附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明实施例中记载的一些实施例，对于本领域普通技术人员来讲，还可以根据这些附图获取其他的附图。

具体实施方式
为了使本领域的人员更好地理解本发明实施例中的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地 描述，显然，所描述的实施例仅是本发明实施例一部分实施例，而不是全部的实施例。基于本发明实施例中的实施例，本领域普通技术人员所获取的所有其他实施例，都应当属于本发明实施例保护的范围。
图1是本发明一实施例的视频播放方法的流程示意图，可应用于手机、电脑等多种可实现视频播放功能的终端中。如图1所示，一种视频播放方法包括：
步骤S101，根据视频播放请求，获取视频流。
本实施例中，视频播放请求中可以携带所请求的视频流的信息，例如视频标识、名称、地址等，根据该视频播放请求获取相对应的视频流。
本实施例中，视频流的存储位置及传输方式不限，例如，存储位置可以为进行视频播放终端的本地硬盘、移动存储装置、网络服务器等；传输方式可以为网络传输、数据线传输、蓝牙无线传输等。
步骤S102，获取视频流解码后的视频帧，以及视频流的内容特征信息。
本实施例中，对视频流的解码方式不限，将视频流解码后可获得多个视频帧，视频帧可在播放器中被播放。
本实施例中，视频流的内容特征信息用于表征视频流的内容特征，是对视频内容分析后获得的结果，其中，进行视频内容分析的对象及分析方法不限。例如，可通过图像分析对视频流中所包括的图像信息进行内容识别，并获取内容特征信息；或者通过语音分析对视频流中所包括的音频信息进行内容识别，并获取内容特征信息。
本实施例中，视频流的内容特征信息数量及种类不限，在获取前可根据需求进行自定义设置。一项视频流的内容特征信息可对应于视频流解码后的全部视频帧，也可对应于视频流解码后的部分视频帧。例如，当视频流的内容特征信息为特定明星姓名时，对应的是图像中包括特定明星的视频流解码后的视频帧。相应的，视频流解码后的一个视频帧中可包括任意数量的视频流的内容特征信息。例如，小猫和小狗各自为一项视频流的内容特征信息， 视频流解码后的一个视频帧中包括小猫和小狗，则该视频帧包括两项内容特征信息。
本实施例中，视频流的内容特征信息的记录方式不限，可以是文字、布尔值或者任何可以体现视频内容特征的信息或值。例如，通过图像分析可识别出视频流解码后的一个视频帧中所包括的全部人物或者物品对象，视频流的内容特征信息可以被记录为全部人物对象的姓名，也可以用0或1记录是否包括特定的人物对象。
步骤S103，根据视频流的内容特征信息，控制视频流解码后的视频帧的播放。
本实施例中，视频流中全部或者部分内容特征信息与视频帧播放控制指令存在对应关系，当视频流解码后的一个或者多个视频帧中包括特定的视频流的内容特征信息时，可根据该特定视频流的内容特征信息获取对应的播放控制指令，从而利用播放控制指令控制对应的视频帧播放，即一个播放控制指令可控制一个或者多个视频流解码后的视频帧播放。
例如，如果视频流解码后的一个特定视频帧中包括视频流中的第一内容特征信息，第一内容特征信息对应的视频播放控制指令为停止播放，则当播放器播放到该特定视频帧时便会停止播放。
具体的，由于视频观看者、播放器开发方和运营方、集成播放器的应用程序开发方和运营方、嵌入播放器的网页运营方等视频播放关联方都有可能按照各自需求控制视频的播放过程，因此各视频播放关联方均可根据需求设置视频流中全部或者部分内容特征信息对应的播放控制指令。
具体的，播放视频流解码后的视频帧的播放器种类不限，例如，独立的播放器程序、集成在应用中的播放器、嵌入在网页中的播放器等。
具体的，用于执行播放控制指令的程序种类不限，执行播放控制指令的程序可安装在进行视频播放的本地终端上，或者与本地终端通过网络连接的外部终端上。例如，对视频流解码后的视频帧进行播放的播放器、集成播放 器的应用、用于呈现嵌入播放器的网页的浏览器等。
由以上本发明实施例可见，本发明首先根据视频播放请求，获取视频流；然后获取视频流解码后的视频帧，以及视频流的内容特征信息；从而根据视频流的内容特征信息，控制视频流解码后的视频帧的播放。因此，本发明实施例可以通过视频内容特征信息设定视频流解码后的视频帧播放规则，实现根据不同需求进行个性化自动播放控制的效果。
