Question about QCamera



  • I use 2013-09-25-wheezy-raspbian.zip for my Raspberry Pi.

    I refer to the following installed Qt5.2 rc1
    http://qt-project.org/wiki/Native_Build_of_Qt5_on_a_Raspberry_Pi

    I use Logitech C170 webcam.
    http://www.ebay.com/bhp/logitech-c170

    I can find /dev/video0 and
    I can get picture by
    #streamer -c /dev/video0 -s 640x480 -o picture001.jpeg

    but I run Qt Camera Example,I can't find any device.

    QCamera::availableDevices() returns an empty list.

    Some one can help me?

    thanks a lot.

    sorry for my english.



  • I update Qt version(qt 5.2 rc1 to qt 5.2 release).
    but the problem persists.

    I install qt 5.2 release to other x86 pc.
    OS is debian 7.2.0/[*] Standard system utilities/without X11.

    the same problem:
    #streamer -c /dev/video0 -s 640×480 -o picture001.jpeg is OK.
    QCamera::availableDevices() returns an empty list.

    I use QCamera in (Ubuntu 12.04.3 Desktop and Windows 7) is Ok.
    Does QCamera not supply embedded linux(-platfom eglfs)?

    sorry for my english.



  • After five months.I still unresolved.
    I update Qt(5.2.1 release) and RASPBIAN(Release date:2014-01-07).
    but the problem persists.
    Any help would be appreciated!
