在本实施例中，上述直播资源的播放方法可以但不限于应用于具有延时直播功能的流媒体服务器。
在步骤S202提供的技术方案中，待播放的目标直播资源可以但不限于包括视频资源，音频资源等等。比如：体育赛事视频直播，娱乐节目视频直播，新闻咨询视频直播，广播节目直播等等。
在本实施例中，目标延时信息用于指示目标直播资源在在直播过程中的延时时间，禁播内容等等。
在一种实施方式中，在获取待播放的目标直播资源和所述目标直播资源对应的目标延时信息之前，还包括：
S11，显示延时信息输入页面，其中，所述延时信息输入页面用于按照直播域名输入直播资源的延时时间和禁播内容；
S12，获取在所述延时信息输入页面上输入的具有对应关系的直播域名，延时时间和禁播内容；
S13，存储具有对应关系的直播域名和延时配置文件，其中，所述延时配置文件中记录了直播域名对应的延时时间和禁播内容。
在本实施例中，提供了一种延时信息输入页面来获取延时信息。该延时信息输入页面可以但不限于是任何类型具有延时信息输入功能的应用上的页面，比如：可以但不限于在插件、应用程序、小程序、软件上显示延时信息输入页面为直播控制人员提供控制信息的输入场景。
在本实施例中，直播资源的延时信息可以但不限于是按照直播资 源的直播域名配置的，从不同直播域名发送来的直播资源可以按照直播域名的要求配置不同的延时信息。直播域名可以但不限于包括：直播资源发送端的IP地址，URL等等。
在一种实施方式中，获取待播放的目标直播资源和所述目标直播资源对应的目标延时信息包括：
S21，接收目标域名发送的所述目标直播资源；
S22，从具有对应关系的直播域名和延时配置文件获取所述目标域名对应的目标配置文件；
S23，将所述目标配置文件中记录的目标延时时间确定为所述目标延时信息。
在本实施例中，可以但不限于按照直播域名获取相应的延时时间作为延时信息。比如：在接收各个直播域名发送的直播资源之前，预先在本地磁盘中配置并存储了各个直播域名对应的延时配置文件，在接收到某目标域名发送的目标直播资源时，从存储的延时配置文件中获取其对应的目标配置文件，将其中记录的目标延时时间确定为目标延时信息用来控制目标直播资源的延时播放。
在步骤S204提供的技术方案中，码率可以但不限于指比特率,可以表示单位时间内传送比特的数目，将目标直播资源转换为多个码率的资源流，能够快速便捷地为播放器提供不同码率的资源流，满足播放器的各种播放需求。
在步骤S206提供的技术方案中，将目标直播资源转换后得到的多个码率的资源流存储到本地磁盘服务器的本地磁盘中，能够节省从远端获取资源的时间，也能够更加精确地控制延时播放的过程，确保能够成功获取到需要播放的资源进行播放。
在一种实施方式中，将所述多个码率的资源流存储到所述本地磁盘包括：
S31，确定所述多个码率的资源流中每个码率的资源流所包括的多个资源包中的每个资源包的接收时间；
S32，在所述本地磁盘中存储所述多个码率的资源流，以及具有对应关系的资源包标识和接收时间。
在本实施例中，具有对应关系的资源包标识和接收时间作为直播资源的播放索引可以但不限于被存储在本地磁盘中。
在本实施例中，具有对应关系的资源包标识和接收时间可以但不限于以索引文件的形式存储在本地磁盘中。图3是根据本公开实施例的一种索引文件的存储过程的示意图，如图3所示，在直播开始时接收直播资源并将其转换为多个码率的资源流，在本地磁盘中存储多个码率的资源流，记录直播资源中数据包的接收时间，构建出数据包与接收时间的索引，在本地磁盘中存储该索引用于控制直播资源的延时播放过程。
在步骤S208提供的技术方案中，服务器可以但不限于自动对目标直播资源的播放时间进行监控。监控时间是否到达目标直播资源的目标播放时间的方式可以但不限于为计算当前系统时间减去目标延时时间的时间，并判断该时间是否有资源包，如果有，则确定时间达到目标播放时间。
