Hi Guys,
Newbie here, who posted his first Sailfish app to the Harbour today :-) I've
already posted this at together.jolla.com, but was kindly asked to post app
development related questions to this mail list instead. So here it goes:
I'm trying to detect the available cameras in the device, and get some basic
properties of them, like still image resolution (which should equal to image
sensor resolution), video recording resolution, presence of LED flash, etc.
I'm trying QT calls from C++ code like this:
QCameraInfo::defaultCamera().deviceName()
QList<QCameraInfo> cameras = QCameraInfo::availableCameras();
QList<QByteArray> devices = QCamera::availableDevices();
It doesn't seem to work at all on the Jolla Phone, it runs very slowly and
causes the app to hang for seconds. And it returns 9 camera devices, from
/dev/video0 through /dev/video8 on the Jolla Tablet, which is even more
strange. What am I doing wrong?
I've tried the QML way as well, but it acts similarly bad as the C++ way.
Here's the code that fails to work:
import QtMultimedia 5.4
Page {
property int availCam: QtMultimedia.availableCameras.length
}
It takes a long time to return 0 as length, just like under C++. Maybe the
QCamera implemenation in SFOS cannot provide the list of available cameras
at all? If so, then how can I detect the presence of cameras, and how to
select the front or rear camera, to let me then detect its capabilities?
Thanks,
Tamas
