I have ffmpeg command line that creates thumbnail image from a video. This works nicely as I can choose the timestamp and the size of the image that I want.
-r 1 -t 1 -ss 2 -s cga "%2/%32.jpg"
This option in the command creates the image.
Now I am moving to use HandbrakeCLI for conversion. But I am stuck with this thumbnail generation.
How do I achieve this with HandbrakeCLI so that when I am converting video to MP$, I also generate one\more thumbnails of a given size and timestamp?
