技术领域technical field

本公开实施例涉及计算机技术领域，尤其涉及一种作品封面显示方法，作品封面显示装置，以及实现作品封面显示方法的计算机可读存储介质和电子设备。The embodiments of the present disclosure relate to the field of computer technology, and in particular, to a method for displaying a work cover, a device for displaying a work cover, and a computer-readable storage medium and electronic equipment for realizing the method for displaying a work cover.

背景技术Background technique

随着移动互联网的发展，视频作品如短视频越来越盛行。为了使用户尽可能对视频作品感兴趣，从而从中选择视频作品进行点击播放，通常可对视频作品设置相应的视频封面以吸引用户点击播放视频。With the development of the mobile Internet, video works such as short videos are becoming more and more popular. In order to make the user interested in the video works as much as possible, so as to select the video works and click to play, usually a corresponding video cover can be set for the video works to attract the users to click to play the video.

相关技术中，视频封面可采用动态封面图，其可以提供更为丰富的信息，从而增加了用户点击播放视频的概率。In related technologies, the video cover may adopt a dynamic cover image, which can provide richer information, thereby increasing the probability of the user clicking to play the video.

但是，视频封面采用动态封面图时存在一些显示异常问题，例如构成动态封面图的多帧图像相同，则视频封面显示效果是静态图像，但实际是动态图像，造成一定的数据流量的浪费；另外，构成动态封面图的相邻帧的图像如果差异过大，会造成跳闪现象，导致视频封面显示视觉效果较差，尤其当展示用户的视频作品集合时，显示页面的整体协调性较差，影响视觉观感，从而降低了用户点击播放视频的概率。However, when the video cover adopts a dynamic cover image, there are some abnormal display problems. For example, if multiple frames of images constituting the dynamic cover image are the same, the video cover display effect is a static image, but it is actually a dynamic image, resulting in a certain waste of data traffic; , if the images of the adjacent frames that make up the dynamic cover image differ too much, it will cause jumping and flashing, resulting in poor visual effect of the video cover display, especially when displaying the user's video works collection, the overall coordination of the displayed page is poor, It affects the visual perception, thereby reducing the probability of users clicking to play the video.

为了能够更清楚地理解本公开的上述目的、特征和优点，下面将对本公开的方案进行进一步描述。需要说明的是，在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合。In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其他不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不是全部的实施例。In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways than described here; obviously, the embodiments in the description are only some of the embodiments of the present disclosure, and Not all examples.

应当理解，在下文中，“至少一个(项)”是指一个或者多个，“多个”是指两个或两个以上。“和/或”用于描述关联对象的关联关系，表示可以存在三种关系，例如，“A和/或B”可以表示：只存在A，只存在B以及同时存在A和B三种情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，“a和b”，“a和c”，“b和c”，或“a和b和c”，其中a，b，c可以是单个，也可以是多个。It should be understood that hereinafter, "at least one (item)" means one or more, and "multiple" means two or more. "And/or" is used to describe the association relationship of associated objects, which means that there can be three kinds of relationships, for example, "A and/or B" can mean: only A exists, only B exists, and A and B exist at the same time. Among them, A and B can be singular or plural. The character "/" generally indicates that the contextual objects are an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one item (piece) of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c ", where a, b, c can be single or multiple.

图1为本公开示例实施例示出的作品封面显示方法流程图，该作品封面显示方法可以由服务器执行，也可以由客户端执行。本实施例中以由服务器执行为例进行说明，该方法具体可以包括以下步骤：Fig. 1 is a flowchart of a method for displaying a work cover according to an example embodiment of the present disclosure. The method for displaying a work cover may be executed by a server or a client. In this embodiment, the execution by the server is taken as an example for illustration, and the method may specifically include the following steps:

步骤S101：接收多媒体作品的获取请求。Step S101: Receive a request for acquiring a multimedia work.

示例性的，服务器可以是客户端如智能手机上安装的例如视频应用程序对应的视频服务器。多媒体作品例如可以是但不限于音频作品或者视频作品，本实施例中以视频作品如短视频作品为例说明。Exemplarily, the server may be a client such as a video server corresponding to a video application program installed on a smart phone. A multimedia work may be, for example but not limited to, an audio work or a video work. In this embodiment, a video work such as a short video work is used as an example for illustration.

用户可以通过智能手机拍摄制作短视频作品，自定义设置短视频作品的封面图如静态封面图或者动态封面图，之后该制作的短视频作品可以通过视频应用程序发布上传至视频服务器，其他用户可以在自己的智能手机上开启视频应用程序从而从视频服务器获取自己或他人上传的短视频作品进行观看。Users can shoot and make short video works with their smartphones, and customize the cover image of the short video works, such as static cover images or dynamic cover images. After that, the short video works can be published and uploaded to the video server through the video application, and other users can Start the video application on your smartphone to obtain short video works uploaded by yourself or others from the video server for viewing.

