effect.
And step S240, acquiring the target bit rate of the video stream corresponding to the target resolution.
And step S250, acquiring a target video stream at the target bit rate, and displaying the target video stream at the target resolution in the adjusted display window.
For detailed description of steps S240 to S250, please refer to steps S130 to S140, which are not described herein again.
In this embodiment, when the adjusted display window displays an initial video stream, a video image cannot be clearly displayed at a current resolution, the current resolution and a current zoom level are first obtained, then, based on a first preset mapping relationship, a target resolution corresponding to the current zoom level and the current resolution is determined, then, a target bit rate of the video stream corresponding to the target resolution is obtained, a target video stream is obtained at the target bit rate, and the target video stream is displayed at the target resolution in the display window after a season, so that a clear display effect can be obtained.
In this embodiment, on the basis of the foregoing embodiment, a method for adjusting video definition is provided, where a target resolution is adjusted according to a difference between a size of a window before zooming and a size of a window after zooming, so as to obtain a better video image playing effect, fig. 4 shows a flowchart of a method for adjusting video definition according to another embodiment of the present application, and please refer to fig. 4, where the method for adjusting video definition specifically includes the following steps:
step S310, the zoom adjustment operation of the display window is detected.
For detailed description of step S310, please refer to step S110, which is not described herein again.
Step S320, when the zoom adjustment operation on the display window is detected, obtaining an actual zoom value of the display window, where the actual zoom value is a difference between the size of the display window after zooming and the size of the display window before zooming.
When the zoom adjustment operation on the display window is detected, the size of the display window before zooming and the size of the display window after zooming are obtained, and then the difference between the size of the display window after zooming and the size of the display window before zooming is calculated and is used as the actual zoom value of the display window, and it can be understood that the actual zoom value is the actual zoom size or length.
In some embodiments, when the user performs zoom adjustment by merely adjusting the long side or the wide side of the display window, the size of the display window may be the length of the long side or the length of the wide side of the display window. For example, if the user performs zoom adjustment by adjusting the long side of the display window, and the size of the display window is the length of the long side of the display window, the length of the long side of the display window before zooming is acquired, the length of the long side of the display window after zooming is acquired, and the difference between the length of the long side of the display window after zooming and the length of the long side of the display window before zooming is calculated to obtain the actual zoom value.
In other embodiments, the size of the display window may be the length of the diagonal of the display window when the user's zoom adjustment adjusts the long side and the wide side of the display window. And obtaining an actual zooming value according to the difference between the length of the diagonal line of the zoomed display window and the length of the diagonal line of the display window before zooming.
And S330, when the actual zoom value is larger than a preset zoom value, acquiring the target resolution corresponding to the adjusted display window.
The preset zooming value is a critical value between the clearness and the unsharpness of the video content displayed by the display window after zooming adjustment.
The user carries out zoom adjustment operation on the display window, when the actual zoom value is smaller than the preset zoom value, the actual zoom value is smaller, namely the size change of the display window before and after zoom adjustment is smaller, the resolution change before and after zoom adjustment is smaller, the user can not perceive the change by naked eyes, the adjusted display window can still play clearer video images, and the user is not influenced to watch the video images. In order to avoid the waste of bandwidth resources and processor resources caused by repeatedly adjusting the resolution, the adjusted display window is zoomed and the initial video stream is continuously played at the current resolution.
When the actual zoom value is greater than the preset value, it indicates that the actual zoom value is larger, that is, the size change of the display window before and after zoom adjustment is larger, the resolution change before and after zoom adjustment is also larger, and the user can perceive the change by naked eyes, which may affect the user to watch the video image.
And step S340, acquiring the target bit rate of the video stream corresponding to the target resolution.
And step S350, acquiring a target video stream at the target bit rate, and displaying the target video stream at the target resolution in the adjusted display window.
For the detailed description of steps S340 to S350, refer to steps S130 to S140, which are not described herein again.
