How to verify dsp is working?

I managed to install Gstreamer dsp successfully after following the
instructions in http://elinux.org/BeagleBoardUbuntu

I ran the command below to play video files.
$ sudo gst-launch playbin2 uri=file://(file)

The video quality does not seem to be noticeably better. Maybe it is
because the Xorg omapfb Drivers are already quite good. Or maybe it is
because the sdcard is not fast enough. Is there some way to verify
that gst-dsp is actually working properly?

Thank you.

How to check it in Android (say 2.3 dsp)?

Thanks

It is strange that after running "sudo dsp-load", what I got are load
and frequency remains at 0 when playing video using gstreamer (sudo
gst-launch playbin2 uri=file://(file) ). Does this mean that gst-dsp
is not installed properly? Yet, when I ran "lsmod", I could see
modules like bridgedriver.

I am not sure if this is the cause. During installation, there was a
minor problem. When I ran "create_dsp_package.sh", there was an error
about libstdc++.so.5 and libstdc++5 not available. I have libstdc++6
on Ubuntu 10.04 and apt-get cannot find libstdc++5. So, what I did was
to remove libstd_dependicy from the script. Is this a problem? Since
there was no compilation involved in create_dsp_package.sh, I think
libstdc should not be important.

It was an issue a few years ago with one of the sgx bin files and more
of a legacy check in the script..

As long as the firmware files are under /lib/dsp/* and sudo dsp-probe
works, the content your playing probally is outside the support
codec's..
