本公开所提供的视频播放方法，可以应用于如图1所示的应用环境中。其中，客户端110通过网络与服务器120进行交互。其中，客户端110可以是但不限于各种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备，服务器120可以用独立的服务器或者是多个服务器组成的服务器集群来实现。
其中，目标客户端110响应于检测到目标客户端显示预设页面，从服务器120获取与预设页面相关联的至少一个目标视频的第一配置信息和目标客户端的本地缓存信息，其中，第一配置信息包括目标视频的标识信息，目标客户端的本地缓存信息包括目标客户端已缓存的视频的标识信息，根据第一配置信息和本地缓存信息确定目标客户端的视频缓存状态，视频缓存状态用于表示目标客户端对至少一个目标视频的缓存进度，目标客户端110根据所述视频缓存状态下载缓存未完成的至少一个目标视频；响应于用户操作，播放至少一个目标视频。
图2是根据一示例性实施例示出的一种视频播放方法的流程图，如图2所示，视频播放方法应用于图1的客户端110中，包括以下步骤：
在步骤S21中，响应于检测到目标客户端显示预设页面，获取与所述预设页面相关联的至少一个目标视频的第一配置信息和所述目标客户端的本地缓存信息，其中，所述第一 配置信息包括所述目标视频的标识信息，所述目标客户端的本地缓存信息包括所述目标客户端已缓存的视频的标识信息。
在本公开实施例中，目标客户端的界面上可以包括若干视频信息组件，视频信息组件是展示视频(包括预设页面下的视频和非预设页面下的视频)相关信息的界面组件，该组件展示的内容包括一个或多个与视频相关的信息，比如，视频相关的文字、超链接、图片、概览小视频、按钮、图标等。为了便于理解，此处举例说明，如图3方框图中所示的“XXX1”、“XXX2”、“XXX3”等均为视频信息组件，当用户点击某目标视频信息组件的情况下，目标客户端响应于点击操作，进入预设页面，并获取预设页面相关联的至少一个目标视频的第一配置信息和目标客户端的本地缓存信息。
其中，第一配置信息预先存储于服务器中，每个客户端(包括目标客户端)获取到的第一配置信息都是相同的，第一配置信息包括目标视频的标识信息，目标视频的标识信息包括目标视频的视频时长和视频名称。本地缓存信息包括已缓存于本地的视频名称和视频时长，其中，本地缓存信息中的视频名称可能和第一配置信息中的视频名称相同，也可能不同。
在步骤S22中，根据所述第一配置信息和所述本地缓存信息确定所述目标客户端的视频缓存状态，所述视频缓存状态用于表示所述目标客户端对所述至少一个目标视频的缓存进度。
在本公开实施例中，可以将第一配置信息和本地缓存信息进行匹配，在本公开的一些实施例中，将第一配置信息和本地缓存信息进行匹配，可以包括：将第一配置信息中的视频名称和本地缓存信息中的视频名称进行匹配，若存储匹配的视频名称A，则表示目标客户端预先将预设页面下的视频名称A的视频缓存到本地，此时，还可以比较第一配置信息中的视频名称A的视频的视频时长和本地缓存信息中的视频名称A的视频的视频时长，从而确定本地对视频名称A的视频的已缓存容量(即该视频是否已全部缓存或部分缓存)。
为了便于理解，此处举例说明，第一配置信息包括视频名称A和对应时长2分钟，本地缓存信息包括视频名称A和对应时长1分钟，则经过第一配置信息和本地缓存信息的匹配，确定预设页面下的视频名称A的视频的视频缓存状态为部分缓存。
在步骤S23中，根据所述视频缓存状态下载缓存未完成的至少一个目标视频。
在本公开实施例中，目标客户端在确定视频缓存状态的情况下，可继续下载未完成的至少一个目标视频。
在步骤S24中，响应于用户操作，播放至少一个目标视频。
在本公开实施例中，用户操作为用户触发的操作，该用户操作用于播放目标视频，比如，该用户操作可以为用户触发的点击操作、滑动操作、选取操作等。
在本公开实施例中，当目标客户端监测到用户操作时，可以响应于用户操作，播放上述已下载缓存的至少一个目标视频。
