具体实施方式
应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
本发明提供一种媒体扫描与播放的控制方法。
参照图1，图1为本发明媒体扫描与播放的控制方法一实施例的流程图。
在本实施例中，该媒体扫描与播放的控制方法，包括以下步骤：
S10：注册媒体扫描服务和广播通知服务；
S20：获取外置存储的接入操作和/或媒体中心的进入操作，广播通知媒体扫描服务执行扫描任务；
S30：获取媒体扫描服务的扫描进程，实时更新媒体中心页面上的媒体显示；
S40：获取在媒体中心页面上执行的点击播放操作，控制媒体播放器执行播放；
S50：获取媒体播放器的播放状态，广播通知媒体扫描服务继续扫描或暂停扫描。
在本实施例中，该媒体扫描与播放的控制方法主要用于附带媒体扫描和媒体播放功能的智能设备，一般的智能设备在出厂时都会具备读取自身媒体中心或外置存储设备，并向内部应用程序或服务广播通知，或向外部发送广播通知的功能，也即智能设备的系统附带有媒体扫描服务和广播通知服务，也有些智能设备在出厂时不具备上述媒体扫描服务和广播通知服务，这时就需要先注册一个媒体扫描服务和广播通知服务，以便该智能设备能够读取内部媒体中心的文件，以及接入的外置存储设备。
在用户打开媒体中心或在智能设备上插入外置存储设备时，系统会自动获取所述外置存储的接入操作和/或媒体中心的进入操作，初步分析后创建一扫描该外置存储、或媒体中心、或同时扫描该外置存储和媒体中心的指令，并通过广播通知服务发送至媒体扫描服务，媒体扫描服务收到上述扫描指令后执行扫描所述外置存储和/或媒体中心的任务。
在媒体扫描服务的运行过程中，经过其扫描完成后的媒体文件会及时释放出来，在媒体中心页面上予以显示，获取媒体扫描服务的扫描进程能够得到已完成扫描的媒体文件的实时数据，将其实时更新在媒体中心的显示页面上，能够使得用户及时查看相关的媒体信息，便于用户进行选择操作，用户还可以在看到需要的媒体文件信息后关闭媒体扫描服务，进而降低系统内存的使用率，以保证查看所需媒体文件时系统流畅、不会出现卡顿的情形，增加了用户查看媒体文件的高效性和快捷性。
在媒体中心页面显示出已完成扫描的媒体文件后，用户可以根据需要选择相应的媒体文件，双击或单击操作实现播放，在系统获取到用户执行的双击或单击的点击播放操作时，系统会根据媒体文件的类型匹配相应的媒体播放器执行相应的播放任务，如针对rmvb、MP4、csf、mkv等格式的文件自动加载视频播放器来执行该播放任务，对MP3、wma、wav、au等格式的文件自动加载音频播放器或视频播放器来执行该播放任务，对jpg、jpeg、gif、png、bmp等格式的文件自动加载图片播放器来执行该播放任务。
在媒体播放器运行过程中，由于媒体播放器是否执行播放任务对系统内存的占用比例差别较大，为了避免媒体文件播放时产生卡顿，或媒体扫描出现卡死，系统会实时获取媒体播放器的播放状态，然后通过发送广播通知媒体扫描服务继续扫描或暂停扫描，以保证系统内存的占用在预设的阈值范围内，保证媒体播放和媒体扫描的流畅性。
本实施例的媒体扫描与播放的控制方法，在获取到有外置存储的接入操作和/或进入媒体中心的操作时，系统会广播通知媒体扫描服务执行媒体扫描任务，然后依据获取到的媒体扫描服务的扫描进程，实时更新媒体中心页面上的媒体显示，接着在获取到媒体中心页面上有点击播放的操作时，控制媒体播放器对点击选择的媒体文件进行播放，最后根据获取到的媒体播放器的播放状态，向媒体扫描服务发送广播通知其继续扫描或暂停扫描，解决了媒体扫描与视频播放抢占内存资源和视频播放卡顿的问题，提高了媒体扫描与媒体播放的流畅性。
进一步地，参照图2，基于上述实施例的媒体扫描与播放的控制方法，步骤S20具体包括：
S21：在打开媒体中心和/或外置存储挂载时，控制广播通知服务向媒体扫描服务发送扫描通知；
S22：判断媒体扫描服务是否已经启动，若否，则启动媒体扫描服务，若是，则设置扫描线程执行优先权为1；
S23：获取媒体中心和/或外置存储内待扫描媒体的路径，添加到媒体扫描服务的任务列表集。
