Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
Fig. 1 is a flowchart of a video playing method provided in some embodiments of the present disclosure, where the video playing method shown in fig. 1 may be executed by an electronic device having video processing capability and employing a touch display screen as an output display screen; an electronic device may exemplarily be understood as a device such as a smartphone, a tablet computer, etc.
As shown in fig. 1, a video playing method provided by some embodiments of the present disclosure includes steps S101 to S103.
Step S101: the method comprises the steps of obtaining the video resolution of a video to be played and obtaining the screen resolution of a touch display screen in the electronic equipment.
The video resolution of the video to be played refers to the image resolution of a video frame in the video to be played, and the video resolution includes a horizontal resolution in a horizontal direction and a vertical resolution in a vertical direction.
In some embodiments of the present disclosure, the method for obtaining the video resolution of the video to be played includes the following steps. 1, if the video to be played is a video file stored in a local memory, determining the video resolution of the video to be played by reading the header file information of the video file. 2, if the video to be played is a video stream sent by the server, the video resolution of the video to be played can be determined by analyzing the metadata of the video stream. It should be noted that the method for obtaining the video resolution of the video to be played is not limited to the foregoing example, and other methods known in the art may also be used to obtain the video resolution of the video to be played.
The screen resolution of the touch display screen also includes a lateral resolution in the lateral direction and a longitudinal resolution in the longitudinal direction. In some embodiments of the present disclosure, the screen resolution of the touch display screen may be obtained by reading a touch display screen attribute configuration file of the electronic device.
Step S102: and determining the canvas resolution of the display canvas according to the video resolution and the screen resolution.
The display canvas is a canvas for carrying a video to be played. In some embodiments of the present disclosure, the canvas resolution of the display canvas is a maximum resolution of the non-deformation output of the video to be played when the video to be played is played by using the touch display screen.
In some embodiments of the present disclosure, determining the canvas resolution of the display canvas based on the video resolution and the screen resolution may be performed as follows.
First, a lateral resolution and a longitudinal resolution in a video resolution are acquired, and a lateral resolution and a longitudinal resolution in a screen resolution are acquired.
Then, comparing the transverse resolution of the video resolution with the transverse resolution of the screen resolution to obtain a transverse scaling ratio; and comparing the vertical resolution of the video resolution with the vertical resolution of the screen resolution to obtain a vertical scaling ratio.
Then, the larger value of the lateral resolution and the longitudinal resolution is selected as the actual scaling ratio.
Finally, the canvas resolution is determined by adopting the actual scaling ratio and the horizontal resolution and the vertical resolution in the video resolution.
For example, in one particular application of the embodiments of the present disclosure: the video resolution of a video to be played is 800 × 600, wherein 800 is the transverse resolution and 600 is the longitudinal resolution; the screen resolution of the touch display screen is 1920 × 1080, where 1920 is the horizontal resolution and 1080 is the vertical resolution. The lateral scaling ratio obtained from the two lateral resolutions is 0.417 and the longitudinal scaling ratio obtained from the two longitudinal resolutions is 0.556. Selecting a numerical value with a larger value in the horizontal scaling ratio and the vertical scaling ratio as an actual scaling ratio, namely selecting 0.556 as the actual scaling ratio; finally, the horizontal resolution and the vertical resolution in the actual scaling ratio and the video resolution are adopted, the horizontal resolution of the canvas is determined to be 800/0.556-1439, and the vertical resolution of the canvas is determined to be 600/0.556-1080. That is, the canvas resolution of the display canvas used to output the video to be played is 1439 × 1080.
S103: and loading the video to be played to the full display canvas, and outputting the display canvas on the touch display screen according to the canvas resolution.
In some embodiments of the present disclosure, the loading of the to-be-played video value and the display canvas are performed by determining how to scale each video frame of the to-be-played video according to the horizontal resolution and the vertical resolution of the display canvas and the horizontal resolution and the vertical resolution of the to-be-played video, so as to fully cover the display canvas.
In some embodiments of the present disclosure, it may be determined how to zoom in and out with respect to the horizontal and vertical directions of the video to be played according to the actual zoom ratio determined in step S102, so that the video to be played is spread over the display canvas. Specifically, if the actual zoom ratio is greater than 1, the display canvas is fully paved with the video frames of the video to be played in an enlarging manner, and if the actual zoom ratio is less than 1, the display canvas is fully paved with the video to be played in a reducing manner.
After the display canvas is fully paved with the video to be played, the display canvas can be output on the touch display screen according to the canvas resolution. Because the display canvas refreshes the display canvas in real time according to the video frame frequency of the video to be played or the set refresh rate, the video playing can be realized by outputting the display canvas through the touch display screen.