In this embodiment, when a zoom adjustment operation on a display window is detected, an actual zoom value of the display window is obtained, and when the actual zoom value is greater than a preset zoom value, it indicates that the actual zoom value is larger, that is, a size change of the display window before and after the zoom adjustment is larger, a resolution change before and after the zoom adjustment is also larger, and a user can perceive the change by naked eyes, which may affect the user to watch a video image.
In this embodiment, on the basis of the foregoing embodiment, a method for adjusting video definition is provided, where a target resolution is adjusted according to a size of a window to obtain a better video image playing effect, and fig. 5 shows a flowchart of a method for adjusting video definition provided in another embodiment of the present application, and please refer to fig. 5, where the method for adjusting video definition specifically includes the following steps:
and step S410, detecting the zooming adjustment operation of the display window.
For detailed description of step S410, please refer to step S110, which is not described herein again.
Step S420, when the zoom adjustment operation on the display window is detected, obtaining the current window size of the adjusted display window.
When a zoom adjustment operation on the display window is detected, the adjusted current size of the display window is obtained, and in some embodiments, when a user performs zoom adjustment only by adjusting a long side or a wide side of the display window, the current window size may be the length of the long side or the length of the wide side of the adjusted display window.
In other embodiments, when the user's zoom adjustment adjusts the long side and the wide side of the display window, the current window size may be the length of the diagonal of the adjusted display window.
In order to determine how to adjust the resolution according to the current window size, in the present embodiment, a preset window size may be obtained in advance, where the preset window size is a critical value for controlling whether the video stream is adjusted or not.
In some embodiments, the preset window size may be set according to the manufacturer's experience.
In other embodiments, the preset window size may be obtained based on the mapping relationship, specifically, the current network condition and the processor performance of the electronic device are obtained first. And determining a preset window size corresponding to the current network condition and the processor performance based on a second preset mapping relation, wherein the second preset mapping relation at least comprises the corresponding relation among the current network condition, the processor performance and the preset window size. Optionally, the second preset mapping relationship may be a mapping table.
When the current window size is smaller than the preset window size, for example, in a scene in which the user reduces the display window, the user reduces the display window from being larger than the preset size to being smaller than the preset size.
In other embodiments, in a scenario where the user zooms out the display window, the display window before adjustment displays an initial video stream, the initial video stream corresponding to an initial bit rate, the initial bit rate being a higher bit rate. Since the user reduces the display window, the total amount of pixels provided by the initial video stream is not changed, and the display window is reduced, the resolution of the adjusted display window is increased, but the reduced display window does not need to display too many details, and the adjusted display window can be played at a lower bit rate in order to save bandwidth resources. The updated resolution corresponding to the adjusted display window is obtained, the updated bit rate corresponding to the updated resolution is obtained again, the updated video stream is obtained at the updated bit rate, and the updated video stream is displayed by the adjusted display window at the updated resolution. Wherein the updated bit rate is less than the initial bit rate.
And step S430, when the current window size is larger than a preset window size, acquiring the target resolution corresponding to the adjusted display window.
When the current window size is larger than the preset window size, for example, in a scene in which the user enlarges the display window, the user enlarges the display window from being smaller than the preset size to being larger than the preset size, and obtains a target resolution corresponding to the adjusted display window.
And step S440, acquiring a target bit rate of the video stream corresponding to the target resolution.
And step S450, acquiring a target video stream at the target bit rate, and displaying the target video stream at the target resolution in the adjusted display window.
For detailed description of steps S440 to S450, please refer to steps S130 to S140, which are not described herein again.
In this embodiment, when a user performs zoom adjustment operation on a display window, a current window size corresponding to the adjusted display window is obtained, when the current window size is larger than a preset window size, a target resolution corresponding to the adjusted display window is obtained, a target bit rate of a video stream corresponding to the target resolution is obtained, the target video stream is obtained at the target bit rate, and the target video stream is displayed at the adjusted display window at the target resolution, so that an enlarged display window can display a clear video image.
