Description

视频直播转点播方法及系统 技术领域
本发明实施例涉及视频技术领域，尤其涉及一种视频直播转点播方法及系统。
背景技术
网络视频的播放方式分为直播和点播两种播放方式。视频直播是指随着事件的发生、发展进程，同步制作和播出视频，视频的制作和播出同时发生。视频点播是指根据用户的需求播放已制作完成的视频，视频的制作和播出非同时发生。用户在收看视频的时候，有时候可能会在直播与点播之间进行切换。例如，用户正在收看某视频网站的直播内容，但是突然想要回看之前直播中的片段以重温精彩时刻。
为了实现直播转点播的用户体验，现有技术中的解决方案是：视频服务商提供用于处理用户直播请求的直播系统和提供用于处理用户点播请求的点播系统。视频服务商的直播系统和点播系统之间通过接口进行通讯。目前，直播系统将源直播视频文件发送至点播系统。直播系统接收点播系统的点播转直播指令，根据点播系统的点播转直播指令获取源直播视频文件，并在点播系统中根据源直播视频文件生成点播文件。
发明人在实现本发明的过程中发现，通常直播转点播服务提供商在提供视频直播转点播服务时，会将直播系统和点播系统的网络传输速度看做是影响视频直播转点播的重要影响条件。视频服务提供商往往会极力优化直播系统和点播系统之间的网络传输速度，而忽略了点播系统针对所接收的点播转直播指令查询系统数据库以获取源直播视频文件所消耗的时间。
但是，在大型的网络公司中，系统数据库中所存储的源直播视频的数量可以达到百万级以上。从数量众多的源直播视频文件中查询与点播转直播指令相匹配的源直播视频文件严重消耗了系统资源，并且系统可能会反复查询处于被占用状态的源直播视频文件，严重时甚至可能导致系统崩 溃。
从数量众多的源直播视频文件中查询点播转直播指令相匹配的源直播视频文件降低了直播视频和点播视频之间的转换效率，在一种情况下，系统会反复查询处于被调占用状态的源直播视频文件。这种情况使得系统在查询的过程中耗费了大量的时间。通过实际工作测试结果可知，当从数量级为百万条的源视频文件中查询其中一个源直播视频并生成相应的点播视频时，点播系统的响应时长能达到十秒以上。这就拖后了待转换的源直播视频所对应的点播视频的生成时间，严重影响了用户体验。
发明内容
本发明实施例提供一种视频直播转点播方法及系统，用以解决现有技术中视频直播转点播速度过慢的缺陷，提高了视频直播转点播的速度。
本发明实施例提供一种视频直播转点播方法，其特征在于，包括：
接收直播转点播请求，解析出待点播视频的视频特征参数；
查询索引表，所述索引表保存所述源直播视频文件的视频特征参数和存储地址的对应关系，确定与所述待点播视频的视频特征参数对应的视频文件的存储地址；
根据所确定的视频文件的存储地址找到相应的源直播视频文件；
利用所述相应的源直播视频文件生成点播文件。
本发明实施例提供一种视频直播转点播系统，其特征在于，包括：
直播转点播检索单元，用于接收直播转点播请求，解析出待点播视频的视频特征参数；查询索引表，所述索引表保存所述源直播视频文件的视频特征参数和存储地址的对应关系，确定与所述待点播视频的视频特征参数对应的视频文件的存储地址；利用所确定的视频文件的存储地址找到相应的源直播视频文件；
点播文件生成单元，用于利用所述相应的源直播视频文件生成点播文件。
通过本发明实施例提供的视频直播转点播方法及系统，通过建立含视频特征参数和存储地址的索引表，根据所接收的直播转点播请求中所包含的视频特征参数查询所述索引表获取源直播视频文件，相比于现有技术中的根据所接收的直播转点播请求查询系统数据库中的多个源直播视频文件获取源直 播视频文件，实现了避免对系统数据库的全局检索查询，同时也避免了反复查询系统数据库中处于被占用状态的源直播视频文件，减少了视频直播转点播过程对系统的资源消耗并有效降低了在直播转点播过程中系统崩溃的可能性；
