具体实施方式
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。
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。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，调用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。此外，在本公开实施例的描述中，除非另有说明，“多个”的含义是指两个或两个以上。
相关技术中，终端设备接收到用户的视频播放操作需要从推荐服务器获取包含视频下载地址的推荐信息，然后再根据视频下载地址从视频资源服务器下载视频才能进行视频的播放，而从推荐服务器获取推荐信息和从视频资源服务器下载视频均会有网络延时和传输耗时，两次网络延时和传输耗时的叠加会导致终端设备的视频播放延时很长，非常影响用户的使用体验。
有鉴于此，本公开实施例提供了一种视频播放方法及装置，用于缩短终端设备的视频播放延时。
以下首先对本公开实施例提供的视频播放方法的场景架构进行说明。
参照图1所示，本公开实施例提供的视频播放方法的场景架构中包括：终端设备11、服务器12、推荐服务器13以及资源服务器14。
其中，终端设备11上安装有视频播放应用程序，响应用户输入，通过视频播放应用程序，能够进行视频的播放；服务器12可以为终端设备11响应于终端设备的请求向终端设备提供视频播放数据；推荐服务器13保存有预定义的推荐算法，可以响应于推荐请求，确定推荐视频以及返回推荐视频的下载地址；资源服务器14保存有所有视频的播放数据，其它设备(终端设备或服务器)可以根据视频下载地址从资源服务器获取对应视频的播放数据。
当终端设备11接收到用户输入的控制播放器进行视频播放的操作时，终端设备11向服务器12发送视频推荐请求信息。服务器12接收到终端设备11发送的视频推荐请求信息时，首先向推荐服务器13发送用于请求推荐服务器13返回推荐视频的请求信息，并接收推荐服务器13发送的至少一个推荐视频的下载地址，然后根据至少一个推荐视频的下载地址从资源服务器14获取第一视频的播放数据，再根据至少一个推荐视频的下载地址和第一视频的播放数据生成视频推荐响应信息，以及将视频推荐响应信息返回终端设备11。终端设备11接收到视频推荐响应信息后，获取视频推荐响应信息中携带的第一视频的播放数据，并基于所述第一视频的播放数据开始进行视频播放。终端设备11还根据所述至少一个推荐视频的下载地址从资源服务器14获取所述至少一个推荐视频的播放数据以及根据所述至少一个推荐视频的播放数据进行后续视频播放。
本公开实施例中的终端设备11可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)、智能手表、智能手环等终端设备，或者该终端设备11还可以为其他类型的终端设备，本公开实施例不作限定。本公开实施例中的服务器12可以为应用程序服务器，例如：终端设备11接收到控制安装在终端设备11的应用程序A启动以进行视频播放的操作，则服务器12可以为应用程序A的服务器。
需要说明的是，图1所示场景架构中以服务器12、推荐服务器13以及资源服务器14分别为独立的硬件设备为例示出，但本公开实施例并不限定于此，在一些实施例中，将服务器12、推荐服务器13以及资源服务器14中的两个或两个以上集成硬件设备同一硬件设备中。例如：将服务器12和推荐服务器13集成到一个硬件设备中。此外，资源服务器14可以为单个服务器，也可以为服务器集群。
在上述内容的基础上，本公开实施例提供了一种视频播放方法，参照图2所示，该视频播放方法包括如下步骤S21至S26：
S21、终端设备响应于视频播放操作，向服务器发送视频推荐请求信息。
对应的，服务器接收终端设备发送的视频推荐请求信息。