On the basis of the foregoing embodiment, this embodiment provides a method for adjusting video definition, when a user of an electronic device makes a video call, a display window of the electronic device includes two display areas, the two display areas are used for displaying the user and an opposite user respectively, and definition adjustment is performed according to a display area where the opposite user is located in the video call, fig. 6 shows a flow diagram of a method for adjusting video definition provided in yet another embodiment of the present application, please refer to fig. 6, where the method for adjusting video definition specifically includes the following steps:
step S510, detecting a zoom adjustment operation on the display window.
For detailed description of step S510, please refer to step S110, which is not described herein again.
Step S520, when the electronic device is in a video call mode and the zoom adjustment operation on the display window is detected, acquiring a video content displayed in an adjusted first display area, where the display window includes the first display area and a second display area, and an area of the first display area is larger than an area of the second display area.
When the electronic equipment is in a video call mode, a display window of the electronic equipment displays a user picture and an opposite user picture, wherein the user picture is locally collected by a camera of the electronic equipment, and the opposite user picture is an image displayed after a video stream acquired by the electronic equipment from a server.
Optionally, the display window of the electronic device includes at least two display areas, each display area displaying one participant participating in the video call, that is, at least two display areas are respectively used for displaying the user and the counterpart user participating in the video call. In the present embodiment, taking two participants of a video call, that is, a user and a counterpart user as an example, the display window includes the first display region 111 and the second display region 112 shown in fig. 7 to 9, and the area of the first display region 111 is larger than that of the second display region 112. As shown in fig. 7, when the first display area 111 displays the user a, the second display area 112 displays the opposite user B. Alternatively, when the first display area displays the opposite user, the second display area displays the user (not shown in the figure).
In the video call mode, a zoom adjustment operation of the display window by the user is detected, and optionally, the zoom adjustment operation may be a click operation on the first display area 111 or the second display area 112 shown in fig. 7. And then, video content of the first display area 111 is acquired, wherein the content displayed in the first display area may include the user or include the opposite user.
When the video content does not include a picture of the user of the opposite party in the video call, it can be understood that the video content includes the user, the first display area displays the user picture, and the second display area displays the picture of the user of the opposite party. And the opposite user displays in the second display area with smaller area, and the zoom size of the zoom adjustment on the second display area is smaller, so that the corresponding second target video stream is obtained at the current resolution, the second target video stream is displayed in the adjusted second display area at the current resolution, and the adjusted second display area can still play a clearer opposite user picture without influencing the live video broadcast of the user. In order to avoid the waste of bandwidth resources and processor resources caused by repeatedly adjusting the resolution, the second target video stream (i.e. the aforementioned initial video stream) is still played at the current resolution in the scaled and adjusted second display region.
Step S530, when the video content includes a picture of an opposite user in a video call, obtaining a first target resolution corresponding to the adjusted first display area.
As shown in fig. 8, the first display area 111 is switched from the display user a to the display opposite user B according to the touch and click operation of the user, and the video content includes a picture of the opposite user in the video call. Since the opposite user B is displayed in the first display region 111 with a larger area, and the influence of the zoom adjustment on the first display region 111 is larger, when the initial video stream including the opposite user B is displayed in the first display region 111, since the total amount of pixels provided by the initial video stream is not changed, and the display region of the initial video stream is switched from the second display region 112 with a smaller area to the first display region 111 with a larger area, as shown in fig. 8, the current pixels displaying the first display region 111 of the opposite user B are unclear, it is necessary to obtain the first target resolution corresponding to the adjusted first display region, and it can be understood that the adjusted first display region is displayed at the first target resolution, so that a good display effect can be obtained.
It should be noted that, in fig. 8, the picture of the user a is always clearly displayed on the second display area 112 through the picture locally captured by the camera of the electronic device.
And step S540, acquiring a first target bit rate of the video stream corresponding to the target resolution.
For detailed description of step S540, please refer to step S130, which is not described herein again.
