Specify a directory, this script will search it to find all MP4 videos, convert them to JPGs at a desired FPS and resize them to a given size.
Download and chmod +x generateFrames.sh to make it executable. Now use as follows:
Example 1: Create 5 images every second of video (ie every 200ms):
./generateFrames.sh /home/user/directoryOfVideos 5
Example 2: Can also optionally pass scale as 3rd parameter
./generateFrames.sh /home/user/directoryOfVideos 5 320:-1
In this case it would resize the width to be 320px and keep aspect ratio for height.
