Description
本申请要求在2022年03月23日提交中国专利局，申请号为202210293767.2的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
本申请实施例涉及视频处理技术领域，尤其涉及一种视频流中预加载直播间方法、装置、设备及存储介质。
随着短视频应用的普及发展，经常会在数据消费流中混合视频和直播内容，丰富用户的体验场景，短视频的预下载业务存在不少解决方案，如用户在上下滑动消费短视频的过程中，预下载不可见的上下多个视频文件，准备好本地文件资源，用户滑动消费时可快速播放视频，而当短视频切换至直播时，由于业务形态差异大，短视频为文件播放，直播为实时的数据流播放，无法使用类似的预加载方案。
相关技术中通常是短视频切换直播时，整个页面切换为直播数据时开始加载直播资源，进入直播间并开始拉数据流，渲染直播页面数据，但直播间是比较复杂的业务场景，秒出率不高，而且短视频播放和直播播放均需要占用一定的网络带宽，如果贸然在短视频播放时预加载直播间，一方面可能影响短视频的消费体验，导致短视频卡顿，短视频预加载和短视频秒出率也会有劣化。而且终端碎片化严重，即用户观看短视频和直播的设备各异，从而加大短视频播放时预加载直播间的难度。

本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
图1为本申请实施例提供的一种视频流中预加载直播间方法的流程图，用于在视频流数据播放过程中对直播间资源进行预加载，该方法可以由计算设备如智能终端、笔记本等来执行，具体包括如下步骤：
步骤S110、在视频流数据播放过程中，检测到满足预加载触发场景时，获取当前的设备环境信息和业务环境信息。
在一个实施例中，在视频流数据播放过程中，即在用户设备播放短视频的过程，预加载触发场景被检测到，从而获取当前的设备环境信息和业务环境信息。可选的，预加载触发场景可以配置为通过上滑操作切换播放内容时，当前播放数据为短视频，下一播放数据为直播视频，可以理解的是，上滑操作为实现切换播放内容的切换方式，即用户可以通过上滑操作来切换播放内容，如将当前正在播放、未播放或暂停的短视频切换为下一个短视频或者直播视频，而对于用户设备如智能终端，在接收到对应于上滑操作的滑动操作数据后，若当前播放视频为短视频，切换后的播放数据为直播视频，则满足触发条件。需要说明的是，当前播放数据为短视频可以理解为当前的数据类型是视频流数据，并不代表该短视频处于播放状态，即该短视频可以是正在播放、未播放或暂停三种状态中的一种。
在另一个实施例中，预加载触发场景可以配置为通过下滑操作切换播放内容时，当前播放数据为短视频，上一播放数据为直播视频，可以理解的是，下滑操作为实现切换播放内容的切换方式，即用户可以通过下滑操作来切换播放内容，如将当前正在播放、未播放或暂停的短视频切换为上一个短视频或者直播视频，而对于用户设备如智能终端，在接收到对应于下滑操作的滑动操作数据后，若当前播放数据为短视频，切换后的播放数据为直播视频，则满足触发条件。
需要说明的是，对于本申请实施例提供的方法还可以控制用户设备响应于用户的左滑或右滑操作切换播放内容，且当前播放数据为短视频，上一播放数据或下一播放数据为直播视频，判断满足预加载触发场景。
在一个实施例中，设备环境信息包括网络类型、网络带宽和短视频下载带宽中的一种或多种，其中，网络类型为用户设备当前使用的网络所示的类型，对于智能终端如手机，则其网络类型可以是2G、3G、4G、5G或WiFi中的一种，对于计算机如台式电脑，则其网络类型可以是宽带或网关等，网络带宽为用户设备当前使用的网络的带宽，而短视频下载带宽为下载短视频时占用的带宽，需要说明的是，短视频下载带宽还可以用下载短视频时所占用的带宽在网络带宽中的占比来表示。
在一个实施例中，业务环境信息包括短视频下载数据和/或短视频缓存数据，
可以理解的是，短视频下载数据用于确定短视频是否完成下载，对于短视频缓存数据可以包括已缓存且已播放的时间和/或已缓存但未播放的时间，短视频缓存数据还可以包括已缓存且已播放的时长占比和/或已缓存但未播放的时长占比，其中，已缓存且已播放的时长占比表示已播放时长与缓存内容时长之比，已缓存但未播放的时长占比表示未播放时长与缓存内容时长之比。
