[Asterisk-video] RE: Video transcoding

I have been running ffmpeg/libavcodec h263 in a videoconference client in a 300 Mhz geode cpu, and over 10 simultaneous encoding/decoding in a P4 3GHZ with not much load (I don't remember the figures). 
It also depends on the fps and size of the video been encoded/decoded, for an H324M it would be easy.. :)
Probably transcoding many h264s at high rates it's not possible, but running a big number of h261/h263  is. 
Another question is if it's really needed or not..

I see it much more useful an array of dsp on a pci card or similar. Perhaps it's a good idea to make it open so new implementations could be added in the future..

Greetings
