ffmpeg and xvid are available as plug-ins for
GStreamer and presumably work on Maemo 2008. What I
meant is that they presumably use ARM instructions.
The point is whether they ought to be modified to make
use of the DSP part of OMAP2420 to improve

Again, the point is the difference in performance with
/ without the DSP part of OMAP 2420. TI says that if
you use the DSP part you can get 30fps. If the current
implementations of media players do not use the DSP
part and only ARM, what is the performance?

I would be surprised if there is no software that uses
such a powerful processing element for media playback.
