具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
相关技术中，对于不同类型、尺寸的终端设备，在播放直播视频时，只能以竖屏的方式播放，即使终端设备横屏放置，由于直播视频流无法随着终端设备的旋转而旋转，因此，终端设备仍然只能以竖屏的方式播放直播视频，造成了终端设备的使用局限性，影响用户的使用便捷性和使用体验。
下面对本公开实施例的应用场景进行解释：
图1为本公开实施例提供的直播视频流播放方法的一种应用场景图，本公开实施例提供直播视频流播放方法，可以应用在视频直播的应用场景下，具体地，如图1所示，例如，实施例提供直播视频流播放方法的执行主体可以为观众用户的第一终端设备11，该第一终端设备11与直播平台的云服务器12通信，接收云服务器12发送的视频流，并实时的进行解码，以及通过显示屏显示对应的视频图像，实现播放直播视频的过程。在与云服务器12连接的另一侧，为主播用户的第二终端设备13，第二终端设备13通过采集直播视频并推流至云服务器12，使观众用户在通过第一终端设备11访问其所在的直播间时，能够通过云服务器12接收到第二终端设备13推流的直播视频流，从而观看该直播间的直播视频。其中，第一终端设备 11内运行有直播应用，上述接收云服务器12发送的视频流并进行解码播放的过程，可以通过该直播APP实现，具体的过程此次不再赘述。
相关技术中，在视频直播这一特殊的应用场景下，对于不同类型、尺寸的终端设备，在播放直播视频时，即使终端设备横屏放置，由于直播视频流无法随着终端设备的旋转而旋转，因此，终端设备仍然只能以竖屏的方式播放直播视频，图2为相关技术中终端设备在不同旋转角度播放直播视频流的示意图，如图2所示，终端设备例如为平板电脑(Pad)，在平板电脑竖向放置时，直播视频流沿平板电脑的竖向播放，然而在平板电脑横向放置时，直播视频流仍然沿平板电脑的竖向播放，此次，就造成了用户观看平板电脑的不便，致使用户无法通过横向使用平板电脑的方式，观看视频直播，影响用户的使用便捷性。
而相关技术中终端设备仍然只能以竖屏的方式播放直播视频的原因，是由于不同的直播间推送的视频流的视频尺寸不一致，终端设备对视频流进行播放时，根据终端设备的显示屏尺寸，通常会对不同视频尺寸的视频流进行对应程度的缩放匹配，以实现匹配显示屏尺寸的最佳显示效果；而当终端设备旋转时，显示屏的横竖关系变化，也会导致视频流的缩放比例发生变化，从而导致终端设备无法确定视频流准确的播放尺寸，因此，相关技术中，是以固定的竖屏的方式播放直播视频流，而无法根据终端设备的旋转角度自动调整视频流的播放尺寸。
为解决上述技术问题，本公开实施例提供一种直播视频流播放方法、装置、电子设备及存储介质。
图3为本公开实施例提供的直播视频流播放方法的流程示意图一。如图3所示，本实施例的方法可以应用在具有显示屏的终端设备中，例如智能手机、平板电脑。该直播视频流播放方法包括：
步骤S101：接收目标直播间的视频流，并确定视频流的视频尺寸。
示例性地，终端设备内运行有直播客户端，即直播APP，在确定目标直播间后，接收服务器发送的与该目标直播间对应的视频流，其中，该视频流是由目标直播间所对应的直播终端基于流式传输方式推送的视频数据。视频流通过云服务器，由主播侧终端设备传输至观众侧终端设备的具体实现方式，为本领域技术人员知晓的相关技术，此处不对此过程进行赘述。
进一步的，终端设备在获取视频流后，对视频流进行解析，可以确定视频流的视频尺寸。示例性地，视频尺寸可以是指视频流的分辨率，视频尺寸是由拍摄该视频流对应的待播放视频的设备确定的，图4为本公开实施例提供的不同视频尺寸的视频流的示意图，如图4所示，例如，视频流A对应的视频，是由智能手机拍摄的，其视频尺寸为900*1600，长宽比为9:16。视频流B对应的视频，是通过电脑录屏产生的，其视频尺寸为1200*900，长宽比为4:3。
步骤S102：检测终端设备的旋转方向。
示例性地，终端设备的旋转方向，即为终端设备的空间状态，旋转方向包括第一方向和第二方向，其中，第一方向表征终端设备处于横屏状态，第二方向表征终端设备处竖屏方向。图5为本公开实施例提供的一种终端设备的旋转方向的示意图，如图5所示，终端设备具有矩形显示屏，显示屏包括长边和短边，其中，示例性地，长边在X-Z平面的投影，与Y-Z平面的夹角，即为旋转角度(图中示为θ)，当旋转角度处于第一预设区间内时，旋转方法为第一方向，即终端设备处于横屏状态；当旋转角度处于第二预设区间内时，旋转方法为第二方向，即终端设备处于竖屏状态。
