本申请涉及网络通信技术领域，特别涉及视频播放方法。本申请同时涉及视频播放装置，一种计算设备，以及一种计算机可读存储介质。
背景技术
随着直播平台业务的增长，观看直播的用户也在增加。目前，用户观看的直播流分为原始流和转码流，由于原始流是主播的原始推流，因此参数规格和码率上限都不相同，发明人意识到，在用户想要观看高画质直播时，由于部分用户的网络差、带宽低的问题，导致用户观看直播时会出现卡顿的现象，因此，如何在不降低用户观看画质的情况下，减少用户观看时的卡顿是目前亟需解决的问题。
发明内容
有鉴于此，本申请实施例提供了视频播放方法。本申请同时涉及视频播放装置，一种计算设备，以及一种计算机可读存储介质，以解决现有技术中存在的网速差的用户无法拥有良好的观看体验的问题。

具体实施方式
在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似推广，因此本申请不受下面公开的具体实施的限制。
在本申请一个或多个实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请一个或多个实施例。在本申请一个或多个实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。 还应当理解，本申请一个或多个实施例中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请一个或多个实施例中可能采用术语第一、第二等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请一个或多个实施例范围的情况下，第一也可以被称为第二，类似地，第二也可以被称为第一。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
首先，对本申请一个或多个实施例涉及的名词术语进行解释。
视频流：音视频数据的传输流，视频流能够被作为一个稳定连续的流通过网络传输给观众，以使观众能够观看到该视频。
码率：视频数据传输时单位时间传送的数据位数，码率越高则视频画面越清晰，码率越低视频画面越模糊。
帧率：用于测量显示帧数的量度，即刷新率，测量单位为每秒显示帧数。
默认清晰度：观众观看视频时，视频提供方默认分配给用户的不同码率的视频流，即不同的清晰度。
原画：视频提供方推送的原始视频流。
转码流：经过转码系统用算法优化，将原始视频流编码优化，尽可能保持相同观看体验并降低码率。
在现有的观看视频体系中，视频流分为原始流和转码流，用户通过客户端观看视频时，客户端会拉取该视频的视频流，通过解析视频流获得该视频的视频文件，从而进行观看。但是不同的用户客户端所使用的带宽不同，即网速有快慢区分，因此，视频提供方会针对视频流进行转码处理，生产出多种不同码率的视频流，例如，将原画视频流转换成低码率的高清视频流、超清视频流等，以使用户能够根据网速选择对应的清晰度，可有效降低用户的直播卡顿使播放更加流畅，又可以降低视频提供方的带宽成本。
但是，在实际应用中，当用户想要观看清晰度更高的视频时，往往由于用户的低带宽、网速差等原因，导致用户观看时出现视频卡顿、使得用户观看体验差，因此，视频提供方需要主动为用户解决上述问题，给用户提供更好的观看环境。
基于此，在本申请中，提供了视频播放方法，本申请同时涉及视频播放装置，一种计算设备，以及一种计算机可读存储介质，在下面的实施例中逐一进行详细说明。
图1示出了根据本申请一实施例提供的一种视频播放方法的流程图，具体包括以下步骤：
步骤102：接收初始视频的窗口调整指令，其中，所述窗口调整指令用于调整所述初始视频的窗口大小。
