具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
随着电子设备的硬件性能的提升，更多的电子设备可以支持进行视频播放。例如，电子设备可以运行视频播放客户端，然后通过该视频播放客户端来对从网络请求的视频进行播放，或者可以通过运行网页浏览器，然后通过在网页浏览器中进行视频播放，再或者电子设备可以通过视频播放软件对本地存储的视频文件进行播放。
而无论对于是在网络上传输播放的视频，还是在本地存储的视频，在视频被生成的时候，为了能够降低对存储空间的占用以及便于在网络上传输，都会对生成的视频进行压缩。那么相应的，电子设备在获取到视频时，先获取的到也会是压缩编码以后的视频，那么在这种情况下，电子设备会先对已经压缩编码的视频进行视频解码。
通常，如图1所示，电子设备可以通过硬解码以及软解码两种方式来进行视频解码。其中，硬解码是指使用非CPU进行解码，如GPU(Graphics Processing Unit)、专用的DSP、FPGA、ASIC芯片等。而软解码是指使用CPU进行解码。
具体地，如图1所示，MediaFramework(多媒体框架)通过与客户端或者网页浏览器的API接口获取待播放的视频文件，并交由Video Decode(视频解码 器)，其中，Media Framework(多媒体框架)为操作系统中多媒体框架。
不论是硬解码还是软解码，在将视频数据解码之后，会将解码后的视频数据发送至SurfaceFlinger(图层传递模块)，由SurfaceFlinger将解码后的视频数据渲染和合成之后，在屏幕上显示。其中，SurfaceFlinger是一个独立的Service，它接收所有的Surface作为输入，根据ZOrder、透明度、大小、位置等参数，计算出每个Surface在最终合成图像中的位置，然后交由HWComposer或OpenGL生成最终的显示Buffer，然后显示到特定的显示设备上。
而发明人发现无论是在硬解码还是软解码过程中都可以加入视觉增强过程，从而使得后续所播放的视频有更高的视觉效果。例如，可以基于HQV(hollywood quality video)技术对视频进行边缘去燥、调节曝光度或者提升清晰度等。此外，还可以通过其他的方式来提升所播放视频的视觉体验，例如，提升颜色艳丽程度等。
但是，发明人进一步的发现，对于是否对所播放的视频进行视觉增强的控制方式还有待提升。因此，提出了本申请提供的可以提升控制便利性以及智能化的视频增强控制方法、装置、电子设备及存储介质。
下面将结合具体实施例对本申请内容进行介绍。
请参阅图2，本申请提供的一种视频增强控制方法，应用于电子设备，所述方法包括：
步骤S110：当检测到处于视频播放状态后，获取所播放视频对应的分辨率。
在本申请中，电子设备可以通过多种的方式来识别当前是否处于视频播放状态。
作为一种方式，所述检测电子设备是否处于视频播放状态的步骤包括：检测所述电子设备中是否有设定的视频播放应用程序在运行；若检测到有设定的视频播放应用程序在运行，判定所述电子设备处于所述视频播放状态。其中，电子设备可以预先建立一个视频播放应用程序的名单，以便在该名单中记录视频播放应用程序。其中，该名单可以由电子设备的用户自由配置，也可以根据某个视频播放应用程序的使用情况来确定。
例如，如图3所示，在图3所示的界面中显示有多个应用程序，以及每个应用程序对应的状态。可以理解的是，若应用程序对应的状态为图示的“关”，那么表示该应用程序移除或者不加入到上述名单中，若应用程序对应的状态为图示的“开”，那么表示该应用程序加入到上述名单中。例如，对于名称为“TX视频”的应用程序，其对应的状态为“开”，即表示“TX视频”这个应用程序会存在于前述的名单中。而对于名称为“AQY视频”的应用程序，其对应的状态为“关”，那么表示“AQY视频”这个应用程序不会存在于前述的名单中。
再者，电子设备可以检测每个视频播放应用程序的使用频率，若检测到某个视频播放程序的使用频率超过设定的频率，则可以将该视频播放应用程序添加到前述名单中，并对应的将该视频播放应用程序的名称在图3中所对应的状态配置为“开”。