具体的，作为一个示例，用户在点击开启视频应用程序之后，在视频应用程序的显示界面中例如点击一个用户的昵称等触发生成短视频作品的获取请求，获取请求可以包含用户标识如昵称或ID等。该获取请求由视频应用程序发送至视频服务器，即视频服务器接收获取请求。Specifically, as an example, after the user clicks to open the video application, in the display interface of the video application, for example, clicks on a user's nickname to trigger a request to generate a short video work. The request may include user identification such as nickname or ID wait. The acquisition request is sent to the video server by the video application, that is, the video server receives the acquisition request.

步骤S102：响应所述获取请求获取多媒体作品，所述多媒体作品包括动态封面图。Step S102: Acquire a multimedia work in response to the acquisition request, and the multimedia work includes a dynamic cover image.

具体的，视频服务器响应短视频作品的获取请求，从视频服务器中获取对应的用户的一个或多个短视频作品，例如基于用户标识获取对应的用户的一个短视频作品或多个短视频作品即视频作品集合，每个短视频作品可以包括动态封面图，动态封面图是从短视频作品中抽取的多帧图像构成的。Specifically, the video server responds to the acquisition request of the short video works, and obtains one or more short video works of the corresponding user from the video server, for example, based on the user identifier, one short video work or multiple short video works of the corresponding user are acquired. A collection of video works, each short video work can include a dynamic cover image, and the dynamic cover image is composed of multiple frames of images extracted from the short video work.

步骤S103：检测所述动态封面图是否存在显示异常。Step S103: Detect whether the dynamic cover image is displayed abnormally.

具体的，视频服务器获取短视频作品之后，对于短视频作品的动态封面图进行检测，判断动态封面图是否存在显示异常，显示异常例如实际是动态图但显示效果是静态的，或者出现跳闪现象，即构成动态封面图的相邻帧的图像差异过大，显示视觉效果较差。Specifically, after the video server obtains the short video work, it detects the dynamic cover image of the short video work to determine whether there is any abnormality in the display of the dynamic cover image. For example, the abnormal display is actually a dynamic image but the display effect is static, or there is a phenomenon of flickering , that is, the difference between the images of the adjacent frames constituting the dynamic cover image is too large, and the visual effect of the display is poor.

步骤S104：若检测到所述动态封面图存在显示异常，则将所述动态封面图替换为静态封面图，并返回包括替换后的静态封面图的多媒体作品。Step S104: If it is detected that the dynamic cover image is displayed abnormally, replace the dynamic cover image with a static cover image, and return the multimedia work including the replaced static cover image.

具体的，视频服务器检测确定短视频作品的动态封面图存在显示异常时，将所述动态封面图替换为静态封面图，也即替换了短视频作品，返回替换后的短视频作品至视频应用程序中显示。其中，该静态封面图可以是用户之前为其制作的短视频作品自定义设置的静态封面图，但也不限于此。Specifically, when the video server detects that the dynamic cover image of the short video work is displayed abnormally, it replaces the dynamic cover image with a static cover image, that is, replaces the short video work, and returns the replaced short video work to the video application program displayed in . Wherein, the static cover image may be a static cover image custom-set by the user for a short video work previously made by the user, but it is not limited thereto.

本公开实施例提供的上述作品封面显示方法，可以实现对多媒体作品的动态封面图的显示异常检测，当动态封面图存在显示异常时，直接将动态封面图替换为静态封面图，之后返回替换后的短视频作品至视频应用程序中显示，如此在动态封面图显示异常时返回的短视频作品包括一帧静态封面图而不是多帧图像构成的动态封面图，可以减少数据流量的浪费；另外，客户端显示替换后的短视频作品，解决了动态封面图的跳闪现象，使得多媒体作品如视频的封面显示视觉效果较好，当客户端同时展示用户的视频作品集合时，显示页面的整体协调性较好，视觉观感好，在一定程度上可增加用户点击播放视频的概率。The above-mentioned work cover display method provided by the embodiment of the present disclosure can realize the display abnormality detection of the dynamic cover image of a multimedia work. When the dynamic cover image has an abnormal display, directly replace the dynamic cover image with a static cover image, and then return to the replaced one. The short video works can be displayed in the video application, so when the dynamic cover image displays abnormally, the short video works returned include a static cover image instead of a dynamic cover image composed of multiple frames of images, which can reduce the waste of data traffic; in addition, The client displays the replaced short video works, which solves the flickering phenomenon of the dynamic cover image, and makes the cover display of multimedia works such as videos have better visual effects. When the client displays the user's video works collection at the same time, the overall coordination of the display page is displayed. It has good performance and good visual perception, which can increase the probability of users clicking to play videos to a certain extent.