步骤S120、确定设备环境信息是否满足预加载设备条件，以及确定业务环境信息是否满足预加载业务条件。
在一个实施例中，预加载设备条件可以是确定网络类型是否为预设网络类型；或者，确定网络带宽是否大于预设网络带宽阈值；或者，确定短视频下载带宽是否大于预设下载带宽阈值。其中，预加载设备条件可以依据上述条件设置其中的至少一种，预加载设备条件可以由用户设备从云端或服务器上获取，或者用户设备向云端或服务器发送相应的请求，由云端或服务器发送预加载设备条件。
对于确定网络类型是否为预设网络类型，其中，对于智能终端如手机，则预设网络类型可以是2G、3G、4G、5G或WiFi中的一种或多种，对于计算机如台式电脑，则网络类型可以是宽带或网关等。示例性的，预设网络类型可以设置为4G、5G或WiFi，而用户设备当前的网络类型为4G，则确定网络类型为预设网络类型，满足预加载设备条件；而用户设备当前的网络类型为3G，则用户设备的网络类型不是预设网络类型，且不满足预加载设备条件。
对于确定网络带宽是否大于预设网络带宽阈值，示例性的，预设网络带宽阈值可以设置为2M bps，则用户设备的网络带宽为3M bps，满足网络带宽大于预设网络带宽阈值，而用户设备的网络带宽为1M bps，则用户设备的网络带宽小于预设网络带宽阈值，且不满足预加载设备条件。
对于确定短视频下载带宽是否大于预设下载带宽阈值，示例性的，短视频下载带宽为下载短视频时占用的带宽，则预设下载带宽阈值设置为150KB/s，而用户设备当前的短视频下载带宽为200KB/s，确定短视频下载带宽大于预设下载带宽阈值；而用户设备当前的短视频下载带宽为100KB/s，则短视频下载带宽小于预设下载带宽阈值，且不满足预加载设备条件。
需要说明的是，预设网络类型、预设网络带宽阈值和预设下载带宽阈值可
以根据实际设计需要进行设置。当预加载设备条件包括多个设定，则需要全部满足，才能够确定设备环境信息满足预加载设备条件。
在一个实施例中，预加载业务条件包括：根据短视频下载数据确定短视频是否下载完毕；和/或，根据短视频缓存数据确定已缓存但未播放的时间是否大于预设时间。
示例性的，短视频下载数据可以是在短视频下载成功后生成一个用于表示下载成功的信息，计算设备接收到该信息，则确定短视频下载完毕。
短视频缓存数据包括已缓存但未播放的时间，对比已缓存但未播放时间和预设时间，示例性的，如短视频已下载5000ms，当前播放时间为2000ms，则短视频已下载未播放的时长为3000ms，若预设时间为2500ms，则满足已缓存但未播放时间大于预设时间。短视频缓存数据还可以是用已缓存但未播放时间在已缓存时间的时长占比，即根据短视频缓存数据确定已缓存但未播放的时长是否大于预设占比，来确定业务环境信息是否满足预加载业务条件。
需要说明的是，预设时间可以根据实际设计需要进行设置。在预加载业务条件包括上述两个设定的情况下，当短视频已经下载完成，则忽略短视频缓存数据，即不需要根据短视频缓存数据确定已缓存但未播放的时间是否大于预设时间。
步骤S130、响应于满足预加载设备条件以及预加载业务条件的判断结果，进行直播间资源的预加载。
在一个实施例中，在确定设备环境条件满足预加载设备条件以及确定业务环境条件满足预加载业务条件后，计算设备进行响应，对直播间资源进行预加载，如获取直播间资源，进入对应的直播间，可以想到的是，对于需要进行预加载的直播间，用户设备获取直播间资源，如直播视频的编码方式、画面分辨率、界面布局数据以及直播流数据等，做进入直播间的准备。
由上述方案可知，在用户设备播放视频流数据的过程中，对用户设备是否满足预加载触发场景进行检测，当用户设备满足预触发场景，且设备环境信息和业务环境信息均满足预加载设备条件和预加载业务条件，则预加载直播间资源，从而能够在不影响短视频的消费体验的前提下，同时还能够预加载直播间，使得短视频和直播数据之间的切换自然流畅，提升用户对短视频和直播间的消
费体验。