那么在这种情况下，电子设备可以先检测当前在前台运行的应用程序是哪个，然后再进一步的检测当前前台运行的应用程序是否在该名单中，若在，那么就判定当前处于视频播放状态。其中，作为一种方式，若电子设备为Android操作系统，可以通过执行ActivityManager的getRunningTasks方法来获取到当前在前台运行的应用程序的名称。此外，电子设备还可以通过UsageStatsManager来获取用户使用的应用程序的列表，将该列表中记录的最近使用的应用程序识别为当前的前台应用。再者，还可以通过Android自带无障碍功能，监控窗口焦点的变化，拿到焦点窗口对应包名作为当前在前台运行的应用程序。
作为另外一种方式，电子设备还可以结合检测AudioManager类的返回值来确定是否有视频在进行播放。在这种情况下，电子设备可以先检测AudioManager类的返回值来确定是否有音频输出，若在检测到有音频输出的情况下，再进一步的根据前述检测是否有视频播放应用程序运行来确定电子设备是否处于视频播放状态。
再者，作为再一种方式，电子设备还可以通过检测视频播放按键的触控状态来检测是否处于视频播放状态。例如，如图4所示，在图4所示的视频播放界面99中显示有播放按键98，且图4中所示的界面为视频播放暂停的状态。那么在这种情况下，当检测到播放按键98被触控后，即可判定电子设备当前处于视频播放状态。
在本申请中，电子设备有多种方式可以获取到所播放视频的分辨率。作为一种方式，电子设备可以通过对所播放的视频的画面进行图像识别的方式获取到所播放视频的分辨率。例如，电子设备可以从所播放的视频中获取一帧图像，然后对该图像进行识别，进而获取到该一帧图像的分辨率，将该分辨率作为当前所播放视频的分辨率。
再者，通常所播放的视频可以分成多个部分。例如，对于一些网络视频通常包括广告部分以及视频内容部分。而其中的视频内容部分为表征视频所要表达的内容的部分。例如，对于一些电视剧类型的视频，电视剧类型的视频通常在前面部分会包括有片头广告。那么如果电子设备在采集某一帧图像时所采集到的为片头广告部分，那么就会造成所获取的图像与视频内容部分无关，进而无法准确获取到所播放视频的分辨率。
那么作为一种方式，电子设备可以在检测到处于视频播放状态以后，根据所播放视频的时长长度，直接获取所播放视频的中间部分的一帧图像。其中，该中间部分为整个视频时间长度中间的部分。例如，如果所播放视频的整个时间长度为60分钟，那么中间部分为第30分钟的部分。而作为另外一种方式，如果所播放的视频是可以识别片头以及视频内容部分的，那么电子设备可以在检测到播放视频内容部分的过程中获取某一帧图像来检测分辨率。
而作为再一种方式，电子设备可以在检测到当前所播放的视频已经播放指定时长后，获取该指定时长以后的视频内容中的某一帧图像来检测分辨率。可以理解的是，视频的片头广告通常会在60秒到80秒，那么电子设备可以 根据统计得到的片头广告的时长来作为指定时长。
此外，电子设备除了可以通过直接检测所播放的视频来获取分辨码率外，还可以通过分辨率选择控件来获取。可以理解的是，在所播放的视频支持多种等级分辨率的情况下，用户可以操作分辨率选择控件来选择自己需要的分辨率。例如，在播放的视频支持超清、高清以及标清的情况下，用户可以通过分辨率选择控件选择视频以超清的分辨率进行播放，那么在用户选择了超清以后，电子设备可以在本地存储该选择的结果，那么电子设备可以通过读取该选择的结果，来确定当前所播放视频的分辨率，即将与用户所选择的分辨率选择控件对应的分辨率确定为当前所播放视频对应的分辨率。
作为一种方式，视频的清晰度通常可以分成多个等级。例如，蓝光、超清、高清等。而不同的视频制作者对于视频的等级的分级方式可能不同。或者是由于设置错误，会造成视频所对应的分辨率不是该视频实际的分辨率。例如，某个视频的实际分辨率为高清，而由于配置错误会造成给该视频分配的分辨率为超清，进而造成视频的配置分辨率与实际分辨率不同。那么在这种情况下，即使用户选择了超清，而电子设备在播放视频的过程中，所播放视频的实际分辨率为高清，从而会造成电子设备在获取所播放的视频的分辨率的过程中，获取到错误的分辨率。
