We are using Beagleboard to make streaming audio & video, we are using
gstreamer Framework, we have some problems when executing some demos:

root at overo:/usr/share/ti-codec-combos#

gst-launch --gst-debug=1 filesrc location

We have a problem that gstreamer failed to determine target board.

Anyone can help about issue?