By adopting the video playing method provided by the embodiment of the disclosure, when the to-be-played video is played in a full screen mode on the touch display screen, the canvas resolution is determined according to the video resolution and the screen resolution, so that the maximum resolution of the to-be-played video is not directly set as the screen resolution of the touch display screen as in the prior art, and therefore when the display canvas is output to the touch display screen to play the video, part of the display area of the touch display screen is not used for displaying the canvas.
After the touch instruction is generated by mistakenly touching the area outside the display canvas in the display screen, the touch instruction is not sent to the application program generating the display canvas, so that the application program is not triggered to display the output progress bar and the status bar, or the video playing is not triggered to stop.
Compared with the existing mode that the display canvas with the same resolution as the touch display screen is used for playing the video, the video playing method provided by the embodiment of the disclosure reduces the influence on the playing of the video caused by the fact that a user mistakenly touches a non-video playing area of the display screen, and improves the user experience.
In some embodiments of the present disclosure, the video playing method may further include step S100 before step S101 is executed, in addition to the aforementioned steps S101-S103.
Step S100: the placement state of the electronic device is determined.
In practical application, the electronic equipment may be in different placement states, and the placement state of the electronic equipment may be a horizontal screen state or a vertical screen state according to the long edge placement state identifier of the touch display screen; if the long edge of the touch display screen is vertically arranged, the arrangement state of the electronic equipment is a vertical screen state; if the long edge of the touch display screen is placed transversely, the electronic equipment is placed in a transverse screen state.
In some embodiments of the present disclosure, in a case that the video playing method includes step S100 of detecting a placement state of the electronic device, the method of determining the screen resolution of the touch display screen of the electronic device in step S101 may specifically include: and determining the screen resolution of the touch display screen according to the placement state.
To enhance the user experience, some electronic devices enable an auto-rotation function. When the touch display screen is switched from one placement state to another placement state, the playing content in the image canvas of the touch display screen is adaptively rotated. Since the horizontal resolution and the vertical resolution in the screen resolution of the electronic device may not be the same, in order to ensure that the maximum resolution for outputting the video to be played in a non-deformed manner is formed, the screen resolution of the touch display screen needs to be determined according to the placement state of the electronic device.
For example, the resolution of a touch display screen in a certain electronic device is 1920 in the length direction and 1080 in the width direction. If the electronic device is in the portrait state, the screen resolution of the electronic device is set to 1080 in the landscape resolution and 1920 in the portrait resolution. If the electronic device is in a landscape state, the screen resolution of the electronic device is set to 1920 in the landscape direction and 1080 in the portrait direction.
In some embodiments of the present disclosure, a method of determining a placement state of an electronic device may include the following steps. Firstly, acquiring a detection signal generated by an inertial sensor in electronic equipment; the placement state of the electronic device is then determined based on the detection signal generated by the inertial sensor.
In some embodiments of the present disclosure, an inertial sensor in the electronic device generates the detection signal in real time while the electronic device is in use. According to the detection signal, whether the placement state of the electronic equipment is a landscape screen state or a portrait screen state can be determined.
Fig. 2 is a flowchart of a method for outputting a display canvas using a touch display screen according to some embodiments of the present disclosure. As shown in fig. 2, in some embodiments of the present disclosure, a method of outputting a display canvas using a touch display screen includes steps S1031 to S1033.
S1031: a grip state of the electronic device is determined.
The holding state of the electronic device is a state in which the user holds the electronic device while using the electronic device. The grip state of the electronic device may include: left-hand grip, right-hand grip, upper-hand grip, lower-hand grip, bilateral grip, and quadrilateral grip.
A left grip is a left edge indicating that the user is holding the electronic device. A right grip refers to a user holding the right edge of the electronic device. The upper grip refers to a user holding an upper edge of the electronic device. Lower grip refers to a user gripping the lower edge of the electronic device. The left and right sides holding means that the user holds the left and right edges of the electronic device. The upper and lower double-sided holding is that a user holds the upper and lower edges of the electronic device. A four-sided grip refers to a user holding the four-sided edges of an electronic device.
When the electronic equipment is in different holding states, the situation that the fingers of the user touch the touch display screen of the electronic equipment by mistake is different.
For example, in the left-side holding state, the possibility that the user's hand touches the left area of the touch display screen by mistake is high, and the possibility that the user touches the other areas of the touch display screen by mistake is low. On the contrary, in the right holding state, the possibility that the right hand of the user mistakenly touches the right area of the touch display screen is high, and the possibility that the user mistakenly touches other areas of the touch display screen is low.
In some embodiments of the present disclosure, the step of acquiring the holding state of the electronic device may include steps S10311-S10312.
Step S10311: a detection signal generated by a sensor in an electronic device is acquired.
