Re: A simple intervalometer for the N900 (time-lapse photography)
 

Hi all.
Is there still the picture quality / halo issue in the new timelapse?
If it is, I think there is a solution for that. I've seen scripts (at the beginning of this thread) manually creating gstreamer pipeline, and obviously not putting image correction elements in it. There is a "camerabin" gstreamer element that (I think is used by the default camera app) and it uses everything so the image looks as it should.
The problem is I haven't found out how to actually take pictures (save images), camerabin should do it all by itself, it just needs to be triggered, and that is done with "user signals". I haven't yet found out how to use those, and currently don't have too much time, so I'm saying this here, it may help someone.

Version 0.2 of TimeLapse is out!
This release includes a stop button, a Progress indicator, while working, and switching to appropriate resolutions for each camera.

Get it while it's hot at http://timelapse.garage.maemo.org/

Keep that feedback coming.

@gimzo: thanks for the tip. I'll look into it. BTW, you can save a picture by using a filesink at the end of your pipeline. Also, you can use gst-inspect to see the properties of gstreamer elements.

With camerabin there is no pipeline (as I understand), it's all internal to it, and I haven't figured out yet how to "trigger" camerabin to save a picture.

"Unable to install 'timelapse'.
Incompatible application package."

gstreamer-tools already installed.

Advice?

Was not able to install .deb file using App Manager after clicking on file in garage but in Terminal, dpkg -i <filename>.deb worked just fine.

I am glad you took my UI idea and make use of it :) making me happy to see a part of my effort into this project :D

Re: A simple intervalometer for the N900 (time-lapse photography)
 

I would like to see "TimeLapse" linking up the picture into one easy video file .MP4 or something :) it might be hard to implement but it worth the pain to do it.

Things you would need to add:

- higher full size resolution of 5MP, Lanscape wide screen mode
- AUTO FOCUS needed + flash support
- Live updating camera for easy focusing using Live Focus! (dispite an annoying behaviour of the Live Focus that pissing me off)

-Preview button should let the camera do a LIVE feed (FULL SCreen) not a quick snapshot, this way we can use Live Focus to get the best possible focus before taking the TimeLapse..

That's what camerabin does, someone just needs to implement it.

On making video automatically, I hope there stays the option to just make images, I prefer to do video where I can have full control over it.
It would probably be easy to make mjpeg video, and could easily be transcoded to something else

Re: A simple intervalometer for the N900 (time-lapse photography)
 

I hear you guys, i'm looking deeper into gstreamer, especially that camerabin plugin. it seems to be exactly what we need. Thanks gimzo.

if anyone is interested, here's some good documentation about signals in gstreamer;

http://library.gnome.org/devel/gobje...o-signals.html

which is what you need to operate camerabin (and appropriate callbacks, of course).

Hopefully I'll have news soon...

I just stumbled upon this:
http://blogs.igalia.com/magomez/2010...igicam-and-qt/

Looks like it could be of use for this.

Re: A simple intervalometer for the N900 (time-lapse photography)
 

yes, I'm not sure why that is. I think the .deb needs to be in a different format for the app manager. I'll look into it.
just remember that to remove, you also need to use dpkg -r timelapse

In other news, I'm getting the hang of gstreamer and I already have a live preview, instead of static pics. So, no more gst-launch!
A couple of questions for the community:

1) do you think the camera should auto focus every shot or just once in the first one?
2) how the hell am I going to get all the controls for the camera (brightness, exposure and so on) in the ui? any ideas?
3) this also means that HDR pictures are going to be possible! need a mode switch button somewhere...

expect good things soon