本公开实施例中的视频播放操作可以是用于启动视频播放应用程序的操作，例如：对视频播放应用程序的图标的输入，或者是控制启动视频播放应用程序的语音输入；本公开实施例中的视频播放操作也可以是用于切换视频频播放应用程序正在播放的视频的输入，例如：在终端设备的视频播放界面中输入的向下滑动输入。此外，视频播放操作具体可以是用户对虚拟控件的点击操作或者是用户输入的语音指令，或者是用户输入的特定手势。在本公开的一些实施例中，所述特定手势可以为单击手势、滑动手势、压力识别手势、长按手势、面积变化手势、双按手势、双击手势中的任意一种。
需要说明的是，视频推荐请求信息还可以携带终端设备的标识信息和/或终端设备的登录用户的标识信息，以使服务器可以根据终端设备的标识信息和/或终端设备的登录用户的标识信息进行视频推荐。
S22、服务器获取至少一个推荐视频的下载地址和第一视频的播放数据。
在一些实施例中，终端设备可以向推荐服务器发送携带有终端设备的标识信息和/或终端设备的登录用户的标识信息的请求信息，以便推荐服务器根据预设定的推荐算法确定推荐视频，以及将推荐视频的下载地址返回服务器。
在一些实施例中，第一视频可以为所述至少一个推荐视频中的一个。例如：第一视频可以为推荐视频中的第一个视频。
在一些实施例中，第一视频还可以为服务器缓存的终端设备或终端设备的登录用户对应的视频。即，服务器针对每一个用户或终端设备进行视频缓存，当接收到终端设备发送的视频推荐请求信息时，根据缓存数据获取对应的第一视频的播放数据。
在一些实施例中，第一视频的播放数据包括第一视频的全部视频帧对应的播放数据。即，第一视频的播放数据完整包括第一视频的全部播放数据。
在一些实施例中，第一视频的播放数据包括第一视频的前预设数量个视频帧对应的播放数据。即，第一视频的播放数据仅包括第一视频的部分播放数据。
S23、服务器根据所述至少一个推荐视频的下载地址和所述第一视频的播放数据生成视频推荐响应信息。
即，服务器生成的视频推荐响应信息中不但包括所述至少一个推荐视频的下载地址，而且还包括所述第一视频的播放数据。
S24、服务器向终端设备发送所述视频推荐响应信息。
对应的，终端设备接收所述服务器发送的所述视频推荐响应信息。
S25、终端设备解析所述视频推荐响应信息，获取所述第一视频的播放数据。
即，终端设备从所述视频推荐响应信息中提取所述第一视频的播放数据。
S26、终端设备基于所述第一视频的播放数据开始进行视频播放。
本公开实施例提供的视频播放方法在终端设备响应于视频播放操作向服务器发送视频推荐请求信息后，接收所述服务器发送的包括至少一个推荐视频的下载地址和第一视频的播放数据的视频推荐响应信息，然后解析所述视频推荐响应信息，获取所述第一视频的播放数据以及基于所述第一视频的播放数据开始进行视频播放。由于本公开实施例提供的视频播放方法在向服务器发送视频推荐请求信息后，接收到的视频推荐响应信息包括第一视频的播放数据，因此本公开实施例可以获取所述第一视频的播放数据并基于所述第一视频的播放数据开始进行视频播放，相比于相关技术中接收服务器发送的推荐视频的下载地址后，先下载推荐视频然后才能开始进行视频播放，本公开实施例只需通过一次网络请求即可开始进行视频播放，减少了网络延时和传输耗时，因此本公开实施例可以缩短终端设备的视频播放延时。
还需要说明的是，相关技术中，在视频播放过程中，终端设备要进行两次网络请求(一次用于请求推荐视频的下载地址，另一次用于请求推荐视频的播放数据)，而两次网络请求均有一定几率失败，且其中任一次网络请求失败都会导致视频播放失败，因此相关技术中视频播放的失败概率较大。本公开实施例中终端设备只要进行一次网络请求即可以开始进行视频播放，因此本公开实施例还可以减少视频播放的失败概率。
本公开实施例提供了另一种视频播放方法，参照图3所示，该视频播放方法包括如下步骤：
S301、终端设备响应于视频播放操作，向服务器发送视频推荐请求信息。
对应的，服务器接收所述终端设备发送的视频推荐请求信息。
S302、服务器从推荐服务器获取至少一个推荐视频的下载地址。
在一些实施例中，上述步骤S302(服务器从推荐服务器获取至少一个推荐视频的下载地址)的实现方式可以包括如下步骤a和步骤d：
步骤a、服务器向推荐服务器发送携带有目标用户的标识的请求信息。
其中，所述目标用户为所述终端设备的登录用户，所述请求信息用于请求推荐服务器 返回对应的推荐视频的下载地址。
