Hoe te om uw Nokia N95 als draadloze Webcam te gebruiken

Linux Symbian

SmartCam verandert een Symbian Reeks 60 telefoon met bluetooth en camera in een webcam klaar om met uw PC te gebruiken. Het is open bronsoftware, die onder GPLv2 vergunning wordt gegeven en zal op Linux of Vensters lopen. Er zijn commerciële toepassingen die het zelfde ding zullen doen, maar ik geloof in het gebruiken van en het steunen van vrije, open bronsoftware waar mogelijk.

In dit leerprogramma zal ik SmartCam op Fedora 9 installeren aangezien de ontwikkelaar SmartCam reeds heeft getest en bevestigd dat SmartCam aan Ubuntu 8.04 werkt. Ja, gebruikt SmartCam Video4Linux API. Zie http://en.wikipedia.org/wiki/Video4Linux voor een lijst van compatibele toepassingen. Ik gebruik persoonlijk SmartCam met aMSN vrij vaak.

  1. Eerste dingen eerst, bezoek http://sourceforge.net/projects/smartcam/ en klik Download verbinding in de groene doos.

  2. klik om te vergroten

  3. Wij gaan de versie installeren Linux, zo klikken Download verbinding voor smartcam linux.

  4. klik om te vergroten

  5. De recentste versie Linux op het tijdstip van het schrijven is v2008.09.18.2. Download het zip archief en herinner waar u het bewaarde. Ik bewaarde binnen het ~/Download

  6. klik om te vergroten

    Ik zal de volgende stappen op de bevellijn doen aangezien het het compileren van een pitmodule voor SmartCam impliceert.

  7. Navigeer aan de folder waar u het zip SmartCam dossier opsloeg.

    [kmurray@radon ~] $ CD ~/Download

  8. Rits het archief open.

    [kmurray@radon Download] $ rits smartcam_v_2008.09.18.2.zip open
    Archief: smartcam_v_2008.09.18.2.zip

    het opblazen: smartcam/versie/phone_files/jSmartCam.jar
    [dossierlijst die wordt geknipt om plaats te besparen]

  9. Nu compileren wij de SmartCam pitmodule. U zult moeten ervoor zorgen dat u geïnstalleerdk headers van de pitontwikkeling hebt. In Fedora is het zo eenvoudig zoals yum installeer pit -pit-devel

    [kmurray@radon Download] $ CD smartcam/src/driver/
    [kmurray@radon bestuurder] $ maak - C /lib/modules/ `uname - de modules van r`/build M= `DOW `
    maak: Entering directory `/usr/src/kernels/2.6.26.6-79.fc9.i686′
    CC [M] /home/kmurray/Download/smartcam/src/driver/smartcam.o
    Building modules, stage 2.
    MODPOST 1 modules
    CC /home/kmurray/Download/smartcam/src/driver/smartcam.mod.o
    LD [M] /home/kmurray/Download/smartcam/src/driver/smartcam.ko
    make: Leaving directory `/usr/src/kernels/2.6.26.6-79.fc9.i686′

  10. Kernel modules usually live somewhere in /lib/modules/`uname -r`/. Just to keep things tidy, we’ll copy the module there.

    [kmurray@radon driver]$ sudo cp smartcam.ko /lib/modules/`uname -r`/extra

  11. Now update the module dependancies.

    [kmurray@radon driver]$ sudo /sbin/depmod -a

  12. Load the module.

    [kmurray@radon driver]$ sudo /sbin/modprobe smartcam

  13. Verify that it loaded.

    [kmurray@radon driver]$ /sbin/lsmod | grep smartcam
    smartcam 9880 0
    videodev 29824 1 smartcam

    [kmurray@radon driver]$ ls -l /dev/video*
    lrwxrwxrwx 1 root root 6 2008-11-15 13:59 /dev/video -> video0
    crw-rw—- 1 root root 81, 0 2008-11-15 13:59 /dev/video0

  14. As you may have noticed, we have a minor problem here. /dev/video0 is only accessible to root. Unless you plan on only using your webcam as root, which is a very bad idea, you need to change this. Rather than change the permissions of /dev/video0 every time you reboot, you can change your udev rules to allow all users to access /dev/video0.

    Using your favourite text editor, open /etc/udev/rules.d/50-udev-default.rules. I used vim.