在一种可能的实现方式中，终端设备的旋转方向可以通过终端设备内设置的重力检测单元进行检测。更具体地，通过获取终端设备的重力检测单元采集的重力感应信息，并根据重力感应信息，确定旋转方向。其中，重力检测单元例如为三维陀螺仪。
步骤S103：根据视频流的视频尺寸和旋转方向，确定视频流在显示屏上的播放尺寸，并以播放尺寸播放视频流。
示例性地，在确定视频流的视频尺寸后，根据终端设备的旋转方向，可以确定一个能够与屏幕尺寸和旋转方向相匹配的尺寸，即播放尺寸，通过该播放尺寸对视频流进行播放，实现最佳的视频展示效果。其中，示例性地，播放尺寸可以是在不对视频流进行单向拉伸，不改变视频流的视图比例的前提下，显示屏能够容纳的最大对角线尺寸，或者是小于该最大对角线尺寸的任意尺寸，例如最大对角线尺寸的0.8倍。
在确定播放尺寸后，以该播放尺寸对视频流进行播放，将视频流对应的直播视频显示在显示屏上，实现显示直播内容的目的。其中，当播放尺寸是显示屏能够容纳的最大对角线尺寸时，相当于全屏播放效果，能够提供更好的视频沉浸感；而当播放尺寸是小于显示屏能够容纳的最大对角线尺寸的某一尺寸时，可以在播放尺寸对应的视频流播放区域外，显示其他信息，例如视频流相关的文字信息，以适应不同直播应用场景的具体需求。
在本实施例中，通过接收目标直播间的视频流，并确定视频流的视频尺寸，检测终端设备的旋转方向，根据视频流的视频尺寸和旋转方向，确定视频流在显示屏上的播放尺寸，并以播放尺寸播放视频流。由于用于播放视频流的播放尺寸，是根据终端设备的旋转方向和视频流的视频尺寸所共同确定的，因此播放尺寸能够与终端设备的旋转方向和视频流的视频尺寸相匹配，进而，使终端设备能够在不同的旋转方向时，均能以合适的播放尺寸对视频流进行播放，提高视频流的显示效果，提高用户的观看体验。
图6为本公开实施例提供的直播视频流播放方法的流程示意图二。本实施例中对步骤S102进一步细化，并增加了切换目标直播间的步骤，该直播视频流播放方法包括：
步骤S201：接收目标直播间的视频流，并确定视频流的视频尺寸。
示例性地，视频尺寸包括视频流对应的待播放视频的视频长宽比。视频长宽比例如为4:3、16:9等。通过视频长宽比，可以确定视频流所对应的视频的图像长宽比例。通常情况下，该视频长宽比是在生成视频流时即确定的，并能够通过解析该视频流和获得表征视频长宽比的具体数值，此处不再对此过程赘述。
步骤S202：检测终端设备的重力检测单元是否开启，若未开启重力检测单元，则发出提示信息。
示例性地，在终端设备调用重力检测单元的相关功能前，首先检测该重力检测单元是否开启，具体地，例如，在终端设备的操作系统内设置有开启和关闭该重力检测单元的选项，通过设备通过检测操作系统中的相关设置，确定该选项是否被打开，从而确定重力检测单元是否被开启。进而，在重力检测单元未开启时，通过在直播APP内弹出提示信息的方式，提示用户开启重力检测单元，以实现对终端设备旋转方向的检测。其中，提示信息的具体内容，可以根据需要设置，此次不具体赘述。
进一步地，重力检测单元的功能被开启后，可以实现终端设备例如“屏幕方向自动旋转”等功能，对于一些场景下，该功能是根据用户具有需要被选择性的开启的，并非“常开”选 项，本实施例中，通过对该重力检测功能进行检测，在观看直播视频时，提前打开重力检测单元的功能，以实现对终端设备旋转方向的检测，提高使用便捷性。
步骤S203：若开启，则检测终端设备的旋转方向。
进一步的，若检测到重力检测单元被开启，则通过重力检测单元，对终端设备的旋转方向进行检测，其中，重力检测单元例如为三维陀螺仪，具体地实现方式可参加图3所示实施例中步骤S102中的介绍，此处不再赘述。
步骤S204：根据旋转方向，确定显示屏的最大显示长度和最大显示宽度。
可选地，显示屏具有最大显示区域，最大显示区域的长边尺寸为第一长度，最大显示区域的短边尺寸为第二长度，步骤S204包括步骤S2041、S2042两种具体的实现方式：
S2041：当旋转方向为第一方向时，最大显示长度为第一长度，最大显示宽度为第二长度；该第一方向表征终端设备横屏放置时的方向。
S2042：当旋转方向为第二方向时，最大显示长度为第二长度，最大显示宽度为第一长度；该第二方向表征终端设备竖屏放置时的方向。
