如前文所简要提及的，在录屏直播场景下，在开播时主播会手动选择或则通过测速推荐来决定开播的清晰度。不同的清晰度对应有不同的基于标准显示器的视频分辨率，例如，清晰度为1080p，对应的分辨率为1920×1080；清晰度为720p，对应的分辨率为1280×720。
录屏直播采集的是终端设备的屏幕内容，某些终端设备的显示分辨率和基于标准显示器的视频分辨率不匹配。例如，手机的显示分辨率为“长条”，即宽度分辨率和高度分辨率的比例超过2：1；平板电脑的显示分辨率中宽度分辨率和高度分辨的比例大概为4：3。
如果采用基于标准显示器的视频分辨率来采集上述终端设备的屏幕内容，会出现下述两种情况：(1)将采集到的源画面完全填满16：9的显示区域，此种方式会导致画面失真；(2)在16：9的显示区域中，先将采集到的屏幕内容填满一边，另一边按照设备屏幕的大小等比缩放，此种方式会导致显示区域上下或左右出现大面积黑边或者裁剪。
本公开的实施例提出了一种用于屏幕内容获取的方案。根据本公开的各种实施例，服务端设备或终端设备确定该终端设备在预定清晰度下以第一分辨率获取终端设备的屏幕内容，第一分辨率对应于所述预定清晰度。基于终端设备的显示分辨率，调整第一分辨率至第二分辨率；以及控制终端设备在预定清晰度下以第二分辨率获取屏幕内容。利用终端设备的显示分辨率，调整预定清晰度对应的第一分辨率至适合或者匹配终端设备的显示分辨率的第二分辨率，并控制终端设备在预定清晰度下以第二分辨率获取屏幕内容。由此，可以在对终端设备的屏幕内容进行录制的情况下可以适应性调整内容的分辨率，从而避免了画面失真，或者显示区域出现黑边或裁剪。
图1示出了本公开的实施例能够在其中实现的示例环境100的示意图。如图1所示，在一些实施例中，环境100可以包括服务器110和终端设备120。在另一些实施例中，环境100可以仅包括终端设备120。
在环境100中包括服务器110和终端设备120时，终端设备120中部署有支持录屏直播的应用、支持检测终端设备性能的应用以及支持对采集到的屏幕内容进行质量评分的应用。或者，服务器110中部署有支持检测终端设备性能的应用以及支持对采集到的屏幕内容进行质量评分的应用，终端设备120中部署有支持录屏直播的应用。
在环境100仅包括终端设备120时，终端设备120中部署有支持录屏直播的应用、支持检测终端设备性能的应用以及支持对采集到的屏幕内容进行质量评分的应用。
在环境100中，终端设备120可以是任意类型的具有计算能力的电子设备，包括终端电子设备或服务端电子设备。终端电子设备可以是任意类型的移动终端、固定终端或便携式终端，包括移动手机、台式计算机、膝上型计算机、笔记本计算机、上网本计算机、平板计算机、媒体计算机、多媒体平板、个人通信系统(PCS)电子设备、个人导航电子设备、个人数字助理(PDA)、音频/视频播放器、数码相机/摄像机、定位电子设备、电视接收器、无线电广播接收器、电子书电子设备、游戏电子设备或者前述各项的任意组合，包括这些电子设备的配件和外设或者其任意组合。服务端电子设备例如可以包括计算系统/服务器，诸如大型机、边缘计算节点、云环境中的电子设备，等等。
服务器110可以是独立的物理服务器，也可以是多个物理服务器构成的服务器集群或者分布式系统，还可以是提供云服务、云数据库、云计算、云函数、云存储、网络服务、云通信、中间件服务、域名服务、安全服务、内容分发网络、以及大数据和人工智能平台等基础云计算服务的云服务器。服务器110例如可以包括计算系统/服务器，诸如大型机、边缘计算节点、云环境中的计算设备，等等。
服务器110与终端设备120之间可以建立有通信连接。通信连接可以通过有线方式或无线方式建立。通信连接可以包括但不限于蓝牙连接、移动网络连接、通用串行总线(Universal Serial Bus，USB)连接、无线保真(Wireless Fidelity，WiFi)连接等，本公开的实施例在此方面不受限制。在本公开的实施例中，服务器110与终端设备120可以通过二者之间的通信连接实现信令交互。
应当理解，仅出于示例性的目的描述环境100的结构和功能，而不暗示对于本公开的范围的任何限制。
