然而，在非Feed流场景下，当用户切换视频时，视频里APP无法基于Feed流对当前视频的后续视频进行提前缓存，因此会导致视频切换后的后续视频加载延迟、播放卡顿等问题。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
下面对本公开实施例的应用场景进行解释：
图1为本公开实施例提供的视频缓存播放方法的一种应用场景图，本公开实施例提供的视频缓存播放方法，可以应用于视频类应用客户端的非Feed流视频资源访问的场景下。本实施例提供的方法的执行主体可以为终端设备11，例如智能手机，更具体地，如图1所示，终端设备11与服务器12连接，用户通过终端设备11内运行的视频类应用客户端(以下简称客户端)，访问指定类别、条目、标识的视频分区内的视频资源，例如访问X工作室发布的所有视频资源(图1中示为video1至video6)所在的视频页(视频分区)，并点击其中任一视频资源后，播放该视频资源。之后，基于用户的滑动操作，可以将当前播放的视频切换至该视频页内的其他视频资源进行播放。
现有技术中，视频类APP中的视频切换操作，通常是基于Feed流场景的，在该场景下，用户在切换视频的过程中，客户端可以基于Feed流，提前对当前视频的后续视频进行缓存，从而使提前缓存的后续视频被切换至当前视频时，能够流畅加载和播放，然而，在非Feed流场景下，APP客户端无法基于Feed流对当前视频的后续视频进行提前缓存。例如在用户进入特定用户的视频页中点选视频进行播放时，选择的视频通常是随机的，之后当用户通过滑动操作切换视频时，滑动方向也是随机的，导致将当前视频切换至前一个视频或后一个视频，因此，无法确定缓存当前视频两侧(前一个或后一个)哪一个方向的视频资源，进而导致视频切换后的后续视频加载延迟、播放卡顿等问题。同时，若将当前视频两侧的视频资源都进行加载，则由于带宽限制，尤其是移动网络接入的条件下，会导致视频资源的缓存时间增加，一方面导致了用户流量和带宽的浪费，另一方面仍会导致后续视频播放的卡顿问题。而本公开实施例提供一种视频缓存播放方法以解决上述问题。
参考图2，图2为本公开实施例提供的视频缓存播放方法的流程示意图一。本实施例的方法可以应用于终端设备，该视频缓存播放方法包括：
步骤S101，播放视频资源序列中的第一视频。
示例性地，视频资源序列中包括多个视频，具体地，在一种可能的实现方式中，视频资源序列可以为一个播放列表，播放列表对应多个视频资源服务器内的视频播放地址，其中包括第一视频对应的视频播放地址，通过访问视频资源服务器内第一视频对应的播放地址，可以获取第一视频对应的视频数据，并将该第一视频对应的视频数据下载至终端设备本地，进行加载、转码等过程后，进行播放。在另一种可能的实现方式中，视频资源序列为一种描述信息，用于表征一个或多个视频的集合，视频资源序列可以为一个访问地址，例如“www.video.example.com/user_001”该地址下包含有多个视频文件，例如“video1”、“video2”、“video3”等。其中，示例性地，“video2”可以为视频资源序列中的第一视频。通过在视频资源序列对应的访问地址后增加视频文件的文件名，即可获得对应的视频资源。
具体地，终端设备内运行有视频类应用的客户端，基于用户的操作，终端设备通过客户端界面显示的视频资源连接，可以确定视频资源序列，并播放视频资源列表中的第一视频，客户端响应用户的点选操作，播放视频的过程为本领域技术人员知晓的现有技术，此处不再赘述。
步骤S102，当检测到针对第一视频的第一滑动操作时，根据第一滑动操作对应的滑动方向，确定视频缓存方向；其中，第一滑动操作用于将第一视频切换为视频资源序列中与第一视频相邻的第二视频进行播放，视频缓存方向表征视频资源序列中视频资源的播放方向。
