Re: [maemo-developers] Detecting N800 camera position
Hello! you could also check: /sys/devices/platform/gpio-switch/cam_act/ /sys/devices/platform/gpio-switch/cam_turn/ I'm really lost in detecting and changing camer position. My application uses gstreamer but is not a GTK application and thus not actively using the gtk, gnome, osso,hildon infrastruture. Using gconfv4l2src works in that I get an image but the video image does not automatically flip horizontally. As a next step I tried to add a notifier for the gconf configuration value. But this does not work. The notifier callback is never called. Perhaps because I do not use a gtk main event loop. As a next try I tried to use gconf directly to poll the state. But this does not work either. After that I checked the /sys/-values and they change. So now I will regulary poll this values as I don#t like it but it works solution. However how to I flip the video manually using gstreamer? P.S.: And yes, image/video flipping does work in principle as tested with the video conferencing tool. P.P.S.: If I got this working I will release a small, simple GUI driven camera application... -- Gruß...

Re: [maemo-developers] Detecting N800 camera position
Hello again Tim! I suppose my code didn't worked for you. It's something very strange what's happening here... but also I think I can help you. When I first discovered this gconfv4l2src stuff I really do many things to try to achieve this thing. As I was trying to do it with python, I didn't know exactly how to do it like I'm going to explain but in C it should be straighforward. AFAIK v4l2src element implements the GstVideoOrientation[1] interface. So with gst_video_orientation_set_hflip function and polling sysfs entry you should be able to make it work (not sure if its hflip or vflip function). Also, I suggest you to watch more in-depth what's the problem with gconfv4l2src. I think the kernel sends a message to userspace which is injected by a daemon through DBUS, and this should be catched by another daemon which modifies the gconf key. Maybe for some reason these daemon dies or is never launched on startup. I'm sorry I can help you more with the names of this daemons, but I think you should have something wrong in your system. Hope at least it helps! Bye. P.S: I know I said to you I would like to help on this project, but you know, sometimes there isn't many time to be involved on this things. Also I would be happy to see your project launching a first version and maybe in the future colaborate on some parts.

I was trying to write a simple program, and I would like to know if there is some way to detect when the camera gets rotated to the point that it should flip the image as does the internet call application that comes with OS2007. Fortunately, there are two very useful self-explainatory boolean gconf keys for these things: 1. /system/osso/af/camera-is-out 2. /system/osso/af/camera-has-turned BTW, since it's gconf, you can set-up notification callback in your applications for these events to, in case you need that. Hope this helps! P.S There is a D-Bus way to do the same thing as well but i think gconf is much simpler to deal with as compared to D-Bus. -- Regards, Zeeshan Ali Design Engineer, SW Open Source Software Operations Nokia Multimedia ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

What would be needed to launch an application other than messenger when a camera-is-out event takes place? On garage project malomo [1] we've thought of making a control panel applet to choose between launching messenger or camera application.
