技术领域
本公开实施例涉及通信技术领域，尤其涉及一种多媒体文件播放播放方法及终端设备。
背景技术
目前，手机视频播放控制的方式通常是通过用户手指滑动进度条滑块或滑动屏幕来调整，又或者是通过快进和快退固定的时间来控制。
但是，一方面，一般相关技术中的控制滑块方式通常难以控制停止的节点，当调整好位置、手指离开时，由于手指皮肤和手机屏幕接触是一个面而不是一个点的特性，因此，手指离开后经常会因为接触面改变而导致节点跳变，导致调整后的播放节点并非为用户想要观看的播放节点，甚至离用户想要观看的播放节点相差很远；并且，手指滑动操作时，有可能会遮挡到视频播放的界面。另一方面，由于固定时间的快进和快退局限性大，无法灵活调节，因此，一般会达不到用户想要的播放速度。
发明内容
本公开实施例提供一种多媒体文件播放控制方法及终端设备，以解决相关技术中通过手指触碰屏幕调节视频播放进度导致播放节点跳变的问题。
为解决上述技术问题，本公开是这样实现的：
第一方面，提供了一种多媒体文件播放控制方法，终端设备包括第一屏幕和第二屏幕，所述方法包括：
接收用户对目标屏的弯折输入，所述弯折输入用于触发第一屏和第二屏之间的折叠角度变化；
响应于所述弯折输入，调节目标多媒体文件的播放参数；
其中，所述目标屏为所述第一屏或所述第二屏；所述播放参数包括播放进度和/或播放速度。
第二方面，提供了一种终端设备，包括第一屏和第二屏，还包括：接收单元，用于接收用户对目标屏的弯折输入，所述弯折输入用于触发所述第一屏和所述第二屏之间的折叠角度变化；
调节单元，用于响应于所述弯折输入，调节目标多媒体文件的播放参数；其中，所述目标屏为所述第一屏或所述第二屏；所述播放参数包括播放进度和/或播放速度。
第三方面，还提供一种计算机可读介质，所述计算机可读介质上存储计算机程序，所述计算机程序被处理器执行时实现如第一方面所述的方法的步骤。
在本公开实施例中，多媒体文件播放控制方法通过接收用户对目标屏的弯折输入(该弯折输入触发第一屏和第二屏之间的折叠角度变化)，以调节目标多媒体文件的播放参数(如播放进度或播放速度)。本公开实施例的方法只需要通过触发第一屏和/或第二屏之间的折叠角度变化即可实现多媒体文件播放进度或播放速度的调节，而无需用户手指触碰或滑动终端设备的屏幕实现视频播放的快进或快退等功能。

具体实施方式
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。
以下结合附图，详细说明本公开各实施例提供的技术方案。
图1是根据本公开一个实施例的多媒体文件播放控制方法的示意性流程图，以解决相关技术中通过手指触碰屏幕调节视频播放进度导致播放节点跳变的问题。本公开实施例的方法应用于包括第一屏和第二屏的终端设备，该方法可包括：
一般，用户在打开并播放终端设备的视频，然后准备观看时，才会有对视频的播放进度进行调节的需求。其中，终端设备可包括第一屏幕和第二屏幕，如终端设备可以为折叠屏手机。
步骤102.接收用户对目标屏的弯折输入，弯折输入用于触发第一屏和第二屏之间的折叠角度变化。
步骤104.响应于弯折输入，调节目标多媒体文件的播放参数(如播放进度和/或播放速度)。其中，目标屏为第一屏或第二屏。
应理解，当用户已经打开并播放终端设备的视频时，此时，用户可通过折叠两个屏幕(即用户对目标屏的弯折输入)中的其中一个屏幕(也可以同时折叠两个屏幕)调节此时视频的播放进度或速度。
