具体实施方式detailed description
下面结合附图对本申请实施例进行详细描述。The embodiments of the present application are described in detail below with reference to the drawings.
参见图1,为本申请实施例适用的一种系统架构示意图。如图1所示,该系统架构中包括服务器101、网络102以及客户端设备103,服务器101和客户端设备103可通过网络102进行交互。其中,客户端设备103可以包括多个,图中仅以一个作为示例。FIG. 1 is a schematic diagram of a system architecture applicable to an embodiment of the present application. As shown in FIG. 1, the system architecture includes a server 101, a network 102, and a client device 103. The server 101 and the client device 103 can interact through the network 102. The client device 103 may include multiple ones, and only one is taken as an example in the figure.
服务器101可提供视频服务,存储有视频的媒体资源。具体地,客户端设备103可以向服务器101请求视频媒体资源进行下载,该请求可以是向服务器101请求播放一种清晰度或多种清晰度的视频资源;服务器101中存储有至少一种清晰度的该视频文件,通常为多种清晰度的该视频文件,即一个视频文件有480P、720P、1080P、4K等清晰度的格式,服务器101可根据该请求将相应的视频片段发送给该客户端设备103,客户端设备103可对下载得到的视频片段进行缓存和播放。The server 101 may provide a video service and store media resources of the video. Specifically, the client device 103 may request the video media resource for downloading from the server 101, and the request may be a request from the server 101 to play a video resource of one definition or multiple definitions; the server 101 stores at least one definition The video file is usually a multi-definition video file, that is, a video file has a format of 480P, 720P, 1080P, 4K and other definitions. The server 101 can send the corresponding video clip to the client according to the request. The device 103 and the client device 103 may cache and play the downloaded video clip.
按照现有的下载策略,客户端设备103中预置多种分辨率的选择,并按照高分辨率优先的原则进行视频的媒体资源下载。比如,客户端设备103按照清晰度优先的播放顺序依次播放4K、1080P、720P、480P、360P等格式的 视频文件。在网络带宽允许的情况下,按照该顺序客户端会首先下载清晰度为4K的该视频的媒体资源,若无该清晰度的媒体资源,则按照上述顺序,下载清晰度为1080P的该视频的媒体资源,若再无该清晰度的媒体资源,则依序下载清晰度为720P的该视频的媒体资源,以此类推。According to the existing download strategy, the client device 103 presets the selection of multiple resolutions, and downloads the media resources of the video according to the principle of high resolution priority. For example, the client device 103 plays video files in the format of 4K, 1080P, 720P, 480P, 360P, etc. in order according to the playback priority order of clarity. If the network bandwidth allows, the client will first download the media resource of the video with 4K resolution in this order. If there is no media resource of the definition, then download the video with 1080P resolution in the above order. Media resources. If there are no more media resources of this definition, then the media resources of this video with a resolution of 720P are sequentially downloaded, and so on.