图2是本发明另一实施例的视频播放方法的流程示意图，如图2所示，一种视频播放方法包括：
步骤S201，根据视频播放请求，获取视频流。
步骤S202，获取视频流解码后的视频帧，以及视频流的内容特征信息。
本实施例中，由于视频流中会包括大量与视频内容相关的信息，但是可能只有很少一部分会成为视频流的内容特征信息，用于控制视频帧的播放。因此为了减少数据处理量，提高内容特征信息的获取效率，可首先设置或者获取视频帧播放控制规则，视频帧播放控制规则用于指示视频流的内容特征信息与视频帧播放控制指令的对应关系；然后根据视频帧播放控制规则，确定仅与视频帧播放控制指令对应的视频流的内容特征信息范围，从而获取对应的视频流的内容特征信息。
本实施例中，由于视频编码是按“视频帧组”进行，每一组包括关键帧、前后参考帧等，对应地，对每组视频帧组进行解码后，每一组会包括多个视频帧，因此视频流解码前的一个关键帧可对应于视频流解码后的多个视频帧。因此可通过图像分析，从视频流解码前的至少一个视频关键帧或者视频流解码后的至少一个视频帧中，获取视频流的内容特征信息。例如，可分析视频流解码前的全部关键帧或者视频流解码后的全部视频帧中所包括的明星，将明星的姓名作为视频流的特征信息。
具体的，如果视频流的内容特征信息是通过视频流解码前的一个关键帧 获取的话，可利用通过该关键帧获取的视频流内容特征信息，控制该关键帧对应的解码后的多个视频帧播放。
具体的，可根据设备的数据处理能力或者播放控制的准确度要求，确定获取视频流的内容特征信息的图像检测及信息提取策略。例如，当系统可分配给用于进行视频流的内容特征信息提取的资源有限，或者无需对每一视频帧都进行精准播放控制时，可仅对视频流解码前的关键帧或者解码后的部分视频帧进行图像检测，并根据检测结果获取视频流的内容特征信息。
步骤S203，将视频流的内容特征信息通过接口传输至播放控制端。
本实施例中，播放控制端是视频播放的多家关联方根据需求，设定视频帧播放控制规则或直接发送播放控制指令的设备。播放控制端可以为播放视频流解码后的视频帧的本地终端，或者为通过网络、数据线等方式与本地终端连接的外部终端。
本实施例中，为了便于不同视频播放的关联方利用播放控制端获取视频流的内容特征信息，可将视频流的内容特征信息进行组装，例如利用JS引擎组装成自定义的JS对象；然后通过特定的接口供播放控制端，即将视频流的内容特征信息通过接口传输至播放控制端。
步骤S204，获取播放控制端根据视频流的内容特征信息发送的播放控制指令。
本实施例中，不同的播放控制终端可根据各自的需求，设置视频流中全部或者部分内容特征信息与视频帧播放控制指令的对应关系。当播放控制端获取的视频流内容特征信息存在对应的视频帧播放控制指令时，可发送对应的视频帧播放控制指令。
步骤S205，根据播放控制指令，控制视频流解码后的视频帧的播放。
本实施例中，控制视频流解码后的视频帧的播放包括下述步骤中的至少其一：
启动视频流解码后的视频帧的播放；
停止视频流解码后的视频帧的播放；
调节视频流解码后的视频帧的播放时长；
对视频流解码后的视频帧进行图像处理。
截取视频流解码后的视频帧。
具体的，启动视频流解码后的视频帧的播放是指从特定视频帧开始按序列播放视频流解码后的多个视频帧，或者仅播放特定视频帧。例如，如果用户仅希望观看电影中特定明星出场后的部分，播放控制端可通过视频流的内容特征信息确定包括特定明星的第一个视频帧，然后通过播放控制指令控制从该视频帧开始对视频帧进行逐帧播放。
具体的，停止视频流解码后的视频帧的播放是指从特定视频帧开始停止按序列播放视频流解码后的多个视频帧，或者停止播放特定视频帧。例如，如果电影中存在暴力内容，播放控制端可通过视频流的内容特征信息确定包括暴力内容的第一个视频帧，然后通过播放控制指令控制从该视频帧开始停止播放视频帧。
具体的，调节视频流解码后的视频帧的播放时长是指延长或缩短特定视频帧的播放时间。例如，如果视频观看者希望查看电影中快速飞行子弹的运动轨迹，播放控制端可通过视频流的内容特征信息确定包括飞行子弹的至少一个特定视频帧，然后通过播放控制指令将特定视频帧的单帧播放时长从0.01秒调整为1秒或其它，从而放慢该视频帧的播放速度，延长播放时间。
