Description

音乐缓存方法、装置、电子设备及存储介质
本申请要求在2021年10月26日提交中国专利局、申请号为202111246764.5的中国专利申请的优先权，以上申请的全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及音乐播放技术领域，例如涉及一种音乐缓存方法、装置、电子设备及存储介质。
背景技术
车联网服务已渐渐进入用户的生活，车载娱乐系统是为用户提供服务的媒介，为用户提供车载听觉体验，满足行车过程中的音乐收听需求。
车载娱乐系统通过外接U盘来播放音乐的方式已无法满足用户对丰富及高品质音乐的需求，网络音乐已逐渐应用在车载场景下。但是，网络音乐会涉及加载过程的流量消耗，加载后的缓存存储等状况。在第四代移动通信技术(4th-Generation，4G)网络状态下，通常网速峰值可达到100Mbps，即每秒的传输速度是12.5MB，如果缓存10MB的音乐，在1s内即可完成整首音乐的缓存。在第五代移动通信技术(5th-Generation，5G)网络下，速度则会更快。
但是，车载娱乐系统的流量较于移动智能设备都是较少的，缓存空间也相对较小。如果每次点击播放就缓存整首歌曲，在用户出现切歌等操作时，会导致流量的浪费和缓存空间的资源浪费。

具体实施方式
实施例一
图1为本申请实施例一所提供的一种音乐缓存方法的流程示意图，本实施例可以在音乐播放时对音乐进行缓存，该方法可以由音乐缓存装置来执行，该装置可以通过软件和/或硬件的形式实现，该硬件可以是电子设备，例如，电子设备可以是移动终端，车载终端等。
如图1所述，本实施例的方法包括如下步骤：
S110、当接收到音乐播放指令时，确定与音乐播放指令相对应的目标音乐 是否已存在于缓存列表中。
其中，音乐播放指令可以是进行音乐播放的指令。目标音乐可以是当前想要播放的音乐。缓存列表可以是各个已缓存数据所对应的音乐组成的列表。
例如，当接收到音乐播放指令时，对音乐播放指令进行解析确定音乐播放指令中包含的目标音乐。在缓存列表中，查找是否存在目标音乐，以确定缓存空间中是否存在与目标音乐相对应的已缓存数据。
在一实施例中，当用户想要播放目标音乐时，可以通过选择触发的方式，触发目标音乐，并生成与目标音乐相对应的音乐播放指令。
S120、响应于与所述音乐播放指令相对应的目标音乐不存在于缓存列表中，根据与目标音乐对应的预设初始缓存比例对目标音乐进行缓存，并播放已缓存的目标音乐。
其中，预设初始缓存比例可以是预先设定的缓存比例，例如：目标音乐的10％或20％等，可以根据实际需求进行调整。
例如，若目标音乐不存在于缓存列表中，则表明缓存空间中没有存储目标音乐所对应的已缓存数据，需要进行缓存。此时，可以根据目标音乐对应的预设初始缓存比例对目标音乐进行初步的缓存，并根据缓存的数据播放目标音乐。
S130、根据目标音乐的当前播放进度、当前已缓存比例以及预设后续缓存比例，对目标音乐进行缓存。
其中，当前播放进度可以是目标音乐当前播放的比例。当前已缓存比例可以是当前已缓存数据所占的目标音乐的比例。预设后续缓存比例可以是接下来的阶段可以进行缓存的目标音乐的比例。
例如，在播放目标音乐的过程中，获取目标音乐的当前播放进度，并确定当前缓存比例。进而，当当前播放进度达到继续缓存的条件时，根据当前已缓存比例进行预设后续缓存比例的缓存。
示例性的，当目标音乐的当前播放进度达到预设进度时，可以表明存在继续对目标音乐进行缓存的需求。此时，可以确定当前已缓存比例，确定当前已缓存比例是否达到预设初始缓存比例。若是，则可以基于预设初始缓存比例，继续进行接下来的预设后续缓存比例的目标音乐缓存。若否，则可以基于当前已缓存比例，缓存至预设初始缓存比例，再继续缓存预设后续缓存比例，也可以基于当前已缓存比例缓存至预设初始缓存比例，同时，基于预设初始缓存比例根据预设后续缓存比例进行缓存，即同时缓存。