另外,在网络带宽发生变化时,按照现有技术,如图2所示,客户端会动态选择不同分辨率的视频片段,原则也是选择该带宽条件下最高分辨率的视频媒体资源,这样可保证视频播放不中断。示例性的,假如客户端(电视)支持的视频格式包括1080P@60(分辨率为1080P,屏幕帧率为60帧)、1080P@30、4K@30、720P@60等,在一种应用情形下用户观看田径比赛,如图5所示,按照现有技术的原有方案,在视频起播瞬间电视判断网络带宽为20Mbps,在该带宽条件下,服务器端可提供下载的最高分辨率的媒体资源的分辨率和帧率为1080@30,则按照现有技术的预选规则客户端会下载该视频的1080P@30帧格式的视频媒体资源进行播放;当网络带宽稳定且提升为40Mbps时,此时该带宽条件所允许下载的服务器视频媒体资源包括4K@30、1080P@60、1080P@30、720P@60,按照现有技术分辨率优先的下载策略客户端会切换4K@30格式的该视频的媒体资源进行下载并播放。In addition, when the network bandwidth changes, according to the existing technology, as shown in Figure 2, the client will dynamically select video clips with different resolutions. The principle is to select the highest resolution video media resource under this bandwidth condition, which can ensure Video playback is not interrupted. For example, if the video format supported by the client (TV) includes 1080P @ 60 (resolution is 1080P, screen frame rate is 60 frames), 1080P @ 30, 4K @ 30, 720P @ 60, etc., in an application scenario Users watch the track and field competition, as shown in Figure 5. According to the original scheme of the prior art, the TV judges that the network bandwidth is 20Mbps at the moment of video start. Under this bandwidth condition, the server can provide the highest resolution media for download. The resolution and frame rate of the resource are 1080 @ 30, according to the preselection rules of the prior art, the client will download the video media resource of 1080P @ 30 frame format for the video to play; when the network bandwidth is stable and promoted to 40Mbps, this The server video media resources allowed to be downloaded under this bandwidth condition include 4K @ 30, 1080P @ 60, 1080P @ 30, 720P @ 60. According to the resolution policy of the prior art, the client will switch the video in 4K @ 30 format. Download and play.
视频帧率,为用于测量显示帧数的度量。一般理解为1秒钟时间里传输的图片的帧数(Frames per second,简称FPS),也可以理解为图形处理器每秒钟能够刷新几次。由于人类眼睛的生理结构,若所看画面帧率高于16时,人眼会认为该画面是连贯的,此现象称之为视觉停留。高的帧率可以得到更流畅更逼真的动画,一般来说30pfs是可以接受的,但将性能提升至60fps则可明显提升交互感和逼真感。Video frame rate, a metric used to measure the number of displayed frames. Generally understood as the frames per second (FPS) of a picture transmitted in one second, it can also be understood as the graphics processor can refresh several times per second. Due to the physiological structure of the human eye, if the frame rate of the viewed picture is higher than 16, the human eye will think that the picture is coherent, and this phenomenon is called visual stay. High frame rate can get smoother and more realistic animation, generally 30pfs is acceptable, but increasing the performance to 60fps can significantly improve the sense of interaction and realism.
由上所述可知,对于一些特殊场景,用户对视频帧率的需求比分辨率的需求更高。采用现有分辨率优先的视频媒体资源下载播放的策略不能满足用户该方面的需求。因此,亟需一种更优的视频媒体资源获取的方法,使下载播放的视频更符合用户需求。It can be known from the above that, for some special scenarios, the user's demand for video frame rate is higher than the demand for resolution. The existing strategy of downloading and playing video media resources with priority resolution cannot meet users' needs in this respect. Therefore, there is an urgent need for a better method for acquiring video media resources to make the downloaded and played videos more suitable for user needs.
参见图3,为本申请实施例提供的一种媒体资源获取的方法流程图。如图 3所示,该方法包括:Referring to FIG. 3, a flowchart of a method for acquiring a media resource according to an embodiment of the present application is shown. As shown in Figure 3, the method includes:
S301:判断目标视频是否属于预设类型。S301: Determine whether the target video belongs to a preset type.
S302:若是,在网络带宽和终端设备硬件播放能力允许的情况下,从服务器提供的目标视频的媒体资源中获取最高帧率下的最高分辨率的媒体资源进行下载。S302: If the network bandwidth and the hardware playback capability of the terminal device allow, obtain the media resource of the highest resolution at the highest frame rate from the media resource of the target video provided by the server for downloading.
本申请实施例,当客户端判断目标视频属于预设类型时,会在网络带宽和终端设备播放能力允许的情况下从服务器提供的目标视频的媒体资源中获取最高帧率下的最高分辨率的媒体资源进行下载。该视频媒体资源的下载策略保证了包含快速运动画面的视频的播放流畅度,相比现有技术提升了视频交互感和逼真感,更符合该场景下的用户需求。In the embodiment of the present application, when the client judges that the target video belongs to a preset type, it will obtain the highest resolution at the highest frame rate from the media resources of the target video provided by the server when the network bandwidth and terminal device playback capabilities allow it. Media resources for download. The download strategy of the video media resource ensures the smoothness of playback of videos containing fast moving pictures. Compared with the existing technology, it improves the sense of video interaction and fidelity, which is more in line with the needs of users in this scenario.
