Hi, To be honest I'm not an expert in embedded system and linux world, I'm novice here. What I have do until now for this project is installing gstreamer and dependencies directly from apt-get under Debian (arch/arm/at91-sam) with following packages (depending on media support needed) : - gstreamer-tools,gstreamer0.10,gstreamer0.10-alsa,gstreamer0.10-ffmpeg,,gstreamer0.10-fluendo-mp3,gstreamer0.10-fluendo-mpegdemux,gstreamer0.10-plugins-bad,gstreamer0.10-plugins-good,gstreamer0.10-plugins-ugly,gstreamer0.10-plugins-base. Then I've installed gmediarender from sources (gmediarender-0.0.6.tar.bz2) using standard install procedure (./configure, make, make check, make install). Now I can launch gmediarender without problem and play streams but the problem comes when playbin use the fluendo mp3 plugin, there the cpu usage is about 98% and it crash after a moment, I don't know how to configure the gst outputs plugins, somethimes playbin use another plugin depend on mp3 files readed and there the cpu usage is about 60% wic is more accceptable but stay high compraed to other mp3 player as cmus (here the cpu usage is 10%). I really don't understand why gstreamer use so much ressources and how to get this down to a more acceptable level. I'm sure the problem comes from gstreamer and fluendo plugin because if I use gst-launch with playbin I get the same problem > in QtGstreamer dependcy > > QtGStreamer requires the following software to be installed in order to > build: * CMake 2.8 or later <http://www.cmake.org/> * GStreamer 0.10.31 or > later <http://gstreamer.freedesktop.org/> With its dependencies: - Glib / > GObject <http://www.gtk.org/> and including gstreamer-plugins-base > (0.10.31 or later) * Qt 4.5 or later <http://qt.nokia.com/> * Automoc > <https://projects.kde.org/projects/kdesupport/automoc/> * Boost 1.39 or > later <http://www.boost.org/> * Flex <http://flex.sourceforge.net/> * > Bison <http://www.gnu.org/software/bison/> > > --> how to build boost and Glib for embedded ????????? > > > > ________________________________ > From: ML <lathion at altern.org> > To: gstreamer-embedded at lists.freedesktop.org > Sent: Tuesday, January 17, 2012 4:36 AM > Subject: Gmediarender > > > Hello, > ?? > I would like to make a dlna renderer device using an at91sam9g20 based > board. > ?? > I???ve installed debian an gemediarender without any problem, everything > works fine except that depend on wich mp3 file I play gstreamer consume > about 98% of CPU ressources??! > ?? > I???ve noticed that this problem append when gstreamer use fluendo mp3 > decoder (gstreamer0.10-fluendo-mp3), else if it use a different pipeline > (trought playbin) the cpu usage is about 65% wich is more acceptable (but > stay quite high), to compare if a play a mp3 file with cmus the cpu load > is 10%??!. > ?? > Could someone help me to solve this issue???