具体的，截取视频流解码后的视频帧是指对至少一个特定视频帧进行图像截取，获得多个图片或者由多个特定视频帧组成的一段视频内容。例如，视频观看者希望在播放视频时将某一特定明星出现的画面进行截图保存的话，播放控制端通过视频流的内容特征信息确定包括该特定明星的至少一个特定视频帧，然后通过播放控制指令将包括特定明星的特定视频帧进行截图保存。
具体的，为了实现提高视频播放的趣味性、个性化投放广告、屏蔽不良内容等需求，对视频流解码后的视频帧进行图像处理包括下述步骤中的至少 其一：
编辑视频流解码后的视频帧中的至少一个对象；
在视频流解码后的视频帧中增加至少一个对象；
获取实时采集的真实场景视频帧，将实时采集的真实场景视频帧与视频流解码后的视频帧进行融合。
具体的，编辑视频流解码后的视频帧中的至少一个对象是指对视频帧图像中的全部或者部分内容对象进行图像编辑处理。例如，当根据内容特征信息确定直播、短视频、电影、电视剧等视频资源中包括色情暴力内容对象的特定视频帧时，对这些视频帧可使用模糊滤镜方式全部模糊后渲染，或者仅将特定视频帧中的色情暴力内容对象进行模糊后渲染，又或者从图像中直接去除特定视频帧中的色情暴力内容对象。
具体的，在视频流解码后的视频帧中增加至少一个对象是指根据视频流的内容特征信息，确定需要增加对象的视频流解码后的视频帧和/或所需增加的对象在视频流解码后的视频帧中的位置，利用图像处理技术在视频流解码后的视频帧中增加新的对象。例如，根据视频流内容特征信息确定所需增加对象的特定视频帧，在特定视频帧中的右上角增加希望推广的产品图标；根据视频流内容特征信息确定包括特定人物对象的视频帧及特定人物对象在视频帧中的位置，为视频帧中的特定人物对象添加帽子图像、卡通耳朵图像等。
具体的，将实时采集的真实场景视频帧与视频流解码后的视频帧进行融合是指根据视频流的内容特征信息，首先确定需要与实时采集的真实场景视频帧进行融合的视频流解码后的视频帧和/或视频流解码后的视频帧中的对象；然后通过摄像头、照相机等图像采集装置实时拍摄真实场景，获取真实场景视频帧；将实时获取的真实场景视频帧中的全部或者部分对象与视频流解码后的视频帧中的全部或者部分对象融合后进行显示播放。例如，根据视频流内容特征信息确定特定人物出现的视频流解码后的视频帧及在视频帧中的位置，用通过摄像头实时采集的真实场景中的人物替换视频流解码后的视 频帧中的特定人物。
由以上本发明实施例可见，本发明可以将视频流的内容特征信息通过接口传输至视频播放关联方的播放控制端；可获取播放控制端根据视频流的内容特征信息发送的播放控制指令；从而根据播放控制指令，控制视频流解码后的视频帧的播放。因此，本发明实施例可以仅检测并获取一次视频流的内容特征信息，供多个播放控制端用于根据不同需求控制视频流解码后的视频帧的播放。
图3是本发明再一实施例的视频播放方法的流程示意图，如图3所示，一种视频播放方法包括：
步骤S301，根据视频播放请求，获取视频流。
步骤S302，获取视频流解码后的视频帧。
步骤S303，将视频流解码后的视频帧通过接口传输至播放控制端。
本实施例中，由于不同视频播放的关联方利用播放控制端设备控制视频播放时，所需的视频流的内容特征信息会有所不同，因此进行视频播放的本地终端可将视频流解码后的视频帧进行组装，例如利用JS引擎组装成自定义的JS对象；然后通过特定的接口，供播放控制端获取，即将视频流解码后的视频帧通过接口传输至播放控制端。
步骤S304，获取播放控制终端根据视频流解码后的视频帧发送的视频流的内容特征信息。
本实施例中，播放控制终端通过对视频流解码后的全部或者部分视频帧进行图像分析后，可根据自身的播放控制需求生成视频流的内容特征信息，然后将视频流的内容特征信息传输至播放控制端。
步骤S305，根据视频流的内容特征信息，控制视频流解码后的视频帧的播放。
本实施例中，进行视频播放的本地终端首先设置或者获取视频帧播放控 制规则；然后根据视频帧播放控制规则，利用从播放控制端获取的视频流的内容特征信息确定视频流解码后的视频帧的播放控制指令；从而通过播放控制指令控制视频流解码后的视频帧播放。
由以上本发明实施例可见，本发明可以由进行视频播放的本地终端将视频流解码后的视频帧通过接口传输至播放控制端；由播放控制端根据需求提取所需的视频流的内容特征信息，并传输给进行视频播放的本地终端；从而进行视频播放的本地终端可根据视频流的内容特征信息，控制视频流解码后的视频帧的播放。因此，本发明实施例可以降低视频播放的本地终端的数据处理量，节约系统资源。
