Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all 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.

The embodiment of the invention provides a video data processing method, electronic equipment and a computer readable storage medium. The video data processing method can be applied to an electronic device side and executed by the electronic device, and the electronic device provided by the embodiment of the invention comprises but is not limited to intelligent terminals such as mobile phones, tablet computers, computers and wearable devices.

Fig. 1 is a flowchart illustrating a video data processing method according to an embodiment of the present invention. As described with reference to fig. 1, the video data processing method includes step S110, step S120, and step S130. The video data processing method in the exemplary embodiment of fig. 1 is explained in detail below.

Referring to fig. 1, in step S110, an effective video area is determined in a video picture based on the content of the video picture displayed by the electronic device.

In an example embodiment, some videos have non-content borders, i.e., display borders that are unrelated to the video content. The non-content border may be a meaningless border filled around the video content, such as a solid black area at the periphery of the video, or a static border to which the video content has been previously added.

In an example embodiment, in a video picture, the active video area may be an area where meaningful video content is displayed, so the active video area does not include a non-content border. And when the electronic equipment identifies the non-content frame, determining an effective video area in the video picture according to the area of the non-content frame. In general, in an electronic device, after a region other than a content frame is subtracted from a complete display screen, the remaining region is an effective video region. For example, a recorded video of a news program is played on an electronic device, in a display screen of the electronic device, meaningful video content in the news program video is located in the center of the display screen, a part of pure black area without actual meaning exists on the upper side, the lower side, the left side and the right side of the meaningful video content, an area where the meaningful video content is located is an effective video area in a video picture, and the pure black area is a non-content frame in the video picture.

In an example embodiment, a user opens a certain video for watching, the video is in a full-screen display state, if a non-content frame exists in the video, the user wants to reduce the non-content frame as much as possible and magnify meaningful video content as much as possible, and then the user can notify the electronic device to automatically identify the non-content frame in a display screen on the electronic device through a preset mode. The preset mode may be a preset border recognition control on the electronic device, and after the user selects the control through operations including but not limited to single click, double click, long press, and sliding, the electronic device starts to automatically recognize the non-content border in the display screen.

In an example embodiment, determining an active video area in a video picture based on content of the video picture displayed by an electronic device includes: determining a region with a color value meeting the requirement of a preset color value in a video picture based on the content of the video picture; and taking the area with the color value meeting the preset color value requirement as an effective video area.

In an example embodiment, the electronic device automatically identifies an invalid video pixel region, i.e., a region in the video picture that is not a content border, and an active video pixel region based on color values in the video picture.

In example embodiments, there are two ways for the electronic device to obtain color values for a video picture. In one mode, in the process of decoding a video source by a video decoder, color values of video pictures corresponding to the video source are acquired from decoded data. The second method is that after the video decoder decodes the video source, the display screen of the electronic device displays the video picture of the video source, and the electronic device detects the video picture displayed on the display screen at regular time to obtain the color value of the video picture. And when the content of the target video area is magnified and displayed, the video decoding speed is not influenced, but the content of the magnified and displayed target video area is slower than the content of the magnified and displayed target video area by several seconds, and a user can see the process that the target video area is obviously enlarged. The second approach is to detect the color value of the video picture only when the video picture is displayed on the display screen after decoding for a period of time.

It is noted that in the exemplary embodiment, the video decoder decodes the video source, resulting in decoded data for video pictures that are some time later in the future, e.g., 30 seconds later, and the video picture currently being played is decoded in advance.

In the exemplary embodiment, the color values include, but are not limited to, RGB values, RGBA values, and YUV values, and the form of the color values is not particularly limited by the present invention.

In an exemplary embodiment, based on the content of the video frame, an area having a color value meeting a preset color value requirement is determined in the video frame, and the description may refer to table 1. The color values of the video pictures of a certain key frame of a certain video are shown in table 1, and it should be noted that the specific values in table 1 are only an example. The predetermined color value requirement may be that, based on any one of the values at the four corners in table 1, the values differing by 10 or less are regarded as the same color value, i.e., the difference between a certain value and the base value is regarded as the same color value from-10 to 10. For example, if the value 1 at the top left corner is selected as the base color value, then if the values-10, -5, 0, 2, 5, 10 appear, these values and 1 are all considered to be the same color value. And, if in a row of values, if the difference between each value and the base color value is not more than 3, the row of values is considered to be the same color value as the base value.