由此可见，本公开实施例的多媒体文件播放控制方法通过接收用户对目标屏的弯折输入(该弯折输入触发第一屏和第二屏之间的折叠角度变化)，可以调节目标多媒体文件的播放参数(如播放进度或播放速度)。如此，本公开实施例的方法只需要通过触发第一屏和/或第二屏之间的折叠角度变化即可 实现多媒体文件播放进度或播放速度的调节，而无需用户手指触碰或滑动终端设备的屏幕实现视频播放的快进或快退等功能。
即，用户在观看视频时，可以通过操作折叠另一个屏幕来控制播放进度、播放速度，从而使得控制更加精确和灵活，且在操作的同时不用担心手指遮挡到播放界面。
其中，如图2所示，步骤104中，响应于弯折输入，调节目标多媒体文件的播放参数的操作，可包括：
步骤202.获取弯折输入的弯折方向和折叠角度变化值。
其中，弯折方向可以为朝向用户或者背向用户的方向，又或者，朝向用户正常使用终端设备时用户的左侧方向或右侧方向等等。而折叠的角度可以随着弯折的方向变大或变小等。当然，折叠角度随弯折方向的变化趋势可根据用户的实际用户使用习惯或者其他设定规则进行设置。
步骤204.根据弯折方向，确定第一调节方式。
如，朝向用户正常使用终端设备时用户的左侧方向弯折时，第一调节方式可以为快退调节，而朝向用户正常使用终端设备时用户的右侧方向弯折时，第一调节方式可以为快进调节。又或者，朝向用户的方向弯折时，第一调节方式可以为快进调节，而背向用户的方向弯折时，第一调节方式可以为快退调节。
步骤206.基于第一调节方式和折叠角度变化值，调节目标多媒体文件的播放进度。
应理解，当用户对目标屏做出弯折输入的操作时，可先获取弯折输入的方向以及折叠角度的变化值，以根据折叠方向确定调节方式(如快进还是快退方式)，从而可以根据调节方式以及折叠角度变化值调节目标多媒体文件的播放进度，而无需用户手指触碰或滑动终端设备的屏幕改变视频播放的进度。
具体而言，基于第一调节方式和折叠角度变化值，调节目标多媒体文件的播放进度的操作，可包括：
在第一调节方式为快进调节的情况下，基于折叠角度变化值，控制目标多媒体文件的播放进度快进，其中，快进时长与折叠角度变化值相关。在第一调节方式为快退调节的情况下，基于折叠角度变化值，控制目标多媒体文 件的播放进度快退，其中，快退时长与折叠角度变化值相关。
也就是说，在第一调节方式为快进或快退调节的情况下，当用户开始弯折时，记录开始弯折的位置，并刷新计算屏幕弯折前后的角度，每次刷帧都会重新以刷新后的位置为开始弯折的位置，系统会根据多媒体文件的播放时长和折叠角度根据一定的比例进行增进或回退进度条(如刷新帧率为30FPS，每弯折1度，进度条可增进或回退1度)。
应理解，可以限定为若第一屏和第二屏之间的折叠角度减小，则可以控制多媒体文件的播放进度回退。若第一屏幕和第二屏幕之间的折叠角度增大，则可以控制多媒体文件的播放进度前进。也就是说，当两个屏幕相互靠拢折叠时，可控制多媒体文件的播放进度回退，反之，两个屏幕相互远离折叠时，可控制多媒体文件的播放进度前近。
当然，这里折叠的方向与播放进度是否为快进或快退的匹配可根据实际情况的需求(如用户的习惯等)进行设定，不限于本实施例所限定的情形，即也可以限定为，当两个屏幕相互靠拢折叠时，可控制多媒体文件的播放进度前近，而当两个屏幕相互远离折叠时，可控制多媒体文件的播放进度回退。
在上述实施例中，目标多媒体文件为第一屏和/或第二屏显示的多媒体播放界面播放的文件，多媒体播放界面可包括用于调节多媒体播放进度的进度条。那么，基于第一调节方式和折叠角度变化值，调节目标多媒体文件的播放进度，还可包括：
按照第一调节方式，基于折叠角度变化值，更新进度条上滑块的显示位置。
