Er, no idea, would have to read the article.

For video? Yeah that would be great, but that would require either:

a) Someone to develop the DSP codecs for the dsp-gw [1] and ARM side wrappers.

b) Nokia to provide the TI DSP stack (dsp codecs, arm/dsp-bridge,
openmax wrappers), and support for the N8x0 (gst-openmax).

c) TI to provide their DSP stack publicly and some maemo hackers
provide support for the N8x0.

I can't comment on what has more chances to happen, but it's always
good to shout to the companies for answers.
