Description

流媒体频道录制、回看方法、装置、服务器及存储介质 技术领域
本发明涉及互联网视频播放技术领域，尤其涉及一种流媒体频道录制方法及装置、回看方法及装置、服务器及存储介质。
背景技术
苹果公司提出的互联网电视流媒体(HTTP Live Streaming，HLS)规范，已经大量运用在HLS频道直播业务上，同时各种传统网络电视(Internet Protocol Television，IPTV)的频道时移回看业务也用HLS进行了实现。
现有技术中，在对HLS频道直播码流进行录制时，通常将容量巨大的媒体文件分割成数量众多的小分片文件，并以小分片文件为单位存入文件***。在进行HLS频道回看时，将划分成数量众多的小分片文件传递给终端，迎合了网页服务器的文件传输特性，并且采用一个不断更新的轻量级索引文件来控制分割后小分片文件的下载和播放，可同时支持直播和点播。此外，文件分割和索引文件的引入也使得带宽在自适应码流间切换、服务器故障冗余切换和文件加密保护等变得更加方便。
但是HLS频道回看业务常规情况下常常需要部署100多个频道，每个频道基本上有3个码率，每个码率一般10秒中生成一个小分片，回看的时长一般设置为7天。按照最低码率512Kbps计算，则总共需要存放18144000个小分片文件，最小文件大小是640KB。大量的小分片文件存入文件***，导致文件***存储了过多的文件数目，从而提高了对该文件***的存储要求和成本。此外，在进行流媒体频道回看的过程中，因为文件***存入大量的小分片文件，使得用户在获取小分片文件时磁盘的读取速度大大降低，基本上只能发挥一半的数据吞吐能力；同时在进行信息检索时因为文件数 量过大，导致检索效率较低，相应的检索准确率也受到很大影响。

具体实施方式
为了在进行流媒体频道回看录制时降低录制所需的文件数目，进而大幅降低对文件***存储文件数目的需求，使得小分片文件存储成本也相应降低。下面通过具体实施方式结合附图对本发明作进一步详细说明。
实施例一：
请参考图1，图1为本实施例提供的流媒体频道录制方法流程图。
在本实施例中，流媒体频道录制方法具体步骤如下：
S11，根据录制任务从流媒体源站获取对应的小分片文件；
S12，将获取的小分片文件按预设聚合规则存储于聚合文件中，所述聚合文件存储于文件***；并将所述小分片文件在所述聚合文件中的描述信息存储于信息描述库中。
通过上述步骤，使得在对小分片文件进行录制时就将小分片文件按预设的聚合规则存入聚合文件，同时小分片文件往文件***中存储时是以聚合文件为单位，从而降低了录制所需的文件数目，同时也很方便找到合适的文件***来存放录制的文件。
进一步的，上述提到的信息描述库既可存放于文件***，也可存放于数据库中亦或其他地方。
此外，上述提到的录制任务是从管理装置中获取到的，并将录制任务存入信息描述库，定时从该信息描述库中获取所有的录制信息；该录制任务包括频道号和流媒体源站主索引文件地址信息等，通过频道号和流媒体源站主索引地址信息，获取主索引文件，并对主索引文件进行解析，得到该频道下的码率信息和子索引文件下载地址信息；根据子索引文件下载地址信息，得到该频道该码率下的各子索引文件；对各子索引文件进行解析，得到该频道该码率下各小分片文件下载地址信息，最后依次访问各小分片文件下载地址信息，获取小分片文件。
进一步的，上述预设聚合规则有如下几种方式：预设聚合规则有累积播放时长聚合规则、存入分片累积个数聚合规则和存入分片累积占用字节聚合规则。对于累积播放时长聚合规则，将小分片文件依次存入聚合文件，当存入的小分片文件累积播放时长等于预设累积播放时长阈值时，将后续的小分片文件存入下一聚合文件中；对于存入分片累积个数聚合规则，将小分片文件依次存入聚合文件，当存入的小分片文件累积个数等于预设累积个数阈值时，将后续的小分片文件存入下一聚合文件中；对于存入分片累积占用字节聚合规则，将将小分片文件依次存入聚合文件，当存入的小分片文件累积占用字节等于预设累积占用字节阈值时，将后续的小分片文件存入下一聚合文件中。上述的阈值均可根据实际情况进行配置，同时，上述的三种预设聚合规则均是将许多小分片文件聚合成一个大文件进行存储，这种聚合规则并不限定于上述三种，也可以通过其他方式进行聚合，聚合机制类似，对于其他聚合规则，也在本实施例保护的范围内，这里不再详细赘述。在本实施例中，优选地，采用累积播放时长的聚合规则对小分片文件存储。
