A simple Bash script to capture screenshots from 100th seconds and 100th seconds from the end of the video for submitting the claim.
This script uses FFMpeg to generate the screenshots. Run apt install ffmpeg if your computer hasn't had one yet.
./screenshot.sh -f <input_file> -p <prefix>
./screenshot.sh -f zoom_0.mp4 -p 20210819
./screenshot.sh -f "Path with space/zoom_0.mp4" -p 20210819
The above command will write 20210819_screenshot_start.jpg and 20210819_screenshot_end.jpg in the current working directory.
