### Function Description

Data frame header definition.

### Member Description

Member | Type | Remark
--- | --- | ---
deviceID | unsigned int | Device ID number, used by SDK to distinguish devices.
channel | unsigned int | Channel number.
frameType | unsigned int | See `DD_FRAME_TYPE`.
length | unsigned int | Frame data length.
keyFrame | unsigned int | 0: non-keyframe 1: keyframe.
width | unsigned int | Data frame width.
height | unsigned int | Data frame height.
frameIndex | unsigned int | Dataframe index.
frameAttrib | unsigned int | Data frame attributes, see `DD_FRAME_ATTRIB`.
streamID | unsigned int | Data stream ID number.
time | LONGLONG | Absolute time, the absolute time starting from 0:0:0:0 on January 1, 1970, in microseconds, will change when the device time is changed.
relativeTime | LONGLONG | Relative time, in microseconds, does not change when the device time is changed and is a continuous time.