示例性地，终端设备设置有用于人机交互的触摸屏，终端设备通过触摸屏检测用户对终端设备的操作行为。具体地，终端设备在通过客户端播放第一视频的过程中，当检测到第一滑动操作时，根据客户端预设的操作规则，对该滑动操作进行响应，将当前播放的第一视频切换为第二视频。其中，第一滑动操作是指在触摸屏的可操作性区域，沿屏幕的横向或纵向滑动，以切换当前播放的视频的操作，例如，向上滑动，切换至前一视频；向下滑动，切换至后一视频；或者，向左滑动，切换至前一视频；向右滑动，切换至后一视频。
其中，第二视频为视频资源序列中的视频，第二视频可以为与第一视频相邻的前一视频或后一视频；图3为本公开实施例提供的一种第二视频与第一视频的位置关系示意图，如图3所示，例如，视频资源序列中包括“video1”、“video2”、“video3”、“video4”、“video5”。第一视频为“video2”，则基于第一滑动操作对应的滑动方向，第二视频可以为“video3”或“video1”。其中，“video3”可以看作是“video2”的后一视频；“video1”可以看作是“video2”的前一视频。
进一步地，视频缓存方向是基于用户使用习惯而确定的缓存视频资源序列中的视频的方向。示例性地，视频缓存方向可以包括前向和后向，其中，前向是由当前播放的视频指向当前播放的视频的前一视频的方向，即图3所示实施例中，视频资源序列中“video1”、“video2”、“video3”、“video4”、“video5”、“video1”、……的循环方向；后向是由当前播放的视频指向当前播放的视频的后一视频的方向，即图3所示 实施例中，视频资源序列中“video5”、“video4”、“video3”、“video2”、“video1”、“video5”、……的循环方向。
其中，视频缓存方向是通过第一滑动操作对应的滑动方向，以及预设的判断规则确定的，在一种可能的实现方式中，根据第一滑动操作对应的滑动方向，确定视频缓存方向，包括：获取预设的历史滑动信息，历史滑动信息用于表征在第一滑动操作前检测到的至少一个第三滑动操作所对应的滑动方向；根据历史滑动信息和第一滑动操作对应的滑动方向，确定视频缓存方向。具体地，若第一滑动操作前连续预设次数的第三滑动操作对应的滑动方向均与第一滑动操作对应的滑动相同，则将第一滑动操作对应的滑动方向确定为视频缓存方向。例如，用户在实施第一滑动操作之前，还实施了两次第三滑动操作，第一滑动操作与两次第三滑动操作对应的滑动方向相同，即用户连续三次向一个方向实施滑动操作切换视频(即判断规则)；则将该滑动方向对应的视频播放方向，确定为视频缓存方向。其中，历史滑动信息是预设在终端设备内的，在每次检测到用户实施的滑动操作后，根据滑动操作的滑动方向，更新该历史滑动信息。
示例性地，视频缓存方向还包括待定方向；即通过第一滑动操作对应的滑动方向，以及预设的判断规则，不能视频缓存方向是前向或后向时，则确定视频缓存方向为待定方向。
步骤S103，根据视频缓存方向，确定第三视频，并对第三视频进行缓存，生成缓存视频，第三视频为视频资源序列中与第二视频沿视频缓存方向相邻的视频。
示例性地，当检测到针对第一视频的第一滑动操作时，终端设备通过运行的客户端，播放第二视频。在确定视频缓存方向后，即可根据视频缓存方向，预测后续播放的视频，即第三视频。第三视频可以为第二视频的前一视频或后一视频。
进一步地，对第三视频进行缓存，生成存储于本地的缓存视频，该缓存视频包括一个或多个视频数据，当缓存视频包括多个视频数据时，每一视频数据用于存储第三视频的一个视频片段。从而实现对全部或部分第三视频的缓存。其中，第三视频可以包括一个或多个视频，第三视频中的各视频可以对应一个或多个缓存视频，此处不对缓存视频的具体形式进行具体限定。
步骤S104，响应于针对第二视频的第二滑动操作，若第二滑动操作对应的滑动方向与视频缓存方向，播放缓存视频。