在上述实施例的基础上，在确定与音乐播放指令相对应的目标音乐是否已 存在于缓存列表中之后，还包括：响应于与所述音乐播放指令相对应的目标音乐存在于缓存列表中，根据缓存列表中的目标音乐进行播放。
例如，若目标音乐存在于缓存列表中，则表明缓存空间中有存储目标音乐所对应的已缓存数据，无需进行缓存。此时，可以根据缓存列表中的目标音乐调取缓存空间中与目标音乐相对应的已缓存数据，并进行播放。
本申请实施例，通过当接收到音乐播放指令时，确定与音乐播放指令相对应的目标音乐是否已存在于缓存列表中；若否，则根据与目标音乐对应的预设初始缓存比例对目标音乐进行缓存，并播放已缓存的目标音乐；根据目标音乐的当前播放进度、当前已缓存比例以及预设后续缓存比例，对目标音乐进行缓存，解决了每次点击播放就缓存整首歌曲，无法根据用户的收听情况进行缓存导致的存储空间和流量浪费的状况，实现了对目标音乐进行边播放边缓存，节省了流量和缓存空间的使用。
实施例二
图2为本申请实施例二所提供的一种音乐缓存方法的流程示意图，本实施例在上述各实施例的基础上，针对后续缓存的方式，以及切歌时的缓存方式可参见本实施例。其中，与上述各实施例相同或相应的术语的解释在此不再赘述。
如图2所述，本实施例的方法包括如下步骤：
S210、当接收到音乐播放指令时，确定与音乐播放指令相对应的目标音乐是否已存在于缓存列表中。
S220、响应于与所述音乐播放指令相对应的目标音乐不存在于缓存列表中，根据与目标音乐对应的预设初始缓存比例对目标音乐进行缓存，并播放已缓存的目标音乐。
S230、若当前已缓存比例与当前播放进度的差值达到预设后续缓存阈值时，则根据当前已缓存比例确定缓存起始点，根据缓存起始点以及预设后续缓存比例对目标音乐进行缓存。
其中，预设后续缓存阈值可以是预先设定的用于触发接下来的缓存的数值。缓存起始点可以是预设后续缓存比例的缓存起始位置。
若当前已缓存比例与当前播放进度的差值达到预设后续缓存阈值时，则确定与当前已缓存比例相对应的缓存起始点。进而，从缓存起始点开始进行缓存，缓存比例为预设后续缓存比例。
例如，在第一次进行后续缓存时，可以是确定预设初始缓存比例为缓存起 始点。在第二次以及第二次之后进行后续缓存时，可以是根据当前已缓存比例确定对应的预设初始缓存比例以及预设后续缓存比例，并确定缓存起始点。
示例性的，预设初始缓存比例20％，预设后续缓存比例为10％。若当前已缓存比例与当前播放进度的差值达到预设后续缓存阈值时，当前已缓存比例为20％，则可以将预设初始缓存比例20％作为缓存起始点。若当前已缓存比例与当前播放进度的差值达到预设后续缓存阈值时，当前已缓存比例为50％，则可以确定缓存起始点为50％，即20％+3×10％。若当前已缓存比例未达到缓存起始点，则可以确定当前已缓存比例对应的缓存起始点。例如，当前已缓存比例为48％，则缓存起始点可以是50％。
若当前已缓存比例未达到缓存起始点，则可以等待当前已缓存比例达到缓存起始点时，从缓存起始点开始后续缓存，也可以同时进行当前已缓存比例到缓存起始点之间的缓存以及从缓存起始点开始的后续缓存。
S240、若在播放目标音乐的过程中接收到切歌指令，则停止目标音乐的播放和缓存，根据播放列表确定待播放音乐，并根据缓存列表，播放待播放音乐。
其中，切歌指令可以是用于从目标音乐切换至待播放音乐的指令。播放列表可以是待播放歌单等将用户想要播放的音乐整合得到的列表。待播放音乐可以是目标音乐所对应的下一首要播放的音乐。
例如，若在播放目标音乐的过程中接收到切歌指令，则表明用户想要停止目标音乐的播放，并想要播放待播放音乐，此时，停止目标音乐的播放和缓存。进而，确定播放列表中与目标音乐相对应的下一首音乐为待播放音乐，并在缓存列表中查找待播放音乐，若找到待播放音乐，则进行播放，若未找到待播放音乐，则边缓存边播放。针对待播放音乐的播放和缓存方式可以是与目标音乐相同的播放和缓存方式。
需要说明的是，若待播放音乐不是播放列表中的音乐，例如：用户触发了一首不在播放列表中的音乐，则可以将用户触发的音乐添加至播放列表中，并确定该首音乐为待播放音乐。
