[Ffmpeg-devel] Porting to TI DM642 DSP

I'd like to use the ffmpeg libraries on a TI DM642 DSP.  Can anyone 
comment on the feasibility of doing this, and perhaps provide an 
overview of the hurdles I need to overcome?   Initially, I see two major 

1)  Compiling -- I imagine #include statements will need to be modified 
to work with TI's tools.  I would like to avoid major modifications to 
the source with #ifdef statements (and I believe this is the philosophy 
of ffmpeg developers).  Additionally, some types may not be supported 
with TI's compiler.

2)  Optimization -- Initially, I just want to build without 
optimization.  Then (assuming performance is less than great), I intend 
to optimize certain primitives (e.g. DC T), preferrably by using TI's 
versions of these primitives.

Can anyone comment on the above two challenges (or others), and 
recommend ways to overcome them?  Perhaps someone that ported to another 
platform would be able to make some recommendations?

Thanks in advance for your help.
