This article explains how to use TI's DSP with GStreamer (e.g. on BeagleBoard). You need to have the DSP properly set up following BeagleBoard/DSP_Howto.



The easiest way to use the DSP capabilities is through the OpenMAX IL API, but in order to compile TI's implementation a special DSP library is required.


git clone git://gitorious.org/vjaquez-beagleboard/libbridge.git
cd libbridge
git co -b mybranch 23.3.3
make DESTDIR=/media/rootfs install


git clone git://gitorious.org/vjaquez-beagleboard/ti-omxil.git
cd ti-omxil
git co -b my-branch 3.28-2
make DBAPI_CFLAGS=-I/media/rootfs/usr/include/dspbridge \
     DBAPI_LIBS=-L/media/rootfs/usr/lib DESTDIR=/media/rootfs install


You would need to compile gst-openmax inside scratchbox:

git clone git://github.com/felipec/gst-openmax.git
cd gst-openmax
git checkout -b omap origin/omap
./autogen.sh --noconfigure
./configure --prefix=/usr
make DESTDIR=rootfs install

In order to get the omapfb usable for video playback you need this kernel argument:


And the GStreamer element:

git clone git://github.com/felipec/gst-omapfb.git
cd gst-omapfb
make DESTDIR=rootfs install


You should be able to use the gst-openmax elements now:

gst-launch-0.10 filesrc location="foobar.avi" ! avidemux ! omx_mpeg4dec ! omapfbsink