还需要说明的是，播放列表中音乐的播放方式可以是单曲循环，顺序播放和随机播放等，可以根据播放方式确定与目标音乐相对应的待播放音乐。
S250、当当前播放进度达到预设下一首缓存阈值时，获取播放列表中与目标音乐相对应的待播放音乐，并根据预设待播放初始缓存比例对待播放音乐进行缓存。
其中，下一首缓存阈值可以是触发缓存待播放音乐的播放进度值。预设待 播放初始缓存比例可以是在播放目标音乐时，对待播放音乐进行预缓存的缓存比例。
例如，当当前播放进度达到预设下一首缓存阈值时，表明目标音乐即将播放完毕，可以预先缓存下一首音乐。根据播放列表确定与目标音乐相对应的待播放音乐，针对待播放音乐进行预设待播放初始缓存比例的缓存。
例如，预设待播放初始缓存比例和预设初始缓存比例的数值可以是相同的，也可以是不同的，可以根据实际需求设定。通常情况下，预设待播放初始缓存比例小于或等于预设初始缓存比例。
为了对缓存列表进行扩充，以便后续再次播放目标音乐时不用重复缓存，例如，若存在与目标音乐相对应的已缓存数据，则将目标音乐添加至缓存列表中。
其中，已缓存数据可以是针对目标音乐缓存的数据，可以是目标音乐的全部缓存数据，也可以是目标音乐的部分缓存数据。
例如，若针对目标音乐进行了缓存操作，则存在与目标音乐相对应的已缓存数据，可以将目标音乐添加至缓存列表中，以便在后续对目标音乐进行播放时调用缓存空间中的已缓存数据进行播放。若已缓存数据是目标音乐的部分缓存数据，则可以播放已缓存数据，并继续缓存后续的缓存。
为了能够及时对缓存空间进行清理，例如，若满足预设清理条件时，对缓存空间中的音乐缓存进行清理。
其中，预设清理条件可以是预先设置的触发清理的条件，例如：缓存空间中的音乐缓存达到清理阈值，或者，缓存空间中的音乐缓存的未调用时长达到未调用时长阈值等。
例如，当检测到缓存空间中的音乐缓存达到预设清理条件时，根据预先设定的清理规则对缓存空间中的音乐缓存进行清理。例如：根据先进先出原则对音乐缓存进行清理，或者，将未调用时长达到未调用时长阈值的音乐缓存进行清理。
本申请实施例，通过当接收到音乐播放指令时，确定与音乐播放指令相对应的目标音乐是否已存在于缓存列表中；若否，则根据与目标音乐对应的预设初始缓存比例对目标音乐进行缓存，并播放已缓存的目标音乐；根据目标音乐的当前播放进度、当前已缓存比例以及预设后续缓存比例，对目标音乐进行缓存，以在播放的同时进行分段缓存，若在播放目标音乐的过程中接收到切歌指令，则停止目标音乐的播放和缓存，根据播放列表确定待播放音乐，并根据缓 存列表，播放待播放音乐，以避免在用户不需要目标音乐的情况下对目标音乐进行全部缓存，若在播放目标音乐的过程中接收到切歌指令，则停止目标音乐的播放和缓存，根据播放列表确定待播放音乐，并根据缓存列表，播放待播放音乐，以提前对待播放音乐进行预缓存，提高用户体验度，解决了每次点击播放就缓存整首歌曲，无法根据用户的收听情况进行缓存导致的存储空间和流量浪费的状况，实现了对目标音乐进行边播放边缓存，节省了流量和缓存空间的使用。

图4为本申请实施例三所提供的一种音乐缓存方法的流程示意图。如图4所述，本实施例的方法包括如下步骤：
1、点击播放歌曲A(目标音乐)，播放控制子模块触发缓存判断。
2、判断歌曲A是否在缓存列表中，若歌曲A在缓存列表中，则进行播放输出，若歌曲A不在缓存列表中，则执行3。
3、通过缓存配置子模块中预设的初始缓存比例执行缓存，并通过播放输出子模块进行播放。
4、判断是否出现切歌操作，若出现切歌操作，则停止对歌曲A的缓存，并根据播放列表对下一首歌曲进行缓存和播放，若未出现切歌操作，则执行5。
5、通过缓存配置子模块中的递进缓存比例执行缓存，当播放进度达到预缓存的上一首播放进度阈值时，按照预缓存策略根据播放列表对下一首歌曲进行缓存和播放。
6、在缓存歌曲A的过程中，判断歌曲A的缓存是否完整，若歌曲A的缓存完整，则将歌曲A加入缓存列表中，若歌曲A的缓存不完整，则通过缓存配置子模块中的递进缓存比例执行缓存。