The sensor used in step S10311 may include at least one of a pressure sensor, a distance sensor, and a touch display screen; when a user holds the electronic device, the holding hand of the user triggers the sensor at the corresponding holding position to generate a detection signal.
Step S10312: and determining the holding state of the electronic equipment according to the detection signal.
In step S10312, the holding state of the electronic device may be determined based on the detection signal and the preset correspondence between the detection signal and the holding state.
For example, in the case that the user holds the electronic device on the left, if the hand of the user contacts the left edge of the touch display screen, the left area of the touch display screen is triggered to generate a detection signal. Correspondingly, according to the detection signal generated by the touch display screen, it can be determined that the user holds the electronic device on the left side.
For another example, if each frame of the electronic device is installed with a pressure sensor, the pressure sensor at the corresponding position may be triggered to generate a pressure signal when the user holds the electronic device. Correspondingly, according to the pressure signal and the position of the pressure sensor corresponding to the pressure signal, the holding state of the electronic device can be determined.
For another example, if a distance sensor is installed at an edge position of the electronic device, when the user holds the electronic device, the distance signal generated by the distance sensor at a position corresponding to the holding hand is a signal indicating that the distance is short. According to the distance signals generated by the distance sensors, which hand of the user is closer to the electronic equipment can be determined, and accordingly the holding state of the electronic equipment is determined.
In some embodiments of the present disclosure, the electronic device is an electronic device such as a smart phone and the like, in which four sides of the electronic device can be held, and in this case, the electronic device may further be configured with an inertial sensor, so as to determine a placement state of the electronic device according to a detection signal generated by the inertial sensor, and then perform comprehensive judgment according to the placement state and the detection signal generated by the pressure sensor, the distance sensor, and the touch display screen, so as to determine a holding state of the electronic device.
After determining the grip state of the electronic device, step S1032 may be performed.
Step S1032: a display position of the display canvas is determined according to the holding state.
In some embodiments of the present disclosure, the display position of the display canvas is determined according to the holding state, so that the display canvas is kept away from the hand of the user as far as possible, and then the user is prevented from shielding the display canvas by the hand and touching the display canvas by mistake.
FIG. 3 is a schematic view of a user holding an electronic device in some embodiments of the present disclosure. As shown in fig. 3, the holding state of the electronic device 31 is a right holding state, specifically, the user holds the right area of the electronic device with the right hand 32. At this time, the right hand of the user may block the right side area of the touch display screen 311 and may touch the right side area by mistake. To avoid the aforementioned occlusion and false touch problems, the display canvas 312 is disposed in the left area of the touch display screen. As shown in FIG. 3, the dashed box represents the display location of the display canvas 312.
Step S1033: the display canvas is output at the display location according to the canvas resolution.
After determining the display area of the touch display screen for displaying the canvas, step S1033 outputs the display canvas in the canvas area according to the canvas resolution, so as to implement playing of the video.
By adopting the video playing method provided by the embodiment of the disclosure, the display position of the display canvas in the touch display screen is determined by determining the holding state of the electronic equipment, so that the display canvas is far away from the hand of the user as far as possible, the situation that the hand shields the played video is avoided, and the situation that the hand touches the area where the display canvas is located by mistake is avoided.
Fig. 4 is a flowchart of another method for outputting a display canvas using a touch display screen according to some embodiments of the present disclosure. As shown in FIG. 4, in some further embodiments of the present disclosure, a method of outputting a display canvas includes steps S1034-S1036.
Step S1034: and outputting the display canvas according to the canvas resolution at the preset position of the touch display screen.
The preset position is preset for outputting a display position of the display canvas. For example, the preset position may be a middle position of the touch display screen, and the corresponding display canvas displays output in the middle of the touch display screen.
Step S1035: a movement operation instruction generated by touching the display canvas is detected.
The moving operation instruction is an instruction for triggering the moving of the display canvas position, and the moving operation instruction may be a sliding instruction or a dragging instruction. In some embodiments of the present disclosure, the moving operation instruction is an instruction generated by a user touching the display canvas, and the moving operation instruction is generated only when the touch operation acts on an area of the display canvas output by the touch display screen.
Step S1036: and adjusting the display position of the display canvas according to the moving operation instruction.
And adjusting the display position of the display canvas according to the operation instruction, namely moving the display position of the display canvas on the touch display screen according to the moving direction and/or the moving distance specified by the moving operation instruction.
Figure 5 is a schematic diagram of display canvas before and after adjustment according to some embodiments of the present disclosure. As shown in fig. 5, according to the detected moving touch instruction, the display canvas 51 moves from the middle position of the touch display screen 53 to the right side of the touch display screen 53 at the display position of the electronic device 52,
through the foregoing steps S1034-S1036, the electronic device may adjust the display position of the display canvas according to the user requirement, so as to adapt to the user requirement, and improve the user experience of the user.