示例性地，在终端设备通过运行的客户端，播放第二视频的过程中，当用户继续切换视频时，会对终端设备实施第二滑动操作，其中，与第一滑动操作类似，第二滑动操作用于将第二视频切换为视频资源序列中与第二视频相邻的视频进行播放。图4A为本公开实施例提供的一种滑动操作与播放方向的对应关系示意图，如图4A所示，终端设备检测到第二滑动操作后，会响应第二滑动操作，对第二视频进行切换，基于第二滑动操作的滑动方向，播放第二视频的前一视频或后一视频。而基于第二滑动操作(滑动操作a)向下滑动屏幕时，播放第二视频(video2)的前一视频(video1)，对应一种播放方向(播放方向A)。图4B为本公开实施例提供的一种滑动操作与播放方向的对应关系示意图，如图4B所示，基于第二滑动操作(滑动操作b)向上滑动屏幕时，播放第二视频的后一视频(video3)，对应另一种播放方向(播放方向B)。据此，可以确定第二滑动操作与播放方向之间的对应关系。
当基于第二滑动操作对应的播放方向与视频缓存方向对应的播放方向一致时，说明预测的视频缓存方向正确，此时播放缓存的缓存视频。而在另一种可能的实现方式中，若用户实施的第二滑动操作对应的播放方向与视频缓存方向不同，或者视频缓存方向为待定方向，则不播放缓存视频，按照常规的视频加载方式进行视频的下载和播放。
在本实施例中，通过播放视频资源序列中的第一视频；当检测到针对第一视频的第一滑动操作时，根据第一滑动操作对应的滑动方向，确定视频缓存方向；其中，第一滑动操作用于将第一视频切换为视频资源序列中与第一视频相邻的第二视频进行播放，视频缓存方向表征视频资源序列中视频资源的播放方向；根据视频缓存方向，确定第三视频，并对第三视频进行缓存，生成缓存视频，第三视频为视频资源序列中与第二视频沿视频缓存方向相邻的视频；响应于针对第二视频的第二滑动操作，若第二滑动操作对应的播放方向与视频缓存方向对应的播放方向相同，则播放缓存视频。本实施例提供的方法通过检测用户的第一滑动操作，对后续的第二滑动操作对应的滑动方向进行预判，并确定对应的视频缓存方向，以该视频缓存方向对视频资源序列中的视频进行缓存，从而生成缓存视频，在用户进行第二滑动操作时，若第二滑动操作对应的播放方向与视频缓存方向对应的播放方向相同，则直接加载播放该缓存视频，提高视频加载速度，避免出现视频播放卡顿的问题。
参考图5，图5为本公开实施例提供的视频缓存播放方法的流程示意图二。本实施例中对步骤S102和S103进一步细化，该视频缓存播放方法包括：
步骤S201，播放视频资源序列中的第一视频。
步骤S202，当检测到针对第一视频的第一滑动操作时，获取预设的滑动预测模型，滑动预测模型为用于预测第一滑动操作之后的第二滑动操作对应的滑动方向的预训练模型。
步骤S203，根据滑动预测模型，确定第一滑动操作之后的第二滑动操作对应的滑动方向的置信值。
步骤S204，若置信值大于预设值，则将滑动预测模型输出的第一滑动操作之后的第二滑动操作对应的播放方向，确定为视频缓存方向。
示例性地，滑动预测模型是预训练的预测模型，用于预测用户在执行完第一滑动操作后，所执行的第二滑动操作的滑动方向。该预测模型可以基于用户的第一滑动操作的滑动方向，以及终端设备显示的第一视频、第二视频的内容、时长等信息，对用户之后将要实施的第二滑动操作的滑动方向进行预测。在一种可能的实现方式中，滑动预测模型直接输出预测的滑动方向，并将该滑动方向对应的视频资源序列中各视频的播放方向确定为视频缓存方向。在另一种可能的实现方式中，滑动预测模型直接输出预测的滑动方向的置信值。例如，前向为0.8，后向为0.2。进一步地，根据置信值，当置信值大于预设值，例如0.7时，则将滑动预测模型输出的第一滑动操作之后的第二滑动操作对应的播放方向确定为视频缓存方向。
步骤S205，根据视频资源序列，确定视频排序信息，视频排序信息用于表征视频资源序列中的各视频的位置排序。
步骤S206，根据视频排序信息，确定第二视频在视频资源序列中的位置排序。
步骤S207，根据第二视频在视频资源序列中的位置排序，以及视频缓存方向，确定第三视频。
视频排序信息是用于表征视频资源序列中各视频的位置排序的信息，在播放视频资源序列中各视频时，按照视频排序信息对应的播放顺序播放各视频。其中，示例性地，视频排序信息中可以包括视频资源序列中各视频的用于排序的标识，根据视频排序信息和第二视频的标识，可以确定第二视频在视频资源序列中的位置排序。进一步地，在确定第二视频的位置排序的基础上，基于视频缓存方向，确定视频缓存方向上与第二视频的标识相邻的标识，进而确定该标识对应的视频，即第三视频。
