Description

一种直播视频留存的方法、装置、服务器、主播端及介质 技术领域
本发明涉及互联网技术领域，尤其涉及一种直播视频留存的方法、装置、服务器、主播端及介质。
背景技术
由于直播的现场性和强互动性，越来越多的用户选择直播来作为娱乐、培训和交流的平台。
对于直播房间的主播而言，往往希望能吸引更多观众进入直播间，并获得更多观众的响应。然而由于直播是将主播端的视频画面传实时输至对应的观众端，其在具备实时现场性的同时，也存在发挥偶然性的问题。具体来讲，由于大多是临场发挥，主播在直播过程中也往往难以预料到哪一段直播视频比较精彩，不能提前进行预告，故直播中的精彩片段只能供当时在直播房间内的观众看见，大部分观众都错过了直播过程中偶然发生的精彩瞬间。

为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。
实施例一
如图1所示，本实施例提供了一种直播视频留存的方法，所述方法应用于直播平台服务器，包括：
步骤S101，获取并保存目标直播间播放的直播视频；
步骤S102，如果在第一时刻接收到主播端发送的录制指令，则从所述直播视频中获取从所述第一时刻前的预设时长至所述第一时刻内的目标视频，其中，所述预设时长为所述主播端预先发送并存储在所述直播平台服务器的时长；
步骤S103，发送所述目标视频的描述信息至所述主播端对应的观众端；
步骤S104，接收所述观众端基于所述描述信息发送的点播指令；
步骤S105，基于所述点播指令，发送所述目标视频至所述观众端。
在本申请实施例中，所述直播平台服务器可以为计算机设备、云端或计算机设备组，在此不作限制。
下面，结合图1来详细介绍本实施例提供的直播视频留存的方法的具体实施步骤：
首先，执行步骤S101，获取并保存目标直播间播放的直播视频。
在具体实施过程中，所述主播端往往是通过直播平台服务器将实时录制的视频发送至对应的观众端进行直播的，所述对应的观众端为进入所述主播端对 应的直播间的观众端。在本申请实施例中，所述直播平台服务器会保存接收到的直播视频以供后续获取目标视频，具体的保存方式可以有多种，下面列举两种为例：
第一种，保存所述主播端从进入所述目标直播间起的所有直播视频。
具体来讲，为了便于重现主播端当次直播的所有直播视频，可以设置所述直播平台服务器会从所述主播端进入所述目标直播间起，就开始录制并保存视频，直至所主播端退出所述目标直播间。在所述主播端退出所述目标直播间后，为了节省存储空间可以删除之前保存的直播视频。
第二种，仅保存当前至所述预设时长前的直播视频。
即实时获取所述目标直播间内播放的视频；保存从当前时刻前的所述预设时长至所述当前时刻的所述直播视频。
具体来讲，为了节省存储空间，可以设置按照所述主播端预先设置的所述预设时长来进行视频的保存，即在边录制边保存的过程中，可以删除距当前时长超过预设时长的直播视频，以节约存储空间。而且在接收到主播端发送的录制指令后，可以直接以当前存储的直播视频作为所述目标视频，减少了获取所述目标视频的计算量及时长。当然，在所述主播端退出所述目标直播间后，为了节省存储空间也可以删除之前保存的直播视频。
当然，在具体实施过程中还可以采用其他的视频保存方式，例如，存储所述主播端在一天内的直播视频等，在此不作限制。
然后，执行步骤S102，如果在第一时刻接收到主播端发送的录制指令，则从所述直播视频中获取从所述第一时刻前的预设时长至所述第一时刻内的目标视频，其中，所述预设时长为所述主播端发送并存储在所述直播平台服务器的时长。
在具体实施过程中，所述主播端是在接收到录制操作后，基于所述录制操作生成所述录制指令的，具体来讲，可以是在所述目标直播间的显示页面上预先显示虚拟按钮，主播在直播过程中可以通过点击所述虚拟按钮来执行所述录制操作；也可以是预先在键盘或智能手机上设置默认的机械操作按键，主播在直播过程中可以通过压按所述机械操作按键来执行所述录制操作，在此不作限制。
