Requires {{deb|ffmpegthumbnailer}}: |
|||
<source lang="bash"> |
|||
THUMBDIR=thumbnails |
|||
THUMBSUMMARY=summary.png |
|||
make_thumbnails() |
|||
{ |
|||
if [ -d $THUMBDIR ]; then |
|||
mv $THUMBDIR $THUMBDIR-$(date +"%Y%m%d%H%M%S") |
|||
fi |
|||
# sudo apt install ffmpegthumbnailer |
|||
SIZE=512 |
|||
mkdir -p "$THUMBDIR" |
|||
i=0 |
|||
for f in *; do |
|||
[ "$f" = "$THUMBDIR" ] && continue |
|||
echo -- "$f" |
|||
ffmpegthumbnailer -s $SIZE -i "$f" -o "$THUMBDIR/$f-10.png" -c png -t 10 |
|||
ffmpegthumbnailer -s $SIZE -i "$f" -o "$THUMBDIR/$f-20.png" -c png -t 20 |
|||
((i++)) |
|||
# [ $i -lt 5 ] || break |
|||
done |
|||
echo "Doing montage..." |
|||
montage -label %f -frame 5 -geometry "$SIZEx$SIZE+2+2>" $THUMBDIR/*.png $THUMBSUMMARY |
|||
mv $THUMBSUMMARY $THUMBDIR/ |
|||
} |
|||
</source> |
|||
Note that the thumbnail summary can be quite big. Use viewer like {{deb|feh}} to view it. The same application can be used to view thumbnails easily: |
|||
<source lang="bash"> |
|||
THUMBDIR=thumbnails |
|||
THUMBSUMMARY=summary.png |
|||
view_thumbnails() |
|||
{ |
|||
# sudo apt intall feh |
|||
feh -dF --zoom fill $THUMBDIR |
|||
} |
|||
view_thumbnails_summary() |
|||
{ |
|||
# sudo apt intall feh |
|||
feh $THUMBDIR/$THUMBSUMMARY |
|||
} |
|||
</source> |
|||
| ⚫ | |||
<source lang="bash"> |
|||
ffmpeg -itsoffset -5 -i "$srcimg" -vcodec mjpeg -vframes 1 -an -f rawvideo -s 200x200 -loglevel quiet "$dest" |
