这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本说明书一个或多个实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本说明书一个或多个实施例的一些方面相一致的装置和方法的例子。

云桌面服务，也称之为虚拟桌面服务，是指一种运用云技术，将部署在云端的应用，并通过一个桌面的形式，将部署在云端的应用提供给用户进行远程访问的技术。例如，在实际应用中，部署在云端的应用，通常在云端运行，而在运行过程中产生的画面和声音，可以通过传输协议，实时的传输到客户端。
由于云桌面服务，具有集中管理、安全可靠、节约成本、绿色节能等优势。使得用户可以突破时间、地点、终端、应用的限制，随时随地接入到云端桌面。
在实际应用中，由于部署在云端的应用在运行过程中产生的画面和声音，通常都是通过网络传输到客户端，由客户端面向用户进行展现和播放；因此，一旦网络出现网络抖动和延时，就会导致传输到客户端的画面和声音不连续，有噪音等问题，进而影响用户体验。
有鉴于此，本说明书提出一种客户端在远程访问云服务端上部署的应用程序时，根据该应用程序对应的播放场景，来动态的对客户端搭载的物理播放硬件进行播放配置的技术方案。
在实现时，在云服务端上，可以运行了供客户端远程访问的若干应用程序。而云服务端可以维护一个与所述客户端搭载的物理播放硬件对应的虚拟播放硬件。上述若干应用程序中可以包括至少一个具有该虚拟播放硬件的使用需求的目标应用程序。
当客户端在对上述目标应用程序进行远程访问时，可以获取该目标应用程序针对所述虚拟播放硬件的使用数据，并基于该使用数据确定与上述目标应用程序对应的播放场景；然后，可以将确定出的播放场景发送至所述客户端，以使客户端可以根据该播放场景对应的播放配置参数，对上述物理播放硬件进行播放配置。
在以上技术方案中，由于可以在客户端远程访问云服务端上的目标应用程序时，根据该目标应用程序对应的播放场景，动态的对该客户端搭载的物理播放硬件进行播放配置；因此，使得物理播放硬件的播放效果能够更加的适配该目标应用程序当前的播放场景，进而可以提高用户的音视频播放体验。
图1是一示例性实施例提供的一种播放参数配置方法的架构示意图。如图1所示，该***可以包括网络10、服务端11、若干客户端，如台式电脑12，笔记本电脑13，手机14等。
服务端11可以包含一***立主机的服务器，或者该服务端11可以为主机集群承载的虚拟服务器，云服务器等。客户端12-14只是用户可以使用的一种电子设备。实际上，用户还可以使用注入下述类型的电子设备：平板设备、掌上电脑(PDAs，Personal Digital Assistants)等，本说明书一个或多个实施例并不对此进行限制。网络10可以包括多种类型的有线或无线网络。
在一实施例中，服务端11客户端12-14进行配合；其中，服务端11可以运行了供客 户端远程访问的若干应用程序，服务端11还可以维护了与所述客户端搭载的物理播放硬件对应的虚拟播放硬件，由于应用程序都是运行在服务端11，当用户通过客户端12-14访问应用程序时，播放数据可以通过网络传输到客户端12-14，由客户端12-14解析后向用户进行播放。由于网络抖动和延时等问题，可能会导致播放出现不连续，不同步，噪音较多等问题。基于此，服务端11可以获取客户端12-14远程访问目标应用程序后针对虚拟播放硬件的使用数据，然后基于本说明书的播放参数配置方案，对客户端12-14搭载的物理播放硬件进行播放配置。
下面结合附图对本说明书的播放参数配置方案进行详细说明。