其中，初始视频可以理解为用户当前正在观看的视频，窗口调整指令可以理解为调整初始视频的窗口的指令，窗口调整指令中可以包含有想要调整的窗口信息，根据窗口调整指令可以将初始视频的窗口调整到用户想要的窗口大小，例如，当时初始视频的窗口为800*600，用户想要观看1440*900的视频，则会向用户客户端发出窗口调整指令，用户端接收到窗口调整指令之后，将初始视频调整至1440*900的窗口。
在实际应用中，在视频的码率相同，即清晰度不变的情况下，窗口越大，用户观看的视频越模糊，相应的，在窗口不变的情况下，视频的码率越高，则用户观看到的视频越清晰，但是，由于视频码率的提高，相对的对用户的带宽要求也同样提高。
基于此，本申请提供一种视频播放方法，在用户通过窗口化观看视频的情况下，降低视频码率，为其提供消耗带宽更少的视频流，在用户全屏观看视频的情况下，为其切换至画质更高的视频流，虽然用户通过窗口化观看视频时的视频流码率低，但是由于窗口化播放，用户的清晰度观感不变；在用户全屏观看时，为其提供画质更高的视频流，保证用户的观看体验不会受到影响。
在本申请一具体实施例中，用户在观看视频A时，想要调整视频A的窗口大小，则会点击窗口调整按钮，用户客户端此时会接收到窗口调整指令，用户客户端在接收到窗口调整指令之后，将视频A的窗口调整至用户想要观看的尺寸，即将视频A的窗口调整至用户期望的观看窗口大小。
在实际应用中，当用户通过网页观看一个视频时，会点击该视频，则向用户客户端发出针对待观看视频的观看指令，用户客户端经过相关处理之后，为用户提供待观看视频的播放。
具体地，接收初始视频的窗口调整指令之前，还包括：
接收对应待观看视频的观看指令；
根据所述观看指令获取所述待观看视频的默认视频流地址；
基于所述默认视频流地址播放所述待观看视频。
其中，待观看视频可以理解为用户准备观看的视频，观看指令可以理解为观看待观看视频的指令，观看指令中可能会携带有视频的标识信息，用户客户端在接收到观看指令之后，则会为用户提供待观看视频的播放功能。
默认视频流地址可以理解为视频提供方为用户提供的默认观看视频的视频流地址，用户客户端可以根据视频流地址拉取对应的视频流。例如，用户通过网页观看一个视频时，会默认的为用户提供窗口大小为800*600的高清(码率1500)视频，用户客户端根据默认视频流可以获取到待观看视频的视频文件，从而为用户进行播放。
在本申请一具体实施例中，沿用上例，用户通过网页准备观看视频A时，点击视频A的播放按钮，此时用户客户端接收到针对待观看视频的观看指令，用户客户端根据该观看指令获取到待观看视频的默认视频流地址，根据该默认视频流，用户客户端会在默认大小窗口下播放视频A，视频A的码率为1500千位每秒(kbps)。
在实际应用中，用户客户端通过服务器获取默认视频流地址，具体地，根据所述观看指令获取所述待观看视频的默认视频流地址，包括：
根据所述观看指令生成观看请求，并将所述观看请求发送至服务器；
接收所述服务器响应于所述观看请求发送的视频流地址集合；
根据所述观看指令在所述视频流地址集合中确定默认视频流地址。
其中，观看请求可以理解为用户客户端观看待观看视频的请求，在用户客户端接收到观看指令之后，则会向服务器发送观看请求，观看请求中可以携带有用户客户端标识信息、用户客户端的带宽信息、视频标识信息等，基于观看请求，服务器会发送待观看视频对应的视频流地址给客户端，以使客户端能够播放待观看视频。
在实际应用中，一个视频的视频流地址会有多个，不同的视频流地址对应的码率不同，服务器在接收到视频的原始流之后，会根据原始流转码成多个转码流，例如，标清(码率800)，高清(码率1500)，超清(码率2500)，蓝光(码率4000)，这些转码流可以理解为一压视频流，以使用户客户端能够根据当前带宽选择合适的码率的视频流并进行播放；并且，服务器还会针对每种码率进行二次压缩，生成每个码率对应的二压视频流，为用户客户端在窗口化播放视频时，提供带宽消耗更少的视频流，使用户在观看视频时不会出现卡顿，并且在用户感官上，视频画质也没有减少。
