c++ opencv的：

https://github.com/Lakshya-Kejriwal/Real-Time-Video-Stabilization

c的，需要自己编译，需要ffmpeg，能处理视频

https://github.com/georgmartius/vid.stab

Using default values:

ffmpeg -i input.mp4 -vf vidstabtransform,unsharp=5:5:0.8:3:3:0.4 out_stabilized.mp4
 

Note the use of the ffmpeg's unsharp filter which is always recommended.

Zooming-in a bit more and load transform data from a given file:

ffmpeg -i input.mp4 -vf vidstabtransform=zoom=5:input="mytransforms.trf" out_stabilized.mp4
 

Smoothening the video even more:

ffmpeg -i input.mp4 -vf vidstabtransform=smoothing=30:input="mytransforms.trf" out_stabilized.mp4
