Package: libqtmultimediakit1
Version: 1.2.0-3
Severity: normal
Dear Maintainer,
I was developing an application that access webcams directly through QtMobility
API.
This framework has a number of backends that allow acces to cameras in a multi-
platform manner.
With the current version from repositories i was noticing a very high CPU
usages (246% , various threads hoggin 4 CPUs in my machine)
In the qt bug tracking (https://bugreports.qt-
project.org/browse/QTMOBILITY-1923) i found a reference to the fact that
qtmobility can use two backends in linux : gstreamer camerabin and video4linux
..
The latter seems to be very inefficient in terms of CPU usage.
After making an apt-source and compiling myself qtmobility i checked that the
configure test where failing to detect gst-photography support, altough i have
installed all the build dependencies for the package.
After tampering a bit with my system and after installing this -dev files the
configure test passed and the qtmultimediakit library built this way show
considerable less CPU usage
(-dev packages installed)