图2是一示例性实施例提供的一种播放参数配置方法的流程图。如图2所示，该方法应用于云服务端，该云服务端例如可以为图1所述的服务端11，其中云服务端运行了供客户端远程访问的若干应用程序，还可以维护了与所述客户端搭载的物理播放硬件对应的虚拟播放硬件，其中供客户端远程访问的若干应用程序中，包括至少一个具有所述虚拟播放硬件的使用需求的目标应用程序。该方法可以包括以下步骤：
步骤202，响应于所述客户端对所述目标应用程序的远程访问，获取所述目标应用程序针对所述虚拟播放硬件的使用数据；
上述虚拟播放硬件，具体可以是云服务端维护的，与客户端搭载的物理播放硬件对应的虚拟播放硬件。其中，与该物理播放硬件对应的虚拟播放硬件，可以理解为是部署在云服务端的操作***中的，与上述物理播放硬件对应的一个虚拟服务，使得部署在云服务端的应用程序，可以通过发起针对该虚拟播放硬件的调用，来便捷的完成针对上述物理播放硬件的远程调用。
例如，在实际应用中，云服务端上部署的应用程序，可能会具有客户端搭载的物理播放硬件的使用需求，为了便于该应用程序调用该物理播放硬件，可以在云服务端的操作***中，创建一个与该物理播放硬件对应的虚拟播放硬件，并赋予该应用程序针对该虚拟播放硬件的调用权限，使得用户在远程访问云服务端上部署的该应用程序时，该客户端可以通过发起针对该虚拟播放硬件的调用，来完成针对上述物理播放硬件的远程调用。
其中，需要说明的是，该虚拟播放硬件具体的硬件类型，在本说明书中不进行特别限定。例如，在示出的一种实施方式中，上述虚拟播放硬件具体可以包括虚拟麦克风及虚拟扬声器，等等。
上述目标应用程序，具体可以包括任意类型的具有虚拟播放硬件的使用需求的云端运行的应用程序。例如，在实际应用中，具体可以是视频通话程序或是音乐播放程序。其中，视频通话程序具有虚拟麦克风以及虚拟扬声器的使用需求；音乐播放程序具有虚拟扬声器的使用需求。
本说明书所述的虚拟播放硬件的使用数据，可以包括任意类型的能够描述该虚拟播放硬件是否正在被使用的数据，例如，可以是虚拟播放硬件的使用情况的状态。
本说明书描述的获取所述目标应用程序针对所述虚拟播放硬件的使用数据；具体可以是用户通过客户端访问云端应用程序时，云端应用程序自动获取云端应用程序针对虚拟播放硬件的使用数据。
例如，在实际应用中，当用户通过客户端远程访问云服务端提供的视频通话程序时，用户访问该视频通话程序进行视频通话，此时虚拟麦克风及虚拟扬声器均正在被使用，云服务端可以获取到该虚拟扬声器及虚拟麦克风的使用数据。又例如，当用户通过客户端远程访问云服务端提供的音乐播放程序时，用户访问该音乐播放程序播放音乐，此时虚拟扬声器正在被使用，云服务端可以获取到该虚拟扬声器的使用数据。
在一种实施例中，云服务端通过搭载虚拟操作***，对应用程序及虚拟播放硬件进行管理，可以获取虚拟播放硬件是否为已使用状态。其中，应用程序在云服务端搭载的操作***中，注册了针对所述虚拟播放硬件的调用监听；云服务端维护了用于指示目标应用程序针对虚拟播放硬件使用情况的状态。
在上述获取目标应用程序针对播放硬件的使用数据之前，可以通过获取虚拟播放硬件的使用情况的状态，作为虚拟播放硬件的使用数据。图3是一示例性实施例提供的一种获取虚拟播放硬件使用数据的流程图，如图3所示，该可以包括以下步骤：
步骤202a，监听所述目标应用程序针对所述虚拟播放硬件的调用事件；
本说明书所述的虚拟操作***，可以模拟和现有操作***相同的环境，该操作运行在云服务端，用户可以通过客户端远程访问该虚拟操作***，在虚拟操作***上可以运行多种应用程序，包括上述具有所述虚拟播放硬件的使用需求的目标应用程序。在该虚拟操作***中，目标应用程序可以注册针对虚拟播放硬件的调用监听，通过监听目标应用程序针对虚拟播放硬件的调用事件，来确定虚拟播放硬件是否被使用。
