2、 operating instructions
2.1 Obtain the video stream log GPSMediaSvr of the device - - - - libmdvrnet

The timestamp interval between two consecutive frames reported by the 2.2 device is wrong
The timestamp unit is microseconds, 1 second = 1000 milliseconds = 1000000 microseconds
Normally, 25 frames of data are reported in 1 second, and each frame interval is 0.04 seconds = 40 milliseconds = 40000 microseconds.
The timestamp interval of the above screenshots is 1430414- 1430374=40 (microseconds), which should normally be 40000 microseconds apart, thus causing the video to be played fast forward.