在本实施例中，可以但不限于通过上述记录了具有对应关系的资源包标识和接收时间的索引文件来触发服务器对播放时间的监控，比如：将具有对应关系的资源包标识和接收时间以索引文件的形式存储在本地磁盘中后，服务器能够监听到索引文件有变动，当服务器监听到索引文件有变动时，则获取索引文件对应的目标直播资源的目标延时信息，并根据该目标延时信息对目标直播资源的播放时间进行监控。
在步骤S210提供的技术方案中，如果时间到了目标播放时间，则将目标码率的资源流发送给目标资源播放器进行播放。
在本实施例中，当时间达到目标播放时间时，可以但不限于根据上述索引文件以及需要播放的目标码率找到第一个应该播放的资源包，从该资源包开始依次发送之后的直播资源包给播放器进行播放。
在一种实施方式中，将所述本地磁盘中的所述多个码率的资源流中目标码率的资源流发送至所述目标直播资源的目标资源播放器包 括：
S41，按照所述目标码率的资源流所包括的资源包的接收时间从前到后，从所述本地磁盘中依次提取目标资源包；
S42，检测所述目标资源包中是否包括了所述目标配置文件中所记录的目标禁播内容；
S43，在检测到所述目标资源包中包括所述目标禁播内容的情况下，删除所述目标资源包；
S44，在检测到所述目标资源包中未包括所述目标禁播内容的情况下，将所述目标资源包发送至所述目标资源播放器。
在本实施例中，从本地磁盘中提取出目标资源包后可以对其进行禁播内容的检测，如果该目标资源包属于禁播内容，则可以将其删除不进行发送播放，如果该目标资源包不属于禁播内容，则可以进行发送播放。
在本实施例中，目标配置文件中所记录的目标禁播内容可以但不限于禁播起始时间以及禁播时长，检测目标资源包中是否包括了目标配置文件中所记录的目标禁播内容的方式可以但不限于为根据禁播起始时间与禁播时长算出禁播时间段，在发送目标资源包之前，检查该目标资源包的接收时间是否在禁播时间段内，如果在禁播时间段内，则不发送该目标资源包，继续处理下一个目标资源包。
图4是根据本公开实施例的一种检测禁播内容的过程的示意图，如图4所示，监听本地磁盘中延播配置文件有变动(生成或更新)，创建延时直播任务，获取到延时时长配置，播放码率，播放协议，计算资源流的播放起始时间，之后根据索引文件以及播放码率配置找到第一个应该播放的直播数据包，从该数据包开始，依次发送之后的直播数据包，播放器使用RTMP，HLS或者FLV协议获取直播数据包进行播放。同时还可以获取用户设置的禁播内容，包括禁播起始时间以及禁播时长。根据禁播起始时间与禁播时长算出禁播时间段，在发送直播数据包之前，检查该直播数据包的接收时间是否在禁播时间段内，如果在禁播时间段内，则不发送该数据包，继续处理下一个直播数据包。 如果不在禁播时间段内，则发送该数据包，并继续计算下一个直播数据包，直至直播结束。
在一种实施方式中，将所述本地磁盘中的所述多个码率的资源流中目标码率的资源流发送至所述目标直播资源的目标资源播放器包括：
S51，获取所述目标资源播放器所指示的所述目标码率；
S52，从所述本地磁盘存储的所述多个码率的资源流中获取所述目标码率对应的目标资源流；
S53，将所述目标资源流发送至所述目标资源播放器。
在本实施例中，资源播放器可以指定需要播放的目标码率，或者也可以根据目标资源播放器发送的当前网络状况确定适合在当前网络环境下传输的码率从而得到目标资源播放器所指示的目标码率，比如：网络状况较好时可以将较大码率确定为目标码率，网络状况较差时可以将较小码率确定为目标码率，从而使得直播资源能够更加顺畅的播放。
在一种实施方式中，将所述本地磁盘中的所述多个码率的资源流中目标码率的资源流发送至所述目标直播资源的目标资源播放器包括：
S61，从多个资源传输协议中，获取所述目标资源播放器所支持的且传输效率最高的目标资源传输协议；