在本申请实施例中，所述预设时长可以是主播预先在主播端输入，并通过所述主播端发送至所述直播平台服务器的时长；也可以是在主播执行所述录制操作后，弹出待输入窗口，再由主播在所述待输入窗口输入并发送至所述直播平台服务器的时长，在此不作限制，也不再一一列举。
进一步，所述待输入窗口可以是需要输入数字的窗口，也可以是显示有多 个时长供主播选择的窗口，在此不作限制。
在具体实施过程中，从所述直播视频中获取从所述第一时刻前的预设时长至所述第一时刻内的目标视频的方法也较多，下面列举三种为例：
第一种，按预设时长对所述直播视频进行截取。
由于所述第一时刻几乎相当于所述当前时刻，故可以截取所述直播视频中，靠后的长度为所述预设时长的视频段作为所述目标视频。
第二种，对直播视频按时间进行标识存储，截取时间段属于所述第一时刻前的预设时长至所述第一时刻内的视频。
具体来讲，在预先保持所述直播视频时，即按照视频的直播时间将直播视频分为小视频片段进行存储，并标识出每个小视频片段的直播时间。在收到录制指令后，按照标识的时间筛选出属于所述第一时刻前的预设时长至所述第一时刻的小视频片段，并组成所述目标视频。
第三种，按照所述预设时长进行保存，以所述直播视频作为所述目标视频。
即如前所述，在服务器边直播边保存的过程中，可以删除距当前时长超过预设时长的直播视频，以节约存储空间。而且在接收到主播端发送的录制指令后，可以直接以当前存储的直播视频作为所述目标视频。
当然，在具体实施过程中还可以采用其他获取目标视频的方法，在此不作限制，也不再一一列举。
接下来，执行步骤S103，发送所述目标视频的描述信息至所述主播端对应的观众端。
在本申请实施例中，所述描述信息可以包括以下任意一种或多种信息：目标视频中的截图、主播的名称、目标视频对应的直播时间或主播端发送的用于介绍所述目标视频的信息。
在本申请实施例中，所述主播端对应的观众端是指，登录直播网站，并进入所述主播端对应的直播间的观众端。
然后，执行步骤S104和步骤S105，接收所述观众端基于所述描述信息发送的点播指令；基于所述点播指令，发送所述目标视频至所述观众端。
具体来讲，所述观众端显示的所述目标直播间页面上，可以根据所述描述信息显示有虚拟窗口，观众通过点击所述虚拟窗口来执行点播操作，并生成点播指令。当所述直播平台服务器接收到所述点播指令时发送所述目标视频至所述观众端，以使所述观众端能播放所述目标视频，重现所述主播留存的精彩瞬间。
在本申请实施例中，为了给主播也提供操作权，还可以在执行所述步骤S102之后，所述直播平台服务器发送所述目标视频的所述描述信息至所述主播 端；所述直播平台服务器接收所述主播端基于所述描述信息发送的重播指令，并基于所述重播指令，发送所述目标视频至所述主播端对应的观众端。
具体来讲，通过发送所述描述信息至所述主播端，使得所述主播端的页面上根据所述描述信息显示有虚拟重播窗口，主播可以通过点击所述虚拟重播窗口执行重播操作，以生成并发送重播指令至所述直播平台服务器。直播平台服务器会基于所述重播指令发送所述目标视频至所述主播端和/或所述主播端对应的观众端进行播放，以实现主播可以控制所述目标视频的精彩瞬间在整个所述目标直播间进行统一重播，增加主播的操控类型。
具体来讲，通过直播平台服务器预先获取并保存直播视频，当主播在直播过程中发现想留存的精彩瞬间时，只需要执行简单的录制操作，就发送录制指令至直播平台服务器，直播平台服务器会按照存储的预设时长从直播视频中获取之前一段的目标视频，并发送目标视频的描述信息至观众端，以便于观众后续点播播放所述目标视频，从而实现了直播过程中精彩瞬间的录制和点播播放，使直播在具备现场性的同时也能具备精彩瞬间的重现性。
