Description

单分片视频播放加速方法及装置
技术领域
本发明涉及网络流媒体传输技术领域，尤其涉及一种单分片视频播放加速方法及装置。
背景技术
随着互联网技术的发展，网络视频点播逐渐成为当前最热门的互联网应用之一。目前网络上支持网络点播的网络播放器（即播放端）有多种，如爱奇艺、腾讯、乐视、芒果TV等，这些网络播放器通过与其对应的网络服务器（即服务器端）配合而完成视频点播。
在视频点播过程中，码流（即视频数据）的下载往往采用多任务下载方式进行处理，以达到加速下载、流畅播放视频的目的，其中该多任务下载是指将要下载的目标数据分段，然后用多个下载任务同时下载这些数据，最后将下载的数据拼凑成目标数据。对于视频点播，在服务器端，根据目标视频文件是否做切片，将目标视频文件分为单分片和多分片两种方式。
目前，只存在多分片目标视频文件的播放加速方案，即服务器端将目标视频文件切割成一个个的小块，每个小块为一个独立的分段，拥有自己的链接地址，一个目标视频的所有分段链接地址按顺序存储在一个m3u8格式的文件里。播放端在播放多分片目标视频文件时，先获取m3u8个数的文件并将所有的链接地址解析出来，然后启动多任务下载并缓存目标视频文件以供播放端调用播放，其中每个任务对应一个小块；而不存在关于单分片目标视频文件的播放加速方案。
发明内容
本发明的主要目的在于提供一种单分片视频播放加速方法及装置，旨在解决不存在关于单分片目标视频文件播放加速方案的技术问题。
为实现上述目的，本发明提供的一种单分片视频播放加速方法，单分片视频播放加速方法包括：
当截获到播放端发送至服务器端的用于请求播放目的单分片视频的视频播放请求时，判断该视频播放请求的合法性；
当判定该视频播放请求合法时，获取该视频播放请求中请求播放该目的单分片视频的第一请求时间点和请求播放数据分段的段数据长度；其中，该第一请求时间点为请求播放目的单分片视频的播放开始时间点；该段数据长度为播放端一次请求播放目的单分片视频的数据分段的数据长度；
从服务器端的目的单分片视频的第一请求时间点处开始下载视频数据，并将下载的视频数据转发至播放端实时播放；
当下载的视频数据的数据长度等于段数据长度时，同时下载并缓存目的单分片视频中第一请求时间点对应数据分段之后一个或多个数据分段以供播放端后续调用和播放；
实时记录缓存的数据分段的缓存进度；当检测到播放端请求播放的数据分段为缓存的数据分段时，获取该请求播放的数据分段的缓存进度，将该请求播放的数据分段作为缓存请求数据分段；
若缓存请求数据分段的缓存进度为就绪，则将该缓存请求数据分段转发至播放端以供其播放；若缓存请求数据分段的缓存进度为未就绪，则提示播放端等待该缓存请求数据分段下载完毕。
本发明还提供一种单分片视频播放加速方法，单分片视频播放加速方法包括：
当截获到播放端发送至服务器端的用于请求播放目的单分片视频的视频播放请求时，获取该视频播放请求中请求播放该目的单分片视频的第一请求时间点和请求播放数据分段的段数据长度；
从服务器的目的单分片视频的第一请求时间点处开始下载视频数据，并将下载的视频数据转发至播放端实时播放；
当下载的视频数据的数据长度等于段数据长度时，同时下载并缓存目的单分片视频中第一请求时间点对应数据分段之后一个或多个数据分段以供播放端后续调用和播放。
为实现上述目的，本发明还提供一种单分片视频播放加速装置，单分片视频播放加速装置包括：
获取模块，用于当截获到播放端发送至服务器端的用于请求播放目的单分片视频的视频播放请求时，获取该视频播放请求中请求播放该目的单分片视频的第一请求时间点和请求播放数据分段的段数据长度；

下载缓存模块，用于当下载的视频数据的数据长度等于段数据长度时，同时下载并缓存目的单分片视频中第一请求时间点对应数据分段之后一个或多个数据分段以供播放端后续调用和播放。
