I purchased the A119 with gps recently and installed it without any problems.
After checking some of the footage found I had terrible video shake while driving on smooth roads.
I originally thought it was the camera moving up and down between the gps and dvr as it is a loose fitting but...
Hey everyone, this is my tutorial how to stabilize the recorded video.
STEP BY STEP:
Download and unzip ffmpeg from https://ffmpeg.org/download.html
Extract the 7zip archive (I recommend extract it to root of any partition e.g. C:\ or D:\)
Rename the folder to „ffmpeg“