其中,预设类型是指视频为包含快速运动画面的视频。在一种可能的实施方式中,通过从服务器端获取该视频的节目描述信息来判断目标视频是否属于预设类型,比如节目描述信息指示该视频为一场体育类的田径比赛,可判断该目标视频属于预设类型。Among them, the preset type refers to a video that includes a fast moving picture. In a possible implementation manner, the program description information of the video is obtained from the server to determine whether the target video belongs to a preset type. For example, the program description information indicates that the video is a sports track and field competition, and the target may be determined. The video is a preset type.
在另一种可能的实施方式中,终端通过对获取的部分目标视频的片段进行运动分析判断目标视频是否属于预设类型。本申请实施例对目标视频是否属于预设类型的判断并不局限于上述两种实施方式。In another possible implementation manner, the terminal determines whether the target video belongs to a preset type by performing motion analysis on the obtained segment of the target video. The determination of whether the target video belongs to a preset type in the embodiments of the present application is not limited to the above two implementation manners.
对于步骤S302,可选的,服务器端向客户端发送当前网络带宽情况可提供的所有视频媒体资源的信息,信息包括媒体资源的分辨率和帧率及对应的统一资源定位器(Uniform Resource Locator,简称URL)地址;客户端在步骤S301判断该视频属于预设类型的前提下,向服务器发送获取经判断策略确定的最高帧率下最高分辨率视频媒体资源的请求,请求中包含所请求的网络带宽和终端硬件播放能力允许条件下最高帧率下最高分辨率的媒体资源的URL地址;服务器端向客户端发送对应媒体资源;客户端对下载的最高帧率下的最高分辨率媒体资源进行播放。For step S302, optionally, the server sends to the client information about all video media resources that can be provided by the current network bandwidth situation. The information includes the resolution and frame rate of the media resources and the corresponding Uniform Resource Locator, URL); the client sends a request to the server to obtain the highest-resolution video media resource at the highest frame rate determined by the judgment policy, on the premise that the video is of a preset type in step S301, and the request includes the requested network The bandwidth and the terminal hardware playback capability allow the URL address of the highest resolution media resource at the highest frame rate; the server sends the corresponding media resource to the client; the client plays the highest resolution media resource at the highest frame rate downloaded .
在一种可能的实施方式中,当网络带宽由差变好,如视频媒体从起播至正常播放时,如图4所示,从服务器提供的目标视频的媒体资源中获取最高 帧率下的最高分辨率媒体资源进行下载,包括:In a possible implementation manner, when the network bandwidth changes from poor to good, such as when video media is played from normal to normal, as shown in FIG. 4, the media at the highest frame rate is obtained from the media resources of the target video provided by the server. Download the highest resolution media resources, including:
S401、确定分辨率与目标视频当前播放媒体资源分辨率相同且帧率满足小于等于屏幕刷新率的所有媒体资源的最高帧率为第一帧率。S401. Determine that the highest frame rate of all media resources whose resolution is the same as that of the currently played media resources of the target video and whose frame rate satisfies the screen refresh rate is the first frame rate.
对于客户端而言,当获取视频的帧率超过屏幕刷新率时,由于监视器不能以这么快的速度更新,这样导致超过刷新率的帧率就被浪费掉。因此对视频媒体资源帧率的选择要考虑屏幕刷新率。For the client, when the frame rate of the acquired video exceeds the screen refresh rate, because the monitor cannot update at such a fast rate, the frame rate exceeding the refresh rate is wasted. Therefore, the selection of the frame rate of video media resources must consider the screen refresh rate.