本发明在保证播放端流畅播放单分片视频数据的基础上，加速了单分片视频数据下载和缓存，尽可能保证播放端可以调用待播放的数据分段，从而实现了单分片视频播放的加速。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种单分片视频播放加速方法，在本发明单分片视频播放加速方法的第一实施例中，参照图1，该单分片视频播放加速方法包括：
步骤S10，当截获到播放端发送至服务器端的用于请求播放目的单分片视频的视频播放请求时，获取该视频播放请求中请求播放该目的单分片视频的第一请求时间点和请求播放数据分段的段数据长度；
当单分片视频播放加速装置（之后简称加速装置）截获到播放端（例如网络播放器）发送至服务器端（网络播放器对应的视频存储服务器）的视频播放请求时，获取该视频播放请求中的第一请求时间点和段数据长度，其中，该加速模块相对于服务器端和播放端是透明的，是设于服务器端和播放端之间的一种类似代理的独立模块；该视频播放请求用以请求播放目的单分片视频；该第一请求时间点为请求播放目的单分片视频的播放开始时间点；该段数据长度为播放端一次请求播放目的单分片视频的数据分段的数据长度。在本实施例中，目的单分片视频第一时间点附近的数据分段均未被下载和缓存。
当加速装置截获到播放端发送至服务器端的视频播放请求时，判断该视频播放请求的合法性，即判断发送该视频播放请求的播放端身份是否有效、判断该视频播放请求对应的目的单分片视频是否存在于对应服务器端中、通过跳跃性的请求分段测试该视频播放请求对应的目的单分片视频，判断该目的单分片视频整个分片是否正常等合法性判断，当判定该视频播放请求合法时，获取该视频播放请求中请求播放该目的单分片视频的第一请求时间点和请求播放数据分段的段数据长度。
步骤S20，从服务器端的目的单分片视频的第一请求时间点处开始下载视频数据，并将下载的视频数据转发至播放端实时播放；
当加速装置获取到目的单分片视频的第一请求时间点和段数据长度后，并不会立即将下载后的视频数据进行缓存，而是在一段时间内边下载视频数据边实时将已下载视频数据实时转发至播放端播放，即从服务器端的目的单分片视频的第一请求时间点处开始下载视频数据，并将下载的视频数据转发至播放端实时播放。例如，目的单分片视频为一个时长100s、数据长度20M的视频数据，第一请求时间点为0 s，段数据长度为2M，则加速装置从服务器中目的单分片视频的0 s处开始下载视频数据，并将下载好的视频数据实时转发至播放端实时播放，防止在网络视频点播一开始播放时出现卡顿，影响视频的流畅播放而影响用户体验。
步骤S30，当下载的视频数据的数据长度等于段数据长度时，同时下载并缓存目的单分片视频中第一请求时间点对应数据分段之后一个或多个数据分段以供播放端后续调用和播放。
当加速装置下载的视频数据的数据长度等于段数据长度时，可以判断加速装置下载的视频数据的数据长度是否大于播放端已经播放的视频数据的数据长度预设数据长度（例如0M或1M等），当加速装置下载的视频数据的数据长度大于播放端已经播放的视频数据的数据长度预设数据长度时，表明加速装置的下载带宽（即下载速度）大于播放端的播放码率（即播放速度），此时播放端流畅播放视频数据，可以启动播放加速，即同时下载并缓存目的单分片视频中第一请求时间点对应数据分段之后一个或多个数据分段以供播放端后续调用和播放。接上述步骤S20中的例子，当加速装置下载的视频数据的数据长度等于2M时，同时下载并缓存目的单分片视频2M之后的一个或多个2M数据分段，若缓存的数据分段为一个时，则下载并缓存目的单分片视频中2M至4M区间的数据分段以供播放端后续调用和播放；若缓存的数据分段为三个时，则同时下载并缓存目的单分片视频中2M至4M区间、4M至6M区间、6M至8M区间的数据分段以供播放端后续调用和播放。
