背景技术
随着短视频应用技术的不断发展，越来越多的用户使用或观看短视频。目前，短视频的展示方式和长视频的展示方式相同，但是由于短视频的播放时长(例如小于一分钟或者几分钟)远小于长视频的播放时长(例如几十分钟或一小时以上)，基于短视频的展示特性，在各短视频之间的快速滑动切换时，每一个短视频展示之前的等待占用大量时间。

具体实施方式
下面将参照附图更详细地描述本公开的实施例。
应当理解，本公开的方法实施方式中记载的各个步骤可以按照不同的顺序执行，和/或并行执行。此外，方法实施方式可以包括附加的步骤和/或省略执行示出的步骤。本公开的范围在此方面不受限制。
本文使用的术语“包括”及其变形是开放性包括，即“包括但不限于”。术语“基于”是“至少部分地基于”。术语“一个实施例”表示“至少一个实施例”；术语“另一实施例”表示“至少一个另外的实施例”；术语“一些实施例”表示“至少一些实施例”。其他术语的相关定义将在下文描述中给出。
需要注意，本公开中提及的“第一”、“第二”等概念仅用于对不同的装置、模块或单元进行区分，并非用于限定这些装置、模块或单元所执行的功能的顺序或者相互依存关系。
需要注意，本公开中提及的“一个”、“多个”的修饰是示意性而非限制性的，本领域技术人员应当理解，除非在上下文另有明确指出，否则应该理解为“至少一个”。
通过诸如手机、平板电脑或计算机等具有显示屏的电子设备展示视频数据，上述电子设备与服务器通信连接，从服务器中加载视频数据，并在本地进行展示。同时实时监测用户对电子设备的操作，例如在显示屏上的触控操作、通过电子设备上按键输入的选择操作或者通过键盘、鼠标等输入设备输入的操作等，根据上述操作对显示的视频数据进行控制，例如上述操作可以是评论、数据上传、以及切换等。对于视频的切换操作，可以是通过在显示屏上检测到的滑动操作，或者通过电子设备上的上下按键的按压操作实现，可根据不同电子设备的实现方式输入，对此不作限定。
参见图1，图1是本公开实施例提供的视频展示过程的流程图。图1中， 当检测到任一视频被选择播放时，用户界面(User Interface，UI)线程向播放线程发送准备指令以及开始指令，由播放线程展示被选择的视频数据。在视频数据的展示过程中，UI线程可根据用户的操作向播放线程发送暂停以及停止播放的指令，以控制播放线程对视频数据的展示。当检测到停止播放操作向播放线程发送停止播放指令，或者当检测到停止播放操作向播放线程发送停止播放指令，以及释放播放线程的指令；当检测到视频数据的切换操作时，向播放线程发送停止播放指令，或者当检测到视频数据的切换操作时，向播放线程发送停止播放指令，以及释放播放线程的指令，其中，播放线程执行上述停止播放指令和释放播放线程的指令均存在等待时长。被释放的播放线程用于展示切换操作对应的下一视频数据，即在下一视频数据展示之前存在等待上一视频数据结束的时长，对下一视频数据的起播形成阻塞。尤其是在短视频的展示场景下，多个视频数据之间频繁切换，且每一个切换操作均存在等待时长。
需要说明的是，图1中使用异步线程，虽不阻塞主线程，当仍会阻塞进行播放的子线程，导致本次播放行为内核其他初始化，包括读取首帧数据等操作，被阻塞，从而增加首帧时长。
针对上述技术问题，本公开提供了一种视频的展示方法。
实施例一
图2为本公开实施例一所提供的一种视频的展示方法流程示意图，本公开实施例适用于在视频的展示过程中，对视频数据进行快速切换展示的情形，该方法可以由视频的展示装置来执行，该装置可以通过软件和/或硬件的形式实现，可选的，通过电子设备来实现，该电子设备可以是移动终端或个人电脑(Personal computer，PC)端等。
如图2，本实施例的方法包括：
S110、在检测到视频切换指令时，获取切换后的目标视频数据。
S120、基于所述目标视频数据的编码方式，确定所述编码方式对应的播放 实例，从预设实例池中调用所述播放实例。
S130、在预设线程池中调用一空闲播放线程，将所述播放实例运行在所述空闲播放线程上，以展示所述目标视频数据。
本实施例中，在视频展示的过程中，通过预加载的方式获取与正在展示的当前视频相邻的预设数量的视频数据，其中，可以是预加载在当前视频数据之前的第一数量的视频数据，以及在当前视频数据之后的第二数量的视频数据。其中，视频数据的顺序可以是根据服务器推荐的视频数据的顺序确定。预加载的视频数据的数量可以是根据当前网络状态确定，不同网络状态可以是对应不同的预加载数量，例如当前网络状态与当前网速相关，当前网速越高，当前网络状态越顺畅。可选的，预加载数量与当前网速负相关，即当前网速越高，预加载数量越少。在当前网速低的情况下，增加预加载的视频数据的数量，避免用户在视频数据的频繁切换时无法保证所切换的视频数据无法及时加载的问题，保证视频数据的快速展示；在当前网速高的情况下，减少预加载的视频数据的数量，在每一个视频数据的展示过程中，可快速对邻近的视频数据进行快速加载，同时避免预加载大量视频数据导致的流量浪费的问题。
