技术领域

本实施例的执行主体为安装在终端的客户端，例如可以是短视频应用程序或音乐播放软件等。终端可以为移动终端(例如，智能手机、平板电脑等)，也可以为固定终端(例如，台式电脑)。
其中，多媒体可以为视频，相应的文字为台词；也可以为音乐，相应的文字为歌词。
其中，显示特效可以为将文字进行放大、缩小、逐渐从终端屏幕消失、逐渐显示在终端屏幕等。
具体的，可以在客户端应用界面提供多媒体选项和/或文字特效资源选项，例如，提供多媒体列表，其中多媒体列表中包含多个多媒体名称，例如视频名称或音乐名称；和/或文字特效资源列表，其中，文字特效资源列表中包含特效信息，例如放大或缩小等。通过上述多媒体选项和/或文字特效资源选项，用户可以根据需求在客户端选择多媒体和/或对应的文字特效资源，然后从本地获取对应的多媒体及与多媒体相关联的文字，或者，向服务器发送获取多媒体资源的请求， 接收服务端发送的多媒体和与多媒体相关联的文字，例如音乐及对应的歌词。
步骤S12：接收所述服务器发送的所述文字特效资源。
其中，所述服务器可以为第三方服务器，该第三方服务器主要用于存储文字特效资源。也可以为与客户端对应的应用服务器，该应用服务器除了用于存储文字特效资源之前，还用于存储多媒体及与所述多媒体相关联的文字。
步骤S13：根据所述文字特效资源对所述文字进行特效处理，使得所述文字跟随所述多媒体的播放进度显示在终端屏幕上，并逐渐从所述终端屏幕上消失。
具体的，以所述多媒体为音乐和歌词为例，根据服务器发送的文字特效资源对歌词进行特效处理，在音乐播放的过程中，使歌词随着音乐的播放在终端屏幕上由显示逐渐消失。
本实施例通过向服务器获取文字特效资源，根据所述文字特效资源对所述文字进行特效处理，使得所述文字跟随所述多媒体的播放进度显示在终端屏幕上，并逐渐从所述终端屏幕上消失，无需对客户端进行更新，就可以获取到文字特效资源，使文字特效使用起来更加灵活。
在一个可选的实施例中，步骤S13具体包括：
步骤S131：获取所述多媒体的播放进度对应的时间戳和所述时间戳对应的文字。
其中，时间戳为当前播放时间相对于起始播放时间的时间长度。

步骤S132：根据所述时间戳确定所述时间戳对应的文字的显示透明度。
其中，显示透明度可以为0-1之间的值，当显示透明度由0变为1时，则逐渐显示所述文字，当显示透明度由1变为0时，则所述文字逐渐消失。具体值根据时间戳实时确定。
步骤S133：根据所述显示透明度对所述时间戳对应的文字进行特效处理，使得所述文字跟随所述多媒体的播放进度显示在终端屏幕上，并逐渐从所述终端屏幕上消失。
具体的，根据显示透明度对多媒体的播放过程中的每一时间戳对应的文字进行特效处理，可以使得所述文字跟随所述多媒体的播放进度显示在终端屏幕上，并逐渐从所述终端屏幕上消失。
在一个可选的实施例中，所述方法还包括：
步骤S14：根据所述终端的分辨率生成位移图；其中，所述位移图中包含每个像素点的初始位移；
例如，如果终端屏幕分辨率为720*1280，则生成720*1280大小的位移图。
相应的，步骤S133具体包括：
步骤S1331：根据所述时间戳确定播放百分比；其中，所述播放百分比为所述文字的当前播放进度占总进度的比例。
步骤S1332：根据所述播放百分比和所述初始位移确定目标位移。
其中，目标位移可以为播放百分比与所述初始位移的乘积。
步骤S1333：根据所述显示透明度和所述目标位移对所述时间戳对应的文字进行特效处理，使得所述文字跟随所述多媒体的播放进度显示在终端屏幕上，并逐渐从所述终端屏幕上消失。
具体的，采用显示透明度乘以由所述文字组成的图像中的每个像素点的像素值，作为所述目标位移对应的像素点的像素值，随着播放进度显示透明度实时改变，即由1逐渐变化为0，使得文字跟随所述多媒体的播放进度显示在终端屏幕上，并逐渐从所述终端屏幕上消失。
在一个可选的实施例中，步骤S14具体包括：
步骤S141：根据所述终端的分辨率生成模板图片；其中，所述模板图片中包含n个特征点；其中，n为正整数；

其中，文字特效资源中包含排版参数。
其中，排版参数包含字体、字号、字形、颜色、阴影和下划线等。
其中，位图是由组成文字的像素组成的，像素是位图最小的信息单元，存储在图像栅格中。每个像素都具有特定的位置和颜色值。按从左到右、从上到下的顺序来记录文字中每一个像素的信息，例如：像素在终端屏幕上的位置、像素的颜色等。
步骤S1335：根据所述显示透明度确定所述位图中的每个像素点的像素值。
例如，将显示透明度乘以由所述文字组成的图像中的每个像素点的初始像素值得到位图中的每个像素点的像素值。
步骤S1336：在所述终端的屏幕上显示所述文字，并将所述每个像素点沿所述目标位移移动，并跟随所述多媒体的播放进度由显示逐 渐消失。
具体的，在渲染时，获取每个像素点的所述目标位移，在OpenGL(Open Graphics Library，开放图形库)中渲染，以便加速性能。