在本申请一具体实施例中，用户客户端根据观看指令生成观看请求，并将观看请求发送至服务器，服务器在接收到观看请求之后，会发送视频A的视频流地址集合至用户客户端，视频流地址集合中包括有高清、超清、原画的一压视频流地址和高清、超清、原画的二压视频流地址，用户客户端会根据观看指令在视频流地址集合中确定默认视频流地址，即选择默认大小窗口下对应码率的视频流地址，从而为用户提供在该窗口下，观看体验最好且不会出现卡顿现象的视频流地址。
具体地，根据所述观看指令在所述视频流地址集合中确定默认视频流地址，包括：
根据所述观看指令获取所述待观看视频的默认窗口信息；
根据所述默认窗口信息确定默认视频流地址。
其中，默认窗口信息可以理解为用户观看视频时，视频的默认窗口，例如，在用户打开一个视频准备观看时，用户客户端会为其提供一个默认窗口的视频进行播放，可以理解为用户客户端会为其提供一个默认窗口大小的视频进行播放。
在实际应用中，用户客户端会根据默认窗口信息，确定一个默认视频流地址，默认视频流地址对应的视频在该窗口下播放的画质清晰、且不会出现播放卡顿的现象，可以理解为用户客户端在带宽、窗口固定的情况下，为用户提供的一个直播观看体验较好的视频流地址。
在本申请一具体实施例中，用户客户端根据观看指令获取待观看视频的默认窗口信息，默认窗口信息为1280*1024，则用户客户端根据默认窗口信息确定默认视频流地址为码率1500的视频流地址，且由于是窗口化观看，因此该视频流地址可以是高清码率对应的二压视频流地址。相较于高清码率的一压视频流地址，二压视频流地址码率有所降低，但是在窗口化模式观看的情况下，用户的观看体验不变。
步骤104：根据所述窗口调整指令确定目标窗口信息和目标视频流地址。
在用户观看视频的过程中，若用户调整了视频的窗口，则用户客户端需要根据用户期望的窗口，重新确定一个视频流地址，为用户提供画质更清晰的视频，从而不会影响用户的观看体验。
其中，目标窗口信息可以理解为用户期望的视频窗口信息，即视频在经过窗口调整之后的窗口，目标视频流地址可以理解为在目标窗口信息下，视频对应的视频流地址。
在实际应用中，用户在窗口化观看的情况下，用户客户端根据窗口的大小确定视频画质，也即窗口确定视频流的码率，因此，在窗口调整的情况下，用户客户端会重新确定一个适合当前窗口的码率的视频流地址，从而在不影响用户观看画质的情况下，为其提供一个不会出现卡顿的视频流地址进行播放。
在本申请一具体实施例中，沿用上例，用户客户端根据窗口调整指令确定出目标窗口信息为1440*900，目标视频流地址为超清的视频流的地址。
具体地，根据所述窗口调整指令确定目标窗口信息和目标视频流地址，包括：
获取所述窗口调整指令中的目标窗口信息；
根据所述目标窗口信息确定所述目标窗口信息对应的视频码率信息；
根据所述视频码率信息确定目标视频流地址。
其中，视频码率信息可以理解为视频流对应码率信息，在实际应用中，用户客户端获取窗口调整指令中携带的目标窗口信息，根据目标窗口信息确定目标窗口信息对应的视频码率信息，根据视频码率信息可以确定出对应的目标视频流地址。
在本申请一具体实施例中，沿用上例，获取窗口调整指令中的目标窗口信息，目标窗口信息为1440*900，根据目标窗口信息确定目标窗口信息对应的视频码率信息为超清(码率2500)，根据视频码率信息确定目标视频流地址为码率2500的视频流对应的视频流地址。
具体地，根据所述视频码率信息确定目标视频流地址，包括：
根据所述视频码率信息确定与所述视频码率信息对应的目标视频流地址集合，其中，所述目标视频流地址集合中包括至少一个视频流地址，且每个视频流地址对应的视频流的编码策略不同；