在任一视频数据的展示过程中，可以是通过检查到的滑动操作(例如上下滑动或者左右滑动等)生成切换指令进行视频数据的切换，还可以是根据当前视频数据播放结束指令生成的切换指令进行视频数据的切换，该切换指令中可以包括切换方向，或者切换的目标视频数据的视频标识。根据切换操作确定切换的目标视频数据，示例性的，若滑动操作为向上滑动，则将当前视频数据的下一视频数据确定为目标视频数据，若滑动操作为向下滑动，则将当前视频数据的上一视频数据确定为目标视频数据。此处，目标视频数据的确定与滑动操作的功能相关，可根据预先设置的滑动操作的功能确定目标视频数据，对此不作限定。
根据目标视频数据的标识信息在预加载的本地视频库中获取该目标视频数据。可选的，维护一视频标识列表，该视频标识列表中包括预加载的视频数据 的视频标识以及预加载的视频数据的存储位置。该视频标识列表中视频标识的顺序可以是与视频数据的切换顺序相同。在检测到切换操作时，在视频标识列表确定当前视频数据的视频标识，根据切换操作的切换方向以当前视频数据的视频标识为基准确定目标视频数据的视频标识，例如切换操作为向上滑动，则确定切换为下一视频数据，将当前视频数据的视频标识的下一视频标识确定为目标视频数据的视频标识。根据该目标视频数据的视频标识对应的存储位置，获取目标视频数据。
通过预加载方式获取切换的视频数据，无需在视频切换时实时加载，节省了视频数据的加载过程，提高了视频的首帧展示效率。
不同编码形式的视频数据应用不同的播放实例。示例性的，编码方式可以是包括但不限于H.265编码和H.264编码，本实施例中，通过设置并维护一预设实例池，该预设实例池中包括多种编码形式对应的播放实例，在进行目标视频数据的展示时，从预设实例池中调用所需的播放实例，减少了在目标视频数据的展示过程中的实例化过程。
预设实例池中的播放实例可按需扩展，示例性的，若存在新增编码方式的视频数据，则将该新增编码对应的播放实例添加到预设实例池中，便于后续在展示该新增编码方式的视频数据时调用，提高了预设实例池的适用性和兼容性。
其中，预加载的视频数据中均设置有一标志位，该标志位上设置编码标识，通过读取该编码标识确定视频数据的编码方式。相应的，在获取目标视频数据之后，读取目标视频数据中的标志位的编码标识，确定目标视频数据的编码方式，基于该目标视频数据的编码方式调用对应的播放实例。该播放实例用于处理目标视频数据，例如对目标视频数据进行解码处理等。
在上述实施例的基础上，从预设实例池中调用所述播放实例，包括：若所述目标视频数据的编码方式与切换前的当前视频数据的编码方式不同，则从预设实例池中调用所述目标视频数据的编码方式对应的播放实例；若所述目标视频数据的编码方式与切换前的当前视频数据的编码方式相同，则复用所述切换 前的当前视频数据所对应的播放实例，无需重复调用正在被调用的播放实例。
在上述实施例的基础上，若所述目标视频数据的编码方式与切换前的当前视频数据的编码方式不同，则释放切换前的当前视频数据对应的播放实例。通过对切换前的当前视频数据对应的播放实例进行释放，实现对预设实例池的循环使用，减少了播放实例的创建过程。
本实施例中，预先设置一预设线程池，该预设线程池中包括至少两个播放线程，且可以循环使用，该播放线程用于展示视频数据。预设线程池中每个播放线程中可以是设置有状态标识，可通过状态标识快速确定是否被调用。例如，被调用时，状态标识可以是调用状态标识，例如为1，未被调用即处于空闲状态时，状态标识可以是空闲状态标识，例如为0。在检测到切换指令时，在预设线程池中确定空闲播放线程，即空闲状态标识的播放线程，该空闲播放线程是预设线程池中用于展示当前视频数据的线程以外的任一处于空闲状态的线程。基于该空闲播放线程展示切换的目标视频数据，无需等待切换前的当前视频数据的结束过程，即无需等待用于展示当前视频数据的线程的释放过程，加快了对目标视频数据的展示过程，提高了视频数据切换的效率。
在上述实施例的基础上，在预设线程池中调用一空闲播放线程的同时，还包括：释放切换前的当前视频数据所对应的播放线程，将被释放的播放线程设置为空闲播放线程。本实施例中，通过不同的线程处理切换前后的两个视频数据，一空闲播放线程展示切换的目标视频数据，当前被调用的线程结束正在展示的当前视频数据，上述两个过程可以是同步执行，二者相互独立，不存在相互干扰，避免了切换前的当前视频数据的结束过程阻塞目标视频数据展示的问题。
