| == Assumptions ==
| |
| | |
| # Qt 4.8.0 is configured, built and installed as per [http://wiki.qt.io/Shiner Trident 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 [http://gitorious.org/qtmediahub/qtmediahub/blobs/master/scripts/sync-to-head 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 [http://gitorious.org/qtmediahub/qtmediahub-core/blobs/master/src/mediaplayer/mediaplayerTridentShinerGstTsPlayer.h mediaplayerTridentShinerGstTsPlayer.h] and [http://gitorious.org/qtmediahub/qtmediahub-core/blobs/master/src/mediaplayer/mediaplayerTridentShinerGstTsPlayer.cpp mediaplayerTridentShinerGstTsPlayer.cpp]
| |
| | |
| Trident Shiner's miniplayer specific media control integration can be found in files [http://gitorious.org/qtmediahub/qtmediahub-core/blobs/master/src/mediaplayer/mediaplayerTridentShinerMiniplayer.h mediaplayerTridentShinerMiniplayer.h] and [http://gitorious.org/qtmediahub/qtmediahub-core/blobs/master/src/mediaplayer/mediaplayerTridentShinerMiniplayer.cpp 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