图2示出了根据本公开的一些实施例的用于屏幕内容获取的过程200的流程图。在图2中，用于屏幕内容获取的过程200可以被实现在服务器或终端设备中。为了方便讨论，下文中将以服务器执行对终端设备的屏幕内容获取过程为例进行说明。接下来结合图1对本公开提供的用于屏幕内容获取的方案进行详细介绍。应当理解，类似的过程也可以由终端设备120本地执行。
在框210，服务器110响应于确定终端设备120在预定清晰度下以第一分辨率获取终端设备120的屏幕内容，从多个调整模式中确定预定清晰度对应的目标调整模式，第一分辨率对应于预定清晰度。
在一些实施例中，获取终端设备120的屏幕内容可以是在需要实现录屏直播的场景，例如游戏直播或者以终端设备120的屏幕所显示的其他内容进行直播。在录屏直播的场景中，终端设备120可以将获取到的屏幕内容实时地上传服务器110并由服务器110传输给其他终端设备进行播放。
在一些实施例中，录屏直播开始之前，可以由用户手动设置清晰度，或者也可以通过网络测速软件对终端设备120进行网络测速，根据测速结果来向用户推荐清晰度。例如，在网络条件较差的情况下可以选择较低的清晰度；在网络条件较好的情况下，可以选择较高的清晰度。用户选择的清晰度或者网络测速软件推荐的清晰度即为预定清晰度。
在一些实施例中，预定清晰度可以包括多个档位，例如1080p、720p、540p及540p以下的清晰度。如前文所述，不同的清晰度对应有不同的分辨率。在确定终端设备120进行录屏直播时的清晰度后，可以确定该清晰度对应的分辨率。
这里的调整模式指的是对分辨率的调整方式。在一些实施例中，针对终端设备110的屏幕内容的录制过程中，对于不同清晰度可以预先配置对应的调整模式，以用于调整与不同清晰度对应的分辨率。也就是说，在不同清晰度下，可以采用不同的调整方式来确定如何调整采集到的屏幕内容的分辨率。
在一些实施例中，电子设备110的屏幕内容包括在录屏期间电子设备的屏幕上所呈现的画面，例如是正在运行的应用的画面。对于屏幕内容的呈现可以是用户授权的，并且可以由用户选定所要呈现的画面内容。
在框220，服务器110基于终端设备120的显示分辨率，利用目标调整模式来调整第一分辨率至第二分辨率。
在一些实施例中，服务器110中可以配置有多个调整模式，或者服务器110可以从外部调用多个调整模式。
在一些实施例中，调整模式可以包括第一分辨率调整模式、第二分辨率调整模式以及第三分辨率调整模式。为方便描述下文中将“基于标准显示器的视频分辨率”称为“标准分辨率”。将采集终端设备120的屏幕内容的分辨率称为“目标分辨率”。下面对三种分辨调整模式分别进行详细介绍。
第一分辨率调整模式：首先将目标分辨率的宽度分辨率和标准分辨率的宽度分辨率对齐，随后基于终端设备的显示分辨率的宽度分辨率和高度分辨率的比例和目标分辨率的宽度分辨率来确定目标分辨率的高度分辨率。
示例地，第一分辨率调整模式可以采用如下方式实现：
esolution_lrage＝max{Wtarget,Htarget}；
resolution_short＝resolution_lrage/(max｛Wscreen，Hscreen}/min{Wscreen，Hscreen})；
resolution_short mod 2＝0；
其中，Wtarget为标准分辨率的宽度分辨率，Htarget为标准分辨率的高度分辨率，Wscreen为显示分辨率的宽度分辨率，Hscreen为显示分辨率的高度分辨率，resolution_lrage为目标分辨率的宽度分辨率，resolution_short为目标分辨率的高度分辨率，mod为求余函数。
第二种分辨率调整模式：首先将目标分辨率的高度分辨率和标准分辨率的高度分辨率对齐，随后再将目标分辨率的高度分辨率乘以终端设备的显示分辨率的宽度分辨率和高度分辨率的比例来确定目标分辨率的宽度分辨率，随后在对目标分辨率的宽度分辨率进行16对齐修正。
示例地，第二分辨率调整模式可以采用如下方式实现：
resolution_short_temp＝min{Wtarget,Htarget}；
resolution_large_temp＝resolution_short_temp×(max{Wscreen，Hscreen}/min{Wscreen，Hscreen})；
resolution_large＝(resolution_large_temp+16-1)/16×16；