比如，当需要回退播放时，可将两个屏幕相互靠拢折叠，播放进度条(或者滑块等)回退。即，当用户开始折叠时，根据记录开始折叠的位置，可刷新计算两个屏幕折叠前后之间的角度，每次刷帧都会重新以刷新后的位置为开始折叠的位置，系统会根据视频时长和角度按照一定比例进行回退进度条。如，刷新帧率为30FPS，每折叠1°，进度条回退1°，或者，每折叠2°，进度条回退2°，又或者，每折叠3°，进度条回退3°，又或者，每折叠4°，进度条回退4°，又或者，每折叠5°，进度条回退5°等等，在此不一一举例说明。
同理，当需要加快播放时，可将两个屏幕相互远离折叠，播放进度条(或滑块)增进。即，当用户开始折叠时，根据记录开始折叠的位置，实时刷新计算两个屏幕折叠前后之间的角度，每次刷帧都会重新以刷新后的位置为开始折叠的位置，系统根据视频时长和角度按照一定比例进行增进进度条，如刷新帧率为30FPS，每折叠1°，进度条前进1％。
由此可见，上述任一项申请实施例的方法只需要通过折叠第一屏幕和/或第二屏幕即可实现多媒体文件播放进度的调节，而无需用户手指触碰或滑动终端设备的屏幕实现视频播放的快进或快退，因此，可以解决相关技术中由于手指触碰屏幕调节视频播放进度使得播放节点跳变的问题，从而导致最终播放节点并非为用户想要观看的播放节点，甚至离用户想要观看的播放节点相差很远。即，用户在观看视频时，可通过折叠其中一个屏幕调整控制播放视频进度，从而达到用户想要开始观看视频的播放节点。
并且，也可以解决相关技术中的通过快进和快退固定的时间来控制播放进度的方案，由于固定时间的快进和快退局限性大，而无法灵活调节的问题。
在图3的实施例中，步骤104中的响应于弯折输入，调节目标多媒体文件的播放参数的操作，可包括：
步骤302.获取弯折输入的弯折方向、弯折速度和折叠角度变化值。
其中，弯折方向可以为朝向用户或者背向用户的方向，又或者，朝向用户正常使用终端设备时用户的左侧方向或右侧方向等等。弯折速度一般取决于用户使用终端设备时弯折第一屏和/或第二屏时的速度。而折叠的角度可以随着弯折的方向变大或变小等。当然，折叠角度随弯折方向的变化趋势可根据用户的实际用户使用习惯或者其他设定规则进行设置。
步骤304.根据弯折方向，确定第二调节方式。
如，朝向用户正常使用终端设备时用户的左侧方向弯折时，第二调节方式可以为快退调节(或者为了和第一调节方式相区分开，第二调节方式可以称为快退播放调节)，而朝向用户正常使用终端设备时用户的右侧方向弯折时，第二调节方式可以为快进调节(或者叫快进播放调节)。
步骤306.按照第二调节方式，基于弯折速度和折叠角度变化值，调节目标多媒体文件的播放速度。
应理解，当用户对目标屏做出弯折输入的操作时，可先获取弯折输入的方向、弯折速度以及折叠角度的变化值，以根据折叠方向确定调节方式(如快进还是快退方式)，从而可以根据第二调节方式、弯折速度以及折叠角度变化值调节目标多媒体文件的播放速度，而无需用户手指触碰或滑动终端设备的屏幕改变视频播放的速度。
具体来说，步骤306中的按照第二调节方式，基于弯折速度和折叠角度变化值，调节目标多媒体文件的播放速度的操作，可包括：
在第二调节方式为快进调节的情况下，基于弯折速度和折叠角度变化值，控制目标多媒体文件快进播放，其中，快进速率与弯折速度相关联，快进时长与折叠角度变化值相关。在第二调节方式为快退调节的情况下，基于弯折速度和折叠角度变化值，控制目标多媒体文件快退播放，其中，快退速率与弯折速度相关联，快退时长与折叠角度变化值相关。
应理解，当需要快退播放时，可将两个屏幕相互靠拢折叠，然后将两个屏幕还原到原位(多媒体文件播放进度未调节时的位置或者说两个屏幕并未相互靠拢折叠操作时的位置)，视频进行倍速快退播放。