步骤b、推荐服务器根据所述目标用户的标识，获取所述目标用户的属性信息。
其中，目标用户的属性信息可以包括目标用户的视频观看历史、目标用户的视频观看偏好等信息。
步骤c、推荐服务器根据所述目标用户的属性信息和预定义推荐算法，确定至少一个推荐视频。
上述步骤c(推荐服务器根据所述目标用户的属性信息和预定义推荐算法，确定所述至少一个推荐视频)的实现方式可以包括：
推荐服务器根据所述目标用户的属性信息和预定义推荐算法确定视频资源库中的各个视频的推荐度，并按照推荐度对视频资源库中的视频进行降序排序，以及将排序结果中的前n个视频确定为所述至少一个推荐视频，其中，n为正整数。
步骤d、推荐服务器向所述服务器发送所述至少一个推荐视频的下载地址。
S303、服务器从所述至少一个推荐视频中确定所述第一视频。
在一些实施例中，上步骤S303(服务器从所述至少一个推荐视频中确定所述第一视频)包括：
服务器将所述至少一个推荐视频中的第一个推荐视频确定为所述第一视频。
即，将所述至少一个推荐视频中排序最靠前的视频(推荐度最大的视频)确定为所述第一视频。
S304、服务器根据所述第一视频的下载地址从资源服务器获取所述第一视频的播放数据。
由于服务器从推荐服务器获取了所述至少一个推荐视频中的每一个视频的下载地址，且所述第一视频是由服务器在所述至少一个推荐视频中确定的，因此服务器可以获取所述第一视频的下载地址，进而根据所述第一视频的下载地址从资源服务器获取所述第一视频的播放数据。
在一些实施例中，上述步骤S304(服务器根据所述第一视频的下载地址从资源服务器获取所述第一视频的播放数据)，包括：
服务器根据所述第一视频的下载地址从资源服务器获取所述第一视频所有视频帧对应的播放数据。
即，服务器从资源服务器完整获取了所述第一视频全部内容对应的播放数据。
在一些实施例中，在服务器根据所述第一视频的下载地址从资源服务器获取了所述第一视频所有视频帧对应的播放数据的情况下，终端设备无需再根据第一视频的下载地址从资源服务器获取第一视频的播放数据，因此本公开实施例提供的方法还可以包括：
将所述第一视频的下载地址从所述至少一个推荐视频的下载地址中删除。
在一些实施例中，上述步骤S304(服务器根据所述第一视频的下载地址从资源服务器获取所述第一视频的播放数据)，包括：
服务器根据所述第一视频的下载地址从所述资源服务器获取所述第一视频的前预设数量个视频帧对应的播放数据。
即，服务器从资源服务器仅获取了所述第一视频的部分内容对应的播放数据。
在服务器根据所述第一视频的下载地址从所述资源服务器获取所述第一视频的前预设数量个视频帧对应的播放数据的情况下，终端设备还需再根据第一视频的下载地址从资源服务器获取第一视频的前预设数量个视频帧之后的其它视频帧对应的播放数据，因此所述至少一个推荐视频的下载地址中需要保留所述第一视频的下载地址。
S305、服务器根据所述至少一个推荐视频的下载地址和所述第一视频的播放数据生成视频推荐响应信息。
在一些实施例中，上述步骤S305(服务器根据所述至少一个推荐视频的下载地址和所述第一视频的播放数据生成视频推荐响应信息)，包括如下步骤1和步骤2：
步骤1、按照预设格式对所述至少一个推荐视频的下载地址和所述第一视频的播放数据进行合并，生成合并数据。
其中，预设格式可以由服务器与终端设备预先约定，或者由运维人员预先配置。
步骤2、根据所述合并数据生成所述视频推荐响应信息。
S306、服务器向终端设备发送所述视频推荐响应信息。
对应的，终端设备接收服务器发送的视频推荐响应信息。
S307、终端设备解析所述视频推荐响应信息，获取所述第一视频的播放数据和所述至少一个推荐视频的下载地址。
在一些实施例中，终端设备可以按照所述预设格式对所述视频推荐响应信息进行解析，从而获取所述第一视频的播放数据和所述至少一个推荐视频的下载地址。
如上所述，在一些实施例中，所述至少一个推荐视频的下载地址中包括所述第一视频的下载地址，在一些实施例中，所述至少一个推荐视频的下载地址中不包括所述第一视频 的下载地址。