在本实施例中，在用户打开媒体中心或插入外置存储挂载，或用户打开媒体中心的同时插入外置存储挂载时，系统会获取到上述操作并向广播通知服务发送指令，指示其向媒体扫描服务发送扫描通知，在所述扫描服务发出之后，系统首先会执行一个媒体扫描服务是否已启动运行的检测判断，在确定媒体扫描服务还未启动运行时，控制其启动运行，在确定媒体扫描服务已经启动运行后，设置其扫描线程执行优先权为1，赋予其较高的执行优先权，执行优先权对应的数值越低，代表其具有越高的优先权等级，执行越频繁，接着系统会获取媒体中心或外置存储挂载内待扫描媒体的路径，或同时获取媒体中心和外置存储挂载内待扫描媒体的路径，在获取外置挂载内待扫描媒体的路径之前，还需要判断该外置存储挂载是否存在开关限制，以提醒用户打开具备开关限制的外置存储挂载的开关，方便系统进行扫描和读取，系统获取上述待扫描媒体的路径后，将其添加至媒体扫描服务的任务列表集中，为了进一步提高用户查看所需媒体文件的速度，系统会统计每次在媒体中心或外置存储挂载内完成扫描的媒体文件中，用户最先点击播放的媒体文件的类型，然后依据统计概率对媒体扫描服务的任务列表集内的扫描任务进行优先级的排序，以使得用户最需要首先查看的媒体文件最先被媒体扫描服务扫描释放，显示在媒体中心页面上。
进一步地，参照图3，基于上述实施例的媒体扫描与播放的控制方法，步骤S30具体包括：
S31：判断是否需要暂停媒体扫描进程，若是，则将所述媒体扫描进程暂停预设时间后，执行所述媒体扫描进程，若否，则继续所述媒体扫描进程；
S32：添加实时扫描结果至数据库，更新至媒体中心页面进行显示。
在本实施例中，在获取到媒体中心和/或外置存储内待扫描媒体的路径，形成媒体扫描任务列表集之后，媒体扫描任务一般就依据所述任务列表集开始对目标媒体文件进行扫描，但是为了进一步保证系统运行的流畅性以及媒体扫描进程的流畅性，在执行媒体扫描之前，会首先判断媒体扫描的needStop标志是否需要暂停扫描，也即是否需要暂停媒体扫描进程，所述needStop为媒体扫描服务的标志位，该标志位能够决定媒体扫描服务的运行状态，主要由系统发送广播通知更改其状态，在系统检测到系统内存已经占用一定比例，媒体扫描服务继续运行时会超过系统内存占用比的预设阈值范围，则系统会广播通知needStop更改为暂停状态，暂停媒体扫描进程，媒体扫描服务进入暂停状态，在暂停预设时间之后再次判断是否需要暂停扫描，如果是，则继续暂停，直至不再需要暂停扫描，暂停的预设时间一般设置在1秒左右，在其他实施例中，可以根据实际情况另行设定，如果媒体扫描服务继续运行时系统内存占用比仍处于预设的阈值范围内，则广播通知needStop更改为继续扫描状态，继续媒体扫描进程，在执行上述两种扫描逻辑后，删除相同路径下的原始数据，以释放更多的存储空间，减少系统内存压力，为了使用户更快地查看到所需的媒体文件，系统会实时添加扫描结果至数据库，以进一步更新至媒体中心页面进行显示，方便用户及时点击查看。
进一步地，参照图4，基于上述实施例的媒体扫描与播放的控制方法，步骤S50具体包括：
S51：获取对媒体播放器执行的播放、暂停、或停止操作，通过自定义广播发送至媒体扫描服务；
S52：判断发送所述自定义广播的媒体播放器的播放状态；
若所述播放状态为暂停或停止，则执行步骤S521，若是，则执行步骤S522，若否，则执行步骤S523；
若所述播放状态为播放，则执行步骤S521，若是，则执行步骤S522，若否，则执行步骤S524，若是，则执行步骤S525，若否，则执行步骤S526;
S521：判断媒体扫描是否完成；
S522：结束媒体扫描进程；
S523：继续所述媒体扫描进程；
S524：获取当前媒体播放与媒体扫描占系统内存的比例，判断该比例是否超过预设阈值；
S525：暂停所述媒体扫描进程；
S526：继续媒体播放和媒体扫描进程。
在本实施例中，在媒体播放器收到执行播放的广播通知后，先对该媒体播放器进行初始化，然后开始执行播放、暂停、或停止事件，系统获取对媒体播放器执行的播放、暂停、或停止操作，创建一个自定义广播发送至媒体扫描服务，该自定义广播携带媒体播放器的播放状态播放、暂停、或停止，有时还可能单独创建一个广播控制接收器，来专门接收携带媒体播放器的播放状态的自定义广播，在媒体扫描服务接收到该自定义广播后，判断其携带的媒体播放器的播放状态，若所述播放状态为暂停或停止，则判断媒体扫描是否完成，若是，则结束媒体扫描进程，若否，则更改needStop标志为继续扫描状态，继续所述媒体扫描进程，若所述播放状态为播放，则判断媒体扫描是否完成，若是，则结束媒体扫描进程，以减少系统内存的占用，若否，则获取当前媒体播放与媒体扫描占系统内存的比例，判断该比例是否超过预设阈值，若是，则更改needStop标志为暂停扫描状态，暂停所述媒体扫描进程，若否，则继续媒体播放和媒体扫描进程。
本发明进一步提供一种媒体扫描与播放的控制装置。