根据弯折或折叠操作的速度，进行不同倍速(如0.5倍、2倍、4倍等)的快退播放。其中，系统会记录折叠前的位置并在折叠还原后计算出折叠时间，时间越短即速度越快，可根据多个预设阈值输出不同的快退倍数，如大于value1为0.5倍，速度在value1和value2之间为2倍速，大于value2为4倍速，随后系统将会以根据所得值进行倍速快退播放。其中，value1、value2均为预先设置的预设阈值。
同理，当需要快进播放时，可将两个屏幕相互远离折叠并将屏幕还原到原位，视频进行倍速快进播放。其中，根据弯折或折叠操作的速度，进行不同倍速(如0.5倍、2倍、4倍等)的快进播放。其中，系统会记录折叠前的位置并在还原后计算出折叠时间，时间越短即速度越快，可根据多个预设阈值输出不同的快进倍数，如大于value1为0.5倍，速度在value1和value2之间为2倍速，大于value2为4倍速，随后系统将会以根据所得值进行倍速快进播放。
应理解，可根据用户的习惯，改变弯折方向或折叠方向，如原来的方式 是往回折叠(即相互靠拢折叠)为回退，则可改为往后折叠(即相互远离折叠)为回退，而往后折叠为快进则改为往回折叠为快进。
由此可见，本公开实施例的方法可根据折叠的速度对视频进行不同倍速的快进、快退播放，并且可根据用户的喜好选择折叠方向，使得播放控制操作更加灵活多变，以更好满足用户的需求。
即，本公开实施例可以通过折叠屏幕不同的速度来让视频播放的时候达到不同速度的回退播放和快进播放。
在上述进一步的实施例中，本公开实施例的方法还可包括：
若在预设时间段内未检测到第一屏幕和/或第二屏幕的折叠操作，则播放调节后的多媒体文件；或响应于用户的触控操作，播放调节后的多媒体文件。
即，用户停止折叠屏幕后，播放进度滑块则停止移动，系统检测到一定时间内未有滑动操作，则自动继续播放视频。或者，用户可点击播放按钮继续播放视频。
在一个具体的实施例中，结合图4至图7进行说明，本公开实施例的调节多媒体文件播放进度的方法实现过程可以为：
步骤一、用户打开并播放视频。用户使用折叠屏手机打开某视频，并播放观看，可参见图4所示的视频画面。
步骤二、终端设备如手机的系统检测到其中一个屏幕在播放视频的时候，另一个屏幕有折叠操作时，自动暂停播放，此时，用户可以进行折叠屏幕的操作，以调整视频的播放进度。
步骤三、用户通过折叠屏幕，对播放进度进行操作。
回退播放进度：将屏幕往回(两个屏幕相互靠近)折叠，播放进度的滑块401回退，如图5所示。当用户折叠时，记录开始折叠的位置，并可实时刷新计算折叠前后的角度，每次刷帧都会重新以刷新后的位置为开始折叠的位置，系统会根据视频时长和角度按照一定比例进行回退进度条，如刷新帧率为30FPS，每折叠1°，进度条回退1％。
加快播放进度：将屏幕往后(两个屏幕相互远离)折叠，播放进度的滑块401增进，如图6所示。当用户折叠时，记录开始折叠的位置，并可实时刷新计算折叠前后的角度，每次刷帧都会重新以刷新后的位置为开始折叠的 位置，系统根据视频时长和角度按照一定比例进行增进进度条，如刷新帧率为30FPS，每折叠1°，进度条增进1％。
步骤四、完成视频播放控制，继续播放视频。用户停止折叠屏幕，播放进度滑块401停止移动，系统检测到一定时间内未有滑动操作自动继续播放视频或用户点击播放按钮继续播放视频。
由此可见本公开实施例的方法在观看视频时，通过折叠其中一个屏幕调节视频的播放进度，从而达到用户想要观看的视频播放节点。即，用户在观看视频时，可以通过操作折叠一个屏幕来控制播放进度，从而使得控制更加精确和灵活，且在操作的同时不用担心手指遮挡到播放界面。