作为一种应用场景，在某一活动期间，可能发生在瞬时涌入大量客户端进行网络视频点播的情况，因此，为了减少网络压力，降低视频播放过程中的卡顿的概率，使得客户端可以流畅清晰的观看网络视频，可以在活动开始之前，预先缓存一些相关的活动视频，从而在活动开始时，用户可以通过点击并播放已缓存的活动视频，提高活动开始时视频播放的流畅性。
上述视频播放方法，响应于检测到目标客户端显示预设页面，获取与预设页面相关联的至少一个目标视频的第一配置信息和目标客户端的本地缓存信息，其中，第一配置信息包括目标视频的标识信息，目标客户端的本地缓存信息包括目标客户端已缓存的视频的标识信息，根据第一配置信息和本地缓存信息确定目标客户端的视频缓存状态，视频缓存状态用于表示目标客户端对至少一个目标视频的缓存进度，目标客户端根据视频缓存状态下载缓存未完成的至少一个目标视频，响应于用户操作，播放至少一个目标视频，由此，实现了对视频的预缓存，上述方案可以在瞬时涌入大量客户端进行网络视频点播，对已缓存的视频不需要再从服务器进行视频缓存，直接播放本地视频，减少网络压力，降低视频播放过程中的卡顿的概率，使得客户端可以流畅清晰的观看网络视频。
在本公开的一些实施例中，步骤S21中的检测到目标客户端显示预设页面，可以包括：
检测到目标客户端在至少一个第一时间段内显示预设页面。
在本公开的一些实施例中，第一时间段可以为预设的特定时期，例如，第一时间段可以为节日、假日等特定时期。预设页面可以是为特定时期时播放的视频所制作的页面。举例而言，第一时间段可以为法定节假日，比如元旦，预设页面可以是为元旦时播放的视频所制作的页面。
其中，至少一个的个数可以为一个，或者也可以为多个。
在本公开实施例中，可以检测目标客户端是否在至少一个第一时间段内显示预设页面，当检测到目标客户端在至少一个第一时间段内显示预设页面时，可以执行步骤S21以及后续步骤。
作为一种示例，如图3所示，点击“XXX1”、“XXX2”会进入预设页面，点击“XXX3”不会进入预设页面。
在本公开的一些实施例中，步骤S23中目标客户端根据所述视频缓存状态下载缓存未完成的至少一个目标视频之前，还需要确定目标下载码率。在本公开的一些实施例中，确定目标下载码率可以包括：根据网络状态信息确定所述目标客户端的目标下载码率，所述网络状态信息包括所述目标客户端的网络状态信息和服务器的网络状态信息；步骤S23可 以包括：所述目标客户端根据所述视频缓存状态以所述目标下载码率下载缓存未完成的至少一个目标视频。
其中，目标客户端的网络状态信息可以为目标客户端的网络带宽，服务器会实时或定时根据服务器实时带宽、在线用户数、新增用户数确定服务器的网络状态信息(即网络状况)，从而确定出实时码率。实时码率是根据网络状况确定的视频下载播放的最高码率。客户端会定时从服务器获取服务器的实时码率，根据目标客户端的网络带宽和服务器的实时码率，确定目标下载码率。
在本公开的一些实施例中，根据网络状态信息确定目标客户端的目标下载码率，可以包括：
响应于所述目标客户端的网络带宽大于或等于第一预设阈值，且所述实时码率大于或等于已缓存视频的码率，将所述实时码率或所述已缓存视频的码率确定为所述目标下载码率；
响应于所述目标客户端的网络带宽大于或等于第一预设阈值，且所述实时码率小于所述已缓存视频的码率，将所述实时码率确定为所述目标客户端的目标下载码率；
响应于所述目标客户端的网络带宽小于所述第一预设阈值，将小于所述实时码率的码率确定为所述目标客户端的目标下载码率。
在本公开实施例中，在目标客户端的网络带宽大于或等于第一预设阈值，且实时码率大于或等于已缓存视频的码率的情况下，则表示客户端和服务器的网络带宽都无压力，可以将已缓存视频的码率确定为目标下载码率，按照已缓存视频的码率继续下载视频，或者，可以将实时码率确定为目标下载码率，重新下载更高清的视频；在目标客户端的网络带宽大于或等于第一预设阈值，但实时码率小于已缓存视频的码率的情况下，则表示客户端网络带宽无压力，服务器带宽可能有压力，此时，无法按照之前较高的已缓存视频的码率继续缓存视频，需要按照实时码率从服务器缓存该视频，则可以将实时码率确定为目标下载码率；在目标客户端的网络带宽小于第一预设阈值的情况下，则表示客户端的网络带宽有压力，可以将小于实时码率的码率确定为目标下载码率，其中，根据实际情况，码率通常包括480P、720P、1024P、1080P，在实时码率为720P的情况下，则小于实时码率的码率可以为480P。