根据所述目标窗口信息在所述目标视频流地址集合中确定目标视频流地址。
其中，目标视频流地址集合中的视频流地址对应的视频流，对应的视频码率信息相同，但是每个视频地址对应的视频流的编码策略不同。
在实际应用中，服务器会为用户客户端提供一压视频流地址和二压视频流地址，用户客户端不仅会选择目标窗口对应的码率的视频流，还会根据目标窗口信息确定是用一压视频流地址还是二压视频流地址，二压视频流相较于一压视频流，在窗口化模式观看情况下，清晰度与一压视频流不会有明显区别，但是拉取二压视频流消耗的带宽更少，因此，在窗口化模式下选择二压视频流进行观看，在全屏模式下选择一压视频流进行观看，从而实现在不影响用户观看体验的前提下，用户观看时带宽消耗更少，不会出现卡顿的现象。
具体地，根据所述目标窗口信息在所述目标视频流地址集合中确定目标视频流地址，还包括：
在所述目标窗口信息为设备最大窗口的情况下，在所述目标视频流地址集合中选择一压视频流地址作为目标视频流地址；
在所述目标窗口信息为非设备最大窗口的情况下，在所述目标视频流地址集合中选择二压视频流地址作为目标视频流地址。
其中，目标窗口信息为设备最大窗口可以理解为用户将窗口切换至全屏，在全屏观看的情况下，为用户提供清晰度更高的一压视频流地址进行拉流播放；标窗口信息为非设备最大窗口可以理解为用户通过窗口化进行观看，在窗口化观看的情况下，通过二压视频流地址进行拉流，为用户播放画质无差别的视频。
在实际应用中，用户会调整视频的窗口，则用户客户端会根据窗口动态调整视频流的码率，并且根据窗口是否为设备最大窗口，选择相对码率下的一压视频流或二压视频流，实现了通过动态调整视频码率为用户提供最佳观看体验。
在本申请一具体实施例中，沿用上例，在目标窗口为设备最大窗口的情况下，选择该窗口对应的码率的一压视频流地址进行拉流播放。
在本申请另一具体实施例中，沿用上例，在目标窗口为非设备最大窗口的情况下，选择该窗口对应的码率的二压视频流地址进行拉流播放。
具体地，在所述目标窗口信息为非设备最大窗口的情况下，根据所述目标窗口信息在所述目标视频流地址集合中确定目标视频流地址，还包括：
根据所述目标窗口信息在所述目标视频流地址集合中确定至少两个压缩视频流地址；
根据所述用户客户端的属性信息在至少两个压缩视频流地址中确定目标视频流地址。
其中，压缩视频流地址可以理解为二压视频流地址，在至少两个压缩视频流地址中对应的两个压缩视频流的压缩策略不同，在实际应用中，压缩视频流可以是264视频流或者265视频流，264视频流是通过H.264编码压缩策略压缩视频流获得的，265视频是通过H.265编码压缩策略压缩视频流获得的，具体压缩策略根据实际情况确定，本申请在此不作具体限制。
在实际应用中，根据设备能够支持播放的视频流确定压缩视频流，例如，部分设备只能够支持解析264视频流，则确定264视频流的地址为目标视频流地址。在具体实施时，会优先判断设备是否能够支持265视频流的解析，在设备不支持265视频流的解析的情况下，选择264视频流进行拉流播放。
在本申请一具体实施例中，沿用上例，目标窗口不是设备的最大窗口的情况下，用户客户端在目标视频流地址集合中确定目标窗口对应的两个压缩视频流地址，分别为264视频流地址和265视频流地址，根据用户客户端的属性信息确定265视频流地址为目标视频流地址。
步骤106：将所述初始视频的初始视频流地址切换为所述目标视频流地址。
其中，在用户客户端确定目标视频流地址之后，则可以将当前正在播放的初始视频的初始视频流地址切换为目标视频流地址，根据目标视频流进行播放。
在实际应用中，用户客户端在切换视频流地址时，同时会获取初始视频的播放进度信息，以使在切换至目标视频流地址之后，根据目标视频流地址播放视频时，用户能够继续观看相同的视频进度，从而保证用户的观看体验。