进一步的，请参见图2，图2为本实施例提供的文件***中小分片文件聚合前后的文件存储对比示意图。图2中，现有技术将小分片文件直接存储于文件***，而本实施例将多个小分片文件通过聚合文件整合成一个大的文件存储于文件***中，从而减小各文件***的文件数目。
进一步的，小分片文件依次按照字节偏移量存入聚合文件，其存储方式如下：
假设第一个小分片文件的起始值为0，所有小分片文件的字节偏移量均为2，将第一个小分片文件存放于聚合文件中，再将第二小分片文件存入其中，该小分片文件起始值为2，依次类推，直到聚合文件达到***设定的存储阈值N。新建另一个聚合文件，继续将后续的小分片文件存入新建的聚 合文件，该聚合文件中第一个小分片文件的起始值依然为0，按照之前聚合文件的存储方式，依次将各小分片文件存入新建的聚合文件中，直到该聚合文件达到***设定的存储阈值N。此外，小分片文件按照字节偏移量进行存储的方式不限于上述方式，也可通过其他方式实现小分片文件按字节偏移量存储，对于其他存储方式，也在本实施例保护的范围内，这里不再详细赘述。
进一步的，在S12中提到的描述信息包括频道号、码率、在聚合文件中的字节偏移量信息、小分片文件的存储路径和起止时间，通过该信息在与终端用户进行交互时，可方便快捷的检索到所需信息。
此外，请参考图3，图3为本实施例提供的聚合文件老化删除过程示意图。图3中，假设聚合文件的回看时长为4天，Day1存储了A个小分片文件，当前回看时长是5天，故需要老化删除Day1中的聚合文件，也就是说当录制的聚合文件超过***设定回看的时长时，就会执行老化删除超过期限的聚合文件和信息描述库中对应小分片文件的描述信息，具体的老化删除过程如下：
获取预设的有效期回看时长阈值，根据所述有效期回看时长阈值和所述各小分片文件的描述信息确定出在所述有效期回看时长阈值之前的老化小分片文件，并从所述文件***中删除与所述老化小分片文件对应的聚合文件；所述老化小分片文件为超过有效期回看时长阈值需要被删除的文件。
在对聚合文件进行老化删除时，存在聚合文件中的部分小分片文件需要被老化删除，如图3所述，F4聚合文件跨越了Day1和Day2，老化删除时只需删除处于Day1部分的小分片文件，对应的描述信息也要被老化删除。也就是说根据对应的各小分片文件描述信息中的起止时间判断哪些小分片文件需要被老化删除；对于聚合文件刚好整个被老化删除时，根据最后一个小分片文件播放结束时间判断哪些聚合文件需要被老化删除。
实施例二：
请参考图4，图4为本实施例提供的流媒体频道回看方法流程图。
本实施例在实施例一的基础上，对流媒体频道回看方法进行说明，其具体步骤如下：
S41，接收终端发送的频道回看请求，该频道回看请求包括文件定位信息；
S42，根据所述文件定位信息，从通过如权利要求1-6任一项所述的流媒体频道录制方法得到的信息描述库中定位出对应的小分片文件在所述文件***中的资源位置信息；
S43，将所述资源位置信息发送给所述终端以供该终端获取对应的小分片文件进行播放。
对于上述步骤，本实施例通过匹配实施例一中存储的小分片文件及其描述信息，定位出终端所需的小分片文件描述信息，使得终端能准确获取所需小分片文件进行播放，从而提高了流媒体频道回看服务的磁盘输入/输出吞吐能力。
进一步的，上述步骤中提到的文件定位信息包括频道号、码率和起止时间；信息描述库包括小分片文件在所述聚合文件中的描述信息，该描述信息包括频道号、码率、在聚合文件中的字节偏移量信息、小分片文件的存储路径和起止时间；资源位置信息包括总字节偏移量和第一个小分片文件的存储路径。这里的总字节偏移量是指，根据终端发送的请求，在信息描述库中找到对应的小分片描述信息，通过第一个小分片文件描述信息中的字节偏移量信息和最后一个小分片文件的描述信息中的字节偏移量，得到终端请求的小分片文件总字节偏移量信息。
此外，请参考图5，图5为本实施提供的根据终端请求在文件***和信息描述库中的信息匹配流程图。该信息匹配的具体步骤如下：
S51，将所述文件定位信息中的频道号与所述信息描述库中描述信息的频道号进行匹配，得到该频道下的小分片文件描述信息；
S52，将所述文件定位信息中的码率与所述该频道下的小分片文件描述信息中的码率进行匹配，得到该频道该码率下的小分片文件描述信息；
S53，将所述文件定位信息中的起止时间与所述该频道该码率下的小分片文件描述信息中的起止时间进行匹配，得到该频道该码率该起止时间段内的小分片文件描述信息；
S54，根据所述该频道该码率该起止时间段内的每个小分片文件描述信息中的字节偏移量信息和小分片文件存储路径，计算出所述该频道该码率该起止时间段内小分片文件的总字节偏移量，并查找出所述该频道该码率该起止时间段内第一个小分片文件的存储路径；