1	1	2	3	85	1	2	3	4
									2	3	2	3	1	4	5	8	1
1	82	82	52	82	82	52	62	2
									1	95	34	57	14	57	57	78	1
2	42	98	74	82	52	82	52	3
									1	45	6	57	6	6	26	47	2
3	45	57	6	35	73	82	6	1
									2	4	4	5	3	1	78	6	2

TABLE 1

It should be noted that, in the example embodiment, in the aforementioned preset color value requirement, the "difference between numerical values is less than or equal to 10 and is regarded as the same color value" is only an example, and the difference between numerical values may also be less than or equal to 5, or the difference between numerical values is greater than 20, and a specific numerical user may set the difference by himself as needed; "if the difference between each numerical value and the basic color value is not more than 3", this is only an example, and may also be not more than 10, or not more than 20, and the specific numerical value user may set itself as required.

In an example embodiment, the preset base color value may also be a value in the outermost row or the outermost column of table 1, such as a value 2 in the 5 th row of the 1 st column or a value 3 in the 5 th column of the 8 th row of table 1. The base color value should be the color of the pixel in the outermost circle in the video picture, because in general, the non-content borders are outside the active video area.

In an example embodiment, it may be determined that, in table 1, the numerical values of the row 1, the row 2, the row 8, the column 1 and the column 9 are all the same color value of the base color value "1", according to the aforementioned preset color value requirement. The 1 st, 2 nd and 8 th rows are rows of the same color value, and the 1 st and 9 th columns are columns of the same color value.

In an exemplary implementation, assume that the original width and height of the video frame corresponding to the values in table 1 is 170 × 180, the width is 170, and the height is 180, where the value unit has no effect. In table 1, a row of values and a column of values occupy 10 pixels, and the size of the effective video area in the video is calculated as follows:

width of effective video: 170- (1+1) × 10 ═ 150;

height of effective video: 180- (2+1) × 10 ═ 150.

In an example embodiment, the active video area may also be an area selected according to a point of interest of a user, for example, a news program is played on a full screen by a player, news scrolling below a video screen of the player is very interested by the user, and an area where the news scrolling is located is selected as the active video area through an area selection box provided by a player interface.

In an example embodiment, determining an active video area in a video picture based on content of the video picture displayed by an electronic device includes: receiving a region selection input performed in the video picture by a user based on the content of the video picture; in response to a region selection input, an active video region is determined in the video picture.

In an example embodiment, a user opens a certain video for watching, the video source is in a full-screen display state, if the user has an interest in the content of a certain area in the video source and wants to watch the video content of the area in a focused manner, the playing of the video source is paused, and area selection input is performed in a video picture.

In an example embodiment, the user performs the region selection input by presetting a region selection box similar to a drawing tool in the video picture, and the user moves the position of the region selection box and adjusts the size of the region selection box through a preset operation so as to select an effective video region in the video picture, namely a region of interest of the user, through the region selection box. The preset operation includes, but is not limited to, a single click, a double click, a long press, or a drag. The area selection frame may be rectangular, circular, or other shapes, which is not limited in the present invention.

In an example embodiment, the user performs the region selection input by sliding a finger of the user in a video screen on the electronic device, and the electronic device determines that the user wants to select the effective video region, namely the user region of interest, according to a track of the sliding of the finger.

In an example embodiment, the user performs the region selection input may also be that a plurality of regions are preset in the video screen, for example, the entire video screen is divided into 9 regions of squared, upper left, middle left, lower left, upper middle, middle, lower middle, upper right, middle right, and lower right. And (4) the user performs preset operation to select a lower left area, and the lower left area is determined as an effective video area, namely the area of interest of the user. The preset operation may be a single click or a long press, which is not particularly limited in the present invention.

In an exemplary embodiment, a user watches a recorded video of a news program, the video is displayed in a certain player on an electronic device in a full screen mode, the user suddenly notices that the message about earthquake is broadcasted in a rolling mode at the bottom of the news program, the specific details of the message, such as time, place and death number, are very concerned, and the area broadcasted in the rolling mode at the bottom of the video screen is only a narrow line of characters. The user pauses the playing of the video, clicks a preset effective video area selection control in the player interface, then the player enters a preset effective video area selection mode, a rectangular area selector appears in a video picture in the effective video area selection mode, the user can drag the area selector in the video picture to change the position of the area selector, or adjust the length and the width of the area selector to change the size of the area selector, and then the user can select an area containing messages about earthquakes at the lowest part of news programs in the video picture through the area selector, and the area is determined as an effective video area in the video picture.

