/usr/bin/time -v /usr/bin/vlc --play-and-exit video.webm
/usr/bin/time -v /usr/bin/snap run vlc --play-and-exit video.webm

VLC perf command

/usr/bin/perf record /usr/bin/vlc-wrapper --play-and-exit video.webm
/usr/bin/perf report

GIMP 10-loop scripts

#!/bin/bash
for i in `seq 1 10`;
do
    /bin/cp template.jpg file.jpg
    sync
    sleep 1
        /usr/bin/gimp -i -b '(simple-unsharp-mask "file.jpg" 5.0 0.5 0)' -b '(gimp-quit 0)'
        sleep 1
done    
exit 0

#!/bin/bash
for i in `seq 1 10`;
do
    /bin/cp template.jpg file.jpg
    sync
    sleep 1
        /usr/bin/snap run gimp -i -b '(simple-unsharp-mask "file.jpg" 5.0 0.5 0)' -b '(gimp-quit 0)'
        sleep 1
done    
exit 0

GIMP simple-sharpen-mask.scm script

(define (simple-unsharp-mask filename radius amount threshold)
(let* ((image (car (gimp-file-load RUN-NONINTERACTIVE filename filename)))
(drawable (car (gimp-image-get-active-layer image))))
(plug-in-unsharp-mask RUN-NONINTERACTIVE image drawable radius amount threshold)
(gimp-file-save RUN-NONINTERACTIVE image drawable filename filename)
(gimp-image-delete image)))

The script needs to be placed under:

• Repository package: ./.gimp-2.8/scripts/
• Snap package: ~/snap/gimp/current/.config/GIMP/2.10/scripts/

/usr/bin/time -v /usr/bin/gimp -i -b '(simple-unsharp-mask "file.jpg" 5.0 0.5 0)' -b '(gimp-quit 0)'
/usr/bin/time -v /usr/bin/snap run gimp -i -b '(simple-unsharp-mask "file.jpg" 5.0 0.5 0)' -b '(gimp-quit 0)'

GIMP perf command

/usr/bin/perf record /usr/bin/gimp -i -b '(simple-unsharp-mask "file.jpg" 5.0 0.5 0)' -b '(gimp-quit 0)'
/usr/bin/perf record /usr/bin/snap run gimp -i -b '(simple-unsharp-mask "file.jpg" 5.0 0.5 0)' -b '(gimp-quit 0)'