在一个实施例中，在视频流数据播放过程中，检测到满足预加载触发场景时，且在满足预加载触发时机时，获取当前的设备环境信息和业务环境信息。其中，预加载触发时机包括短视频播放至预设时间点或预设时间点后的预设时间间隔点，可以理解的是，满足预加载触发时机的时间点包括预设时间点及其后的多个预设时间间隔点即满足预设时间间隔的时间点，示例性的，预设时间点设置为1000ms，预设时间间隔点为从预设时间点起每隔500ms的时间点，如1500ms、2000ms等，即表示在预设时间点1000ms以及从1000ms起每隔500ms对应的时间点确定为满足预加载时机，获取当前的设备环境信息和业务环境信息进行判断，确定是否满足预加载条件，直到满足预加载条件且直播间资源预加载成功为止。
由此可见，当用户设备满足预触发场景，还满足预加载触发时机，且设备环境信息和业务环境信息均满足预加载设备条件和预加载业务条件，则预加载直播间资源，在满足预加载触发时机这一条件下，间隔地触发预加载，从而能够在不影响短视频的消费体验的前提下，同时还能够预加载直播间，使得短视频和直播数据之间的切换更加自然流畅，提升了用户对短视频和直播间的消费体验。
图2是本申请实施例提供的另一种视频流中预加载直播间方法的流程图，具体包括如下步骤：
步骤S210、在视频流数据播放过程中，检测到满足预加载触发场景时，获取当前的设备环境信息和业务环境信息。
步骤S220、确定设备环境信息是否满足预加载设备条件，以及确定业务环境信息是否满足预加载业务条件。
步骤S230响应于满足预加载设备条件以及预加载业务条件的判断结果，获取服务器发送的预加载策略，进行直播间资源的预加载。
在一实施例中，对直播间资源进行预加载之前，还需要获取服务器发送的预加载策略，预加载策略为服务器根据获取的设备基础信息确定，设备基础信息包括设备的处理器核数、处理器频率以及运行内存中的至少一种。
示例性的，设备基础信息中包括处理器核数、处理器频率以及运行内存，
服务器能够根据上述的设备基础信息确定用户设备的机型等级，从而为用户设备提供对应的预加载策略，可以想到的是，服务器对应于用户设备的机型等级存储有相应的预加载策略，例如，对于机型等级为低端机型的用户设备，服务器发送第一预加载策略，如在获取直播间资源并进入对应直播间后，通过将直播间对应的播放音量设置为预设音量，再通过单像素点方式对直播间的直播画面进行绘制。
由上述方案可知，在用户设备播放视频流数据的过程中，对用户设备是否满足预加载触发场景进行检测，当用户设备满足预触发场景，且设备环境信息和业务环境信息均满足预加载设备条件和预加载业务条件，还获取服务器根据设备基础信息确定的预加载策略，从而预加载直播间资源，从而能够在不影响短视频的消费体验的前提下，同时适应不同机型等级的用户设备进行预加载直播间，使得短视频和直播数据之间的切换自然流畅，提升了用户对短视频和直播间的消费体验。
图3为本申请实施例提供的另一种视频流中预加载直播间方法的流程图，具体包括如下步骤：
步骤S310、在视频流数据播放过程中，检测到满足预加载触发场景时，获取当前的设备环境信息和业务环境信息。
步骤S320、确定设备环境信息是否满足预加载设备条件，以及确定业务环境信息是否满足预加载业务条件。
步骤S330、响应于满足预加载设备条件以及预加载业务条件的判断结果，获取直播间资源，进入对应的直播间。
步骤S340、对直播间进行声音屏蔽和视频流播放屏蔽。
在一实施例中，对于进行直播间资源的预加载包括获取直播间资源，进入对应的直播间；对直播间进行声音屏蔽和视频流屏蔽。其中，对于需要进行预加载的直播间，用户设备获取直播间资源，如直播视频的编码方式、画面分辨率、界面布局数据以及直播流数据等；进入对应的直播间，并对直播间的声音和画面进行屏蔽，从而减低对当前播放的短视频的影响，提升了用户的使用体验。
在一个实施例中，在进行直播间资源的预加载的过程中，获取直播间资源，
进入对应直播间后，可以通过将直播间对应的播放音量设置为预设音量，再通过单像素点方式对直播间的直播画面进行绘制，以实现对直播间进行声音屏蔽和视频流播放屏蔽。可以理解的是，预设音量是预设置的播放音量，可以根据需要设置，示例性的，可以在进行预加载的过程中，对直播间的播放音量设置为0，即在预加载直播间资源的过程中不播放直播间的声音。对直播间进行声音屏蔽还可以是禁用视频流数据中的音频数据，而在进行直播视频播放时，再恢复音频数据。对于直播间的画面，还可以采用多个像素点进行绘制；直播间的画面还可在用户设备的系统后台绘制，实现对直播间进行视频流播放屏蔽。