可选地，第三视频包括视频资源序列中的多个连续的视频，如图6所示，步骤S207包括步骤S2071、S2072两个具体的实现步骤：
步骤S2071，获取预设的缓存参数，缓存参数用于表征第三视频所包括的视频的数量。
步骤S2072，根据缓存参数，将第二视频沿视频缓存方向相邻的预设数量的视频，确定为第三视频。
示例性地，缓存参数是预设在终端设备内的信息，可以通过用户配置或者客户端安装、更新时配置在终端设备内。通过缓存参数例如包括“缓存数量＝4”，即将第二视频沿述视频缓存方向的4个视频，确定为第三视频，并在后续过程中对该4个视频进行缓存，通过本实施例中的步骤，确定多个视频为第三视频，并进行缓存，可以在用户频繁实施滑动操作切换视频时，仍保证终端设备本地缓存有视频数据，从而进一步的避免出现播放卡顿问题。
步骤S208，获取视频缓存量，并基于视频缓存量，对第三视频进行缓存，生成缓存视频。
示例性地，视频缓存量是用于表征缓存第三视频的数据量的信息，例如，视频缓存量可以是百分比数值，例如50％；也可以是具体的数据大小，例如2048kB(千字节)。通过设置视频缓存量，在对第三视频进行缓存时，仅缓存第三视频中的部分流数据，可以实现第三视频的初步缓存，之后，在确定播放第三视频时，再继续对剩余的第三视频的流数据进行缓存，即避免了视频的卡顿，又避免缓存全部的第三视频而造成的流量浪费。
在一种可能的实现方式中，获取视频缓存量，包括：
获取第一视频的内容信息，内容信息表征第一视频的视频内容类别；根据第一视频的内容信息和第一视频的播放时长，确定视频缓存量。
示例性地，内容信息是用于表征第一视频的视频内容类别的信息，例如：搞笑视频、电影视频、学习视频等。内容视频可以通过第一视频的分类标签、视频名称、视频作者标识等描述信息确定。由于用户对于不同的视频内容，感兴趣度不同。对于用户所感兴趣的视频，用户会长时间观看，而对于用户不感兴趣的视频，用户会快速切换为下一视频。因此，对于缓存的第三视频，若用户对即将播放的第三视频不感兴趣，则可能用户会很快将第三视频切换为下一视频，因此。根据第一视频的内容信息和第一视频的播放时长，确定视频缓存量，根据视频缓存量对第三视频进行少量缓存，可以节省网络带宽和流量。
在另一种可能的实现方式中，获取视频缓存量，包括：根据第一滑动操作之后的第二滑动操作对应的滑动方向的置信值，确定视频缓存量。
示例性地，第二滑动操作对应的滑动方向与第二滑动操作对应的播放方向具有固定的映射关系，通过滑动预测模型预测的第二滑动操作对应的滑动方向的置信值越大，则说明视频缓存方向与第二滑动操作对应的播放方向相同的可能性越大，反之，则视频缓存方向与第二滑动操作对应的播放方向相同的可能性越小。根据滑动预测模型预测的滑动方向的置信值，确定对应的视频缓存量，使视频缓存量与视频缓存方向与第二滑动操作对应的播放方向相同的可能性相匹配，在视频缓存方向与第二滑动操作对应的播放方向相同的可能性较小时，以较小的视频缓存量缓存第三视频；反之，则以较大的视频缓存量缓存第三视频，从而进一步的提高带宽利用率，节约流量。图7为本公开实施例提供的一种第二滑动操作对应的滑动方向的置信值与视频缓存量的对应关系的示意图，如图7所示，当滑动预测模型预测的第二滑动操作对应的滑动方向的置信值为0.8时，对第三视频进行视频缓存的数据量为2048kB，生成大小为2048kB的缓存文件；当滑动预测模型预测的第二滑动操作对应的滑动方向的置信值为0.9时，对第三视频进行视频缓存的数据量为4096kB，生成大小为4096kB的缓存文件。
步骤S209，响应于针对第二视频的第二滑动操作，若第二滑动操作对应的播放方向与视频缓存方向对应的播放方向相同，则播放缓存视频。
本实施例中，步骤S201、步骤S209的实现方式与本公开图2所示实施例中的步骤S101、步骤S104的实现方式相同，在此不再一一赘述。