In another exemplary embodiment, a user suddenly generates an interest in video content of a certain area during video playing, and clicks a preset effective video area selection control, so that after the player enters a preset effective video area selection mode, an area selector appears in a video picture, and the electronic device suspends video playing by default in the effective video area selection mode without the need of suspending the video in advance by the user.

In step S120, a target video area to be displayed enlarged is determined based on the effective video area.

In an example embodiment, the effective video area determined in step S110 may be an area selected by a user or an area automatically recognized by the electronic device. The electronic device may determine the effective video area as a target video area to be displayed enlarged. For example, the electronic device automatically recognizes that an effective video area is obtained, which is directly used as a target video area for enlarged display.

In an example embodiment, the electronic device may also adjust the effective video area first, and then determine the adjusted effective video area as a target video area to be displayed in an enlarged manner.

In an example embodiment, when the valid video area is an area selected by a user, the valid video area may be a regular rectangular area selected by a preset rectangular area selector, an irregular-shaped area determined according to a trace of a user's finger sliding, or an irregular-shaped area selected by a user among a plurality of preset irregular-shaped areas. At this time, the irregular area may be modified into a rectangular area according to a preset rule, and the rectangular area is determined as a target area to be enlarged and displayed. For example, the effective video area determined by the electronic device according to the trace of the sliding of the finger of the user is an elliptical area with uneven edge, at this time, the effective video area is adjusted according to the maximum length value and the maximum width value of the effective video area, the effective video area is automatically corrected to be a rectangular area just containing the effective video area, and the rectangular area obtained after correction is determined as the target video area to be displayed in an enlarged mode.

In an example embodiment, when the valid video area is an area automatically identified by the electronic device, there may be a rectangular area in which the valid video area obtained after the automatic identification by the electronic device is not a specification. At this time, the effective video area can be modified into a standard rectangular area according to a preset rule, and the rectangular area is determined as a target area to be magnified and displayed.

In an example embodiment, the electronic device plays a video in a first display area, which is a screen area for displaying a video picture. For example, when a video is displayed full-screen on the electronic device, the first display area is equivalent to a display screen of the electronic device; when the upper half of the display screen of the electronic equipment plays a video and the lower half of the display screen is a comment area of the video, the first display area is the upper half of the display screen. The electronic device records the width of the first display area and the height of the first display area.

In an example embodiment, when the video is displayed full screen, the electronic device records the width of the target video area to be displayed enlarged, the height of the target video area, the width screenwidth of the display screen on the electronic device, the height screenheight of the display screen, and the position coordinates (x, y) of the upper left corner of the target video area. The width screenwidth of a display screen on the electronic equipment is equal to the width of the first display area; the high screen height of the display screen is equal to the height of the first display area. In addition, the specific position of the target video area in the display screen on the electronic device can be determined from the position coordinates (x, y) of the upper left corner of the target video area and the width and height of the target video area.

In step S130, the content of the display target video area is enlarged.

In an example embodiment, the enlarging display of the content of the target video area includes: acquiring the aspect ratio of a first display area; the first display area is a screen area used for displaying a video picture; determining a magnification parameter of the target video area according to the aspect ratio of the first display area and the aspect ratio of the target video area; amplifying and displaying the content of the target video area in the first display area according to the amplification parameter; the height of the target video area after the enlarged display is equal to the height of the first display area, and the width of the target video area after the enlarged display is less than or equal to the width of the first display area; or the width of the target video area after the enlarged display is equal to the width of the first display area, and the height of the target video area after the enlarged display is less than or equal to the height of the first display area.

In an example embodiment, the first display region may be a display screen or a partial region in the display screen. When the first display area is a display screen, a video picture of an original video is in a full-screen display state, and when the first display area is a part of the display screen, the state of non-full-screen display is possible, for example, a video is played in the upper half part of the electronic device, and the lower half part of the electronic device is a comment area of the video.

In an exemplary embodiment, a method for determining a zoom-in parameter of a target video area is described in the present invention by taking an original video as an example of a full-screen display state.

