上述步骤 401和步骤 402是对每一帧所进行的处理, 各帧的处理操作相同, 重复执行, 并将每帧逐一记录至文件中, 直至音视频内容录制结束。
本发明实施例与上述实施例二的区别在于:本发明实施例中所述各类涂鸦 输入并没有合成当前帧的涂鸦图片,而是分别记录至涂鸦文件且在涂鸦信息维 护表中分别记录各类涂鸦输入的属性信息,这样在单独更改各类所述涂鸦输入 时可以只更新其对应的属性信息,从而在效率上有所提升。例如在擦除触摸轨 迹输入或切换触摸轨迹输入的线宽和颜色等属性信息时只更新所述涂鸦信息 维护表中触摸轨迹输入的属性信息;而删除或增加附加图片时则只更新所述涂 鸦信息维护表中附加图片的属性信息, 方便用户单独对各类涂鸦输入进行操 作。

步骤 501、 获取当前帧的音视频内容, 存储至音视频帧緩存中。
具体地, 可以通过摄像机和麦克风釆集音视频内容,在视频回显时会把音 视频数据存放在音视频帧緩存中, 而所述音视频帧緩存为硬件资源,存在于所 有的移动终端设备中。
步骤 502、 在获取当前帧音视频内容的同时, 在透明背景层中釆集至少一 种类别的涂鸦输入, 将各类涂鸦输入分别存储至各类涂鸦帧緩存中。 具体地, 所述各类所述涂鸦输入至少包括: 触摸轨迹输入和附加图片, 例 如,还包括透明背景图片; 所述各类涂鸦输入在回显时会把涂鸦数据存放于所 述各类涂鸦帧緩存中, 例如, 所述触摸轨迹输入在回显时会把触摸形成的图形 数据存放于触摸显示帧緩存中, 而附加图片等存放在用户界面显示帧緩存中。
步骤 503、 将当前帧的音视频帧緩存和各类涂鸦帧緩存的数据合成, 并存 储至合成帧緩存中。
具体地, 通过图层 (或音频) 混合器 (mixer )将当前帧的音视频帧緩存 的图层数据和各类涂鸦帧緩存的图层数据合成一个主图层的数据,合成后的数 据是最后送入显示设备的数据。例如,每个图层的数据都是 ARGB32的格式的, 由于最后的显示是一个主图层, 而此主图层是按照多个图层的组合而成的, 这 个组合方式具体是指由一个对应的控制数据说明每个区域对应的图层的数据, 混合器根据这个信息将各个图层数据做与 /或合成。
步骤 504、 将合成帧緩存中的数据进行编码, 形成当前帧的音视频, 并记 录至涂鸦视频文件。
具体地, 所述编码, 即压缩编码标准, 以减少传输的流量, 例如釆用 H.264/MPEG4标准。
步骤 505、 重复执行步骤 501至步骤 504对各帧进行处理, 直至判断出音视 频内容的录制结束。
上述步骤 501至步骤 504是对每一帧所进行的处理, 各帧的处理操作相同, 重复执行,并将每帧逐一记录至涂鸦视频文件中 ,直至音视频内容的录制结束。
本发明实施例,将当前帧的音视频内容和各类涂鸦输入通过硬件混合器合 成,在播放解析时不用分别解析处理音视频内容和涂鸦输入, 由此节省接收方 的解析时间, 提升播放效率。

