[FFmpeg-user] Make thumbnail each segment of video

[aradeonas]

Hi, 

I Have two command one for segmenting video : 

> ffmpeg -i vid.mp4 -acodec copy -f segment -vcodec copy -reset_timestamps 1  
> t .\OUTPUT%d.mp4
And one for make thumbnail for each OUTPUT%d.mp4 file : 

> for %%i in (*.mp4) do ffmpeg -i "%%i" -vf scale='min(150,iw)':-1 -f image2  
> -vframes 1 "%%~ni.jpg"
But how can I just extract thumbnail from vid.mp4 ? 

Please consider I don't want thumbnail from for example each 5 second,first  
command result make segmnet with various durations and I just want their  
thumbnail not result videos. 

I hope its clear. 

Regards, 

Ara