In the exemplary embodiment, the coordinate position of the target video area in the display screen on the electronic device can be determined from the position coordinates (x, y) of the upper left corner of the target video area obtained in step S110 and the width and height of the target video area. Assuming that the lower left corner of the display screen is the origin of coordinates, the coordinate position of the center point of the target video region in the display screen is (x + width/2, y-height/2). The coordinate position of the center point of the display screen is determined to be (screen width/2, screen height/2) according to the wide screen width of the display screen and the high screen height of the display screen obtained in step S110. And moving the target video area to the central point of the display screen according to the coordinate position of the central point of the target video area in the display screen and the coordinate position of the central point of the display screen, namely moving the target video area until the central point of the target video area is superposed with the central point of the display screen.

In the exemplary embodiment, the aspect ratio screen/screen of the display screen may be obtained from the wide screen width of the display screen and the high screen height of the display screen obtained in step S110. The aspect ratio width/height of the target video area is determined based on the width of the target video area to be enlarged and displayed and the height of the target video area obtained in step S110. Determining a magnification parameter of the target video area according to the aspect ratio of the display screen and the aspect ratio of the target video area, wherein the specific rule is as follows:

1. if the aspect ratio of the display screen is greater than 1 and the aspect ratio of the target video region is greater than the aspect ratio of the display screen, the width newwidth of the target video region after enlarged display is equal to the width of the display screen, namely newwidth ═ screen width, the height newheight of the target video region after enlarged display is equal to the height of the target video region multiplied by the width of the display screen and divided by the width of the target video region, namely newheight ═ screen width/width;

2. if the aspect ratio of the display screen is more than 1, the aspect ratio of the target video area is less than the aspect ratio of the display screen, and the aspect ratio of the target video area is more than 1, the width of the target video area after enlarged display is equal to the width of the display screen, namely newwidth is equal to screenwidth, the height of the target video area after enlarged display is equal to the height of the target video area multiplied by the width of the display screen and divided by the width of the target video area, namely newheight is equal to height ═ screenwidth/width;

3. if the aspect ratio of the display screen is greater than 1, the aspect ratio of the target video area is smaller than the aspect ratio of the display screen, and the aspect ratio of the target video area is smaller than 1, the height of the target video area after enlarged display is equal to the height of the display screen, namely newheight is equal to screenheight, the width of the target video area after enlarged display is equal to the width of the target video area multiplied by the height of the display screen and divided by the height of the target video area, namely newwidth is equal to width of screenheight/height;

4. if the aspect ratio of the display screen is less than 1, the aspect ratio of the target video area is greater than the aspect ratio of the display screen, and the aspect ratio of the target video area is greater than 1, the width of the target video area after enlarged display is equal to the width of the display screen, namely newwidth is equal to screenwidth, and the height of the target video area after enlarged display is equal to the height of the target video area multiplied by the width of the display screen and divided by the width of the target video area, namely newheight is equal to height ═ screenwidth/width;

5. if the aspect ratio of the display screen is less than 1, the aspect ratio of the target video area is greater than the aspect ratio of the display screen, and the aspect ratio of the target video area is less than 1, the height of the target video area after enlarged display is equal to the height of the display screen, namely newheight is equal to screenheight, the width of the target video area after enlarged display is equal to the width of the target video area multiplied by the height of the display screen and divided by the height of the target video area, namely newwidth is equal to width of screenheight/height;

6. if the aspect ratio of the display screen is less than 1 and the aspect ratio of the target video region is less than the aspect ratio of the display screen, the height of the target video region after enlarged display is equal to the height of the display screen, namely newheight ═ screenheight, and the width of the target video region after enlarged display is equal to the width of the target video region multiplied by the height of the display screen and divided by the height of the target video region, namely newwidth ═ screenheight/height.

In an exemplary embodiment, as can be seen from the above rule, when the height of the target video region after the enlarged display of the target video region is the same as the height of the display screen, the width of the target video region after the enlarged display is necessarily smaller than or equal to the height of the display screen; when the width of the target video region after the enlarged display of the target video region is the same as the width of the display screen, the height of the target video region after the enlarged display is necessarily smaller than or equal to the height of the display screen. Therefore, the target video area can be enlarged to the maximum extent, and the target video area can be ensured not to exceed the range of the display screen after being enlarged so that the whole content of the target video area can not be seen.

In an exemplary embodiment, the position coordinates of the upper left corner of the enlarged target video region may be determined according to the enlargement parameter of the target video region obtained by the foregoing rule. If the position coordinates of the upper left corner of the target video region moved to the center of the display screen are (x, y) with the screen center as the origin of coordinates, the position coordinates of the upper left corner of the target video region after the target video region is enlarged and displayed are ((newwidth x)/width, (newheight y)/height).

