## Detailed Description
该QVideoFrame类提供的视频数据的帧的表示。
一个QVideoFrame封装了一个视频帧,以及有关帧信息的数据。
一视频帧的内容可以通过使用被映射到存储器中的[map](qvideoframe.html#map)()函数。而映射到的视频数据可以使用访问[bits](qvideoframe.html#bits)()函数返回一个指向缓冲区的指针,它的总的大小是由给定的[mappedBytes](qvideoframe.html#mappedBytes)()和每一行的大小由下式给出[bytesPerLine](qvideoframe.html#bytesPerLine)( ) 。的返回值[handle](qvideoframe.html#handle)()函数可用于使用内部缓冲器的本机API来访问帧数据。
在一个QVideoFrame视频数据被封装在一个[QAbstractVideoBuffer](qabstractvideobuffer.html)。一个QVideoFrame可以从任何缓冲类型的子类的构造[QAbstractVideoBuffer](qabstractvideobuffer.html)类。
**Note:**QVideoFrame是公开共享的,以视频帧所做的任何更改也将适用于任何副本。