resolution_short＝resolution_lrage/(max{Wscreen，Hscreen}/min{Wscreen，Hscreen})；
resolution_short mod 2＝0；
其中，Wtarget为标准分辨率的宽度分辨率，Htarget为标准分辨率的高度分辨率，Wscreen为显示分辨率的宽度分辨率，Hscreen为显示分辨率的高度分辨率，resolution_lrage为目标分辨率的宽度分辨率，resolution_short为目标分辨率的高度分辨率，resolution_short_temp为中间变量，resolution_large_temp为中间变量，mod为求余函数。
第三种分辨率调整模式：首先确定终端设备的显示分辨率的宽度分辨率和高度分辨率的最大公约数，基于该最大公约数的整数倍分别确定目标分辨率的宽度分辨率和高度分辨率。
示例地，第三分辨率调整模式可以采用如下方式实现：
screen_gcd＝gcd{Wscreen，Hscreen}；
f(n)＝(n×Wscreen/screen_gcd×16)×(n×Hscreen/screen_gcd×16)；
Wcapture＝min_scale×Wscreen/screen_gcd×16；
Hcapture＝min_scale×Hscreen/screen_gcd×16；
其中，Wtarget为标准分辨率的宽度分辨率，Htarget为标准分辨率的高度分辨率，Wscreen为显示分辨率的宽度分辨率，Hscreen为显示分辨率的高度分辨率，Wcapture为目标分辨率的宽度分辨率，Hcapture为目标分辨率的高度分辨率，screen_gcd为显示分辨率的宽度分辨率和高度分辨率的最大公约数，gcd{}标识取最大公约数的函数，min_scale为f(n)取值最小是n的取值。
在一些实施例中，服务器110可以采用上述目标调整模式对第一分辨率进行调整，得到第二分辨率。
例如，预定清晰度为1080p时，服务器110可以采用第一分辨率调整模式，将第一分辨率调整至第二分辨率。在清晰度为1080p时，相比于采用标准分辨率获取终端设备的屏幕内容，采用第一分辨率调整模式调整得到的第二分辨率来获取终端设备的屏幕内容，可以节省终端设备的采集资源和编码资源，还能够优化终端设备的功耗，从而提高获取屏幕内容的流畅性。
例如，预定清晰度为720p时，服务器110可以采用第二分辨率调整模式，将第一分辨率调整至第二分辨率。在清晰度为720p时，相比于采用标准分辨率获取终端设备的屏幕内容，采用第二分辨率调整模式调整得到的第二分辨率来获取终端设备的屏幕内容，可以避免采集终端设备的屏幕内容时画质出现黑边区域或画面被裁剪，以提高画面质量。
例如，预定清晰度为540p及以下清晰度时，服务器110可以采用第三分辨率调整模式，将第一分辨率调整至第二分辨率。在清晰度为540p及以下清晰度时，相比于采用标准分辨率获取终端设备的屏幕内容，采用第三分辨率调整模式调整得到的第二分辨率来获取终端设备的屏幕内容，在终端设备功耗和画质上均有较大的提升。
需要说明的是，上述第一分辨率为前文中所提到的标准分辨率，第二分辨率为前文中所提到的目标分辨率。
前文详细讨论了不同调整模式，并且还提到针对不同清晰度确定更适合的调整模式。下文将详细讨论如何确定每个清晰度对应的目标调整模式。
在一些实施例中，服务器110可以基于终端设备120的性能得分来从多个调整模式中确定预定清晰度对应的目标调整模式。
具体地，服务器110可以分别确定终端设备120在预定清晰度下以多个第三分辨率获取屏幕内容期间的多个性能得分，至少基于多个性能得分确定在预定清晰度下将第一分辨率调整至第二分辨率的目标调整模式。多个第三分辨率是利用不同的多个调整模式分别对第一分辨率进行调整后得到的，因此多个第三分辨率可能是不同的。根据该方案，可以按照不同调整模式对第一分辨率进行调整得到各个第三分辨率。然而，可以在一段时间内控制终端设备120按照各个第三分辨率进行屏幕内容采集，并观察客户端设备在各个第三分辨率下的性能得分。基于观察到的性能得分，可以从多个调整模式中确定针对预定清晰度所要使用的目标调整模式。