将被释放的播放线程设置为空闲播放线程，例如可以是将该播放线程的状态标识设置为空闲状态标识，该空闲播放线程可用于在下一次被调用时展示视频数据，实现预设线程池的循环使用，减少了创建线程的频率。
示例性的，参见图3，图3是本公开实施例一提供的一种视频展示过程的 示意图。预设线程池中包括播放线程0、播放线程1和播放线程2，在一些可选实施例中，不局限于图3中线程数量，还可以是两个、四个等。播放线程0用于展示当前视频数据，在UI线程检测到切换指令时，调用播放线程1播放切换的目标视频数据，同时播放线程0执行停止stop指令和释放release指令。由图3可知，播放线程1播放切换的目标视频数据与播放线程0执行停止stop指令和释放release指令的时间重叠，且互不干扰，上述播放线程0执行停止stop指令和释放release指令在后台执行，并不在显示屏上存在对象的等待过程，实现视频数据的无感知切换，提高了视频数据的切换速度和切换效率。
本实施例中，UI线程可以为主线程，UI线程用于进行播放线程的管理，执行本实施例中的视频的展示方法，例如接收用户操作生成对播放线程的指令，并将指令发送至播放线程，以控制播放线程。
可选的，对播放线程的控制通过如下方式实现：检测用户操作，根据所述用户操作向对应的至少一个播放线程的消息队列发送控制指令，以使每个播放线程依次执行对应消息队列中的控制指令。其中，每一个播放线程分别配置有一消息队列，存储缓存待执行的控制指令，多个控制指令在消息队列中先进先出，实现对该播放线程的控制，且所述至少一个播放线程之间互不干扰。示例性的，在预设线程池中调用一空闲播放线程，基于所述空闲播放线程展示所述目标视频数据，可以是向调用的空闲播放线程对应的消息队列发送视频播放指令，该视频播放指令中可以是配置有目标视频数据的视频标识。示例性的，释放切换前的当前视频数据所对应的播放线程可以是向切换前的当前视频数据所对应的播放线程对应的消息队列发送释放指令。
其中，用于控制播放线程的控制指令包括但不限于启动指令、缓存指令、暂停指令、停止指令和释放指令。示例性的，参见图3，UI线程依次向播放线程0的消息队列发送prepare指令、start指令、pause指令、stop指令和release指令，向播放线程1发送prepare指令和start指令。
在上述实施例的基础上，任一播放线程执行stop指令以及执行release指令 慢，导致该播放线程被长时间占用，在预设线程池中空闲播放线程耗尽并不能再扩充线程池(core＝＝max)，即预设线程池不存在空闲播放线程，复用前一被调用的播放线程(即最近一次被调用的播放线程)展示所述目标视频数据。
本公开实施例的技术方案，通过设置预设线程池，维护至少两个播放线程，在任一线程被调用时，该预设线程池中还包括未被调用的空闲播放线程。在视频数据的展示过程中，检测到切换指令时，在预设线程池中调用一空闲播放线程，基于空闲播放线程展示目标视频数据，无需等待已被调用的播放线程，且空闲播放线程展示目标视频数据和已被调用的播放线程进行释放互不干预，可同步执行，减少了目标视频数据展示前的等待时长，实现视频数据的无感知切换，提高了视频数据的切换速度和切换效率。同时，通过创建预设实例池，维护多种编码方式对应的播放实例，可根据目标视频数据从预设实例池中调用相匹配的播放实例，减少了创建播放实例以及实例化的过程，提高了视频数据的切换速度和切换效率。
在上述实施例的基础上，还提供了用于进行视频的展示的框架，示例性的，参见图4，图4是本公开实施例提供的用于进行视频的展示的框架图。该框架包括主线程PlaySessionManager、预设线程池playThread pool、播放会话PlaySession、消息队列PlayHandler、播放会话配置PlaySessionconfig，该框架用于播放会话和播放线程管理，其中把一个播放实例称为一次播放会话PlaySession。其中，多个播放会话PlaySession可以运行在一个播放线程playThread上，也可以各自运行在独立的播放线程playThread上。预设线程池playThread pool中包括至少两个播放线程playThread，若播放会话PlaySession超过播放线程的数量Max时，后续播放会话Session都跑在一个播放线程PlayThread上。一次只允许一个播放会话Session在Active(没有release)状态，非线程安全。预设线程池创建、回收以及在播放线程Play Thread执行完release后会回调到主线程onSessionRelease。
实施例二