在本实施例中，通过在截获到播放端发送的视频播放请求时，获取该视频播放请求中的第一请求时间点和段数据长度；然后从服务器端的目的单分片视频的第一请求时间点处开始下载视频数据，并将下载的视频数据转发至播放端实时播放；当下载的视频数据的数据长度等于段数据长度时，同时下载并缓存目的单分片视频中第一请求时间点对应数据分段之后一个或多个数据分段以供播放端后续调用和播放，从而避免在播放端刚开始播放接收的视频数据时，因同时下载并缓存多个数据分段而导致正在播放的数据分段下载慢、播放卡顿，在下载的视频数据的数据长度等于段数据长度时，即数据分段间开始连续，播放端播放可以流畅时，同时下载并缓存目的单分片视频中第一请求时间点对应数据分段之后一个或多个数据分段，以尽可能多的缓存视频数据，从而在保证播放端流畅播放单分片视频数据的基础上，加速了单分片视频数据下载和缓存，尽可能保证播放端可以调用待播放的数据分段，从而实现了单分片视频播放的加速。
进一步地，在本发明单分片视频播放加速方法第一实施例的基础上，提出单分片视频播放加速方法第二实施例，步骤S30之后还包括：
步骤S40，实时记录缓存的数据分段的缓存进度；
在对目的单分片视频的数据分段进行缓存时，实时记录各个进行缓存的数据分段的缓存进度，缓存进度可以包括就绪和未就绪两种状态，当某个数据分段下载并缓存完毕时，其缓存进度为就绪；当某个数据分段没有下载并缓存完毕时，其缓存进度为未就绪。
步骤S50，当检测到播放端请求播放的数据分段为缓存的数据分段时，获取该请求播放的数据分段的缓存进度，将该请求播放的数据分段作为缓存请求数据分段；
当加速装置再次截获到播放端发送的关于目的单分片视频的再次视频播放请求时，检测接收的再次视频播放请求若检测到该再次视频播放请求所请求播放的数据分段为缓存的数据分段时，获取该再次视频播放请求所请求播放的数据分段的缓存进度，并将该再次视频播放请求所请求播放的数据分段作为缓存请求数据分段。获取缓存请求数据分段的缓存进度。
步骤S501，判断缓存请求数据分段的缓存进度是否为就绪；
步骤S51，若缓存请求数据分段的缓存进度为就绪，则将该缓存请求数据分段转发至播放端以供其播放；
步骤S52，若缓存请求数据分段的缓存进度为未就绪，则提示播放端等待该缓存请求数据分段下载完毕。
加速装置获取缓存请求数据分段的缓存进度，若该缓存请求数据分段的缓存进度为就绪，表明加速装置已经将该缓存请求数据分段从服务器端下载并缓存完毕了，直接从缓存中将该缓存请求数据分段转发至播放端播放；若该缓存请求数据分段的缓存进度为未就绪，表明加速装置还未将该缓存请求数据分段从服务器端下载并缓存完毕，无法从缓存中取出该缓存请求数据分段，向播放端发送提示指令，提示播放端等待该缓存请求数据分段下载完毕，也可以通过提示指令控制播放端停止播放以等待该缓存请求数据分段下载完毕，下载该缓存请求数据分段所需时间可以同步显示于播放端。
在本实施例中，在同时下载并缓存目的单分片视频中第一时间点后一个或多个数据分段后，实时记录各个缓存的数据分段的缓存进度，当检测到播放端请求播放缓存请求数据分段时，获取该缓存请求数据分段的缓存进度，若缓存请求数据分段的缓存进度为就绪，则将该缓存请求数据分段转发至播放端以供其播放；若缓存请求数据分段的缓存进度为未就绪，则提示播放端等待该缓存请求数据分段下载完毕；从而在网络状态较佳时，直接将缓存请求数据分段转发至播放端，在网络状态不佳时，提示播放端等待以加速缓存更多数据后再播放，避免经常性的播放卡顿。
进一步地，在本发明单分片视频播放加速方法第二实施例的基础上，提出单分片视频播放加速方法第三实施例，步骤S52之后，该单分片视频播放加速方法还包括：