在一些实施例中，终端设备120的多个性能得分中每个性能得分可以由终端设备120中的多个组件的性能得分来确定，多个组件与录屏直播时获取屏幕内容的数据处理相关。应当理解，终端设备120的一个性能得分对应于一种调整模式，即由该种调整模式将第一分辨率调整至第三分辨率后，以第三分辨率获取终端设备120的屏幕内容时终端设备120的性能得分。
终端设备120的性能得分可以是基于终端设备120中至少一个组件各自的性能得分来确定。至少一个组件是与录屏直播中获取屏幕内容的数据处理相关的组件。例如，终端设备120的CPU、GPU、内存，等等。
在一些实施例中，至少一个组件各自的性能得分可以基于组件参数-组件性能得分关系曲线确定。例如，可以检测终端设备120中相关组件的性能参数，并采用插值法，由组件参数-组件性能得分关系曲线得到。
在确定终端设备120的性能得分，首先获得终端设备120中至少一个组件的性能得分，然后确定至少一个组件的性能得分的加权平均值、加权和、或者其他运算结果作为终端设备120的性能得分。
示例地，以表1中所示的组件为例：
表1
终端设备120的性能得分例如可以通过以下方式来确定：
应当理解，上述至少一个组件对应的权重值，可以根据需要来进行设置，本公开对此不进行限制。
由于多个第三分辨率是经不同调整模式调整后得到的，以每种第三分辨率采集终端设备120的屏幕内容时，可以得到对应的性能得分。在一些实施例中，可以将终端设备120的性能得分较高的情况下对应的调整模式确定为在预定清晰度下将第一分辨率调整至第二分辨率的目标调整模式。
在一些实施例中，可以通过采集得到的终端设备120的屏幕内容的质量得分来确定采用哪种分辨率算法将第一分辨调整至第二分辨率。
具体地，可以分别确定终端设备120在预定清晰度下以多个第三分辨率获取屏幕内容期间的多个屏幕内容的质量得分，基于多个质量得分确定在预定清晰度下将第一分辨率调整至第二分辨率的调整模式。多个第三分辨率是利用多个调整模式分别对第一分辨率进行调整后得到的。例如可以在一段时间内控制终端设备120按照不同调整模式得到的各个分辨率进行屏幕内容采集，并同时观察客户端设备在各个分辨率下的性能得分和屏幕内容的质量得分。
应当理解，屏幕内容的一个质量得分对应于一种调整模式，即由该种调整模式将第一分辨率调整至第三分辨率后，确定以第三分辨率获取到的终端设备120的屏幕内容的质量得分。
由于多个第三分辨率是经不同调整模式调整后得到的，以每种第三分辨率采集终端设备120的屏幕内容时，可以得到对应的质量得分。在一些实施例中，可以将终端设备120的质量得分较高的情况下对应的调整模式确定为在预定清晰度下将第一分辨率调整至第二分辨率的目标调整模式。
在一些实施例中，可以通过综合考虑终端设备120的性能得分和采集得到的终端设备120的屏幕内容的质量得分来确定采用哪种分辨率算法(即，目标调整模式)将第一分辨调整至第二分辨率。在一些实施例中，可以将终端设备120的至少一个组件的性能得分和屏幕内容的质量得分的加权平均值、加权和、或者其他运算结果作为终端设备120的综合得分。在一些实施例中，可以将终端设备120的综合得分较高的情况下对应的调整模式确定为在预定清晰度下将第一分辨率调整至第二分辨率的目标调整模式。
在框230，服务器110控制终端设备120在预定清晰度下以第二分辨率获取终端设备120的屏幕内容。
在完成分辨率调整后，第二分辨率可以被确定为更适合于终端设备120。因此，在后续屏幕内容的获取过程中，终端设备120将以第二分辨率获取屏幕内容，例如用于录屏直播。
在一些实施例中，在服务器110为终端设备120确定第二分辨率的情况下，服务器110可以将第二分辨率发送给终端设备120，以由终端设备120使用。在一些实施例中，如果过程200被实现在终端设备120处，终端设备120本身将确定调整后得到的第二分辨率，并可以使用第二分辨率来获取屏幕内容。
根据本公开的实施例，可以利用终端设备的显示分辨率，调整预定清晰度对应的第一分辨率至适合或者匹配终端设备的显示分辨率的第二分辨率，以在对终端设备的屏幕内容进行录制的情况下可以适应性调整内容的分辨率，以避免画面失真，或者显示区域出现黑边或裁剪等情况。
图3示出了根据本公开的一些实施例的用于屏幕内容获取的装置300的框图。装置300可以被实现为或者被包括在服务器110或终端设备120中。装置300中的各个模块/组件可以由硬件、软件、固件或者它们的任意组合来实现。