    [kmurray@radon driver]$ sudo vim /etc/udev/rules.d/50-udev-default.rules

    Search for the video4linux stanza and change the line that reads:

    KERNEL==”video0″, SYMLINK+=”video”

    to this:

    KERNEL==”video0″, SYMLINK+=”video”, MODE=”0666″

  15. Remove and reload the SmartCam kernel module.

    [kmurray@radon driver]$ sudo /sbin/modprobe -r smartcam
    [kmurray@radon driver]$ sudo /sbin/modprobe smartcam

  16. Verify the permissions of /dev/video0.

    [kmurray@radon driver]$ ls -l /dev/video*
    lrwxrwxrwx 1 root root 6 2008-11-15 14:05 /dev/video -> video0
    crw-rw-rw- 1 root root 81, 0 2008-11-15 14:05 /dev/video0

    Now /dev/video0 is available to all users.

  17. Now compile the SmartCam application.

    [kmurray@radon driver]$ cd ../../src/app/
    [kmurray@radon app]$ gcc `pkg-config –cflags –libs gtk+-2.0 gthread-2.0` -lbluetooth smartcam.c -o smartcam

  18. Make the SmartCam application available to all users.

    [kmurray@radon app]$ sudo cp smartcam /usr/local/bin/

  19. Make the SmartCam icons available to all users.

    [kmurray@radon app]$ sudo mkdir /usr/share/pixmaps/smartcam/
    [kmurray@radon app]$ sudo cp icons/*.png /usr/share/pixmaps/smartcam/

  20. I also chose to create a menu entry for SmartCam under Applications -> Sound & Video. Click System -> Preferences -> Look and Feel -> Main Menu.

  21. click to enlarge

  22. This is where you add or remove custom Applications Menu entries.

  23. click to enlarge

  24. In the left pane, click on Sound & Video.

  25. click to enlarge

  26. Click the New Item button on the right hand side and fill in the fields as follows:

  27. click to enlarge

  28. Click the Choose Icon button at the top left and type /usr/share/pixmaps/smartcam in the file field at the top, then click on logo.png and click OK.
  29. The window should now look like this:

  30. click to enlarge

  31. Click OK and close the Menu Editor. Then click Applications -> Sound & Video and you will see a menu entry for SmartCam.

  32. click to enlarge

  33. Now that the computer is set up, you need to install SmartCam on your N95. The SmartCam zip file you downloaded earlier also contains the SmartCam application for your phone. The version you want to install on your N95 is in the archive under release/phone_files/SmartCamS603rdEd.SIS. See my previous tutorials on how to install applications on your phone if you are unfamiliar with the process (How to install N95 apps via USB | How to install N95 apps via bluetooth) Once you have SmartCam installed on your phone, you will find it in your Applications folder.
  34. You must start SmartCam on your computer first. Click Applications -> Sound & Video -> SmartCam.
  35. Now start SmartCam on your phone.
  36. Select Options -> Start
  37. If you have previously connected to your computer via bluetooth you will already see it in the list. If not, simply select More Devices. Either way, choose to connect to your computer.

  38. Here’s what it looks like on my phone and on my computer.


  39. At the time of writing, SmartCam only supports bluetooth connections. Hopefully in the future the developer will implement USB and/or Wifi as well. Either way, I still think SmartCam is a fantastic piece of software!

    how about windows??

  2. ninja says

    yea, could you explain it for windows please.

  3. MrGorefest says

    I love you!! :D
    it works great for me!!

  4. Patrick says

    Hi there,

    I already use a webcame (Logitech on my 80.4 Ubuntu machine). Can you tell me if changing the settings as shown above:

    KERNEL==”video0″, SYMLINK+=”video”

    to this:

    KERNEL==”video0″, SYMLINK+=”video”, MODE=”0666″

    Will have a negative effect on the webcam connectivity I already have?

    Many thanks.

    Patrick

  5. Des says

    i think it’ll work patrick

    i think its just a app for wireless access to the camera in the windows version,
    aka no compiling stuff or permission changes,

    most likley a install and run only feature

  6. Rob says

    hi, i have a nokia 6120 classic, supposedly compatible, any idea how to installto the phone?

  7. Patrick says

    Hi Des,

    Thanks for the information. Just had a look at the site your name links to.

    I’ve read a bit about Joomla before. Seem like a killer application.

    Regards,

    Patrick

  8. des says

    yeah, thanks

    it is actually quite good, fully customizable, a seperate admin area.

    soon as i have finished it i plan to use it as a online community with a flash gaming area.

  9. Patrick says

    Eeeek!

    No sure what is going on here. Any one with a clue-stick for me?

    Thanks.

  10. des says

    sounds to me like that gtk.h is missing (near the top of ur post)

    other than that im not too sure.
    i have basic build skills, but not too great on resolving things like that lol sorry.

    hope u get it working.