步骤202b，响应于监听到的所述目标应用程序针对所述虚拟播放硬件的调用事件，将所述云服务端维护的所述状态由未使用状态切换为使用状态。
云服务端维护了用于指示目标应用程序针对虚拟播放硬件的使用情况的状态，该状态可以包括使用状态和未使用状态。在实际应用中可以用active状态来表示使用状态，即虚拟播放硬件正在被使用。当云服务端监听到目标应用程序针对上述虚拟播放硬件的调用事件后，响应于该调用事件，将云服务端维护的用于指示目标应用程序针对虚拟播放硬件使用情况的状态由未使用状态切换使用状态。
在一种实施例中，可以将云服务端维护的用于指示目标应用程序针对虚拟播放硬件使用情况的状态，作为所述目标应用程序针对所述虚拟播放硬件的使用数据。
例如，当用户通过客户端访问云服务端的提供视频通话程序，用户访问该视频通话程序进行视频通话，此时可以监听到该视频通话程序正在调用虚拟扬声器和虚拟麦克风，云服务端可以响应于音乐播放程序针对虚拟扬声器和虚拟麦克风的调用事件，将云服务端维护的上述用于指示视频通话程序针对虚拟扬声器使用情况的状态切换为使用状态，以及将云服务端维护的上述用于指示视频通话程序针对虚拟麦克风使用情况的状态切换为使用 状态，并将该使用状态作为虚拟扬声器和虚拟麦克风的使用数据。
又例如，当用户通过客户端远程访问云服务端提供的音乐播放程序，用户访问该音乐播放程序播放音乐，此时可以监听到该音乐播放程序正在调用虚拟扬声器，云服务端可以响应于音乐播放程序针对虚拟扬声器的调用事件，将云服务端维护的上述用于指示音乐播放程序针对虚拟扬声器使用情况的状态切换为使用状态，并将该使用状态作为虚拟扬声器的使用数据。
在另一种实施例中，云服务端的应用程序在云服务端搭载的虚拟操作***中，注册了针对所述虚拟播放硬件的调用监听之前；云服务端搭载的虚拟操作***注册了针对虚拟播放硬件的调用监听。云服务端搭载的虚拟操作***可以获取虚拟播放硬件是否为已使用状态。当虚拟操作***监听到虚拟播放硬件为已使用状态时，此时说明有新的应用程序正在使用虚拟播放硬件，云服务端注册该应用程序针对虚拟播放硬件的调用监听。
也即，云服务端同时监听虚拟操作***针对上述虚拟播放硬件和目标应用程序针对上述虚拟播放硬件的调用事件。当监听到虚拟操作***针对上述虚拟播放硬件的调用事件后，且没有监听到目标应用程序针对上述虚拟播放硬件的调用事件。此时说明有新的应用程序正在使用虚拟播放硬件，云服务端为该新的应用程序注册针对上述虚拟播放硬件的调用事件。
步骤204，基于所述使用数据确定与所述目标应用程序对应的播放场景；
如前所述，上述使用数据可以为云服务端维护的用于指示目标应用程序针对虚拟播放硬件使用情况的状态，当监听到虚拟播放硬件被目标应用程序调用事件时，将该状态由未使用状态切换未使用状态，作为上述目标应用程序针对所述虚拟播放硬件的使用数据。
本说明书所述的目标应用程序对应的播放场景，可以包括视频通话场景和音乐播放场景。其中，当目标应用程序正在使用虚拟麦克风时，可以确定目标应用程序对应的当前播放场景为视频通话场景。当目标应用程序正在使用虚拟扬声器且没有使用虚拟麦克风时，可以确定目标应用程序对应的当前播放场景为音乐播放场景。