步骤S53，当播放端等待缓存请求数据分段下载的时长大于预设等待时长时，全速下载和缓存该缓存请求数据分段，直至该缓存请求数据分段的缓存进度为就绪。
在检测到播放端请求播放缓存请求数据分段时，获取该缓存请求数据分段的缓存进度，当判定缓存请求数据分段的缓存进度为未就绪时，加速装置提示播放端等待该缓存请求数据分段下载完毕；当检测到播放端等待该缓存请求数据分段下载的时长大于预设等待时长时，即表明播放端等待缓存请求数据分段下载等待时间过长，网速可能欠佳，此时不宜继续多个数据分段一起下载，暂停下载该请求播放的缓存请求数据分段之外的数据分段，全速下载和缓存该缓存请求数据分段，直至该缓存请求数据分段的缓存进度为就绪。
例如，目的单分片视频为一个时长100s、数据长度20M的视频数据，第一请求时间点为0 s，段数据长度为2M，当0M至2M的数据分段下载完毕后，同时下载并缓存目的单分片视频中2M至4M区间、4M至6M区间、6M至8M区间的数据分段，播放端请求播放的数据段为4M至6M区间的数据分段；但是4M至6M区间的数据分段的缓存进度为未就绪，加速装置提示播放端等待该4M至6M区间的数据分段下载完毕；当检测到播放端等待该缓存请求数据分段下载的时长大于预设等待时长时，暂停下载2M至4M区间、6M至8M区间的数据分段，全速下载4M至6M区间的数据分段，当4M至6M区间的数据分段的缓存进度为就绪时，重新开始下载2M至4M区间、6M至8M区间的数据分段。
在本实施例中，通过在播放端等待缓存请求数据分段下载的时长大于预设等待时长时，全速下载和缓存该缓存请求数据分段，直至该缓存请求数据分段的缓存进度为就绪，避免播放端等待过长时间，灵活地调整各个数据分段的下载状态，避免播放端播放视频出现长时间卡顿。
进一步地，在本发明单分片视频播放加速方法第一实施例的基础上，提出单分片视频播放加速方法第四实施例，在第四实施例中，步骤S30之后还包括：
步骤S60，当检测到播放端请求播放的数据分段不是缓存的数据分段时，获取该请求播放的数据分段的第二请求时间点，并释放已缓存的数据分段；
当下载的视频数据的数据长度等于段数据长度时，加速装置同时下载并缓存目的单分片视频中第一请求时间点对应数据分段之后一个多个数据分段，若此时再次检测到播放端发送的视频播放请求，且在该视频播放请求所请求播放的数据分段不是之前缓存的数据分段时，即播放端请求播放目的单分片视频中未下载也未缓存的数据分段时，获取该请求播放的数据分段的起始时间点（即第二时间点），并释放之前已缓存的数据分段。例如目的单分片视频为一个时长100s、数据长度20M的视频数据，第一请求时间点为0 s，段数据长度为2M，已缓存的数据分段有2M至4M区间、4M至6M区间、6M至8M区间的数据分段，此时播放端请求播放12M至14M区间的数据分段，则获取12M至14M区间的数据分段的起始时间点，并释放已缓存的2M至4M区间、4M至6M区间、6M至8M区间的数据分段。
步骤S70，从服务器端的目的单分片视频的第二请求时间点处开始下载视频数据，并将下载的视频数据转发至播放端实时播放；
步骤S80，当下载的视频数据的数据长度等于段数据长度时，同时下载并缓存目的单分片视频中第二请求时间点对应数据分段之后一个或多个数据分段以供播放端后续调用和播放。
接上述步骤S60中的例子，从服务器端的目的单分片视频中12M至14M区间的数据分段的起始时间点（即第二请求时间点）处开始下载视频数据，并将从12M至14M区间的数据分段下载的视频数据转发至播放端实时播放。当从12M至14M区间数据分段下载的视频数据的数据长度等于段数据长度时，同时下载并缓存12M至14M区间数据分段之后的一个或多个数据分段，如同时下载并缓存14M至16M区间、16M至18M区间、18M至20M区间的数据分段。
