h1. Running QtMediaHub on Trident Shiner
#Redirect [[Running QtMediaHub on Trident Shiner]]
 
== Assumptions ==
 
# Qt 4.8.0 is configured, built and installed as per "Trident Shiner":http://wiki.qt.io/Shiner
# Can run "GstTsPlayer" or "miniplayer" on reference board to test media playback alongside any simple OpenGL ES 2.0 application
# The video playback plane is behind the graphics plane
# "QTDIR" and "PATH" environment variables are set to use Qt 4.8.0 cross compiled and installed for Trident Shiner in your build terminal
 
== Getting Source ==
 
You can get the latest source code from gitorious "https://gitorious.org/qtmediahub":https://gitorious.org/qtmediahub.
You can use "sync-to-head":http://gitorious.org/qtmediahub/qtmediahub/blobs/master/scripts/sync-to-head to update your sources to latest version
 
Note that we are in the process of moving the git repositories to the qt.io.
 
== Multimedia Playback Support ==
 
QMH uses "platform specific media player application" (in Trident Shiner's case it is either "GstTsPlayer" or "miniplayer" ) to have media playback facility.
This is achieved using "out of process integration" which means:-
 
## Using a "QProcess" object start platform specific media player
## Write to this "QProcess" object to pass playback commands
## Read from this "QProcess" object to receive feedback
 
Trident Shiner's GstTsPlayer specific media control integration can be found in files "mediaplayerTridentShinerGstTsPlayer.h":http://gitorious.org/qtmediahub/qtmediahub-core/blobs/master/src/mediaplayer/mediaplayerTridentShinerGstTsPlayer.h and "mediaplayerTridentShinerGstTsPlayer.cpp":http://gitorious.org/qtmediahub/qtmediahub-core/blobs/master/src/mediaplayer/mediaplayerTridentShinerGstTsPlayer.cpp
 
Trident Shiner's miniplayer specific media control integration can be found in files "mediaplayerTridentShinerMiniplayer.h":http://gitorious.org/qtmediahub/qtmediahub-core/blobs/master/src/mediaplayer/mediaplayerTridentShinerMiniplayer.h and "mediaplayerTridentShinerMiniplayer.cpp":http://gitorious.org/qtmediahub/qtmediahub-core/blobs/master/src/mediaplayer/mediaplayerTridentShinerMiniplayer.cpp
 
== Configuring ==
 
Use " -media-backend TRIDENT_SHINER_GSTTSPLAYER" configure option to enable multimedia playback capability of QMH using GstTsPlayer
 
<code>
cd /path/to/qtmediahub/
/path/to/qtmediahub/configure -media-backend TRIDENT_SHINER_GSTTSPLAYER
</code>
 
Use " -media-backend TRIDENT_SHINER_MINIPLAYER" configure option to enable multimedia playback capability of QMH using miniplayer
 
<code>
cd /path/to/qtmediahub/
/path/to/qtmediahub/configure -media-backend TRIDENT_SHINER_MINIPLAYER
</code>
 
== Building ==
 
Build QMH as follows
 
<code>
cd /path/to/qtmediahub/
make
</code>
 
== Installing ==
 
As installation of QMH on Trident Shiner reference board copy entire "qtmediahub" directory so that its path is exactly same as that on build machine.
 
== Running QMH on Qt 4.8 (QWS) ==
 
Setup QTDIR, QWS_KEYBOARD, QWS_MOUSE_PROTO and LD_LIBRARY_PATH environment variables as follows
 
<code>
export QTDIR=/path/to/installed/qt-everywhere-opensource-src-4.8.0/
export QWS_KEYBOARD="LinuxInput:/dev/input/event0" //Use appropriate device node
export QWS_MOUSE_PROTO="LinuxInput:/dev/input/event1" //Use appropriate device node
export LD_LIBRARY_PATH=${QTDIR}/lib/:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:"/path/to/qtmediahub/qtmediahub-core/hub/lib/"
</code>
 
Rum QMH as follows to use OpenGL ES 2.0
 
<code>
cd /path/to/qtmediahub/
/path/to/qtmediahub/qtmediahub-core/hub/bin/qtmediahub -qws -keyboard -mouse -display eglnullws:size=1280x720 -skin=confluence -overlayMode=true -opengl-usage=true -opengl-viewport=true -opengl-format-hack=false
</code>
 
Rum QMH as follows to use DirectFB
 
<code>
cd /path/to/qtmediahub/
/path/to/qtmediahub/qtmediahub-core/hub/bin/qtmediahub -qws -display directfb -skin=delphin -overlayMode=true -opengl-usage=false -opengl-viewport=false -opengl-format-hack=false
</code>
 
Rum QMH as follows to use Linux Frame Buffer
 
<code>
cd /path/to/qtmediahub/
/path/to/qtmediahub/qtmediahub-core/hub/bin/qtmediahub -qws -display -keyboard -mouse linuxfb -skin=confluence— -overlayMode=true -opengl-usage=false -opengl-viewport=false -opengl-format-hack=false
</code>
