first of all I would like to thank the development of this app! :)

Motion detection is working fine with stock camera app, but the timelapse doesn't take any picture at all (tested with stock camera and FCam). Do you have any idea what I am doing wrong...?

Thanks,

jm

hey cheers -- haven't done much to this in yonks :p

Yeah in my experience the timelapse bugs are more to do with the somewhat buggy native alarmd library than anything else -- I was trying to avoid using cron unneccesarily, but maybe I should switch for stability.....

Anyhoo, let me see if I can actually help or not:
* What params did you set for the timelapse?
* Were the relevant alarm cookies showing in the timelapse window?

Hi,

thanks for your answer and help :)

I attached 2 images about the configuration.
*I just wanted to take pictures, so I set 1 minute time interval, not to convert to video.
*What are the relevant alarm cookies...? :) Those that let me set time interval...? That is why I attached the images, maybe this could help...

Thanks,

jm

Re: [Announce] WatchDog - Motion Detector + Time Lapse

The alarmd cookies are the listed items on the second image you provided -- these tell the alarmd daemon: when to run, what to run, and who set the alarm.

So right now you've just confirmed that the cookies are being set properly and read from alarmed properly, but unfortunately alamred is not processing them for some buggy reason I've seen before that comes with executing custom scripts....

This leaves me with two options:
* 1 . write my own background daemon, which would be overkill
* 2. Use cron, which is nice and easy but I have no idea how reliable or resource hungry it is.

I'll try and find some time to play with this over the coming months, but no promises as usual. Thanks for the feedback anyhow

that is OK, tetris11_, thanks for your reply and effort! :)
I shall make things manually until then :)

cheers,

Re: [Announce] WatchDog - Motion Detector + Time Lapse

A quick fix until then would be to install cron, phone-control, and imagemagik and run:

TimeLapse.sh:
=============

Code:

#!/bin/bash



# Edit these

cap_script=/home/user/MyDocs/cap_script.sh

cap_dir=/var/tmp



an_script=/home/user/MyDocs/animate_script.sh

output_anim= $cap_dir/output_animation.gif



every_N_min=20

between_hour="11-12"



####################





# Make capture script

echo "

#!/bin/bash

phone-control --capture $cap_dir/`date +%Y_%m_%d-%H_%M_%S`.jpg

" >  $cap_script



# copy+backup current crontab

crontab -l  > old_cron.txt

cp old_cron.txt current_cron.txt



# Make the animate script that also restores the previous cron (and deletes the timelapse job)

echo "

#!/bin/bash

convert   -delay 20   -loop 0   $cap_dir/*.jpg  $output_anim

crontab old_cron.txt

rm old_cron.txt

" >  $an_script





# The following will execute the capture script "every N minutes" between the hours of "between_hour" just for today



echo "#min  hour   dom  mon dow year" >> current_cron.txt

echo " */$every_N_min   $between_hour   `date +%d\ %m\ %w\ %Y` $cap_script >> current_cron.txt



# Add animation script an hour after it runs to cron

echo " 0   $(( `echo $between_hour | egrep "[0-9]+$"` + 1 ))   `date +%d\ %m\ %w\ %Y`  $an_script >> current_cron.txt





# Write new crontab

crontab current_cron.txt

rm current_cron.txt

Re: [Announce] WatchDog - Motion Detector + Time Lapse

great app，keep n900 go on...

Hi tetris11_,

thanks for the reply and fix!

I was wondering about using gst-launch with "sleep x seconds".

EDIT: OK, forget about gst-launch; I'm unable to take apropriate pictures: the results are greenish and dark even with the back camera...

EDIT: My bad, it is possible to take fine pictures, just need to use the appropropriate commands: http://wiki.maemo.org/Phone_control#...h_front_camera

Cheers,

jm

Re: [Announce] WatchDog - Motion Detector + Time Lapse

Hello!

Is it only for me or the app wont start?

Re: [Announce] WatchDog - Motion Detector + Time Lapse

no no, this is normal...

It's unable to allocate enough memory and so it just... doesn't.

You can ask the kernel to overcommit memory, or kill a few resource-hogging background processes and see if that works...

Neat app, huh?

Re: [Announce] WatchDog - Motion Detector + Time Lapse

Hi.
I'm testing this app, but I can't set the white threshold above 4999: it complains with:

Code:

White needs to be a valid integer

The command line looks like:

Code:

/opt/watchdog/bin/watchdog -c -d -s 1280 960 -w 5999 -t 30:00

Is there a workaround for this?

Regards.

Re: [Announce] WatchDog - Motion Detector + Time Lapse

thats odd, but is likely a commandline parsing error.

my N900 died a while back so development of this is fully halted , but you can fork the code and try to debug it yourself I reckon - check out the command line class and play around a bit.

if you're not so keen on that, then a temporary fix might be to change the order of arguments and see if that works.

sorry ....