在本实施例中，当检测到播放端请求播放的数据分段不是缓存的数据分段时，全速下载播放端新请求播放的数据分段，并将下载的视频数据转发至播放端实时播放，同时，释放之前缓存的数据分段，暂停其它所有数据分段的下载；当下载新请求播放的数据分段的数据长度等于段数据长度时，即新请求播放的数据分段下载完毕时，同时下载并缓存目的单分片视频中第二请求时间点对应数据分段之后一个或多个数据分段，即同时下载并缓存目的单分片视频中新请求播放的数据分段之后一个或多个数据分段以供播放端后续调用和播放，
进一步地，在本发明单分片视频播放加速方法第一实施例的基础上，提出单分片视频播放加速方法第五实施例，在第五实施例中，步骤S30包括：
步骤S31，获取从服务器端下载视频数据的下载速度和播放端播放视频数据的播放速度；
加速装置获取其从服务器端下载视频数据的下载速度（即下载带宽，单位时间内下载的数据位数）和播放端播放视频数据的播放速度（即播放码率，单位时间内播放的数据位数），例如下载速度为4Mbps，播放速度为2Mbps。
步骤S32，比较下载速度和播放速度；
步骤S33，若下载速度大于播放速度，则当下载的视频数据的数据长度等于段数据长度时，同时下载并缓存目的单分片视频中请求播放数据分段之后指定数目数据分段以供播放端后续调用和播放，该指定数目是根据段数据长度、下载速度和播放速度得出。
比较下载速度和播放速度，若下载速度小于等于播放速度，则当下载的视频数据的数据长度等于段数据长度时，继续下载目的单分片视频中请求播放数据分段之后的数据分度，并将下载的视频数据转发至播放端实时播放，即继续边下载边实时转发已下载；若下载速度大于播放速度，则当下载的视频数据的数据长度等于段数据长度时，同时下载并缓存目的单分片视频中请求播放数据分段之后指定数目数据分段以供播放端后续调用和播放，该指定数目是根据段数据长度、下载速度和播放速度得出。例如下载速度8Mbps，播放速度为2Mbps，段数据长度为2M，则下载一个段数据长度的数据分段需0.25s，播放一个数据分段需1s，则在下载完一个数据分段至播放端播放完一个数据分段的时间间隔为0.75s，这这0.75s内能够下载6M视频数据，该6M视频数据正好为3个数据分段的数据长度，预设数目为3。
在本实施例中，通过获取并比较下载速度和播放速度，若下载速度大于播放速度，则当下载的视频数据的数据长度等于段数据长度时，同时下载并缓存目的单分片视频中请求播放数据分段之后指定数目数据分段以供播放端后续调用和播放，该指定数目是根据段数据长度、下载速度和播放速度得出,从而避免下载速度小于等于播放速度时，进行数据分段缓存而造成播放端播放视频出现卡顿；也避免下载和缓存的数据分段的数目过大，造成缓存数据分段下载时间过长，避免导致播放端调用未下载完毕的数据分段而造成播放端播放卡顿；以及避免下载和缓存的数据分段的数目过小，造成下载带宽的浪费。
此外，在本发明单分片视频播放加速方法第二、第三实施例的基础上，步骤S30包括：
步骤S31，获取从服务器端下载视频数据的下载速度和播放端播放视频数据的播放速度；
加速装置获取其从服务器端下载视频数据的下载速度（即下载带宽，单位时间内下载的数据位数）和播放端播放视频数据的播放速度（即播放码率，单位时间内播放的数据位数），例如下载速度为4Mbps，播放速度为2Mbps。
步骤S32，比较下载速度和播放速度；
步骤S33，若下载速度大于播放速度，则当下载的视频数据的数据长度等于段数据长度时，同时下载并缓存目的单分片视频中请求播放数据分段之后指定数目数据分段以供播放端后续调用和播放，该指定数目是根据段数据长度、下载速度和播放速度得出。