在一种实施例中，如果所述云服务端维护的指示所述目标应用程序针对所述虚拟麦克风的使用情况的状态为已使用状态，确定与所述目标应用程序对应的播放场景为通话场景；如果所述云服务端维护的指示所述目标应用程序针对所述虚拟扬声器的使用情况的状态为已使用状态，并且所述云服务端维护的指示所述目标应用程序针对所述虚拟麦克风的使用状况的状态为未使用状态，则确定与所述目标应用程序对应的播放场景为音乐播放场景。
例如，当用户通过客户端访问云服务端提供的视频通话程序，用户访问该视频通话程序进行视频通话，此时可以监听到该视频通话程序正在调用虚拟扬声器和虚拟麦克风，云服务端可以响应于音乐播放程序针对虚拟扬声器和虚拟麦克风的调用事件，将云服务端维护的上述用于指示视频通话程序针对虚拟扬声器使用情况的状态切换为使用状态，以及将云服务端维护的上述用于指示视频通话程序针对虚拟麦克风使用情况的状态切换为使用状态。此时，由于虚拟麦克风为使用状态，可以确定当前的播放场景为视频通话场景。
又例如，当用户通过客户端远程访问云服务端提供的音乐播放程序，用户访问该音乐播放程序播放音乐，此时可以监听到该音乐播放程序正在调用虚拟扬声器，云服务端可以响应于音乐播放程序针对虚拟扬声器的调用事件，将云服务端维护的上述用于指示音乐播放程序针对虚拟扬声器使用情况的状态切换为使用状态。此时，由于虚拟扬声器为使用状态且虚拟麦克风部位使用状态，可以确定当前播放场景为音乐播放场景。
在另一种实施例中，云服务端可能同时运行多个应用程序，因此云服务端还维护了虚拟播放硬件的使用计数，用于指示当前播放硬件的使用数量。其中虚拟播放硬件的使用计数可以包括虚拟麦克风的使用计数和虚拟扬声器的使用计数。
如果所述云服务端维护的指示所述目标应用程序针对所述虚拟麦克风的使用情况的状态为已使用状态，此时虚拟麦克风的使用计数加一；如果所述云服务端维护的指示所述目标应用程序针对所述虚拟扬声器使用情况的状态为已使用状态，此时虚拟扬声器的使用计数加一；当目标应用程序停止使用虚拟播放硬件时，云服务端维护的上述状态由使用状态切换为未使用状态，此时虚拟硬件的使用计数减一。当虚拟麦克风的使用计数大于一时，可以确定目标应用程序对应的当前播放场景为视频通话场景；当虚拟扬声器的使用计数大于一时且虚拟麦克风的使用计数为0时，可以确定目标应用程序对应的当前播放场景为音乐播放场景。
例如，当用户通过客户端同时访问云服务端提供的视频通话程序和音乐播放程序，用户访问该视频通话程序进行视频通话也访问该音乐播放程序进行播放音乐。此时可以监听到该视频通话程序正在调用虚拟扬声器和虚拟麦克风，也可以监听到该音乐播放程序正在调用虚拟扬声器。云服务端可以响应于视频通话程序针对虚拟扬声器和虚拟麦克风的调用事件，将云服务端维护的上述用于指示视频通话程序针对虚拟扬声器使用情况的状态切换为使用状态，并将上述虚拟扬声器的使用计数加一；以及将云服务端维护的上述用于指示视频通话程序针对虚拟麦克风使用情况的状态切换为使用状态，并将上述虚拟麦克风的使用计数加一。同时，云服务端可以响应于音乐播放程序针对虚拟扬声器的调用事件，由于虚拟扬声器已为使用状态，将虚拟扬声器的使用计数加一。此时虚拟麦克风的使用计数为一，虚拟扬声器的使用计数为二，由于虚拟麦克风的使用计数大于一即被认为是视频通话场景。此时目标应用程序对应的播放场景为视频通话场景。
通过上述步骤，云服务端通过获取目标应用程序针对所述虚拟播放硬件的使用数据；并基于所述使用数据可以确定所述目标应用程序对应的播放场景；下面结合图4，通过一个具体实施例进一步解释该确定播放场景的过程。
图4是一示例性实施例提供的一种确定播放场景的流程图。
