IGEP gst framework it's based on TI DVSDK. It's modified version for provide all DSP essential packages and the [[GStreamer|gstreamer]] DSP plugin for use it in IGEP platforms. <br>

The package is available at the Official ISEE site, at the IGEPv2 [http://isee.biz/component/zoo/item/igep-dsp-gst-framework download area].
http://isee.biz/component/zoo/item/igep-dsp-gst-framework Download the package and uncompress this package as normal user in your desired directory ('''''don't use sudo command for decompress this file''''')
= How to Build<br> =
You should edit Ensure that you've the file Rules.make and update right toolchain installed (you can install it using the script included in the root package path and toolchain pathdirectory install_toolchain.sh)<br>
RulesExecute the script: build_configure.makesh<br>

<br> <pre>make install</pre> Inside the target directory you've two new directories(default:
<br> dm3730-binaries (modules, kernel ... for DM3730)
<br> omap3530-binaries (modules, kernel ... for OMAP3530) Copy target directory to your board as:<br> <
/pre>
cd targetscp -r dm3730-binaries <remote_user>@<IGEP IP>:/home/<your_desired_directory>scp -r scripts <remote_user>@<IGEP IP>:/home/<your_desired_directory> Also included After that you'
ve the IGEP Xloader and the configuration file.</pre> Enter re ready for copy it inside your
IGEP board
and go to gstreamer directory normally inside /usr/lib/gstreamer-0.
10 and create two symbolic links from this directory to your files:<br>
cd /usr/lib/gstreamer-0.10 ln -s /home/<your_desired_directory>/cs.x64P ln -s /home/<your_desired_directory>/libgstticodecpluginAll build binaries will reside inside the target directory under your selected platform, copy all the content inside your board.so
or copy the files directly as inside target directory locationIGEP-X-Loader and Linux kernel have self own howto about build and install it ...
