technically it would be good to have video codecs on the dsp. if this is not
offered at the time its needed, one has to look for alternatives. most of this
is business related and you will find out about that when your trying it :(

That would be a bit naive. The amr11 that is on the TI OMAP2420 has vector
operations and you can only get good performance if you can make use of them.