如图4所示，云服务端搭载的虚拟操作***注册了针对虚拟播放硬件的调用监听(402)，当监听到虚拟操作***针对虚拟播放硬件的调用事件时(404)，说明虚拟播放硬件正在被使用，此时判断是否为新的应用程序正在使用虚拟播放硬件(406)，如果没有监听到应用程序针对虚拟播放硬件调用事件，说明为新的应用程序正在使用虚拟播放硬件，此时 云服务端对这个应用程序注册针对虚拟播放硬件的调用事件(408)。当监听到应用程序针对虚拟播放硬件的调用硬件时(410)，将云服务端维护的用于指示目标应用程序针对虚拟播放硬件使用情况的状态，由未使用状态切换至使用状态(412)，将云服务端维护的用于指示当前虚拟播放硬件的使用数量的虚拟播放硬件的使用计数加一(414)，通过上述虚拟播放硬件的使用计数确定当前应用程序对应的播放场景。如果虚拟麦克风的使用计数大于一，则当前播放场景为视频通话场景，如果虚拟扬声器的使用计数大于一且虚拟麦克风的使用计数等于零，则当前播放场景为音乐播放场景。
步骤206，将确定出的所述播放场景发送至所述客户端，以使所述客户端根据所述播放场景对应的播放配置参数对所述物理播放硬件进行播放配置。
通过上述步骤可以确定目标应用程序对应的播放场景，其中播放场景可以包括视频通话场景或者音乐播放场景。云服务端可以将视频通话场景或者音乐播放场景发送至客户端，使客户端根据上述播放场景对物理播放硬件进行播放配置。其中客户端针对不同应用程序对应的播放场景预先设置了不同的播放配置参数，根据不同的播放配置参数，对客户端搭载的物理播放硬件进行配置，用户可以根据实际需要自行调整预先设置的播放配置参数，本发明对此不作限定。
在一种实施方式中，上述播放配置参数可以包括与播放硬件相关的播放优化配置参数，客户端可以根据优化配置参数对上述物理播放硬件进行播放优化配置。其中，对物理播放硬件进行播放优化配置参数可以包括，设置音频抗网络抖动缓存的大小，回波抵消，噪声抑制，变速播放等级优化，音视频同步优化等等，相关内容可以参考相关音视频播放优化技术，本说明书不再赘述。
例如，当用户通过客户端访问云服务端提供的视频通话程序时，此时播放场景为视频通话场景。由于视频播放场景对音频传输要求较高，如果网络抖动较大，用户的视频通话体验较差。此时可以增加音频抗网络抖动缓存的大小，提高音频抗网络抖动的能力，以此提高用户体验。
在另一个例子中，当用户通过客户端访问云服务端提供的视频通话程序时，此时播放场景为视频通话场景。由于视频通话场景时，物理麦克风可以采集到用户的音频数据，而在采集数据时可能出现噪音，回波等情况。此时由于是视频通话场景，可以自动设置回波抵消，噪声抑制等功能，以此提高用户的使用体验。
在另一个例子中，当用户通过客户端访问云服务端提供的音乐播放程序时，此时播放场景为音乐播放场景。用户在播放音乐时，可能会使用音乐播放程序提供的倍速功能，比如二倍速，三倍速；由于播放数据都是通过网络从云端传输至客户端，如果出现网络抖动等问题，可能出现音频不连续等问题。此时由于播放场景，可以自动开启变速播放等级优化，以提高用户体验；具体实现方法可以参考相关技术，本说明书不再赘述。
在另一个例子中，当用户通过客户端访问云服务端提供的视频通话程序时，此时播放场景为视频通话场景。在视频通话中，由于网络延时，抖动等情况，可能会出现音画不同 步等情况。此时由于是视频通话场景，可以自动开启音视频同步优化，以提高用户体验；具体实现方法可以参考相关技术，本说明书不再赘述。
在一种实施方式中，云服务端维护了用于区分不同应用程序对应的播放场景的场景值，其中场景值可以具体为数字，英文标识或是其他用于区分不同的播放场景的值，本说明书不作特别限定。云服务端可以确定目标应用程序对应的播放场景的场景值，将确定出的场景值发送至客户端，客户端可以预先设置不同场景值对应的播放配置参数，客户端可以根据不同场景值对应的播放配置参数，对客户端搭载的物理播放硬件进行播放优化配置。
