=GStreamer with GST-OpenMax=
==Introduction==
This how-to will describe how to setup and use [http://freedesktop.org/wiki/GstOpenMAX gst-openmax] a GStreamer plug-in that allows communication with OpenMAX IL components. OpenMAX IL is an industry standard that provides an abstraction layer for computer graphics, video, and sound routines.
==Requirements==
==Downloads==
==Functional Codecs==
omx_mp3dec
==Building OpenMAX IL==
*Download the source code to a temporary directory
<pre>
mkdir -p /tmp/omx
cd /tmp/omx
wget http://downloads.sourceforge.net/omxil/libomxil-bellagio-0.9.0.tar.gz
</pre>
*Extract the tarball
<pre>
tar -xvf libomxil-bellagio-0.9.0.tar.gz
cd liboxmil-bellagio-0.9.0

./configure --prefix=$HOME/omx
</pre>
*Build and install

<pre>
make
make install
</pre>

==Using GST-OpenMAX==
===Setting the environment===* Set the location to our libraries<pre>export GST_PLUGIN_PATH="$HOME/omx/lib/gstreamer-0.10"export LD_LIBRARY_PATH="$HOME/omx/lib"</pre> *Register omx codecs*NOTE: This command must be run by the user who complied the package<pre>~/omx/bin/omxregister-bellagio -v</pre> *Check if the codecs have been sucessfully successfully loaded

</pre>
===Playing a song===
*Playing a mp3 file "test.mp3"
<pre>

==Known IssuesFAQs==* Will there be support for Fedora 18?** We are currently attempting to build our package on the F18 platform but have run into some issues getting our testing environment setup. ===Errors===* (gst-launch-0.10:18996): WARNING **: libomxil-bellagio.so.0: cannot open shared object file: No such file or directory** You did not set the location to the libraries, refer to [http://zenit.senecac.on.ca/wiki/index.php?title=RPM_Packaging_and_support_for_OpenMAX&action=submit#Setting_the_environment Setting the environment] * (gst-plugin-scanner:18985): WARNING **: could not find config file '/home/ryan/.config/gst-openmax.conf'.. using defaults!** You did not install OpenMAX IL, refer to [http://zenit.senecac.on.ca/wiki/index.php?title=RPM_Packaging_and_support_for_OpenMAX&action=submit#Building_OpenMAX_IL Building OpenMAX IL]