In another example embodiment, the video content is identified in the electronic device as a target video area, and other areas in the display screen are non-content borders. The electronic device captures a target video area having a size of 140 x 130, a width of 140 and a height of 130. Assuming that the resolution of the display screen of the electronic device under the landscape screen is 1920 × 1080, the aspect ratio of the display screen is 16/9. The electronic device also obtains a protocol video aspect ratio of 17:18 and an aspect ratio of the target video area of 14/13. Therefore, the aspect ratio of the display screen is greater than that of the target video area, which can be understood that the height of the target video area is too large, and the height of the target video area needs to be adapted as a reference, otherwise, the display screen cannot be placed in the target video area, and video stretching occurs. As a result, the height of the target video region after the enlarged display is 1080 and the width of the target video region after the enlarged display is 1080/13 × 14 — 1163. At the moment, the target video area is enlarged as much as possible, and although partial invalid pixel points still exist in the display screen, the partial invalid pixel points can avoid image stretching deformation. The video content in the video is amplified in an equal ratio, the display resolution of the protocol video is reduced, partial invalid pixel points are removed, and the pixel points displayed by the effective video content are not reduced, so that the display area of the video content is enlarged, and the watching experience of a user is improved.

In an example embodiment, the contents of other areas in the video picture are displayed in an enlarged manner in the first display area according to the enlargement parameter; and the other areas are areas except the target video area in the video picture. Specifically, when the content of the target video area is enlarged in the first display area according to the enlargement parameter, the original whole video picture is enlarged, and the actual effect is that after the content of the target video area is enlarged and displayed according to the enlargement parameter, the video content which is enlarged and displayed according to the enlargement parameter and is connected with the target video area still exists in the non-target video area in the first display area, instead of the black screen.

In another exemplary embodiment, the electronic device modifies the encoded data by the video decoder to achieve the purpose of displaying the content of the target video area in an enlarged manner, and the encoded data of the non-target video area is identified and discarded, so that the actual effect on the display screen is that only the content of the target video area displayed in an enlarged manner exists in the first display area, and the other areas are pure black areas, i.e. no content areas.

According to the video data processing method in the exemplary embodiment of fig. 1, first, a target video area to be displayed in an enlarged manner is determined in a video picture according to the content of the video picture displayed on an electronic device; then, the content of the display target video area is enlarged. By the embodiment of the invention, the target video area with the display size needing to be adjusted can be determined in the video, the content of the target video area can be displayed in an enlarged mode, the effect of highlighting the content of the target video area is achieved, a user can watch the content of the target video area conveniently, and the user experience is improved.

In an example embodiment, if the user is no longer interested in the target video area in the video frame or interested in removing the non-content border, the electronic device is notified to return to the original normal video playing mode.

Fig. 2 is a schematic diagram of an application scenario for enlarging a region of interest of a user according to an embodiment of the present invention.

Referring to fig. 2, a video content 210 is displayed in a display screen on an electronic device, the video content 210 being in a full-screen display state.

In step S880, the data is transmitted to the video display output device.

In an example embodiment, the modified decoded data is transmitted to a video display output device, such as a display screen of an electronic device. Since the decoded data is modified and the video size is synchronized to the video display output device, the interface display layer does not need to be processed any more at this time, and the content of the target video area can be displayed on the video display output device in an enlarged manner. The non-target video area on the video display output device is displayed as a solid black area because the encoded data is discarded.

In step S1030, a video non-content area is detected.

In an example embodiment, the non-content border is identified according to the decoded data, and the detection mode may be manual identification or automatic identification. The manual identification can be that the user selects the video content without the non-content frame in the video picture, and can also be other manual operations. The automatic identification is that the electronic equipment obtains the color value of the video picture according to the decoded data, and then determines the video content and the non-content frame in the video picture according to the preset color value condition.

In step S1040, the true display scale is acquired.

In an example embodiment, after determining video content and a non-content frame in a video picture, the video content is taken as a target video area, the whole display screen is taken as a first display area, and according to an aspect ratio of the target video area and an aspect ratio of the first display area, a magnification parameter of the target video area is determined, that is, a true display proportion of the video content can be obtained.

In step S1050, the display screens are matched.

In an example embodiment, video content with a portion of non-content borders removed is displayed full screen in a display screen according to a true display scale of the video content. It should be noted that, in order to ensure that the video is not stretched and deformed, the non-content border may not be completely removed, but the video content is displayed in a full screen mode, which significantly improves the visual effect.
