raspistill annotation timestamp not updating

Question

When doing a timelapse, the annotation only shows the initial timestamp, not the current timestamp of each frame - which makes imho no sense? Am I doing something wrong? Is there any quick workaround?

raspistill -o /home/pi/sync/test/image_%04d.jpg --nopreview -tl 1000 -t 0 -a 12

Answer 1

Simple workaround using shell script. Example taking 10 pictures, 1 second apart. Change to accommodate for different needs.

#!/bin/bash

NUM=10
DELAY=1

while [ $NUM -gt 0 ]; do

    DATE=$(date +"%Y-%m-%d_%H%M")
    raspistill -o /home/pi/camera/$DATE.jpg

    let NUM=NUM-1
    sleep $DELAY

done

Daniel, you should update raspistill using apt-get. The timestamp now updates on each captured image.