S402、进一步确定帧率为第一帧率的媒体资源中分辨率满足小于等于屏幕分辨率的最高分辨率为第一分辨率。S402. It is further determined that the highest resolution in the media resource with a frame rate of the first frame rate that is less than or equal to the screen resolution is the first resolution.
S403、从服务器提供的目标视频的媒体资源中获取帧率为第一帧率且分辨率为第一分辨率的媒体资源进行下载。S403. Obtain and download the media resources with the first frame rate and the first resolution from the media resources of the target video provided by the server.
下面结合图5和图6,相比现有技术对本申请实施例中图4的方法进行示例性说明。如图5所示,和前述现有技术的应用场景一致,客户端(电视)支持的视频格式包括1080P@60、1080P@30、4K@30、720P@60,用户观看田径比赛,按照图3所示方案,在视频起播瞬间电视判断网络带宽为20Mbps,在该带宽条件下,服务器端可提供下载的媒体资源的分辨率和帧率为1080@30的视频格式,客户端会下载该视频的1080P@30帧的视频媒体资源进行播放;当网络带宽稳定且提升为40Mbps时,此时该带宽条件所允许下载的服务器视频媒体资源包括4K@30、1080P@120、1080P@60、1080P@30、720P@60,此时客户端判断该视频的类型属于预设类型,则先确定当前播放的起播视频媒体片段分辨率为1080P,该分辨率下的媒体资源的帧率包括120帧、60帧和30帧,由于电视屏幕刷新率最大支持60帧、屏幕分辨率为1080P,因此确定该网络带宽下满足电视硬件播放能力的媒体资源为1080P@60,客户端会切换1080P@60格式的该视频的媒体资源进行下载并播放。The method of FIG. 4 in the embodiment of the present application is described below with reference to FIGS. 5 and 6 by way of example. As shown in FIG. 5, consistent with the foregoing application scenario of the prior art, the video formats supported by the client (television) include 1080P @ 60, 1080P @ 30, 4K @ 30, 720P @ 60, and users watch the track and field competitions according to FIG. 3 In the scheme shown, the TV judges that the network bandwidth is 20Mbps at the moment of video start. Under this bandwidth condition, the server can provide the resolution of the downloaded media resources and the frame rate 1080 @ 30 video format, and the client will download the video. 1080P @ 30 frames of video media resources for playback; when the network bandwidth is stable and promoted to 40Mbps, the server video media resources allowed for download at this bandwidth condition include 4K @ 30, 1080P @ 120, 1080P @ 60, 1080P @ 30, 720P @ 60. At this time, the client judges that the type of the video belongs to a preset type, and first determines that the currently played video media segment has a resolution of 1080P. The frame rate of the media resource at this resolution includes 120 frames, 60 frames and 30 frames. Since the TV screen refresh rate supports a maximum of 60 frames and the screen resolution is 1080P, it is determined that the media resource that meets the TV hardware playback capability under this network bandwidth is 1080P @ 60, and the client will switch to 1080 Download and play the media resources of this video in P @ 60 format.
如图6所示,为图4示例的效果展示,其中左侧图像为起播瞬间,分辨率为1080P,帧率为30的画面效果,可见画面过渡处存在模糊;右侧图像为带宽升级后采用的分辨率为1080P,帧率为60的视频画面,其和左侧图像相比画面精细度一样,但流畅度大大提升。若采用现有技术且获取分辨率为4K 帧率为30的视频媒体资源,则流畅度仍会和左侧图像一致。由该图示可见,预设类型视频场景下采用帧率优先的策略更符合用户的需求。As shown in Figure 6, it is the effect of the example shown in Figure 4, in which the left image is the starting moment, the resolution is 1080P, the frame rate is 30, the visible picture transition is blurred; the right image is after the bandwidth upgrade The video screen with a resolution of 1080P and a frame rate of 60 is the same as the picture on the left, but the fluency is greatly improved. If the existing technology is adopted and the video media resource with a resolution of 4K and a frame rate of 30 is obtained, the fluency will still be consistent with the image on the left. As can be seen from the figure, the strategy of using frame rate priority in preset type video scenes is more in line with user needs.