由上述方案可知，在用户设备播放视频流数据的过程中，当用户设备满足预触发场景，且设备环境信息和业务环境信息均满足预加载设备条件和预加载业务条件，从而预加载直播间资源，并对直播的声音和画面进行屏蔽，能够实现在不影响短视频的消费体验的前提下，预加载直播间，使得短视频和直播数据之间的切换自然流畅，提升了用户对短视频和直播间的消费体验。
图4为本申请实施例提供的另一视频流中预加载直播间方法的流程图，具体步骤包括：
步骤S410、在视频流数据播放过程中，检测到满足预加载触发场景时，获取当前的设备环境信息和业务环境信息。
步骤S420、确定设备环境信息是否满足预加载设备条件，以及确定业务环境信息是否满足预加载业务条件。
步骤S430、响应于满足预加载设备条件以及预加载业务条件的判断结果，获取直播间资源，进入对应的直播间。
步骤S440、对直播间进行声音屏蔽和视频流播放屏蔽。
步骤S450、检测到当前播放内容切换至直播视频时，恢复直播间的声音和视频流播放。
在一实施例中，对于用户将短视频切换至直播视频，用户设备检测到当前播放内容切换至直播视频，恢复直播间的声音和视频流播放，即解除对直播间进行的声音屏蔽和视频流播放屏蔽，使得直播视频的声音和画面在用户设备上展示。
示例性的，在一应用场景中，用户设备当前正在播放短视频，且满足预加
载触发场景，用户设备当前的设备环境信息满足预加载设备提条件和业务环境信息满足预加载业务条件，即用户设备对直播间资源进行预加载，直播间的声音和画面均屏蔽。在用户设备检测到当前播放内容切换为直播视频，即由短视频切换至直播时，恢复直播间的声音和视频流播放，即关闭短视频的声音和画面，同时使直播间的声音恢复至默认音量如恢复至用户设备当前的音量，即播放短视频时的音量，且恢复直播间画面，正常展示直播。
图5为本申请实施例提供的另一视频流中预加载直播间方法的流程图，具体步骤包括：
步骤S510、在视频流数据播放过程中，检测到满足预加载触发场景时，获取当前的设备环境信息和业务环境信息。
步骤S520、确定设备环境信息是否满足预加载设备条件，以及确定业务环境信息是否满足预加载业务条件。
步骤S530、响应于满足预加载设备条件以及预加载业务条件的判断结果，获取直播间资源，进入对应的直播间。
步骤S540、对直播间进行声音屏蔽和视频流播放屏蔽。
步骤S550、检测到满足直播间资源释放条件时，退出直播间并释放直播间资源。
在一实施例中，在对直播间资源进行预加载后，还对直播间资源释放条件进行检测，当检测到满足直播间资源释放条件时，退出直播间并释放直播间资源，其中，直播间资源释放条件包括预设操作条件、网络变化条件、后台操作条件以及二级页面切换条件中的至少一种。
可以理解的是，预设操作条件包括确定当前操作指令是否为反向指令，反向指令是用户设备在预加载触发场景下且响应于用户使播放内容由短视频切换为另一短视频的反向滑动操作而接收到的操作指令，示例性的，在一视频流数据播放次序中，当前播放的视频流数据为短视频I，上一播放的视频流数据为短视频II，下一播放的视频流数据为直播，响应于用户的反向滑动操作，用户设备由播放短视频I改为播放短视频II，满足预设操作条件，则退出直播间并释放直播间资源。
网络变化条件包括确定变化后的网络类型是否满足超出预设网络类型，示
例性的，预设网络类型设置为4G、5G或WiFi，而用户设备变化后的网络类型为3G，则确定变化后的网络类型不为预设网络类型，即超出预设网络类型，满足网络变化条件，则用户设备退出直播间并释放直播间资源。
后台操作条件包括确定视频流数据是否处于系统后台，示例性的，在一视频应用上可以播放视频流数据，即播放短视频和直播，当用户将该视频应用退入用户设备的系统后台，满足后台操作条件，则退出直播间并释放直播间资源。
二级页面切换条件包括确定当前页面是否切换为二级页面，示例性的，在一视频应用中，用户可以进入二级页面如评论区页面、视频发布者页面等除当前播放视频流数据页面外的页面，当用户设备确定当前页面为二级页面，满足二级页面切换条件，则退出直播间并释放直播间资源。