那么作为一种方式，可以在获取所播放的视频的分辨率的过程中，既直接通过检测所播放的视频的某一帧图像的分辨率来作为第一待对比分辨率，而也获取存储在本地的表征用户所选择的分辨率的结果来作为第二待对比分辨率，进而将该第一待对比分辨率与第二待对比分辨率进行比对，在比对第一待对比分辨率和第二待对比分辨率相同的情况下，将第一待对比分辨率和第二待对比分辨率中的任意一个作为所播放视频对应的分辨率。而在第一待对比分辨率和第二待对比分辨率不相同的情况下，将第一待对比分辨率作为所播放视频对应的分辨率。
步骤S120：判断网络状态是否满足所述分辨率对应的播放条件。
可以理解的是，视频通常是由多帧图像组成的。而对于图像，不同的分辨率所对应的数据量是不同的。而不同的数据量，所需要的传输网络带宽是不同的。例如，对于蓝光、超清以及高清所要求的网络带宽依次降低。那么作为一种方式，可以通过网络带宽来表征网络状态。那么在这种情况下，电子设备在确定了所播放视频的分辨率的情况下，基于可以获取到所播放视频的分辨率的播放条件，其中该播放条件包括该所播放视频对应的传输速率。其中，该传输速率为顺利传输该分辨率的视频的最低网络数据传输速率。
作为一种方式，对于某一种分辨率对应的传输速率可以预先配置后存储在电子设备中，从而便于电子设备在获取到所播放视频的分辨率以后，可以从本地获取到所播放视频的分辨率对应的传输速率。
那么在这种情况下，电子设备可以获取当前所接入网络的传输速率，然后将该当前所接入网络的传输速率与所播放视频的分辨率对应的传输速率进行比对，若当前所接入网络的传输速率不小于所播放视频的分辨率对应的传输速率，那么就判定网络状态满足所述分辨率对应的播放条件，若当前所接 入网络的传输速率小于所播放视频的分辨率对应的传输速率，那么就判定网络状态不满足所述分辨率对应的播放条件。
步骤S130：若所述网络状态不满足所述播放条件，降低所述所播放视频的分辨率，对所播放的视频进行视频增强，所述视频增强包括对所播放视频的图像进行增强。
作为一种方式，可以通过对所播放视频的图像参数进行调节，以增强所述图像进行增强。
其中，图像参数包括清晰度调节参数、镜头畸变控制参数、色域控制参数、色彩调节参数、锐度调节参数、亮度调节参数、对比度调节参数、降噪控制参数以及饱和度调节参数中的至少一个。其中，作为一种方式，可以根据降低分辨率的程度来确定所要调节的图像参数。例如，若降低分辨率的程度较大，那么可以更多的参数。可选的，若将分辨率由超清降低到标清，那么电子设备可以调节所播放视频的清晰度调节参数、锐度调节参数、亮度调节参数等，而若电子设备是将分辨率由超清降低到高清，那么电子设备可以配置调节所播放视频的清晰度调节参数。
步骤S140：若所述网络状态满足所述播放条件，以当前的分辨率播放视频。
本申请提供的一种视频增强控制方法，在当检测到处于视频播放状态后，获取所播放视频对应的分辨率，并判断网络状态是否满足所述分辨率对应的播放条件，若所述网络状态不满足所述播放条件，降低所述所播放视频的分辨率，对所播放的视频进行视频增强。本方法通过在检测到当前的网络状态不满足所播放的视频的分辨率的情况下，降低当前所播放视频的分辨率，进而以适应当前的网络状态，并且同时开启视频增强，从而使得在网络不支持当前分辨率的情况下，依然可以使得所播放的视频可以有较高的播放视效，提升了用户体验。
请参阅图5，本申请提供的一种视频增强控制方法，应用于电子设备，所述方法包括：
步骤S210：当检测到处于视频播放状态后，获取所播放视频对应的分辨率。
步骤S220：判断网络状态是否满足所述分辨率对应的播放条件。
步骤S230：若所述网络状态不满足所述播放条件，降低所述所播放视频的分辨率，对所播放的视频进行视频增强。
步骤S231：若所述网络状态满足所述播放条件，以当前的分辨率播放视频。
步骤S240：判断网络状态是否满足所述分辨率对应的播放条件。
电子设备在执行步骤S230以后，依然会定时检查当前的网络状态，而在检测到当前的网络状态满足所述播放条件以后，就可以提升所播放视频的分辨率。
步骤S250：若判定当前的网络状态满足所述播放条件，提升所述所播放视频的分辨率。
作为一种方式，若判定当前的网络状态满足所述播放条件，提升所述所播放视频的分辨率到目标分辨率。
