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) alex@mercurio:/media/truecrypt1/svn/AirAndGround/Ground/Software$ dpkg -l | grep streamer | grep dev ii libgstreamer-plugins-bad0.10-0:amd64 0.10.23-7 amd64 GStreamer development files for libraries from the "bad" set ii libgstreamer-plugins-bad0.10-dev 0.10.23-7 amd64 GStreamer development files for libraries from the "bad" set ii libgstreamer-plugins-bad1.0-0:amd64 0.11.94-1 amd64 GStreamer development files for libraries from the "bad" set ii libgstreamer-plugins-bad1.0-dev 0.11.94-1 amd64 GStreamer development files for libraries from the "bad" set ii libgstreamer-plugins-base0.10-dev 0.10.36-1 amd64 GStreamer development files for libraries from the "base" set ii libgstreamer-plugins-base1.0-dev 0.11.94-1 amd64 GStreamer development files for libraries from the "base" set ii libgstreamer0.10-dev 0.10.36-1 amd64 GStreamer core development files ii libgstreamer1.0-dev 0.11.94-1 amd64 GStreamer core development files So please, add the proper dependencies and recompile the package to give all users a better debian experience :) -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.5.2 (SMP w/4 CPU cores) Locale: LANG=es_ES.UTF-8, LC_CTYPE=es_ES.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages libqtmultimediakit1 depends on: ii libasound2 1.0.25-4 ii libc6 2.13-35 ii libgcc1 1:4.7.1-9 ii libgl1-mesa-glx [libgl1] 8.0.4-2 ii libglib2.0-0 2.33.12+really2.32.3-1 ii libgstreamer-plugins-bad0.10-0 0.10.23-7 ii libgstreamer-plugins-base0.10-0 0.10.36-1 ii libgstreamer0.10-0 0.10.36-1 ii libpulse0 2.0-6 ii libqt4-network 4:4.8.2+dfsg-2 ii libqt4-opengl 4:4.8.2+dfsg-2 ii libqtcore4 4:4.8.2+dfsg-2 ii libqtgui4 4:4.8.2+dfsg-2 ii libstdc++6 4.7.1-9 ii libx11-6 2:1.5.0-1 ii libxext6 2:1.3.1-2 ii libxml2 2.8.0+dfsg1-5 ii libxv1 2:1.0.7-1 ii multiarch-support 2.13-35 libqtmultimediakit1 recommends no packages.