在本公开的一些实施例中，在所述目标客户端根据所述视频缓存状态下载缓存未完成的至少一个目标视频之前，还可以包括：
接收服务器发送的时间配置信息，所述时间配置信息用于指示所述目标客户端下载缓存未完成的至少一个目标视频的开始时间。
在本公开实施例中，当监测到目标客户端打开应用程序APP，进入应用程序界面时， 目标客户端就会定时从服务器获取时间配置信息，该时间配置信息可能包括开始时间也可能为空，目标客户端若获取到包括开始时间的时间配置信息，可以根据时间配置信息对缓存未完成的至少一个目标视频进行缓存。
在本公开的一些实施例中，该视频播放方法还可以包括：响应于检测到目标客户端在所述第一时间段之前的时刻缓存与所述活动页面相关联的至少一个目标视频，确定所述目标视频的下载码率为所述客户端支持的最高码率，以使得所述目标客户端以其支持的最高码率缓存所述目标视频。
其中，第一时间段为预设的特定时期(例如，可以为节日等时期)，预设页面是为特定时期时播放的视频所制作的页面。第一时间段之前的时间段为非活动时段，非活动时段通常情况下服务器不会瞬时涌入大量客户端，则没有网络压力，可以按照目标客户端支持的最高码率即时下载。例如在活动开始之前，与活动页面相关的活动视频可能是已经确定的，在活动开始之前，用户打开APP时，可以提示用户缓存与活动相关的视频，经过用户同意后可以在活动开始之前缓存一些相关的活动视频，以供活动开始时播放使用，以提高活动开始时视频播放的流畅性。
图4是根据一示例性实施例示出的一种视频播放方法的流程图，如图2所示，视频播放方法应用于图1的服务器120中，包括以下步骤：
在步骤S41中，根据至少一个客户端的客户端信息和服务器的网络状态信息，对至少一个客户端进行分组，确定出至少一个目标客户端。
在步骤S42中，对所述至少一个目标客户端下发时间配置信息，所述时间配置信息用于指示所述至少一个目标客户端缓存未完成的至少一个目标视频的开始时间，使得所述至少一个目标客户端根据时间配置信息下载缓存未完成的至少一个目标视频，响应于用户操作，播放至少一个目标视频。
在本公开实施例中，用户操作为用户触发的操作，该用户操作用于播放目标视频，比如，该用户操作可以为用户触发的点击操作、滑动操作、选取操作等。
在本公开实施例中，当监测到目标客户端打开应用程序APP，进入应用程序界面时，目标客户端就会定时从服务器拉取时间配置信息，服务器也会获取到拉取时间配置信息的至少一个客户端的客户端信息和服务器的网络状态信息(即实时带宽)，其中，客户端信息包括该客户端的地理位置信息(例如，用户所在省份)和网络属性(例如，用户所属运营商网络)。然后，根据各客户端的客户端信息可以先将各个客户端进行第一次分组，例如，分成三组，第一组-A城市A运营商的客户端、第二组-A城市B运营商的客户端和第三组-B城市A运营商的客户端，进一步地，根据每组的客户端数量和服务器实时带宽，对该组中的客户端再次进行划分，得到目标客户端群体。可选的，当服务器实时带宽小于预设阈 值(实时带宽小于预设阈值表示带宽压力小)，则无论第一组中的客户端数量多还是少，都可以将第一组分成一组，当服务器实时带宽大于预设阈值(实时带宽大于预设阈值表示该服务器带宽压力大)，则无论第一组中的客户端数量多还是少，都可能需要对第一组进行分组，平均分成两组或者三组等，使得客户端可以根据时间配置信息下载缓存未完成的至少一个目标视频。当客户端监测到用户操作时，可以响应于用户操作，播放上述已下载缓存的至少一个目标视频。
应该理解的是，虽然图2、图4的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图2、图4中的至少一部分步骤可以包括多个步骤或者多个阶段，这些步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤中的步骤或者阶段的至少一部分轮流或者交替地执行。
