[Theora-dev] RE: DSP stamp

[John Kintree]

I'm glad you spoke up, Aaron, and let the list and Andrew Seddon know of your 
interest.  Working on a hardware implementation of the theora codec on 
multiple fronts makes sense to me.  Andrey Fillipov is now at 70% completed 
with the FPGA implementation he is doing for Elphel's network camera, but 
that is without motion compensation or audio.  

Thomas Vander Stichele is interested in the DSP Stamp, also, according to the 
message he posted to the list on 11/11/04.
Regards,
John