在另一个具体的实施例中，结合图4至图7进行说明，与上述具体实施例不同的是，本公开实施例可以通过折叠屏幕的速度控制回退播放的速度或快进播放的速度，本公开实施例的方法的具体实现过程可以包括：
首先、用户打开并播放视频。用户使用折叠屏手机打开某视频，并播放观看。
其次、系统检测到在播放视频的时候另一个屏幕有折叠操作时，自动暂停播放，同时弹出菜单让用户选择折叠屏幕时的操作功能，此时，用户可以进行折叠屏幕调整播放进度的操作。
其中、选择操作功能，用户通过折叠屏幕，对播放进度进行操作。
关于调整播放进度的操作可参见上述具体实施例所述的实现过程，在此不做详细赘述。
关于快退播放的操作：将屏幕往回折叠(相互靠近)并还原到原位(多媒体文件播放进度未调节时的位置或者说两个屏幕并未相互靠拢折叠操作时的位置)，此时，视频可进行倍速快退播放，并且，可根据折叠(或者说进度条移动)的速度，进行不同倍速(如0.5倍、2倍、4倍等)的快退播放。
其中，终端设备系统会记录折叠前的位置，并在还原后计算出折叠时间，时间越短即速度越快，然后根据多个阈值输出不同的快退倍数，如大于value1为0.5倍，速度在value1和value2之间为2倍速，大于value2为4倍速，最后系统以所得的倍速值进行倍速快退播放。
关于快进播放的操作：将屏幕往后折叠(相互远离)并还原到原位(多 媒体文件播放进度未调节时的位置或者说两个屏幕并未相互靠拢折叠操作时的位置)，视频可进行倍速快进播放，同时，可根据折叠的速度进行不同倍速(如0.5倍、2倍、4倍等)的快进播放。
具体而言，终端设备的系统会记录折叠前的位置，并在还原后计算出折叠时间，时间越短即速度越快，然后可根据多个阈值输出不同的快进倍数，如大于value1为0.5倍，速度在value1和value2之间为2倍速，大于value2为4倍速，随后系统将会以根据所得值进行倍速快进播放。
在上述方法的实现过程中，可根据用户习惯，改变折叠方向，如上述实施例的方法是以往回折叠屏幕为回退，可改为往后折叠为回退；而上述实施例的方法是以往后折叠屏幕为快进，可改为往回折叠为快进。
再者、完成视频播放控制，继续播放视频。即用户停止折叠屏幕，可重新选择回正常播放速度，进行正常速度播放视频。
由此可见，本公开实施例的方法不仅可以达到上述具体实施例的效果，而且还可根据折叠速度对视频进行不同倍速的快进或快退播放；此外，还可根据用户的喜好选择折叠方向，使得播放控制操作更加灵活多变，以更好地满足用户的需求。即，用户在观看视频时，可以通过操作折叠一个屏幕来控制播放进度和播放速度，从而使得控制更加精确和灵活，且在操作的同时不用担心手指遮挡到播放界面。
即，本公开实施例可以通过折叠屏幕不同的速度来让视频播放的时候达到不同速度的回退播放和快进播放，图5和图6均为左屏播放右屏操作，对于右屏播放左屏操作同样适用。
上述任一项实施例所述的多媒体文件可以为音频文件，也可以为视频文件等等。
本公开实施例还提供一种终端设备，包括第一屏和第二屏，如图8所示，终端设备还包括：接收单元802，用于接收用户对目标屏的弯折输入，弯折输入用于触发第一屏和第二屏之间的折叠角度变化；调节单元804，用于响应于弯折输入，调节目标多媒体文件的播放参数；其中，目标屏为第一屏或第二屏；播放参数包括播放进度和/或播放速度。