实施例六
图 7为本发明实施例六提供的视频短信的接收方法流程图, 本实施例在上 述实施例的基础上对从所述视频短信中解析获取音视频内容和涂鸦输入,并将 所述涂鸦输入叠加在所述音视频内容上播放进行进一步优化, 如图 7所示, 从 所述视频短信中解析获取音视频内容和涂鸦输入,并将所述涂鸦输入叠加在所 述音视频内容上播放可以包括:
步骤 701、 从所述视频短信的涂鸦视频文件中标记的音视频文件和涂鸦文 件各自的起始位置分别解析获取音视频文件和涂鸦文件;
具体地,所述涂鸦视频文件中所述音视频文件和涂鸦文件只是简单的头尾 相连, 并且所述涂鸦视频文件中包含有一个文件头,记录叠加后两个文件的起 始位置, 便于解析文件时拆分两个文件。
步骤 702、 从所述音视频文件中分流获取音频层和视频层;
具体地, 所述音频层可以为通过麦克风釆集的声音数据; 所述视频层可以 为通过摄像头釆集的视频数据。
步骤 703、 从所述涂鸦文件中获取涂鸦层;
具体地, 所述涂鸦层可以为通过触摸屏釆集的触摸轨迹输入、 附加图片或 透明背景图片等图像信息所合成的涂鸦图片。
步骤 704、根据涂鸦文件中的涂鸦信息维护表记录的涂鸦图片的属性信息, 将所述涂鸦层与所述音频层和视频层进行帧时间同步;
具体地, 所述涂鸦信息维护表中主要是每一帧涂鸦图片的大小、 时间点、 编码格式和持续时间等属性信息。根据所述涂鸦图片的时间点和持续时间与所 述音频层和视频层进行帧时间同步。
步骤 705、 将所述音频层通过音频通道播放, 将视频层通过视频通道的第 二层播放, 将所述涂鸦层通过视频通道的第一层播放, 所述第一层叠加在所述 第二层之上。
具体地, 由于所述涂鸦层中的涂鸦文件存储的是将涂鸦输入, 例如透明背 景图片、 触摸轨迹输入和附加图片等信息, 合成之后的涂鸦图片, 所以, 所述 涂鸦层的播放与视频层播放一样, 直接送去视频通道显示即可。 另外, 由于涂 鸦输入是在当前帧视频内容上的添加的,所以,涂鸦层叠加在视频层之上播放。
本发明实施例中每帧涂鸦图片都是与当前帧音视频内容同步合成的 ,可以 节省帧同步时间;所述涂鸦文件的涂鸦信息维护表中记录当前帧涂鸦图片的属 性信息以便于解析, 另外, 该技术方案可以解析获得独立的音视频文件和涂鸦 文件, 用户可以在涂鸦视频的基础上进行二次修改或二次涂鸦, 方便用户随时 编辑涂鸦视频。

具体地, 所述涂鸦层可以为通过触摸屏釆集的触摸轨迹输入和 /或附加图 片。
步骤 804、 根据涂鸦文件中的涂鸦信息维护表记录的各类涂鸦输入的属性 信息, 将所述涂鸦层中各类涂鸦输入与所述音频层和视频层进行帧时间同步; 具体地, 所述各类涂鸦输入至少包括: 触摸轨迹输入和附加图片。 其中, 所述触摸轨迹输入的属性信息可以是触摸轨迹坐标、 线宽、 颜色、 时间点和持 续时间等, 所述附加图片的属性信息可以是图片大小、 时间点和持续时间等。 可以根据所述触摸轨迹输入和附加图片的对应的时间点和持续时间与所述音 频层和视频层进行帧时间同步。
步骤 805、 将所述音频层通过音频通道播放, 将视频层通过视频通道的第 二层播放, 将所述涂鸦层中各类涂鸦输入分别通过视频通道的第一层播放, 所 述第一层叠加在所述第二层之上。
具体地, 由于所述涂鸦层中的涂鸦文件存储的是各类涂鸦输入, 例如触摸 轨迹输入和附加图片等信息, 所以, 所述涂鸦层的播放与视频层播放至少分两 种情况: 若是所述附加图片, 则直接送去视频通道的第一层显示即可; 若是所 述触摸轨迹输入, 则根据触摸轨迹坐标、线宽和颜色等信息绘制至视频通道的 第一层。 另外, 由于涂鸦输入是在当前帧视频内容上的添加的, 所以, 涂鸦层 叠加在视频层之上播放。
本发明实施例中各类所述涂鸦输入的属性信息在涂鸦信息维护表中单独 记录, 可以解析获得独立的各类涂鸦输入, 方便用户随时编辑涂鸦视频, 而且 用户在涂鸦视频上分别对各类涂鸦输入进行二次操作时, 例如修改或再涂鸦, 只需在原涂鸦视频基础上对所述各类涂鸦输入分别相应更新,无需再将各类涂 鸦输入合成当前帧的涂鸦图片去替换原先的涂鸦图片, 使得二次操作更方便、 快捷。