S55，根据所述总字节偏移量和第一个小分片文件的存储路径，从所述文件***中定位出对应的小分片文件的具***置。
实施例三：
请参考图6，图6为本实施例提供的流媒体频道录制装置示意图。
在本实施例中，流媒体频道录制装置包括：
获取模块61，配置为根据录制任务从流媒体源站获取对应的小分片文件；
处理模块62，配置为将获取的小分片文件按预设聚合规则存储于聚合文件中，所述聚合文件存储于文件***；并将所述小分片文件在所述聚合文件中的描述信息存储于信息描述库中。
所述信息描述库既可存放于文件***中，也可存放于数据库中亦或存放于其他地方。
该录制任务从管理装置中获取，包括频道号和流媒体频道源站主索引文件地址信息等，通过频道号和流媒体源站主索引地址信息，获取该频道 下主索引文件，并对主索引文件进行解析，得到该频道下的码率信息和子索引文件下载地址信息；根据子索引文件下载地址信息，得到该频道该码率下的各子索引文件；对各子索引文件进行解析，得到该频道该码率下各小分片文件下载地址信息，最后依次访问各小分片文件下载地址信息，获取小分片文件。
进一步的，处理模块62包括：
选择子模块621，配置为选择所述小分片文件采用累积播放时长聚合规则、存入分片累积个数聚合规则和存入分片累积占用字节聚合规则中的哪一种聚合规则存储于聚合文件；
处理子模块622，配置为根据所述选择子模块621选择的聚合规则，对小分片文件进行存储。
上述的三种预设聚合规则均是将许多小分片文件聚合成一个大文件进行存储，这种聚合规则并不限定于上述三种，也可以通过其他方式进行聚合，聚合机制类似，对于其他聚合规则，也在本实施例保护的范围内，这里不再详细赘述。
进一步的，处理子模块622包括：
第一处理单元6221，配置为根据所述选择子模块621选择的累积播放时长聚合规则，将小分片文件依次按照字节偏移量存入聚合文件，当存入的小分片文件累计播放时长等于预设累积播放时长阈值时，将后续的小分片文件存入下一聚合文件中；
第二处理单元6222，配置为根据所述选择子模块621选择的存入分片累积个数聚合规则，将小分片文件依次按照字节偏移量存入聚合文件，当存入的小分片文件累积个数等于预设累积个数阈值时，将后续的小分片文件存入下一聚合文件中；
第三处理单元6223，配置为根据所述选择子模块621选择的存入分片 累积占用字节聚合规则，将小分片文件依次按照字节偏移量存入聚合文件，当存入的小分片文件累积占用字节等于预设累计占用字节阈值时，将后续的小分片文件存入下一聚合文件中。在本实施例中，优选地，采用第一处理单元6221对小分片文件进行存储。
此外，请参考图2，对于小分片文件按照字节偏移量依次存入聚合文件，其存储方式如下：假设第一个小分片文件的起始值为0，所有小分片文件的字节偏移量均为2，将第一个小分片文件存放于聚合文件中，再将第二小分片文件存入其中，该小分片文件起始值为2，依次类推，直到聚合文件达到***设定的存储阈值N。新建另一个聚合文件，继续将后续的小分片文件存入新建的聚合文件，该聚合文件中第一个小分片文件的起始值依然为0，按照之前聚合文件的存储方式，依次将各小分片文件存入新建的聚合文件中，直到该聚合文件达到***设定的存储阈值N。此外，小分片文件按照字节偏移量进行存储的方式不限于上述两种方式，也可通过其他方式实现小分片文件按字节偏移量存储的方式，对于其他存储方式，也在本实施例保护的范围内，这里不再详细赘述。
请参考图3，假设聚合文件的回看时长为4天，Day1存储了A个小分片文件，当前回看时长是5天，故需要老化删除Day1中的聚合文件，当录制装置录制的流媒体频道直播码流超过***设定期限时，就会将超过的部分老化删除，具体老化删除过程如下：
获取预设的有效期回看时长阈值，根据所述有效期回看时长阈值和所述各小分片文件的描述信息确定出在所述有效期回看时长阈值之前的老化小分片文件，并从所述文件***中删除与所述老化小分片文件对应的聚合文件；所述老化小分片文件为超过有效期回看时长阈值需要被删除的文件。
在对聚合文件进行老化删除时，存在聚合文件中的部分小分片文件需要被老化删除，如图3所述，F4聚合文件跨越了Day1和Day2，老化删除 时只需删除处于Day1部分的小分片文件，对应的描述信息也需要被老化删除。也就是说根据对应的各小分片文件描述信息中的起止时间判断哪些小分片文件需要被老化删除；对于聚合文件刚好整个被老化删除时，根据最后一个小分片文件播放结束时间判断哪些聚合文件需要被老化删除。