由于终端设备通过接收单元802接收用户对目标屏的弯折输入(该弯折 输入触发第一屏和第二屏之间的折叠角度变化)，以通过调节单元804调节目标多媒体文件的播放参数(如播放进度或播放速度)。如此，本公开实施例的终端设备只需要通过折叠第一屏幕和/或第二屏幕即可实现多媒体文件播放进度或播放速度的调节，而无需用户手指触碰或滑动终端设备的屏幕实现视频播放的快进或快退等功能，因此，可以解决相关技术中由于手指触碰屏幕调节视频播放进度使得播放节点跳变的问题，从而导致最终播放节点并非为用户想要观看的播放节点。
在上述实施例中，如图8所示，终端设备还包括第一获取单元806，用于获取弯折输入的弯折方向和折叠角度变化值。调节单元804可配置成根据弯折方向，确定第一调节方式，并基于第一调节方式和折叠角度变化值，调节目标多媒体文件的播放进度。其中，调节单元804还配置成：在第一调节方式为快进调节的情况下，基于折叠角度变化值，控制目标多媒体文件的播放进度快进，其中，快进时长与折叠角度变化值相关；在第一调节方式为快退调节的情况下，基于折叠角度变化值，控制目标多媒体文件的播放进度快退，其中，快退时长与折叠角度变化值相关。
应理解，当用户对目标屏做出弯折输入的操作时，通过第一获取单元806获取弯折输入的方向以及折叠角度的变化值，以通过调节单元804根据折叠方向确定调节方式(如快进还是快退方式)，从而可以根据调节方式以及折叠角度变化值调节目标多媒体文件的播放进度，而无需用户手指触碰或滑动终端设备的屏幕改变视频播放的进度。
在上述任一项实施例中，目标多媒体文件可以为第一屏和/或第二屏显示的多媒体播放界面播放的文件，多媒体播放界面包括用于调节多媒体播放进度的进度条，调节单元804还可配置成：
按照第一调节方式，基于折叠角度变化值，更新进度条上滑块的显示位置。
也就是说，当回退播放目标多媒体文件时，播放进度条(或者滑块等)回退。而当加快播放目标多媒体文件时，播放进度条(或滑块)增进。从而通过播放进度条的显示位置可看出目标多媒体文件的播放位置，即当调节目标多媒体文件播放参数时，进度条的显示位置则与调节播放参数后的位置相 匹配。
在图9的实施例中，本公开实施例的终端设备还可包括第二获取单元808，用于响应于弯折输入，获取弯折输入的弯折方向、弯折速度和折叠角度变化值。调节单元804还可配置成根据弯折方向，确定第二调节方式，并按照第二调节方式，基于弯折速度和折叠角度变化值，调节目标多媒体文件的播放速度。
当用户对目标屏做出弯折输入的操作时，可先通过第二获取单元808获取弯折输入的方向、弯折速度以及折叠角度的变化值，以通过调节单元804折叠方向确定调节方式(如快进还是快退方式)，从而可以根据第二调节方式、弯折速度以及折叠角度变化值调节目标多媒体文件的播放速度，而无需用户手指触碰或滑动终端设备的屏幕改变视频播放的速度。
调节单元804还配置成：在第二调节方式为快进调节的情况下，基于弯折速度和折叠角度变化值，控制目标多媒体文件快进播放，其中，快进速率与弯折速度相关联，快进时长与折叠角度变化值相关；在第二调节方式为快退调节的情况下，基于弯折速度和折叠角度变化值，控制目标多媒体文件快退播放，其中，快退速率与弯折速度相关联，快退时长与折叠角度变化值相关。
由此可见，本公开实施例的方法可根据折叠的速度对视频进行不同倍速的快进、快退播放，并且可根据用户的喜好选择折叠方向，使得播放控制操作更加灵活多变，以更好满足用户的需求。
在上述任一项实施例中，终端设备还可包括播放单元810，其可配置成若在预设时间段内未检测到第一屏和/或第二屏的折叠操作，则播放调节后的目标多媒体文件；或响应于用户的触控操作，播放调节后的目标多媒体文件。
即，用户停止折叠屏幕后，播放进度滑块则停止移动，播放单元810根据系统检测到一定时间内未有滑动的操作自动继续播放视频。或者，可通过用户的点击操作播放按钮继续播放视频。
