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
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.
raspistillyou can always use your own script to invoke it to take one image at any given time with a filename of your choosing. Essentially like this (shown under "Bash script") thus getting the timestamp you'd like. – Ghanima♦ Jan 5 '16 at 16:55
