To handle this there is a 16-bitframe type field in the Ethernet header.
以太帧头中有个16比特的帧类型区域控制此项。

Contributing to the file size, in order of importance, are the parameters that set the video bit rate, audio sample frequency, audio bit rate, then frame size.
对文件大小的贡献，按重要性的顺序，依次是视频比特率、音频采样频率、音频比特率，然后是帧速。