S308、终端设备基于所述第一视频的播放数据开始进行视频播放。
在上述步骤S304中，若服务器根据所述第一视频的下载地址从所述资源服务器获取了所述第一视频的前预设数量个视频帧对应的播放数据(第一视频的部分播放数据)，则执行如下步骤S309至S312，而若服务器根据所述第一视频的下载地址从所述资源服务器获取了所述第一视频的全部视频帧对应的播放数据(第一视频的全部播放数据)，则跳过步骤S309和S310，直接执行如下步骤S311和S312。
S309、终端设备根据所述第一视频的下载地址获取所述第一视频的前预设个视频帧之后的其它视频帧对应的播放数据。
S310、终端设备将所述第一视频的前预设个视频帧之后的其它视频帧对应的播放数据缓存到所述第一视频的前预设个视频帧对应的播放数据之后。
S311、终端设备根据所述至少一个推荐视频的下载地址获取所述至少一个推荐视频对应的播放数据。
S312、终端设备将所述至少一个推荐视频对应的播放数据缓存到所述第一视频的播放数据之后。
需要说明的是，上述步骤S309至S312与上述步骤S308可以是同步执行的，即，终端设备基于所述第一视频的播放数据开始进行视频播放的同时，开始进行后续播放数据的获取。
本公开实施例提供的视频播放方法在终端设备响应于视频播放操作向服务器发送视频推荐请求信息后，接收所述服务器发送的包括至少一个推荐视频的下载地址和第一视频的播放数据的视频推荐响应信息，然后解析所述视频推荐响应信息，获取所述第一视频的播放数据以及基于所述第一视频的播放数据开始进行视频播放。由于本公开实施例提供的视频播放方法在向服务器发送视频推荐请求信息后，接收到的视频推荐响应信息包括第一视频的播放数据，因此本公开实施例可以获取所述第一视频的播放数据并基于所述第一视频的播放数据开始进行视频播放，相比于相关技术中接收服务器发送的推荐视频的下载地址后，先下载推荐视频然后才能开始进行视频播放，本公开实施例只需通过一次网络请求即可开始进行视频播放，减少了网络延时和传输耗时，因此本公开实施例可以缩短终端设备的视频播放延时。
网络请求均会有一定的失败概率，而若本公开实施例中的网络请求失败(终端设备向 服务器发送视频推荐请求信息失败或终端设备接收所述服务器发送的视频推荐响应信息失败)，则会导致终端设备无法开始进行视频的播放。为了解决该问题，本公开实施例提供了一种进行异常兜底的方案，具体包括：
若终端设备在预设时长内未接收到所述服务器发送的所述视频推荐响应信息，则读取预设存储空间中存储的第二视频的播放数据，并基于所述第二视频的播放数据开始进行视频播放。
即，终端设备向服务器发送视频推荐请求信息后，服务器很久都没有进行响应，则读取缓存的第二视频的播放数据，并基于所述第二视频的播放数据开始进行视频播放，从而进一步在网络请求异常时，缩短终端设备的视频播放延时。
终端设备基于所述第一视频的播放数据开始进行视频播放时也可能会出现异常，例如：播放数据中缺少或丢失了第一视频的码率、分辨率等必要数据。本公开实施例同样对此类异常进行了兜底，具体包括：
若基于所述第一视频的播放数据对所述第一视频进行播放出现异常，则读取预设存储空间中存储的第二视频的播放数据，并基于所述第二视频的播放数据开始进行视频播放。
即，虽然收到了服务器返回的视频推荐响应信息，但无法基于所述第一视频的播放数据开始进行视频播放，此时读取缓存的第二视频的播放数据，并基于所述第二视频的播放数据开始进行视频播放，从而进一步在通过网络请求获取的播放数据异常时缩短终端设备的视频播放延时。
在正常获取了推荐视频的播放数据后，本公开实施例提供的视频播放方法还包括：
根据推荐视频的播放数据对第二视频进行更新。
例如：在某一时刻，终端设备获取了推荐视频A的播放数据，但尚未对推荐视频A进行播放，但用户停止了通过终端设备进行视频播放，则可以将视频A更新为所述第二视频。
基于同一发明构思，作为对上述方法的实现，本公开的一些实施例还提供了一种终端设备和一种服务器，该实施例与前述方法实施例对应，为便于阅读，不再对前述方法实施例中的细节内容进行逐一赘述，但应当明确，以下实施例中的终端设备和服务器能够对应实现前述方法实施例中的全部内容。