在第二种可能的实施方式中,当网络带宽由好变坏时,如图7所示,从服务器提供的目标视频的媒体资源中获取最高帧率下的最高分辨率媒体资源进行下载,包括:In a second possible implementation manner, when the network bandwidth changes from good to bad, as shown in FIG. 7, obtaining the highest resolution media resource at the highest frame rate from the media resource of the target video provided by the server for downloading, including :
S701、确定分辨率小于目标视频当前播放媒体资源分辨率且满足小于等于屏幕分辨率的所有媒体资源的最高分辨率为第二分辨率。S701. It is determined that the highest resolution of all media resources whose resolution is less than the currently played media resource resolution of the target video and which meets the screen resolution is less than or equal to the screen resolution is the second resolution.
S702、确定分辨率为第二分辨率的媒体资源中帧率满足小于等于屏幕刷新率的最高帧率为第二帧率。S702. It is determined that the highest frame rate in a media resource with a resolution of the second resolution that satisfies a screen refresh rate or less is the second frame rate.
S703、从服务器提供的目标视频的媒体资源中获取分辨率为第二分辨率且帧率为第二帧率的媒体资源进行下载。S703: Obtain a media resource with a second resolution and a frame rate from a media resource of the target video provided by the server for downloading.
示例性的,假设先前网络带宽条件下客户端从网络下载的媒体资源为4K@30,当网络带宽条件变差时,此时无法支持4K@30媒体资源的下载。按照现有方式服务器会提供1080P@30的媒体资源供客户端下载播放。在本实施例策略下,客户端会确定分辨率低于先前播放媒体资源4K的分辨率为1080P,然后获取服务器可提供的分辨率为1080P的媒体资源的帧率包括120帧、60帧、30帧并获取客户端自身可支持的最大屏幕刷新率为60帧,因此确定第二帧率为60帧。最后从服务提供的目标视频的媒体资源中获取分辨率为1080P,帧率为60帧的媒体资源进行下载。Exemplarily, it is assumed that the media resource downloaded by the client from the network under the previous network bandwidth condition is 4K @ 30. When the network bandwidth condition becomes poor, the download of the 4K @ 30 media resource cannot be supported at this time. According to the existing method, the server will provide 1080P @ 30 media resources for the client to download and play. Under the strategy of this embodiment, the client will determine that the resolution is lower than the resolution of the previously played media resource 4K and the resolution is 1080P, and then obtain the frame rate of the media resource that can be provided by the server with the resolution of 1080P, including 120 frames, 60 frames, 30 frames. Frame and obtain the maximum screen refresh rate that the client itself can support, so the second frame rate is determined to be 60 frames. Finally, obtain media resources with a resolution of 1080P and a frame rate of 60 frames from the media resources of the target video provided by the service for download.
在另一种可能的实施方式中,在图3所示的方法步骤基础上,如图8所示,本申请实施例还包括:In another possible implementation manner, based on the method steps shown in FIG. 3, as shown in FIG. 8, the embodiment of the present application further includes:
步骤303:若否,从服务器提供的目标视频的媒体资源中获取最高分辨率的媒体资源进行下载。Step 303: If not, obtain the highest-resolution media resource from the media resources of the target video provided by the server for downloading.
本申请实施例通过判断目标视频是否属于运动变化比较明显的类型,从而选择性地从服务器提供的目标视频的媒体资源中获取最高帧率或最高分辨率的媒体资源进行下载,从而满足了用户对高流畅度或高清晰度场景的需求。In the embodiment of the present application, by judging whether the target video belongs to a type with relatively obvious motion changes, the media resources with the highest frame rate or the highest resolution are selectively obtained from the media resources of the target video provided by the server for download, thereby satisfying the user's requirements The need for high fluency or high definition scenes.