在另一种实施方式中，云服务端确定目标应用程序对应的播放场景后，将上述播放场景发送至客户端之前，可以获取播放场景对应的传输配置参数，基于获取到的所述传输配置参数对所述目标应用程序进行传输配置，以使所述目标应用程序根据所述传输配置参数向所述客户端传输待播放数据。其中，上述传输配置参数可以包括与数据传输相关的传输优化配置参数，云服务端可以根据传输优化配置参数对播放数据传输前进行优化配置。
云服务端可以针对不同应用程序对应的播放场景预先设置了不同的传输优化配置参数，根据不同的传输配置参数，对服务端运行的应用程序进行传输优化配置，用户可以根据实际需要自行调整预先设置的传输配置参数，本发明对此不作限定。
在另一种实施方式中，服务端还可以确定目标应用程序对应的播放场景的场景值，根据场景值获取播放场景对应的传输优化配置参数，基于获取到的所述传输配置参数对所述目标应用程序进行传输优化配置，以使所述目标应用程序根据所述传输配置参数向所述客户端传输待播放数据。
在一种实施方式中，上述传输配置参数可以包括与待播放数据对应的传输优先级。例如，当用户通过客户端访问云服务端提供的视频通话程序，此时播放场景为视频通话场景，由于视频播放场景对音频传输要求较高，此时可以提高视频通话程序针对通话的音频数据的传输优先级，保证通话音频数据的传输，提高音频通话的流畅度，提高用户视频通话的体验。
在另一个例子中，当用户通过客户端访问云服务端提供的音乐播放程序时，此时播放场景为音乐播放场景，此时可以提高音乐播放程序针对音乐播放数据的传输优先级，保证音乐播放数据的传输，提高用户的音乐播放体验。
通过上述步骤，云服务端通过获取目标应用程序针对所述虚拟播放硬件的使用数据；并基于所述使用数据可以确定所述目标应用程序对应的播放场景；基于目标应用程序对应的播放场景，对目标应用程序进行传输配置优化；并将目标应用程序对应的播放场景发送至客户端，以使客户端根据所述播放场景对应的播放配置参数对所述物理播放硬件进行播放优化配置。通过对不同场景配置不同的传输配置参数及播放配置，能够提高用户在访问云服务端运行的应用程序时的音视频体验。下面结合图5，通过一个具体实施例进一步解释通过播放场景进行播放参数配置的过程。
图5是一示例性实施例提供的一种配置播放参数的流程图。
如图5所示，云服务端可以确定目标应用程序对应的播放场景具体是音乐播放场景还是视频通话场景(502)，当确定目标应用程序对应的播放场景后，可以获取播放场景对应的场景值(504)，获取场景值后，在云服务端根据场景值获取传输配置参数(506)，对云服务端运行的应用程序进行传输配置，通过配置不同待播放数据对应的音视频传输优先级，对音视频数据传输进行优化；同时，云服务端可以将场景值发送至客户端，使客户端根据场景值对应的播放配置参数进行播放配置，以提高用户访问云端应用程序时的音视频体验。
图6是一示例性实施例提供的一种设备的示意结构图。请参考图6，在硬件层面，该设备包括处理器602、内部总线604、网络接口606、内存608以及非易失性存储器610，当然还可能包括其他业务所需要的硬件。本说明书一个或多个实施例可以基于软件方式来实现，比如由处理器602从非易失性存储器610中读取对应的计算机程序到内存609中然后运行。当然，除了软件实现方式之外，本说明书一个或多个实施例并不排除其他实现方式，比如逻辑器件抑或软硬件结合的方式等等，也就是说以下处理流程的执行主体并不限定于各个逻辑单元，也可以是硬件或逻辑器件。