可选的，在本公开的一些实施例中，参考图2中所示，步骤S103中检测所述动态封面图是否存在显示异常的步骤，具体可以包括以下步骤：Optionally, in some embodiments of the present disclosure, referring to FIG. 2 , the step of detecting whether the dynamic cover image is displayed abnormally in step S103 may specifically include the following steps:

步骤S201：获取归属于所述动态封面图的连续N帧图像，N是大于1的自然数。Step S201: Obtain N consecutive frames of images belonging to the dynamic cover image, where N is a natural number greater than 1.

示例性的，例如N的取值是5，但不限于此。此时则可以获取构成动态封面图的连续5帧图像，如依序排列的图像1、图像2、图像3、图像4和图像5。Exemplarily, for example, the value of N is 5, but not limited thereto. At this time, five consecutive frames of images constituting the dynamic cover image can be acquired, such as image 1, image 2, image 3, image 4 and image 5 arranged in sequence.

步骤S202：确定所述连续N帧图像中任意相邻两帧图像的属性参数值，共得到(N-1)个相邻两帧图像的属性参数值，所述属性参数值与图像的像素相关。Step S202: Determine the attribute parameter values of any two adjacent frames of images in the continuous N frames of images, and obtain (N-1) attribute parameter values of two adjacent frames of images in total, and the attribute parameter values are related to the pixels of the images .

示例性的，确定连续5帧图像如图像1、图像2、图像3、图像4和图像5之后，确定相邻两帧图像的属性参数值，例如图像1和图像2的属性参数值1，图像2和图像3的属性参数值2，图像3和图像4的属性参数值3，以及图像4和图像5的属性参数值4，即共得到4个相邻两帧图像的属性参数值。Exemplarily, after determining five consecutive frames of images such as image 1, image 2, image 3, image 4, and image 5, determine the attribute parameter values of two adjacent frames of images, for example, the attribute parameter values of image 1 and image 2 are 1, and the image The attribute parameter value 2 of image 2 and image 3, the attribute parameter value 3 of image 3 and image 4, and the attribute parameter value 4 of image 4 and image 5, that is, a total of 4 attribute parameter values of two adjacent frames of images are obtained.

步骤S203：在每个所述相邻两帧图像的属性参数值均大于或等于属性参数阈值时，确定所述动态封面图存在显示异常。Step S203: When the attribute parameter values of each of the two adjacent frames of images are greater than or equal to the attribute parameter threshold, it is determined that the dynamic cover image has a display abnormality.

示例性的，在例如上述属性参数值1、属性参数值2、属性参数值3和属性参数值4均大于或等于属性参数阈值X时，确定动态封面图存在显示异常，然后返回执行步骤S104。Exemplarily, when the attribute parameter value 1, the attribute parameter value 2, the attribute parameter value 3 and the attribute parameter value 4 are all greater than or equal to the attribute parameter threshold value X, it is determined that the dynamic cover image is displayed abnormally, and then returns to step S104.

本公开实施例提供的上述作品封面显示方法，通过动态封面图中相邻两帧图像的属性参数值进行检测，可以较为准确地检测多媒体作品的动态封面图的显示异常，当检测到动态封面图存在显示异常时，直接将动态封面图替换为静态封面图，之后返回替换后的短视频作品至视频应用程序中显示，如此在动态封面图显示异常时返回的短视频作品包括一帧静态封面图而不是多帧图像构成的动态封面图，可以减少数据流量的浪费；另外，客户端显示替换后的短视频作品，解决了动态封面图的跳闪现象，使得多媒体作品如视频的封面显示视觉效果较好，当客户端同时展示用户的视频作品集合时，显示页面的整体协调性较好，视觉观感好，在一定程度上可增加用户点击播放视频的概率。The above method for displaying the cover of a work provided by the embodiment of the present disclosure detects the attribute parameter values of two adjacent frames of images in the dynamic cover image, and can more accurately detect the display abnormality of the dynamic cover image of a multimedia work. When the dynamic cover image is detected When there is an abnormal display, directly replace the dynamic cover image with a static cover image, and then return the replaced short video work to the video application for display, so that when the dynamic cover image displays abnormally, the returned short video work includes a frame of static cover image Instead of a dynamic cover image composed of multiple frames of images, it can reduce the waste of data traffic; in addition, the client displays the replaced short video works, which solves the flickering phenomenon of the dynamic cover image and makes the cover of multimedia works such as videos display visual effects Better, when the client side displays the user's video works collection at the same time, the overall coordination of the displayed page is better, the visual perception is good, and the probability of the user clicking to play the video can be increased to a certain extent.

