BeagleBoard/gst-dsp

Texas Instruments provides DSP algorithms for the OMAP 3 platform used in a number of devices like BeagleBoard and N900.

The gst-dsp project aims to provide GStreamer elements to take advantage of those algorithms. The list includes video/image decoders and encoders.

Unlike other similar projects there are no dependencies (no openmax, no libdspbridge).

The features include:


 * video decoding (MPEG-4, H.263, H.264)
 * video encoding (MPEG-4, H.263)
 * image encoding (JPEG)
 * zero-copy

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 DSP howto.

Setup
Follow carefully the DSP howto, and ensure that the TI's DSP binaries are properly installed.

GStreamer
Install GStreamer for your board.

If your cross compilation environment doesn't provide it, you can follow this generic recipe: How to compile for embedded.

gst-dsp
Then, using your preferred cross compilation environment, checkout and compile the project.

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

gst-omapfb
In order to display the video playback through the DVI interface, you should also install gst-omapfb.

Testing
gst-launch playbin2 uri=file:///big_buck_bunny_480p_surround-fix.avi
