    webcam not working

    Hi guys
    I got a new laptop today, asus K53E. Everything works a dream, is just the webcam which is upsidedown for some reason.
    koli@koli-K53E:~$ lsusb
    Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
    Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 001 Device 003: ID 13d3:5120 IMC Networks

    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    koli@koli-K53E:~$

    as you can see it is not listed and i suspect it is a proprietary webcam/driver. Does anybody know any good how to to turn in the right way.
    Thanks

    Re: webcam not working

    1:What version of ubuntu are you running?
    2:if its a laptop the camera might not be usb,maybe try lspci.
    3:There is also a highly rated piece of software for webcams in the software center called cheese webcam booth that you might want to try when all is working

    Re: webcam not working

    Hi I got it working,
    Instructions as follow:
    Hi,

    Thanks for providing the requested information. I've just made
    a new (test) release of v4l-utils (which includes libv4l) which
    contains your laptop info in its upside down table, and as such
    should fix (work around) the upside down issue for you.

    You can download this new version here:
    http://people.fedoraproject.org/~jwr...0-test.tar.bz2

    1. Install
    ==========

    libv4l needs make, a working C-compiler (gcc), and libjpeg +
    its header files to build. If you don't have these you need to install them
    first. See your distributions documentation on how to install make and
    the compiler (often called development tools / chain). For libjpeg,
    you need to install the libjpeg62-dev under Debian/Ubuntu and the
    libjpeg-devel package under Fedora / RHEL.

    Howto install and test libv4l depends on your system. There are
    different instructions for if you have a 32 bit system or a 64 bit system.
    which is using multilib. A 64 bit system without multilib is the same as
    a 32 bit system.

    To find out what you have do:
    ls -d /usr/lib64

    If this command gives a "No such file or directory" error, use the
    Non multilib instructions, if this command is successfull, you likely have multilib.

    Note: I've received some reports that there us a /usr/lib64 directory on some 32
    bit installs of Ubuntu. If you're quite sure you are running a normal (32 bit) version
    of Ubuntu you likely are and you should follow the Non multilib instructions.

    Ok, so you have a multilib system, to find out which (dubbed Fedora and Ubuntu
    multilib, because those are the most well known examples, do):

    ls -d /usr/lib32
    If this command gives a "No such file or directory" error, use the Fedora multilib
    instructions. If this command succeeds use the Ubuntu multilib instructions. Note
    the ubuntu multilib instructions also apply to gentoo and the Fedora multilib instructions
    also apply to [open]Suse.


    Non multilib instructions:
    --------------------------
    tar xvfj v4l-utils-<version>.tar.bz2
    cd v4l-utils-<version>/lib
    make PREFIX=/usr
    sudo make install PREFIX=/usr

    Fedora Multilib instructions:
    -----------------------------
    Basic 64 bit install:
    tar xvfj v4l-utils-<version>.tar.bz2
    cd v4l-utils-<version>/lib
    make PREFIX=/usr LIBDIR=/usr/lib64
    sudo make install PREFIX=/usr LIBDIR=/usr/lib64

    If you also want to use 32 bit apps (such as skype), you
    will need to have the 32 bit libc headers installed, on Fedora
    this can be done like this:
    Fedora 10-: "sudo yum install glibc-devel.i386"
    Fedora 11: "sudo yum install glibc-devel.i586"
    Fedora 12+: "sudo yum install glibc-devel.i686"
    [open]Suse: install glibc-devel-32bit and gcc-32bit

    Then do:
    make clean
    make PREFIX=/usr CFLAGS=-m32 LDFLAGS=-m32
    sudo make install PREFIX=/usr

    Ubuntu Multilib instructions:
    -----------------------------
    tar xvfj v4l-utils-<version>.tar.bz2
    cd v4l-utils-<version>/lib
    make PREFIX=/usr
    sudo make install PREFIX=/usr

    If you also want to use 32 bit apps (such as skype), you
    will need to have the 32 bit libc headers installed, on Ubuntu
    this can be done like this:
    sudo apt-get install libc6-dev-i386
    On gentoo this can be done like this:
    sudo emerge -v app-emulation/emul-linux-x86-compat
    Then do:
    make clean
    make PREFIX=/usr CFLAGS=-m32 LDFLAGS=-m32 LIBDIR=/usr/lib32
    sudo make install PREFIX=/usr LIBDIR=/usr/lib32


    2. Testing
    ==========
    You have a chance that your webcam app use libv4l or have an appropriate
    script starting it. In that case you don't have to do anything. Just run
    the application. This is the most common situation with Ubuntu and Fedora
    packages. If your problem remains unsolved, then your app might not use libv4l.
    In that case start the application from a terminal like this:

    Non multilib:
    ----------------
    LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so <your favorite webcam app>

    Note on Ubuntu sometimes skype is using a wrapper script, so if skype
    does not work try:
    LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype.real

    Fedora multilib:
    --------------------
    For 64 bit applications (allmost all apps):
    LD_PRELOAD=/usr/lib64/libv4l/v4l1compat.so <your favorite webcam app>

    For 32 bit applications (you only need it for proprietary softwares, which
    don't have a 64 bit version, like skype):
    LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

    Ubuntu multilib:
    --------------------
    For 64 bit applications (allmost all apps):
    LD_PRELOAD=/usr/lib64/libv4l/v4l1compat.so skype

    For 32 bit applications (you only need it for proprietary softwares, which
    don't have a 64 bit version, like skype):
    LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype

    Note on Ubuntu sometimes skype is using a wrapper script, so if skype
    does not work try:
    LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype.real


    Please let me know if this version of v4l-utils turns the image the
    right way up for you.

    Thanks & Regards,

    Hans

    Re: webcam not working

    Hi

    I have the very same USB ID for my (upside down) webcam on Asus. This took care of it (while installing the latest libv4l-0):

    sudo add-apt-repository ppa:libv4l/ppa
    sudo apt-get update && sudo apt-get dist-upgrade -y

    Worked for me on a Asus A53E laptop.

    Good luck.