而对于目标分辨率，电子设备可以有多种方式来确定。可选的，电子设备可以随机提升到相对之前降低后的分辨率更高的分辨率。可选的，电子设备可以将分辨率提升到之前用户所选择的分辨率。可以理解的是，用户在视频开始播放之前或者在视频播放过程中选择自己所需要的分辨率，那么在电子设备判断网络状态不支持用户所选择的分辨率的播放条件以后，电子设备可以降低用户所选择的分辨率，那么当电子设备检测到当前的网络支持用户所选择的分辨率的播放条件以后，电子设备可以将所播放的视频的分辨率切换到用户所选择的分辨率。
例如，若用户选择的分辨率为超清，而电子设备检测到当前的网络状态并不满足超清的播放条件，那么可以将分辨率降低到高清进行播放。而当电子设备检测到当前的网络状态满足超清的播放条件以后，可以将视频的分辨率从高清提升到超清。
作为一种方式，所述若判定当前的网络状态满足所述播放条件，提升所述所播放视频的分辨率的步骤之后还包括：停止对所述所播放的视频进行视频增强。
可以理解的是，在对视频进行视频增强以后，可以在一定程度上提升所播放视频的视觉效果。例如，作为一种增强方式，电子设备可以对所播放的视频进行锐化，进而提升所播放视频的清晰度。而作为另外一种增强方式，电子设备可以对所播放的视频的饱和度进行增强，进而使得所播放的视频的颜色更加的饱满。而在一些场景下，用户是可以感知视频增强的启动以及停止的，那么作为一种方式，所述停止对所述所播放的视频进行视频增强的步骤包括：获取视频画面的参数；基于所述参数确定关闭视频增强的时刻；在所述时刻开始关闭对所述所播放的视频进行视频增强。
可选的，所述基于所述参数确定关闭视频增强的时刻的步骤包括：判断视频画面的亮度是否低于指定亮度；若判定视频画面的亮度低于指定亮度，将检测到视频画面的亮度低于指定亮度的时刻作为关闭视频增强的时刻。
可选的，所述若判定视频画面的亮度低于指定亮度，将检测到视频画面的亮度低于指定亮度的时刻作为关闭视频增强的时刻的步骤包括：若判定视频画面的亮度低于指定亮度，获取检测到视频画面的亮度低于指定亮度的时刻之后的多帧视频画面；基于所述多帧视频画面的亮度，计算亮度低于所述指定亮度的持续时间长度；若判定所述时间长度大于指定长度，将检测到视频画面的亮度低于指定亮度的时刻作为关闭视频增强的时刻。
可以理解的是，当视频画面的亮度低于指定亮度的情况下，用户对于视频画面的内容识别度相较于视频画面的亮度高于指定亮度的情况下更差。例如，当视频画面所显示的内容是在白天，那么对于视频画面是否清晰，用户感知较为敏感，而当视频画面所显示的内容是在夜晚，那么用户对于视频的清晰度是否清晰感知较差。那么在这种情况下，若在将检测到视频画面的亮度低于指定亮度的时刻作为关闭视频增强的时刻，可以在进行视频增强关闭 时，减小用户识别的概率，进而使得可以在用户无感知或者感知较小的情况下，完成视频增强的关闭，以提升用户体验。
本申请提供的一种视频增强控制方法，在当检测到处于视频播放状态后，获取所播放视频对应的分辨率，并判断网络状态是否满足所述分辨率对应的播放条件，若所述网络状态不满足所述播放条件，降低所述所播放视频的分辨率，对所播放的视频进行视频增强。而当在检测到网络又满足播放条件以后，开始提升所述所播放视频的分辨率，并根据分辨率的提升，降低视频增强效果，进而降低功耗。本方法通过在检测到当前的网络状态不满足所播放的视频的分辨率的情况下，降低当前所播放视频的分辨率，进而以适应当前的网络状态，并且同时开启视频增强，从而使得在网络不支持当前分辨率的情况下，依然可以使得所播放的视频可以有较高的播放视效，提升了用户体验。
请参阅图6，本申请提供的一种视频增强控制方法，应用于电子设备，所述方法包括：
步骤S310：当检测到处于视频播放状态后，获取所播放视频对应的分辨率。

步骤S330：若所述网络状态不满足所述播放条件，降低所述所播放视频的分辨率。

步骤S340：基于所降低的分辨率的幅度，确定视频增强的效果，其中，分辨率降低幅度越大，确定的增强效果越强。
可以理解的是，分辨率越高的视频对应的视频效果越好。那么在分辨率降低幅度较大的情况下，所呈现的视频效果就越差，那么在这种情况下，就需要更大程度的视频增强效果，来保证视频较高的视觉体验。例如，在用户选择的分辨率为超清的情况下，将超清的分辨率降低到标清所对应的视频增强幅度，会大于在将超清降低到高清所对应的视频增强幅度，进而所对应的增强效果越强。
步骤S350：基于所述确定的视频增强效果进行视频增强。