在本申请一具体实施例中，沿用上例，用户客户端确定目标视频流地址为超清的二压视频流地址，根据该二压视频流地址进行该视频的播放。
步骤108：基于所述目标视频流地址播放与所述目标窗口信息对应的目标视频，其中，所述初始视频与所述目标视频播放内容相同且码率不同。
其中，目标视频可以理解为基于目标视频流地址进行拉流播放的视频，目标视频与初始视频为同一个视频，即播放内容相同，但是码率不同即清晰度不同。
在实际应用中，用户客户端可以基于目标视频流地址进行拉流播放目标视频，目标视频可以根据初始视频的播放进度继续播放。
在本申请一具体实施例中，沿用上例，用户客户端基于目标视频流地址播放与目标窗口信息对应的目标视频，目标视频与初始视频的播放内容都是视频A，但是目标视频与初始视频的码率不同。
具体地，基于所述目标视频流地址播放与所述目标窗口信息对应的目标视频，包括：
根据所述目标视频流地址获取并解析目标视频流；
根据解析结果和所述目标窗口信息播放目标视频。
在实际应用中，用户客户端会根据目标视频流地址获取到视频流，通过解析视频流为用户进行播放。
在本申请一具体实施例中，沿用上例，用户客户端根据目标视频流地址获取到目标视频流，目标视频流为超清的视频流，用户客户端解析目标视频流，并以目标窗口进行播放，即在用户调整的视频大小尺寸下进行播放。
本申请提供的一种，视频播放方法，应用于用户客户端，包括：接收初始视频的窗口调整指令，其中，所述窗口调整指令用于调整所述初始视频的窗口大小；根据所述窗口调整指令确定目标窗口信息和目标视频流地址；将所述初始视频的初始视频流地址切换为所述目标视频流地址；基于所述目标视频流地址播放与所述目标窗口信息对应的目标视频，其中，所述初始视频与所述目标视频播放内容相同且码率不同。通过根据视频的窗口动态调整播放视频的清晰度，实现在用户网络差的情况下，为用户提供合适画质的视频，优化用户观看体验，同时降低视频提供方的带宽成本。
下述结合附图2，以本申请提供的视频播放方法在观看直播的应用为例，对所述视频播放方法进行进一步说明。其中，图2示出了本申请一实施例提供的一种应用于观看直播的视频播放方法的处理流程图，具体包括以下步骤：
步骤202：接收初始直播视频的窗口调整指令，其中，所述窗口调整指令用于调整所述初始直播视频的窗口大小。
其中，初始直播视频可以是全屏观看模式下的直播视频，也可以是窗口观看模式下的直播视频。
在实际应用中，在用户通过网页进入直播间观看直播时，直播平台会为用户提供一个窗口化观看的直播视频，在用户想要全屏观看时，用户点击屏幕上的全屏按钮，用户客户端则会接收到窗口调整指令，调整窗口至设备最大窗口。用户进入直播间观看直播时，直播平台服务器会为用户客户端提供一个视频流集合，当该直播间对应的主播为满足判断主播是否为大主播条件时，视频流集合中包括有原始视频流、对原始视频流压缩的一压视频流以及对一压视频流压缩的二压视频流。主播是否为大主播条件可以是根据主播的粉丝人数判断，也可以是根据主播的直播时长判断，本申请在此不作具体限制。
在本申请一具体实施例中，用户进入直播间进行观看直播，直播平台服务器此时会为用户客户端提供一个视频流地址集合，用户客户端在视频流地址集合中确定默认视频流地址，默认视频流地址为二压视频流地址，用户客户端基于该二压视频流地址进行拉流播放，使得用户在窗口化模式观看的前提下，也能够观看到画质清晰的直播，此时播放的直播视频即为初始直播视频。在用户想要全屏观看直播时，用户会点击全屏按钮，用户客户端此时会接收到针对初始直播视频的窗口调整指令，调整窗口为设备最大窗口。
步骤204：根据所述窗口调整指令确定目标窗口信息和目标直播流地址。
在本申请一具体实施例中，沿用上例，用户客户端根据窗口调整指令确定目标窗口信息为设备最大窗口，和设备最大窗口对应的目标直播流地址，此时目标直播流地址为一压视频流地址。