可选的，在上述实施例的基础上，本公开的一些实施例中，如图3中所示，步骤S202 中确定所述连续N帧图像中任意相邻两帧图像的属性参数值的步骤，具体可以包括以下步骤：Optionally, on the basis of the above-mentioned embodiments, in some embodiments of the present disclosure, as shown in FIG. 3 , in step S202, the step of determining the attribute parameter values of any two adjacent frames of images in the continuous N frames of images , which may specifically include the following steps:

步骤S301：计算相邻两帧图像中每个对应像素点的像素差值。Step S301: Calculate the pixel difference value of each corresponding pixel in two adjacent frames of images.

可以理解的是，由于构成动态封面图的连续N帧图像均来自于短视频作品，因此每帧图像包含相同数量的像素点，例如图像1和图像2均包括10000个像素点，此处仅为举例说明，并不限于此。It is understandable that since the N consecutive frames of images constituting the dynamic cover image all come from short video works, each frame of images contains the same number of pixels, for example, image 1 and image 2 both contain 10,000 pixels, here only By way of example, not limitation.

在本实施例中，针对相邻两帧图像如图像1和图像2，计算图像1和图像2中每个对应像素点的像素差值，例如图像1中的像素点A对应图像2中的像素点A’，确定像素点A的像素值是P1，而像素点A’的像素值是P2，则像素差值P＝P1-P2。图像1和图像2中其他像素点也是同样的方法确定像素差值，直至确定例如10000个像素差值。其他相邻两帧图像如图像2和图像3，图像3和图像4，以及图像4和图像5也是同样的计算方式确定像素差值，此处不再详述。In this embodiment, for two adjacent frames of images such as image 1 and image 2, the pixel difference value of each corresponding pixel in image 1 and image 2 is calculated, for example, pixel A in image 1 corresponds to a pixel in image 2 For point A', it is determined that the pixel value of pixel point A is P1, and the pixel value of pixel point A' is P2, then the pixel difference value P=P1-P2. The same method is used to determine the pixel difference values of other pixels in image 1 and image 2 until, for example, 10,000 pixel difference values are determined. Other two adjacent frames of images, such as image 2 and image 3, image 3 and image 4, and image 4 and image 5, also determine the pixel difference in the same calculation method, which will not be described in detail here.

步骤S302：确定相邻两帧图像中目标像素点的数量，所述目标像素点是相邻两帧图像中像素差值大于预设像素阈值的像素点。Step S302: Determine the number of target pixel points in two adjacent frames of images, where the target pixel points are pixels with a pixel difference greater than a preset pixel threshold in the two adjacent frames of images.

示例性的，预设像素阈值可以根据需要设置，对此不作限制。具体的，作为示例，通过上述方式确定例如图像1和图像2中10000个像素差值，然后从中选择像素差值大于预设像素阈值的像素点即目标像素点，最后统计目标像素点的数量，例如有9000个目标像素点。Exemplarily, the preset pixel threshold can be set as required, without limitation. Specifically, as an example, determine the difference between, for example, 10,000 pixels in image 1 and image 2 by the above method, and then select the pixel whose pixel difference is greater than the preset pixel threshold, that is, the target pixel, and finally count the number of target pixels, For example, there are 9000 target pixels.

步骤S303：计算所述目标像素点的数量与相邻两帧图像中任一图像的像素点总数的比值，将所述比值作为所述属性参数值。Step S303: Calculate the ratio of the number of target pixels to the total number of pixels in any one of the two adjacent frames of images, and use the ratio as the attribute parameter value.

具体的，计算目标像素点的数量如9000与相邻两帧图像中任一图像的像素点总数如10000的比值，即9000/10000＝90％，该比值90％即为图像1和图像2的属性参数值1。其他相邻两帧图像的属性参数值的计算也是上述同样的过程。步骤S303之后即可跳转执行步骤S203，以判断动态封面图是否存在显示异常。Specifically, calculate the ratio of the number of target pixels, such as 9000, to the total number of pixels in any image in two adjacent frames of images, such as 10000, that is, 9000/10000=90%, and the ratio of 90% is the ratio of image 1 and image 2 The attribute parameter value is 1. The calculation of the attribute parameter values of other two adjacent frames of images is also the same process as above. After step S303, skip to step S203 to determine whether the dynamic cover image is displayed abnormally.

For example, two adjacent frames of image 1 and image 2 are preprocessed into RGB three-channel image 1 and RGB three-channel image 2 respectively.