其中，视频数据获取模块210，设置为在检测到视频切换指令时，获取切换后的目标视频数据；

线程调用模块230，设置为在预设线程池中调用一空闲播放线程；

在上述技术方案的基础上，该装置还包括：

在上述技术方案的基础上，该装置还包括：

根据本公开的至少一个实施例，【示例二】提供了一种视频的展示方法，还包括：
可选的，在预设线程池中调用一空闲播放线程的同时，还包括：
释放切换前的当前视频数据所对应的播放线程，将被释放的播放线程设置为空闲播放线程。
根据本公开的至少一个实施例，【示例三】提供了一种视频的展示方法，还包括：
检测用户操作，根据所述用户操作向对应的至少一个播放线程的消息队列发送控制指令，以使每个播放线程依次执行对应消息队列中的控制指令，其中，所述控制指令包括启动指令和停止指令。

可选的，若所述预设线程池不存在空闲播放线程，则复用前一被调用的播放线程展示所述目标视频数据。
根据本公开的至少一个实施例，【示例五】提供了一种视频的展示方法，还包括：
可选的，所述从预设实例池中调用所述播放实例，包括：若所述目标视频数据的编码方式与切换前的当前视频数据的编码方式不同，则从预设实例池中调用所述目标视频数据的编码方式对应的播放实例；若所述目标视频数据的编码方式与切换前的当前视频数据的编码方式相同，则复用所述切换前的当前视频数据所对应的播放实例。
根据本公开的至少一个实施例，【示例六】提供了一种视频的展示方法，还包括：
可选的，所述方法还包括：若所述目标视频数据的编码方式与切换前的当前视频数据的编码方式不同，则释放切换前的当前视频数据对应的播放实例。
根据本公开的至少一个实施例，【示例七】提供了一种视频的展示方法，还包括：
可选的，所述切换后的目标视频数据通过预加载方式获取。
根据本公开的至少一个实施例，【示例八】提供了一种视频的展示装置，该装置包括：
视频数据获取模块，设置为在检测到视频切换指令时，获取切换后的目标视频数据；
播放实例调用模块，设置为基于所述目标视频数据的编码方式，确定所述编码方式对应的播放实例，从预设实例池中调用所述播放实例，其中，所述播放实例用于处理目标视频数据；
线程调用模块，设置为在预设线程池中调用一空闲播放线程；
第一视频数据展示模块，设置为基于所述空闲播放线程展示所述目标视频数据。
此外，虽然采用特定次序描绘了各操作，但是这不应当理解为要求这些操作以所示出的特定次序或以顺序次序执行来执行。在一定环境下，多任务和并行处理可能是有利的。同样地，虽然在上面论述中包含了若干具体实现细节，但是这些不应当被解释为对本公开的范围的限制。在单独的实施例的上下文中描述的某些特征还可以组合地实现在单个实施例中。相反地，在单个实施例的上下文中描述的各种特征也可以单独地或以任何合适的子组合的方式实现在多个实施例中。
尽管已经采用特定于结构特征和/或方法逻辑动作的语言描述了本主题，但是应当理解所附权利要求书中所限定的主题未必局限于上面描述的特定特征或动作。相反，上面所描述的特定特征和动作仅仅是实现权利要求书的示例形式。
