Nokia have provided the TI DSP codecs for decoding. These will not do 720p like the HD pack but an enterprising dev or company could create better optimised codecs and sell them on ovi store or provide them in extras.

I guess the TI DSP codecs are closed, but is there documentation on how to access them from outside of gstreamer?
And of course, what redenisc asked, whether third party apps can at all access them or if it's locked to gstreamer

The code could be adapted for other media players like mplayer and vlc. Just a matter of work.

That was not my point. Yes, the code is open-source, and nothing prevents mplayer, VLC or whoever else from re-implementing it (except time constraints).
But that does not prove that access arbitration will work and the device won't burn in flames if say mplayer tries to use the DSP at the same time as gstreamer.

Oh I seriously hope either VLC or MPlayer gets some DSP code.

I'm sorry, I normally consider myself pretty tech-savvy, but could someone explain what "access arbitration" is, how it relates to this discussion and what it has to do with my future N900 dying in a fire?