示例性地，最大显示区域的长边尺寸和短边尺寸，即第一长度和第二长度，记录在终端设备内的硬件信息中，可能通过读取终端设备的硬件信息，可确定最大显示区域的长边尺寸和短边尺寸。进一步的，通过检测终端设备的旋转方向，即终端设备处于横屏方向还是竖屏方向，相应的确定终端设备在处于不同旋转方向时，所能够显示的最大尺寸。更具体地，例如，当终端处于横屏放置时，最大显示长度为终端设备显示屏的长边尺寸，例如1280(像素)，最大显示宽度为终端设备显示屏的短边尺寸，例如720(像素)。而当终端处于竖屏放置时，最大显示长度为终端设备显示屏的短边尺寸，例如720(像素)，最大显示宽度为终端设备显示屏的长边尺寸，例如1280(像素)。
步骤S205：根据待播放视频的视频长宽比，以及显示屏的最大显示长度和最大显示宽度，确定播放尺寸，并以播放尺寸播放视频流。
可选地，播放尺寸包括播放区域长度和播放区域宽度，步骤S205包括步骤S2051、S2052两个具体的实现步骤：
S2051：根据最大显示长度与最大显示宽度的比值，确定显示区域长宽比。
S2052：若显示区域长宽比大于视频长宽比，则播放区域宽度为第二长度，播放区域长度为第二长度与长宽比的乘积；若显示区域长宽比小于视频长宽比，则播放区域长度为第一长度，播放区域宽度为第一长度与视频长宽比的比值。
示例性地，当终端设备的旋转方向确定后，可以确定终端设备在该旋转方向下的显示区域长宽比，进而，根据显示区域长宽比与视频长宽比之间的关系，可以确定显示屏能够承载的用于播放视频流的最大播放尺寸，其中，示例性地，最大播放尺寸即可以为播放尺寸。图7为本公开实施例提供的一种播放尺寸的示意图，如图7所示，播放尺寸包括播放区域长度和播放区域宽度，其中，播放区域可以位于显示屏的中央，显示屏的分辨率为1200*800(像素)。当然，根据需要播放区域也可以位于显示屏的其他位置，此次不再举例。当终端设备位于第一方向，即终端设备横屏放置时，显示区域长宽比为3:2(最大显示宽度为800，最大显示长度为1200)；之后，根据待播放视频的视频长宽比，可分为两种情况，例如，若显示区域长宽比大于视频长宽比，例如视频长宽比为9:16，此时，播放区域宽度为最大显示宽度(800)，播放区域长度为最大显示宽度与视频长宽比的乘积(450)；若显示区域长宽比小于视频长宽 比，例如视频长宽比为16:9，此时，播放区域长度为最大显示长度(1200)，播放区域宽度为最大显示长度与视频长宽比的比值(675)。图8为本公开实施例提供的另一种播放尺寸的示意图，如图8所示，相应地，当终端设备位于第二方向，即终端设备纵屏放置时，显示区域长宽比为2:3(最大显示宽度为1200，最大显示长度为800)；根据待播放视频的视频长宽比，也可分为两种情况，若显示区域长宽比大于视频长宽比，例如视频长宽比为9:16，播放区域宽度为最大显示宽度(1200)，播放区域长度为最大显示宽度与视频长宽比的乘积(675)；若显示区域长宽比小于视频长宽比，例如视频长宽比为16:9，此时，播放区域长度为最大显示长度(800)，播放区域宽度为最大显示长度与视频长宽比的比值(450)。
本实施例中，通过判断终端设备的旋转方向和视频流对应的待播放视频的视频长宽比，确定待播放视频在显示屏的最大播放尺寸，以实现在终端设备发生旋转的情况下，能够以与旋转角度相匹配的最佳的尺寸对待播放视频进行播放，提高视频的显示效果。
可选地，本实施例提供的方法中还包括：
步骤S206：根据旋转方向，对视频流的视频尺寸进行剪裁，以使视频流的视频长宽比与显示区域长宽比匹配。
示例性地，在具体地应用场景下，当终端设备发生旋转时，若视频长宽比与显示区域长宽比相差过大，则可以导致显示屏内剩余较大的空闲区域，而同时，真正的视频流内容，由于屏幕的显示区域有限，导致播放尺寸较小，造成显示效果不佳的问题。本实施例中，在旋转方向变化，而导致视频长宽比与屏幕显示长宽相差较大时，对视频流的视频尺寸进行剪裁，改变视频长宽比，从而实现增加播放尺寸的目的，提高视频的播放效果。
步骤S207：响应于针对触摸显示屏的切换操作，切换目标直播间。
示例性地，切换操作可以为滑动操作，更具体地，例如，用户沿屏幕上下滑动的操作，终端设备对该滑动操作进行响应后，切断当前的目标直播间，也即，切换视频流。在一种可能的实现方式中，切换操作为与旋转方向对应的滑动操作，例如，终端设备横向放置时，横向滑动切换目标直播间；终端设备竖向放置时，竖向滑动切换目标直播间。由于不同目标直播间内的视频流的播放尺寸可能不一致，例如部分视频流适用于横屏播放，而部分适合竖屏播放，用户在旋转终端设备的方向后，响应的操作习惯也会发生变化，因此，本实施例中根据旋转方向对应的滑动操作，控制切换目标直播间，能够提高用户的操作便捷性，防止误操作，提升用户体验。
本实施例中，步骤S201、步骤S203的实现方式与本公开图2所示实施例中的步骤S101、步骤S102的实现方式相同，在此不再一一赘述。