S62，使用所述目标资源传输协议对所述目标码率的资源流进行编码，得到编码资源流；
S63，将所述编码资源流发送至所述目标直播资源的目标资源播放器。
在本实施例中，上述多个资源传输协议可以但不限于包括RTMP(Real Time Messaging Protocol，实时消息传输协议)，HLS(HTTP Live Streaming)，FLV(FlashVideo，流媒体格式)协议等等。
在本实施例中，根据目标资源播放器为其选择其支持的且传输效率最高的资源传输协议作为目标资源传输协议。使用该目标资源传输协议对目标码率的资源流进行编码发送，能够保证资源传输的效率较高，提高资源的播放体验。
本公开还提供了一种实施例，该实施例为提高直播资源的延时时间的准确性，提供了一种流媒体直播的延迟播放方式，可以增加延时直播长度，提高延时时间的准确性，提高延时直播的稳定性，降低流程复杂度，同时降低延时直播的成本。该方式还可以对源流码率进行转换，适应不同场景的需求，并且也可以以不同方式进行拉流，支持RTMP，HLS，FLV等多种协议，满足不同技术要求。
在该方式中，流媒体服务器接收直播资源，将直播资源存储于本地磁盘中，同时构建直播资源中各个资源包与该资源包的接收时间之间的索引。计算何时应该进行延时流的播放。达到播放时间后，根据索引找到第一个需要播放的资源包，按照配置的码率推送给客户端进行播放。在直播过程中，控制人员可通过HTTP接口设置禁止播放内容，流媒体服务器检查获取到的资源包是否为被禁止播放的内容，如果为被禁止播放的内容，则跳过该资源包。
图5是根据本公开实施例的一种直播资源延时播放过程的示意图，如图5所示，流媒体服务器可以但不限于包括以下模块：接收存储模块，设置为接收直播资源，并将其存储于本地磁盘中。记录索引模块，设置为建立直播资源与该直播资源的接收时间之间的对应关系记录到索引文件中，便于根据时间找到相应的资源包，同时也会在索引文件中记录该直播资源的延时时间。播放控制模块，设置为接收禁播命令，设置禁播时间，实现播放控制功能。查找发送模块，设置为查找需要播放的直播资源，将直播资源按照设定的码率发送给播放器。
通过上述过程，减少了将直播资源存储到分布式文件系统或者数据库带来的带宽以及存储费用等存储成本。多种码率的数据包相比固定码率数据包，存储、带宽费用成倍增长，存储于本地磁盘也可以减少这一部分的消耗。不同码率的播放可以满足观众的不同清晰度的要求。同时直播资源存储于本地磁盘，访问本地磁盘相对于访问网络数 据会快一些，提升直播延时的精准度。将直播资源存储于磁盘而不是内存中，也可以大大提升直播延时的时间长度。不同的拉流协议其适用场景不同，可以让用户选择最符合其业务需求的协议进行播放。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本公开并不受所描述的动作顺序的限制，因为依据本公开，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本公开所必须的。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台电子设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开各个实施例所述的方法。
根据本公开实施例的另一个方面，还提供了一种设置为实施上述直播资源的播放方法的直播资源的播放装置。图6是根据本公开实施例的一种直播资源的播放装置的示意图，如图6所示，该装置可以包括：
第一获取模块602，设置为获取待播放的目标直播资源和所述目标直播资源对应的目标延时信息；
转换模块604，设置为在获取到所述目标延时信息的情况下，将所述目标直播资源转换为多个码率的资源流；
